Evaluation of Dynamic Wireless Power Transfer with Asphalt Road Embedded Transmitter Coils

Dynamic wireless power transfer has been proposed to solve the issue of performance problem of electric vehicles, which is a short cruising range. There is the eddy current loss in the conductors, which is in the magnetic field by the wireless power transfer system. This research reveals the influence on the efficiency of wireless power transfer by road structures with the road embedded transmitter coils. The reinforced concrete reduces 4.5% of coil efficiency. The aluminum shield plate of the transmitter coil can improve coil efficiency with reinforced concrete. However, it reduces coil efficiency on the soil pavement. Road embedment also reduces coil efficiency.
