Your 20% variation number seems valid for my EV.
I have a 2022 Nissan Leaf with 220 miles EPA range. I've found that this number is reasonably close to correct if one is driving under 60mph on country roads under moderate climate conditions. We live in Ohio and so I have actually done long drives like that to go to remote places to go camping. (There are, surprisingly, both L2 and fast chargers around in rural Ohio but you definitely need an app and need to check ahead of time.)
Speed matters because air resistance increases exponentially with speed, not linearly. Driving 60+, lots of stop and go, or using HVAC a lot will bring it down the range to as low as 180, but that seems like the worst range I've seen. That was driving ~75mph with HVAC on.
- amluto 3y ago> Speed matters because air resistance increases exponentially with speed No, drag is somewhere between linear and quadratic as a function of speed, not exponential. (Although it gets weird around the speed of doing.) Heuristically, if you’re pushing through a cloud of particles, the number of particles you hit per unit time is linear with speed, and the impulse per particle is also linear with speed (because it’s the difference between your velocity and the particle’s initial velocity, times the particle’s mass, times a constant that’s around two for an elastic collision).
