Abstract: A battery state estimation apparatus includes a sensing data acquirer configured to acquire sensing data of a battery. The apparatus further includes a state of health (SOH) information estimator configured to divide the sensing data based on a predetermined time interval, extract a segment comprising a predetermined number of items of the divided sensing data, and estimate SOH information of the battery based on the segments.
