According to a preferred embodiment of the present invention, provided is an overcharge prevention device of a battery which is configured to comprise a plurality of battery cells connected in series to each other. The overcharge prevention device of a battery comprises: an overcharge determination unit determining overcharge of a battery cell; a balancing unit operated by the overcharge determination unit to balance a first overvoltage when the battery cell is overcharged to generate the first overvoltage as a result of the determination; and an overcharge cell bypass unit operated by the balancing unit to release a series connection between the battery cell and the peripheral battery cell when a voltage greater than the first overvoltage is generated in the battery cell after the balancing.

    본 발명의 바람직한 실시예에 따른 배터리의 과충전 방지 장치는, 서로 직렬로 연결된 복수의 배터리 셀을 포함하여 구성되는 배터리의 과충전 방지 장치에 있어서, 상기 배터리 셀의 과충전 여부를 판단하는 과충전 판단부, 판단 결과 상기 배터리 셀이 과충전되어 제1 과전압이 발생하는 경우, 상기 과충전 판단부에 의해 동작하여 상기 제1 과전압을 밸런싱하는 밸런싱부, 및 상기 밸런싱 이후 상기 제1 과전압보다 큰 전압이 상기 배터리 셀에 발생하는 경우, 상기 밸런싱부에 의해 동작하여 상기 배터리 셀과 주변 배터리 셀의 직렬 연결을 해제하는 과충전셀 우회부를 포함한다.
