Hey good morning Everyone,
I have the Tesla Wall Connector installed at my home on a 100 amp breaker using 3 gauge wire.
When I plugged in an older Model S (not sure of the year, maybe 2016?) that I had as a loaner car, the car only allows up to a maximum of 40 amps on the display when plugged in. When I plug in the current loaner I have (2018 or 2019 Model 3 Performance), that screen shows a maximum of 48 amps.
I'm not very knowledgeable about these electrical things like this but I have 2 questions:
1) Why would the 2 cars have a different maximum amp amount?
2) I thought having a 100 amp breaker would allow the car to charge at a much faster rate/have higher max amp amount than 40 or 48. Is that not the case?
Thanks so much in advance!
