Abstract

A battery management apparatus according to an embodiment disclosed herein includes a sensor configured to obtain a voltage of a battery unit and a controller configured to generate a differential profile for a first differential value that is variance of the voltage with respect to a variance of a state of charge (SOC) of the battery unit, based on the SOC and the voltage of the battery unit, detect an SOC corresponding to each of second differential values included in a threshold range among second differential values obtained by differentiating the differential profile, detect, from the differential profile, peak values of the differential profile among first differential values corresponding to the detected SOC, and determine a state of the battery unit based on the peak values of the differential profile.
