I arrived at the Cheyenne Supercharger today just as a couple of other Model S were leaving; they did not report any problems I have an early Sig 85 with the A pack, and arrived with 18 miles Rated range remaining. On plugging in (stall 2B; all the others were empty) I watched the charge ramp up to 86 kW (251A @ 344VDC) and then in very short order (at about 23 Rated miles) it dropped back to 60-61kW and stayed there until it hit about 100 Rated miles, then dropped slowly to 58kW and stayed there until I unplugged and drove off with 171 Rated miles. Late in the charge another Model S arrived (VIN 30nnn) with 25 Rated miles and plugged into 1B: his charge rate ramped up to 120kW, as expected. Since this was the first time I've arrived at a Supercharger with such a low SOC, I don't really know what to make of this. I've seen 90kW at a Supercharger before, though, so my car is (or was) capable of 90kW Supercharging. Does anyone know if this is necessarily a Supercharger issue, or could the car's battery management software be limiting my charge rate for unknown reasons? I did notice that the car would not allow me to turn on the climate control early in the charge (the app said climate control was disabled at such a low SOC).
