What would that even look like?
I think EVs are around 1 KWh for 3 miles. 225 - 350 W-H per mile is a common range from my reading. Even Jack Rickard's Electric Escalade used 'only' 777 W-H per mile.

So 320 km (from the article) is 200 miles. 200 miles / 3 miles per KW-h is 67 kw-h. 67 KW-h in 6 minutes is 670 kw-h in an hour, or a rate of 670 KW. At 375V that's 1786 amps. I think liquid cooling of the charging connector, charging cable, and battery pack are all required so that nothing melts!
