Abstract
A method of managing a battery includes preprocessing a voltage data sequence and a current data sequence of a battery; estimating an internal resistance of the battery based on the preprocessed voltage data sequence, the preprocessed current data sequence, and an internal resistance estimation model in which an internal resistance change due to a battery degradation is modeled; and determining state information of the battery based on the estimated internal resistance.
