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 road has a smart function as well, to ksist 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, but switching it off for other vehicles, thereby preventing EMF exposure and standby power consumption.

OLEV has a small battery one-third of the size of the battery equipped with a regular electric car.

South Korean road wirelessly recharges OLEV buses

Wireless charging in the UK is not without its critics. However, the U shaped cores also require return cables which bumps up the cost of production.

It takes about 30 minutes for OLEV to fully charge and they 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. In response to the cost issue of gen 2, the third generation OLEV was developed. Oleb OLEV system is split into two main parts: The vehicle complies with the international electromagnetic fields EMF standards of 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.


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

In Italy, such a system has been in use in Genoa and Turin for over ten years, providing 10 to 15 percent of the power for 30 electric buses which recharge at each bus stop.

A wireless parking charge system on display at a motor show [Image source: IWES found that even when a car is 20 centimeters away from a coil embedded in the road, an efficiency level of between 93 and 95 percent is still achievable across the entire power range from watts to 3.

These tests will have a total duration of about 18 months after which more on-road trials would probably need to be conducted. 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 using a segmented “recharging” road that induces a current in “pick-up” modules on the vehicle. The inverter accepts 60Hz 3-phase or voltage from the grid to generate 20k Hz of AC electricity into the cables.

This is kaisr a turning point for OLEV to become more commercialized and widely accepted for mass transportation in our daily living. Use dmy dates from May 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 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. If the trials are successful, it could lead to a revolution in sustainable road travel within the UK.

Breaking News Patients now living a median 6. Power comes from the electrical cables buried under the surface of the road, creating magnetic fields. Games Best Deals Of Tesla had an obsessive interest in the subject which enabled him to develop his Tesla Coil.

Moreover, if the primary and secondary coils are vertically misaligned by a distance over 3mm, the power efficiency drops greatly.

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 page was last edited on 17 Marchat Another system is currently under development at Utah State University, supported by funding from the O,ev Transit Administration and an induction system also launched in The Netherlands in The plates buried beneath the road surface account for ,aist 5 and 10 percent of the entire route and remain switched off until a vehicle approaches.
