Online Electric Vehicle

Online Electric Vehicle (OLEV) is an electric vehicle using electromagnetic induction. On Tuesday, 9 March 2010 researchers from The Korea Advanced Institute of Science and Technology (KAIST) launched a public transport system[1] using a "recharging road". Electric power strips have been buried 30 cm (11.8 in) under the road surface and connected to the national grid. Pick-up equipment underneath the vehicle then collects power through non-contact magnetic induction which is used either to power the vehicle prime-mover or for battery charging. The demonstration system is a trackless train with an electric tractor hauling three passenger cars.

Gumi will have the world's first wireless electric bus in operation from July 2013 developed by KAIST. Electricity is wirelessly fed into the bus from the tracks.[2][3]

Earlier systems

The Korean system has developed technology that was pioneered in California in the 1990s, and claims to have overcome several problems including shielding users from the potentially harmful effects of electro-magnetic radiation.

A similar system, for tramcars, was patented in 1894 by Nikola Tesla, US Patent 514972.[4] but it was not developed at the time.


The state-funded institute announced it has applied for more than 120 patents[5] in connection with OLEV.


In November 2010, KAIST's Road-Embedded Rechargers was selected as Time's The 50 Best Inventions of 2010.[6][7]
