The bad advice here is astounding me.
to answer your question, assuming you are buying a Tesla, have your electrician wire up a NEMA 14-50 outlet. That will take 2 slots in your panel, much like your AC.
All Tesla cars come with a portable connector that includes 14-50 plug and a normal 120v wall plug l. Any of the other plugs/adaptors will cost you extra.
Or, if you decide to buy the Tesla wall charger, which costs extra, you can wire that up directly in Lieu of an outlet. However, be aware that wall charger will be useless except for charging a Tesla.
I recommend people start with 14-50, as it is lowest cost option.
Tesla no longer includes the 14-50 plug with the mobile connector and you need to purchase it separately for $35.
