Description

{Charging/discharging system and data recovery method using the same}

The present invention relates to a charging/discharging system and a data recovery method using the same, and more specifically, to a charging/discharging system capable of maintaining the continuity of process data in a predetermined event (an event in which power is restored after a power outage, an event in which power is resumed after a user-forced stop, etc.) and a data recovery method using the same.

With the development of electrical and electronic technology, the use of portable electronic devices that are small and light but have various functions is rapidly increasing. Batteries are generally used as a power supply device for the operation of portable electronic devices, and secondary batteries that can be recharged and reused are mainly used.

Secondary batteries such as nickel-cadmium batteries and lead-acid batteries can be used immediately after production, so chargers and dischargers were only needed for performance evaluation. However, in the case of lithium secondary batteries such as lithium-ion batteries and lithium polymer batteries that are widely used recently, the performance of the battery is completed only after the process of performing a certain charge and discharge after production, that is, the formation process, so chargers and dischargers have become essential equipment in the production line of secondary batteries.

The charger/discharger performs the function of imparting the characteristics of a secondary battery by repeating the charging and discharging process several times so that the first battery assembled during the secondary battery production process can store electric energy. As the demand for secondary batteries rapidly increased and the supply increased, the number of chargers/dischargers that perform the charging/discharging function in the secondary battery production stage also increased.

Conventional chargers are manufactured with a structure that can implement the function of charging and discharging multiple secondary batteries simultaneously.

In order to charge and discharge multiple secondary batteries at the same time, a tray is used in the charger/discharger to mount a certain number of secondary batteries, and a number of channels corresponding to that number are formed and used in the charger/discharger circuitry.

Typically, when a user starts a process with a dedicated application program for the PC's equipment (i.e., a charger/discharger), the charger/discharger receives a schedule related to the process from the PC, stores it internally, and then starts the process according to the schedule related to the process. The charger/discharger transmits the status of the process in progress to the PC in real time, and the PC displays the received data in real time, and the charger/discharger stores the process data as a file internally. At regular intervals, the PC receives process data from the charger/discharger and stores it in the form of a file.

Meanwhile, an uninterruptible power supply (UPS) is installed to enable the charger to save process data even if there is a problem with the power supply.

However, if the UPS becomes aging or has a problem and cannot store process data, data loss occurs, and once the process is completed, data continuity for the same process is lost.

The matters described in the background art above are intended to help understand the background of the invention and may include matters that are not publicly available prior art.

Prior art 1: Republic of Korea registered patent No. 10-0254785 (PLC data backup device and method) Prior art 2: Republic of Korea registered patent No. 10-0950235 (device including flash memory, robust against power failure)

The present invention has been proposed in consideration of the above-mentioned conventional circumstances, and its purpose is to provide a charging/discharging system and a data recovery method thereby, which grants data continuity so that newly started process data can be stored from the last point of the previous process data when a predetermined event (recovery after power failure, resumption after user-forced stop) occurs during charging/discharging of a battery.

In order to achieve the above object, a charging/discharging system according to a preferred embodiment of the present invention includes: a charger/discharger which is connected to a battery and performs a process for the battery, generates measurement data, recovery data and result data related to the process according to a result of the performance, and outputs the recovery data; and an operating terminal which controls the operation of the charger/discharger and receives the recovery data output from the charger/discharger; wherein the operating terminal determines a data recovery reference point in time for a first process which was being performed by the charger/discharger and is currently suspended according to a user key input, and transmits the data recovery reference point in time together with a data recovery command to the charger/discharger, and the charger/discharger resumes the first process in response to the data recovery command, and generates result data which is continuous to the result data of the data recovery reference point in time based on the recovery data corresponding to the data recovery reference point in time and the measurement data of the resumed first process.

The above measurement data may include one or more raw data measured in real time or periodically during the process, the recovery data may include a value created by processing the measurement data, and the result data may include a value created by processing the recovery data.

The above charger may include a storage unit that stores measurement data, recovery data, and result data of the first process; and a control unit that performs a data recovery operation to provide continuity of result data based on recovery data corresponding to the data recovery reference point among the data stored in the storage unit when the first process is resumed.

The above control unit can generate recovery data at the current point in time by combining recovery data corresponding to the data recovery reference point in time and measurement data at the current point in time when the first process is resumed, and can generate result data at the current point in time by using the generated recovery data at the current point in time.

The recovery data corresponding to the above data recovery reference point in time may be the recovery data at the last saved point in time before the first process was forcibly stopped.

The recovery data corresponding to the above data recovery reference point in time may be the recovery data of a storage point in time selected by a user's key input from among the storage points in time at which the measurement data, recovery data, and result data of the first process are stored.

The above storage unit additionally receives and stores recovery data of a data recovery reference point in time from the operating terminal, and the control unit can perform a data recovery operation to provide continuity of result data based on the recovery data of the data recovery reference point in time stored in the storage unit.

The above operating terminal may include a storage unit that stores measurement data, recovery data, and result data of the first process from the charger/discharger; and a control unit that determines a data recovery reference point in time for the first process and transmits the determined data recovery reference point in time to the charger/discharger.

The above control unit can additionally transmit recovery data at the data recovery reference point in time to the charger/discharger.

The above control unit may include a data separation unit that separates recovery data and non-recovery data from the data set from the charger; and a time determination unit that determines the data recovery reference time point upon receiving a forced stop command of the first process by a user key input.

The above data recovery reference point may be the point in time at which the last recovery data was saved before the first process was forcibly stopped.

The above first process can be resumed after the second process is completed after the forced stop.

The above first process is a process in one channel among a plurality of channels, and while the first process is performed in the first channel and the second process is performed in the second channel, after the first process is forcibly stopped, the second process can be resumed in the second channel following the second process as the second process is completed.

Meanwhile, a data recovery method according to a preferred embodiment of the present invention comprises: a step in which a charger/discharger generates measurement data, recovery data, and result data related to a first process according to a result of performing a process on a battery and transmits them to an operating terminal; a step in which the operating terminal receives and stores the recovery data from the charger/discharger; a step in which the operating terminal determines a data recovery reference point in time for a first process that was performed by the charger/discharger and is currently suspended according to a user key input; a step in which the operating terminal transmits the data recovery reference point in time together with a data recovery command to the charger/discharger; and a step in which the charger/discharger resumes the first process in response to the data recovery command, and generates result data that is continuous to the result data of the data recovery reference point in time based on the recovery data corresponding to the data recovery reference point in time and the measurement data of the resumed first process.

According to the present invention having such a configuration, even if an event occurs in which the power of the charger/discharger is completely cut off and then restored, an event in which a user forcibly stops a first process and resumes the first process after completing the second process, an event in which the first process is forcibly stopped while performing the first process on the first channel and the second process on the second channel, and then the first process is resumed on the second channel after the second process is completed, data continuity can be provided in which newly started process data can be stored from the last point of the previous process data.

