So, had to make an early morning 21 mile jaunt, with temps in the 20s. Roughly 25% local, 75% highway. What better way to experiment and understand the impact of the cold on my range?
In warm weather, my GOM has shown as high as 282. In highway driving at ~73 in September, from Michigan to Florida and then Michigan to Massachusetts, we settled in pretty much at about 2.9 miles per kWh efficiency. Trip 1 would show as high as 3.1.
I set out with 179 miles of range, at 90% charge, with the car preconditioned (no heat, no seat). Temp of 23 degrees. I ran the heat, set on 68 degrees, and briefly had the seat and steering wheel heaters on. My 20.4 miles of driving, on Trip 1, came in at 2.3 mi/kWh with 15% climate use, and 6% blamed on external temperature. Battery was at 78% and 151 miles, so I used roughly 12% (roughly due to rounding and the fact that I was at 88% on my driveway). Calculating - .12 x 88 = 10.6kW, 20.4 miles = 1.93 mi/kw vs. Trip 1 saying 2.3. Used 28 miles of range to go 20.4 miles.
I was in the store for 15 minutes, so I didn't remote start. On the way home, I only used the heated seats (turned on the passenger one also), and the steering wheel, I did not turn on the car heater.
When I parked, I was at 151 miles of range. When I came back in 15 minutes, I was at 149, but still 78% charge. Temp was 24, so basically the same. When I got home, I had used 8% of battery (at 70%), and range was down 18 miles after driving 20.4. Trip 1 showed 2.7 mi/kWh, 17.4% better than the way up, which ran the heater. Showed 0% from climate use, and the 5% (vs. 6%) from temperature. Car displayed a warning when I arrived home, "Outside Air Temperature Low Plug Vehicle In When not in use." For the grammatically correct, the words in, not, in, and use were not capitalized for some reason...
So, it appears that I can drive, at speed on the highway, in cold weather, and lose 10 - 15% as compared to my September driving. Instead of planning my routes at 2.6 mi/kWh to be conservative (and getting 2.9 or higher), I will plan on 2.2 and hope to get 2.6, which would be closer to 20% down.
At 88kW, and using 70% between charging stations (80% of battery, going down to 10% at the most), that's 136 miles of range, maybe as much as 160. If I'm driving 600 miles in a day, that's 4 charging stops leaving the house with 100% and charging at a hotel. One more than in the warmer weather.
However, it doesn't bode well for trips. While I can do the math and figure out leaving the house at 100% and headed south, and making it to the first EA chargers, I can't make it home from them at only 80%. I'd have to detour and get on the Ohio State Turnpike, driving 40 miles out of my way, to hit another EA charger, and I'd be at 152 miles with a range of 160.
Looking more and more like taking the ICE F-150 with 700+ mile range is more likely.
