8 hour drive averaging 50mph(to be conservative and easy math) for 8 hours is 400 miles. What EV can go that far?
Assuming you charged before you left
Charged midway
Charged when you got there
You charged three times for an hour? Even not counting the first charge, you'll absolutely need the last when you get there. That's a min 2 hours charging for an 8 hour trip or about 25%.
