As mentioned, using the car's navigation system is seamless. It will tell you when and where to stop, and when you are ready to leave so that you make it to your next charging stop or your destination. But that is only going to get you there. If you plan to drive around the area you are visiting, you will need to account for that by charging for longer at the stop prior, or making a stop near your destination.
Also, there are some rules of etiquette that are worth following. I have never take this route so it is possible that they do not apply. When you visit an older V1 station, chargers are paired in a way that they share power which means two cars connected to the pair will charge more slowly than if only one were connected to the pair. The chargers will be marked 1A-1B, 2A-2B, etc. If there is already a car at the A pair and none at the B or C pair, don't park at the A, go to an open pair. At some point in time this may not be possible and nothing you can do but something to think about when you enter a nearly empty station. Also keep in mind the pairs are not always next to each other. Newer V2 stations don't share power so not an issue.
