The present invention relates to a battery balancing apparatus for balancing a battery in a sleep mode of an electric vehicle. The battery balancing apparatus for balancing a battery comprises: a measuring unit for measuring the temperature and the voltage of a plurality of batteries; a balancing control unit for comparing the measured data with predetermined reference data based on the pre-balancing temperature and the measured voltage measured by the measuring unit and determining the number of balancing target batteries of the plurality of batteries; and a balancing unit for balancing the balancing target batteries under the control of the balancing control unit, wherein the balancing control unit determines the number of the balancing target batteries before the electric vehicle enters the sleep mode.

    본 발명은 전기자동차의 슬립모드(sleep mode)에서 전지의 밸런싱(balancing)을 수행하는 전지 밸런싱 장치에 있어서, 복수개 전지의 온도 및 전압을 측정하는 측정부; 상기 측정부로부터 측정된 밸런싱 전 온도 및 측정전압을 기초로 기 결정된 기준 데이터와 비교하여 상기 복수개 전지의 밸런싱 대상 전지 개수를 결정하는 밸런싱 제어부; 및 상기 밸런싱 제어부의 제어에 따라 상기 밸런싱 대상 전지의 밸런싱을 수행하는 밸런싱부;를 포함하고, 상기 밸런싱 제어부는 전기자동차의 슬립모드 진입 전 상기 밸런싱 대상 전지 개수를 결정하는, 전지 밸런싱 장치에 관한 것이다.
