I cannot find anybody with a video of an EV car working in sub-zero. I see people lying about the temperature and some snowy pictures, but when I see that they aren't wearing gloves or a hat, and cannot see their breath I know they are lying about the ambient temperature.
I did find this article which basically says, I'll die of exposure in an EV in northern MN.
"one Model S owner recommends buying heated jackets and gloves designed for wearing on motorcycles. Dahn says the solution is 'snowmobile suits.'"

The link above does point out that the Nissan Leaf uses battery power to warm the battery which reduced its range by at least half (they tested in a warmer area than where I'm at) while Tesla uses heat from the electric motor to try and warm the batteries. However, nobody says anything about the energy cost in maintaining warmer temperatures inside the cars.
I also found one data-driven site which shows snowy ice roads in and of themselves greatly reduce EV range.
Tesla Battery Range in Sub-Zero and Snowy Conditions
Anyway, for reference: Where I'm at we're frequently the coldest place in North America.

On this morning I had to go to Sibera to find colder weather.

I did find Tesla ad copy where they did testing on a frozen lake in northern Minnesota but they say nothing of the data they collected from northern Minnesota.
Here is a Volt cold weather start and run
you can see his breath once in the car and display says -12
-12 and wind chill of -26 on his phone and is wearing gloves with the special texture to be able to activate the cars touch screen,
also the camera's footage is very dark which does seem to happen in really cold environments some times
as stated- the car does start and run for the first few minutes in vid and ends up on battery 9.1 miles electric and 4.4 on the engine, still managed over 45 mpg.
Looks like Minneapolis? from his Nav screen
