Fast charging batteries is an improvement. But the second issue is power. Most homes have a 150 amp service. Charging a 100kw battery with 100w still would take 1hr. The easy fix is to have a battery bank do the charging, and recharge it as power is available - but that works for a single car. Even a small gas station tends to have 4 pumps and can fill 40-50 cars an hour. That much power is more than 1/2 the electricity my town currently uses - I can not really imagine needing a completely new set of transmission lines to each small gas station - each gas station would all but need their one substation. Buckees would need a power plant next door.
We would need to completely rethink our current grid. Honestly unless we start putting mini reactors under the station - I hardly see this happening anytime soon. Have not heard much about container sized nuclear power plants for a while - and OMG the dems would never allow that. A half dozen years ago or so did read about 1mw modular plants - but crickets since then. But honestly, my home town probably has over 100 houses with 100amp services. 1,000,000 watts - That is what a new electrical "gas" station would almost need (or several stations, if they could average load over 24hrs). Buckees would need a few...

Wonder - does commercial transportation use more gas now than private vehicles? Imagine needing to fast charge all the tractor trailers and trains...
