A 120 kW wireless charging system for electric vehicles ( EV ) has been proposed by researchers at the Oak Ridge National Laboratory ( ORNL ) in Tennessee . “We are talking, and we do talk, with several OEMs,” said Galigekere. The system works by converting direct current ( DC ) to high frequency alternating current , generating a magnetic field . After the electricity is transferred to a second coil , it is converted back to DC and stored in the EV battery pack . ORNL researchers said eventually they want to create a wireless charging system that can deliver a 350 kW charge and be integrated into vehicles .
