Advancements in Efficient and Sustainable Wireless Charging for Electric Vehicles

The transition to Electric Vehicles (EVs) is crucial for sustainable transportation. However, the adoption of traditional plug-in charging systems remains limited due to their time-consuming nature and infrastructure demands. This study presents a Wireless Power Transfer (WPT) system leveraging inductive coupling to enhance EV charging efficiency, compatibility, and safety. The system converts AC to DC with power factor correction, then transforms it into high-frequency AC to energize the transmitter coil. The receiver coil generates alternating current (AC), which then converts to direct current (DC) for charging the battery. The proposed WPT model, developed using MATLAB Simulink Optimizer, demonstrates a charging efficiency ranging from 90 % to 93 %, resulting in energy losses as low as 10 % to 15 % and improved user convenience by reducing the need for manual plug-in operations. The developed model assumes a standard 60 kWh EV battery can be charged from 20 % to 80 % in approximately 3 hours using the proposed WPT system, compared to 5–6 hours with conventional plug-in chargers.
