I am probably considered a very stubborn man, so be it.........
As the battery is definitely the same, and as the BMS (LBC and LBC2) are embedded in the battery pack, I doubt they are programmed differently.
What we've noticed is that when the charger reports 43 kW, the care is tricked into believing it is hooked to a 22 kW charger, no more, no less, see http://canze.fisch.lu/charging-the-r240/
So a difference in the BCB programming (complete new hardware anyway) is far more likely.
Temperature effects are VERY steep indeed, so it is not very useful to compare with "roughy the same" temperatures. 1 degree can make a whopping 2 kW difference in max charging power. I can't remember if I have posted the approximation sheet here, so pardon me if this is a double post:https://docs.google.com/spreadsheets/d/ ... sp=sharing
