Here is a summary of what I have learned to date on the subject UL has a standard for the cells used in a battery pack UL1642 "Lithium Batteries" UL has a standard for a battery pack incorporating Lithium Ion cells UL2054 "Household and Commercial Batteries" While there does not seem to be any mandatory certs required in Europe and other countries as far as I have been able to determine there is an IEC/EN standard for battery packs EN62133 "SECONDARY CELLS AND BATTERIES CONTAINING ALKALINE OR OTHER NON-ACID ELECTROLYTES - SAFETY REQUIREMENTS FOR PORTABLE SEALED SECONDARY CELLS, AND FOR BATTERIES MADE FROM THEM, FOR USE IN PORTABLE APPLICATIONS" which can be applied to Lithium Ion batteries. I have heard rumours this standard may be adopted as a mandatory requirement by some countries in Europe and Asia but don't have any specific details... For Japan the DENAN Law was revised in November 2007 to include Lithium-ion batteries in the DENAN scope in the Non Specified Category, Other Electrical Appliances and Materials. However, the actual requirements for Lithium batteries will be published at the end of March 2008, and implemented on November 20, 2008.
It seems that Lithium batteries imported to Japan or sold in Japan after November 20 with an energy density greater then 400Watts/Liter requires a PSE Circle Mark. Lithium batteries which are in the Japanese market before November 20, 2008 may have a grace period (not announced yet by METI). The (PS)E circle mark is a quasi self declaration similar to the CE Mark so you can have testing performed by any lab capable of doing the tests to support your marking. The Japanese standards for the lithium ion batteries are JIS C8712 " Safety Requirements for Portable Sealed Secondary Cells and Batteries Made From Them for Use in Portable Applications" and JIS C8714 " Safety Tests for Portable Lithium Ion Secondary Cells and Batteries for Use in Portable Equipment" which are a modified versions of IEC62133. The biggest difference seems to be the JIS standards add a forced internal short circuit of cells test which is supposed to simulate a piece of metal damaging the separator material leading to a short circuit thermal runaway situation. C8712 does not appear to be available in English but you can get a translation of C8714 at the following site. http://www.webstore.jsa.or.jp/webstore/Com/FlowControl.jsp?lang=en <http://www.webstore.jsa.or.jp/webstore Com/FlowControl.jsp?lang=en&bunsyoId=JI +C+8714%3A2007&dantaiCd=JIS&status=1&pageNo=0> &bunsyoId=JIS+C+8714%3A2007&dantaiCd=JIS&status=1&pageNo=0 I have been advised that the C8714 standard is all you need since all the requirements of C8712 is similar to the IEC62133 standard and are repeated in the C8714 standard but I am in the process of having this verified. Also the following document "A Guide to The Safe Use of Secondary Lithium Ion Batteries in Notebook-type Personal Computers", which was created by the JEITA, Japan Electronics and Information Technology Industries Association may be of interest http://www.jeita.or.jp/english/topics/ Sharing this information is in all our best interests as it makes our products safer and I am willing to bet we all have lithium ion battery products in our homes so any other info anyone has they can share is appreciated.... regards, John Tyra Manager Product Safety Bose Corporation The Mountain, MS-450 Framingham, MA 01701-9168 Phone: 508-766-1502 Fax: 508-766-1145 From: emc-p...@ieee.org [mailto:emc-p...@ieee.org] On Behalf Of lauren_cr...@amat.com Sent: Monday, February 25, 2008 10:27 AM To: Gartman, Richard Cc: emc-p...@ieee.org Subject: Re: assistance - Lithium-ion custom batteries I have no direct experience with batteries, but I have seen a couple presentations on why LI batteries go bad. The culprit is often minor contamination and errors in assembly. I would recommend insisting on severe QC at the manufacturer. Occasional unannounced factory inspections. Extremely tight control on their supply chain. Preferentially a manufacturer that has a long history of supplying other majors that have been bitten by the battery bug like Sony, Dell or IBM. The Austin area IEEE PSTS has had presentations on this topic from Dell. Perhaps contacting the current area pres. would yield good advice. If your selected manufacturer can't give you a 30 minute lecture on the regulatory compliance requirements world wide for their product I would see that as a yellow flag they may not be ready to step up to those requirements if you hand them down.
