Sweden’s Electric Road That Can Charge Vehicles on Motion

Sweden has completed the first step of the 20,000 kilometers long electric road project. The electric road, equipped with a system called conductor charge, can charge electric vehicles on motion.

The project, eRoadland, uses the technology that connects electrical rail and vehicle, used in electric trains and buses. Assuming that electric cars with small batteries have the same cost as automobiles with internal combustion, the project, which is expected to invest about $9.5 billion, could create a revolution in the whole country in less than three years.

Thanks to the conductive rail system, the electric road that will allow charging of moving vehicles will eliminate the need for charging stations and allow vehicles to be equipped with smaller batteries. Thus, the new generation vehicles will have much lower costs and weights.

The conductors of the electric road are installed under the rail and does not contain any electrical current on the surface and therefore poses no risk of electrocution . Even if the electric road is filled with salted water, the level of electricity on the surface is 1 volt, which can be walked even with barefoot.

The electric road, which will produce 90% less emissions than alternative fossil-fueled transport, suits well to the Swedish government’s mission to develop a fossil-free transport infrastructure by 2030.
