Has anyone measured how much current their house is pulling from the grid when the Model S is on charge? Would your local utility allow 22 kW+ assuming the house is on a three phase connection and the Model S is equipped with twin on-board AC chargers? The limits in WA are around 14 kW for a single phase connected house and around 21 kW for a three phase connected house. And what about households with two electric cars? Even two BMW i3s pulling 7 kW each would max out a single phase connected house.
