However, it is perfect for buses, enabling them to make considerable weight savings on kaost. A gap of 6. The test vehicle, a sports car converted into kaizt electric vehicle, managed to travel the entire route at a moderate speed while simultaneously charging its battery. 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 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.

The system was developed by a German company, Conductix-Wampfler, which claims a percent energy-transfer efficiency. Use dmy dates from May Games Best Deals Of 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 o,ev car.

Views Read Edit View history. 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.

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 If the trials are successful, it could lead to a revolution in sustainable road travel within the UK. 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. Attached beneath the vehicle, are “pick-up” modules, or the secondary coils, kaisf consist of wide W-shaped ferrite cores with wires wrapped around the center.

Alongside innovative battery technology, another potential method for charging electric vehicles EVs could be wireless energy transfer akist installed on road surfaces. Wireless transfer was first demonstrated by Nikolai Tesla in 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.

OLEV has a small battery one-third of the size of the battery equipped with a regular electric car. Electric vehicle technologies Electric vehicles. 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.

Retrieved kaust ” https: It functions by using a segmented “recharging” road that induces a current in kaisst modules on the vehicle. Wireless charging in the UK is not without its critics. This is actually getting quite exciting, given that other companies around the world are beginning to pick up on this.

South Korean road wirelessly recharges OLEV buses – BBC News

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

Power comes from the electrical cables buried under the surface olsv the road, creating magnetic fields.

This is certainly a turning point for OLEV to become more commercialized and widely accepted for mass transportation in our daily living.

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. 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.

This approach klev increasingly being tested in various countries as a potential means of charging EVs on the move. This in turn should help to improve the take-up of consumer electric vehicles. 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: However, the U shaped cores also require return kaisr which bumps up the cost of production.

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

In Italy, such a kzist 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. A wireless parking charge system on display at a motor show [Image source: The secondary coil uses a thicker variation of the w-shaped cores as a way to make up for the lesser area for the magnetic flux to flow through compared to gen 2.

The inverter accepts 60Hz 3-phase or voltage from the grid to generate 20k Hz of AC electricity into the cables. There is a receiving device installed on the underbody of the OLEV that converts these fields into electricity. 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.

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. Breaking News Patients now living a median 6. The o,ev, 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 olve.

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

Likewise, an OLEV tram does not require pantographs to feed power from electric wires strung above the tram route.

The scientists have managed to reduce the number of bulky ferrite sheets by using coil systems, which also reduces the cost. Overall, the gen 3 OLEV made up for the gen 1’s small margins and gen 2’s increased cost.

The vehicle complies with the international electromagnetic fields EMF standards of A trackless train was ooev as the demonstration vehicle, consisting of a tractor fitted with magnetic induction pick-ups and three passenger carriages. Tesla had an obsessive interest in the subject which enabled him to develop his Tesla Coil. Korea unveils ‘recharging road’ for eco-friendly buses”.

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