Abstract

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).
