Wireless electric road system for propulsion and charging of electric vehicles in highways

Wireless charging is a technology that is projected to promote the acceptance of Electric Vehicles (EV) due to its capability to reduce transport emissions, improve charging convenience and promote environmental sustainability. Technological advancement in dynamic wireless power transfer has contributed to the expansion of Electric Road Systems (ERS) that offer charging infrastructure for Electric Vehicles (EV). ERS is an emerging technology aimed at electrifying road transport by supplying EV with power enabling EV's with the possibility to charge while driving. ERS is an important technology to enhance the electrification of EV thereby addressing battery limitations and further decrease fossil fuel dependency. Although prior studies have evaluation the potential of ERS. There are fewer studies that extensively explored the applicability of wireless ERS in highways or long-distance corridors. Therefore, this article identifies factors as challenges that influences the deployment of wireless ERS and potential application of wireless ERS for sustainable transportation. More importantly this study investigates the feasibility of wireless ERS to decarbonize road vehicles in long-distance corridors. Key findings from this article assess the maturity level of different ERS technologies by presenting use cases and initiatives of ERS focusing on wireless power transfer subsystem and the development of ERS in highways.
