Dude, electric car’s are about 25 computers on wheels. Adding a “charge between hours” function is so trivial I would be surprised if it doesn’t already exist. But no, you’re right, computers are a complicated pipe dream, we should all go back to coal burning, steam powered, difference engines and horseless carriages.
I own an EV and there’s definitely a setting in the car to specify what time of day to charge (and my charger itself also has an app where I can specify that time restriction).
Panel and code calculations don’t care about those yet and it’s going to be a long time until they do.
It’s fun seeing someone with so little understanding of electricity spreading the misinformation someone else fed them.
Most houses existing panel have the capacity for a level 2 charger.
Codes and standards need to adopt those functions, right now there is only a couple of code complaint ways to deal with it on a panel end.
Can you explain why that matters if the hardware at the charger could initiate and control all that?
