I'm just going to leave this right here in case it helps with calculations:You keep connecting so called output battery efficiency with input charging rates. I disagree. Model 3 Tesla vehicles can only charge faster if a software upgrade exists and is applied for the level 3 charging rates. Clipper creek posts different charging rates for the Tesla vehicles with the 11
5kW on board charger than what you have stated. The mach e has a 11.5 kW on board charger. I say mach e on a 50 amp breaker with a larger evse charging cord than the Ford mobile charging cord will get more miles per hour of charging.
Mustang Mach-E has a 10.5 kW on-board charger
