ELECTRIC VEHICLE HAVING MULTIPLE-USE APU SYSTEM

During periods of vehicle inactivity, a vehicle-based APU electric generating system may be coupled into a regional electric grid to send electricity into the grid. A currently-preferred APU is a solid oxide fuel cell system. When a large number of vehicles are thus equipped and connected, substanti...

Zusammenfassung:	During periods of vehicle inactivity, a vehicle-based APU electric generating system may be coupled into a regional electric grid to send electricity into the grid. A currently-preferred APU is a solid oxide fuel cell system. When a large number of vehicles are thus equipped and connected, substantial electric buffering can be effected to the grid load. A vehicle-based APU can also function as a back-up generator to a docking facility in the event of power failure of the grid. Gaseous hydrocarbon is readily supplied by pipe in many locations as a commercial and residential heating fuel source, and a hydrocarbon reformer on the vehicle can be attached to the fuel source, enabling an APU to operate as a stationary power source indefinitely. An optional storage tank on the vehicle may be refueled with gaseous fuel, for example, while the battery is being electrically recharged by the grid.
