Abstract
A switching arrangement for discharging an energy storage device of a motor vehicle including an energy storage device that stores electrical energy and supplies an electrical machine of a motor vehicle, a discharging circuit having a discharging resistor, a voltage comparison element and an activation switching device. The activation switching device starts discharging the energy storage device via the discharging resistor at the end of a delay period after the motor vehicle has been switched off. The voltage comparison element compares the prevailing voltage of an energy storage voltage and a voltage threshold value and terminates the procedure of discharging the energy storage device if the prevailing voltage of the energy storage device is less than or equal to the voltage threshold value.
