The power reception device includes a power reception unit configured to receive power from a power transmission unit, a power storage device, a charging relay provided between the power reception unit and the power storage device, and a controller. The controller executes a first fail-safe control when a malfunction is detected during external charging in which the charging relay is switched to the ON state. In the first fail-safe control, an output power of the power transmission unit is reduced lower than a target value with the charging relay being maintained at the ON state, the output power is restored to the target value if the malfunction is solved before a standby time has passed, and the charging relay is switched to the OFF state so as to stop the external charging if the malfunction is not solved after the standby time has passed.
