Tesla need to update their charging curve, its should not take 40 min on a V3 to Charge to 90%
But it does take 40 minutes. Even though the superchargers are capable of outputting 250 kW, the battery pack is not capable of accepting that much power at higher states of charge.
If you want to go 10% to 60%, you’ll find that it takes fewer than 15 minutes with a properly conditioned battery.
