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)
Yes. You set it up based on some serialization of the car and the next time you plug in it just charges and bills your account.
Electrify America is setting up something similar but so far it doesn’t work with the Bolt or some other older cars. Something about what they are using to serialize the car isn’t compatible with older models. So be sure to check the website of the charger for more info. It will probably become more standard with time.
