To provide a system that can appropriately control a period of temporary suspension of electric power transmission of an electric power transmission unit when the presence of a foreign object is detected around the electric power transmission unit.SOLUTION: Electric power transmission by an electric power transmission unit 10 to an electric power receiving unit 20 and thus contactless charging of a battery 200 installed in a vehicle 2 is temporarily suspended on a condition that the presence of a foreign object is detected around the electric power transmission unit 10. In addition, a specified period T, which is a period of temporary suspension of electric power transmission of the electric power transmission unit 10, is differentiated in accordance with a type of foreign object, in this embodiment, a metal or an object containing a metal (first foreign object) and a living body (second foreign object).SELECTED DRAWING: Figure 1
【課題】送電ユニットの周囲において異物の存在が検知された場合の、当該送電ユニットの送電の一時停止期間を適当に制御しうるシステムを提供する。【解決手段】送電ユニット10の周囲において異物の存在が検知されたことを要件として、当該送電ユニット10の受電ユニット20への送電、ひいては車両2に搭載されているバッテリ200の非接触充電が一時停止される。また、送電ユニット10の送電の一時停止期間である指定期間Tが、異物の種類、本実施形態では、金属または金属を含む物体(第1異物)および生体(第2異物)の別に応じて差異化される。【選択図】図1
