Dynamic Wireless Charging in EV

Abstract

The increasing adoption of electric vehicles (EVs) presents both an opportunity and a challenge for sustainable transportation, with limited charging infrastructure and long charging times being major barriers. This research explores the concept of dynamic wireless charging (DWC) for EVs, a technology that enables vehicles to be charged while moving on roads equipped with embedded wireless power transfer (WPT) systems. Through the use of resonant inductive coupling or capacitive power transfer, charging coils embedded beneath the road surface transfer energy to receiver coils installed in EVs, allowing continuous or intermittent energy supply during motion. This paper investigates the technical principles and infrastructure requirements of dynamic charging systems, including energy transfer efficiency, vehicle alignment, and real-time battery management. Furthermore, it examines the potential of integrating renewable energy sources, such as solar-powered roads, into this system to enhance sustainability. The study discusses the environmental and economic impact of implementing wireless charging highways, along with the future vision of smart cities where electric vehicles continuously charge while on the move. This technology could play a crucial role in accelerating the global transition to electric mobility, offering a scalable solution to the limitations of current EV charging infrastructure.
