I posted about this a week ago. The battery pack will likely be around 150kWh (Nio has a solid state battery car that will be produced that can do 577 miles on a 150kWh battery). The 9 minute charge is from 8-80% (according to the marketing material I dug up) so it is 432 miles of charge in 9 minutes. Considering fast charge costs like $0.50/kWh currently, I'm guessing most people will not be charging up that entire portion unless they are planning on driving for a long fucking time...after they have already been driving for 9-10 hours.

But that charge rate would have to come from a charger that can output much higher than current ones. The highest output you are likely to find is 350kW which would take 18 minutes to charge that 108kWh. So while this battery can charge that fast, you are not likely to be able to find a charger with that high of output for a few years. Still great to be able to get a couple hundred miles of range in 9 minutes. Solid state batteries supposedly have a quicker ramp up period and can take the full output for a higher percentage of the battery.

You know, with charge times like that I wonder if roadside attractions will become more popular again.

Maybe I should start on the next worlds largest rubber band ball now.

Well most people are not needing to add over 400 miles when they charge up. That might be the case once a year for occasional families but most will be looking to add half that which is not much more time than it takes to fill up with gas. It might cause charging stations to offer more amenities. Or maybe the government could get off its ass and make it okay to put them in at rest stops, there wouldn't be much of a problem at all.
