Hi Gary,
The standard that you seek is EN/IEC 62133. It addresses the requirements at the cell and pack level. In general, your explanation of cell verses packs is correct. There are some variations depending on the exact standard you are using but not significant to the grand scheme. UL 1642 is lithium based primary (non-rechargeable) and secondary (rechargeable) cells. Do not worry that UL 1642 references batteries. Only cells are evaluated to it. The following tests apply to UL 1642: Low Pressure (Altitude Simulation) Test, Impact Test, Vibration Test, Short-Circuit Test, Shock Test, Heating Test, Crush Test, Abnormal Charging Test, Forced-Discharge Test, Temperature Cycling Test, Projectile Test UL 2054 on the other hand can include cells that are NOT lithium based (Nickel for example) and batteries of both chemistries. The following tests apply to UL 2054: Low Pressure (Altitude Simulation) Test, Impact Test, Vibration Test, Short-Circuit Test, Shock Test, Heating Test, Crush Test, Abnormal Charging Test, Forced-Discharge Test, Temperature Cycling Test, Projectile Test, Abusive Overcharge, Limited Power Source, 250 N Steady Force, Mold Stress, Drop Impact Some of the UL 2054 tests look kind of familiar to the UL 1642 tests because they are also included in UL 2054 to deal with cells of other chemistries.

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. I;m trying to get the scope for both of these documents but stumbling Gary McInturff Reliability/Compliance Engineer Advanced Input Systems Esterline Corporation 600 West Wilbur Avenue Coeur d' Alene, Idaho 83815 Tel: 208 635 8306 Fax 208 635 8706 - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
