Abstract:
1. A battery management system for managing a battery including at least one cell, the system comprising: an SOC (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, wherein the pattern table includes a plurality of pattern counters, the plurality of pattern counters corresponding to a plurality of estimation ranges, respectively, and 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, and wherein the number of the plurality of estimation ranges is N (where N>1), the size of each of the plurality of estimation ranges is K, each of the plurality of estimation ranges has an index n set from 1 to N, and each of the plurality of estimation ranges has a range between 100-nK and 100-(n−1)K.
