The battery is heated to avoid that damage though. Nothing does this in an ICE car.

While true, how long can the car heat the batteries before it's practically unusable because the battery has depleted so much you need to charge it again before driving to work?

Since you likely have it plugged in while it’s at home. Perpetually.

What is the approx. power draw when the car is plugged in, fully charged, and the ambient temperature is around freezing?

Heating a 75kw battery up from -17F to 77F uses about 3kwh. So about 3-4%.

This is not a significant concern, frankly.

I lost a couple percent per day when leaving my car parked in 10°F weather. It’s about the same as enabling sentry mode.

If the car is plugged in– even to a typical 120V wall plug– it’ll charge and warm the battery even in single digit temps.

Some ICE cars have block heaters for this similar purpose.
