Abstract
A battery management apparatus according to an embodiment includes a side reaction determining unit configured to determine a target peak in a differential profile representing a 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. A side reaction cause determining unit is configured to determine a resistance pattern of the battery with respect to a criterion voltage region in a resistance profile representing a corresponding relationship between voltage and resistance of the battery, and determine an occurrence cause of the side reaction based on the determined resistance pattern.
