Using polyphase electromagnetic coupling coils with rotating magnetic fields to boost the power, researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory have demonstrated breakthrough performance for wireless charging of electric vehicles. A recent series of prototype demonstrations have established the effectiveness of the technology, which ORNL is seeking to license to manufacturers. More research is focused on developing even higher power levels suitable for larger vehicles, getting the system to mass production-level readiness and exploring more applications. […]
