I grew up and rode the bus to school in Iowa. There were multiple days in my youth that local schools were closed because the diesel busses wouldn't turn over. The guy that maintained ours used Amsoil, so our buses worked, but cold weather doesn't only hurt electric vehicles.
There were reports over this past week over people having difficulties charging their electric vehicles due to the cold temps (-30°F wind chill and worse). All of the schools in the state were closed as well as many businesses.
Basically, it's a self correcting issue. If it's too cold to charge a battery, it's too cold to have school.
I rode the bus in Alaska. The buses ran well below -50f. It turns out that it's not that hard to keep your batteries and oilpans heated if you bother putting plug-in heaters (literally, electric blankets for the purpose) in your fleet vehicles, winterize your vehicles, and plug them in when it's cold.
I get that it's uncommon to be that cold-prepared in places that don't expect to see temperatures below -20 for more than a few days in a given calendar year- at some point, it makes sense to just call it off when it's that cold. After all, do all (or even most of) the kids have proper clothes to deal with real cold?
Really cold weather can be adapted to, it's just that when you don't need it that often it makes sense not to spend the resources doing it.
For sure. The ROI really isn't there when it happens every couple of years. Like you said, they do call it off when it's that cold. It's not safe for kids that have to walk to the bus or school. The main thing is that electric is the same way, so it's a moot point.
No, the larger point is that it's a struggle to make diesel work at +20F if you don't do the things to make it work, and yet these things can be made to work reliably at -50F. The obstacle isn't the limitations of the technology, it's whether or not the cost curve makes sense. Electric can be made to work cheaply, if it's important to you that it work- just like it's possible to make that diesel turn over at -50F
When I say electric is the same way, I mean that if it's too cold to run the vehicle, it's too cold to have school.
Ok, that's fair. The point I wanted to make upthread was that these sorts of impossible things are regularly made to work when making it work is worthwhile. Most of the 'but this is a limitation of the technology' talk here (about how EVs can't work in the cold, etc) is defeatist bullshit that ignores that really if you want it to work it can be made to work
