Batteries for Use in Stationary and Motive Auxiliary Power Applications
1.1 These requirements cover battery systems as defined by this standard for use as energy storage for
stationary applications such as for PV, wind turbine storage or for UPS, etc. applications. These systems
shall be installed in accordance with NFPA 70, C22.1, or other applicable installation codes.
1.2 These requirements also cover battery systems as defined by this standard for use in light electric
rail (LER) applications and stationary rail applications such as rail substations. These systems are
intended for installation within either the rail car or within a sheltered stationary location such as a rail
substation. These battery systems may utilize regenerative braking from the trains as a source of energy
for recharging and are intended for direct or indirect connection to the rail power lines. These battery
systems are intended for balancing loads during peak hours, serving as an energy storage device during
regenerative breaking of the trains, and as a source of emergency power to move trains to the nearest
station during power outages.
1.3 These requirements are also applicable to batteries for use in vehicle auxiliary power (VAP) systems
that are utilized in recreational vehicles and other vehicles to provide power for various applications such
as lighting and appliances. These batteries are not used for traction power in the vehicles, since batteries
for traction power are to be evaluated to UL/ULC 2580 and UL/ULC 2271 as applicable to the intended
1.4 Annex B of this standard includes requirements specific to sodium-beta type technologies. Annex C
of this standard includes requirements specific to flowing electrolyte technologies. Annex H of this
standard includes requirements specific to vented and valve regulated lead acid and nickel cadmium
batteries. Annex I of this standard includes requirements specific to mechanically recharged metal-air
1.5 This standard evaluates the battery system's ability to safely withstand simulated abuse conditions.
This standard evaluates the system based upon the manufacturer's specified charge and discharge
1.6 This standard does not evaluate the performance (i.e. capacity measurements under various
discharge conditions) or reliability (i.e. capacity measurements under various environmental conditions) of
