On: BYD says new fast-charging system could be as quick as filling up a tank

I think you jumped to the wrong conclusion. Another news source suggests proper groundbreaking 10C charging:for a standard EV

> the BYD’s pile supports the 10C charging. It can charge 400 km in 5 minutes. It is two kilometers in one second! During the live test, this station reached the 1 MW level of power in 10 seconds (while charging Han L EV and Tang L EV). The car’s charging time from 7% to 50% was just 4.5 minutes.

A nitpick on the math you cite: 400km in 5 min (300 sec) is not 2 km per sec.

The bigger open question is what is the degradation penalty for 10C charging. This doesn't matter for a demonstrator but is critical for consumer use.
