To increase the responsivity and reduce the amount of communication when a ground-side supply device and a travelling vehicle are communicating wirelessly with a server.SOLUTION: A wireless power transmission system includes: a supply device having a primary coil set in a road; a vehicle having a secondary coil for receiving electric power transmitted from the primary coil contactlessly; and a server connected to the supply device and the vehicle by a wide-range wireless communication. The supply device sends identification information of the supply device to the server before receiving a signal from the vehicle. The server sends a compatibility list formed of a combination of compatible supply devices and vehicles to the supply device on the basis of identification information of the supply device and information of the vehicle. The supply device performs paring with the vehicle on the basis of the compatibility list when a signal is received from the vehicle by a narrow-area wireless communication.SELECTED DRAWING: Figure 9
【課題】地上側の供給装置と走行中の車両とがそれぞれサーバとの間で無線通信する場合に応答性を高くできるとともに通信量を低減させること。【解決手段】道路に設置された一次コイルを有する供給装置と、一次コイルから非接触で伝送された電力を受け取る二次コイルを有する車両と、供給装置および車両と広域無線通信により通信可能に接続されるサーバと、を備えたワイヤレス電力伝送システムであって、供給装置は、狭域無線通信による車両からの信号を受信するよりも前に供給装置の識別情報をサーバに送信し、サーバは、供給装置の識別情報と車両の情報とに基づいて、互換性のある供給装置と車両との組み合わせからなる互換性リストを供給装置に送信し、供給装置は、狭域無線通信による車両からの信号を受信した場合に、互換性リストに基づいて車両とのペアリングを行う。【選択図】図9
