I wound up in a rental for close to two months last fall. The Electrify America chargers took credit cards but charged more. It looked like you could also get an RFID card that identified you and billed to the account on file at the lower rate. I used another weird DC fast charge that was part of Shell’s network and related to Duke Energy that was app only, very annoying. I used a level 2 from ChargePoint and had to use the app. The cell service didn’t matter; it was deep in an underground garage with no signal. I had to go out to download the app, then came back in to initiate the charging session. It was annoying to do in the moment, but once the account was set up worked pretty easily, and it looks some of those apps work with other networks. I think it would be okay as long as I was signed up on a few networks, but I’d really rather be able to just tap my credit card and go, no signup needed. That was part of the IRA, but it’ll take time to roll out.
