Multimode Contactless Vehicle Charging System

Abstract — Wireless power transfer system transfer electric energy from a source to load without any wired connection WPT’s are attractive for many industrial applications because of their advantages compared to the wired charging such as no use of any wires, easy charging and comfortable transmission of power in adverse environmental conditions. In WPT we used two coils and we charge our battery with the use of magnetic coupling between two coils. In electric vehicle charging method transmitter coils are placed under the road and receiver coils are placed in the vehicle. IWPT, method is mainly used for high power transfer applications like EV charging because its exhibits greater efficiency. As we know the battery is heart of e-vehicle, without battery E-vehicle there is no use of it. But according to the size of battery it has its own specific limitation. Aim of this project is to provide charging to battery in either in both modes moving and steady.
