摘要： A fuel cell system that employs a recuperative heat exchanger to provide additional cooling for the compressed charge air applied to the cathodes of the fuel cells in the fuel cell stack. The cathode exhaust gas is applied to the recuperative heat exchanger so that the cathode exhaust gas cools the charge air heated by the compressed air. A cathode exhaust gas expander is provided in combination with the recuperative heat exchanger that uses the energy in the heated cathode exhaust gas to power the charge air compressor. An anode exhaust gas combustor can be provided that burns residual hydrogen in the anode exhaust gas to further heat the cathode exhaust gas before it is applied to the expander.

摘要： PROBLEM TO BE SOLVED: To provide a regenerative braking system and method for a batteryless fuel cell vehicle. SOLUTION: This system includes a fuel cell stack 106, a plurality of ancillary loads 134, and a regenerative braking device that is coupled to at least one wheel 104 of the vehicle. The regenerative braking device powers the ancillary loads when the vehicle coasts or brakes. The fuel cell powers the loads when the vehicle accelerates or at constant velocity. The regenerative braking device dissipates power in an air supply compressor 124 when the vehicle travels downhill to provide brake assistance. The compressor can be run at a high airflow and high pressure to create an artificially high load. A bypass value 128 is modulated to adjust the artificially high load of the compressor. A backpressure valve 126 protects the fuel cell stack from the high airflow and pressure. A controller 144 controls the brake torque of the regenerative braking device as a function of vehicle speed and modulates the bypass valve. COPYRIGHT: (C)2003,JPO

摘要： An inductive battery charging system (10) comprises a charge probe (16) and a charge port (22) and employs multi-turn spiral and helical windings (31a, 31b) in the charge probe (16) to provide improved thermal management of the power produced by the charging system (10). The thermal management provided by the multi-turn windings (31a) of the present invention improves the power handling capacity of the system and reduces AC proximity losses. Numerous flat helical and spiral transformer windings (31a, 31b) are disclosed that provide for differing thermal management schemes. The present invention may be used to increase the inductive charging capacity of electric vehicle propulsion batteries (25) to on the order of 120 KW. The present invention may be used with almost any transformer or inductor that uses foil windings.

摘要： A transmission cable system (10) is disclosed for use with an inductive charging system (11) that transfers electric power from a power source (12) to batteries (14) of an electric vehicle (15). The cable system (10) comprises a selected combination of different cooling systems (19, 20, 30) for cooling coolant (23) that flows through a cable (17), and a heating system (40) for heating the coolant (23) in low ambient temperature conditions. The transmission cable (17) is electrically coupled between the power source (12) and the electric vehicle (15) for coupling electrical power to the batteries (14). The transmission cable (17) is also coupled to the heating and cooling systems (19, 20, 30, 40) and the inductive charging system (11) by means of a plurality of coolant channels (35, 36) that permit the flow of the coolant (23) therethrough. The cooling systems (19, 20, 30) cool the cable (17) when transferring electrical power and the heating system (40) heats the coolant (23) in low temperature conditions to keep the cable (17) flexible and provides for more easily pumped coolant (23).

摘要： A charging system (40) employing a liquid-cooled transmission cable (20) for transferring power. The transmission cable (20) has a central tube (33) with an extruded member (31) disposed therewithin for carrying coolant (32). A plurality of layers (34) of coaxial tubular wire braid are disposed around the central tube (33) that carry charging current and that are separated by layers (35) of dielectric material. An outer layer (36) of wire braid is disposed around an outermost layer (35) of dielectric material that is used for grounding and/or shielding. An outer jacket (37) is disposed around the outer layer (36) of wire braid for encasing the transmission cable (20). The extruded member (31) may comprise a thermoplastic rubber extrusion, for example. The coolant path through the transmission cable is internally supported by means of the extruded member (31) to assure uniform flexibility, maintain tangential magnetic flux and eliminate kinking and collapse of the flow path. The transmission cable (20) is designed for charging propulsion batteries (29) of an electric vehicle (19) at extremely high charge rates. The charging system (40) includes an external power source (43) and an off-vehicle inverter (41) for providing charging current to the propulsion batteries (29) by way of a charge port (11) and a rectification/filter circuit (18) in the electric vehicle (19). The transmission cable (20) is coupled between the charge port (11) and the rectification/filter circuit (18). A cooling system (10) is coupled to the transmission cable (20) that has a radiator (12) for cooling coolant (32), a manifold (13), a pump (15) that pumps the coolant (32), and a reservoir (17) for storing excess coolant (32). The coolant (32) is pumped from the coolant system (10) through the transmission cable (20) to cool it. The transmission cable (20) is capable of transferring 120 kW @ 334 Amps RMS @ 75 KHz.
