Abstract: A contactless power feeding apparatus includes a plurality of primary coils mounted on a road and a power feed controller which uses a portion of the primary coils as a power transmitting coil to achieve delivery of electrical power from the power transmitting coil to a secondary coil mounted in a vehicle. The power feed controller uses a selected primary coil that is one of the primary coils other than the power transmitting coil to decrease a leakage of magnetic flux arising from excitation of the power transmitting coil. Instead of the selected primary coil, the secondary coil may be used to reduce the leakage of magnetic flux.

Abstract: A battery charger of a battery charging apparatus is disposed on an exterior case of an engine in such a manner that a generated heat is transferred therebetween. An ECU drives a cooling system when an engine temperature and temperature of the battery charger satisfy a predetermined cooling temperature condition. A cooling capacity for cooling the battery charger is improved by establishing a heat radiation passage to radiate a heat from the battery charger efficiently.

Abstract: A contactless feeding pad includes a power-receiving side pad, a power-transmitting side pad, and an auxiliary pad. The power-transmitting side pad is different from the power-receiving side pad in size or shape and transmits electric power contactlessly to the power-receiving side pad while being situated oppositely to the power-receiving side pad. The auxiliary pad is installed between the power-transmitting side pad and the power-receiving side pad in close proximity to the power-transmitting side pad or the power-receiving side pad and forms a resonance circuit.
