Came in here to ask about this exact issue. Is anyone else having this problem?
Let's hope it can be fixed via software update.
Any thoughts on intermittently or periodically turning on the heat so as to turn on the battery heater to prevent cold soak?
I was wondering about using Stats app and scheduling to run the heater every few hours to keep the battery warm when it gets below 0°
Anyone do something like this?
I know you posted this awhile back, but this is exactly the type of real world winter efficiency data I am looking for. I live in similar climate in Massachusetts. In general what is your efficiency in the winter? I haven't bough a M3 yet and considering a few other cars still.View attachment 638295 Last Thursday we drove about 100 miles in 18F temperature in our 2021 SR+ with winter tires. 80% highway and interstate. I will be happy if my consumption is 231 Wh/Mile in the summer.
Hoping this is the appropriate thread to post this: electrician coming tomorrow to install a 14-50 outlet. There wasn’t really any flexibility in the filled-up little breaker box in my garage, but I did note that there was a 50 amp breaker in the box dedicated to the air conditioner, which I haven’t used for about 15 years. So the electrician will be wiring into that breaker to obtain the voltage needed for the 14-50 outlet, on a shared basis with the unused air conditioner. The electrician is a reputable guy who has been working in my neighborhood for almost 50 years, so I’m assuming he wouldn’t set up anything that was potentially dangerous or that might cause future electrical problems, but I thought I might lay out this scenario on this thread to see if anybody here sees any big problem with this strategy…
Note: moderator placed my post in this thread after it was originally placed in the thread “Definitive 14-50 NEMA Outlet Guide”. Not sure why it would be moved to the “Winter charging issues, frozen charge ports, road trips” thread… I probably should be pleased that it wasn’t simply deleted.
Not a big deal, outlet all installed already, working well and nothing from the breaker to the plug into the car seems to even get very warm, after 6 hours of charging…Hmm.. we have more than one moderator for the model 3 subforum, but I dont remember moving your post from the 14-50 thread. I havent looked at that thread for a while actually. I could move it back but its been answered here already.
Well, keep in mind that these are two very different kinds of scenarios that will have different levels of energy usage. First drive of the day, when the car is cold, for a short distance, like 10 or 20 miles is going to have some insane, atrocious energy consumption figures, and yes, that doesn't surprise me it's going to show about 2X the rated miles consumed versus distance miles. But for long traveling trip drives, this consumption rate will drop off quite a lot, since the car finally gets up to a warmer temperature, both in the cabin and the battery/motor, and it can slow down to cycling the heating on and off some, instead of going full blast for a 10 mile drive. So the long trips won't be so dire for range concerns.maybe put about 10-12 miles on the car but my range miles went from 96 down to 73 so about 23 range miles.

This is all to say the range and usage is only an issue if I ever decide to drive up to Buffalo in the winter, and that just isn't going to happen!
Like I said in the first post, it wasn't unexpected that it was so bad. I took it to the SC today because I can't charge it overnight at home for the moment, and you should see the numbers that the battery conditioning/warming produced on the way there. I can't charge overnight because the outlet I was using got a little crispy and that got me nervous. I switched outlets but the cord has to go out an open window, and the temps have been too damn cold for that. I have the inspectors coming in 2 days for my solar install and then I'll be good.Well, keep in mind that these are two very different kinds of scenarios that will have different levels of energy usage.

But after the charge I was driving around Brooklyn on the streets and everything was normal. Temps had risen to about 40 degrees and the car didn't mind that at all. I was getting usage below average just puttering around.
This is part of my theory (indirectly) about why they moved away from the "cards" which continually displayed your consumption and made it slightly more difficult to see your car's consumption. They are trying to move people away from constantly obsessing over / focussing on their energy usage. Of course, this makes no sense to me, as especially in the winter, or when on a long trip, being mindful of that info is critical. But just a thought.Like I said in the first post, it wasn't unexpected that it was so bad.

But only slightly more difficult. I've added the consumption graph as one of my customizable icons. I watch it now more than ever.This is part of my theory (indirectly) about why they moved away from the "cards" which continually displayed your consumption and made it slightly more difficult to see your car's consumption.
