The invention provides a non-contact power supply system, a ground power supply device and a vehicle. A shift occurring in the relative position between a power transmitting device and a power receiving device is detected using short-range communication. A non-contact power supply system (1) performs non-contact power transmission between a ground power supply device (2) and a vehicle (3) by magnetic field resonance coupling. The vehicle has a power receiving-side resonant circuit (51) for receiving power and a signal transmission device for transmitting an alternating-current magnetic field or a radio wave for transmitting vehicle identification information of the vehicle to a ground power supply device. The ground power supply device has a power transmission-side resonance circuit (43) for transmitting power to the power reception-side resonance circuit, and a signal reception device for receiving the alternating-current magnetic field or radio wave transmitted from the signal transmission device. The ground power supply device detects the relative positional relationship between the power transmission-side resonance circuit and the power reception-side resonance circuit on the basis of the intensity of the alternating-current magnetic field or radio wave received by the signal reception device.
本发明提供非接触供电系统、地上供电装置及车辆。使用短程通信来检测送电装置与受电装置之间的相对位置产生的偏移。非接触供电系统(1)在地上供电装置(2)与车辆(3)之间进行基于磁场谐振耦合的非接触电力传输。车辆具有进行受电的受电侧谐振电路(51)和发送用于将车辆的车辆识别信息向地上供电装置发送的交流磁场或电波的信号发送装置。地上供电装置具有进行向受电侧谐振电路的送电的送电侧谐振电路(43)和接收从信号发送装置发送出的交流磁场或电波的信号接收装置。地上供电装置基于信号接收装置接收到的交流磁场或电波的强度来检测送电侧谐振电路与上述受电侧谐振电路之间的相对位置关系。
