Question, not argument: what is the definition of "super cold?" Asking because in my area, which is not an area associated with bitter cold, we have been in sub-20F temperatures for a week, and overnights are down to sub-10F. My PHEV has not done well in this.

This area sees these temperatures for a total of, I'd guess, 3 weeks (non-contiguous) annually. There's usually a couple days of around 0F each year (and if it goes lower than that, it sticks around for several days). Some years, we get 4-6 weeks of such cold. Basically everywhere from Pennsylvania, Ohio, New York, and north of New York will see the same or worse.

Sorry for the long explanation. I want to calibrate on what "very cold" means to an EV.

The latest Tesla heat pumps can extract heat from the air to heat the battery and cabin down to -10C. Past that, they have to use resistive heating which is much less efficient. I would say that’s where the “cold” line begins, and of course the colder it is the more battery you have to waste. Last weekend I took a 3 hour round trip (starting with 90% charge) in -30C and had to charge only for 5 minutes to complete the trip.
Thank you for the reply!
