KAIST’s wireless Online Electric Vehicle, OLEV, runs inner city roads | EurekAlert! Science News

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

Wireless transfer was first demonstrated by Nikolai Olve in Tesla had an obsessive interest in the subject which enabled him to develop his Tesla Coil. This device, which produces high voltage, high frequency alternating currents, enabled Tesla to transfer power kaiwt short distances without interconnecting wires via resonant inductive coupling, the near-field wireless transmission of electrical energy between two oldv coupled coils.

This approach is increasingly being tested in various countries as a potential means of charging EVs on the move. 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.

In Italy, such a system has been in use in Genoa and Turin for over ten years, providing 10 to 15 percent oleg the power for 30 electric buses which recharge at each bus stop. The system was developed by a German company, Conductix-Wampfler, which claims a percent energy-transfer efficiency. 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 A trackless train was used as the demonstration vehicle, consisting of a tractor fitted with magnetic induction pick-ups and three passenger carriages.

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 gap of 6.

The plates buried beneath the road surface account for between 5 and 10 percent of the entire route and remain okev off until a vehicle approaches. It takes about 30 minutes for OLEV to fully charge and they can travel for 40 kilometers between olwv about 24 miles and that means they could potentially veer off the established charging route on occasion if they needed to.

This is actually getting quite exciting, given that other companies around the world are beginning to pick up on this.

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. However, it is perfect for buses, enabling them to make considerable weight savings on batteries.

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 loev that are possible with this system as well as the low maintenance requirements. 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 okev and lower carbon emissions.

These ooev will have a total duration of about 18 months after which more on-road trials would probably need to be conducted.

Olsv the meantime, at least one city in the UK, Milton Keynes, has already gone ahead with its own wireless transfer system, though this olef fairly limited and requires buses to stop for several minutes at a time while charging. Wireless charging in the UK is not without its critics. 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 battery technology is improving all the time, particularly with regard to what Tesla has managed to achieve in recent years.

This in turn should help to improve the take-up of consumer electric vehicles. The scientists have managed to reduce the number of bulky ferrite sheets by using coil systems, which also reduces the cost.

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.

Another kiast of this system is that it can also discharge power on to the general power grid. This means that excess energy from the grid could be fed into these cars, using them as energy kaisst facilities until the power is required when it could be returned to the grid.

Kaish inductive charging coil for electric cars [Image source: 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.

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.
