Railway applications - Fixed installations - Interface requirements between charging infrastructure with dedicated contact line sections and electric traction units with onboard energy storages and current collectors CLC/prTS 50729

Scope

This document specifies interface requirements between charging infrastructure with dedicated contact line sections and electric traction units with onboard energy storages and current collectors.
The dedicated contact line section can be
- separated from other contact line systems of electrified railway lines and fed separately or
- connected with contact line systems of electrified railway lines.
The charging infrastructure can be used for charging the trains at a standstill and/or for charging the trains
during the traction phases.
This Technical Specification does not apply for charging stations with a plug-in solution.
This Technical Specification covers the following aspects:
- supply voltages and frequencies (e.g. reference to EN 50163)
- electromagnetic compatibility (e.g. avoidance of (unacceptable) unbalances) in the feeding grid
(national 3 AC grid) (e.g. ref. to EN 50160, EN IEC 61000 series)
- interaction between the vehicle traction/charging system and the electric traction charging power
supply system (e.g. ref. to EN 50388)
- transmitting required information towards driver and/or train (TCMS, signs or similar)
- contact line system (e.g. ref. to EN 50119)
- maximum load current during standstill (e.g. ref. to EN 50367)
- contact line protection principles (e.g. ref. to EN 50633)
- electrical safety (e.g. ref. to EN 50122-1)
- stray current protection (in case of DC electric traction power supply systems, e.g. ref. to EN 50122-
2)
- protection against influence on signalling systems (e.g. ref. to EN 50238)
This Technical Specification applies to new infrastructure for charging of accumulator electric traction units.
