Another thing I hate Tesla for is the fact that their shitty cars poison the well for basically any kind of electrified transport, by way of their greenwashing these bazingamobiles.

Trying to sell the public on electric transport that's actually scaled properly to work, like buses and trains is hard enough without connections to tesla

Lmao. Yet another case of "If this had happened in China it would be deemed a failure of the Chinese system" hours

BUILD TRAINS

Man.

A lot of folks i know in northern climes have a plug in battery heater, they run a power cord from an outlet in the house or whatever, keeps the battery from freezing solid. Figures Tesla wouldn't have something like that.

yet another Tesla owner L

Elon has a plan. He wants to monumentally speed up global warming.

This is what you get when your entire engineering team has never left California or imagined a place that isn't California.

I'm so glad that I'm too broke to waste money on a Tesla.

iirc Norway and Oslo specifically have very high EV adoption rates, so I would chalk this one up to Tesla ecosystem being badly designed

Quite literally why I call people dumbasses to their face if I see them driving teslas up here.

I rented a Polestar recently on a trip to California. I parked it at my in-laws place at 13% battery. The temperature that night was around 40°F, when I got into the car the following morning I was at 9% battery losing 4% over night in mild-cold weather is insane. I have no clue how electric vehicles will run in cold climates.

My boomer relatives have been voicing this criticism of EVs for as long as I can remember, sad day when they are proven right

Lmao, no my dudes, it's pretty well understood that you need to keep the battery warm enough to be able to charge. This is not some fucking unexplored field of science!

Anybody who owns a phone knows that charging a lipo heats it up; it's natural - and mostly correct! - to assume that charging when cold works. What these people don't know is that charging far below freezing damages the battery, which is why the firmware presumably is disabling charging altogether in such cold temperatures. If your EV is at 30% in the extreme cold, use some battery energy to warm it up a little (e.g. by driving) and then charge. If it's at 0%, you're stuck until you get it warm somehow.

instead some system that "runs the motor inefficiently to heat up the battery". Doesn't sound like this can work when the car is stationary

why not? isn't an electric motor just a big resistor? Give it less than the inrush current, so there's power spent but not enough to move. Obviously it'd be better to have the waste heat generated at the battery instead of at the motor, but discharge heating is better than nothing and battery resistance looks similar to phase resistance so it won't be too lopsided.

Teslas are some of the worst EVs out there but my ICE is also eating shit right now without a block heater (which are usually aftermarket and require an outlet to plug into). The engineering omission was not including a battery heater with external power - perhaps they assumed that if you were able to drive to a charging station you'd have enough power to warm the battery.

Weird, I just saw a propaganda article for EVs in canada during this cold snap, insisting that only the efficiency goes down a bit

LMAO bazinga Americans racking up another L.

Need sicko-train emoji

"NO ICE" to suck in ice real quick eh?

How do they not know? They bought Teslas, how do they not know!?

Why not make the charging stations semi indoors or something so that the cars can be externally heated, seems like badly designed infrastructure

don't all teslas have a battery heating feature for shit like this? i'm pretty sure they do and these mindless consumers can't even be bothered to read a 80 page book on their $40k+ car

also can't believe i'm quasi defending teslas here. please view it more as point of clarification before i puke more

But how could the car system even know how cold the batteries are? Are you some kind of wizard!?
