Patent ID: 8421409

Claim:
A noncontact power receiving apparatus for an electrically-powered vehicle, receiving electric power from a power transmission coil transmitting the electric power received from a power supply, the noncontact power receiving apparatus comprising: a power reception coil configured to receive electric power transmitted from the power transmission coil; a rectifier configured to rectify the electric power received by the power reception coil; a power storage device configured to receive the electric power rectified by the rectifier; a first relay provided on a path between the power reception coil and the rectifier; a second relay provided on a path between the rectifier and the power storage device; and a control unit configured to perform a cutoff confirming operation of the first relay after performing a cutoff confirming operation of the second relay, wherein the cutoff confirming operation of the second relay includes detecting a voltage on a power transmission path connecting the rectifier and the second relay while commanding the second relay to cut off, and the cutoff confirming operation of the first relay includes detecting a voltage on a power transmission path connecting the rectifier and the first relay while commanding the first relay to cut off.
