There are lots of small cylindrical cells in a Tesla battery module, sort of like big AA batteries.
That example doesn't add up - 6S 86P is 516 cells and are the modules in the P100D, 444 cells was a previous architecture of 6S 74P used in the lower capacity 85 Tesla model S.Can anyone explain the meaning of the "6S 86P" battery module in a tesla? I understand that it means 6 in series and 86 in parallel connections. From what I know, a module consists of maybe 444 individual cells. How does that add up?
Other way around; 96S 2P. Or we would only have an 8V battery! Pouch cells can be cooled more easily as they have an easier surface area to work with (a rectangle, rather than weaving through a load of cylindrical cells), just that Nissan decided it wasn't worth the effort I guess. Mechanically, both have pros and cons. There are far more connections with cylindrical, and one failing can reduce the capacity of the battery. In Tesla's example, having such a large amount in parallel helps as you would only lose 1/86th of the capacity.Those of us mere LEAF owners are just 2S 96P for the whole car - 192 pouches - much simpler but harder to cool and maintain mechanical integrity for.
