Claim 21:
22. An electric vehicle, comprising:
a device adapted to supply a first load of an electric vehicle with a first DC voltage and to supply a second load with a second DC voltage, including:
a first energy storage device adapted to supply the first DC voltage;
a second energy storage device adapted to supply the second DC voltage;
an energy supply unit adapted to supply an output DC voltage, the first energy storage device being connected via a converter device to the energy supply unit, the second energy storage device being connected to the energy supply unit;
wherein the converter device is adapted to convert the output DC voltage into the first DC voltage;
wherein the device is adapted to prevent a first power flow from the first energy storage device to the second energy storage device and to prevent a second power flow from the second energy storage device to the first energy storage device;

an electrical drive device adapted to drive the vehicle; and
a control device adapted to control driving movement of the vehicle;
wherein the first energy storage device is adapted to supply the control device with the first DC voltage, and the second energy storage device is adapted to supply the drive device with the second DC voltage; and
wherein the electric vehicle is adapted to perform a method including:
preventing the first power flow from the first energy storage device to the second energy storage device; and
preventing the second power flow from the second energy storage device to the first energy storage device.