Hereinafter, with reference to the attached drawings, a preferred embodiment of the present invention will be described in more detail. In order to facilitate an overall understanding in describing the present invention, the same reference numerals are used for the same components in the drawings, and redundant descriptions of the same components are omitted.

Figure 1 is a drawing illustrating an example to which a charging/discharging system according to the present invention is applied.

The charge/discharge system (50) in Fig. 1 is a system capable of charging and discharging a battery such as a secondary battery.

The charging/discharging system (50) is connected to a power supply (10) and a battery (30), and may include a charging/discharging unit (20) and an operating terminal (40).

The power supply unit (10) can transmit a predetermined input power to the charger/discharger (20) and the operating terminal (40) within the charging/discharging system (50).

The power supply unit (10) can receive the discharge power of the battery (30) transmitted from the charger (20). In this case, the power supply unit (10) can output the discharge power of the battery (30) through the ground terminal.

The charger (20) can receive a schedule related to a process from the operating terminal (40), store it internally, and perform a process according to the schedule related to the process.

The charger/discharger (20) performs the function of imparting the characteristics of a secondary battery by repeatedly performing a charging/discharging process so that the assembled battery (30) can store electric energy.

The charger/discharger (20) can store various types of data (e.g., including measurement data, recovery data, and result data) according to the charging/discharging process in real time or periodically before a predetermined event occurs (i.e., during normal times), and transmit the stored data to the operating terminal (40) in real time or periodically. Among the types of data exemplified above, the measurement data and the result data can be collectively referred to as process data. Here, the event may include an event in which the power of the charger/discharger (20) is completely cut off and then restored, an event in which a user forcibly stops the first process in the middle and restarts the first process after the second process is completed, an event in which the first process is performed in the first channel and the second process is performed in the second channel, and when the second process is completed, the first process is forcibly stopped in the middle and restarted in the second channel.

Meanwhile, when a predetermined event occurs, the charger/discharger (20) can perform a data recovery operation to provide continuity of process data that can be stored from the last point of the previous process data (e.g., measurement data, result data) based on the data recovery reference point from the operating terminal (40) among the stored data. If the charger/discharger (20) additionally receives recovery data of the data recovery reference point together with the data recovery reference point from the operating terminal (40), the received recovery data can be utilized.

For example, in the case of the first event where power is restored after a power outage, the charger/discharger (20) can perform a data recovery operation to provide continuity of process data that can be stored from the last point of the previous process data based on the data recovery reference point from the operating terminal (40) among the stored data when power is restored after the power outage.

For example, if the second event is that the user forcefully stops the first process in the middle and resumes the first process after completing the second process, the charger/discharger (20) forcefully stops the first process in the middle and resumes the first process after completing the second process. In this case, the charger/discharger (20) may forcefully stop the first process according to the forceful stop command of the first process from the operating terminal (40) and may store the process data and recovery data of the first process up to the time of the force stop internally and then transmit them to the operating terminal (40). Here, the resumption of the first process may be performed together with the completion of the second process. When resuming the first process, the first process may be resumed based on the data recovery reference time from the operating terminal (40) among the previously stored data, but a data recovery operation may be performed to provide continuity of the process data that can be stored continuously from the last point of the previous process data.

For example, in the case of a third event that forcibly stops the first process (battery 1) in the first channel and performs the second process (battery 2) in the second channel, and then resumes the first process in the second channel when the second process is completed, the charger/discharger (20) forcibly stops the first process in the middle of performing the first process (battery 1) in the first channel and performs the second process (battery 2) in the second channel, and then resumes the first process in the second channel when the second process is completed. In this case, the charger/discharger (20) may forcibly stop the first process in the first channel in accordance with a command to forcibly stop the first process in the first channel from the operating terminal (40), and may internally store process data and recovery data of the first process up to the time of the forcibly stop, and then transmit them to the operating terminal (40). Here, the resumption of the first process in the second channel can be performed together with the completion of the second process in the second channel. When resuming the first process in the second channel, the first process in the second channel can be resumed based on a data recovery reference point from the operating terminal (40) among the previously stored data, and a data recovery operation can be performed to provide continuity of the process data that can be stored continuously from the last point of the previous process data.

Meanwhile, since the charger/discharger (20) can transmit the status of the process in progress to the operating terminal (40) in real time, in addition to the measurement data, recovery data, and result data exemplified above, status data can be transmitted to the operating terminal (40) in real time. For example, the status data may include the equipment status before the power outage, the equipment status applied after restoration, the starting point of the equipment status after restoration, the number of data to be stored after restoration, the last stored data number before the power outage, the idle status value before the power outage, the mode status value of the process before the power outage, the code value of the status before the power outage, the step number in progress before the power outage, the voltage value measured before the power outage, the current value measured before the power outage, the process time of the step before the power outage, the total progress time of the process before the power outage, etc. Examples of the status data are not limited to the examples above and may be more diverse. Such status data may help in the process execution at each event.

The battery (30) must go through a process of performing a predetermined number of charge and discharge cycles after manufacturing in order to exhibit its performance as a secondary battery. A charge and discharge system (50) is required to perform this charge and discharge process.

A battery (30) may be a device capable of storing or supplying electrical energy.

The battery (30) may be a secondary battery that can be repeatedly charged and discharged. For example, the battery (30) may be a lead-acid battery, a nickel-cadmium (Ni-Cd) battery, a nickel-hydrogen (Ni-MH) battery, a lithium-ion battery, and an all-solid-state battery, but is not limited thereto in the embodiment of the present invention.

A battery (30) may collectively refer to a battery cell including a cathode, an anode, an electrolyte, and a separator, a battery module including a plurality of battery cells, or a battery pack including a plurality of battery modules.

In Fig. 1, one battery (30) is shown as being connected to a charger (20), but it is also acceptable to view multiple batteries (30) as being connected to a charger (20), with one battery (30) connected to each channel.

The operating terminal (40) is connected to the charger/discharger (20) and can receive various data (e.g., measurement data, recovery data, and result data) according to the charging/discharging process from the charger/discharger (20) in real time or periodically and store them internally.

The operating terminal (40) can display the received data on the screen.

The operating terminal (40) can receive various data according to the charging/discharging process through FTP (File Transfer Protocol).

For example, in the case of the first event where power is restored after a power outage, the operating terminal (40) can transmit a user's data recovery command to the charger/discharger (20) after the power is restored, and can also transmit a data recovery reference point in time to the charger/discharger (20). Of course, if necessary, the operating terminal (40) can additionally transmit data necessary for data recovery (e.g., recovery data at the data recovery reference point in time) to the charger/discharger (20).

Here, the data recovery reference point is the point in time before the power outage, and can be arbitrarily determined by the user (administrator) as the power is restored, or can be automatically determined by the operating terminal (40).

