BATTERY MANAGEMENT APPARATUS AND METHOD

A battery management apparatus according to an embodiment of the present disclosure includes a side reaction determining unit configured to determine a target peak in a differential profile representing the corresponding relationship between voltage and differential capacity of a battery, and determine whether a side reaction occurs in the battery by comparing a criterion peak of a preset criterion profile with the target peak; and a side reaction cause determining unit configured to determine a resistance pattern of the battery with respect to a criterion voltage region in a resistance profile representing the corresponding relationship between voltage and resistance of the battery, and determine an occurrence cause of the side reaction based on the determined resistance pattern.
