Design and Implementation of Wireless Power Transfer Systems for Electric Vehicle Charging

Abstract

Wireless Power Transfer (WPT) technology offers an innovative solution to the challenges associated with electric vehicle (EV) charging. This paper presents the design and implementation of a wireless power transfer system specifically for EV charging, focusing on the optimization of power transmission efficiency, safety, and system integration. The system leverages inductive coupling to transmit power from a primary coil to a secondary coil installed in the vehicle. Key design considerations, such as coil design, resonant frequency matching, power control, and electromagnetic interference mitigation, are explored. A prototype system is developed and tested for practical use in dynamic charging environments, such as in-motion charging, as well as stationary applications. Experimental results demonstrate the effectiveness of the WPT system in providing efficient, reliable, and scalable charging solutions for electric vehicles, with the potential to revolutionize the charging infrastructure for EVs.
