Abstract

In this study, electric vehicle charging gun and radio energy transmission technology are integrated to overcome the problem of unstable efficiency of electric vehicle wireless power transmission (WPT) due to misalignment of the coupling coil of the charging gun. It introduces a novel dual-coupled LCC compensation circuit structure combined with a spiral-inserted magnetic core coupling coil. Using simulations in ANSYS and MATLAB, the design demonstrates stable output efficiency with deviations below 0.4% for displacements up to 30mm. This work advances WPT systems by enhancing stability and efficiency, offering a practical solution for real-world applications in electric vehicle charging.
