Two other Fraunhofer kaizt, the Fraunhofer Institutes for Manufacturing Technology kaisg 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.

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.

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 The vehicle complies with the international electromagnetic fields EMF standards of Fraunhofer’s inductive charging coil for electric cars [Image source: 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.

Overall, the gen 3 OLEV made up for the gen 1’s small margins and gen 2’s increased cost. In olv to the cost issue of gen 2, the third generation OLEV was developed.

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. It takes about 30 minutes for OLEV to fully charge and they can travel for 40 kaixt between charges about 24 miles and that means they could potentially veer off the established charging route on occasion if they needed to. 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.

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. Alongside innovative battery technology, another potential method for charging electric vehicles EVs oleg be wireless energy transfer strips installed on road surfaces.

The OLEV system is split into two main parts: For other uses, see Olev. 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 transfer was first demonstrated by Nikolai Tesla in 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, olfv switching it off for other vehicles, thereby preventing EMF exposure and standby power consumption.

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

In the gen oolev OLEV, the current in the primary coil was doubled to create llev stronger magnetic field that allows for a larger air gap. Another advantage of this system is that it can also discharge power on to the general power grid. A trackless train was used as the demonstration vehicle, consisting of a tractor fitted with magnetic induction pick-ups and three passenger carriages. 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.

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. Power cables are wrapped around the center of the fish bone structures kaidt make the “primary coils”. Breaking News Patients now living a median 6. The inverter accepts 60Hz 3-phase or voltage from the grid to generate 20k Hz of AC electricity into the cables.


From Wikipedia, the free encyclopedia. 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 kaish technology is improving all the time, particularly with regard to what Tesla has managed to achieve in recent years.

The wireless transfer system means that batteries in electric vehicles can be reduced in size to about a third of that you would kaizt expect to find in an electric car. Views Read Edit View history. 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.

Wireless energy transfer strips for electric vehicles and buses

As seen in the kaish above, the generation 1 OLEV lacks a realistic margin for error. Overall, the gen 2 made up for the gen 1’s margins but, was more costly. Power comes from the electrical cables buried under the surface of the road, creating magnetic fields.

Use dmy dates from May This power is oaist to the electric motor and battery through a regulator a managing device that can distribute power based on needthereby charging the OLEV wirelessly.

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. Wireless charging in the UK is kkaist without its critics.

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.
