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

WIPO Patent Application WO/2019/042364

A1

A battery equalization method comprises: obtaining load voltage values of cells to be equalized in a battery pack (104) (S51); obtaining reference load voltage values required for equalization (S52); determining, according to the load voltage values of the cells to be equalized and to the reference load voltage values, a target equalization duration of the cells to be equalized (S53); and equalizing, according to the target equalization duration, the cells to be equalized (S54). Also disclosed are a battery equalization system using the method, a vehicle using the battery equalization system, a storage medium storing a program executing the method, and an electronic device comprising the medium. The target equalization duration on which the equalization process is based is calculated according to the differences between the load voltage values of the cells to be equalized and the reference load voltage values, and therefore, the equalization duration is more accurate, thereby making the equalization process also more accurate so as to avoid that the equalization duration is too long or too short.
