To provide a system capable of shortening a charging period of a battery even when the presence of a foreign substance is detected when the battery mounted on the vehicle is charged by a non-contact method.SOLUTION: When a battery 200 mounted on a vehicle 2 is non-contact charged, the power transmission amount P of a power transmission unit 10 is reduced in response to the detection of the presence and type of foreign matter that interferes with the power transmission around a power transmission unit 10, and the reduced amount is controlled according to the type of foreign matter. Even in a case in which the power transmission amount P of the power transmission unit 10 is reduced, before a use start time of the vehicle 2 or before a predetermined period elapses from the use start time of the vehicle 2, when it is predicted that the battery 200 mounted on the vehicle 2 is completely charged, a notification prompting the removal of the foreign matter is omitted.SELECTED DRAWING: Figure 3

    【課題】非接触方式で車両に搭載されているバッテリが充電される際、異物の存在が検知された場合でも当該バッテリの充電所要期間の短縮を図りうるシステムを提供する。【解決手段】車両2に搭載されているバッテリ200が非接触充電されている際に、送電ユニット10の周囲に送電の障害となる異物の存在および種類が検知されたことに応じて、当該送電ユニット10の送電量Pを低減させ、かつ、当該低減量が異物の種類の別に応じて制御される。送電ユニット10の送電量Pが低減されても、車両2の使用開始時刻の前、または、車両2の使用開始時刻から所定期間が経過する前に、車両2に搭載されているバッテリ200の充電が終了すると予測される場合、あえて異物の除去を促す通知が省略される。【選択図】図3
