So there's been some media stuff about Tesla chargers going down or getting long lines in this extreme cold we're having.

The factors there are complicated and mostly this is impacting people without charging at-home. As it happens, I'm now making a daily commute - just started in fact! And I'd like to report that my car is having no issues at all in this weather, and I haven't even plugged it in to charge in a few days.

This evening I'll make a quick little Connextras video about this, I think. What exactly the issue is with the Tesla chargers is unclear, though I'm seeing reports that charge handles are plugging with ice - which seems reasonable. The worst aspect of Tesla's charger design is how poorly they retain the handle - it falls out easily and can end up face-down in snow. That needs improvement, and perhaps a heated connector makes sense in this climate.

Growing pains are real, but this is mostly FUD*

@[email protected] I mean, it shouldn't be the technology, right? Tell me if I've slept through that part of physics class, but lower temperatures should be better for charging!

@[email protected] Well... for cables, sure. For the battery? Absolutely not. Cold temps wreck battery charging performance which is why most EVs have some means to warm up the cells. Nearly all have had this to keep the battery above some minimum threshold, but newer cars work to heat the battery pack to properly warm temps en-route to a fast charger (called battery preconditioning) which greatly reduces charging time.

@[email protected] oh, yup. I've clearly slept through chemistry class, then! Thanks for explaining :ablobcatheartsqueeze:
