Piles of Tesla owners stranded at charge stations abandons their EV's.

I experimented the other day with the heating in my car.  I tried 'off' and '20C' and the difference was 48 miles range vs 45 miles range, when the battery was at a low state of charge.

I drove home 33 miles with the heating on and arrived home with 8 miles of range, which perfectly matched the so-called "guess-o-meter" (I generally find the indicated on the car to be accurate, usually slightly pessimistic).

This is one issue with Tesla's marketing.  They make exaggerated claims about the range capability of their cars, and the in-car display tends to be overly optimistic.  I would want the range meter in any car to be generally pessimistic.  Tools like ABRP can take into account the actual range of the car (regardless of the display).

1 year ago this happened!



and 1 year later, same dude at same company charging station:

Or maybe people who have a different concept of "winter".  If you have a heat pump system (not everyone does) then -5C is fine.  But -5C isn't what the temperature was where the situtation happened as mentioned in the title of this thread.

Yes. People living in Alaska, Siberia, or maybe Northern Finland, are unlikely to buy EVs anyway: not only temperatures can go down to -35degC regularly, and -50degC peak cold, distances are long so a "short trip to neighbor's for a coffee" might be 300km one way, without civilization in-between. People want to be self-sustained so they will have their own tanks of gasoline/diesel, maybe thousand of liters/gallons, and some old-ish car they know inside out and can service on the road. Number of such people is also counted in thousands, not millions, so totally irrelevant in the big picture. EVs are clearly not for them.

This leaves EV use in a bit more inhabited areas: say Southern Canada, obviously USA as whole, Southern / up to mid Finland for example. And that would limit the temperatures to usually down to -25degC or so, and maybe -35degC absolute peak. And this is within the realm of possibilities for current EVs, as long as you plan ahead a bit and know the limitations.

Of course, having to plan ahead sucks; limitations sucks. On the other hand, if you have to endure with some limitations for a week or two every 2-3 years, maybe it's not too bad. Nearly all so-called "failures" are not actually total technical failures, car stopping midway, just car losing 10-20% more range than in cold yet bit less extreme weather these same drivers have experienced before. I mean, if you have already driven in -15degC and noticed your range dropped by 30%, then maybe it's a stupid idea to assume it's not going down much further at -30degC, and to assume every charging station in existence is always operational.

But there have always been people who get stranded even with a gasoline car because they are out of fuel. Even such trivially simple planning with huge safety margins (like, the range is 800km, stations available every 50km) is too difficult for some.

begin with a 1000 meter drilled bore, a oil well, a oil tanker, a refinery, a gasoline delivery truck, a gasoline station, finally the red can. Typical distance traveled (excluding the highly windy refinery plumbing) is at least 2000 miles. the production montage would have the world map with the red dashed line arrows on it  ;D. Or a disturbingly long time lapse of the ship traveling across the god damn ocean. Maybe it even get attacked by houthi pirates.

the tree burning generator is a highly optimized solution. Like damn when you build it you can even recharge the battery operated chain saws with it. practically a von numan machine. Where is that from, pandora?

Luckily for us the science of economics can easily and accurately measure the cost of an extended supply chain for the end user with a single number.  There is no need to guess.

Well, except for politicians putting their thumbs on the scale for their favored industries.  It is part of their nature to ignore economics.
