Abstract: A wireless power transfer system comprises: a power conversion unit generating power to be transmitted to a power reception coil; a power transmission unit group constituted by two or more power transmission units, each power transmission unit having a power transmission circuit including a power transmission coil; a control unit controlling supply of power from the power conversion unit to the power transmission unit group; and a position detection unit detecting a position of a mobile body. The control unit, based on position information, supplies power from the power conversion unit to a power transmission unit group that satisfies a power transmission condition including that a distance of the power transmission coil relative to the power reception coil of the mobile body is less than or equal to a predetermined threshold, and does not supply power to a power transmission unit group that does not satisfy the power transmission condition.

Abstract: A control apparatus for a power receiver which wirelessly receives electric power from a power transmitter. The control apparatus being configured to execute a restriction process that restricts received power by PWM control depending on an amount of the received power. The restriction process comprises calculating an increase gap which is a difference between an initial received power and a local maximum value of the received power with respect to a change in a duty in the PWM control, starting the PWM control when a first value which is a value obtained by adding the increase gap to a current received power exceeds a second value which is a value obtained by subtracting a predetermined margin from an upper limit of the received power, and increasing the duty until the received power becomes lower than the initial received power when starting the PWM control.

Abstract: 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.

Abstract: A plurality of power feed mats are stored as being distributed at a plurality of storage locations, and each of the plurality of power feed mats is configured to supply electric power to a movable body. A server includes a memory and a processor. Data in which an identification number, a type, and a storage location of each of the plurality of power feed mats are associated with one another is stored in the memory. The processor determines at least one power feed mat to be rented based on the data, in response to an inquiry from a user. The processor determines a storage location to be a source of rental or a storage location to be a return destination such that inventory of a plurality of types of power feed mats is ensured at each of the plurality of storage locations.

Abstract: An ECU controls a vehicle including a power reception unit that can wirelessly receive electric power from a power feeding facility placed on a travel road. The ECU includes a memory in which a user-desired condition is stored, the user-desired condition being a condition under which a user of the vehicle desires on-road power reception, the on-road power reception being power reception from the power feeding facility placed on the travel road, and a processor connected to the memory. When a physical condition for power feeding from the power feeding facility to the vehicle is satisfied and when the user-desired condition stored in the memory is not satisfied, the processor controls the power reception unit to suppress on-road power reception.

Abstract: A noncontact power supplying system transfers power by noncontact between a ground power supplying apparatus and a vehicle. The vehicle includes a power reception side resonance circuit for receiving power, and a signal emitting device for emitting an alternating magnetic field or electric wave for transmitting vehicle identification information of the vehicle to the ground power supplying apparatus. The ground power supplying apparatus includes a power transmission side resonance circuit for transmitting power to the power reception side resonance circuit, and a signal reception device for receiving an alternating magnetic field or electric wave emitted from the signal emitting device. The ground power supplying apparatus detects a relative positional relationship between the power transmission side resonance circuit and the power reception side resonance circuit, based on the strength of the alternating magnetic field or electric wave which the signal reception device receives.
