Scaling that to something the size of an EV pack will require one massive cable/connector. Call it 5kw/h in 1/60 hours, thats 3000kw, at 700v thats still roughly 4000 amps. (Please correct my head math.) Charging one car could suck up more power than an entire neighbourhood. Say four or five chargers operating at once ... every roadside charging station will need its own electrical substation.

Fjord ferries in Norway are up around that sort of charge rate, but for 30 mins instead of 5. That kind of battery charging performance is pure marketing until our local LV supply network is uplifted!
chargers of that size generally have there own internal (sometimes even shared by multiple receptacles) batteries

5 kWh * 60 = 300 kW
at 800V (typical charging voltage) that is 375A
(still huge, but an order of magnitude less)
