Annotation

This European Standard specifies rechargeable lead acid and NiCd-batteries for 110 V voltage auxiliary power supply system for railway vehicles.

This European Standard may be applied to other rolling stock types (e.g. light rail vehicles, tramways, metros...) if these are not in the scope of another specific standard.

Others technologies like NiMh or Lithium are not covered by this standard at present.

This European Standard focuses on:

- the description of mechanical interfaces: dimensions of the cells or monobloc batteries, main terminals and preferred sizes of the mounting space of the battery systems for lead acid batteries,

- the description of mechanical interfaces: dimensions of the trays and main terminals for NiCd batteries (as they have different characteristics depending on the technology),

- description of electrical interfaces: capacity, voltage and charging characteristic.

This European Standard restricts the variety of different types provided by EN 60254 and EN 60896 for lead acid batteries and defines the use of cells compliant to EN 60623 and EN 62259 for NiCd-Batteries.

The main objective of this standard is to achieve interchangeability of the battery cells and monobloc for lead acid batteries and the interchangeability of the battery trays for NiCd batteries.
