You have a point; some EVs like the Leaf don’t even have conditioning. The Volt does have active conditioning, and being a PHEV instead of a BEV has battery charge and discharge limits which were limited by the factory to preserve longevity at the expense of being able to charge to a true 100%. If extra range is needed the ICE is activated instead of stressing the traction battery.
