The J1772 spec maxes out at 80 amps ( 19.2kW at 240V ), which would require a dedicated 100 amp breaker in the service panel and appropriate sized wiring. 30kW is DC fast charger territory, which is cost prohibitive for home install at this point. I would love to see Solar DC direct to CCS DC units, but as far as I know such a thing is not commercially available off the shelf.

I agree that a NEMA 14-50 (aka "dryer plug") and removable EVSE set to 40 amps (9.6kW) would fit almost everyone's use case for overnight charging just fine, even on a thirsty EV truck.
Keep in mind even a Hummer EV is hardware limited to 48A right now … and it’s unclear if 80A charging on future Hummer EV’s will require the specialized PowerStation.


I suppose if someone’s first EV is going to be a Silverado, they should wait to see which EVSE to install. Although I’d imagine many homes would have a hard time fitting a 80A EVSE within a NEC load calc.
