A power receiving device includes: a power receiving unit configured to wirelessly receive power from a power transmitting unit of a power transmitting device; a rectifier circuit; a charging relay provided between the rectifier circuit and the power storage device; a voltage sensor configured to sense a voltage applied from the power receiving unit to the rectifier circuit; and a charging ECU configured to wirelessly communicate with the power transmitting device via a communication device. After wireless communication with the power transmitting device is established before a power request is output to the power transmitting device, the charging ECU closes the charging relay and also performs a short-circuit determination process, by using a value of a voltage sensed by the voltage sensor with the charging relay closed, to determine whether the rectifier circuit has a short circuit fault.
