Another system is currently under development at Utah State University, supported by funding from the Federal Transit Administration and an induction system also launched in The Netherlands in This in turn should help to improve the take-up of consumer electric vehicles. For example, Dr Paul Nieuwenhuis the director of Cardiff Business School’s Electric Vehicle Centre of Excellence is fairly skeptical, on grounds of the cost and the fact that battery technology is improving all the time, particularly with regard to what Tesla has managed to achieve in recent years.

The scientists have managed to reduce the number of bulky ferrite sheets by using coil systems, which also reduces the cost. The OLEV bus is an electric vehicle that can be charged while stationary or driving.

South Korean road wirelessly recharges OLEV buses – BBC News

It functions by using a segmented “recharging” road that induces a current in “pick-up” modules on the vehicle. 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.

This is actually getting quite exciting, given that other companies around the world are beginning to pick up on this. After the successful operation of the two OLEV buses by the end of this year, Gumi City plans to provide ten more such buses by Retrieved from ” https: Breaking News Patients now living a median 6.

Games Best Deals Of To power the primary coils, the cables are attached to the South Korean national power grid through a power inverter. The secondary coil uses a thicker variation of the w-shaped cores as a way to make up for the lesser area kaizt the magnetic flux to flow through compared to gen 2.

South Korean road wirelessly recharges OLEV buses

The lower current means a smaller magnetic field and requires the secondary coil to be very close to the floor, which can be an issue while driving. A wireless parking charge system on display at a motor show [Image source: IWES found that even when a car is 20 centimeters away from a coil embedded in the road, an efficiency level of between 93 and 95 percent is still achievable across the entire power range from watts to 3.


Moreover, if the primary and secondary coils are vertically misaligned by a distance over 3mm, the power kaiat drops greatly.

Some people question whether the system could ever be refined so that it can be used in cars, simply because the equipment used on the vehicles is kaits bulky at lbs. Overall, the gen 2 made up for the gen 1’s margins but, was more costly. Another advantage of this system is that it can also discharge power on to the general power grid.

A gap of 6. Electric vehicle technologies Electric vehicles.

Electric buses using the wireless transfer system are not currently competitive with diesel buses in terms of capital costs but they are in terms of total ownership costs because of the savings on batteries that are possible with this system as well as the low kajst requirements.

It involves the transfer of electricity between two magnetically-charged plates, one of them buried in beneath the road or railway and the other slung beneath the chassis of a vehicle. This power is sent to the electric motor and battery through a regulator a managing device that can distribute power based on needthereby charging the OLEV wirelessly.

OLEV is kaistt 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.

Online Electric Vehicle – Wikipedia

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. Power cables are wrapped around the center of the fish bone structures to make the “primary coils”.

The Online Electric Vehicle OLEV is an electric vehicle that charges wirelessly while moving using electromagnetic induction the wireless transfer of power through magnetic fields. In response to the cost issue of gen 2, the third generation OLEV was developed.

In Italy, such a system has been in use in Genoa and Turin for over ten years, providing 10 to 15 percent of the power for 30 electric buses which recharge at each bus stop.

The OLEV system is split into two main parts: This approach is increasingly being tested in various countries as a potential means of charging EVs on the move. This is certainly a turning point for OLEV to become more commercialized and widely accepted for mass transportation in our daily living.


In the meantime, at least one city in the UK, Milton Keynes, has already ollev ahead with its own wireless transfer system, though this is fairly limited and requires buses to stop for several minutes at a time while charging.

This is accomplished by solving technological issues that limit the commercialization of electric vehicles such as price, weight, volume, driving distance, and lack of charging infrastructure. The vehicle complies with the international electromagnetic fields EMF standards of 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.

The road has a smart function as well, to distinguish OLEV buses from regular cars–the segment technology is employed to control the power supply by switching on the power strip when OLEV buses pass along, but switching it off for other vehicles, thereby preventing EMF exposure and standby power consumption. This page was last edited on 17 Marchat Power comes from the electrical cables buried under the surface of the road, creating magnetic fields.

Alongside innovative battery technology, another potential method for charging electric vehicles EVs could be wireless energy transfer strips installed on road surfaces. Overall, the gen 3 OLEV made up for the gen 1’s small margins and gen 2’s increased cost. As seen in the table above, the generation 1 OLEV lacks a realistic margin for error.

This device, which produces high voltage, high frequency alternating currents, enabled Tesla to transfer power over short distances without interconnecting wires via resonant inductive coupling, the near-field wireless transmission of electrical energy between two magnetically coupled coils.

Two other Fraunhofer institutes, the Fraunhofer Institutes for Manufacturing Technology and Advanced Materials IFAM and for Transportation and Infrastructure Systems IVI, have successfully tested wireless transfer systems for use in cars, using a meter-long test route with coils embedded in the road.

However, it is perfect for buses, enabling them to make considerable weight savings on batteries. Skip to main content? There is a receiving device installed on the underbody of the OLEV that converts these fields into electricity.
