Great news! Hope it’s not too hard to port this technology to the existing infrastructure.
The biggest chargers I commonly see are 350kW. That's about 15 miles per minute. The NACS connector doesn't have a max amp spec, but at 800v/650A that's just over 500kW. CCS has a similar limit. The cables also get ridiculous above 500kW, but higher system voltages can reduce that.
Of course, they're working on a 3.75 megawatt connector
3,000 amps at 1,250 volts
That is in insane number to wrap my head around
It's difficult on the back end of the charger as well.
A shopping centre or rest stop can't just spring for a few high capacity chargers for the car park. A single megawatt charger is 50 houses worth of consumption, so they now need a substation upgrade to provide what is basically a whole neighbourhood-equivalent of power.
