The future is electric with charging infrastructure and electrified roads

Our engagement and offers in charging infrastructure

NCC has built infrastructure for transport since 1875 and we naturally also intend to help build the sustainable roads of the future. We therefore have long-standing partnerships with a number of different actors in relation to charging infrastructure for electric vehicles.

Since 2011, we have been deeply involved in dynamic charging/electrified roads, largely within the framework of the eRoadArlanda and SmartRoad Gotland projects, giving us globally unparalleled expertise and experience in a new area that is capable of substantially reducing the carbon footprint of road transport.

Alongside our engagement with electrified roads, we have also built up the strategic partnerships we need in order to offer stationary charging solutions.
Overall, this means that we now hold the expertise and experience needed to deliver everything from feasibility studies, project planning and project management to groundwork and civil engineering projects for all types of charging infrastructure.

• There are two basic technologies for electrified roads: conductive (direct contact) and inductive (wireless) transmission of electricity to the vehicle.
• Examples of conductive electrified road technologies:
  
  • Elways (Sweden): A two-track rail in the road, no electricity on the surface, works for both light and heavy vehicles.
  • Alstom (France): A rail in the road, no electricity on the surface, works for both light and heavy vehicles.
  • Elonroad (Sweden): A rail on or in the road, electricity on the surface, works for both light and heavy vehicles.
  • Siemens (Germany): Overhead contact lines. Only works for heavy vehicles.
• There are various technologies for inductive transmission, including those from Electreon (Israel), Bombardier (Canada) and Qualcomm (USA).
• The conductive technologies from Elways and Siemens were the first in the world to be tested on public roads in the eRoadArlanda and Elväg Gävle projects, with the Swedish Transport Administration conducting a pre-commercial procurement. A new such procurement has now led to the technologies from Electreon and Elonroad being tested in the SmartRoad Gotland and EVolutionRoad projects.
• NCC has been and is involved in various collaborations concerning electrified roads, primarily with Elways and Electreon.

eRoadArlanda - how it works

• NCC’s eRoadArlanda project is testing a technology for electrified roads where the vehicle draws power from a rail sunk into the road.

• An arm from the truck detects when the vehicle is over the rail and docks onto it.

• The arm remains in contact with the rail for as long as the rail is beneath the truck. During overtaking, for example, the arm lifts up automatically.
