Electric vehicle (EVs) have been attracting a lot of attention as part of the proactive approach to global environment problems being taken around the world. However, existing EV batteries have not yet achieved high enough energy density of and thsu, EVs are not very common. The construction of the EV charging infrastructure is a key factor in solving this problem. Our objective is to construct charging system for a contactless power station for moving EVs, focusing on of safe handling of the high-power equipment and reducing the stop time required for charging. The electric power needed to operate this system is transmitted from the power transmission coil, which is located on the road, to receiving coil, which is installed on the underside of the EV. We designed and constructed a one-fifth of an actual vehicle scale model coil, and we used it to investigate the coupling factor and efficiency between coils when the gap between the power transmission coil and a receiving coil was changed.
