Abstract A mid-range wireless charging system for Electric Vehicles based on magnetic resonance coupled(MRC) wireless power transfer(WPT) technology is designed to improve convenience and safety compared with plug-in charger. Principle of WPT technology is explained using coupled- mode theory and equivalent circuit theory. Then, equations that include six coupling coefficients were deduced to describe the four-coil mutual-coupled WPT system. After that, simulation model of mid-range wireless charging system is established using Simulink, and the experimental platform is set up to verify the wireless charging system that can transfer 3?300W power over 22cm distance efficiently.
