METHOD AND APPARATUS FOR CONTROLLING PARALLEL BATTERY SYSTEM, AND ELECTRONIC DEVICE

WIPO Patent Application WO/2022/110601

A1

The present application provides a method and an apparatus for controlling a parallel battery system, and an electronic device. The method comprises: acquiring the current working mode of a parallel battery system and the current system voltages corresponding to battery subsystems; calculating the current system average voltage of the parallel battery system according to the current system voltages corresponding to the battery subsystems; and according to the current working mode and the relationship between the current system voltages corresponding to the battery subsystems and the current system average voltage, performing a current working mode-based charging or discharging operation on the battery subsystems until the current system voltages corresponding to the battery subsystems and the current system average voltage satisfy a preset system voltage balance relationship. By controlling the charging and discharging operations of the battery subsystems, the voltage balance of the parallel battery system is adjusted, improving the efficiency of adjusting the voltage balance, and furthermore, during adjustment, the parallel battery system is still in a normal working state, ensuring the working efficiency of the parallel battery system.
