Title:
BATTERY CELL EQUALIZATION METHOD FOR BATTERY PACK
Document Type and Number:
WIPO Patent Application WO/2023/082794
Kind Code:
A1
Abstract:
Provided in the present invention is a battery cell equalization method for a battery pack. The method comprises: when a processor goes into hibernation, determining whether a battery cell of a battery pack needs to be equalized; and when it is determined that the battery cell needs to be equalized, performing offline equalization on the battery cell when the processor is hibernating. By means of the present invention, offline equalization is performed on a battery cell of a battery pack by utilizing the hibernation time of a processor, such that the problem of it being impossible to complete battery cell equalization due to an insufficient online equalization time of a large-capacity battery pack or a battery pack having a very large self-discharge rate is solved, thereby prolonging the service life of the battery cell, and improving the energy utilization efficiency of the battery pack.
