Japanese firm believes it could make a solid-state battery with a range of 745 miles that charges in 10 minutes

    That is about 2.2X the range of a Tesla, so figure 2.2x the battery: 68kWh x 2.2 = 149.6 kWh. Divide that by 1/6 hour: 900 kW(!) at 240V about 3750 amps. We gonna need a bigger charging cable! lolz

      Many charging stations are operating at 480V so that helps a bit. We may need to bump those numbers up though as EVs become more and more prevalent. Don’t transmission lines carry 10-100kV?

      At those capacities and charging times there’s no chance of it not being some medium voltage (4160v or higher) equipment. Even a 480v 3ph low voltage building power system wouldn’t be realistic because a single charger would be more than double the service size as the entire remainder of the gas station. However it would be done this would need a massive upgrade in electrical that isn’t going to be available at your neighborhoo station. Also raises some safety and logistics concerns, you can’t trust the average person with that degree of potential hazard.
