EV Charging, how fast can you get?

Foffer
I have just seen this article about a 1.2MW EV charging point:

https://www.express.co.uk/life-style/cars/1123418/electric-car-charging-300-miles-range-15-minutes


How do you get this sort of power down a cable that you could easily pick up and plug in?  Where does the power come from?  What would this sort of charging rate do to the battery?  I hope all this stuff is properly shielded or I could see a few watches and phones suffering, bearing in mind that these items could easily be touching the cable.

    1.2 Mw is easily available at 33 Kv and just about doable at 11 Kv.

    Presuming that we are sticking with LV for the actual charging connection and flexible thereto, then the currents are substantial but not un-manageable. A few hundred amps at 990 volts.

    I don't foresee such fast chargers being hugely popular due to the costs. A lot of EV charging will probably be done overnight whilst the owner sleeps, or during the day whilst the owner is at work. A 7 KW domestic charger will fully charge most batteries overnight. A 22 KW charger at a workplace would fully charge  most batteries during a working day.

    The main demand for very fast charging seems likely to be at motorway filling stations. 10 minutes of very fast charging whilst the owner uses the toilet and purchases a cup of coffee would give a significant extra mileage. Many EV batteries can achieve a 200 mile range, a 50% increase whilst making a brief stop would give 300 miles, as far as many people wish to drive in a single day.

    Those willing to drive greater distances will need either a higher specification EV with a larger battery, or will need to make multiple stops.
