“Norway is the world leader when it comes to the take up of electric cars, which last year accounted for nine out of 10 new vehicles sold in the country.”
“Norway is the world leader when it comes to the take up of electric cars, which last year accounted for nine out of 10 new vehicles sold in the country.”
Given that we’ve moved almost all of Norway to EVs, that’s obviously untrue. So if you re-examine that assumption, what new conclusions do you come to?
So what’s the secret sauce? What profound technological steps forward have they made?
Or are they just heating up the battery, and eating further into the already severely impacted battery life?
Secret sauce is Norway gets money the same place Saudi Arabia does: gas and oil. They have really good resources to do whatever they want and unlike dumb countries like saudi arabia or russia they manage it better.
I’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.
https://arstechnica.com/cars/2025/01/cold-weather-range-hits-arent-as-bad-for-evs-with-heat-pumps/
If you’re using heat pumps, and not resistive heating for batteries, looks like the range loss can be as little as ~12%, which is pretty insignificant.
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 minimal 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
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 article even states that the majority of that range loss is due to heating the cabin, not the battery. Which ICE vehicles would have to do anyway. 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.

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.
When did I claim they’d work without a starter? You claimed the EV’s work in extreme cold… by heating them up. So they don’t work in extreme cold, which is exactly why they must be heated up.
We’re not talking about global averages of EV batteries catching fire. We’re talking about the increased risk of them doing so in extreme heat. Since we’re in the middle of climate collapse, and greenhouse gases are continuing to accumulate, more and more areas will be experiencing extreme heat.
I’m not saying there’s no place for EV’s in cleaning up our planet. But demanding we commit to only EV’s, and just ignore the areas of the planet they can’t perform in, is absolutely asinine. Especially when we have the hydrogen tech ready to roll out.
You’re being ridiculously (and inaccurately) facetious. EVs refer to the entire car, not the battery alone. If anybody had claimed the batteries work just fine at cold temps (which nobody did), that’d be a different matter. EVs designed for cold climate work just fine in those climates.
To begin with, that was not part of my original discussion, and I have little knowledge on that issue. However, since we’re on that, can you show some sources that there’s a significantly increased fire risk in summer, and how that compares to ICE vehicles? Based on the info I linked, they’d have to increase by several orders of magnitude to be doing worse than ICE vehicles.
Who demanded that? This conversation started when you claimed that EVs couldn’t work in cold climates, and that’s the only thing I’m really taking dispute with.
