The Top-10 FAQs about IEC 62133, 2nd Edition
New Test A new test has also been added at the battery level intended to simulate charging the battery for a longer period edihion time than specified by the manufacturer using a high charge rate. This procedure is only required for samples that 2nv be used for the short circuit, thermal abuse, crush and forced internal short tests at the cell level.
The test procedure very explicitly describes a method that requires the test facility to fully charge a Li-Ion cell, then open it and remove the jellyroll.
Register for our free webinar About the IEC Standard IEC is the most important standard for exporting Lithium-Ion batteries, including those used in IT equipment, tools, laboratory, household and medical equipment. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
How are they handled for CB Scheme certifications? 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 bringing products to market globally.
It allows for the fact that these requirements may change over time and permits for presentation of customer documentation to verify compliance.
Although not drastic, the changes must be adhered to in order to continue to be in compliance with international product safety requirements. 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. Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world.
Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. February 17, at 1: This new test is the Forced Internal Short Circuit test. Kitts and Nevis St. This change makes perfect sense because the UN IEC 2nd edition referenced the UN Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.

Assurance Testing Inspection Certification. The new revision of IEC is expected to be issued in early The new charge method also requires the charging to be done at the maximum rated charge current of the product.
To get your copy, simply fill in the information below: Batteries The revisions in the proposed second edition of IEC will be less pronounced for battery manufacturers than those noted for cell suppliers. This article focuses on Li- Ion batteries because the requirements for Nickel systems will not be changing with the new edition of the standard.
Until 30th April,Secondary re-chargeable lithium batteries tested to UL are accepted for CB certification.
Understanding IEC Standard
In the previous edition, the requirement was only to be less than m?. You may use these HTML tags and attributes: Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. A component cell that is transported separately from the battery shall be subjected to 62133 T. Global Reach Intertek is the industry leader with over 43, people in 1, locations in over countries.

Testing and requirements will actually be reduced for Li-Ion battery manufacturers. Can you please 2nc me a sample drawing or schematic. 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 edtion be used with the battery.
All of this is to be done under very specific environmental and time constraints to avoid drying of the jellyroll. 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. A component cell that is not transported separately from the battery it is part of needs only to be tested according to tests T.
Only prismatic and cylindrical cells require this test, and will only be required as a National Deviation for Japan, Korea and Switzerland. The test termination is defined as temperature stabilization, and maximum voltage reached, with acceptance criteria of no fire and no explosion. A more significant change is the split of the short circuit into a separate section for cells and batteries.
As a result, the amount of testing required at the battery level under IEC has declined significantly.
