Description

The present disclosure relates to a control device, a control system, a control method, and a program.

Patent document 1 discloses supplying (selling) electricity stored in an electric vehicle (also called an EV) to the power grid.

JP 2016-123270 A

Being able to supply the electric power stored in the battery of an EV to the power grid (power grid) as described in Patent Document 1 is advantageous not only to the user of the EV but also to the business operator that manages the power grid. EV users can benefit financially by supplying excess power to the power grid. By receiving power from users when there is a power shortage, businesses can reduce the amount of power they purchase from other businesses.

Incidentally, power is supplied from an EV to the power grid only when the EV and the power grid are electrically connected. Businesses want to know in advance how much power can be secured. However, because EV users connect to the power grid at different times, it has been difficult to grasp the amount of power that can be secured.

The present disclosure aims to encourage users to connect an EV or the like to a control device that controls charging and discharging of a battery of an electric vehicle such as an EV.

The present disclosure relates to a control device that controls charging and discharging of a battery of an electric vehicle that can move using electric power, the battery having a running storage capacity that stores the electric power used to move the electric vehicle and a shared storage capacity for receiving and sending electric power to a power grid, and when the electric vehicle and the control device are connected so that they can be charged and discharged at a specific time, the control device transmits a connection signal indicating that the electric vehicle and the control device are connected so that they can be charged and discharged to a server that notifies a communication terminal of a user of the electric vehicle before the specific time, asking whether or not to connect the electric vehicle to the control device at the specific time.

According to the present disclosure, it is possible to prompt a user to connect an electric vehicle such as an EV to a control device that controls charging and discharging of the battery of the electric vehicle before a specific time.

The following describes an embodiment of the present invention with reference to the drawings. For the sake of convenience, the dimensions of each component shown in the drawings may differ from the actual dimensions of each component.

FIG. 1 is a schematic diagram of a power supply system 1 according to this embodiment. As shown in FIG. 1, the power supply system 1 includes a power grid (power system) 2. As shown in FIG. The power network 2 is operated, for example, by a business that uses the power supply system 1. The power grid 2 supplies electricity generated by a power generation facility 3 etc. to a house 4a, a power supply station 4b, etc., or receives electricity from a user of an electric vehicle (hereinafter referred to as an EV5), which will be described later, from a mobile battery of the EV5 ( (hereinafter referred to as a "battery"). The house 4a and the power supply station 4b are provided with a control device 6 that controls charging and discharging of the battery of the EV5. The control device 6 is provided with a power port for electrically connecting the EV5. When the user connects the EV 5 to the power port 6a of the control device 6, the EV 5 can be charged or discharged from the EV 5 to the power grid 2, and can be compensated by the business operator or the like. The control device 6 is provided with a communication device 6b for communicating with a server 7, which will be described later. Note that a control system is constructed by the communication device 6b of the control device 6 and the server 7.

EV5 runs by converting the electricity stored in the battery of EV5 into power. The battery of EV5 of a user who has signed a contract with the power supply system 1 has a storage capacity for driving and a shared storage capacity. The electricity stored in the storage capacity for driving (an example of a storage capacity for mobility) is used for driving EV5. The electricity stored in the shared storage capacity is not usually used for driving EV5, but is sent to the power grid 2 via the control device 6 when the user connects EV5 to the control device 6 during a time period (an example of a specific time) when the operator wants to secure a larger amount of electricity. At this time, connection information including identification information of EV5 and the like is sent from the control device 6 to the server 7. The connection information indicates to the control device 6 that EV5 is electrically connected in a state in which it can be discharged or charged.

The running power storage capacity and the shared power storage capacity may each constitute separate batteries, or may be determined in proportions in one battery. Further, while the EV5 is running, if the electric power in the electric storage capacity for driving is likely to be insufficient, electric power in the shared battery may be used. The shared power storage capacity may differ depending on the vehicle type or the contract, or may be the same shared power storage capacity regardless of the vehicle type or the like.

The power supply system 1 includes a server 7. The server 7 is connected to the control device 6 so that it can communicate with the control device 6. The server 7 can output a signal to the control device 6 to instruct charging the EV 5 and discharging the EV 5.

