Which Version is Right for You?
IEC-62133 is one of the most important standards for exporting lithium-ion batteries, including those used in consumer products, IT equipment, tools, laboratory, household and medical equipment. There are currently two different versions of standard, IEC 62133 2nd Edition and IEC 62133-2 1st Edition. While these names certainly look to the be same, the standards are different. U.S and Canadian standards are harmonized to IEC 62133 2nd Edition, whereas the EU has adopted 62133-2 1st edition, with an effective date of March 14, 2020. After this date, all new battery systems will be certified according to IEC 62133-2, 1st Edition. Existing batteries will not need to be re-certified unless there is a design change. What is the difference between the two standards and how can you determine which is best for you?
Some (but not all) of the changes in IEC 62133-2 1st Edition include:
Regarding the inclusion of single fault conditions, the concept of should vs shall must be taken into consideration. Under the standard, external short circuit should be performed with single fault condition; however, batteries are typically components of larger systems, not standalone devices, meaning redundancy may be implemented at a system level. This does not mean you can ignore this requirement, but you do not need to comply exactly as written.
While it is anticipated that the US and Canada will adopt IEC 62133-2 1st Edition within the next two years, without a firm deadline, it can be difficult to determine which standard to use today. Ultimately, you must consider the market you choose to enter and the end product. The end product's requirements will determine component requirements, which includes the battery. This is true regardless of existing certifications. As such, the end product may prescribe additional requirements or specific versions of battery standards. When in doubt, consult with experts who can help you determine your best path forward.
