Is there any danger to the battery in 95+ degree weather? I am often unable to find cover from the sun and do multiple short trips during the work day. Will this hot weather cause degradation even if I’m not fast charging?

The battery has active thermal management so you’re good. This is really only an issue with Nissan Leafs and older EVs without proper battery cooling.

Agreed, the BMS will handle it for us. The ID.4 does not even start active cooling the battery until it reaches 95°F (in vehicle operation) or 86°F (during charging) which further shows its not a problem. But it will lower your range if you are running high AC, and it also needs to cool the battery, motor and electronics.

I've also been wondering about this: I live in an urban downtown, and park on a street. Any car gets quite hot -- especially one with a panoramic sunroof!

One related matter I'm wondering about: I know there's value to pre-conditioning when it's cold out. Does the same hold true for heat? In other words, does it make sense to remotely turn the A/C on 10-15 minutes before leaving so as not to put that added stress on the battery at the start of a drive?

The ID.4 has a radiator with coolant running inside of it to cool down the battery (or heat it up). Hot weather is nothing to worry about.

Manufacturers test their vehicles in extreme hot and cold climates as well as salt-fog, etc. I feel we can well trust the VW engineering.

However anytime the vehicle has to draw add'l power to keep the battery cool or warm will of course impact range. No free lunch.

When VW was doing the testing for their batteries, they tested it in the summer in Arizona. The testing was done last summer which was the hottest summer on record. the batter management system work perfectly. So you should have no problem. Plus the battery has a 100000 mile warranty
