Does anyone know why we are limited to 9.6kw in the US? We are not offered the 11- or 22-kw options either.

Seems strange, I would prefer to have the option to charge faster at home.

I don't know but it doesn't bother me.

I am not too concerned either just interested to know why. I am thinking it must have to to with the US power grid vs UK.

Not sure. I know the F150 lightning can accept 19.2kw from a Level 2 charger.

Right, and I have a ChargePoint wired to deliver 50 amps on a 60 amp circuit, but I guess I won't be able to use full power. I would be fine with 11kw but 9.6 is ok, just a couple hour difference per night.

Even at 9.6 kW per hour, you should have all the juice you need after a night of charging and keep in mind, slower charging is better for battery health. I also installed a ChargePoint Home Flex, but we went with a NEMA 14/50 and a 50 amp circuit so I’m capped at 9.6 kW per hour charging anyway.

I found out why we don't get 11 and 22k options in the US. It requires 3 phase wiring and residential homes in the US are primarily single phase. Ford and other manufacturers onboard chargers don't require 3 phase wiring. For example, the IX can accept 48amps single phase. The EQS can accept 40 amps single phase, that's fine, it's like 7 miles per hour of charge difference.

And better for your batteries health.
