Products tested to the CB Scheme will need to have batteries tested to IEC 62133 after June 27, 2011. However, there are still the U.S. National Differences requiring testing to the UL standards. You will need to test to both for a world-wide product after the transition date. Please note that this deadline has been pushed back. SC21A was supposed to solicit requirements from end product users through the various national committees, and SC21A was to perform a gap analysis between the UL, IEEE, ANSI/NEMA and UN standards for batteries to ensure a "best of breed" approach. SC21A hasn't made enough progress yet to allow the transition without causing a lot of headaches for manufacturers of products using the batteries. I wouldn't be surprised if the transition date gets pushed back again next year.

UL1642 -> professional device; a battery pack does not have a protective device; Li only. UL2054 -> consumer device; any battery chemistry; requires UL1642 for Li battery/pack. There is a new standard in-work: UL2271 - intended for batteries, battery packs, and vehicle charge systems. The IEC has formally recommended the use of IEC62133 in lieu of UL1642, and the CTL has commented on this in DSH616A. And transition dates and requirements are here <http://www.ul.co /global/eng/pages/offerings/industries/hightech/batterie s/iec62133/> But more important, some the IEC tests are more fun than the UL tests...

Here is what I use: IEC 62133 is the standard used for batteries in portable consumer electronics. IEC 62133 is a standard used worldwide except in USA. In USA, UL 1642 and UL 2054 are the equivalent standards UL 1642 is for ONLY the CELL and UL 2054 is used for the complete battery pack. Hope this helps. Ron Baugh From: [email protected] [mailto:[email protected]] On Behalf Of McInturff, Gary Sent: Wednesday, May 26, 2010 1:07 PM To: [email protected] Subject: Lithium Ion Batteries Is there a Harmonized standard for Lithium batteries in the EU. For UL and the US Battery Cells would fall under UL 1642-Lithium Batteries. If there will also be a Battery Pack involved that it would also be UL 2054. Of Course now I'm confused what is the difference between a Lithium Battery and a battery Pack. I'm missing the obvious I suppose but I understand there might be requirements on the cell - but isn't a pack nothing more than a series of cells? Do battery packs incorporate safety circuits - I would presume that whether one or more battery I would have to design a circuit that safely charges, discharges, protects against over voltage, and maybe a temperature monitoring circuit etc - but again I would presume if I do that for one cell I can scale for cells that have been shrink wrapped into a pack.
