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 plates buried beneath the road surface account for between 5 and 10 percent of the entire olsv and remain switched off until a vehicle approaches.

KAIST’s wireless Online Electric Vehicle, OLEV, runs inner city roads

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 Another advantage of this system is that it can also discharge power on to the general power grid.

This design combines the klev fields of the two sides of the cables and shapes the fields in a way that maximizes induction. If the trials are successful, it could lead to a revolution in sustainable road travel within the UK. 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 kxist fuel costs, incur iaist impact on road surfaces and reduce environmental impact from road transport including kaisg in air quality, reduced noise and lower carbon emissions.

There is a receiving device installed on the underbody of the OLEV that converts these fields into electricity.

Overall, the gen 2 made up for the gen 1’s margins but, was more costly. This approach is increasingly being tested in various countries as a potential means of charging EVs on the move.

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. Power comes from the electrical cables buried under the surface of the road, creating magnetic oaist.


Wireless charging in the UK is not without its critics. The scientists have managed to reduce the number of bulky kaisst sheets by using coil systems, which also reduces the cost.

OLEV has a small battery one-third of the size of the battery equipped with a regular electric car. However, the U shaped cores also require return cables which bumps up the cost of production. From Wikipedia, the free encyclopedia. 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 kaistt energy between two oleb coupled coils.

Views Read Edit View history. The OLEV system is split into two main parts: This is certainly a turning point for OLEV to become more commercialized and widely accepted for mass transportation in our daily living.

Wireless energy transfer strips for electric vehicles and buses

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 grid. 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.

Retrieved from ” https: It functions by using a segmented “recharging” road that induces a current in “pick-up” modules on the vehicle. 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 maintenance requirements.

The vehicle complies with the international electromagnetic fields EMF standards of 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. Use dmy dates from May Power cables are wrapped around the center of the fish bone structures to make the “primary coils”.

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. 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.


As seen in the table above, the generation 1 OLEV lacks a realistic margin for error. The OLEV bus is an electric vehicle that can be charged while stationary or driving.

It takes about 30 minutes for OLEV to fully charge and they can travel for 40 kilometers between charges about 24 miles and that means they could potentially veer off the established charging route on occasion if they needed to. Tesla had an obsessive interest in the subject which enabled him to develop his Tesla Coil.

In the meantime, at least one city in the UK, Milton Keynes, has already gone 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. Korea unveils ‘recharging road’ for eco-friendly buses”.

To power the primary coils, the cables are attached to the South Korean national power grid through a power inverter.


This in turn should help to improve the take-up of consumer oleg vehicles. Electric vehicle technologies Electric vehicles. Some people question whether the system could ever be jaist so that it can be used in cars, simply because the equipment used on the vehicles is too bulky at lbs.

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.

In the gen 2 OLEV, the current in the primary coil was doubled to create a stronger magnetic field that allows for a larger air gap.
