There is no way to communicate when you are charged up that way, maybe via an SMS that you add with your phone number. Also, you have to communicate your charging preference somehow. It’s not like pumping gas, you rarely want it to stop at 100%, although the charging standard might at least be able to control that from the car.

True I see what you mean, but that would seem to be an easy function to build into the car’s charging controller. I’m not sure how it works today but I would imagine most cars have a “stop charging at x%” function already without depending on the charger for that.

Ya, I think they even get status otherwise I’m not sure how electrify America’s app works in the first place.

I once charged at an L2 in Canada that involved a QR code, and then payment via a web form. In that case, a POS would make the setup too expensive compared to just putting power out there with a networked microcontroller.

Cant' the car do it?

Or ya know.. the pump, like has existed for decades..

I thought the problem was that it takes long enough that you aren't by the "pump" during process. Also that the chargepoints are likely less infrastructure than a pump. So something has to contact you (SMS/email/whatever)

Yeah... cars come with internet connections these days, I'd say it's the car's job.
