UL 1973 OUTLINE
OUTLINE OF INVESTIGATION FOR BATTERIES FOR USE IN LIGHT ELECTRIC RAIL (LER) APPLICATIONS AND STATIONARY APPLICATIONS
|Publication Date:||6 October 2010|
These requirements cover batteries for use as energy storage for stationary applications such as for PV, wind turbine storage or for UPS, etc. applications.
These requirements also cover light electric rail (LER) applications and stationary rail applications such as rail substations. These batteries are intended for installation within either the rail car or within a sheltered stationary location such as a rail substation. These batteries may utilize regenerative braking from the trains as a source of energy for recharging and are intended for direct connection to the rail power lines. These devices 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.
This outline of investigation evaluates the battery's ability to safely withstand simulated abuse conditions. This outline of investigation evaluates the battery based upon the manufacturer's specified charge and discharge parameters.
This outline of investigation does not evaluate the performance or reliability of these devices.
