And, it's not just Chicago. SC sites all around the region show multiple stalls down. There's clearly a cold weather problem that needs to be addressed.my guess is poor trip planning to even get to single digit % SOC and then long lines, broken stalls and LFP batteries which ain't the best for super cold charging
yeah. for sure. if the stalls fail or ice over when it's extremely cold... that's no good. I'm just surprised that this is showing up just now when in Norway - with a ton of Tesla's - it gets colder and colder for longer.... yet we dont see a lot of complaints from there (?)And, it's not just Chicago.

yeah... reading through reddit... a lot of the Chicago folks went with single digit % SoC to charge in -12F weather. Sorry - that's just stupid. All it takes is a long line and some broken stalls and your car won't be able to precondition or run out of juice by the time you find a stall.Norwegians just use common sense. (Bjorn Nyland excluded )
Like, do not get out in extremely cold weather.
And if you do, do not run down your battery to almost 0% SOC, preferably not below 20% SOC.
Maybe Scandinavian SCs have weather-related design differences from the failing SCs in Chicago.yeah. for sure. if the stalls fail or ice over when it's extremely cold... that's no good.

Why can't the car precondition if it's plugged in to the supercharger?
At that point, it’s no longer pre-conditioning, just conditioning.Why can't the car precondition if it's plugged in to the supercharger?
It can. But it can take up to an hour of being plugged in to a Supercharger heating a cold soaked battery before it actually starts charging the battery. It may be that people think it is broken at that point and give up, never giving enough time to heat the battery.What I mean is, why can't it charge when it's too cold? I get that the battery needs to be heated up first. But why can't that happen while the car is connected to the supercharger? The fact that cars are being abandoned indicates that despite being plugged in, the car can't be heated up and charged.
yeah... under 0F heat pumps become horribly inefficient and at the minus 10F in Chicago I doubt they work at all or enough to heat the battery pack.Okay I watched the video. To summarize, the heat pumps don't work very well when it's cold outside. So if the car is cold, it's not going to be able to heat up, even if plugged into a supercharger.
Based on that, it doesn't even matter what the state of charge is. You could be at 50% battery, but if you deep freeze the car cold enough, then it wouldn't be able to heat up enough to charge or move, even if it is plugged into a supercharger or AC power.
Step one is for Tesla to determine the cause of so many SC failures. Remember that, according to the Tesla app, three SC sites were completely down and most other sites had multiple stalls inoperative. Once the cause of the failures is found, then effective solutions can be determined.I've also read that a pack of Uber/Lyft drivers had converged on the SC before dawn. They were basically hogging the working stalls. I think the best solutions for the future are:
1 - build canopies where possible
2 - more SC locations (needed regardless)
3 - educate new owners in these northern climates on winter best practices.
