UL 2271:2013 free download Batteries for Use In Light Electric Vehicle (LEV) Applications
1 Scope
1 .1 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 standard.
1 .2 This standard does not evaluate the performance or reliability of these devices.
1 .3 This standard 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 / ULC-S2580.
1 .4 This standard 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) Applications and Stationary Applications, UL 1 973.
2 Components
2.1 Except as indicated in 2.2, a component of a product covered by this Standard shall comply with the requirements for that component. See Annex A for a list of Standards covering components generally used in the products covered by this Standard. A component shall comply with the Standards of CSA or UL Standards as appropriate for the country where the product is to be used.
2.2 A component is not required to comply with a specific requirement that:
a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard; or
b) Is superseded by a requirement in this standard.
3 Units of Measurement
3.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. The values given in SI (metric) units shall be normative.
4 Undated References
4.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard.
5 Reference Publications
5.1 Throughout this standard, the CSA and ULC standard references apply to products intended for use in Canada, while the UL standard references apply to products intended for use in the United States. Combined references are commonly separated by a slash (″ / ″).
5.2 The following standards are referenced in this standard, and portions of these referenced standards as identified in this standard may be essential for compliance.
