Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The embodiments described by way of example below are not representative of all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus consistent with some aspects of the disclosure as detailed in the accompanying claims. The features of the following examples and embodiments may be combined with each other without any conflict.
In order to solve the technical problems, embodiments of the present disclosure provide a charge and discharge control method and apparatus, an electronic device, and a readable storage medium. The charge and discharge control method may be applied to electronic devices, which may include, but are not limited to, smart phones, tablet computers, personal assistants, etc. provided with 2 batteries. Referring to fig. 1, the electronic device includes a main board, a first battery circuit board, a second battery circuit board, and a power management chip; the first battery and the second battery are arranged in parallel; the main board is provided with a first fuel gauge, the second battery circuit board is provided with a second fuel gauge, so that the first fuel gauge can collect equipment charge and discharge data of the electronic equipment, and the second fuel gauge can collect second charge and discharge data of the second battery. The inventive concept of the present disclosure is that the first device charge and discharge data and the second charge and discharge data calculate the first charge and discharge data of the first battery, thereby achieving an effect that an electricity meter is provided at the first battery.
Fig. 2 is a flowchart illustrating a charge and discharge control method according to an exemplary embodiment. Referring to fig. 2, a charge and discharge control method includes steps 21 to 23.
In step 21, device charge and discharge data of the electronic device acquired by the first fuel gauge is acquired, and second charge and discharge data of the second battery acquired by the second fuel gauge is acquired.
In this embodiment, the processor of the electronic device may communicate with the first fuel gauge and the second fuel gauge, respectively, to obtain the charge and discharge data uploaded by the first fuel gauge and the second fuel gauge, respectively. Of course, the first electricity meter and the second electricity meter can store the collected charging and discharging data to the designated position, and the processor can read the charging and discharging data from the designated position according to time sequence. In an example, a first fuel gauge may store device charge and discharge data of an electronic device to a first designated location, and a second fuel gauge may store second charge and discharge data of a second battery to a second designated location. In this way, the processor can read the charge and discharge data from the first designated position and the second designated position, respectively.
It should be noted that the second charge and discharge data may include a charge voltage (V1), a charge current (I1), a present charge amount (RSOC 1), and a full charge amount (FCC 1) of the second battery during the charge and discharge. The device charge and discharge data may include a charge voltage (V), a charge current (I), a present power level (RSOC), and a full power level (FCC) of the electronic device during the charge and discharge. Wherein, full charge represents the amount of electricity accumulated from the process of rsoc=100% to the process of discharging rsoc=0% after the battery is full, wherein rsoc=0% represents the amount of electricity that the battery voltage drops to the shutdown voltage of 3.4V, i.e. the battery can release from full charge to shutdown. For convenience of description, the following embodiments refer to the full power of the first battery as the first full power, and the full power of the second battery as the second full power, to illustrate the difference.
In an example, the initial value (fcc_st2) of the second full charge of the second battery may be obtained by learning a multi-discharge charging method. For example, the charging and discharging operations are performed in accordance with the charging and discharging manner in the instructions for use of the second battery; after a plurality of repeated operations, the second electricity meter may acquire an initial value (fcc_st2) of the second full charge of the second battery.
In another example, the initial value of the first full charge level (fcc_st1) of the first battery may pass a required charge level between a charge cutoff voltage and a shutdown voltage of the first battery. For example, the first battery is charged to a charge cutoff voltage according to the charging method of the instruction of the first battery, and then the first battery is discharged to a shutdown voltage according to the discharging method, so that the electric quantity discharged by the first battery can be determined as the initial value (fcc_st1) of the first full-charge electric quantity.
It should be noted that, in the process of testing the full-power circuit, the first battery and the second battery are not assembled according to the scheme illustrated in fig. 1 but are separately tested. It is necessary to determine that the current amounts of electricity (RSOC) of the first battery and the second battery are both preset amounts of electricity, for example rsoc=95%, before assembling the first battery and the second battery. The electric quantity display value (UISOC) of the electronic equipment is 100%, namely, the electronic equipment is in a full-power state. The RSOC represents the current power of the battery, and may also be referred to as the remaining power of the battery or the power that the battery can release when the electronic device is turned off.
In step 22, first charge-discharge data of the first battery is determined based on the device charge-discharge data and the second charge-discharge data.
