The peak charging power during the test reached 1100kW, and even after the battery reached 80% SOC, it still maintained over 500kW.

I can't even imagine, I'm happy to have 6kW free charging daily and was blow away one time I used a 50kW charger when I used my car a bit more over a weekend and needed a little juice to make it back before Monday

1100kW means 18.3 kWh/minute, which for a 3 mi/kWh car is 55 miles (almost 90km) added to a car's range in just one minute of charging. For a 4 mi/kWh car, that's about 73 miles (almost 120 km) in a minute. That's wild.

A gasoline pump delivers about 10 gallons per minute, so for a 25 mpg car, a gasoline pump gets about 250 miles (400 km) per minute, so there's still a gap. But the gap is shrinking.

Pushing 18.3kW a minute is not going to end well when these vehicles age. These batteries are going to carry a stupid amount of power for no good reason. In a crash , all that energy will want to short to ground.

Isn't that also true of literal gasoline?

A 15-gallon tank of gasoline has about 1800 megajoules or 500 kWh stored, ready to combust when mixed with oxygen and heat.

You crash test the actual modules and make sure it doesn't short when encountering highway crash forces, same as you do for gasoline tanks.

1kw is enough for me for home charging, sure it takes a few days to fill up but I gain more than I lose commuting so it doesn't really matter. On road trips though I've seen 250kw

Gasoline needs a precise air/fuel ratio to ignite, it doesn't have a huge potential to want to transfer energy away to anything in proximity.

this makes no sense. If you have fast charging, why do you need a big battery?

Gasoline needs a precise air/fuel ratio to ignite

Yes, and it forms fumes in those ratios as soon as it spills. A puddle of gasoline is flammable. And once it ignites, it creates a runaway condition where the heat output of the reaction ignites the fuel around it, too.

If you have fast charging, why do you need a big battery?

Road trips. Being able to drive 4-5 hours between stops is better than being able to drive 2-3 hours, even if you don't have to stop for all that long. Small fuel tanks are annoying in gasoline powered vehicles, even if a fill up can be less than 3 minutes.

I mean, shit. 10-70% in 5 minutes? If that vehicle architecture and those chargers become even semi-ubiquitous, we are looking at a scenario where those EVs are road-trippable and there are no more excuses.

Of course that is asking a lot in the US at the moment.

(this is worthless)

Going for ICE car recharge times disregards fundamental differences in refueling and is a waste of money and unrealistic at most chargers.

that's too fast, you can barely go to the bathroom, let alone eat your lunch

15 minutes to charge is more than road-trippable. Start the charger, stretch, go to the bathroom, get a drink, reply to messages you've gotten and didn't respond to because you were driving and you are responsible, and it's been more than 15 minutes!
