Moshe,
The standards you listed there are correct for cell and pack Recognition by UL; I’d budget at least 4, or even 6 months, if you submit directly to UL. #1 – You can submit direct to UL, all battery testing goes through their home office in Illinois, USA. Or you can probably have your pack assembler submit it for you since they probably do it more often and have the contacts already. Our assembler uses an approved outside lab (some branch of Motorola?) to do all the testing and UL either accepts or witnesses the testing/data and this saves time on the approval of the pack. We’ve had to submit cells for UL 1642 approval directly to UL. Contact me off-line if you want more info on our pack assembler. #2 – Your best bet is to, at some risk, submit the cells and pack in parallel test programs, otherwise you are looking at 6-9 months for serial testing. Actually, the better plan is to specify a cell that is already a UL Recognized Component (R/C) as that will cut out the cell approval (time and cost) and help with the pack approval, too, if you absolutely need a custom pack. If possible, buy a pack that already has the 1642 and 2054 approvals and be done with it! #3 – U.S. Dept of Transportation requirements for Lithium ion cells: http://edocket.access.gpo.gov/2009/E9-20343.htm which seems to be following the UN labeling and testing standards for international transport. Your pack assembler should have more information on this, too.

We are contemplating to introduce a battery-embedded solution, which is naturally equipped with our receiver technology. Battery manufacturers tell us that we need UL 1642 (for the cell) and UL 2054 (for the battery package) and that these certifications lasts ~3 months. Question #1 - UL test house that performs battery approvals. Question #2 – what is the fastest possible way in which we can obtain each of these certifications? Question #3 – is there any other certification that we might be needing? Thanks - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
