CSA C22.2 NO. 62133-2:20 PDF Download

CSA C22.2 NO. 62133-2:20 is a safety standard that applies to secondary cells and batteries with non-acid electrolytes, specifically lithium systems, used in portable applications. The standard is a harmonized version developed by CSA Group and UL (Underwriters Laboratories) to ensure the safe operation of these batteries.

The scope of the standard includes requirements and tests for the safe operation of portable sealed secondary lithium cells and batteries under normal and reasonably foreseeable misuse conditions. It addresses the safety considerations for these batteries during their intended use.

However, it is important to note that this standard is not suitable for evaluating the safety of end-products that use these batteries. It lacks specific requirements for factors such as charging, normal loads, abnormal conditions, and the environmental stresses encountered by the end-products. Battery packs with additional features or circuitry, including integral charging circuitry, are considered end-products and may require additional safety evaluations.

The standard has been developed in compliance with the Standards Council of Canada requirements for National Standards and has been published as a National Standard of Canada by CSA Group. It is based on the IEC (International Electrotechnical Commission) Publication 62133-2: first edition, which was issued in February 2017 and is copyrighted by the IEC.
