Document Type and Number:
WIPO Patent Application WO/2020/149557
Kind Code:
A1
Abstract:
A battery management apparatus according to the present invention comprises: a voltage measurement unit configured to measure a battery voltage of a battery; a bending degree measurement unit provided on at least one side of the battery to measure a battery bending degree of the battery; and a processor configured to receive the battery voltage from the voltage measurement unit, receive the battery bending degree from the bending degree measurement unit, set a reference bending degree according to whether the battery voltage is included in any one of an over-discharge voltage section, an allowable voltage section, and an over-charge voltage section, compare the battery bending degree with the reference bending degree, and perform a protection operation for the battery on the basis of a result of comparing the bending degrees.
