Claim:
1. A transfer device for transferring electrical energy in a motor vehicle, the transfer device comprising: a first sampling device configured to determine whether a first energy store of a first vehicle electrical distribution system and a second energy store of a second vehicle electrical distribution system have been filled sufficiently; a second sampling device configured to detect whether electrical energy is being withdrawn from one of the first and second vehicle electrical distribution systems; a DC-to-DC converter configured to transfer electrical energy between the vehicle electrical distribution systems; and a control device configured to operate in an automatic mode to control a transfer of electrical energy; wherein, based on signals from the second sampling device indicating that electrical energy is being withdrawn from the second vehicle electrical distribution system, the control device is configured to control the transfer of electrical energy from the first vehicle electrical distribution system to the second vehicle electrical distribution system; and wherein, based on signals from the second sampling device indicating that electrical energy is being withdrawn from the first vehicle electrical distribution system, the control device is configured to control the transfer of electrical energy from the second vehicle electrical distribution system to the first vehicle electrical distribution system.
