My practice is to plan routes using ‘PlugShare.com’ but there are others. The protocol starts with getting a free account and setting a filter for the fast DC charging plug of choice. Configure your vehicle in the App with maximum, practical range.
For each potential trip, enter the start and end points. Then add fast DC charging stops to complete each segment. If planning to stay in a motel, add L2 stations for overnight charging with a free breakfast. With a Tesla, many shorter charging sessions will be faster block to block time than fewer deep charging sessions as this can use the faster charge rates below 30-50%. Save the route and check comments to eliminate marginal chargers.
So I have saved routes to my Mom, important friends and relatives, casinos, and vacation spots. The night before I recall planned trips and check recent comments while the car charges to 100%. An ideal route has ~120 mi between fast DC chargers at mini malls for biology breaks.
