Cold Weather Test

We took a trip to Sioux Falls this last weekend. We stayed at a friend's house overnight so the Truck was parked outside without being plugged in. We arrived at 6 PM and we departed the next morning at 8 AM. Outside temperature was 0F and very little wind. During the night the truck used 32 miles of range due to the cold. Next cold test I plan to plug into a simple 120v outlet and see how my range is affected. I see now why the truck tells you to plug in when it is cold outside.

Do you know if it was 'used' by HV battery % loss or just a recalculation of range guessing by the GOM?
Good question I didn't look at the battery percent rating so I used the GOM on the Ford Pass app.

Once you were on the road, how was your range in the cold weather?
The GOM places the range at about 30% less when this cold, which seemed pretty accurate based on miles driven and battery percent indicated. The trip energy meter put us at 1.4mi/kWh vs a normal of 2.1 mi/kWh. Cabin energy used was at 11%, Ext energy was 12% and Acc energy was at 2%. Incidentally I set cruise at the speed limit except in South Dakota. I kept my speed on Interstate 90 at 70 mph vs 80 mph.
It is likely your battery SOC didn't change and what you are seeing is an updated range based on temperature.
I will pay attention on our next trip. I believe the battery % did go down but the amount at this point would be a guess.