The operating terminal (40) receives and stores data (e.g., including measurement data, recovery data, and result data) from the charger (20) in real time or periodically before a power outage. In this way, each time point at which data is received and stored is designated as a unique storage time point, and the received data can be stored for each storage time point.

However, when the user determines the data recovery reference point in time as the power is restored, since the data from the charger (20) before the power outage is transmitted to the operating terminal (40) and stored by storage point in time, the user can determine one point in time among multiple storage points as the data recovery reference point. The data recovery reference point determined in this way is input to the operating terminal (40), and the operating terminal (40) stores the data recovery reference point determined by the user.

Meanwhile, in the case where the operating terminal (40) automatically determines when the power is restored, since the data from the charger (20) is transmitted to the operating terminal (40) and stored at each storage time point before the power failure, the operating terminal (40) can automatically determine one point in time (for example, the point in time immediately before the power failure) among the multiple storage times as the data recovery reference time point. The above-described example is only one example and is not limited thereto. That is, if necessary, the operating terminal (40) can determine a point in time other than the point in time immediately before the power failure as the data recovery reference time point according to programming.

In this way, when the data recovery reference point is determined, the operating terminal (40) can display the flag value at that point as “1.”

Therefore, after the restoration, if a user's data recovery command is input, the operating terminal (40) can transmit the data recovery command together with the data recovery reference point determined by the user or the data recovery reference point automatically determined in advance by the operating terminal (40) to the charger (20). Of course, if necessary, the operating terminal (40) can also transmit the data (more specifically, the recovery data) of the data recovery reference point to the charger (20).

Accordingly, the charger (20) can extract data (e.g., recovery data) of a data recovery reference point in time from the operating terminal (40) at the time of receiving the data recovery command, and perform continuous data recovery based on the extracted data of the data recovery reference point in time.

If the time at which the above-mentioned data recovery command is received is considered the current time, then the data recovery reference time can be a past time since it is the time before the power outage.

As described above, since the charger/discharger (20) can transmit data (e.g., including measurement data, recovery data, and result data) for each channel according to the charging/discharging process to the operating terminal (40) in real time or periodically, the data recovery reference point in time can also be determined for each channel as described above. Accordingly, for example, if a battery charging/discharging process is performed on channel 1 and a power outage occurs and then power is restored, and the battery is connected to channel 2 and data recovery is desired, data recovery can be performed on channel 2 based on the recovery data at the data recovery reference point in time determined on channel 1.

As another example, there is a second event in which a user forcefully stops the first process in the middle and resumes the first process after completing the second process. In this case, the operating terminal (40) can transmit the user's forceful stop command of the first process to the charger/discharger (20) and determine a data recovery reference point in time. The operating terminal (40) transmits the data recovery reference point in time together with the data recovery command to the charger/discharger (20). Of course, if necessary, the operating terminal (40) can additionally transmit data necessary for data recovery (e.g., recovery data at the data recovery reference point in time) to the charger/discharger (20).

Here, the data recovery reference point can be automatically determined as the data recovery reference point at the time of the last data saved before the first process was forcibly stopped on the operating terminal (40) side, or can be arbitrarily determined by the user (administrator).

In the case of the second event described above, the operating terminal (40) receives and stores data (e.g., including measurement data, recovery data, and result data) from the charger (20) in real time or periodically before the second event. In this way, each time point at which data is received and stored is a unique storage time point, and the received data can be stored for each storage time point.

However, when the first process is forcibly stopped, data from the charger (20) is transmitted to the operating terminal (40) and stored at each storage point until the first process is forcibly stopped, so the operating terminal (40) can automatically determine one point in time (e.g., the storage point of the last data stored before the first process is forcibly stopped) among the multiple storage points as the data recovery reference point for the first process.

In this way, the operating terminal (40) can display the flag value of the point in time when the data recovery reference point for the first process is determined when the first process is resumed as "1". Then, the operating terminal (40) stores the determined data recovery reference point in time and transmits the data recovery reference point in time to the charger/discharger (20). Of course, if necessary, the data recovery reference point in time for the first process when the first process is resumed may be determined by a user's key input.

Accordingly, the charger/discharger (20) extracts data (e.g., recovery data) at the data recovery reference point in time for the first process from the operating terminal (40) when the first process is forcibly stopped during execution and then the second process is completed and the first process is resumed, and continuous data recovery can be performed based on the extracted data at the data recovery reference point in time.

As another example, there is a third event that performs the first process (battery 1) on the first channel and the second process (battery 2) on the second channel, forcibly stops the first process in the middle, and resumes the first process on the second channel when the second process is completed. In this case, the operating terminal (40) can transmit the user's command to forcefully stop the first process on the first channel to the charger/discharger (20) and determine a data recovery reference point in time. The operating terminal (40) transmits the data recovery reference point in time together with the data recovery command to the charger/discharger (20). Of course, if necessary, the operating terminal (40) can additionally transmit data necessary for data recovery (e.g., recovery data at the data recovery reference point in time) to the charger/discharger (20).

Here, the data recovery reference point may be automatically determined as the data recovery reference point as the last saved data storage point before the first process in the first channel is forcibly stopped on the operating terminal (40) side, or may be arbitrarily determined by the user (administrator).

In the case of the third event described above, the operating terminal (40) receives and stores data (e.g., including measurement data, recovery data, and result data) from the charger (20) in real time or periodically before the third event. In this way, each time point at which data is received and stored is a unique storage time point, and the received data can be stored for each storage time point.

However, when the first process in the first channel is forcibly stopped, the data of the first process in the first channel from the charger/discharger (20) is transmitted to the operating terminal (40) and stored for each storage time point until the first process is forcibly stopped, so the operating terminal (40) can automatically determine one of the multiple storage time points (e.g., the storage time point of the data that was last stored before the first process in the first channel was forcibly stopped) as the data recovery reference time point for the first process.

In this way, the operating terminal (40) can display the flag value of the point in time as “1” when the data recovery reference point in time for the first process is determined when the first process is resumed in the second channel. Then, the operating terminal (40) stores the determined data recovery reference point in time and transmits the data recovery reference point in time to the charger/discharger (20). Of course, if necessary, the data recovery reference point in time for the first process when the first process is resumed in the second channel may be determined by a user’s key input.

Accordingly, the charger/discharger (20) extracts data (e.g., recovery data) at a data recovery reference point in time for the first process from the operating terminal (40) when the first process is performed on the first channel, forcibly stops, completes the second process on the second channel, and then resumes the first process on the second channel, and can perform continuous data recovery based on the extracted data at the data recovery reference point in time.

For example, the operating terminal (40) may be a PC, which can be viewed as acting as a control tower.

FIG. 2 is a drawing for explaining the internal configuration of the charging/discharging system illustrated in FIG. 1, and FIG. 3 is a drawing employed to explain the storage of process data and recovery data into the operating terminal illustrated in FIG. 2.

The charger/discharger (20) of the charging/discharging system (50) of Fig. 2 may include a power supply unit (21), a communication unit (22), a storage unit (23), and a control unit (24).

