Dynamic Wireless Charging of Electric Vehicles

Electric car sales have surged sixfold in the last five years, totalling more than 40 million. These vehicles are environmentally beneficial, have minimal operating and maintenance costs, and account for almost 11% of worldwide greenhouse gas emissions. They could be a critical technology in combating climate change and global pollution. Switching from traditional petrol or gas cars to electric vehicles (EVs) presents major hurdles in decreasing emissions, reducing operational expenses, and enhancing energy storage capabilities. Wireless charging electric vehicles provide hopeful answers to the drawbacks of wired charging like limited range and long charging times. This article outlines a thorough strategy to tackle the obstacles of wireless power transfer (WPT) for electric vehicles (EVs) through optimizing coupling frequency and coil design to improve efficiency, while reducing electromagnetic interference (EMI) and heat production. A new coil design and adaptive hardware are suggested to enhance power transfer efficiency (PTE) by determining the best magnetic resonant coupling WPT and reducing coil misalignment, a major obstacle to the widespread use of WPT for EVs. An innovative approach to creating and organizing lanes and amenities along roadsides for dynamic wireless charging (DWC) of electric vehicles (EVs) is presented. This involves enhancing transmitter coils (TCs), receiver coils (RCs), and compensation circuits. Dynamic Wireless Charging utilizes Resonant Inductive Coupling to transfer electrical power wirelessly between two coils. An alternating current in the primary coil creates a magnetic field, inducing a voltage in the secondary coil. This system is used for dynamic charging of Electric Vehicles, with primary coils installed beneath the road and secondary coils mounted on the EV. Efficiency is dependent on high-frequency AC and compensation network tuning. The manuscript introduced a novel method for dynamically charging electric vehicles demonstrating its potential for sustainable and cost-effective EV infrastructure. Future research will focus on enhancing system efficiency and extending the charging lane distance. DOI: https://doi.org/10.52783/pst.1502
