battery charging

Professor Yujing Liu shows the 500 kW inductive charging system which can be suitable for charging of electric ferries, trucks, and buses. DC (direct current) to DC efficiency can reach 98 percent. It transfers 500 kW per 2 square meters with 15 cm air gap between the ground pad and the onboard pad.
