I'm getting close to 8m/kwh on the high-end. Realistically, I'm ranging between 3.6 to 5 m/kwh. But when I drove for Uber, I did 200 miles using only 34.1 kwh, I drove slow, and it was mostly city driving. So I could only need 137 kwh for 800 miles. Still prohibitively unrealistic to charge in 10 minutes. It's about 1.4 MWatts to charge from empty for 10 minutes.

the charge power needed for the 200KWH is not 1.2 MWatts for 10 minutes, it's 2MWatts. Mostly because you can only charge fast at lower percentage.
