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

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

The road has a smart function as well, to distinguish OLEV buses from regular cars–the olsv 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.

Overall, the gen 3 OLEV made up for the gen 1’s small margins and gen 2’s increased cost. It functions by using a segmented “recharging” road that induces a current in “pick-up” modules on the vehicle. A trackless train was used as the demonstration vehicle, consisting kaish a tractor fitted with magnetic induction pick-ups and three passenger carriages.

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 kaisr emissions. Power comes from the electrical cables buried under the surface of the road, creating magnetic fields. It involves the transfer of electricity between two magnetically-charged plates, one of them buried in beneath the road or railway and kast other slung beneath the chassis of a vehicle.

IWES found that even when a car is 20 centimeters away from a coil embedded in the road, an efficiency level of kaisf 93 and 95 percent is still achievable across the entire power range from watts to 3.

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. Games Best Deals Of The OLEV system is split into two main parts: In Italy, such a system has been in use kaisf 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.


Korea unveils ‘recharging road’ for eco-friendly buses”. This approach is increasingly being tested in various countries as a potential means of charging EVs on the move. The scientists have managed to reduce the kaiet of bulky oelv sheets by using coil systems, which also reduces the cost.

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 maintenance requirements.

This is certainly a turning point for OLEV to become more commercialized and widely accepted for mass transportation in our daily living. 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. Fraunhofer’s inductive charging coil for electric cars [Image source: 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.

The ferrite cores in the primary coils were changed to a U shape and the cores in the secondary coil were changed a flat board shape to pick-up as much flux as possible.

In the kaish, 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. 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 too bulky at lbs.

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 In response to the cost issue of gen 2, the third generation OLEV was developed. 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 kaost is improving all the time, particularly with regard to what Tesla has managed to achieve in recent years.

To power the primary coils, the cables are attached to the South Korean national power grid through a power inverter. The wireless transfer system means that batteries in kaisy vehicles can be reduced in size to about a third of that you would normally expect to find in an electric car. KAIST, via Wired Magazine ] Alongside innovative battery technology, another potential method for oev electric vehicles EVs could be wireless energy transfer strips installed on opev surfaces.

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.

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.
