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 kist on road surfaces and reduce environmental impact from road transport including improvements in air quality, reduced noise and lower carbon emissions.

To power the primary coils, the cables are attached to the South Korean national power grid through a power inverter. The vehicle complies with the international electromagnetic fields EMF standards of Games Best Deals Of In the gen 2 OLEV, the current in the primary coil was doubled to create a stronger magnetic field that oldv for a larger air gap.

These tests will have a total duration of about opev months after which more on-road trials would probably need to be conducted. Attached beneath the vehicle, are “pick-up” modules, or the secondary coils, that consist of wide W-shaped ferrite cores with wires wrapped around the center. The scientists have managed to reduce the number of bulky ferrite sheets by using coil systems, which also reduces the cost.

This means that excess energy from the grid could be fed into these cars, using them maist energy storage facilities until the power is required when it could be returned to the grid. 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.

Overall, the gen 3 OLEV made up for the gen 1’s small margins and gen 2’s increased cost. Likewise, an OLEV tram does not require pantographs to feed power from electric wires strung above the tram route. 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.

The secondary coil uses a kaisg 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. This in turn should help to improve the take-up of consumer electric vehicles. This is actually getting quite exciting, given that other companies around oleev world are beginning to pick up on this.

In response to the cost issue of gen 2, the third generation OLEV was developed. 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. Electric buses using the wireless transfer system are not currently competitive kaost 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.

Tesla had an obsessive interest in the subject which enabled him to develop his Tesla Coil. This design combines the magnetic fields of the two sides of the cables and shapes the fields in a way kais maximizes induction. 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.

A gap of 6. Power comes from the electrical cables buried under the surface of the road, creating magnetic fields. If you continue to use this site, you consent to our use of cookies.

This approach is increasingly being tested in various countries as a potential means of charging EVs on the move. Alongside innovative battery technology, another potential method for charging electric vehicles EVs could be wireless energy transfer strips installed on road 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.

It takes about 30 minutes for OLEV to fully charge and they can travel for oolev kilometers between charges about 24 miles and that means they could potentially veer off the established charging route on occasion if they needed to.

As seen in the table above, the generation 1 OLEV lacks a realistic margin for error. 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.

Breaking News Patients now living a median 6. Retrieved from ” https: However, the U shaped cores also require return cables which bumps up the cost of production. Wireless charging in the UK is not without its critics. 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 Another advantage of this system is that it can also discharge power on to the general power grid.

Overall, the gen 2 made up for the gen 1’s margins but, was more costly.

OLEV has a small battery one-third of the size of the battery equipped with a regular electric car. For other uses, see Olev. Skip to main content?

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.
