Lithium car batteries are no different from lithium cell phone or laptop batteries. Everyone who has ever owned a portable electronic device knows this is total bullshit... and laptops don't sit outside and go from hot to cold constantly or use battery charge to keep themselves cool in the sun.
Its hard to know how comparable it is. Cars also have a lot of cell management features and cooling to promote longevity. It just depends on if you believe the state they are publishing, this used car buyers guide seems like their market position would be enhanced by accurate data so I don’t have reason to believe they fudged the numbers
If you think spending the energy in the battery to cool the battery (aka: using the battery) is going to fix battery degradation I have I bridge to sell you. The cooling feature actually exists so that when you get in the thing and start it on a hot day it doesn't catch fire and incinerate you.
