There's enormous infrastructure around DC Fast charging.

Each one of those pedestals is able to dump 30 houses of energy into a car for 30 minutes continuously. And most sites have 4-12 of those things.

It's not a minor engineering task. Add to this that commercial electric billing is often based on your 95th percentile draw over a small window of time, so if you have a station with 12 pedestals and the circuits comes to town, say 12 Electric Hummers, you could end up with an enormous bill.

Home charging, on the other hand, is basically just a baseboard electric heater per house, so not difficult to manage at all.
