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. 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 functions by kkaist a segmented “recharging” road that induces a current in “pick-up” modules on the vehicle. It takes about 30 minutes for OLEV to fully charge and they can travel for 40 kilometers between charges kajst 24 miles and that means they could potentially veer off the established charging route on occasion if they needed to.

Breaking News Patients now living a median 6. This approach is increasingly being tested ilev various countries as a potential means of charging EVs on the move.

The scientists have managed to reduce the number of bulky ferrite sheets by using coil systems, which also reduces the cost. Views Read Edit View history.

This in turn should oelv to improve the take-up of consumer electric vehicles. In response to the cost issue of gen 2, the third generation OLEV was developed.

However, the U shaped cores also require return cables which bumps up the cost of production. 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 advantage of this system is that it can also discharge power on to the general power grid. Power cables are wrapped around the center of the fish bone structures to make the “primary coils”. 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. 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.

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. 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.

This device, which olfv 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 olfv coupled coils. 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 A wireless parking charge system on display at a motor show [Image source: The inverter accepts 60Hz 3-phase or voltage kist the grid to generate 20k Hz of AC electricity into the cables.

However, it is perfect for buses, enabling them to make considerable weight savings on batteries. This loev was last edited on 17 Marchat OLEV has a small battery one-third of the size of the battery equipped with a regular electric car.

Korea unveils ‘recharging road’ for eco-friendly buses”. Alongside innovative battery technology, another potential method for charging electric vehicles EVs could be wireless energy transfer strips installed on road surfaces. Wireless charging in the UK is not without its critics.

Wireless energy transfer strips for electric vehicles and buses

Likewise, an OLEV tram does not require pantographs to feed power from electric wires strung above the tram route. These tests will have a total duration of about 18 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.
