To secure detection accuracy of foreign object detection and of positioning between an electric power transmission unit and an electric power reception unit using a photographing device, in an electric power transmission system that uses the photographing device provided in an electric power transmission device to perform the foreign object detection and the positioning between the electric power transmission unit and the electric power reception unit.SOLUTION: An electric power transmission device 100 comprises an electric power transmission unit 110, a camera 120, and a first illuminant 122. An electric power receiving device 210 includes an electric power reception unit 212 and second illuminants 216, 217. The first illuminant 122 lights during performing of foreign object detection using a picture photographed with the camera 120. The second illuminants 216, 217 light and the first 122 illuminant turns off light during performing of positioning between the electric power transmission unit 110 and the electric power reception unit 212 using the picture photographed with the camera 120.SELECTED DRAWING: Figure 1
【課題】送電装置に設けられる撮影装置を用いて異物検知及び送電部と受電部との位置合わせを行なう電力伝送システムにおいて、撮影装置を用いた異物検知及び位置合わせの検出精度を確保する。【解決手段】送電装置100は、送電ユニット110と、カメラ120と、第1発光体122とを備える。受電装置210は、受電ユニット212と、第2発光体216,217とを含む。カメラ120により撮影される画像を用いた異物検知の実行中は、第1発光体122が点灯する。カメラ120により撮影される画像を用いた送電ユニット110と受電ユニット212との位置合わせの実行中は、第2発光体216,217が点灯し、かつ、第1発光体122は消灯する。【選択図】図1