FIG. 2 is a diagram showing a server and each database in this embodiment. As shown in FIG. 2, the server 7 is connected to a fee schedule database 11. Thereby, the server 7 can obtain future electricity rates that change depending on the time zone in the wholesale power market.

The server 7 is connected to the EV identification database 12. When the server 7 receives, from the control device 6, identification information relating to the EV 5 connected to the control device 6, the server 7 can compare the identification information relating to the EV 5 with the EV identification database 12. Note that the identification information relating to the EV is information for identifying the EV 5 itself, or information for identifying the battery of the EV 5.

The server 7 is connected to a connection information database 14. The server 7 records connection information in the connection information database 14 when the EV 5 and the control device 6 are connected during a high price time (an example of a specific time) to be described later.

Figure 3 shows an example of a fee schedule. Note that the dashed line in Figure 3 indicates a threshold for determining high-price hours, which will be described later. As shown in Figure 3, electricity rates vary depending on the time of day. A time period in which the electricity rate exceeds the threshold (a time period indicated by a double-headed arrow in Figure 3) is called a high-price hour. In this embodiment, a high-price hour is an example of a specific time period.

Note that the specific time does not need to be a high price time. The specific time may be, for example, a time period when demand is increasing, or may be a completely different time determined by the convenience of business operator A.

Generally, electricity rates tend to be high during times when the demand for electricity is high, such as in the morning before the user goes to work or in the evening after the user returns home. Conversely, power rates tend to be low during times when the demand for electricity is low, such as during the day when users are out and about, or late at night when users are sleeping.

It is conceivable that business operators would prepare power generation facilities capable of meeting the highest demand for electricity, but it is not rational to set up power generation facilities or purchase electricity from other (electricity) business operators just to meet the high demand for electricity at specific times in the morning or evening. Therefore, in this embodiment, electricity stored in EV5 is used during times of high demand for electricity. At this time, it is also desirable for business operators to know in advance how much electricity they are likely to be able to receive from EV5.

However, for EV users, high-priced hours are also times when they are active, so they do not necessarily connect their EVs to the control device during high-priced hours. Therefore, in this embodiment, a suitable incentive is given to the user in order to have the user take the trouble to connect the EV 5 to the control device 6 during high-priced hours.

In the power supply system 1 of this embodiment, when the EV 5 and the power port 6a of the control device 6 are connected at a specific time, the communication device 6b of the control device 6 outputs a connection signal to the server 7. It is composed of Since this connection signal includes identification information regarding the EV 5, it is possible to identify the user of the EV 5 with which the electric vehicle (EV 5) and the power grid 2 were electrically connected at a specific time. Furthermore, the business operator can reward the user, such as points, for receiving the provision of products or services based on the connection information.

For businesses, this provides an incentive for users to connect EVs 5 to the power port 6a of the control device 6 during high price times, thereby reducing costs associated with investment in new power generation facilities 3 and purchasing electricity. In addition, businesses can estimate the amount of electricity that can be secured based on the connection information, making it easier to predict the amount of electricity that can be supplied by the power grid 2. For users, in addition to being able to receive rewards, it is expected that increases in electricity rates will be reduced by reducing the costs associated with business operators' investment in power generation facilities 3 and purchasing electricity.

Next, specific operation of the power supply system 1 will be explained.

(1) Flow before the high price hour Fig. 4 is a flow chart showing the processing performed by the server 7 before the high price hour in this embodiment. The server 7 receives the fee schedule from the fee schedule database 11 (step S1). Upon receiving the fee schedule, the server 7 judges whether there is a time period during which the electricity fee exceeds the threshold, and if so, identifies the time period during which the electricity fee exceeds the threshold as the high price hour for electricity (step S2). It is preferable that step S1 is performed several hours before the electricity fee is expected to start exceeding the threshold. For example, step S1 is performed at midnight.

Next, the server 7 determines whether the current time is longer than a predetermined time until the start of the high price period (step S3). The predetermined time may be set as appropriate depending on the convenience of the business operator or the user. In this embodiment, a case where the predetermined time is three hours is exemplified. If the current time is three hours or more before the start of the high-priced time (No in step S3), the server 7 repeats step S3 until the current time is within three hours of the start of the high-priced time.

