Wow, that is impressive looking isn't it? Or how about this one?
If only Doc Brown had these types of animation tools available to him... I am pretty sure that a DeLorean would be parked in every driveway.
From one of your links:
"Heat Pump is an efficient technology using heat source from ambient air. Heat Pump can generate large thermal energy with little electric energy. Electric energy saving for cabin heating can extend driving range of Battery Electric Vehicle or Plug-in Hybrid Electric Vehicle."
What a revelation! I am sure that no one here had ever heard about that before.
And look how smart these Korean guys look!
But didn't those Germans come up with a nice picture...
What was the point of the last link that you posted to a training facility? It is from March of 2021 and says that heat pumps are a game changer for EVs... OK. None of the info you linked to provided any information about the topic that the thread was supposedly based on... how did the EV fleet hold up under severe cold conditions, or even how did heat pumps built into them fare.
You don't know much if anything about the topic, but you are blissfully unaware of what you do not know. The Dunning-Kruger effect effect occurs when a person’s lack of knowledge and skills in a certain area cause them to overestimate their own competence.
If you consider a link to a component manufacturer (Denso,) an automobile manufacturer (Hyundai and Volkswagen) and a professional society (SAE) to be "promotional material," then yeah, I guess so.
To recap, you said in your Post 42 "Unless it is extremely cold outside... then they basically don't work. This is why heat pumps in places where it gets cold frequently are backed up by conventional heating. It sounds like whoever tutored you on this subject left out a minor detail or two."
However, I said in my Post 29 (posted prior to your snarky comment) "They still work more efficiently than resistance heat down to about 15°F. Below that then resistance heating provides additional heat, just like home heat pumps."
Our exchanges after that is just your continued failed attempts to be condescending.
