The test stretch on the E16 is two kilometers long. The technology is similar to light rail, with contact lines 5.4 meters over the roadway. The truck has a pantograph on the roof that feeds 750 VDC to the truck’s hybrid electric system. The current conductor can connect automatically at speeds up to 90 km/h (56 mph). The test stretch is equipped with posts 60 meters apart that hold up the electric lines over one of the lanes.

Sweden inaugurated a test stretch of electric road on the E16 in Sandviken, thus becoming one of the first countries to conduct tests with electric power for heavy transports on public roads.

At a rest area, there is a transformer for low-voltage direct current of the same type as in the light rail network. Other traffic on the road will not be affected.

Electric roads will bring us one step closer to fossil fuel-free transports, and has the potential to achieve zero carbon dioxide emissions. This is one way of developing environmentally smart transports in the existing road network. It could be a good supplement to today's road and rail network. —Lena Erixon, Director General of Trafikverket, the Swedish Transport Administration

An electrified road is one in which the electricity supply for vehicle propulsion is continuously supplied in order to keep the vehicle moving and to avoid recharging requirements. There are three possible techniques known today:

An overhead conductive technique from above (e.g., like a trolley);

An inductive technique installed under the pavement; and

A conductive technique from a rail in the pavement.

The technologies for electric roads have developed rapidly over the last few years, and are now mature enough that some of them can be tested. Last year, the Swedish Transport Administration, in consultation with Vinnova and the Swedish Energy Agency, decided to give support to two test facilities. The two systems differ as to how electric power is transferred to the heavy vehicles.

The test on the E16 in Sandviken is being carried out by Region Gävleborg, and involves a pantograph on the roof of the truck cab feeding the current down to a hybrid electric motor in the truck.

Outside Arlanda, the eRoadArlanda consortium company will test a technology that involves an electric rail in the roadway charging the vehicle during its trip. For the time being, the work will take place on a closed-off road, but the plan is that the technology will be demonstrated in actual traffic next year.

The tests will continue up through 2018. They will provide knowledge of how electric roads work in practice, and whether the technology can be used in the future. The experiment is based on the Government’s goal of energy efficiency and a fossil fuel-free vehicle fleet by 2030, and will contribute to strengthening Sweden’s competitiveness.

Three government agencies are partially funding the project, and the participants are paying for the rest of the funding:
