Transmission of electricity through the air

Korean scientists announced the successful testing of the new technology of wireless transmission of electricity on the railway. Technology- OLEV could revolutionize electric transporte.

OLEV (On-line Electric Vehicle), the result of joint development of leading Korean Institute of Science and Technology (KAIST) and the Korean Railway Research Institute (KRRI) - an example of a "pure" electric vehicles, does not need a provodov.

Using a unique non-contact magnetic system, the new product is powered by the energy bands, hidden beneath the surface of the road. Transportation can be recharged on the go, allowing you to avoid additional stops and the equipment room for zaryadki.

Route OLEV divided into segments, and only some of them are equipped with charging strips beneath the surface. Special equipment installed in the lower part of the vehicle collects electricity from the road and uses it to power the motor, or to charge the batteries that are included in areas without a magnetic coating. This mechanism provides electromagnetic safety of pedestrians and car owners who have to cross the "path» OLEV.

The journey from concept to commercial release OLEV took three years. An early prototype was working at a frequency of 20 kHz, and cope with the load of 100 kW - this was enough to power a city bus or tram. Step improvements include the tasks to improve efficiency, increase power transmission distance up to 20 cm and bringing the parameters in accordance with local normativami.

Tests carried out at the station Osong. According to scientists, the wireless power supply characterized by a stable capacity of 180 kW and a frequency of 60 kHz. Currently, scientists were able to prove that the technology can be applied not only on the railway. According to experts KRRI and KAIST in May there will be new trams and high-speed trains in September.
