Title:
CHARGING METHOD AND APPARATUS, AND ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/220979
Kind Code:
A1
Abstract:
Disclosed in the present application are a charging method and apparatus, and an electronic device and a storage medium. The method comprises: acquiring a charging parameter of each battery module in a battery pack in the current charging mode, wherein the battery pack has a plurality of battery modules, and the current charging mode comprises a series charging mode; and if it is determined, on the basis of the charging parameters of the battery modules, that any two battery modules meet a charging conversion condition, then controlling the plurality of battery modules to be switched from the series charging mode to a parallel charging mode. In this way, conversion from series charging to parallel charging is realized before charging and discharging currents of a battery pack become excessive, such that the risk of lithium precipitation of a battery is reduced, and the charging safety of the battery pack is improved.
