BATTERY EQUALIZATION METHOD AND SYSTEM, VEHICLE, STORAGE MEDIUM, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/042400
Kind Code:
A1
Abstract:
A battery equalization method and system, a vehicle, a storage medium, and an electronic device. The method comprises: determining cells needing to be equalized in a battery pack according to cell information of cells of the battery pack obtained within a sampling period of a unit cycle (S51); obtaining, according to the cell information of the cells, values of performance parameters of the cells needing to be equalized and reference values of the performance parameters (S52); determining, according to the values of performance parameters of the cells needing to be equalized, the reference values of the performance parameters, and a preset equalization duty cycle, equalizing current of the cells needing to be equalized (S53); and according to the equalizing current, controlling, within an equalization period of the unit cycle, equalization of the cells needing to be equalized (S54). Therefore, cell information acquisition and equalization can be performed by time; according to the cell information of the cells, the equalizing current of the cells is determined to perform equalization, so that equalization efficiency can be improved.