If it is determined that the current time is within 3 hours of the start of the high price time (Yes in step S3), the server 7 notifies the user's communication terminal of the start time and end time of the high price time, and During the price period, a notification (request notification) requesting that the EV 5 be connected to the control device 6 so as to be capable of discharging and receiving electricity is transmitted (step S4). For example, the server 7 transmits the above notification to the user's communication terminal. The user who has received the notification can reply from a communication terminal or the like as to whether or not to respond to the notification request. Communication terminals include smartphones, smart watches, mobile phones, and the like.

After a predetermined period of time (for example, 30 minutes to 2 hours and 30 minutes) has elapsed since the server 7 gave the notification, the server 7 determines for each user whether or not a response to the notification has been received (step S5). Responses from the users are recorded in the notification response database 13 (see FIG. 2) connected to the server 7. If the server 7 does not receive a response from the user (No in step S5), the server 7 records unanswered information indicating that there was no response in the notification response database 13 (step S6).

When a response is obtained from the user (Yes in step S5), the server 7 judges whether the user agrees to connect the EV 5 to the power port 6a of the control device 6 for charging and discharging during the high-price time (step S7). When the user agrees to the notification (Yes in step S7), the server 7 records the consent information in the notification response database 13 (step S8). When the user rejects the notification (No in step S7), the server 7 records the rejection information in the notification response database 13 (step S9).

In addition, consenting to a connection that allows charging and discharging is treated as consenting to discharging from the EV5. In addition, not consenting to a connection that allows charging and discharging is treated as not consenting to discharging from the EV5. In addition, the server 7 may determine whether or not the user has consented to discharging by sending a notification requesting discharging separately from the notification requesting connection.

After recording in the notification response database 13, the server 7 calculates the total shared storage capacity of all EVs 5 that will be connected to the power port 6a of each control device 6 during the high price time from the EV identification database 12 and the notification response database 13 (step S10). The time when the server 7 calculates the total shared storage capacity is, for example, 30 minutes before the start of the high price time. For example, the server 7 calculates the sum of the shared storage capacity only for EVs 5 that have recorded consent information. In addition, if the percentage of EVs that consented users connected to the power port 6a of the control device 6 during the high price time as answered, and the percentage of EVs that users who recorded non-answer information connected to the control device 6 during the high price time are known, the server 7 may use the percentage to calculate the total shared storage capacity.

In this way, by the server 7 notifying the user of the EV 5 in advance at a time before the high price time, it becomes easier to encourage the user of the EV 5 to connect the EV 5 to the power grid 2 so that charging and discharging are possible (discharging or charging is possible) at a specific time. In addition, it becomes easier for the business operator to predict the amount of electricity that can be supplied from the EV 5 during the high price time.

(2) Flow during high price hours Fig. 5 is a flowchart showing the processing performed by the server 7 during the high price hours. Fig. 6 is a flowchart showing the processing performed by the power port 6a of the control device 6 during the high price hours. During the high price hours, the server 7 and the communication device 6b of the control device 6 communicate with each other as appropriate.

When the high price time starts, the communication device 6b of the control device 6 acquires identification information on the EV 5 from the EV 5 connected so that it can be charged or discharged, and transmits this identification information together with the connection information to the server 7 (step S21). Note that the power port 6a of the control device 6, rather than the communication device 6b of the control device 6, may acquire the identification information on the EV 5 from the EV 5 connected so that it can be charged or discharged. When the server 7 receives the identification information on the EV 5 from the communication device 6b of the control device 6 (step S11), it refers to the notification response database 13 and judges whether the EV 5 belongs to a user who has sent consent information in response to the notification (step S12). When the server 7 judges that the EV 5 belongs to a user who has already sent consent information, it records in the connection information database 14 that the EV 5 was connected to the control device 6 during the high price time (step S13).

