Abstract

The invention discloses method and apparatus for operation and maintenance of a battery and an electronic device. The method includes: performing a charging/discharging process on a to-be-analyzed battery cluster, and determining key battery parameters (KBP) of a plurality of cells in the battery cluster; determining whether the battery cluster is abnormal depending on whether the KBPs of the cells in the battery cluster exceed a normal range; and performing operation and maintenance on the battery cluster in a case that the battery cluster is abnormal. The internal resistance, the capacity parameter, and the self-discharge parameter of the cells are used as the KBPs of the cells. Based on the KBPs, whether the cells are abnormal can be determined more accurately, and the cause of the abnormality can be determined. Accordingly, more accurate operation and maintenance can be subsequently realized for the battery cluster when required.
