context_page_description: An electric road, eroad, or electric road system is a road which supplies electric power to vehicles travelling on it. Common implementations are overhead power lines above the road and ground-level power supply through conductive rails or inductive coils embedded in the road. Overhead power lines are limited to commercial vehicles while ground-level power can be used by any vehicle, which allows for public charging through power metering and billing systems. Of the three systems, ground-level conductive rails are estimated to be the most cost-effective. Korea was the first to implement a public electric road with a commercial bus line in 2013 after testing an experimental shuttle service in 2009. Sweden has been performing assessments of various electric road technologies since 2013 and expects to start formulating a national electric road system in 2022 and finish planning by 2033.
context_section_description: Ground-level conductive rails were tested from 2017 to 2019, using technology by the company Elways. 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. Short sections of the rails are energized as a compatible vehicle approaches and they are disconnected once the vehicle has passed. The system measures the energy consumed, so that the vehicle owner can be billed. Busses and trucks were tested on the road, and the system is suited for electric cars, and is safe to touch even when the road is flooded with salt water. The system is capable of delivering 200kW of power and has a maintenance period of 20 years.
