Embodiment 1
[0037] An embodiment of the present invention provides a method for charging and discharging a battery system. The battery system includes a voltage control module, a battery management module, and N cells. The battery management module is used to monitor the voltage of each cell. The voltage control module is connected to The charging and discharging interface of the battery system, such as figure 1 As shown, the method includes:
[0038] S101, obtaining the voltage of each battery cell through the battery management module;
[0039] S102. Based on the voltage of each cell, determine a target cell, the target cell is the cell with the highest voltage or the cell with the lowest voltage, and there are one or more target cells;
[0040] S103, generating a control strategy based on the target cell;
[0041] S104, based on the control strategy, charge or discharge the target cell, so as to maximize the amount of electricity charged into the battery system or to maximize the amo...
