Apparatus and method for managing battery

Abstract

A battery managing apparatus according to an embodiment of the present disclosure includes a measurement unit configured to measure the voltage of a battery that is charged by repeating a charging period and a resting period; and a control unit configured to calculate a resistance corresponding to each of a plurality of resting periods, generate a first profile indicating a correspondence relationship between a state of charge (SOC) and the resistance of the battery, divide an SOC section of the first profile into a plurality of unit sections, and calculate a summed resistance of the battery based on a weight and a reference resistance corresponding to each of the plurality of unit sections.
