PROBLEM TO BE SOLVED: To provide a noncontact charging system in which such a situation that during a period, where a vehicle moves at a low speed after wireless communication connection is established between a vehicle while driving and a power supply stand, and communication faults are likely to occur frequently, wireless communication connection between them is disconnected and charging is disabled can be avoided to the maximum.SOLUTION: A noncontact charging system 100 is constituted of power supply stands 10-30 installed, respectively, in the parking spaces in a parking area, and an electric car 40. The electric car 40 and the power supply stand 10 are configured so as to disconnect the wireless communication connection, when it is established between them, and reception of a signal from the opposite party fails by a predetermined communication disconnection times, and the predetermined communication disconnection times is set depending on the speed of the electric car 40.SELECTED DRAWING: Figure 4
【課題】走行中の車両と給電スタンドの間で無線通信接続が確立された後、車両が低速で移動して通信障害が多発しやすい期間中に、両者の間の無線通信接続が切断されて充電処理が行えなくなる事態を最大限回避することができる、非接触充電システムを提供する。【解決手段】非接触充電システム100は、駐車場内の各駐車スペースにそれぞれ設置される給電スタンド10〜30と電気自動車40とから構成されている。電気自動車40と給電スタンド10は、両者の間で無線通信接続を確立している際に、相手方からの信号の受信に所定の通信切断回数だけ失敗すると、無線通信接続を切断するように構成されており、所定の通信切断回数は電気自動車40のスピードに応じて設定される。【選択図】図4
