That won't do much good if the car isn't moving. I see I need to make another phone call,
Car (motor) doesn’t have to move to put a “holding” current through it. I suspect they could put plenty. Looks like it can generate at least 3000 watts.

Just got a message saying battery is heating. Power will improve as you drive.

(Looks like a small battery with a red snowflake in the middle of it.)

Observations in Ottawa this morning after last night's low of -23ºC
Conditions
- Both cars left unplugged overnight (simply forgot to plug one in)
- No garage or carport, just snow-covered driveway
- EVSE (Flo Home G5, J1772 plug only, mounted on outside wall) is shared 'cause Leaf came first
Observations
- 30kWh Leaf, left overnight at ~95% SoC, sent txt msg stating battery heater was turned on at ~6am
- msg indicated that I should plug in the car
- current SoC (2pm) is 86% and Leaf is still not plugged in
- LR M3, left overnight ~42% SoC, no messages at all
- checked phone app at ~10am and battery showed 37% SoC (+ snowflake symbol)
- set interior to 26ºC for 25 mins (minimize chance of frozen charge port, door handles, etc)
- didn't notice anything worse than normal winter stuff (frozen door handles)
- after entering car, noticed dots on both sides of power meter line (no regen at all & battery power at ~50%)
- car drove as normal (have to back out and reverse car into driveway in order to reach EVSE cord)
- charge port opened without any incident/noise/messages, charging set to 90% at 30A (7 kW) using J1772+adapter
EVSE cord was very stiff (expected). Carefully didn't force the cord to do anything other than minimum twist/turn required to get the plug+adapter into Tesla port.
Just sharing that car charging outside in dead of winter is ok (so far). Weather forecast is for 3 consecutive days of bitter cold so will report back at the end with more info.
Also did you check the rated km left? With snowflake icon the percentage and rated km don't always line up. That is you'd expect 76% to be 379km normally but it was probably less km.76% battery (snowflake icon) on app
I didn't check the km (but will later today).Also did you check the rated km left? With snowflake icon the percentage and rated km don't always line up. That is you'd expect 76% to be 379km normally but it was probably less km.

I may be wrong, but my understanding is that the battery percentage displayed on the screen & app is actual. As in there's 76% charge left in the battery.
How many kms/miles you/I can get from that 76% may depend on quite a few factors. Therefore, as a metric, I was trying to get something that would apply more universally rather than the kms that I could get out of that 76% given the road conditions, rims, tires, tire inflation, air temperature/density, cabin temperature, seat heater(s), battery temperature, driving habits, etc.
I realize that the bottom line is how far can one go on that 76% and I'm not taking anything away from the validity of that goal. But my 300kms may not be your 300kms.
My hope is that my observed 76% would be close to anyone's 76% given same starting SoC + chilling temps + duration.

I have not seen that message yet. Thanks for showing us. Now all we need is an actual battery temperature reading somewhere....Just got a message saying battery is heating. Power will improve as you drive.

It should start heating when it’s that cold and plugged in. You can also check the app while driving and view the climate control screen.
