Second, do you have an opinion or data on what minimum cell voltage is reached at VLB in these post-update packs ?
I managed to get a brief chat with the specialist and a test was done at 1C which did create a significant rise in temperature. I would expect slightly less capacity but didn’t get any data. By staying down at C/3, which is also a reference used by AESC, the temperature rise was only a few degrees and removes that as a variable.
Cell voltages were usually not taken down very low to turtle as the amount of energy on that last slope (e..g once under 2.9V per cell) is very little. These cars are owned by others and don’t want to stress the battery.
