Swedish Self-charging Roads


The world’s first self-charging electric rail has been implemented into a Swedish road.
The electric rail, about 2km (1.2 miles) long has been embedded in a public road near Stockholm.
Sweden’s target of independence from fossil fuels by 2030 requires a 70% reduction in the transport sector.
The technology behind the electrification of the road linking Stockholm Arlanda airport to a logistics site outside the capital city aims to solve the thorny problems of keeping electric vehicles charged, and make the manufacture of their batteries affordable.
Energy is transferred from 2 tracks of rail in the road via a moveable arm attached to the bottom of the vehicle. The design is not dissimilar to that of a Scalextric track, although if the vehicle should overtake, the arm is automatically disconnected.
The electrified is divided into 50m sections, with an individual section powered only when a vehicle is above it.
In Sweden there roughly are half a million kilometres of roadway, of which 20,000km are highways. “If we electrify 2000km of roads that will definitely be enough” Sall said. “The distance between 2 highways is never more than 45km and electric cars can already drive that distance without
needing to be recharged. Some believe it will be enough to
electrify 500km”
