Abstract

The availability of a convenient charging mechanism will help greatly in dispersal of Electric Vehicles more widely. The concept of Wireless transfer of electrical energy will make this possible. The feasibility of wireless power transfer for Electric Vehicles by electromagnetic resonance coupling is investigated in this paper. The experiment is carried out on small sized antennas that can be equipped at the bottom of a vehicle. The efficiency characteristics of power transmitted wirelessly are analyzed by varying frequency of power, gap between receiving and transmitting coils and power to be transmitted. The feasibility of wireless power transfer with large air gaps and high efficiency by small sized antennas is proposed and analyzed in this paper.
