Experience with Heat Pump in Really Cold Weather?

That could work. Never saw one like that. 48VDC - where would a thing like that be used, I wonder?

Not neccessary 48V, just including the page I pulled the image from. Tesla's would be brushless.

Watch this. Look like 0 degrees F is when the heat pump will lose its efficiency and then become as efficient as the previous resistance heating technology in the Model 3/S/X.

That's a great video. Really helped me understand how the process works.

I understand the Tesla wouldn't use a 48V, but I wondered what applications would do?

Oh! Gotcha. I think 48V is common in automated guided carts and other terrestrial vehicle systems (forklifts, golf carts, neighborhood electric vehicles)

Datacenters are 48V

They're probably some of the biggest energy loads these days and squeezing efficiency is paramount.

Totally agree. That was super helpful.

Would really see a side by side graph of efficiency vs a model 3 by temp.

Coldest day so far for my Y has been 40. Seemed to work great, got about the same mileage as a 90 degree day and AC. Clearly worse than a 70 degree day, but not enough to be a huge deal.
