Swedish Transport Administration electric road program
[7][8]: 21–24 Alstom, Elonroad, and other companies have, in 2020, begun drafting a standard for ground-level power supply electric roads.
[11] Shortly afterward, a working group of the French Ministry of Ecology recommended adopting a European electric road standard formulated with Sweden, Germany, Italy, the Netherlands, Spain, Poland, and others,[12] while leaning toward rail ERS, though the specific rail technology has yet to be standardized.
[19][20] A report by Research Institutes of Sweden (RISE) recommends that Stockholm County choose the stationary and dynamic charging standards selected by Trafikverket.
[22] The Swedish National Road and Transport Research Institute (VTI) similarly recommends a system capable of delivering 300 kW per truck.
[12]: 25 The final report of the second Swedish-German research collaboration on electric road systems, CollERS 2, advised Trafikverket to select a single ERS technology, suitable for heavy trucks, with several suppliers who use an existing standard, coordinated with German and French ERS decisions, not necessarily led by the European Union but with their coordination, utilizing an ERS-technology-neutral payment system.
[3]: 40 The schedule was accelerated in October 2020, when the Swedish government charged a commission with investigating the standardization, construction, operation, maintenance and financing of electric roads in Sweden.
[26] A report generated by TRL in association with the Swedish Transport Administration listed available electric road systems, of which KAIST OLEV, Siemens eHighway, Elways, Elonroad, Bombardier PRIMOVE, and Electreon were estimated to be the most commercial-ready, with OLEV and eHighway already possessing a complete system in 2018.
A 2-kilometre stretch of the E16 motorway was fitted with trolley wires 5.4 metres above its surface, which supply power at 750 volts DC.
Trolleytrucks can connect the power pickups, mounted on mechanical arms or trolley poles, while driving under the wires.
A 2-kilometre stretch of the 893 road between Arlanda airport cargo terminal and the Rosersberg logistics area was fitted with embedded conductor rails as part of the eRoadArlanda project.
[34] Trafikverket assessed a wireless electric road system (WERS) with inductive coils using technology by Electreon, an Israeli startup.
[35] The system is made of short sections containing copper coils that energize when a vehicle is driving over them and switch off when it's passed, and it supports power metering and a billing for the energy consumed.
[37] The pilot was scheduled to conclude in March 2022,[38] however Electreon has requested an extension for another year[39] so it can test receivers nominally capable of 30 kW.
[41] The German Ministry of Economy, BMWK, tested infrastructure by Electreon in 2023 with a bus equipped with inductive coils that receive power from a 200-meter strip of transmitters under the road surface.
[42] The Coventry University dynamic charging project DynaCoV found wireless electric roads financially infeasible, using itemized costs provided in 2021 by Electreon.
[43] Trafikverket began testing ground-level conductive rails power delivery in 2020 using technology by Elonroad, a Swedish startup located in Lund.
The system uses a conductive pickup under the vehicle that connects to a rail on top of the road surface via sliding contacts.
The system as tested is capable of delivering up to 300 kW with 97% efficiency while driving[45] and it is estimated to have a maintenance period of 10 years.
[28] The project's final report submitted in December 2024 recommended against a national electric road network in Sweden as it would not be cost-effective.
The commission investigated the electrification of heavy transport vehicles, fast charging, and the standardization, construction, operation, maintenance and financing of electric roads in Sweden.
[63]: 10–11 ABB formed a consortium that will handle the different aspects of the business model, such as energy metering and billing, for its ground-level power supply technology.
[64][65] The Swedish Transport Agency has been tasked with proposing a technical, financial, and legal framework for the electric road toll system by November 1, 2022.
[67][68] The Swedish Transport Administration announced on July 1, 2021, that a section of the E20 route was chosen to be the first permanent electric road in Sweden.
[23] The Swedish Transport Agency has proposed in late 2022 the billing framework for the first permanent electric road, which will initially rely on a permit for a fixed fee.
