Every EV charger I've seen seems to be a mix of vendor lock-in (Tesla) or you need to have an account linked to a financial institution or credit plan before it will allow you to use it.
It would be nice to just pull up, prepay and plug-in but but the paranoid side leads me to believe they want you to sign up for an account specifically because they need to make you pay for the energy you use, plus they want your aggregate account information for marketing value.
