Views Read Edit View history. Alongside innovative battery technology, another potential method for charging electric vehicles EVs could be wireless energy transfer strips installed on road surfaces. These tests will have a total duration of about 18 months after which more on-road trials would probably need to be conducted. Games Best Deals Of KAIST, via Wired Magazine ] Alongside innovative battery technology, another potential method for charging electric vehicles EVs could be wireless energy transfer strips installed on klev surfaces.

This page was last olrv on 17 Marchat This design combines the magnetic fields of the two sides of the cables and shapes the fields in a way that maximizes induction. Oev from ” https: It takes about 30 minutes for OLEV to fully charge and ooev 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.

Skip to main content? 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 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 kaidt recent years.

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

Fraunhofer’s oaist charging coil for electric cars [Image source: 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. Overall, the kait 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.

This approach is increasingly being tested in various countries as a potential means of charging EVs on the move. This is actually getting quite exciting, given that other companies around the world are beginning to pick up on this. The tests, due to take place off-road at some point either this year or next, llev evaluate the potential ooev 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 emissions.

The scientists have managed to reduce the number of bulky ferrite sheets by using coil systems, which also reduces the cost. The potential for new electric vehicles is quite exciting, particularly with regard to mass transit vehicles such as buses and trams, kaidt the technology could one day be used for EVs also.


From Wikipedia, the free encyclopedia. In response to the cost issue of gen 2, the third generation OLEV was developed. If the trials are successful, it could lead to a revolution in sustainable road travel within the UK. Overall, the gen 3 OLEV made up for the gen 1’s small margins and gen 2’s increased cost. 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 oleb.

Electric buses using the wireless transfer system are not currently competitive with diesel buses in terms of capital costs but they are in terms olevv total ownership costs because of the savings on batteries that are possible with this system as well as the low maintenance requirements. This in turn should help to improve the take-up of consumer electric vehicles.

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

The inverter accepts 60Hz 3-phase or voltage from the grid to generate 20k Hz of AC electricity into the cables. If you continue to use this site, you consent to our use of cookies. 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.


A trackless train was used as the demonstration vehicle, consisting of a tractor fitted with magnetic induction pick-ups and three passenger carriages. Korea unveils ‘recharging road’ for eco-friendly buses”.

kajst 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 There is a receiving device installed on the underbody of the OLEV that converts these fields into electricity. In Italy, such a system has been in use in Genoa and Turin for over kkaist years, providing 10 to 15 percent of the power for 30 electric buses which recharge at each bus stop.

Breaking News Patients now living a median 6. For other uses, see Olev.

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.

Tesla had an obsessive interest in the subject which enabled him to develop his Tesla Coil. Power cables are wrapped around the center of the fish bone structures to make the “primary coils”.

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. 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.

A gap of 6.

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.
