And, of course, adding more level 2 charging at the curb.
You have to take human nature into account.
"I'll just get gas in the morning"
Requiring careful planning and dedicated charging at home isn't going to lead to an electric car revolution.
Do that, and you'll end up with more than enough charge for daily tasks.
I drive an EV and the only time I worry about fast charging is on road trips. Which, for me that happens once every and a half hours while driving (approximately) and gives me a 30 minute break to wash the windshield, grab a snack, use a restroom.
All in all, not really a big deal.
That, to me, is why it's overblown. With cars getting even longer ranges, it becomes even less of an issue. The first EV with 500 miles of range will be a game changer.
Also importantly, the more complex the cable is, the more expensive it will be to replace if someone comes along with some bolt sheers and clips the cable.
Our "current" (pun intended) cables can deliver 350kW of juice. That's already more than most car battery chemistries can accept for more than a few minutes before doing harm to the battery.
Not to mention the fact that even if you could deliver such high amounts of power, that'd translate into insane requirements on the grid, likely necessitating onsite storage to act as a buffer.
All in all, the recharge time problem is overblown. There isn't as much need for high speed charge infrastructure as you'd imagine. That's because most charging is happening at home at lower speeds. Your car almost certainly sits idle for more than 8 hours every day which is plenty of time to refill. Fast charging really only matters for long range excursions, which aren't terribly common.
