These requirements cover electrical energy storage assemblies (EESAs) such as battery packs and combination battery pack-electrochemical capacitor assemblies and the subassembly/modules that make up these assemblies for use in light electric-powered vehicles (LEVs) as defined in this outline of investigation. This outline of investigation does not evaluate the performance or reliability of these devices. This outline of investigation does not include requirements for the evaluation of EESAs intended for use in electric vehicles@ such as on-road passenger vehicles intended for use on public roadways including highways and heavy duty off road vehicles such as battery powered ride-on industrial trucks@ which are covered under the Standard for Batteries for Use in Electric Vehicles@ UL 2580. This outline of investigation does not include requirements for evaluation of EESAs intended for use in light electric rail (LER) applications@ which are covered under the Standard for Batteries for Use in Light Electric Rail (LER) and Stationary Applications@ UL 1973.
