Introduction
This document is written in the frame of the standardization of one the families of Electric Road Systems that
are developed to reduce carbon dioxide and other emissions caused by road traffic (see description in
Annex A).
This document is limited to the infrastructure part of the conducted ground-based feeding ERS family and
contains requirements for all types of these systems.
The infrastructure of the dynamic electric power supply is in charge, as described in Figure A.2, to transform
the electricity from the grid and to transfer it safely to the road vehicles via metallic segments installed at road
level. The on-board part of the ERS described in Figure A.2 is dealt with in CLC/TS 50717:2022. ERS
solutions for dynamic supply of road vehicles need to be standardized to allow for interoperable, international
vehicle operation.
