28、e This is the common UL and ULC Standard for Batteries for Use In Light Electric Vehicle (LEV) Applications. It is the First edition of both CAN/ULC-S2271 and ANSI/UL 2271. This Joint Standard was prepared by Underwriters Laboratories Inc., ULC Standards, and the Technical Committee on Batteries for
29、 Use in Electric Vehicles (EVs). The standard was formally approved by the UL/ULC Technical Committee on Batteries for Use in Electric Vehicles (EVs). The efforts and support of the Technical Committee are gratefully acknowledged. Only metric SI units of measurement are used in this Standard. If a v
30、alue for measurement is followed by a value in other units in parentheses, the second value may be approximate. The rst stated value is the requirement. In Canada, there are two official languages, English and French. All safety warnings must be in French and English. Attention is drawn to the possi
31、bility that some Canadian authorities may require additional markings and/or installation instructions to be in both official languages. Annex A and Annex B are identied as normative, as such, form mandatory parts of this Standard. Note: Although the intended primary application of this Standard is
32、stated in its scope, it is important to note that it remains the responsibility of the users of the standard to judge its suitability for their particular purpose. Level of Harmonization This Standard is published as an identical standard between UL and ULC Standards. An identical standard is a stan
33、dard that is the same in technical content except for conicts in Codes and Governmental Regulations. Presentation shall be word for word except for editorial changes. Interpretations The interpretation by the standards development organization of an identical or equivalent standard shall be based on
34、 the literal text to determine compliance with the standard in accordance with the procedural rules of the standards development organization. If more than one interpretation of the literal text has been identied, a revision shall be proposed as soon as possible to each of the standards development
35、organizations to more accurately reect the intent. UL Effective Date A UL effective date is established by Underwriters Laboratories Inc. and is not part of the ANSI approved standard.

36、STRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 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 elec
37、tric-powered vehicles (LEVs) as dened 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
38、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 EE
39、SAs 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 1973. 2 Components 2.1 Except as indicated in 2.2, a component of a product covered by this Standard sh
40、all 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
41、 A component is not required to comply with a specic 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 wit
42、hout 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 a
43、s 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.
