VEHICLE COMPRISING A STANDBY POWER SUPPLY DEVICE AND METHOD FOR OPERATING SAME

A vehicle includes a converter with a connection on the input side for a vehicle-integrated or vehicle-external supply network and which can generate a DC voltage on the output side; and an internal DC network which can be operated using the DC voltage of the converter. A standby power supply device is connected between the converter and the internal DC network. The input voltage of the standby power supply device is formed directly or indirectly by the DC voltage of the converter and the standby power supply device feeds its input voltage or alternatively an auxiliary operating voltage supplied by a stored energy source into the internal DC network as output voltage. The vehicle has a monitoring device which is configured to process at least three control signals.
