A power supply system and method for a vehicle movable within a structure is provided. The power supply system includes at least one energy source arranged at a fixed location within the structure to transmit energy within the structure, and a receiver, arranged on the vehicle to receive the energy transmitted from the energy source, being configured to convert the energy to electrical power and/or thrust.

A power supply system can be used for an electric motor that drives a hydraulic pump in a demolition robot. The system provides a DC current from a source of power, controls and monitors the voltage level (VDCnom) of the DC current, can be activated, and supplies a pre-determined load current (I.sub.L) from the source of power to the electric motor. In order to offer improved operational availability and flexibility, the load current (I.sub.L) can be constituted by a DC current, and the electric motor can be a DC motor.

A dynamic wireless power transfer system performs, through a plurality of primary coils installed along a traveling direction of a road and a secondary coil mounted in a vehicle, power transfer to the vehicle while the vehicle is traveling. The secondary coil is an M-phase coil including M coils, M denoting an integer which is two or higher. The M coils each include a coil end extending along a front-rear direction of the vehicle and a main coil portion extending along a width direction of the vehicle, the M coils each being configured such that a magnetic resistance of a magnetic path where a magnetic flux of the coil end passes is higher than a magnetic resistance of a magnetic path where a magnetic flux of the main coil portion passes.

A driving assistance apparatus includes an information acquiring unit and a determining unit. The information acquiring unit is configured to acquire a target value of a power storage amount in an onboard battery mounted on a vehicle. The determining unit is configured to determine one or more charging implementation lanes out of charging lanes that are traveling lanes provided on a travel route of the vehicle to an expected arrival location, apart from each other along a direction of the travel route, and configured to charge the onboard battery while the vehicle is traveling. The one or more charging implementation lanes are part of the charging lanes to implement charging of the onboard battery. The determining unit is configured to determine, on the basis of the target value of the power storage amount, the one or more charging implementation lanes to minimize a number of times of the charging of the onboard battery.

A power supply system supplies power from a moving body including a battery and an electric drive source to an external power supply target. The power supply system includes a DC-DC converter circuit provided in an internal power feeding path between the battery and the electric drive source, a connection circuit capable of electrically connecting the DC-DC converter circuit to a power receiving terminal (power supply inlet) of the power supply target, and a control device for controlling the DC-DC converter circuit so as to supply surplus power of the battery to the power supply target via the DC-DC converter circuit and the connection circuit.

An electrically driven, movable underground vehicle and a method for operating the same, includes a chassis with at least two driven drive wheels, an electrical trailing cable for connection to an electrical supply network, an electric drive motor, which is electrically connected to the trailing cable, for driving the drive wheels, and an energy storage unit. The vehicle further includes an auxiliary drive motor with a subsequent hydraulic fluid transmission, a switchgear assembly and a processor for controlling the supply of the electric drive motor and the electric auxiliary drive motor with electrical energy. The drive motor directly drives the drive wheels while bypassing the hydraulic fluid transmission. Also, the energy provided by the energy storage unit is sufficient for driving the drive wheels and for temporarily moving the load-haul-dump machine independently of the supply network.

A method is provided, which includes receiving, at a server, a request from a device to find one or more charge units for charging an electric vehicle at a geographic location. The method includes accessing, by the server, a first database to identify charge units that are associated with the geographic location. The method includes accessing, by the server, a second database to identify discounts available at the charge units identified to be associated with the geographic location. One of the identified discounts on one of the charge units is provided by a first merchant having a business location proximate to the one of the charge units. The method includes sending, by the server, data to the device that identifies one or more of the charge units that are associated with the geographic location, the data further including information regarding one or more discounts identified to be available at one or more of the identified charge units.
