The basic protocol from an AC charger to your car is, "hello, I have X amps available, don't take more or you will trip my circuit breaker". The car responds by charging at or below the current advertised.
When you charge in a context where the car unlocks the charger (i.e. Tesla Supercharger), the protocol must divulge the car's certificate, signed by the owner of the charging network (like mTLS). There would be privacy-preserving protocols for this, but they are not used in practice.
I'm very curious how they are managing "no screens".
I thought all vehicles in the U.S. were required to have rear-view cameras for safety. I'm curious how they are getting around that.
Edit: I now see that the article speculates that maybe there's a screen in the rear-view window for this. But I can't find anything concrete.
My understanding is that the regulations require a certain amount of rear visibility, either directly in the mirror or via a rear-view camera. But the former likely wouldn't be possible with the bed in the way.
I've asked before but still not sure how much information is given to a charger when you plug in an EV?
