I don't care for the cabin temperature as long as it doesn't affect the battery. Last summer my Leaf spent most of the time on my driveway (concrete but with direct sunlight in the afternoon). It wasn't parked on asphalt but the battery temp bars were usually at 6, a few times it hit 7. I know the bars aren't really helpful but I can't think of anything else than heat that beat it up.
Would placing a large piece of cardboard under the car while parked on the driveway keep the battery cooler? Or should I invest in a tent of some sort to provide shade to the car and driveway? I'm open to any idea.
Definitely park in the shade whenever possible, but if you have to park in the sun get one or more reflective window screens. I normally aim a car's windshield directly towards the sun (or where it will be late afternoon when the angle is lower and more direct) so that I only need a windshield screen. If you have to park sideways on, then getting some for one side of the car will be helpful. It will definitely keep the inside of the car cooler, and whether or not that high cabin temp significantly affects battery longevity, it will definitely affect the amount of energy expended to cool the interior down to a comfortable level. It may also improve the life of the vehicle interior (dash, seat fabrics etc.), and may also lessen outgassing of any nasty chemicals that might be included in said interior. It's a lot less hassle than a full car cover, although that would be the most effective. A white car already has a high albedo (see https://phys.org/news/2011-10-silver-white-cars-cooler.html
), so it's the windows (and the pavement, as others have noted) that are going to be the main cause of solar heating.
