A good rule of thumb across most makes is to take the EPA range number and multiply by 0.85, and that’s what you’ll get at a constant 70-75 mph in moderate weather (say, 55-85 degrees) with the climate control on.

Of course, you probably want to arrive at your next charge stop with 5-10%, and the top 10% of the battery charges very slowly in all EVs, so you normally multiply by another 0.80 factor to take that into account.
