To provide a contactless charging system that can suppress a decrease in charging efficiency, overcurrent, and overvoltage without changing the configuration of a power transmission device and a power receiving device even when batteries of vehicles with different vehicle heights are charged.SOLUTION: A contactless charging system includes a power transmission device that transmits power to be supplied by a power transmission coil, a power receiving device that receives the power transmitted by the power transmission coil with a power receiving coil, and a relay device that is placed between the power transmission device and the power receiving device and relays the power transmitted by the power transmission coil with the relay coil. The area of the coil surface of the relay coil of the relay device provided in this contactless charging system is determined according to the vehicle height of a vehicle.SELECTED DRAWING: Figure 3
【課題】車高の異なる車両のバッテリを充電する場合であっても、送電装置及び受電装置の構成を変えることなく、充電効率の低下や過電流、過電圧を抑制することが可能な非接触充電システムを提供する。【解決手段】この非接触充電システムは、給電される電力を送電コイルで送電する送電装置と、送電コイルにより送電される電力を受電コイルで受電する受電装置と、送電装置と受電装置の間に配置され送電コイルにより送電される電力を中継コイルで中継する中継装置とを備える。この非接触充電システムに備える中継装置の中継コイルは、車両の車高に応じてコイル面の面積が定められている。【選択図】図3
