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?
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.

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.
