  • Battery system for use on a vehicle electrical system of a motor vehicle
    Patent number: 11230176
    Abstract: A battery system (10) for use on a vehicle electrical system (50) of a motor vehicle, comprising a negative pole (21), a positive pole (22), a battery module (5) and a switching unit (60) that has at least one actuatable switch and a current sensor (65) for measuring a battery current (IB) flowing through the battery system (10) is disclosed. The switching unit (60) is operable in a safety mode in which the at least one switch and the current sensor (65) interact such that the battery current (IB) is limited to a prescribed maximum value or is interrupted for a prescribed maximum period of time if the battery current (IB) exceeds a prescribed limit value and hence starting of the motor vehicle is prevented.
