@yaypie 's Model 3 thread got me thinking about EV charging, and I was wondering--Isn't it possible to create a home charging station capable of the kind of bulk charging that Tesla's 480v superchargers are capable of putting out? They're able to crank out 120KW of power at the plug. I don't see why it couldn't be done.
Most of the conversations I've perused on the Internet seem to be focused on what kind of grid electrical service your residential house is getting from the electric company. Hoping to get 3-phase 480v directly from your grid supplier seems to be where every conversation goes. That...of course...is gonna be a show stopper. Nobody wants to run that kind of cable from the pole to a friggin house.
But that wouldn't be how I'd be doing it anyways. I mean...conceptually...I don't need 480v from the power company. I just need 480v *at the plug*. If I've got a power station in my house...say a bunch of big-ass 2v cells, storing up power all day from solar panels...that comes in as anywhere from 16~22vdc. I can upconvert and downconvert that any way I want. And I only have to support 480v/1kW between the converter and the charging port in the garage. Why don't I see any conversation supporting that kind of strategy?
