The pickup behind the car automatically finds the current bar. When overtaking release the rail temporarily.
– To electrify the Swedish road network is no problem. We can put a rail in the roadway in miles per hour. In one year, we can electrify the main roads in the country, said Peter Knutsson at NCC Roads.
Elways technology for electrification, with a splint in the roadway and a pickup in the vehicle, is one of those who received support from the Swedish Energy Agency for more research. Competing technologies are overhead with pantographs on trains or trams, and inductive charging, where the vehicle and the power source does not need to be in contact.
For Gunnar Asplund, the engineer behind Elways, is the logic behind a rail in the path clear:
– Overhead Lines works only for trucks and buses. Cars need a pantograph that lasts six feet in the air. Inductive charging from roadway is very fun to work with, but it is five to ten times as expensive as this technology, he said.
Elways technology is said to cost between five and ten million per kilometer of road. Consortium Elways has since 2012 conducted tests on 200 meter test track on the road between the airport and the freight terminal in Rosersberg.
The test distance shall be extended to 2 000 meters, and at the end of 2015 would be tested with real traffic. An electric truck will then carry cargo on the route.
– We would like to continue to electrify the whole of Sweden. Yes, Europe. Technically there is no problem. We mills a 15 cm deep rut in the road, lay down and seal the rail. We have developed a molding compound that holds at least 20 years. We can assemble the track at a speed of one kilometer per hour elväg said Peter Knutsson.
– It’s kind of like putting up a lighting network. First, a linear work: to mill down the rail of the roadway. Since a transverse work, they must have the connection for dewatering and force every fifty yards.
