Induction charging lanes

Short description (max. 250 characters)
Induction charging lanes (ICL) overcome the range limitations of electric vehicles (EV) and enable efficient long distance traveling. In conjunction with intelligent transportation systems (ITS), the dream of automated driving can turn into reality.

Key benefits (max. 250 characters)
ICLs enable efficient, sustainable and emission free transportation of people and goods over long distances on public streets by means of safe, cable free transmission of energy to EVs regardless of weather conditions or impact of vandalism.

Detailed description (max. 500 words)
Induction charging lanes will be built into highways and bus lanes of our cities.

This new way of charging batteries will be available for every vehicle with an electric or hybrid drive including trucks, busses, EVs, PHEVs (Plug-in electric vehicles) and standard hybrid cars. Vehicles can use the lane all the time or just switch to it when the charge of battery gets low. The range of EVs won't be a problem anymore.

Today, people think of electromobility as a good, green idea, but when it comes to range limitations and pricing, enthusiasm swaps. On highways ICLs are safer than overhead wires, the induction technology can be used by both, cars and trucks. Flexibility is given, vehicles can switch lanes whenever necessary. There are no charging stops needed anymore, people will be able to travel long distances with their EV. Hybrid electric trucks make tomorrow's logistics greener. In cities, ICLs for busses and trams provide new opportunities for city planners: Quiet and emission-free transportation in parks and old towns now become wireless causing higher acceptation by local residents. 
When we combine ICLs and ITS, undreamt of possibilities open up: Software always knows the busses' position and it's delay - no time wasted waiting for the bus. And because the ITS knows when the traffic lights get red, it can control the busses' acceleration and braking to make the ride even more comfortable. ITS systems enable automated driving on highways: Following the ICL, the vehicles communicate wirelessly and sensors help to measure the distance to others and can detect non-communicating vehicles and other potential risks. Intelligent software reduces superfluous accelerating and braking. Imagine the day that vehicles drive automatically on our highway without refueling, breaks for the driver, traffic jams or accidents.

This technology is the same wireless charging that works inside your electric toothbrush. It operates with an alternating current and two inductors: The primary inductor is built into the lane generating a magnetic field. About 10 cm above, the secondary one underneath the vehicle transforms it to an alternating current providing energy which is stored in batteries or immediately used for the electric motors. In our case, the primary inductor actually consists of a lot of inductors which are switch on/off by a signal coming from the passing vehicle so that the magnetic field is only generated when there is a vehicle to charge above. 

Weather influences such as Rain, Snow and Storms can't harm the system. Furthermore it's safer than the use of overhead wires: No risk someone hits a power pole or cable, no danger for a landing rescue helicopter and of course secure from metal theft and vandalism. There are no health risks due to electromagnetic fields because the field is only generated when the secondary inductor is directly above the primary one. Then 70-90% of the electric energy can be transmitted and only very little interfering fields are created.
