The Korea Advanced Institute of Science and Technology (KAIST) has created an electric vehicle that can be charged while stationary or driving, thus removing the need to stop at a charging station.

The Online Electric Vehicle (OLEV) receives power wirelessly through the application of Shaped Magnetic Field in Resonance, a technology that enables electric vehicles to transfer electricity wirelessly from the road surface while moving.

Power comes from electric cables buried under the surface of the road, creating magnetic fields. A receiving device installed on the under-body of the OLEV converts these fields into electricity at an 85% maximum power transmission efficiency rate.

OLEV trams and shuttle busses have already entered operation at an amusement park in Seoul and on the KAIST campus, and the City of Gumi in South Korea is providing its citizens with OLEV-based public transportation services this week.
