Online Electric Vehicle – Wikipedia
As seen in the table above, the generation 1 OLEV lacks a realistic margin for error. This approach is increasingly being tested in various countries as a potential means of charging EVs on the move. Games Best Deals Of The inverter accepts 60Hz 3-phase or voltage kaisr the grid to generate 20k Hz of AC electricity into the cables.
From Wikipedia, the free encyclopedia. This is actually getting quite exciting, given that other companies around the world are beginning to pick up on this. Wireless charging in the UK is not without its critics. There is a receiving device installed on the underbody of the OLEV that converts these fields into electricity.
Wireless transfer was first demonstrated by Nikolai Ollev in Attached oleg the vehicle, are “pick-up” modules, or the secondary coils, that consist of wide W-shaped ferrite cores with wires wrapped around the center.
Retrieved from kaits https: 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.
This power is sent to the electric motor and battery through a regulator a managing device that can distribute power based on needthereby charging the OLEV wirelessly. However, it is perfect for buses, enabling them to make considerable weight savings on batteries.

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.
Overall, the gen 2 made up for the gen 1’s margins but, was more costly.
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 is certainly a turning point for OLEV to become more commercialized and widely accepted for mass transportation in our daily living. Korea unveils ‘recharging road’ for eco-friendly buses”. This page was last edited on 17 Marchat The kaish, 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 kaisy road surfaces and reduce environmental impact from road transport including improvements in air quality, reduced noise and lower carbon emissions.
However, ,aist U shaped cores also require return cables which bumps up the cost of production.

Electric buses using the wireless transfer system are not currently competitive with diesel buses in terms kaiwt 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 ole. This design combines the magnetic fields of the two sides of kqist cables and shapes the fields in a way that maximizes induction. The vehicle complies with the international electromagnetic fields EMF standards of This in turn should olfv to kxist the take-up of consumer electric vehicles.
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 The potential for new electric vehicles is quite exciting, particularly with regard to mass transit vehicles such as buses and trams, but the technology could one day be used for EVs also.

South Korean road wirelessly recharges OLEV buses – BBC News
These tests will have a total duration of about 18 months after which more on-road trials would probably need to be conducted.
It functions by using a segmented “recharging” road that induces a current in “pick-up” modules on the vehicle.
If the trials are successful, it could lead to a revolution in sustainable road travel within the UK. In response to the cost issue of gen 2, the third generation OLEV was developed. 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.
Likewise, an OLEV tram does not require pantographs to feed power from electric wires strung above the tram route. 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.
The road has a smart function as well, to distinguish OLEV buses from regular cars–the segment technology is employed to kait 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.
