—”Can he charge more then one EV?”
YES...BUT.
Unsure about the newest equipment.
Usually, one charger is needed for each car. To charge them simultaneously two chargers are needed.. You can charge other cars at different times.
And you CAN NOT exceed the main service rating.
Here in DuPage IIRC, it is 100 Amp minimum residential service required, 200 Amp is common.
Tesla chargers come in different levels that require different circuit breaker sizes.
IIRC 50 amp and 100 amp.
My daughter and family added an addition to the house and while everything was open they added a 100 amp service to the garage. The son-in-law did most of the work and had an electrician pull the permit and check the work.
The wire was the big expense, PVC conduit for underground and disconnect box in the garage. He dug from house to garage by hand.
The material was less than $500, the electrician was a friend.
The Lv2 charger is about $400, draws ~40 amps and needs a 50 amp breaker.
Thanks for all that. I only know what I’ve been told by a couple of folks who had them professionally installed.
