  • Patent number: 7112891
    Abstract: The present invention is a mobile-energy generating system. It comprises a turbine, a fuel cell, commercial electrical power hookups, capacitors used for bridging purposes, and hydrogen-storage tanks. Pressurized hydrogen is maintained in the tanks using a hydrogen liberator which is optionally powered by a solar panel.

  • Patent number: 6124645
    Abstract: A hill-holding arrangement for an electrically driven vehicle includes a vehicle with a "gas pedal" which generates a torque command signal T.sub.CMD. A switch (314) couples T.sub.CMD to a motor controller (316, 14) which drives the motor (40) and therefore the vehicle. When the "gas pedal" calls for zero torque, and the vehicle speed is zero, the switch responds to logic (FIG. 5), and substitutes a position-holding torque command signal T.sub..theta. for the operator-controlled torque command signal T.sub.CMD. Position controlling torque command T.sub..theta. is generated by a controller (312) which receives a position signal representative of the angular position .theta. of the rotor. The position-holding torque control loop then produces such torque as may be required to prevent the rotor of the motor from moving from its commanded position.

  • Patent number: 4459489
    Abstract: A voltage regulating system for a generator that supplies the battery and electrical loads on a motor vehicle. The system includes a load response control for detecting whenever a substantial electrical load is applied to the generator tending to cause a drop in generator output voltage and when such a condition is detected field current is controlled to gradually increase field current from some value. The load response control includes means for storing an electrical signal that corresponds to generator field current and for utilizing this stored value to set generator field current at a value corresponding to a field current that occurred just prior to the detected drop in voltage and then increasing field current slowly from this value.

  • Patent number: 4119861
    Abstract: A starting apparatus for a gas turbine-generator mounted on an electric motor driven motorcar includes a gas turbine and an A.C. generator with A.C. output terminals coupled directly to the turbine. A rectifier with D.C. output terminals is connected to the A.C. output terminals of the A.C. generator. A battery device is connected to the D.C. output terminals of the rectifier. An inverter has D.C. input terminals connected to the floating battery device in parallel and A.C. output terminals from which an A.C. output is derived. A control circuit is connected to the inverter for controlling the speed of the motorcar. At least one A.C. motor energized by the A.C. output of the inverter for driving the motorcar is provided. A switching device connects the A.C. output terminals of the inverter to the A.C. output terminals of the A.C. generator when the gas turbine is started and connects the A.C. output terminals to the A.C. input terminals of the A.C. motor after the gas turbine is started.

  • Patent number: 4042056
    Abstract: A gasoline and battery-powered electric automobile wherein the start and the running of the car are effected by an electric motor except in circumstances where the battery charge is depleted, in which case the normal cruising and higher speeds are then obtained using a gasoline or internal combustion engine which can be cut in either automatically or at will. The electric motor is powered by storage batteries that can be recharged from a generator driven by the internal combustion engine, or else from house current. One pair of wheels of the vehicle is powered by the internal combustion engine through a magnetic clutch and differential. The other set of wheels is powered through an infinitely variable mechanical transmission comprising cone pulleys or cone chains whose ratio is power-controlled in accordance with the driver's desires or else with the speed of the vehicle.
