According to an embodiment of the present invention, an overcharge protection apparatus with minimized power consumption comprises: a switching unit for regulating supplying voltage detected in a battery cell according to an on or an off state of stating a vehicle; and an overcharge protection circuit for suspending voltage supply to a battery module by turning off a main relay when the battery cell is overcharged based on voltage of the battery cell outputted by the switching unit. Therefore, by minimizing power consumption by detecting voltage of the battery cell when a vehicle is set on, the durability shorten can be prevented by reducing voltage variation between cells.

    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.
