I'll add another cool weather range data point from yesterday:
Trip: Grand Junction to Montrose, Colorado
Distance: 70 miles
Elevation gain: About 1100 feet net
Altitude: About 4700 feet to start and about 5800 feet at end.
Temperature: 33 degrees to start, 29 degrees at end
Battery temp: Four bars to start, five bars at end
Charge: 100%, in garage ~45 degrees, so not especially cold; left soon after charging finished
Speed: More than half the route at 55 mph, but no higher despite the 65 speed limit
Tires: 38 psi cold at start
Road: clean and dry
Heat: Ten to fifteen minutes (in Eco mode) when I realized I was going to make it but mostly off except for heated steering wheel.
Drive setting: entirely in Eco, much of the highway stuff on cruise control except for hills, I did coast down two grades in neutral.
Trees: I "made" about 2 and a half trees so I was trying to be careful.
Results: I got the "low battery" warning about one mile from my destination, so I had perhaps ten more miles left. So, 80+ miles range at freezing temperatures but also at moderately high altitude (less dense air).
Edit: Since I didn't record miles/kWh I believe I can calculate it from the recharge:
Assumptions: 75% efficiency from wall @ 120V, 4 Watts idle on EVSE, about 12 hours idling.
((22.82 kWh - (4 W x 12 hours)) x .75)/70 miles = 17.079 kWh/70 miles = 0.244 kWh/mile = 4.1 kWh/mile
That's the best I can come up with.
