A 350 kW wireless charging system for electric vehicles ( EV ) has been demonstrated by researchers at EV (ORNL) in Brooklyn . The system works by converting direct current (DC) to high frequency alternating current, generating a magnetic field. “We went significantly up in power, but the footprint remained the same and the power electronics size actually shrunk,” project lead Veda Galigekere told Greentech Media in an interview. 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 120 kW charge and be embedded into roads.
