Most don't realize how much wind affects range. A 10mph headwind can easily reduce range from 230 to 200 miles. 10mph is not a lot and obviously very common.

http://insideevs.com/chevrolet-bolt-bea ... -champion/ Interesting that they got 250 miles out of a full battery at a constant 65 mph with no a/c or heat. Very useful information for me. It seems that a/c drops range by approx 10% or so. Still 60-65 mph with a/c works for us. Nice thing about EV's you can slow down and extend the range.

It seems like when you turn the AC on or off, the range estimate decreases/increases by a different amount depending on the state of charge. Usually it is 12% but when the battery is lower, it can be 8%. Also, it always seems to proceed in two stages: first immediately dropping by half of the final amount and then then other half about half a second later, but that could be a UI thing and not a methodological thing.

I find watching the energy consumption for accessories is the best way to make this determination. With summer coming on (with a vengeance) in SoCal, AC on (set to 71°) most of the time, I am seeing about 4-5% of my overall energy consumption going to accessories. So that's maybe a ten mile hit to range. I set the fan to two or three bars. BTW the fan takes some juice too. Try pushing it up with the car stopped, and you'll see your "idle" consumption go from one to two Kw.

The heater is far more energy consumptive, 10-15%, even in our mild winters here.
