As someone who has driven the complete breadth of Pennsylvania (300 miles) dozens of times in my life in ICE cars, the rule is that you add 30 minutes of stoppage per 3 hours of driving, in order to stretch, use the bathroom, refill your water bottle, get snacks, etc. As long as an EV can fill 3 hours of charge (180 miles) in under 30 minutes, charging time adds nothing to the trip. The only thing that matters is that rest stops have adequate charger capacity.
