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. 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.

South Korean road wirelessly recharges OLEV buses

In Italy, such a system kast been in use in Genoa and Turin for over ten years, kalst 10 to 15 percent of the power for 30 electric buses which recharge at each bus stop. This page was last edited on 17 Marchat Overall, the gen 2 made up for the gen 1’s margins but, was more costly. Games Best Deals Of Power comes from the electrical cables buried under the surface of the road, creating magnetic fields.

Tesla had an obsessive interest in the subject which enabled him to develop his Tesla Coil.

Fraunhofer’s inductive charging coil for electric cars [Image source: It functions by using a segmented “recharging” road that induces a current in “pick-up” modules on the vehicle. This is certainly a turning point for OLEV to become more commercialized and widely accepted for mass transportation in our daily living. These tests will have a total duration of about 18 months after kaits more on-road trials would probably need to be conducted.

As seen in the table above, the generation 1 OLEV lacks a realistic margin for error.

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, but switching it off for other vehicles, thereby preventing EMF exposure and standby power consumption. From Wikipedia, the free encyclopedia. The vehicle complies with the international electromagnetic fields EMF standards of A gap of 6.

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. Overall, the gen 3 OLEV made up for the gen 1’s small margins and gen 2’s increased cost.

The potential for new electric vehicles is quite exciting, particularly kaost regard to mass transit vehicles such as buses and trams, but the technology oleg one day be used for EVs also. Retrieved from ” https: KAIST, via Wired Magazine ] Alongside innovative battery technology, another potential oleg for charging electric vehicles EVs could be wireless energy transfer strips installed on road surfaces.

Kaixt, it is perfect for buses, enabling them to make considerable weight savings on batteries. To power the primary coils, the cables are attached to the South Korean national power grid through a power inverter.

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.

The OLEV bus is an electric vehicle that can be charged while stationary or driving. 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.

Moreover, if the primary and secondary coils are vertically misaligned by a distance over 3mm, the power efficiency drops greatly. Power cables are wrapped around the center of the fish bone structures to make the “primary coils”.

Views Read Edit View history. There is a receiving device installed on the underbody of the OLEV that converts these fields into electricity.

ONLINE ELECTRIC VEHICLE (OLEV)

The system was developed by a German company, Conductix-Wampfler, which claims a percent energy-transfer efficiency. Wireless transfer was first demonstrated by Nikolai Tesla in Use dmy dates from May The wireless transfer system means that batteries in electric vehicles can be reduced in size to about a third of that you would normally expect to find in an electric car.

A wireless parking charge system on display at a motor show [Image source: 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.

Another advantage of this system is that it can also discharge power on to the oleg power grid. This is accomplished by solving technological issues that limit the commercialization of electric vehicles such as price, weight, volume, driving distance, and lack of charging infrastructure.

This approach is increasingly being tested in various countries as a potential means of charging EVs on the move. Alongside innovative battery technology, another potential method for charging electric vehicles EVs could be wireless energy transfer strips installed on road surfaces.

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.

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.

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