The power terminal (21) is connected to the power supply (10) and can receive a predetermined input power from the power supply (10).

The communication unit (22) performs communication with the operating terminal (40).

For example, the communication unit (22) can transmit data (e.g., including measurement data, recovery data, and result data) according to the battery charging and discharging process performed in real time or periodically before a power outage to the operating terminal (40).

In addition, the communication unit (22) can receive a data recovery command and a data recovery reference point from the operating terminal (40) as power is restored after a power outage. Additionally, the communication unit (22) can receive data at the data recovery reference point from the operating terminal (40) as needed. Here, the data at the data recovery reference point can be, for example, measurement data, recovery data, and result data, and among them, it can be recovery data.

Meanwhile, if the first process is forcibly stopped while it is being performed and the first process is resumed after the second process is completed, the communication unit (22) can receive the data recovery reference point of the first process from the operating terminal (40). Of course, if necessary, the communication unit (22) can additionally receive data at the data recovery reference point of the first process from the operating terminal (40). Here, the data at the data recovery reference point can be, for example, measurement data, recovery data, and result data, and among them, it can be recovery data.

On the other hand, when performing the first process (battery 1) on the first channel and the second process (battery 2) on the second channel, and the first process is forcibly stopped in the middle and the first process is resumed on the second channel when the second process is completed, the communication unit (22) can receive the data recovery reference point of the first process on the second channel from the operating terminal (40). Of course, if necessary, the communication unit (22) can additionally receive data at the data recovery reference point of the first process on the second channel from the operating terminal (40). Here, the data at the data recovery reference point can be, for example, measurement data, recovery data, and result data, and among them, it can be recovery data.

The storage unit (23) can store data (e.g., including measurement data, recovery data, and result data) according to the performance of the battery charging/discharging process (including the battery charging/discharging process for each channel) before an event occurs in real time or periodically. At this time, the storage unit (23) can store data (e.g., including measurement data, recovery data, and result data) for each storage time by setting each time point of real time or periodic storage as a unique storage time point.

Additionally, the storage unit (23) can store the data recovery reference point from the operating terminal (40) received by the communication unit (22).

Of course, if the operating terminal (40) transmits data (particularly, recovery data) at the data recovery reference point to the charger (20) as needed, the storage unit (23) can store the data (particularly, recovery data) at the data recovery reference point together with the data recovery reference point.

The control unit (24) can control the overall operation of the charger/discharger (20).

For example, upon receiving a data recovery command from an operating terminal (40), the control unit (24) can control a data recovery operation to provide continuity of process data by allowing newly started process data to be stored from the last point of the previous process data when power is restored after a power outage, based on data (i.e., recovery data) corresponding to a data recovery reference point in time among the data previously stored in the storage unit (23).

Of course, if the charger (20) receives data (particularly, recovery data) at the data recovery reference point from the operating terminal (40), the data recovery operation for providing continuity of the process data as described above can be controlled based on the data recovery reference point stored in the storage unit (23) and the data recovery reference point from the operating terminal (40) at the data recovery reference point.

In another example, there is a case where the first process is forcibly stopped in the middle and the first process is resumed after the second process is completed. In this case, the control unit (24) can forcibly stop the first process according to a command to forcibly stop the first process from the operating terminal (40). In addition, the control unit (24) can control a data recovery operation to provide continuity of process data so that process data newly started as the first process is resumed can be stored from the last point of the previous process data based on data (i.e., recovery data) corresponding to the data recovery reference point of the first process among the data pre-stored in the storage unit (23).

Of course, if the charger (20) receives data (particularly, recovery data) from the operating terminal (40) at the data recovery reference point of the first process, the data recovery operation for providing continuity of the process data as described above can be controlled based on the data recovery reference point stored in the storage unit (23) and the data (particularly, recovery data) at the data recovery reference point of the first process from the operating terminal (40).

As another example, there is a case where, while performing a first process (battery 1) on a first channel and performing a second process (battery 2) on a second channel, the first process is forcibly stopped in the middle and, when the second process is completed, the first process is resumed on the second channel. In this case, the control unit (24) can forcibly stop the first process in accordance with a command to forcibly stop the first process on the first channel from the operating terminal (40). In addition, the control unit (24) can control a data recovery operation to provide continuity of process data so that process data newly started as the first process is resumed on the second channel can be stored continuously from the last point of the previous process data, based on data corresponding to the data recovery reference point of the first process (i.e., recovery data) among the data pre-stored in the storage unit (23).

Meanwhile, the operating terminal (40) of the charging/discharging system (50) of Fig. 2 may include a power supply unit (41), a communication unit (42), a storage unit (43), a control unit (44), a display unit (45), and an input unit (46).

The power terminal (41) is connected to the power supply (10) and can receive a predetermined input power from the power supply (10).

The communication unit (42) performs communication with the charger/discharger (20).

For example, the communication unit (42) can receive data (e.g., including measurement data, recovery data, and result data) according to the battery charging and discharging process performed in real time or periodically before a power outage from the charger/discharger (20).

In addition, the communication unit (42) can transmit a data recovery command and a data recovery reference point to the charger/discharger (20). Of course, if necessary, the communication unit (42) can additionally transmit data at the data recovery reference point to the charger/discharger (20).

Meanwhile, if the first process is forcibly stopped in the middle and the second process is completed before the first process is resumed, the communication unit (42) can transmit the data recovery reference point of the first process to the charger/discharger (20). Of course, if necessary, the communication unit (42) can additionally transmit data at the data recovery reference point of the first process to the charger/discharger (20). Here, the data at the data recovery reference point can be, for example, measurement data, recovery data, and result data, and among them, it can be recovery data.

On the other hand, when performing the first process (battery 1) on the first channel and performing the second process (battery 2) on the second channel, and the first process is forcibly stopped in the middle and the first process is resumed on the second channel when the second process is completed, the communication unit (42) can transmit the data recovery reference point of the first process on the second channel to the charger/discharger (20). Of course, if necessary, the communication unit (22) can additionally transmit the data at the data recovery reference point of the first process on the second channel to the charger/discharger (20). Here, the data at the data recovery reference point can be, for example, measurement data, recovery data, and result data, and among them, it can be recovery data.

The storage unit (43) can store data (e.g., including measurement data, recovery data, and result data) according to the performance of the battery charging/discharging process (including the battery charging/discharging process for each channel) received by the communication unit (42) in real time or periodically. At this time, the storage unit (43) can store data (e.g., including measurement data, recovery data, and result data) for each storage time by setting each storage time as a unique storage time.

