Abstract : In present day with increase in pollution, fuel prices and depletion in resources, world is moving towards renewable energy. In this process Electric Vehicles (EV) play a major role. In the automobile industry EVs are the future because every country, industry is trying to decrease global warming and pollution by using technology which is sustainable. Electrical vehicle uses power from batteries to run. Batteries need to be charged to use electric vehicles. The charging system of EV can be either wired or wireless. Considering various advantages and disadvantages, Wireless Power Transfer (WPT) system is found to be one of the most efficient technique. In this work the design of wireless power transfer for electric vehicle to grid technology and the compensation network for the same is discussed. The inductive coils, transmitter and receiver are designed and simulated in ANSYS Maxwell platform. Different model of coils with and without magnetic shielding are compared. Quality factor of transmitter and receiver of every model is calculated and results are tabulated. The coil model with good power transfer efficiency is discussed. Choosing the best performed coil, efficiency comparison with varying distance between the coils is studied and results are tabulated.
