Charging electrical vehicles with wireless power transmission

Since, the batteries provide the required power for propelling the EVs, they should be powerful, long-lasting enough, and rechargeable with the minimum of the time. Resonance Inductive Coupling is a technology that could introduce a convenient charging system to the EVs with fulfilling the aforementioned requirements for the batteries. The inherent characteristic of the antennas makes them suitable in Resonance Inductive Coupling technology. In this paper, we present a configuration, consists of two optimized square loop wire antennas in communication and tuned at mutual frequency with aim of showing the improvement of the size of the batteries and the power efficiency over longer distance. The presented configuration is simulated by Matlab in order to investigate its coupling performance and the effect of the longer distance on the coupling performance. And then, the results obtained by Mtlab are plotted and compared with the results obtained by FEKO-Lite for checking and verifying our results.