Next, the server 7 refers to the EV identification database 12 to identify the shared storage capacity of the EV 5 (step S14). Once the shared storage capacity of the EV 5 has been identified, the server 7 transmits information about the shared storage capacity for the EV 5 to the communication device 6b of the control device 6 (step S15). As a result, as shown in FIG. 6, when the power port 6a of the control device 6 receives information about the shared storage capacity for the EV 5 (step S22), it acquires data on the remaining battery capacity of the EV 5 from the EV 5 and determines whether the remaining battery capacity is equal to or greater than the shared storage capacity (step S23).

If the remaining battery capacity is less than or equal to the shared storage capacity (No in step S23), the communication device 6b of the control device 6 transmits a discharge prohibition signal to the server 7 (step S27). When the server 7 receives the disable discharge signal (step S18), it records non-completion information about the EV 5 in the connection information database 14 (step S19).

If the remaining battery capacity is equal to or greater than the shared storage capacity (Yes in step S23), the communication device 6b of the control device 6 transmits a discharge enable signal to the server 7 (step S24). When the server 7 receives the discharge enable signal (step S16), if discharge from the EV 5 to the power grid 2 is required, it transmits a power reception signal to the communication device 6b of the control device 6 (step S17). When the communication device 6b of the control device 6 receives the power reception signal (step S25), the power port 6a of the control device 6 receives (discharges) power from the EV 5 based on the power reception signal from the communication device 6b and controls it to supply power to the power grid 2 (step S26).

In this way, before receiving power, the power port 6a of the control device 6 determines whether the remaining capacity of the battery is greater than or equal to the shared electricity storage capacity, and determines whether the remaining capacity of the battery is greater than or equal to the shared electricity storage capacity. In this case, the communication device 6b transmits a discharge enable signal to the server 7 based on the determination result of the power port 6a. Note that instead of the power port 6a of the control device 6, the communication device 6b may determine whether the remaining capacity of the battery is equal to or greater than the shared storage capacity. Even if the user connects the EV5 to the power port 6a of the control device 6, if the remaining battery capacity is less than the shared storage capacity, the operator can receive power from the EV5 predicted in advance. This is not desirable because the amount of power and the amount of power that can actually be supplied are different. The server 7 prompts that the remaining capacity of the battery is equal to or greater than the shared storage capacity, thereby making it easier for the business operator to predict the amount of power that can be supplied from the EV5.

Furthermore, as in this embodiment, the EV 5 is discharged to the power grid 2 during high-price hours (an example of a specific time), so it is convenient for the operator, such as during times when the demand for electricity is high. It becomes easier to receive power supply from EV5 at a good time. For example, when receiving electricity from EV5 during high-price periods, the operator can reduce costs related to capital investment and purchasing power from other companies, and the user can reduce the cost of electricity due to increased costs for the operator. In addition to suppressing price increases, electricity can be sold.

(3) Flow after the end of the high price period FIG. 7 is a flowchart performed by the server 7 after the end of the high price period. FIG. 8 is a flowchart performed by the control device 6 after the high price period ends. Even after the high price period ends, the server 7 and the communication device 6b of the control device 6 continue to communicate.

When the high price time ends, the power port 6a of the control device 6 determines whether the EV 5 was always connected to the control device 6 during the high price time (step S41). If the EV 5 was always connected to the power port 6a of the control device 6 during the high price time (Yes in step S41), the communication device 6b of the control device 6 sends a completion signal to the server 7 (step S42). If there was a time during the high price time when the EV 5 was not connected to the power port 6a of the control device 6 (No in step S41), the communication device 6b of the control device 6 sends a non-completion signal to the server 7 (step S43).

When the server 7 receives the completion signal or non-completion signal (step S31), it records the completion information or non-completion information in the connection information database 14 (step S32). Furthermore, although the user had agreed to the notification requesting connection to the power port 6a of the control device 6 of the EV5 during the high price period (see step S4 in FIG. 4), the EV5 did not receive the completion signal. Also, non-completion information is recorded in the connection information database 14 (step S33).

In this way, for EVs 5 that have agreed to the notification and actually connected the EVs 5 to the power port 6a of the control device 6 during the high price hours, the communication device 6b of the control device 6 transmits a completion signal to the server 7. Since the server 7 can identify the users that connected the EVs 5 to the power port 6a of the control device 6 during the high price hours, it becomes possible to use the completion signal to give a reward to the users, for example, by providing them with a special benefit. This can further encourage users to connect the EVs 5 to the power grid 2 during the high price hours.

