PROBLEM TO BE SOLVED: To provide a non-contact power receiving device capable of surely protecting electrical equipment that is connected to a power receiving coil, from overvoltage.SOLUTION: The non-contact power receiving device includes a power receiving section 100, a battery 300, a non-contact battery charger 150, cutoff relays RY1 and RY2, a communication section 510 and a control section 500. The power receiving section 100 includes a power receiving coil 752 and receives power supplied from a power transmitting device 90. The non-contact battery charger 150 includes at least one of a rectifier, a converter and a filter and is provided between the power receiving section 100 and the battery 300. The cutoff relays RY1 and RY2 are provided between the non-contact battery charger 150 and the power receiving section 100. The control section 500 makes the communication section 510 transmit a signal requesting power transmission to the power transmitting device 90 with second power smaller than first power for charging the battery 300, and checks whether the cutoff relays RY1 and RY2 are welded while using a voltage receiving the second power transmitted from the power transmitting device 90 by means of the power receiving coil 752.
【課題】受電コイルに接続される電気機器を確実に過電圧から保護することが可能な非接触受電装置を提供する。【解決手段】非接触受電装置は、受電部100と、バッテリ300と、非接触充電器150と、遮断リレーRY1,RY2と、通信部510と、制御部500とを備える。受電部100は、受電コイル752を含み、送電装置90から供給される電力を受電する。非接触充電器150は、整流器、コンバータおよびフィルタの少なくとも1つを含み、受電部100とバッテリ300との間に設けられる。遮断リレーRY1,RY2は、非接触充電器150と受電部100との間に設けられる。制御部500は、バッテリ300に充電するための第1電力よりも小さい第2電力で送電装置90に送電を要求する信号を通信部510に送信させ、送電装置90から送電される第2電力を受電コイル752で受電した電圧を用いて遮断リレーRY1,RY2の溶着の有無をチェックする。【選択図】図1
