Ok, so sounds worse case like you’d want to put in about 50 kWh from 11pm until 6am, or seven hours. That’s charging at about 7 kW, or 32Amps. So ideally, you’d use a 40A breaker and dial your EVSE in at 32A.I do about 60-100 miles a day (self employed).. some days I do 20 miles, somedays I can do 150.
But that’s worse case. Most of the time, looks like charging at 20A would work. And if your battery ended up low, you could always start charging earlier in the evening.