(Variation 1) Variation of the flow during high price hours Fig. 9 is a flowchart showing the processing performed by the server 7 during the high price hours in Variation 1. Fig. 10 is a flowchart showing the processing performed by the control device 6 during the high price hours in Variation 1. Variation 1 differs from the present embodiment in that the server 7 compares the remaining battery capacity with the shared power storage capacity.

When the high price time begins, the communication device 6b of the control device 6 obtains not only the identification information of the EV 5 connected to the communication device 6b of the control device 6, but also the remaining battery capacity data, which the communication device 6b transmits to the server 7 (step S61). When the server 7 receives the identification information of the EV 5 and the remaining battery capacity data (step S51), it refers to the notification response database 13 and determines whether the EV 5 has agreed to the request notification (see step S4 in FIG. 4) (step S52). When the server 7 determines that the EV 5 has agreed to the notification, it records in the connection information database 14 that the EV 5 was connected during the high price time (step S53).

Next, the server 7 refers to the EV identification database 12 and identifies the shared power storage capacity of the EV 5 (step S54). Next, the server 7 compares the battery remaining capacity received from the communication device 6b of the control device 6 with the specified shared electricity storage capacity, and determines whether the battery remaining capacity is greater than or equal to the shared electricity storage capacity (step S55). Note that instead of the communication device 6b of the control device 6, the power port 6a of the control device 6 may determine whether the remaining battery capacity is greater than or equal to the shared storage capacity.

If the remaining battery capacity is not equal to or greater than the shared storage capacity (No in step S55), the server 7 records non-completion information for the EV 5 in the connection information database 14 (step S57).

If the remaining battery capacity is equal to or greater than the shared storage capacity (Yes in step S55), and discharging from the EV 5 to the power grid 2 is necessary, the server 7 transmits a power reception signal to the communication device 6b of the control device 6 (step S56). When the communication device 6b of the control device 6 receives the power reception signal from the server 7 (step S62), the power port 6a receives (discharges) power from the EV 5 and supplies it to the power grid 2 (step S63).

In this way, when the communication device 6b of the control device 6 transmits data on the remaining battery capacity to the server 7, the business operator can grasp the amount of power that can be supplied on the server 7 side. Even in this case, the power supply system 1 can compare the remaining battery capacity with the shared storage capacity, as in this embodiment.

(Modification 2) Modification of the flow before the high price hour In this embodiment and Comparative Example 1, the remaining battery capacity is obtained after the high price hour starts, but the power supply system 1 may be configured so that the remaining battery capacity can be obtained before the high price hour starts. Fig. 11 is a flowchart showing the process performed by the server 7 before the high price hour in modification 2.

Steps S71 to S73 in FIG. 11 correspond to steps S1 to S3 in FIG. 4, so their explanation is omitted.

In FIG. 11, when it is confirmed that the current time is within 3 hours (Yes in step S73), the server 7 communicates with each EV 5 via each communication device 6b of each control device 6 and receives data on the current remaining battery capacity of the EV 5 (step S74). The server 7 records the received remaining battery capacity in the notification response database 13 (step S75).

Next, the server 7 notifies the user's communication terminal of the start and end times of the high price period, and sends a notification requesting that the EV 5 be connected to the power port 6a of the control device 6 during the high price period (step S76).

At this time, the server 7 may use the remaining battery capacity of the EV 5 to select the notification target. For example, at the time when the server 7 acquires the remaining battery capacity of the EV5 via the communication device 6b of the control device 6, the communication terminal of the user of the EV5 whose remaining battery capacity is lower than the shared storage capacity is The server 7 does not need to notify the high price time by predicting that the battery remaining capacity will be lower than the shared storage capacity by the time the price time starts.

