Editing Ground-level power supply (section)

===Standardization===
[[Alstom]], Elonroad, and other companies have, in 2020, begun drafting a standard for ground-level power supply electric roads.<ref>{{citation |url=https://www.youtube.com/watch?v=I5xdJMoz_WA  |archive-url=https://ghostarchive.org/varchive/youtube/20211222/I5xdJMoz_WA |archive-date=December 22, 2021 |url-status=live|title=Electric Road Systems - PIARC Online Discussion |author=[[PIARC]] |date=February 17, 2021 |at=34 minutes 34 seconds, 2 hours 36 minutes 51 seconds}}{{cbignore}}</ref><ref>{{citation |url=http://ri.diva-portal.org/smash/get/diva2:1540005/FULLTEXT01.pdf |title=Key Messages on Electric Roads - Executive Summary from the CollERS Project |date=March 26, 2021 |accessdate=February 11, 2022 |editor=Martin G.
