IEC 62133 2ND EDITION PDF

The Top FAQs about IEC , 2nd Edition. The 2nd Edition of IEC was published in December, but our Intertek battery experts continue to. As the industry transition from UL to IEC began in June, , Intertek is positioned to serve the needs of lithium ion battery manufacturers who are. Second Edition of IEC The Standard for Secondary Cells and Batteries Containing Alkaline or Other Non-Acid Electrolytes is in its Final Review Cycle.

Battery Technologies Get an overview of current battery technologies and where the market is moving. As the title of the test implies, the intent is to induce an internal short circuit within the jellyroll of the cell. Following the placement of the particle, the affected jellyroll is to be crushed. 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.

Auditing Consulting Sourcing Training. You must be logged in to post a comment. IEC 2nd edition referenced the UN The test procedure very explicitly describes a method that requires the test facility to fully charge a Li-Ion cell, then open eidtion and remove the jellyroll.

IEC is the most important standard for exporting Lithium-Ion batteries, including those used in IT equipment, tools, laboratory, household and medical equipment.

This section presents the procedures to be followed for the classification of lithium metal and lithium ion cells and batteries 2n UN Nos. Auditing Consulting Sourcing Training.

Understanding IEC 62133 Standard

Problems for some cells that previously passed testing with a lower resistance circuit may emerge editioh this tighter range can 62133 a softer shorting of the cell and result in a more eventful outcome. 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.

The changes related to Li-Ion cells fall into three categories: To provide a better user experience, our site uses cookies. The Deition Edition will have some very significant changes for Li-Ion cell and battery manufacturers.

If the charger maximum voltage is not known, a value of 5 V per cell iev cell string will be used. It allows for the fact that these requirements may change over time and permits for presentation of customer documentation to verify compliance.

All of this is to be done under very specific environmental and time constraints to avoid drying of the jellyroll. The test termination is defined as temperature stabilization, and maximum voltage reached, with acceptance criteria of no fire and no explosion.

All rechargeable battery types, including those composed of previously tested cells, shall be subjected to tests T. 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.

In this article we will review the significant changes related to Li-Ion cells. Download 2nc technical paper.

Most of these are to clarify the need for the batteries to use the cells within the recommendations of the cell manufacturers. However, in most cases, the UN Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.

The current is to be maintained until the maximum charge voltage is reached and temperature is to be monitored during the testing. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.

Global Reach Intertek is the industry leader with over 43, people in 1, locations in over countries. The new revision of IEC is expected to be issued in early In addition, rechargeable single cell batteries with overcharge protection shall be subjected to test T.

Testing required for Nickel systems will not be changing and are not addressed with this article. The section for cells in the second edition has been modified to include only one test temperature, and to provide a tighter range for the resistance of the circuit.

Battery Power Online | Second Edition of IEC

The revised test also includes a more specific value for the resistance used to induce the short circuit. The marking requirement of Clause IEC 2nd Edition Clause 10 refers to other standards for the necessary marking, based on battery chemistry. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. The testing that has been completely removed as a result of this review is: Cookies on UL Accept To provide a better user experience, our site uses cookies.

This test is performed on a fully discharged set of five batteries and charges the batteries with a current of two times the rated current and an upper voltage limit that is set to the maximum voltage available from the charger to be used with the battery. Reduced Sample Requirement The sub-committee took a more holistic look at the testing required for Lithium Ion batteries than in the past. Nickel system requirements will be covered in Section 7 of the new standard.

It is very complicated and has questionable repeatability. Your email address will not be published.

Evaluating how your products and editlon meet and exceed quality, safety, sustainability and performance standards. Testing and requirements will actually be reduced for Li-Ion battery manufacturers. This change makes perfect sense because the UN November 9, at As the industry transition from UL edigion IEC began in June,Intertek is positioned to serve edution needs of lithium ion battery manufacturers who are bringing products to market globally.

Additionally, a termination criteria of 10 percent deformation of the cell has been added. February 6, at 3: 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 being tested.
