The present invention provides a battery management system which prevents a sensing integrated circuit (IC) from an overvoltage and a reverse voltage of a bus-bar and an operating method thereof. According to the present invention, the battery management system comprises: a sensing integrated circuit monitoring voltages of each of battery cells connected to a bus-bar; and a voltage protection circuit measuring both voltages of the bus-bar, distinguishing whether the measured voltage is in an input voltage range and outputting the measure voltage to input pins of the sensing integrated circuit when the measured voltage is in a normal range.

    본 발명에 따른 배터리 관리 시스템은, 버스바에 연결된 배터리 셀들의 각각의 전압을 모니터링 하는 센싱 집적회로, 및 상기 버스바의 양단 전압을 측정하고, 상기 측정된 전압이 입력 전압 범위를 이내인지를 판별하고, 상기 측정된 전압이 정상 범위 이내일 때, 상기 측정된 전압을 상기 센싱 집적회로의 입력핀들로 출력하는 전압 보호 회로를 포함할 수 있다.
