  • Patent number: 10286787
    Abstract: A mining haul truck driven by electrical wheel motors is operated with all electrical power sources; that is, without a diesel engine. While travelling on the loading site, the mining haul truck is powered by an on-board energy storage system, which can comprise a bank of ultracapacitors. The mining haul truck then moves to the bottom of a trolley ramp and is coupled to trolley lines. While travelling uphill, the mining haul truck is powered by the trolley lines, and the on-board energy storage system is charged by the trolley lines. When the mining haul truck reaches the top of the trolley ramp, the mining haul truck is uncoupled from the trolley lines. While travelling on the unloading site, the mining haul truck is powered by the on-board energy storage system. The on-board energy storage system can also be charged by retard energy generated by the wheel motors during braking.

  • Patent number: 10240322
    Abstract: An energy storage system associated with a machine having a work tool and one or more auxiliary loads includes a power source which generates mechanical power. An energy storage device supplies power to the one or more auxiliary loads. An electrical generator is operably coupled to the power source and converts at least a portion of the mechanical power into electrical power. The electrical generator supplies the electrical power to the energy storage device. A controller is communicably coupled to the power source, the work tool, the energy storage device, and the electrical generator. The controller determines a power demand of the work tool. The controller then compares whether the determined power demand exceeds a pre-determined threshold power. The controller disables the electrical generator from supplying the electrical power to the energy storage device if the power demand exceeds the pre-determined threshold power.

  • Patent number: 8534198
    Abstract: A locomotive includes an engine compartment having two sidewall structures and inboard and rear end structures defining an engine enclosure. A top hatch cover a top opening of the enclosure, which houses an engine. A removable cap being generally box-shaped extends across a portion of the top opening adjacent the top hatch and also across a portion of each of the two sidewall structures. An engine pit opening is exposed when removable cap is removed. The engine pit opening is sufficiently large to accommodate lifting the engine out of the enclosure. The engine pit opening is partially defined by two side edges extending parallel to the centerline along sidewall structures, each of the two side edges being disposed at a clearance height that is lower than an overall height of the engine compartment.

  • Patent number: 8511449
    Abstract: A propulsion system for a powered rail vehicle includes a fuel engine, an alternator, and a tractive circuit. The alternator is coupled with and driven by the engine to produce a fuel-based electric current. The tractive circuit includes a conductive bus coupled with the alternator and a traction motor. The conductive bus is configured to couple with a power conditioning circuit to receive an external electric current from an external electric power source via the power conditioning circuit. The tractive circuit has a fuel-powered only configuration, a fuel- and electric-powered configuration, and an electric-powered only configuration. The tractive circuit supplies the traction motor with the fuel-based electric current in the fuel-powered only configuration, with the fuel-based electric current or the external electric current in the fuel- or electric-powered configuration, and with the external electric current in the electric-powered only configuration.

  • Publication number: 20130190956
    Abstract: This invention provides a vehicle powered by a surface-mediated cell (SMC)-based power source, comprising a vehicle frame, at least a wheel supporting the frame or a propeller connected to the frame, a drive unit connected to the wheel or propeller, and a power source electrically connected to the drive unit, wherein the power source contains at least a surface-mediated cell. The vehicle can be a micro-EV (using the SMC for the stop-start function), HEV, plug-in HEV, all-electric vehicle, power-assisted bicycle, scooter, motorcycle, tricycle, automobile, wheelchair, fork lift, golf cart, specialty vehicle, bus, truck, train, rapid-transit vehicle, boat, or air vehicle. The ultra-high power density enables the SMC to provide pulsed power or increased current demands when the vehicle is accelerating or hill-climbing. The SMC also enables the power source to recuperate the braking energy when the vehicle decelerates, brakes, or simply moves down-hill.

  • Patent number: 8421266
    Abstract: A power distribution system for a rail vehicle includes a propulsion alternator, a first bus, a Head End Power (HEP) alternator, and a second bus. The propulsion alternator is joined to an engine of the rail vehicle. The first bus is joined with the propulsion alternator and is configured to electrically couple the propulsion alternator with a propulsion electric load that propels the rail vehicle. The HEP alternator is joined to the engine. The second bus is joined with the HEP alternator and is adapted to electrically couple the HEP alternator with a non-propulsion electric load of the rail vehicle. The propulsion alternator generates a first electric current to power the propulsion electric load and the HEP alternator separately generates second electric current to power the non-propulsion electric load. The HEP alternator and the second bus are electrically separate from the propulsion alternator and the first bus.
