BATTERY EQUALIZATION METHOD AND SYSTEM, VEHICLE, STORAGE MEDIUM, AND ELECTRONIC DEVICE

The present application relates to a battery equalization method and system, a vehicle, a storage medium, and an electronic device. The method includes: obtaining a voltage value of a to-be-equalized cell in a battery pack; obtaining a reference voltage value required for equalization; determining a target equalization duration of the to-be-equalized cell according to a voltage value of the to-be-equalized cell, the reference voltage value, and a preset equalization duty cycle, where the equalization duty cycle is a ratio of an equalization period in a unit cycle to the unit cycle, and the unit cycle includes the equalization period and a sampling period; and controlling equalization of the to-be-equalized cell in the equalization period in the unit cycle according to the target equalization duration. According to this method, sampling is separated from equalization in a unit cycle, thereby ensuring accuracy of collected battery information, making the calculated equalization duration relatively accurate, and improving equalization effects of the battery pack.
