A mid-distance wireless charging system for Electric Vehicles based on magnetic resonance coupled 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,and equations that obtain six coupled coefficient was deduced to describe the four-coil mutual-coupled WPT system.Then,simulation of mid-distance wireless charging system is established using SIMULINK software,and the experimental platform is set up to verify the wireless charging system that can transfer 3300 W power over 22cm distance efficiently.
