Re: "GM is projecting an all-electric future..."
Also your 100kW charges ain't going to happen because where has an electric supply that will support that? You'd have to replace the local substations, the cables to the house, and the internal fuseboxes
There's generally no need for fast charging at home; that's what one would want at a motorway charging station, twenty minutes to put two or three hours of motorway driving into the battery. At home you can plug in, and in most cases there'll be ten hours available to charge. Also, you just plug in every time, whether the battery is empty or not, or even still three quarters full.
