Research and Design of Wireless Charging System of Electric Vehicles

Abstract

The electric charging technology of electric vehicles has obtained increasingly extensive concerns by virtue of its potential powerful advantages. This paper respectively designs the software and hardware of the wireless charging system of electric vehicles, and then sets up the physical circuit and prototype to verify by the wireless charging experiment in the case of alignment and deviation of 15cm on the primary and secondary siding panel. The results show that the transmission power factor of the wireless system in the case of alignment and deviation is greater than 0.997, the highest efficiency from the power grid to the load is as high as 90%, and the wireless charging system operates stably.
