I'm pleased to hear that at least Tesla does not consume battery energy to heat the battery. I have read on a Bolt EV forum that the battery will be used to keep the battery temperature at around 0C or until the SOC falls to 40%. I dunno, there are so many contradictory claims floating about...

Thank you for that - it is as described. The channel owner has also replied to my query in the comments and is ready to take some power consumption measurements for his new Mach E when it gets cold again (forecast is for warming up next week and +17C next Saturday however).

Yes, it looks like -25 would indeed be a problem for 120V charging and also a significant power consumption issue for 240V charging.

Yeah, 2 to 3 KW is the range I'm seeing from other sources but, that doesn't give the cumulative energy consumption as the heater on/off cycle time has to be considered. If it's v cold for example and the heater is on 1/2 the time, the daily consumption would be 36 KWh per day (assuming a 3 KW...

Hey thanks, excellent info, even though it appears to seriously contradict Tesla's documentation. I'm beginning to understand why there is so much contradictory information on the topic of cold weather battery maintenance, on other manufacturer forums as well as this. And, the guy lives in...

Have read this thread with a lot of interest as I live in winter frigid Alberta and am contemplating purchase of a MY. I do wish Tesla would publish some definitive information on the topic of cold weather charging and heating as there appears to be a lot of contradictory evidence and opinions...

Yes, a closed garage will help a lot because, as you say, no wind chill and, the concrete floor holds a lot of residual heat that will help to reduce temperature drop at least for a day or two. Any sun shining on the garage would also help.

OK, thanks for that. If the car/battery had cooled to ambient temperature though (say -20 or -30) and it was then plugged in I suppose the charge current would first be directed to heating the battery to at least the minimum charging temperature before battery charging commenced (IIRC lithium...

Hello all, first post. Was wondering if anyone has measured power consumption when plugged in during periods of cold weather. As I understand it, the BMS will draw power to keep the battery above a certain temperature, that power either coming from the charger or from the battery itself. If...
