Abstract
A motor vehicle has a plurality of electric consuming devices and a power supply system for supplying the electric consuming devices with electric energy. The power supply system has a decentralized construction and, for supplying electric energy to at least one electric consuming device or to a group of electric consuming devices, has a fuel cell system which is electrically isolated from other power sources and which is arranged in the proximity to the assigned consuming device or group of consuming devices. The decentralized construction may have many mutually independent fuel cell systems, permitting a high-efficiency power supply.
Claims14
A decentralized power supply system for a vehicle, comprising at least one fuel cell system and other power generators, wherein:
- in normal operation of the power supply system, the at least one fuel cell system is electrically isolated from the other power generators of the power supply system, is dedicated to supplying electricity to an assigned electric consuming device that is incorporated in a structural subassembly of the vehicle, and is an exclusive source of electric power supply to said assigned electric consuming device;
- and
- the at least one fuel cell system is collocated with the assigned electric consuming device, and is mounted on or in said structural subassembly of the vehicle.
A power supply system for an electric consuming device in a motor vehicle, comprising:
- a dedicated fuel cell system which, in normal operation of said power supply system, is connected as an exclusive supply of electric power to said consuming device;
- wherein
- in normal operation of said power supply system, said fuel cell system is electrically isolated from other power generators in said vehicle;
- and
- said fuel cell system is collocated with said electric consuming device, in a structural component of the vehicle.
Motor vehicle apparatus comprising:
- a component part which is mountable to a motor vehicle body;
- an electrically actuated device which is mounted on or in said component part;
- and
- a fuel cell system which is isolated and self contained and is mounted on or in said component part, collocated with said electrically actuated device, and is a dedicated and exclusive source of electric power supply to operate said electrically actuated device;
- wherein the component part is one of a vehicle door and a vehicle seat.
A power supply system for a vehicle having a plurality of power consumers disposed in subassemblies of said vehicle, said power supply system comprising:
- a plurality of individual power sources which, in normal operation of said power supply system, are electrically isolated and spatially separated from each other;
- wherein
- each of said individual power sources is connected as an exclusive source of electric power supply to a respective group of consumers, which are associated therewith;
- and
- each group of consumers is separately located in a different respective vehicle subassembly and is electrically isolated from other groups of consumers;
- each of said individual power sources is collocated with the group of consumers with which it is associated, within the same vehicle subassembly which contains said group of consumers with which it is associated;
- and
- said power sources comprise fuel cell units.
