Abstract
The invention relates to a method and a device for a motor vehicle having a current/voltage supply unit, in particular a fuel cell unit and/or a battery, with the current/voltage supply unit being necessarily discharged, when it is switched off, through a control and/or distribution unit or a temperature-dependent resistor.

-10. (canceled)
A method for operating an electrically driven motor vehicle having a current/voltage supply unit, wherein:
- electrical energy which is present when the current/voltage supply unit is switched off is consumed by one of (i) a control and/or distribution unit of the motor vehicle, and an electrical circuit which is associated with said control and/or distribution unit, and (ii) a temperature-dependent resistor;
- and
- said consuming is continued until at least one lower voltage limit is undershot.
Electrical energy supply apparatus for a motor vehicle, comprising:
- a first current/voltage supply unit;
- and
- means for discharging electrical energy which remains at an output of said first current/voltage supply unit, until a voltage at said output falls below a preset value;
- wherein said means for discharging comprises a temperature dependent resistor coupled to said output of said first current/voltage supply unit.
