Standards Development
This part of the IEC 62973 series applies to lead acid batteries used for auxiliary power supply systems on rolling stock of railway. It’s an extension of Part 1 which specifies common requirements for all battery technologies. 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. Charging systems (e.g. LVPS, converters, etc.) are excluded from the scope of this document.
This document also describes the design, operation parameters, safety recommendations, routine and type tests, as well as marking.
This document is used in conjunction with IEC 60254-1,IEC 60896-21 and IEC 60896-22.
Specific requirements on subcomponents within the battery systems are covered in this document.
When there is an existing IEC standard specifying additional test conditions and requirements for lead acid batteries used in specific railway applications and which conflicts with this standard, the later takes precedence.
The main objective of this document is to achieve standardization of lead acid batteries for railway application in rolling stock for auxiliary power supply systems.
