In reality it's the opposite. Laptop and phone batteries have limited temperature control, maybe a fan. EV batteries have active thermal control loops that heat and cool the whole battery evenly.
The 'exception that proves the rule' is the 1st gen Leaf, which had passive thermal control and poor longevity.
EV batteries are slightly over-provisioned (like most devices), but they also provide more tools to manage lifespan. I'm continually shocked how my Apple devices have no ability to limit charging to 80 or 90%. They're just constantly frying the battery.
