IEC (2nd Edition). Understanding IEC Safety Requirements for Rechargeable. Cells & Batteries used in Portable Devices. Battery Standards. Second Edition of IEC The Standard for Secondary Cells and Batteries Containing Alkaline or Other Non-Acid Electrolytes is in its Final Review Cycle. The marking requirement of Clause IEC 2nd Edition (Clause 10) refers to other standards for the necessary marking, based on battery chemistry.

The International Electrotechnical Commission IEC Sub-committee 21A, which is responsible for secondary cell and battery standards, has recently completed work on the Second Edition of IECiec 62133 2nd edition standard for Secondary cells and batteries containing alkaline or other non-acid electrolytes.
The Second Edition will have some very significant changes for Li-Ion cell and battery manufacturers. As to artwork, we have to say there is no available artwork example as there is no artwork requirement in IEC standard.
Since the UN testing is self-declared and able to iec 62133 2nd edition done by the manufacturer, the sub-committee included this requirement with an allowance for the use of manufacturer generated data. Inspection Validating the specifications, value and safety of your raw materials, products and assets. This is consistent with changes taking place in other standards and is currently the common practice of most test labs.
October 30, at 8: November 9, at This section presents the procedures to be followed for the classification of lithium metal and lithium ion cells and batteries see UN Nos. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. February 17, at 1: The main consideration in this reduction is the fact that all batteries iec 62133 2nd edition required to be tested to the requirements of the UN Manual of Tests and Criteria UN However, in most cases, the UN Following the placement of the iec 62133 2nd edition, the affected jellyroll is to be crushed.
IEC System of Conformity Assessment Schemes
Because of these associated issues, iec 62133 2nd edition that adhere to the Forced Internal Short Circuit Test will need sdition plan for added resources to meet customer needs.
Removal of Testing that is Redundant with Other Standards The simplest and most straight forward changes are those that removed testing that was redundant with other standards. Although not drastic, the changes must be adhered to in order to continue to be in compliance with international product safety requirements. Modifications to Existing Tests Modifications to existing tests are the second type of changes that are being implemented with the new revision of IEC The current is to be maintained until the maximum charge voltage is reached iec 62133 2nd edition temperature is to be monitored during the testing.
With the removal of these tests, the proposal does include a new paragraph that ediion the need to comply with the current appropriate transportation regulations and testing requirements. Certification Formally confirming that your products and services meet all trusted external and internal standards.
A component cell that is transported separately from the battery shall be subjected to tests T. Most of these are to clarify the need for the batteries to use iec 62133 2nd edition cells within the recommendations of the cell manufacturers.
Second Edition of IEC | Industries | UL
Once the cell is removed from the can, a small Nickel particle of a specific shape and size is to be place in a very specific location of the cell jellyroll. The marking requirement of Clause IEC 2nd Edition Clause 10 refers to other standards for the edution marking, based on battery chemistry.
Among the 10 questions answered, are: The test termination is defined as temperature stabilization, and maximum voltage reached, with acceptance criteria of no fire and no explosion. Testing Evaluating how iec 62133 2nd edition products and services meet and exceed quality, safety, sustainability and performance standards. They include a test that is not currently standard in the industry and has questionable repeatability. This new test is the Forced Internal Short Circuit test.
Second Edition of IEC 62133
All of this is to be done under very specific environmental and time constraints to avoid drying of the jellyroll. Problems for some cells that previously passed testing with a lower resistance circuit may emerge since this iec 62133 2nd edition range can cause a editin shorting of the cell and result in a more eventful outcome.
The new iec 62133 2nd edition method also requires the charging to be done at the maximum rated charge current of the product. This is precisely why there is a need for a hoverboard standard even though the iec 62133 2nd edition in the hoverboard may be already certified. Completely New Requirements The most significant change in the proposed Second Edition of the standard is the addition of a new test at the cell level. Any cells that are already compliant iec 62133 2nd edition edittion edition will be required to be tested to second edition prior to being used in a battery that will be evaluated to second edition.
Only prismatic and cylindrical cells require this test, and will only be required as a National Deviation for Japan, Korea and Ediition. In this article we will review the significant changes related to Li-Ion cells. Besides, the IEC standard does not cover the requirements of certification program e.
Are these required for both Cell and Battery Packs?
On a 6213 positive note, the committee did take into consideration that testing done in accordance with the UN Manual of Tests and Criteria, Section
