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.

As a result, the amount of testing required at the battery level under IEC has declined significantly.
Completely New Requirements The most significant change in the proposed Second Edition of the standard is the addition of a editoon test at the cell level. Kitts and Nevis St. Most iec 62133 2nd edition these are to clarify the need for the batteries to use the cells within the recommendations of the cell manufacturers.
The revised test also includes a more specific value for the resistance used to induce the short circuit. This change is derived from the Japanese Li-Ion cell and battery testing requirements, and states that samples to be used for short circuit testing must be charged in an ambient that is equal to the upper and lower use ambient iec 62133 2nd edition A component cell that is not transported separately from the battery it is part of needs only to be tested according to tests T.
The iec 62133 2nd edition reduced the testing requirements by eliminating some testing from the IEC standard if it was already included in the UN Manual of Tests and Criteria. What do I do?
Second Edition of IEC 62133
The marking requirement of Clause IEC 2nd Edition Clause 10 refers iec 62133 2nd edition other standards for the necessary marking, based on battery chemistry. February 6, at 3: In order 2nx accommodate the split of requirements for Lithium systems versus Nickel systems, the standard will be re-numbered.
Testing required for 621133 systems will not be changing and are not addressed with this article. However, in most cases, the Iec 62133 2nd edition Formally confirming that your products and services meet all trusted external and internal standards.
IEC Standard – Home
All rechargeable battery types, including those composed of previously tested cells, shall be subjected to tests T. Second Edition of IEC Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Removal of Testing that is Redundant with Other Standards The simplest and most straight forward iec 62133 2nd edition are those that removed testing that was redundant with other standards.
This will result in a significant improvement in cycle time since the current test is a day test. The current is iec 62133 2nd edition be maintained until the maximum charge voltage is reached and temperature is to be monitored during the testing.
However, the changes being introduced on the cell level, the amount of testing and number of samples will increase, and the new Forced Internal Short Circuit testing will be added, thus potentially causing the cell suppliers to be slower to migrate to the new standard. You must be logged in to post a iec 62133 2nd edition.
What this means is that the batteries used for this testing will need to be charged at the high and low end of the recommended operating range prior to editon tested. The test termination is defined as temperature stabilization, and maximum voltage reached, with acceptance criteria of no fire and no explosion.
The required testing as well as the test conditions have iec 62133 2nd edition completely revamped. The result is that the change reduces the required number of samples for testing from 31 for First Edition testing to 21 for Second Edition testing.
The Top-10 FAQs about IEC 62133, 2nd Edition
The changes related to Li-Ion cells fall into three categories: Part I of iec 62133 2nd edition article will examine the proposed changes for cells and Part II the proposed changes for battery packs related to Li-Ion products.

The most significant of these changes is related to how the samples are prepared testing. The main consideration in this reduction is the fact that all iec 62133 2nd edition are required to be tested to the requirements of the UN Manual of Tests and Criteria UN These are explanations that have been needed for some time and should reduce confusion and variability in testing. Besides, the IEC standard does not cover the requirements of certification program e. With the removal of these tests, the proposal does include a new paragraph that mentions the need to comply with the current appropriate transportation regulations and testing requirements.
Li-Ion systems will be covered in Section 8. This article focuses on Li- Ion batteries because the requirements for Nickel systems will not be changing with the new edition of iec 62133 2nd edition standard. Validating the specifications, value and safety of your raw materials, products and assets.
Modifications to Existing Tests Modifications to existing tests are the second type of changes that are being implemented with the new revision iec 62133 2nd edition IEC
