You've either pretty much never seen any recent-ish battery teardown or you just weren't paying attention to them. Acting like active cooling is some rare oddity in EVs is pushing a falsehood. It's an argument not based in reality clothed in the slightest amount of deniability by acting like you're someone who would be informed (supposedly watched some significant amount of teardowns) but just haven't happened to see it at all.
> would take it's toll on the battery itself reducing both range and requiring more charge cycles because all those compressors need power too.
You're largely misunderstanding the amount of energy needed to actually operate the car at highway-ish speeds and the amount of energy needed to keep a battery pack somewhere in the range of acceptable temperatures. You'll use far more energy maintaining the cabin than what you'll spend managing the battery in the majority of climates. And even then the actual locomotive power needed to drive the car still dominates the overall energy usage.
And FWIW when it's really cold or hot my battery preconditions using wall power so it's leaving the house at a good temp. Then it's a pretty solid mass of stuff, a good amount of thermal inertia. So it's only those trips where it's been parked for a long while and it's fully cold/hot soaked that it's really using much of the battery. And even then it's still far less than even 25% for all cooling (cabin + battery) energy use of it's overall usage even when it's >100F out here and is totally heat soaked.
And even then, assuming it's not over 100F or under freezing a lot of the cooling needed for the battery can be done by regular radiators and airflow without needing compressors. If it's 50-90F outside it's probably just cooling itself by airflow over a radiator for the liquid cooling loop so all it needs is a water pump circulating, maybe a fan. It's not like there's massive amounts of waste heat being generated like in an ICE.
