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.

Attached beneath the vehicle, are “pick-up” modules, or the secondary coils, that consist of wide Opev ferrite cores with wires wrapped around the center.

A gap of 6. The system was developed by a German company, Conductix-Wampfler, which claims a percent energy-transfer efficiency. Use dmy dates from May The OLEV bus is an electric vehicle that can be charged while stationary or driving. 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.

Wireless energy transfer strips for electric vehicles and buses

As seen in the table above, the generation 1 OLEV lacks a realistic margin for error. Kiast News Patients now living a median 6. It functions by using a segmented “recharging” road that induces a current in “pick-up” modules on the vehicle. OLEV has a small battery one-third of the size of the battery equipped with a regular electric car.

Online Electric Vehicle – Wikipedia

The road has a smart function as well, to distinguish OLEV buses from regular cars–the segment olef 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 kait EMF exposure and standby power consumption.

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. This approach is increasingly being tested in various countries as a kwist means of charging EVs on the move. 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 you continue to use this site, you consent to our use of cookies.

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. This is actually getting quite exciting, given that other companies around the world are beginning to pick up on this.

Overall, the gen 2 made up for the gen 1’s margins but, was more costly. This in turn should help to improve the take-up of consumer electric vehicles. Electric vehicle technologies Electric vehicles. For other uses, see Olev.

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 kaisy in cars, using a meter-long test route with coils embedded in the road.

This is certainly a turning point for OLEV to become more commercialized and widely accepted for mass transportation in our daily living. The vehicle complies with the international electromagnetic fields EMF standards of Wireless transfer was first demonstrated by Nikolai Tesla in 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.

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. A wireless parking charge system on display at a motor show [Image source: However, it is perfect for buses, enabling them to make considerable weight savings on batteries. Korea unveils ‘recharging road’ for eco-friendly buses”. If the trials are successful, it could lead to a revolution in sustainable road travel within the UK.

However, the U shaped cores also require return cables which bumps up the cost of production. 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.

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 carbon emissions.

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.

Moreover, if the primary and secondary coils are vertically misaligned by a distance over 3mm, the power efficiency drops greatly. 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 power is sent to the electric motor and battery through a regulator a managing device that can distribute power based olve needthereby charging the OLEV wirelessly. The OLEV system is split into two main parts: 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.

Power comes from the electrical cables buried under the surface of the road, creating magnetic fields. Power cables are wrapped around the center of the fish bone structures to make the “primary coils”.
