Views Read Edit View history. The test vehicle, a sports car converted into an electric vehicle, managed to travel the entire route at a moderate speed while simultaneously charging its battery.

For other uses, see Olev. In response to the cost issue of gen 2, the third generation OLEV was developed.

The scientists have managed to reduce the number of bulky ferrite sheets by using coil systems, which also reduces the cost. The plates buried beneath the road surface account for between 5 and 10 percent of the entire route and remain switched off until a vehicle approaches.

Attached beneath the vehicle, are “pick-up” modules, or the secondary coils, that consist of wide W-shaped ferrite cores with oleg wrapped around the center. Breaking News Patients now living a median 6. This design combines the magnetic fields of the two sides of the cables and shapes the fields in a way that maximizes induction.

Overall, the kaiet 3 OLEV made up for the gen 1’s small margins and gen 2’s increased cost. This means that excess energy from the grid could be fed into these cars, using them as energy storage facilities until the power is required when it could be returned to the kais.


This is accomplished by olef technological issues that limit the commercialization of electric vehicles such as price, oelv, volume, driving distance, and lack of charging infrastructure.

The potential for new electric vehicles is quite exciting, particularly with regard to mass transit vehicles such as buses and trams, but the technology could one day be used for EVs also.

Retrieved from ” https: The tests, due to take place off-road at some point either this year or next, will evaluate the potential of the system to help reduce fuel costs, incur minimum impact on road surfaces and reduce environmental impact from road transport including improvements in air quality, reduced noise and lower carbon emissions. KAIST, via Wired Magazine ] Alongside innovative battery technology, another potential method for charging electric vehicles EVs could be wireless energy transfer strips installed on road surfaces.


OLEV is a groundbreaking technology that accelerates the development of purely electric vehicles as a viable option for future transportation systems, be they personal vehicles or public transit. The inverter accepts 60Hz 3-phase or voltage from the grid oolev generate 20k Hz of AC electricity into the cables. To power the primary coils, the cables are attached to the South Korean national power grid through a power inverter.

This power is sent to the electric motor and battery through a regulator a managing device that kaidt distribute power based on needthereby charging the OLEV wirelessly.

Wireless charging in the UK is not without its critics.

Alongside innovative battery technology, another potential method for charging electric vehicles EVs could be wireless energy transfer strips installed on road surfaces. An expanding bubble in an extra dimension Uppsala University Rerouting nerves during amputation reduces phantom limb pain before it starts MediaSource Proportion of cancers associated with excess body weight varies considerably by state American Cancer Society Reducing drinking could help with smoking cessation, research finds Oregon State University View all latest news.


This in turn should help to improve the take-up of consumer electric vehicles.

Electric vehicle technologies Electric vehicles. By using this site, you agree to the Terms of Use and Privacy Policy. There is a receiving device installed on the underbody of the OLEV that converts these fields into electricity.

The OLEV system is split into two main parts: From Wikipedia, the free encyclopedia. The wireless transfer system means that batteries in electric vehicles can be reduced in size to about a third of that you would normally expect to find in an electric car.

Online Electric Vehicle

This is certainly a turning point for OLEV to become more opev and widely accepted for mass transportation in our daily living. OLEV has a small battery one-third of the size of the battery equipped with a regular electric car.

These tests will have a total duration loev about 18 months after which more on-road trials would probably need to be conducted.

Moreover, if the primary and secondary coils are vertically misaligned by a distance over 3mm, the power efficiency drops greatly. This page was last edited on 17 Marchat Use dmy dates from May This device, which produces high voltage, high frequency alternating currents, enabled Tesla to transfer power over short oolev without interconnecting wires via resonant inductive coupling, the near-field wireless transmission of electrical energy between two magnetically coupled coils.
