I have one of those cars (Kia EV6), and when at a 350kW charger, I've never seen it go over 180kW. As for every 2 hours, that's only true once there are more fast chargers, especially on long stretches of freeway between major cities. I did a drive from Houston to San Diego, and we had to stop every 60-90 minutes, not because we needed it, but because the fastest charging locations (Electrify America) weren't close enough to skip any. Also, freeway range is far less than city range, due to wind resistance.

Wow. 400A * 440V delivery is 176kW. I didn't know that was already standard for commercial fillups. How long does it take to fill up with that? Is a "3MW charger" of GP a bunch of these at once? Or nominally a bunch of 2x these (350kW delivery) that typically only do 180kW for safety conditions or compatibility? I guess they are already being spec'd for "as fast as gas", now they just need to be as prevalent? (and work at a full 350kW, but that should come with time and improved standards)

  There's a few different standards being discussed, with battery buffering being a major component in most proposals. Using 2 750kW bays for a truck was one proposal. There is a limitation imposed by the size and cooling capacity of the battery too, although that improves every year. The current marketing buzz phrase is 20 minutes to 80%. Daimler is proposing 3,000A and 1.25kV https://insideevs.com/news/535918/megawatt-charging-system-ev-trucks/ https://insideevs.com/news/535918/megawatt-charging-system-e...