In this embodiment, the processor may obtain a difference between charge and discharge data of the device and the second charge and discharge data, to obtain first charge and discharge data of the first battery.
For example, the processor may obtain a device full power level (FCC 1) and a device current power level (RSOC) in the device charge-discharge data, and obtain a second full power level (FCC 2) and a second current power level (RSOC 2) in the second charge-discharge data. The processor may then obtain a power difference between the full power of the device and the second full power, the subsequent embodiment being referred to as a first full power (FCC 1); and obtaining a power difference value between the current power of the device and the second current power to obtain the current power of the first battery, wherein the subsequent embodiment is called as the first current power. For another example, the processor may obtain a charging current in the charging and discharging data of the device and a second current in the second charging and discharging data, and obtain a current difference between the two, that is, the first current of the first battery.
It should be noted that, the processor may obtain corresponding charge and discharge parameters from the charge and discharge data of the device and the second charge and discharge data according to actual requirements, so as to calculate parameter values corresponding to the first battery, for example, the first current electric quantity and the first full electric quantity. Finally, these parameter values constitute first charge-discharge data of the first battery.
In step 23, the first battery and the second battery are respectively controlled to be charged and discharged according to the first charging and discharging data and the second charging and discharging data.
In this embodiment, taking a charging process as an example, the processor may control the charging and discharging of the first battery and the second battery according to the first charging and discharging data and the second charging and discharging data, respectively, see fig. 3, including steps 31 to 34.
In step 31, when the voltage of the first battery is less than or equal to a first voltage threshold and the voltage of the second battery is less than or equal to a second voltage threshold, controlling the power management chip to output a charging current; the charging current comprises a first charging current corresponding to the first battery and a second charging current corresponding to the second battery.
In this step, the processor may acquire a first voltage threshold of the first battery and a voltage of the first battery, and then compare the voltage of the first battery with the first voltage threshold, thereby determining a magnitude relation between the voltage of the first battery and the first voltage threshold. The processor may determine that the first battery is in a full state when the voltage of the first battery is greater than the first voltage threshold, at which point the processor may end charging the first battery. The first voltage threshold refers to a voltage of the first battery under the condition of full power, for example, the first voltage threshold may be a maximum voltage of the first battery, or a product of a first preset voltage proportion (such as 95% -99%) and the maximum voltage of the first battery may be set according to a specific scenario, which is not limited herein.
In this step, the processor may acquire a second voltage threshold of the second battery and a voltage of the second battery, and then compare the voltage of the second battery with the second voltage threshold, thereby determining a magnitude relation between the voltage of the second battery and the second voltage threshold. When the voltage of the second battery is greater than the second voltage threshold, the processor may determine that the second battery is in a full state, at which point the processor may end charging the second battery. The second voltage threshold refers to a voltage of the second battery under the condition of full power, for example, the second voltage threshold may be a maximum voltage of the second battery, or a product of a second preset voltage proportion (such as 95% -99%) and the maximum voltage of the second battery, which may be set according to a specific scenario, and is not limited herein.
In this step, when the (current) voltage of the first battery is less than or equal to the first voltage threshold and the (current) voltage of the second battery is less than or equal to the second voltage threshold, the processor may control the Power management chip (Power MANAGEMENT IC, PMIC) to output the charging current. It is understood that the above-mentioned charging current is the total current of the electronic device, and may include a first charging current corresponding to the first battery and a second charging current corresponding to the second battery.
It should be noted that, when the first battery and the second battery need to be charged, the power management chip may output charging currents required by the two batteries; when one of the first battery and the second battery is charged and the other battery needs to be charged, the power management chip can output the charging current required by the battery until the battery is charged fully.
In step 32, when it is determined that the first charging current is less than or equal to a first current threshold, the processor may control the power management chip to charge the first battery with the first charging current until the charge of the first battery is equal to a first charge threshold. The first current threshold is the maximum current when the first battery is charged, or the product of the first preset current ratio (e.g. 95% -99%) and the maximum current of the first battery, which may be set according to a specific scenario, and is not limited herein.
In step 33, when it is determined that the second charging current is less than or equal to the second current threshold, the processor may control the power management chip to charge the second battery with the second charging current until the charge of the second battery is equal to the second charge threshold. The second current threshold is the maximum current when the second battery is charged, or the product of the second preset current ratio (e.g. 95% -99%) and the maximum current of the second battery, which may be set according to a specific scenario, and is not limited herein.
