DANSK DSF/PREN IEC 62973-2 PDF

This part of IEC 62973 applies to NiCd rechargeable battery technologies for auxiliary power supply systems used on railway vehicles. It is an extension of Part 1 which specifies common requirements for all battery technologies of other Parts. Unless otherwise specified, the requirements of Part 1 apply. Battery systems described in this document are used in conjunction with onboard charging systems of rolling stock, as described in IEC 62973-1:2018. Charging systems (e.g. LVPS, converters, etc.) are excluded from the scope of this document. This document also specifies the design, operation parameters, safety recommendations, routine and type tests, as well as marking and designation. This International Standard is used in addition to the IEC 60623:2017 or IEC 62259:2004 for NiCd Cells. Specific requirements on subcomponents within the battery systems are covered in this document, e.g. temperature measurement components. When there is an existing IEC standard specifying additional test conditions and requirements for NiCd batteries used in specific railway applications and which conflicts with this document, the latter takes precedence. The main objective of this Document is to achieve standardization of the electrical interfaces by considering NiCd battery parameters to allow for calculating the NiCd battery capacity required for a specific load profile.
