본 발명의 일 실시예에 의한 전력 소모를 최소화한 과충전 방지 장치는, 차량의 시동 온 또는 오프 상태에 따라 배터리 셀에서 검출되는 전압의 공급을 단속하는 스위칭부; 및 상기 스위칭부에서 출력되는 상기 배터리 셀의 전압에 기반하여 상기 배터리 셀이 과충전되는 경우 메인 릴레이를 오프시켜 배터리 모듈로의 전력 공급을 중단하는 과충전 방지 회로를 포함하여, 차량의 시동 온 상태에서만 배터리 셀의 전압을 검출하여 전력 소모를 최소화함으로써 셀 간 전압 편차를 줄여 배터리의 수명 단축을 방지할 수 있다.

    Disclosed herein is an overcharge protection apparatus with minimized power consumption. An overcharge protection apparatus with minimized power consumption according to an embodiment includes a switching unit (SW1) for controlling supply of voltage detected in a battery cell depending on an ignition-on or off state of a vehicle, and an overcharge prevention circuit (102, ZD) for, when the battery cell ("cell") is overcharged based on the voltage of the battery cell output from the switching unit, turning off a main relay (RL3), thus interrupting supply of power to a battery module, so that the voltage of the battery cell is detected only in an ignition-on state of a vehicle and power consumption is minimized, thus preventing the lifespan of a battery from being shortened by reducing a voltage difference between cells.
