Is that a real-world efficiency number? I've been driving electric since 2012 and my average is around 4.4 - 4.5 miles/kWh. I don't use the heater much, so that may explain the difference.
Your 4.45 miles/kWH is 0.22 kWH/mile, so you're doing mostly non-highway, little heater use, yes.
Yes, 0.30 kWH/mile is exactly the 2020 Nissan Leaf SV figure from running the EPA's
mixed City & Highway style driving.
If you're on the highway a lot, and/or use the heater, your efficiency will be worse.
City driving cycles, low-speed stuff, less aero drag to fight, results in better efficiency.
It all depends on your specific driving cycle. If estimating costs, it's best to assume
mixed City/Highway driving, not purely one or the other only.
Slow steady speeds, and you'll get 0.2 kWH/mile as "Real World" for that driver.
Fast driving means 0.4 kWH/mile as "Real World".
Real World is a bell curve, and we want to use the average.
That's an
average 0.3 kWH/mile, the correct one to use in notional calculations.
