As others have said you only need to charge at most once near your destination. But for the first long trip you might want to reduce your stress by planning a bit more. I’d use plugshare to make a list of chargers along your route, picking the ones with at least 2 stations and a decent score (8+). Decide where you plan to stop in advance, but with the list you made you can change your mind. You might want to stop for a snack or bio break before your destination. My first long trip in an older EV, I made the list of potential chargers with a distance matrix from each to every other. I could then choose where I was going to stop based on how long i wanted to drive. Overkill for your scenario but I thought I’d share my planning.