That is, as illustrated in FIG. 3, the charger (20) can transmit process data and recovery data to the operating terminal (40) in real time or periodically. And, the process data and recovery data are stored separately from each other. Accordingly, the storage unit (43) can be divided into storage space 1 and storage space 2. For example, if the process data and recovery data are transmitted from the charger (20) to the operating terminal (40) at 16:00, the process data (e.g., including measurement data and result data) at the corresponding time (point in time) can be stored in storage space 1 of the storage unit (43) of the operating terminal (40), and the recovery data at the corresponding time (point in time) can be stored in storage space 2 of the storage unit (43).

In this way, in the present invention, the process data and recovery data from the charger/discharger (20) are basically transmitted to the operating terminal (40) and stored separately in the storage unit (43). Alternatively, the process data may be transmitted to the operating terminal (40) in real time, and the recovery data may be transmitted to the operating terminal (40) periodically and stored separately. Alternatively, the process data may be transmitted to the operating terminal (40) in real time, and the recovery data may be transmitted to the operating terminal (40) and stored separately whenever a specific event is generated (detection; power outage detection, user's forced stop command received).

Here, the process data may be data that is refreshed in terms of storage space utilization, and the recovery data may be data that is not refreshed but periodically accumulated.

Additionally, the storage unit (43) can store a flag value (e.g., “1”) for the data recovery reference point as determined at the data recovery reference point.

The control unit (44) can control the overall operation of the operating terminal (40).

For example, the control unit (44) can control the data recovery command of the user to be transmitted to the charger/discharger (20) after the power is restored after the power is lost, and also control the data recovery reference point to be transmitted to the charger/discharger (20). Of course, if necessary, the control unit (44) can control the data required for data recovery (e.g., recovery data at the data recovery reference point) to be transmitted to the charger/discharger (20) together with the data recovery command and the data recovery reference point.

In another example, there is a case where the first process is forcibly stopped in the middle and the second process is completed before the first process is resumed. In this case, the control unit (44) receives the user's forced stop command for the first process through the input unit (46) and transmits the forced stop command for the first process to the charger/discharger (20). Then, the control unit (44) can receive the process data and recovery data of the first process at the time of receiving the forced stop command from the charger/discharger (20) and store them in the storage unit (43) and determine a data recovery reference point in time for the first process. The control unit (44) can store the determined data recovery reference point in time for the first process in the storage unit (43) and transmit it to the charger/discharger (20).

As another example, there is a case where, while performing a first process (battery 1) on a first channel and performing a second process (battery 2) on a second channel, the first process is forcibly stopped in the middle and, when the second process is completed, the first process is resumed on the second channel. In this case, the control unit (44) receives a forced stop command for the first process on the first channel from the user through the input unit (46), and transmits the forced stop command for the first process on the first channel to the charger/discharger (20). In addition, the control unit (44) can receive process data and recovery data of the corresponding process at the time of receiving the forced stop command for the first process on the first channel from the charger/discharger (20), store them in the storage unit (43), and determine a data recovery reference time for the first process on the second channel. The control unit (44) can store the data recovery reference point for the first process in the determined second channel in the storage unit (43) and transmit it to the charger/discharger (20).

Here, the control unit (44) may include a data separation unit (44a) and a time determination unit (44b).

The data separation unit (44a) can separate data (e.g., data in the form of a file) received from the charger (20) into recovery data and non-recovery data (i.e., process data). For example, the data separation unit (44a) can separate the received data into recovery data and non-recovery data by parsing the data.

In other words, the data separation unit (44a) can separate the recovery data used in data recovery from other data among the data sets received from the charger/discharger (20).

The data separation unit (44a) can store separated recovery data and non-recovery data (e.g., measurement data, result data) in the storage unit (43).

The point-in-time determination unit (44b) can determine the data recovery reference point in time required for data recovery according to the occurrence of an event.

For example, there is a case where power is restored after a power outage. In this case, the time point determination unit (44b) determines the data recovery reference point required for data recovery as the power is restored after the power outage. In this case, the data recovery reference point may be a data recovery reference point arbitrarily determined by a user (administrator) as described above, or one of the storage points (e.g., the point immediately before the power outage) among the storage points of data stored in the storage unit (43) may be automatically determined as the data recovery reference point.

At this time, the time point determination unit (44b) can display the flag value for the time point as “1” when the data recovery reference time point is determined.

As another example, there is a case where the first process is forcibly stopped in the middle and the second process is completed before the first process is resumed. In this case, the time point determination unit (44b) can determine the time point at which the forced stop command is received (e.g., the time point at which the last data was saved before the first process was forcibly stopped) as the data recovery reference time point. Of course, if necessary, a time point arbitrarily determined by a user (administrator) (i.e., a time point determined from among the storage times at which the recovery data is saved in the storage unit (43)) can be determined as the data recovery reference time point.

As another example, there is a case where, while performing the first process (battery 1) on the first channel and performing the second process (battery 2) on the second channel, the first process is forcibly stopped in the middle and, when the second process is completed, the first process is resumed on the second channel. In this case, the time point determination unit (44b) can determine the time point at which the forced stop command is received (e.g., the time point at which the last stored data was saved before the first process on the first channel was forcibly stopped) as the data recovery reference time point. Of course, if necessary, the time point arbitrarily determined by the user (administrator) (i.e., the time point determined from among the storage times at which the recovery data is stored in the storage unit (43)) can be determined as the data recovery reference time point.

The display unit (45) can display data from the charger/discharger (20) prior to power outage received from the communication unit (42) in real time.

In addition, the display unit (45) can display data for each storage time stored in the storage unit (43) as each event occurs.

For example, in the case of the first event where the power is restored after the power is lost, the display unit (45) can display the data stored in the storage unit (43) according to the storage time (i.e., data before the power is lost) as the power is restored after the power is lost. This is to enable the user to determine one of the multiple storage time points as the data recovery reference time point.

As another example, in the case of a second event in which a user forcefully stops a first process in the middle and resumes the first process after completing the second process, the display unit (45) can display data of the first process stored in the storage unit (43) according to the storage time point (i.e., data before the first process was forcefully stopped) as the first process was forcefully stopped in the middle. This is to enable the user to determine one of the multiple storage time points as the data recovery reference time point of the first process.

As another example, in the case of a third event that performs a first process (battery 1) on a first channel and a second process (battery 2) on a second channel, forcibly stops the first process in the middle, and restarts the first process in the second channel when the second process is completed, the display unit (45) can display on the screen the data of the first process in the first channel stored in the storage unit (43) according to the storage time point (i.e., data before the first process was forcibly stopped) as the first process in the first channel is forcibly stopped. This is to enable the user to determine one of the multiple storage time points as the data recovery reference time point of the first process in the first channel.

The input unit (46) can input a data recovery command for each event.

For example, in the case of the first event of a power outage and then power recovery, the input unit (46) can input a data recovery command as the power is restored after the power outage. In this case, the user can input the data recovery command by operating the input unit (46).

As another example, if the second event is one in which the user forces the first process to stop in the middle and resumes the first process after the second process is completed, the input unit (46) can input a data recovery command between the time the second process is completed and the time the first process is resumed. In this case, the user can input the data recovery command by operating the input unit (46).

