Electrical powered vehicle and power feeding device for vehicle

摘要

An electrical powered vehicle includes a secondary self-resonant coil, a secondary coil, a rectifier, and a power storage device. The secondary self-resonant coil is configured to be magnetically coupled with a primary self-resonant coil of a power feeding device by magnetic field resonance, and allow reception of high frequency power from the primary self-resonant coil. The secondary coil is configured to allow reception of electric power from the secondary self-resonant coil by electromagnetic induction. The rectifier rectifies the electric power received by the secondary coil. The power storage device stores the electric power rectified by the rectifier.

1. A power feeding device for an electrical powered vehicle, comprising:
a high frequency power driver configured to convert electric power received from a power source into high frequency power, a transmitting coil configured to be magnetically coupled with a receiving coil mounted on said vehicle by a magnetic field, and to transmit said high frequency power received from said high frequency power driver, and a reflective wall formed at a rear side of said transmitting coil with respect to a power transferring direction from said transmitting coil, to allow reflection of a magnetic flux output from said transmitting coil in said power transferring direction, the transmitting coil and the reflective wall being arranged spaced apart from each other.