In step 34, when the power display value is equal to the preset value, the power management chip is controlled to output a charging current with a preset magnitude until the charging is finished. Wherein, the range of the preset value is 96% -100%, and in one example, the preset value is 100%.
In this step, the processor may obtain the power display value of the electronic device according to the first power data in the first charge and discharge data and the second power data in the second charge and discharge data. The first electric quantity data refer to current electric quantity data of the first battery, and the second electric quantity data refer to current electric quantity data of the second battery.
The processor may obtain the power display value of the electronic device according to the first power data in the first charge and discharge data and the second power data in the second charge and discharge data, see fig. 4, including steps 41 to 43.
In step 41, the processor may obtain full power of the first battery and the second battery, respectively, to obtain a first full power and a second full power. The first full power FCC1 and the second full power FCC2 may be obtained according to the scheme of step 22, which is not described herein.
In step 42, the processor may obtain a first weight value corresponding to the first battery according to the first full power and the second full power, and obtain a second weight value corresponding to the second battery according to the first full power and the second full power. For example, the first weight value is FCC 1/(FCC 1+fcc 2); the second weight value is FCC 2/(FCC 1+ FCC 2).
In step 43, the processor may calculate a power weighting value according to the first power quantity and the first weight value, and the second charge and discharge data and the second weight value, so as to obtain the power display value. For example UISOC =rsoc1×fcc 1/(FCC 1+fcc 2) +rsoc2×fcc 2/(FCC 1+fcc 2).
After the electric quantity display value is obtained, the processor can compare the magnitude relation between the electric quantity display value and the preset value, and when the electric quantity display value is equal to the preset value (such as 100%), the processor can control the power management chip to output charging current (such as 500mA, adjustable) with the preset magnitude until the charging is finished.
In this embodiment, taking a discharging process as an example, the processor may control the charging and discharging of the first battery and the second battery according to the first charging and discharging data and the second charging and discharging data, respectively, see fig. 5, including steps 51 to 54.
In step 51, when the discharge voltage of the first battery is greater than or equal to the first discharge voltage threshold and the voltage of the second battery is greater than or equal to the second discharge voltage threshold, controlling the power management chip to output a discharge current; the discharge current comprises a first discharge current corresponding to the first battery and a second discharge current corresponding to the second battery.
In this step, the processor may acquire a first discharge voltage threshold of the first battery and a discharge voltage of the first battery, and then compare the discharge voltage of the first battery with the first discharge voltage threshold, thereby determining a magnitude relation between the discharge voltage of the first battery and the first discharge voltage threshold. When the discharge voltage of the first battery is less than the first discharge voltage threshold, the processor may determine that the first battery is in a non-electric state, and at this time, the processor may control the protection circuit to turn off the discharge switch. The first discharging voltage threshold is a voltage which can be reached after the first battery is discharged, or a shutdown voltage of the electronic device. In an example, the first discharge voltage threshold is 3.4V.
In this step, the processor may acquire a second discharge voltage threshold of the second battery and a discharge voltage of the second battery, and then compare the discharge voltage of the second battery with the second discharge voltage threshold, thereby determining a magnitude relation between the discharge voltage of the second battery and the second discharge voltage threshold. When the discharge voltage of the second battery is smaller than the second discharge voltage threshold value, the processor can determine that the second battery is in a non-electric state, and the processor can control the protection circuit to turn off the discharge switch. The second discharging voltage threshold is a voltage which can be reached after the second battery is discharged, or a shutdown voltage of the electronic device. In an example, the second discharge voltage threshold is 3.4V.
In this step, when the discharge voltage of the first battery is greater than or equal to the first discharge voltage threshold and the discharge voltage of the second battery is greater than or equal to the second discharge voltage threshold, the processor may control the Power management chip (Power MANAGEMENT IC, PMIC) to output the charging current. It is understood that the above-mentioned discharging current is the total current of the electronic device, and may include a first discharging current corresponding to the first battery and a second discharging current corresponding to the second battery.
In step 52, when it is determined that the first discharge current is less than or equal to a first discharge current threshold, the processor may control the first battery to output the first discharge current until the charge of the first battery is 0.
In step 53, when it is determined that the second discharge current is less than or equal to a second discharge current threshold, the processor may control the second battery to output the second discharge current until the electric quantity of the second battery is 0.