As another example, in the case of a third event that performs a first process (battery 1) on a first channel and a second process (battery 2) on a second channel, forcibly stops the first process in the middle, and resumes the first process on the second channel when the second process is completed, the input unit (46) can input a data recovery command between the time when the second process on the second channel is completed and the first process on the second channel is resumed. In this case, the user can input the data recovery command by operating the input unit (46).

In addition, the input unit (46) can input a data recovery reference point. In this case, the user can check multiple data points for each storage point on the display unit (45) and operate the input unit (46) to determine one storage point as the data recovery reference point, thereby inputting the corresponding data recovery reference point.

Of course, unlike the above, it has already been explained that the data recovery reference point can be automatically determined by the operating terminal (40) rather than being selected by the user.

FIG. 4 is a diagram schematically illustrating a data recovery operation in the charging/discharging system of the present invention.

The charger (20) measures various situations in progress during the process in real time or periodically before the above-described event occurs, creates recovery data using the measured measurement data, and creates result data using the recovery data.

And, the charger (20) transmits measurement data, recovery data, and result data generated in real time or periodically to the operating terminal (40).

Here, the measurement data may include various raw data, such as current, voltage, and power (W) measured in real time in the charging step, and current, voltage, and power (W) measured in real time in the discharging step. It is obvious that the measurement data is not limited to the examples described above, but may be more diverse.

That is, measurement data can be understood as data that includes one or more raw data measured in real time or periodically during process execution.

The result data may include accumulated current (IntegralAmpareHour), accumulated power (InterralWattHour), current of the charge step (chargeAmpareHour), power of the charge step (chargeWattHour), current of the discharge step (dischargeAmpareHour), and power of the discharge step (dischargeWattHour). The accumulated current can refer to an accumulated value calculated by measuring the current in real time at each charge/discharge step from the start of the process to the end. For example, the accumulated current can be obtained as "IntegralAmpareHour = seedintegralCapacity + (sumintegralCapacity / (3600 * equipment cycle))". The accumulated power can refer to an accumulated value calculated by measuring the power with the voltage and current measured in real time at each charge/discharge step from the start of the process to the end. For example, the accumulated power amount can be obtained as "IntegralWattHour = seedintegralWattHour + (sumintegralWattHour /(3600 * equipment cycle))". The current amount of the charging step can mean the current amount calculated with the current measured in real time in the charging step. For example, the current amount of the charging step can be obtained as "ChargeAmpareHour = seedChargeAmpreHour + (sumChargeAmpreHour /(3600 * equipment cycle))". The power amount of the charging step can mean the power amount calculated with the voltage and current measured in real time in the charging step. For example, the power amount of the charging step can be obtained as "ChargeWattHour = seedChargeWattHour + (sumChargeWattHour /(3600 * equipment cycle))". The current amount of the discharging step can mean the current amount calculated with the current measured in real time in the discharging step. For example, the current amount of the discharge step can be obtained as "DischargeAmpareHour = seedDischargeAmpareHour + (sumDischargeAmpareHour /(3600 * equipment cycle))". The power amount of the discharge step can mean the power amount calculated with the voltage and current measured in real time in the discharge step. For example, the power amount of the discharge step can be obtained as "DischargeWattHour = seedDischargeWattHour + (sumDischargeWattHour /(3600 * equipment cycle))". It is obvious that the result data is not limited to the examples described above and can be more diverse. For example, additional result data can include a capacity value calculated with the voltage and current measured in real time, a power value calculated with the voltage and current measured in real time, and a power amount calculated with the voltage and current measured in real time.

That is, the result data can be understood as data that includes the current point-in-time result (e.g., a predetermined value) created by processing measurement data or recovery data.

The recovery data may include additional values for calculating accumulated Ah (seedintegralCapacity), real-time accumulated current (sumintegralCapacity), additional values for calculating Ah of the charge step (seedChargeAmpareHour), real-time accumulated current in the charge step (sumChargeAmpareHour), additional values for calculating Ah of the discharge step (seedDischargeAmpareHour), real-time accumulated current in the discharge step (sumDischargeAmpareHour), additional values for calculating accumulated Wh (seedintegralWattHour), real-time accumulated W value (sumintegralWattHour), additional values for calculating Wh of the charge step (seedchargeWattHour), real-time accumulated W value in the charge step (sumchargeWattHour), additional values for calculating Wh of the discharge step (seedDischargeWattHour), and real-time accumulated W value in the discharge step (sumDischargeWattHour). Here, the additional value (seedintegralCapacity) for calculating the accumulated Ah can mean a value that stores the current accumulated Ah value when the sumintegralCapacity variable becomes 90% of the allowable value. The current value (sumintegralCapacity) accumulated in real time can mean a value that accumulates the current value measured for each equipment cycle in the charge and discharge steps. The additional value (seedChargeAmpareHour) for calculating the Ah of the charge step can mean a value that stores the current charge Ah value when the sumChargeAmpareHour variable becomes 90% of the allowable value. The current value (sumChargeAmpareHour) accumulated in real time in the charge step can mean a value that accumulates the current value measured for each equipment cycle in the charge step. The additional value (seedDischargeAmpareHour) for calculating the Ah of the discharge step can mean a value that stores the current discharge Ah value when the sumDischargeAmpareHour variable becomes 90% of the allowable value. The current value accumulated in real time in the discharge step (sumDischargeAmpareHour) can mean the accumulated value of the current value measured for each equipment cycle in the discharge step. The additional value for calculating the accumulated Wh (seedintegralWattHour) can mean the value that stores the current accumulated Wh value when the sumintegralWattHour variable becomes 90% of the allowable value. The W value accumulated in real time (sumintegralWattHour) can mean the accumulated value of the W value calculated with the current and voltage measured for each equipment cycle in the charge and discharge steps. The additional value for calculating Wh in the charge step (seedchargeWattHour) can mean the value that stores the current charge Wh value when the sumChargeWattHour variable becomes 90% of the allowable value. The W value accumulated in real time in the charge step (sumchargeWattHour) can mean the accumulated value of the W value calculated with the current and voltage measured for each equipment cycle in the charge step. The additional value (seedDischargeWattHour) for calculating Wh of the discharge step can mean the value that stores the current discharge Wh value when the sumDischargeWattHour variable becomes 90% of the allowable value. The W value (sumDischargeWattHour) accumulated in real time in the discharge step can mean the accumulated value of the W value calculated by the current and voltage measured for each equipment cycle in the discharge step. It is obvious that the recovery data is not limited to the above-mentioned examples and can be more diverse.

That is, recovery data can be understood as data that includes the result (e.g., a predetermined value) created by processing measurement data.

Meanwhile, if any of the events described above occurs, the charger (20) must perform data recovery based on previous data to ensure data continuity.

