INDUCTIVE POWER ROADWAYS

Abstract: VIDEO https://www.youtube.com/watch?v=AC6SDElu3Fo The cruising range of an electric vehicle (EV) can be greatly extended by a dynamic wireless charging system because the battery can be charged while the vehicle is moving. However, the investment in infrastructure can be enormous and has to be reduced to implement the system. This paper presents the design of a wireless power transfer system with road embedded transmitter coils to facilitate dynamic charging of EVs. A transmitter coil, which is relatively long compared with the circular receiver coil, has been designed to reduce the cost of the transmitter circuit. A prototype transmitter coil has been embedded into a road for evaluation of its characteristics.

We had designed a high-efficiency charging system that uses magnetic fields to wirelessly transmit large electric currents between metal. The long-term goal of the research is to develop an all-electric highway that wirelessly charges cars and trucks as they cruise down the road. The new technology has the potential to dramatically increase the driving range of electric vehicles and eventually transform highway travel, according to the researchers. "Our vision is that you'll be able to drive onto any highway and charge your car,"."Large-scale deployment would involve revamping the entire highway system and could even have applications beyond transportation."
