The cells are charged serially? I thought early on i read that the cells are charged, voltage and temp monitored, individually. i.e. in parallel.
Have a bunch of closely stacked cells being fast charged and discharged in series seems like it would be a really bad design. If for no other reason than hot or cold soaking overnight, then cranking the APU, then fast charging it again, would cause huge temperature variations from the center of the battery to the outside cells, unless there was active cooling, which there is not.
Just asking. Are the cells charged and monitored serially or in parallel?
@USMCProbe
Have a look to the pictures.
You will clearly see that the cells are put in serial. The thin wires at the joints come from the BMS which BALANCE charging current and monitor each cell.
So charged in serial, but adjusted individually.

To put the BMS in the same case beside the cells, is not a good idea IMHO...
