Well, that's it then. I'm wrong. When I show you a heat pump that can work down to 15°F, to you it doesn't exist so I'm wrong.
Even when I concede (before your first post to me no less) that below that temperature then resistance heating is required, to you I've made no such concession so I'm wrong.
You win.

EV batteries are sensitive equipment, and they need to be kept at a certain temperature in order for the EV to run well. Most EVs will consume power to heat up its battery, and as such, heat pumps can help out here too. In fact, efficient heat pump designs can warm up the EV’s battery without spending that much power, as it instead can use waste-energy from the EV’s motor.
On top of that, the temperature of an EV battery can affect how fast it charges. In order to speed up the charging process, some automakers precondition their batteries so that they will hit the optimal charging temperatures and deliver a fast charging experience. Once again, this is another area where heat pumps can play a role, as they can heat up an EV’s battery and precondition it for the optimal charging temperature.
No, when you are trying to discuss a topic with someone who tries to “win” an argument with misquotes, mischaracterizations, and playing the victim you don't really win.
You still don't even understand the points that I was trying to make or why I was trying to make them... A “heat pump” could no doubt be designed to extract the “heat” from liquid nitrogen. Whether it would be practical for anything is another matter.
The discussion in this thread was about how well EVs held up in the recent cold spell. There is no doubt that heat pumps will play a role in increasing efficiency of EVs over time, but they certainly had little effect on the performance of EVs in the recent cold spell. You were asked repeatedly to provide specifics to back up your claims but never provided any relevant info.
