METHOD AND DEVICE FOR DETECTING CHARGING ABNORMALITY, AND STORAGE MEDIUM

This application provides a method and device for detecting charging abnormality, and a storage medium. In this application, a first sampling moment corresponding to a first minimum voltage in n sampled voltages is determined based on n consecutive sampled voltages of a first cell from an end moment of an icharging phase to an end moment of an (i+1)charging phase in a kcharging process. A second sampling moment corresponding to a second minimum voltage in any one of the first (k−1)charging processes can be determined in the same way. Then abnormality of the kcharging process is determined.
