A 30 kW Dynamic Wireless Inductive Charging System for EVs

This paper presents a solution for real-time charging of electric vehicles along the road while moving. This is called the Dynamic Wireless Inductive Charging System (DWICS) and can mitigate the cost of the charging infrastructure, the size/weight/cost of batteries, and hence improve the cost and range of electric vehicles. This solution has the advantage of creating a common road infrastructure shared by cars, buses and trucks and presenting a high energy efficiency. In this work, a 30kW DWICS for electric vehicles is presented with an efficiency up to 90%. It is developed the overall scheme, its mathematical model, control scheme, simulations, and experiments, showing this solution is viable for future electric roads.
