I don't own an EV yet so have a pretty basic question.
Do all charging stations need smartphone (app) to use? Can I just drive up to a station and pay to charge? (If yes which network)
USA specific (of others r interested just add international info as well)
If you're worried about privacy, they can already tell who you are by your car's data. Avoiding using a smart phone for charging will just make charging more difficult for no personal privacy gain.
You don't need app to charge. You can usually pay by card or if you don't there is a QR code on the charger that redirects you to a website where you can pay and start the charge online.
