Abstract: Apparatuses, systems, and methods for transferring electrical power between an electrical power system of a vehicle and another device. In an illustrative embodiment, an apparatus includes a wireless transfer unit electrically coupled with a high voltage system of a vehicle and configured to enable wireless bidirectional power exchange between the high voltage system and an auxiliary device. The high voltage system is operable to power a drivetrain of the vehicle and the auxiliary device is separate from the vehicle and configured to at least one of provide electric power to and receive power from the high voltage system. A transfer control unit is configured to communicate with the wireless transfer unit and control at least one parameter specifying a transfer of electrical power between the high voltage system and the auxiliary device.

Abstract: The invention relates to a method for switching off a fuel cell system (100) having a fuel cell stack (10), that has anode chambers (13) and cathode chambers (12), and a cathode supply (20) having a cathode supply path (21) for supplying an oxygenated cathode operating gas into the cathode chambers (12), a compressor (23) arranged in the cathode supply path (21) and a cathode exhaust path (22) for discharging a cathode exhaust gas from the cathode chambers (12). The method comprises the steps of: (a) Maintenance of the cathode chambers (12) under excess pressure while preventing a flow of cathode operating gas through the cathode chambers (12) while keeping the cathode operating gas that is present in the cathode chambers (12) oxygen-depleted; (b) Expansion of the oxygen-depleted cathode operating gas present in the cathode chambers (12) via the cathode supply path (31) [sic] and/or the cathode exhaust path (22), and (c) Separation of the cathode chambers (12) from the environment.

Abstract: A method for operating a fuel cell device, the fuel cell device having a fuel cell, and a motor vehicle having a drive system and the fuel cell device are disclosed. In order to avoid energy which has been made available by the fuel cell device being used merely to heat the fuel cell and therefore not being available for a consumer, there is provision according to the invention that the energy to be stored is limited as a function of the ambient temperature and the fuel cell device has for this purpose an ambient temperature-determining unit and a charge limiter which is connected to the ambient temperature-determining unit in a control signal-transmitting fashion.
