To provide a ground power supply device having a plurality of power transmission devices that controls each power transmission device based on information transmitted from a vehicle.SOLUTION: A ground power supply device 2 for transmitting power to a vehicle 3 without contact includes: a plurality of power transmission devices 4 that transmit power to the vehicle; at least one detection device 7 that detects a signal transmitted from the vehicle using small-area wireless communication; and a controller 22 that controls the power transmission devices. The power transmission devices are arranged side by side within a road in a travel direction of the vehicle. The one first detection device is placed so as to be able to detect a signal on an upstream side of the most upstream power transmission device in the travel direction of the vehicle. A control device controls power transmission from the power transmission devices other than a first power transmission device located most upstream in the travel direction of the vehicle, based on the signal detected by the first detection device and power transmission result information in power transmission devices located upstream of the relevant power transmission device.SELECTED DRAWING: Figure 5

    【課題】複数の送電装置を有する地上給電装置について、車両から送信された情報に基づいて各送電装置を制御する。【解決手段】車両3に非接触で電力を送電する地上給電装置2は、車両に電力を送電する複数の送電装置4と、車両から狭域無線通信を用いて発信された信号を検出する少なくとも一つの検出装置7と、送電装置を制御するコントローラ22と、を備える。送電装置は、車両の進行方向に並んで道路内に配置される。一つの第1検出装置は、車両の進行方向において、最上流の送電装置よりも上流側において信号を検出することができるように配置される。制御装置は、車両の進行方向において最上流に位置する第1送電装置以外の送電装置からの送電を、第1検出装置によって検出された信号と当該送電装置よりも上流側に位置する送電装置における送電結果情報と基づいて、制御する。【選択図】図5
