A system for wireless power transfer of on-road vehicles is provided herein. The system includes a plurality of base stations; a power transmission line located beneath a surface of a road having a plurality of segments, each segment having at least one pair of coils and at least one capacitor electrically connected via a switch to the coils in the segment; and at least one vehicle having at least one power receiving segment having at least two coils, connected to at least one capacitor, wherein the at least one vehicle further includes a communication transmitter configured to transmit a power requesting signal, wherein the coils of the power transmitting segment are configured to receive the power requesting signal; and wherein each of the base stations is further configured to feed a plurality of the power transmitting segments with current at a resonance frequency, responsive to the power requesting signal.

A charging system includes a vehicle and a charging device. The vehicle includes a power storage functional unit, a driving unit, a power reception unit, a charge controller, a third communication unit, and a fourth communication unit. The charge controller charges the power storage functional unit with electric power received by the power reception unit. The third communication unit performs wireless communication with a first communication unit positioned in a first range smaller than a predetermined region based on the vehicle, and receives an identifier. The fourth communication unit transmits instruction information to a second communication unit of the charging device that is identified with the identifier received by the third communication unit, the second communication unit being positioned in a second range larger than the first range based on the vehicle.

A method of locating an electric vehicle at a charging station having multiple chargers is includes, receiving at multiple fixed transceivers positioned at different locations in the charging station, signals from the electric vehicle as the electric vehicle moves in the charging station, and determining, at a controller, a current location of the electric vehicle in the charging station using the signals received by the multiple fixed transceivers.

A mobile body is driven by power that is wirelessly transferred from a non-contact power supply device including a power transmission resonator that transmits power in accordance with a non-contact power supply method. The mobile body includes a power reception resonator, a power storage, a motor, a controller, and at least two wheels driven independently of each other by the motor, the at least two wheels including a first movement axis and a second movement axis with an axial orientation different from that of the first movement axis, and moving the mobile body along the first movement axis and the second movement axis. When the mobile body moves to a power supply target range, the controller controls the motor based on power reception status information indicating a status of power reception by the power reception resonator, and moves in a flat plane direction.