However, in the past, when measurement data, recovery data, and result data were exchanged in real time between the charger (20) and the operating terminal (40), it was not possible to store all of them due to capacity limitations. Accordingly, in the past, recovery data was not stored, and was only used to obtain result data. Only measurement data and result data were displayed on the display unit (45) of the operating terminal (40), and recovery data was not displayed on the screen.

Therefore, as previously described, when power was restored after a power outage, or when a user forcibly stopped the first process midway and resumed the first process after completing the second process, or when the first process (battery 1) was performed on the first channel and the second process (battery 2) was performed on the second channel, and when the first process was forcibly stopped midway and the first process was resumed on the second channel after the second process was completed, the previous data could not be utilized to generate the result data at the current point in time, and thus data continuity could not be provided.

Accordingly, in the embodiment of the present invention, the charger/discharger (20) and the operating terminal (40) are enabled to exchange measurement data, recovery data, and result data.

Accordingly, in the embodiment of the present invention, when power is restored after a power outage, the charger/discharger (20) can generate current point-in-time recovery data by combining the recovery data before the power outage (i.e., recovery data at the data recovery reference point in time determined by the user or the operating terminal (40)) and the measurement data at the current point in time after the power restoration (i.e., the point in time when the data recovery command is received). In addition, the charger/discharger (20) can generate current point-in-time result data by using the generated current point-in-time recovery data.

In this way, when the power of the charger/discharger (20) is completely cut off and then restored, data continuity can be provided so that newly started process data can be stored from the last point of the previous process data.

Meanwhile, if a user forcibly stops the first process in the middle and resumes the first process after completing the second process, the charger/discharger (20) can generate recovery data at the current point in time by combining the recovery data at the time of the last data storage (i.e., the data recovery reference time) before the first process was forcibly stopped and the measurement data at the current point in time when the first process is resumed. In addition, the charger/discharger (20) can generate result data at the current point in time by using the generated recovery data at the current point in time.

In this way, even if the first process is forcibly stopped in the middle and the second process is completed before the first process is resumed, data continuity can be provided so that the newly started process data can be stored from the last point of the previous process data.

On the other hand, when performing the first process (battery 1) on the first channel and performing the second process (battery 2) on the second channel, and the first process is forcibly stopped in the middle and the first process is resumed on the second channel when the second process is completed, the charger/discharger (20) can generate the recovery data of the current point in time by combining the recovery data of the storage time of the data last saved before the first process on the first channel was forcibly stopped (i.e., the data recovery reference time) with the measurement data of the current point in time when the first process is resumed on the second channel. In addition, the charger/discharger (20) can generate the result data of the current point in time by using the generated recovery data of the current point in time.

In this way, even if the first process is forcibly stopped in the middle of the first channel and the second process is completed in the second channel, and then the first process is resumed in the second channel, data continuity can be provided so that the newly started process data can be stored from the last point of the previous process data.

FIG. 5 is a flowchart for explaining a data recovery method according to the first embodiment of the present invention, and FIG. 6 is a drawing employed in the explanation of FIG. 5.

First, the data recovery method according to the first embodiment of the present invention can be applied in a case where data recovery is performed when power is restored after a power outage occurs while the charger/discharger (20) is performing a battery charging/discharging process for a predetermined period of time, as illustrated in FIG. 6.

That is, before a power outage occurs, the charger/discharger (20) stores real-time or periodically recovery data and process data (e.g., measurement data, result data) in the storage unit (23) and transmits them to the operating terminal (40). The operating terminal (40) stores real-time or periodically received recovery data and process data (e.g., measurement data, result data) in the storage unit (43). Although the data exchange process between the charger/discharger (20) and the operating terminal (40) is not illustrated in FIG. 5, those working in the same industry will be able to sufficiently understand it with the above-described explanation.

In this state, after the power is restored following a power outage, the operating terminal (40) displays the data stored in the storage unit (43) at each storage time (i.e., data before the power outage) on the display unit (45).

Accordingly, the user (administrator) can input one of the multiple storage points as the data recovery reference point (A). The operating terminal (40) determines the corresponding storage point as the data recovery reference point (A) according to the key input (S10). In this case, the operating terminal (40) can store the determined data recovery reference point (A) in the storage unit (43) with the flag value set to "1".

Then, the user inputs a data recovery command by manipulating the input unit (46). Accordingly, the operating terminal (40) receives the user's data recovery command (B) (S12).

Next, the operating terminal (40) transmits the data recovery reference point (A) and the data recovery command (B) to the charger (20) (S14). Of course, if necessary, the operating terminal (40) may additionally transmit data (particularly, recovery data) at the data recovery reference point (A).

Thereafter, the charger (20) combines the measurement data at the current time point when the data recovery command (B) is received and the recovery data corresponding to the data recovery reference time point (A) from the operating terminal (40) among the data stored in the storage unit (23) to generate the recovery data at the current time point when the data recovery command (B) is received (S16). Of course, if the data (particularly, the recovery data) at the data recovery reference time point (A) is additionally received from the operating terminal (40), the measurement data at the current time point when the data recovery command (B) is received and the data (particularly, the recovery data) at the data recovery reference time point (A) from the operating terminal (40) can be combined to generate the recovery data at the current time point when the data recovery command (B) is received.

Then, the charger/discharger (20) generates the result data of the current time point that received the data recovery command (B) using the recovery data of the current time point that was generated (S18). Of course, the charger/discharger (20) will store the measurement data, recovery data, and result data of the current time point that were generated in this way in the storage unit (23). As a result, when the power of the charger/discharger (20) is completely cut off and then restored, it is possible to provide data continuity that allows newly started process data to be stored from the last point of the previous process data.

Next, the charger (20) transmits the measurement data, recovery data, and result data of the current point in time to the operating terminal (40) (S20).

Accordingly, the operating terminal (40) stores the received current measurement data, recovery data, and result data in the storage unit (43) (S22).

Thereafter, the charger (20) periodically (in real time) generates measurement data, recovery data, and result data after receiving the data recovery command (B) and transmits them to the operating terminal (40) (S24).

The operating terminal (40) stores measurement data, recovery data, and result data received periodically (in real time) after receiving a data recovery command (B) in the storage unit (43) (S26).

FIG. 7 is a flowchart for explaining a data recovery method according to the second embodiment of the present invention, and FIG. 8 is a drawing employed in the explanation of FIG. 7.

First, the data recovery method according to the second embodiment of the present invention can be applied when, as illustrated in FIG. 8, the charger/discharger (20) is performing the first process, the first process is forcibly stopped in the middle, and the first process is resumed after the second process is completed. This is to increase the efficiency of the process. In other words, when a test that needs to be processed urgently intervenes before the first process is completed, the first process is forcibly stopped, the test is quickly performed as the second process, and then the first process is resumed, so that the efficiency of the process can be increased.

The charger (20) performs the first process according to the process schedule (S50).

The charger (20) stores process data and recovery data in real time or periodically in the storage unit (23) according to the first process, and then transmits the process data and recovery data to the operating terminal (40) in real time or periodically (S52).

