alt Hacker NewsI have a standard plug (not even three phase) and charge 30 kWh in ten hours (overnight). That's around 90 miles, which is plenty.
If I'm going on a long trip, I just make sure I start charging from > 50% the previous day, and I'm good. It's trivial to manage the state of charge when you have a charger at home and a planned trip coming up.
In the U.S. our standard outlets are 120V, so you only get about 1kW or so out of them. Plenty for most people, but annoying if you need >50 miles of range a day, or if you want to boil water in an electric kettle. The situation is much better in Europe, and most of the rest of the world, where you have 220+V
