본 발명은, 각각의 배터리 셀(BT1-BTX)을 위한 차동 전압 유닛(30)들을 포함하며, 부하 상태에서 배터리 스트링(10)의 배터리 셀(BT1-BTX)들을 모니터링하기 위한 장치(1)에 관한 것이며, 각각의 차동 전압 유닛(30)의 하류에는 대역 통과 필터(35)가 배열되고, 대역 통과 필터(35)들은 하류에 배열된 평활 회로(37)를 구비한 정류기 회로(36)들과 연결되며, 장치(1)는, 평활 회로(37)들의 출력 신호들이 평가 유닛(40)에 공급되고, 정규화된 출력 신호와 비교되어 편차들을 형성하도록 형성된다.
A device for monitoring battery cells of a battery string under load condition. The device has differential voltage units for each battery cell, wherein a band-pass filter is arranged downstream of each differential voltage unit, wherein the band-pass filters are connected to rectifier circuits with a smoothing circuit arranged downstream, and wherein the device is designed so the output signals of the smoothing circuits are supplied to an evaluation unit and are compared for deviations in relation to a standardized output signal.