Alternatively, even if the remaining battery capacity is lower than the shared storage capacity at the time when the server 7 acquires the remaining battery capacity of the EV5, the distance from the EV5 to the control device 6 in the user's home etc. is sufficiently close (for example, , within 3 m), if the EV5 is expected to be charged by the high price time, the server 7 predicts that the remaining battery capacity will exceed the shared storage capacity by the start of the high price time, and The user's communication terminal may be notified of the high price time. Furthermore, even if the remaining battery capacity exceeds the shared power storage capacity, if the distance from the EV 5 to the control device 6 in the user's home is long, the remaining battery capacity may exceed the shared power storage capacity by the time it returns to the control device 6. If it is predicted that the amount will fall below the capacity, the server 7 does not need to notify the user's communication terminal of the high price time. In order to make these predictions, the server 7 obtains information on the current location of the EV 5 along with information on the remaining battery capacity from the communication device 6b of the control device 6, and compares the information with the pre-recorded location information of the user's control device 6. It may be configured to match.

After notifying the user's communication terminal to request connection of the EV 5 to the power port 6a of the control device 6, the server 7 determines whether or not a reply has been received for each user (step S77). Responses from users are recorded in a notification response database 13 connected to the server 7. If no response is obtained from the user (No in step S77), the server 7 records unanswered information indicating that there was no response in the notification response database 13 (step S78).

When a response is obtained from the user (Yes in step S77), the server 7 judges whether the user agrees to connect the EV 5 to the power port 6a of the control device 6 during the high price time (step S79). When the user agrees to the notification (Yes in step S79), the server 7 records the consent information in the notification response database 13 (step S80). When the user rejects the notification (No in step S79), the server 7 records the rejection information in the notification response database 13 (step S81).

Next, the server 7 calculates the total shared storage capacity, which is the total amount of electricity that can be discharged from all EVs 5 that have agreed to the notification, based on the consent information recorded in the notification response database 13 (step S82). The time when the server 7 starts calculating the total shared storage capacity is, for example, 30 minutes before the start of the high price period.

As in variant example 2, the server 7 can obtain the remaining battery capacity in advance, allowing the total storage capacity to be roughly calculated. Since the amount of electricity obtained from the EVs 5 can be predicted, it becomes easier for the business operator to operate the electricity supply system 1 during high-price times.

(Hardware configuration example)
The server 7 can be realized by executing a program corresponding to the processing performed by the server 7, using hardware resources such as a CPU and memory built into a computer. The program can be recorded on a (non-transitory) computer-readable recording medium and stored or distributed. The program can also be provided via a network such as the Internet or e-mail.

Figure 9 is a diagram showing an example of the hardware configuration of a server. The computer serving as a server in Figure 9 has a drive device 1000, an auxiliary storage device 1002, a memory device 1003, a CPU 1004, an interface device 1005, a display device 1006, an input device 1007, an output device 1008, etc., all of which are interconnected by a bus BS.

The program that realizes the processing on the computer is provided by a recording medium 1001, such as a CD-ROM or a memory card. When the recording medium 1001 storing the program is set in the drive device 1000, the program is installed from the recording medium 1001 via the drive device 1000 into the auxiliary storage device 1002. However, the program does not necessarily have to be installed from the recording medium 1001, but may be downloaded from another computer via a network. The auxiliary storage device 1002 stores the installed program as well as necessary files, data, etc.

When an instruction to start a program is received, the memory device 1003 reads out and stores the program from the auxiliary storage device 1002. The CPU 1004 realizes the functions related to the device in accordance with the program stored in the memory device 1003. The interface device 1005 is used as an interface for connecting to a network, etc. The display device 1006 displays a GUI (Graphical User Interface) or the like according to a program. The input device 1007 is composed of a keyboard and mouse, buttons, a touch panel, etc., and is used to input various operational instructions. The output device 1008 outputs the results of calculations.

The power port 6a and communication device 6b of the control device 6 have the same hardware configuration as the server 7, so a description of them will be omitted.

As mentioned above, this embodiment is an example, and is not limited to the embodiment described above, and can be modified, improved, etc. as appropriate. In addition, the material, shape, size, numerical value, form, number, arrangement location, etc. of each component in the above-described embodiments are arbitrary as long as they can disclose the present invention, and are not limited.

For example, the four databases (11 to 14) shown in FIG. 2 may be constructed within the server 7, or may be constructed within another server outside the server 7. Also, each of the four databases (11 to 14) may be constructed within a different server outside the server 7.
