Abstract
A battery management system according to the present disclosure includes a swelling detector including at least one sensor configured to detect a swelling status of a battery cell; and a control circuit configured to generate first time-series data of the swelling status repeatedly detected during a charging procedure included in a charge/discharge cycle of the battery cell. The control circuit is configured to determine a first change amount of the swelling status in the charging procedure from the first time-series data. The control circuit is configured to determine whether the battery cell is shorted internally based on the first change amount.
