[[Electric road]]s power and charge [[electric vehicle]]s while driving. Sweden has tested electric road systems that charge the batteries of trucks and [[electric cars]], and among the tested systems are two ground-level power supply systems tested since 2017, in-road rail by Elways-Evias and on-road rail by Elonroad.<ref name="TRL">{{citation|url=https://trl.co.uk/sites/default/files/PIARC%20ERS%20Academy%20Report%20PPR875_Final%20Version.pdf|title=Electric Road Systems: a solution for the future|author1=D Bateman|author2=D Leal|display-authors=1|publisher=[[Transport Research Laboratory|TRL]]|date=October 8, 2018|pages=146–149|access-date=June 30, 2021|archive-date=August 3, 2020|archive-url=https://web.archive.org/web/20200803034309/https://trl.co.uk/sites/default/files/PIARC%20ERS%20Academy%20Report%20PPR875_Final%20Version.pdf|url-status=dead}}</ref> Elonroad later developed an in-road rail system for highway use at speeds up to {{convert|130|km/h|mph}}.<ref name="Corot2023"/> The systems were found to be more economical than the tested overhead line system and [[Inductive charging#Dynamic charging|dynamic inductive charging]] system. The in-road rail system is planned to deliver up to 800&nbsp;kW per vehicle traveling over a powered segment of the rail, and the system is estimated to be the most cost-effective among the four tested systems. The new systems are expected to be safe, with segments of the rail being powered only when a vehicle is traveling over them.<ref name="trafikverket-2021-02-01">{{citation |url=https://www.trafikverket.se/om-oss/pressrum/pressmeddelanden/Nationellt/2021/2021-02/trafikverket-rekommenderar-elvag-i-kombination-med-stationar-laddning/ |title=Analysera förutsättningar och planera för en utbyggnad av elvägar |publisher=[[Swedish Transport Administration]] |date=February 2, 2021|pages=21–23, 25–26, 54}}</ref> The rails have been tested while submerged in salt water and were found to be safe for pedestrians.<ref>{{citation|url=https://www.theguardian.com/environment/2018/apr/12/worlds-first-electrified-road-for-charging-vehicles-opens-in-sweden|title=World's first electrified road for charging vehicles opens in Sweden| work=[[The Guardian]]|author=Daniel Boffey|date=April 12, 2018}}</ref>
