전지 시스템용 제어 유닛은, 상기 전지 시스템의 복수의 전지 셀 중 적어도 하나의 상태를 나타내는 센서 신호를 수신하는 입력 노드, 상기 입력 노드에 연결되며, 상기 센서 신호에 기초하여 제1제어 신호를 생성하는 마이크로컨트롤러, 및 상기 센서 신호, 상기 제1제어 신호 및 상기 마이크로컨트롤러의 작동 상태를 나타내는 폴트 신호를 수신하고, 상기 센서 신호에 대응하여 제2제어 신호를 생성하며, 상기 폴트 신호에 기초하여 상기 제1제어 신호 및 상기 제2제어 신호 중 하나를 상기 제어 유닛의 출력 노드에 전달함으로써, 상기 전지 시스템의 전력 스위치를 제어하는 스위치 제어 회로를 포함할 수 있다.

    The present invention refers to a control unit (20) for a battery system (100), the control unit (20) comprising an input node (21) that is configured for receiving a sensor signal (40) indicative of a state of at least one of a plurality of battery cells (10) of the battery system (100), a front end circuit (22) that is connected to the input node (21) and configured for generating a state signal (41) based on the sensor signal (40), a microcontroller (24) connected to the front end circuit (22) and configured for generating a first control signal (42) based on the state signal (41), and a switch control circuit (25). The switch control circuit (25) is configured for controlling a power switch (13) of the battery system by receiving the state signal (41), the first control signal (42), and a fault signal (43) indicative of an operation state of the microcontroller (24), by generating a second control signal (44) based on the state signal (41), and by transmitting one of the first control signal (42) and the second control signal (44) to an output node (27) of the control unit (20) based on the received fault signal (43). The invention further relates to a battery system (100) with such control unit (20).
