WIRELESS POWER TRANSFER BASED CHARGING STATION FOR ELECTRIC VEHICLE APPLICATION

The emerging wireless electric vehicle charging technology has attracted more and more attention in recent years. The electric vehicle charging system increases the load on the utility grid. This load is managed by charging at less rush hour which is not satisfactory for vehicle. Therefore, an auxiliary method of wireless charging has been developed to charge electric vehicles. In this paper an electric vehicle charging by wireless method has been developed. It involves the use of transmitter coils fixed in the road and under the electric vehicle for the purpose of fast charging using the principle of electromagnetic induction. Between the both transmitter and receiver the driving circuit is used and for the switching operation MOSFET is used. As the vehicle is present or absent according to that the transmitter coil circuit gets on and off. This paper shows the wireless charging system which is based on magnetic coupled resonant power transmission.
