“This brings up another question re EV’s: How do their batteries hold up re ACing a car when it is over 100 degrees outside and hotter on our roads?”

I posted some data a few days ago. I will summarize based on memory, only.

Actual usage reports indicate 500-1500 watts steady state. More if car has to be cooled down.

Generally, less than 1000 watts for nominal 90 degrees. Tesla says their new design is better.

Using 0.25 kwhr per mile no A/C and driving 60 mph for one hour:

No A/C = 15 kwhrs

With A/C = 16 kwhrs

Assuming an 85kwhr battery range drops from 40 miles to 318 miles.

Thanks that isn’t too bad.

Of course how many businesses provide covered parking to reduce the heat gain in parked cars, during the day?
