This data is mostly known by now, but results vary by battery temperature and individual Supercharger so here is Albuquerque, NM at 8 am, after a 13 mile drive. I arrived with 76 rated miles and left with 248-ish. I had two main questions in mind: kW at any particular SoC, and average charge rate for a 20% - 80% charge session. The latter charge interval is of more than passing interest since it approximates ideal Supercharger hopping for this car presuming the charging intervals are about 180 miles.
Method:
I grabbed smartphone captures periodically
Data dumped into Google Sheets
Summary:
114 kW from < 40% SoC
Approximately linear drop in kW from 40% SoC down to 50 kW at 80% SoC
The graph approximates a trapezoid, giving an easy way to estimate average kW for this SoC charge interval:
(2*114 + 4*0.5 * (114+50)) / 6 = 92.6 kW
(5 photos are missing. I'll add them when the system is more cooperative)
