The On-Line Electric Vehicle (OLEV) is an electric vehicle that can be charged wirelessly while standing still (static charging) or in-motion (dynamic charging). OLEV receives power from the road wirelessly thanks to a new technology known as Shaped Magnetic Field In Resonance (SMFIR). Power Lines are buried 15 cm under the road surface. These electrical cables generate a magnetic field. There is a power Pick-up Module (coils sets) under the OLEV. The power transfer is only effective between two resonant coils – Road-Embedded primary Power Track coil and vehicle attached secondary Pick-up coil. OLEV’s battery is smaller comparing to the battery pack of the conventional EV. The distance gap between the road surface and the vehicle is 20 cm.
