More Information
Summary:A battery management apparatus according to the present disclosure includes a voltage measuring unit configured to measure a battery voltage of a battery, a degree of bending measuring unit provided on at least one side of the battery and configured to measure a degree of battery bending of the battery, and a processor configured to receive the battery voltage from the voltage measuring unit, receive the degree of battery bending from the degree of bending measuring unit, set a base degree of bending according to a voltage range to which the battery voltage belongs among an overdischarge voltage range, an allowable voltage range and an overcharge voltage range, compare the degree of battery bending with the base degree of bending to determine which is greater, and perform a protection operation for the battery based on a degree of bending comparison result.
