[26] [27] A working group of the French Ministry of Ecology considers rail ground-level power supply technology to be the most likely candidate for electric roads. [28] The first standard for electrical equipment on board a vehicle powered by a rail electric road system (ERS), CENELEC Technical Standard 50717, has been approved in late 2022. [ 29 ]
The patented energy absorption D-BOX technology allows coupling at speeds of up to 15 kilometres per hour (9 mph) with no structural damage, and up to 36 kilometres per hour (22 mph) with deformation but with the vehicles remaining on track. The patented D-REX system provides Ethernet high speed data connection at speeds of 100 Mbit/s.
