Math does not work here: 8h x 2kW = 16kWh. Tesla has 60 or 100 kWh batteries. It only works if you take only short trips (like commuting to work) and never go below 70% of charge.
- adrianN 4y agoIt works perfectly fine if you plug in every night in your garage and don't drive more than 100km a day. If your commute is longer you might need 3 or 4kW, but probably not 11kW.

No advance planning, no compromises required. Also, I'm curious: in my country it is pretty common to have 11.5 kWh installation at home (it was even before advent of electric cars), is the US somehow limited in that regard?
- pandaman 4y agoAmerican mains are single (split) phase 240v, your country's are likely 3 phase 240v. Your appliances are likely hooked to 3 phases simultaneously with a 20A breaker so they can get 12kW, American 20A hookup is only good for 4 kW (240x20x0.85 because you cannot draw more than 85% of max power continuously by code).
