I'm an EV newbie and this is my first winter with an EV-- well, as "winter" as Phoenix gets. Mornings have been in the 30s or 40s, and afternoons in the 50s to 70s. My driving efficiency since I got the car is about 4.4mi/kWh. I was seeing closer to 4.8 during the milder temps in October and November. But as December hit, it's been more like 4.2, even when I can get away without running the cabin heat (which is most of the time). During December, I had been L2 charging my car right after getting home, when the temperatures were most moderate.
This morning, I tried something different-- I charged for 45 minutes before leaving home in the morning. My efficiency driving to work was a number I hadn't seen in a while: 5.1.
I hadn't really intended the different charging routine as an experiment, but now I wonder if charging right before driving in the 40s temperature warmed the battery enough to make it significantly more efficient. Have you observed the same?