Accordingly, the operating terminal (40) stores recovery data and process data (e.g., measurement data, result data) received in real time or periodically in the storage unit (43) (S54).

In this state, when the operating terminal (40) receives a forced stop command from the user through the input unit (46) (“Yes” in S56), the operating terminal (40) transmits the forced stop command to the charger (20).

Upon receiving a forced stop command, the charger (20) stores the process data and recovery data of the first process at the current time when the forced stop command was received (e.g., the time of saving the last saved data before the first process was forced to stop) in the storage unit (23) and then transmits the process data and recovery data to the operating terminal (40) (S58).

The operating terminal (40) determines the data recovery reference point based on the current point in time when the forced stop command is received. More specifically, the operating terminal (40) may automatically determine the data recovery reference point as the last data storage point before the first process is forced to stop, or the user (administrator) may arbitrarily determine it. When the data recovery reference point is determined in this way, the operating terminal (40) stores the corresponding data recovery reference point in the storage unit (43) (S60). Of course, the operating terminal (40) transmits the stored data recovery reference point to the charger (20). If necessary, the operating terminal (40) may additionally transmit the data (particularly, the recovery data) that was stored at the data recovery reference point.

Afterwards, the charger/discharger (20) forces the first process currently being performed to stop according to the forced stop command (S62).

Accordingly, the charger (20) performs and completes the second process after the forced stop of the first process (S64).

In this way, when the second process is completed, the charger/discharger (20) resumes the first process that was forcibly stopped in response to the data recovery command from the operating terminal (40) (S66). In this case, in response to the user's data recovery command from the operating terminal (40), the recovery data corresponding to the data recovery reference point in time of the first process and the measurement data at the current point in time when the first process is resumed are combined to generate the recovery data at the current point in time. Of course, if the recovery data at the data recovery reference point in time is additionally received from the operating terminal (40), the measurement data at the current point in time when the first process is resumed and the recovery data at the data recovery reference point in time from the operating terminal (40) can be combined to generate the recovery data at the current point in time. Then, the charger/discharger (20) generates the result data at the current point in time using the generated recovery data at the current point in time. Of course, the charger/discharger (20) will store the measurement data, recovery data, and result data at the current point in time generated in this way in the storage unit (23).

Accordingly, the charger/discharger (20) can provide data continuity that allows newly started process data to be stored from the last point of the previous process data even when the first process is forcibly stopped midway during the first process and the first process is resumed after the second process is completed.

FIG. 9 is a flowchart for explaining a data recovery method according to the third embodiment of the present invention, and FIG. 10 is a drawing employed in the explanation of FIG. 9.

First, the data recovery method according to the third embodiment of the present invention can be applied when, as illustrated in FIG. 10, the charger/discharger (20) performs the first process (battery 1) on the first channel (CH1) and the second process (battery 2) on the second channel (CH2), the first process is forcibly stopped in the middle, and the first process is restarted on the second channel (CH2) after the second process of the second channel (CH2) is completed. This is to restart the first process on a channel without a problem (e.g., the second channel (CH2)) when a problem occurs on the first channel (CH1) while performing the first process on the first channel (CH1). If a problem occurred on the first channel (CH1), the first channel (CH1) had to wait until the repair was completed, but if the first process is restarted on a channel without a problem, there is no need to wait until the repair is completed.

The charger/discharger (20) performs the first process (battery 1) on the first channel (CH1) and the second process (battery 2) on the second channel (CH2) according to the process schedule (S70).

The charger (20) stores process data and recovery data for each channel in real time or periodically in the storage unit (23) as the process is performed for each channel, and then transmits the process data and recovery data for each channel to the operating terminal (40) in real time or periodically (S72).

Accordingly, the operating terminal (40) stores recovery data and process data (e.g., measurement data, result data) for each channel received in real time or periodically in the storage unit (43) (S74).

In this state, when the operating terminal (40) receives a forced stop command for the first process of the user's first channel (CH1) through the input unit (46) (“Yes” in S76), the operating terminal (40) transmits the forced stop command to the charger (20).

Upon receiving a forced stop command, the charger (20) stores the process data and recovery data of the first process in the first channel at the current time when the forced stop command was received (e.g., the time of saving the last saved data before the first process was forced to stop) in the storage unit (23) and then transmits the process data and recovery data to the operating terminal (40) (S78).

The operating terminal (40) determines the data recovery reference point based on the current point in time when the forced stop command is received. More specifically, the operating terminal (40) may automatically determine the data recovery reference point as the last saved data storage point before the first process of the first channel (CH1) is forced to stop, or the user (administrator) may arbitrarily determine it. When the data recovery reference point is determined in this way, the operating terminal (40) stores the corresponding data recovery reference point in the storage unit (43) (S80). Of course, the operating terminal (40) transmits the stored data recovery reference point to the charger (20). If necessary, the operating terminal (40) may additionally transmit the data (particularly, the recovery data) that was stored at the data recovery reference point.

Afterwards, the charger/discharger (20) forces the first process of the first channel (CH1) currently being performed to stop according to the forced stop command (S82).

Accordingly, when the charger/discharger (20) completes the second process in the second channel (CH2) (S84), it resumes the first process, which was forcibly stopped, in the second channel (CH2) in response to the data recovery command from the operating terminal (40) (S86). In this case, in response to the user's data recovery command from the operating terminal (40), the recovery data corresponding to the data recovery reference point in time of the first process and the measurement data at the current point in time when the first process is resumed in the second channel (CH2) are combined to generate the recovery data at the current point in time. Of course, if the recovery data at the data recovery reference point in time is additionally received from the operating terminal (40), the recovery data at the current point in time can be generated by combining the measurement data at the current point in time when the first process is resumed and the recovery data at the data recovery reference point in time from the operating terminal (40). Then, the charger/discharger (20) generates the result data at the current point in time using the generated recovery data at the current point in time. Of course, the charger (20) will store the measurement data, recovery data and result data generated at the current point in time in the storage unit (23).

Accordingly, the charger/discharger (20) can provide data continuity so that newly started process data can be stored from the last point of the previous process data even when the first process is forcibly stopped in the middle while the first process (battery 1) is performed on the first channel (CH1) and the second process (battery 2) is performed on the second channel (CH2) and then the first process is resumed on the second channel (CH2) after the second process on the second channel (CH2) is completed.

In addition, the data recovery method of the present invention described above can be implemented as a computer-readable code on a computer-readable recording medium. The computer-readable recording medium includes all kinds of recording devices that store data that can be read by a computer system. Examples of the computer-readable recording medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc. In addition, the computer-readable recording medium can be distributed to computer systems connected to a network, so that the computer-readable code can be stored and executed in a distributed manner. In addition, functional programs, codes, and code segments for implementing the above method can be easily inferred by programmers in the technical field to which the present invention belongs.
