Electric vehicle are gaining importance day by day because of the benefits it have over conventional vehicles. One of the major problems with EV is its battery charging process which can be simplified by using Wireless Power Transfer (WPT) System It removes the need of annoying cables and provides safety to user. This paper discuss about the technique and consideration to be made while designing a system to charge vehicle wirelessly.

All conventional vehicles are powered by an internal combustion engine (ICE) only. These conventional vehicle produce exhaust gases during operation which are harmful for human health.
But electric vehicles (EVs) run on electricity only. They are propelled by one or more electric motors which are powered by rechargeable battery packs. Due to this electric vehicles have several advantages over conventional vehicles. No harmful gas emission. Fuel cost will be up to 70% less than conventional vehicle, maintenance cost is less, ideal for stop-start city driving as no energy is utilise when the vehicle is stationary.[6][7]
Besides the high initial cost , the long charging time of EV batteries also makes the EV not acceptable to many drivers. For a single charge, it takes about one half-hour to several hours depending on the power level of the charger, which is many times longer than the gasoline refuelling process.
