I live in central Florida where in summer the temp is in the 90's every day. Right now the temp is 92 in the garage. Interior temp on the car is 90. I also park outside three days a week and it gets really hot in the car. I can cool the interior down to 80 I suppose but will that help to avoid battery degradation? At full charge the app show 268 miles instead of 271. Car is five months old with 6,000 miles. 240 volt charger in the garage.
