Wireless Charging System Design and Optimization for New Energy Vehicles

With the development of new energy vehicles, wireless charging technology has gradually become an important way of charging new energy vehicles. The traditional wired charging method has problems such as low charging efficiency and inconvenience, while wireless charging technology can realize wireless charging for new energy vehicles without plugging and unplugging the charger. Based on the wireless charging technology for new energy vehicles, this paper researches and designs an efficient and stable wireless charging system. After the construction of the system is completed, the performance of the wireless charging system is evaluated through simulation and testing, and the results show that the charging system can achieve a transmission efficiency of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mathbf{8 3. 9 \%}$</tex> under the 100 mm charging distance. The research results have certain theoretical and practical significance for promoting the development of new energy vehicle technology and the popularization of environmentally friendly transportation modes.
