One way to extend the range of electric vehicles may be to provide power wirelessly through coils placed under the surface of a road. But charging moving vehicles with high-power wireless chargers below them is complex.
Researchers at North Carolina State University have developed a method to deliver power to moving vehicles using simple electronic components, rather than the expensive power electronics or complex sensors previously employed. The system uses a specialized receiver that induces a burst of power only when a vehicle passes over a wireless transmitter. Initial models indicate that placing charging coils in 10 percent of a roadway would extend the driving range of an EV from about 60 miles to 300 miles, says Srdjan Lukic, an assistant professor of electrical engineering at NCSU.
