The Aptera Forum
The discussion, now, is whether it will be an AC unit and a resistance heater or if it will be a more efficient heat pump system.
And if there does end up being a heatpump will it just be for cabin or for the battery too.
@Daniel Watkins That all depends - I can't think of any EV that combines the power electronics/motor/battery system with the cabin system - although I believe there are some that use heat exchangers between the two systems. In Teslas - even those with heat pumps - battery heating uses resistance. I think problems with a single system would arise if there was a discrepancy of need: Say you're DC charging and need to cool the batteries but it's cold out and you need to keep the cabin warm while you're sitting there, charging. Or it's a rainy day and you're running the AC to defog the windows in the cabin but the batteries need to be heated.
From the "Performance" section of the FAQ:
Does Aptera have air conditioning?
It does, and it is very well insulated with its sandwich core composite construction. The solar also allows the interior to stay at ambient temps on hot days so you don't have to cool the car down before driving in the summer.
Noir Color looks great, but I worry about the extra heat it would generate in the heat of 116F in the shade in Las Vegas in August. I saw that too how they have a blower to let the hot cabin heat out in the back. You think that eats into the battery or solar? Cabin overheat protection, pre cool with an app maybe?
I ordered Noir as well. Central TX heat and sun is also no joke. It will undoubtedly use battery, etc. to keep up with the demand, but I think it will be fine/trust they are doing their homework. I'm not sure, honestly, any color is going to be any better when it's getting hammered by Rah! (Egyptian Sun God, not the British pejorative...) So, I'll take the risk for the cool blacked out look.
@SS 11186 agreed. Noir looks the coolest. I live in arizona so I thought of this also. I went with the full solar option as well and figured that with what little was left of the color on the top of the vehicle exposed to the sun that it wouldn't make much difference.
