The present invention relates to a battery management system and a battery management method. The battery management system for managing a battery including at least one cell comprises: an SOH (State of Charge) estimating unit for determining estimation parameters for estimating an SOC of the battery; and a controller for updating a pattern table for estimating a pattern of use on a charge and discharge cycle of the battery, based on the estimation parameters. The pattern table includes a plurality of pattern counters, and the plurality of pattern counters correspond to a plurality of estimation ranges, respectively. The controller determines to which estimation range from among the plurality of estimation ranges the estimation parameters correspond, and updates a value of a pattern counter corresponding to the determined estimation range from among the plurality of pattern counters. The battery management system and the battery management method according to the present invention may regularly update and record a pattern of use for charge and discharge cycles of the battery in order to estimate and analyze an accurate pattern of use for the battery, so as to effectively perform an estimation of the SOH of the battery and maintenance and repair. |
