It's extremely linear, modulo speed. It is possible to project your arrival state of charge within 1-2% even for a destination two hours away across significant topography.
- jjav 4y ago> It's extremely linear, modulo speed. On flat land. Throw in hills and the number of projected range miles used by every real mile goes up very quickly. I don't remember the specific numbers anymore, but we had two Fiat 500e cars and commuting over a mountain drained a lot of projected miles even though the climb was just a few miles.
- martijnvds 4y agoYou regain a bunch of miles on the way down though, through gravity and regenerative braking.
- jjav 4y agoUnfortunately, very little. I went back to look for my notes on this and this is what I experienced: The Fiat would use up about 30-40 miles of indicated range to go uphill less than 10 miles. But it would only regenerate 2-3 miles (of indicated range) on the downhill side.
- djaychela 4y agoNot my experience in my Zoe. You get nearly all of it back on the long climb and then descent which I often used to do before I moved.

- stickfigure 4y agoThe Leaf is somewhat famous for having poor battery management; it's one reason we avoided them. I don't think a used Leaf could handle a 50mi roundtrip commute, especially with a 10yo battery. The Fiat does have a range penalty for cold weather (it occasionally gets below freezing in the part of California I live in) and running the heater (one way; usually it's warm enough by the trip home). My wife still gets home with > 10%. Keep in mind this is a 10yo car with an 80mi range; newer cars have bigger batteries.
- sundvor 4y agoKudos on making it work for you! It's a great example you don't have to have the latest and greatest to drive electric.
- stickfigure 4y agoCommutes are extremely predictable, it's the same every day.
- logifail 4y ago> Commutes are extremely predictable, it's the same every day. Tell that to my colleague, who due to an accident near a major junction, took over an hour to travel a key couple of miles on his commute home from work yesterday. Some journeys are "predictably unpredictable" during rush hour.
- Kirby64 4y agoWell, the good news about an EV is that if you're creeping along at barely any speed, the consumption is going to be way lower than a comparable gas car. Basically all you're using is AC/heat. A gas car comparably is much less efficient while idling.
