CEI EN 50547

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.
