摘要： A method including detecting that a vehicle that may be propelled by an electric drive system having one or more motors disconnects or begins disconnecting from an off-board source of power while the one or more motors are being powered by the off-board source of power. The method may include supplanting a decreasing amount of a first electric energy supplied by the off-board source of power to the electric drive system with an amount of a second electric energy supplied by an onboard source of power to the electric drive system responsive to the detection of the disconnect from the off-board source of power.

摘要： A contactless power feed system includes a first ground power feed device and a second ground power feed device for performing contactless power feed to a moving body. The first ground power feed device transmits a passing signal to the second ground power feed device when entry of the moving body to a first power feed section is confirmed. The second ground power feed device transmits a power feed stop signal to the first ground power feed device when confirmation of entry or approach of the moving body to a second power feed section is not possible even after a predetermined time has elapsed after receiving the passing signal.

摘要： A control system can include a controller that may obtain a location of a phase break along a route. The controller can monitor locations of a vehicle and determine when the vehicle will reach the phase break location. The system also may include a switch proximate to a collector device of the vehicle and/or an actuator that moves the collector device relative to a conductive pathway. The conductive pathway may operate to supply electrical power to the vehicle. The controller can actuate a switch, an actuator, or both the switch and the actuator, and (upon activation) can change a source of power for one or more loads for propulsion of the vehicle through the location of the phase break along the route.

摘要： A method for a dynamic inductive wireless power transmission includes providing an AC/DC power converter that receives three-phase power and provides regulated DC output current, connecting a trunk cable to the AC/DC power converter output and to multiple power transmitter modules. The trunk cable connects inputs of the power transmitter modules in series. The power transmitter modules transmit inductive wireless power over an air gap. The method includes providing a system controller that detects a vehicle containing a receiver coil and confirms if the vehicle should receive the inductive wireless power from the multiple power transmitter modules, and includes configuring the system controller to communicate with the AC/DC power converter to maintain the regulated DC output current at a constant value and transmit the inductive wireless power to the vehicle through the multiple power transmitter modules when the vehicle should receive the inductive wireless power.

摘要： A roadway powered electric vehicle system includes a power supply (101) which makes power available inductively to one or more modules (111) provided in or under a roadway. Modules (111) make a magnetic field selectively available to one or more vehicles travelling over the roadway corresponding to the location of the vehicle. The presence or strength of the magnetic field provided on the roadway may be dependent upon the vehicle type or category.

摘要： 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 may include 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 may also be charged by retard energy generated by the wheel motors during braking.
