> plus the batteries lose > 40% of their range in cold weather [2]

The link you cited does not mention cold weather range loss for batteries. Can you provide a source for this claim?

Oops, citations [1] and [2] got mixed up. This is the correct link: https://apnews.com/article/04029bd1e0a94cd59ff9540a398c12d1

Thanks! From the corrected link:

> At 20 degrees, the average driving range fell by 12 percent when the car’s cabin heater was not used. When the heater was turned on, the range dropped by 41 percent, AAA said.

So the majority of the range loss in cold weather in passenger EVs was due to heating the cabin. Do you think an electric semi would also require 30% of its battery capacity be dedicated for cabin heating in cold weather?
