Bidirectional Wireless Power Transfer System for Electric Vehicle

Abstract: The automobile industry in India is on the verge of shifting from the conventional petrol or diesel engines to electric vehicles. The conventional fuel used for automobile is limited and has several problems such as hazards to the environment due to combustion of fuel. The electric vehicle overcomes the problems associated to fuel combustion and provides the effective solution for transportation. The flexibility with electric vehicles has opened the doors of opportunities for the researchers to develop the sustainable solutions in automobile sector. The problems associated with EV are the battery charging time and the performance of the battery. The bidirectional transfer of the power enables the grid connection of electric vehicles. As the power transfer is in both directions charging and discharging of the batteries is possible with fulfillment of controlled output requirements. The wireless transfer of power is introduced long back but is not implemented at large scale as the efficiency of the system is not so high. The implemented module for bidirectional wireless power transfer is presented in this paper.
