비접촉 급전 시스템(10)은, 송전부(220)로부터 수전부(110)에 비접촉으로 전력을 공급하는 것이 가능하다. 비접촉 급전 시스템은, 대기 위치와 송전부와 대향하는 수전 위치의 사이에서 수전부를 이동시키는 승강 기구(105)와, 승강 기구를 제어하기 위한 ECU(300)를 구비한다. ECU는, 수전 위치로 수전부를 이동한 후이며 송전부로부터의 전력을 수전하고 있는 동안에, 수전 개시시에 비해 송전부와 수전부의 사이의 거리가 커진 경우에는, 이동 장치를 동작시켜 수전부를 송전부에 가까이한다. 이것에 의해, 송전부와 수전부의 사이의 거리가 변동함으로써 생기는 송전 중의 전력 전송 효율의 저하를 억제한다.

    A contactless power feeding system is configured to supply power from a power transmission unit to a power reception unit in a contactless manner. The contactless power feeding system includes a raising and lowering mechanism that moves the power reception unit between a standby position and a power reception position facing the power transmission unit, and an ECU for controlling the raising and lowering mechanism. After the power reception unit has been moved to the power reception position and during reception of power from the power transmission unit, when a distance between the power transmission unit and the power reception unit becomes greater than the distance at a start of the reception of power, the ECU operates the moving device to bring the power reception unit closer to the power transmission unit. Consequently, a reduction in power transfer efficiency during power transmission can be prevented.
