This document specifies the infrastructure part defined in Figure 1 and Figure A.2 of the conducted ground based feeding systems and their interfaces. The charging infrastructure can be used for charging all road vehicle types at standstill or in motion. This document covers the following aspects: interaction between the ground based feeding systems and ERS vehicles; electrical safety and stray current protection (in case of DC electric traction power supply systems); environmental requirements; validation requirements. This document defines the interfaces between: the ground based feeding system and the grid; the infrastructure of the ground based feeding system and the on-board current collector devices of the vehicles including the specificities according to the different interface types. This document is not applicable to the on-board part of the conducted ground based feeding systems. This document is not applicable to motorcycles (including tricycles and quadricycles). This document is not applicable to vehicles or electric buses with dynamic or static inductive charging systems and related power supplies. This document is not applicable to vehicles or electric buses with dynamic or static conductive charging systems through overhead lines. This document does not apply for charging stations with only a plug-in solution.
