Comment on Norway on track to be first to go all-electric
AwesomeLowlander@sh.itjust.works 1 week agoI’m not an engineer. I’m pointing out that the real world is proving that EVs can work just fine in the cold, so your assertion that they can’t doesn’t hold any water. This was a recent article of interest, though.

Read over what you just wrote, and think about it for a second. If they have to be heated up to function, it supports my assertion that they do not function in extreme cold.
That 12% is not insignificant, and that’s just for the piece to keep the battery at operating temperature. The battery’s capacity and performance will also be severely impacted on top of that, even with it warmed up. These inefficiencies and workarounds add up to the point that they eclipse the inefficiencies in hydrogen production, as the hydrogen is not impacted by any such issues at the point of use.

The loss of efficiency in an ICE is roughly 15% in the cold as well.
There are enormous materials issues with storing and transporting hydrogen that don’t scale well
surph_ninja@lemmy.world 1 week ago
Why would they need to be scaled? Hydrogen is abundant in most corners of the globe. It can be farmed on site, as needed.

They function at a 12% range loss. That is a far cry from ‘do not function’
No it’s not. It’s total range loss, not battery capacity reduction. The car gets 12% less total range, that’s the final figure taking everything else into account. You seem to have made up your mind about what you wish to support and are dismissing anything else that does not support your PoV.

Then don’t heat up the battery, and see if it runs. Won’t work, because EV’s have to heat up the battery to get it working, because they don’t function in extreme cold.
And while we’re at it, what’s the workaround for the batteries catching fire and exploding in the extreme heat of summer? We need to implement some cooling pumps while we’re at it?
Or just skip all of the complexity, and use abundant & clean hydrogen.

You’re incredibly confident for being so blatantly incorrect.
We had negative 30 C last winter. I drove my EV to work every single day. When the batteries were cold I had reduced power available, which made no difference at all as it was -30 C and snow everywhere.
Using the battery also heats it up. Zero pre-heating of the batteries. I can literally watch my available power return while driving normally.
If batteries wouldn’t work in the extreme cold, they would not be able to turn over the starter on your ICE car either, which it very clearly does….
You are literally arguing against something close to a million people do in Norway every single day between November and March. Open a map and look how far north we stretch. Oslo is as far north as Vancouver. People live and drive EV’s in Hammerfest.
So please, just stop. You are dead wrong about batteries/EV’s, but take this chance to learn something new.

WTF is wrong with your logic process? Why would you remove a key component of the car? Lets take the starter out of ICE vehicles. Oh hey, they don’t function in any temperature at all!
The point is clear that ICE vehicles work just fine if properly engineered for cold climates.
Would you like to bring sources to this discussion? Here’s mine.
Oh, were you just pointing to 1-in-a-million incidents as reasons to shelve an entire technology. Tsk.
There’s nothing abundant and clean about them in the current car ecosystem. I’ll grant there’s a possibility of that, but that doesn’t mean much when the competition has already delivered.
