Abstract

A battery system for an electric vehicle has a high-voltage battery, a control unit, and a safety device for disconnecting the high-voltage battery from a high-voltage on-board electrical system of the electric vehicle. The battery system is characterized in that the control unit has two conductor loops, and that the control unit carries out a monitoring of the two conductor loops. Based on the monitoring, the control unit activates the safety device such that the safety device separates the high-voltage battery from the high-voltage vehicle electrical system of the electric vehicle, wherein the safety device has an irreversible separating element.
