High Efficiency Wireless Charging of Electric Vehicle Using High Temperature Superconducting Coils

Abstract

Wireless Power Transfer (WPT) technology is gaining significant attention for electric vehicle (EV) charging applications due to its enhanced safety, convenience, and elimination of physical connectors. However, conventional inductive charging systems using copper coils suffer from considerable conduction losses and reduced efficiency, particularly in high-power EV charging scenarios and under misalignment conditions. To address these limitations, this work presents the design and simulation of a high-efficiency inductive wireless power transfer system employing High-Temperature Superconducting (HTS) coils.The proposed system incorporates a Series–Series (SS) compensation network to achieve effective reactive power cancellation, improved power transfer capability, and stable operation over a wide range of coupling conditions. The design methodology focuses on optimizing coil geometry, operating frequency, and compensation parameters to enhance system performance and suitability for EV charging applications. A detailed simulation model of the proposed WPT system is developed using MATLAB/Simulink, enabling accurate analysis of voltage, current, power transfer, and efficiency characteristics under various operating conditions. In this work, superconducting coils are employed for wireless power transfer, enabling significantly lower resistive losses and higher efficiency when compared to conventional coil-based wireless charging technologies. The simulation results validate that the proposed design achieves superior efficiency and power transfer performance, demonstrating its potential for next-generation high-power EV wireless charging systems.
