Yes definitely a game changer in the UK..
"320km on 6-minute, ultra-rapid recharge, triple that possible with current lithium-ion battery."
So battery capacity approx 81KWH - approx.. so to charge it requires a 810KWH connection (6mins) which at 240 V =approx 300amps .
The mains cables in the substations will melt.. .No UK house could charge that - the consumer unit would stop at 100Amps..
20 years to update the infrastructure.
Actually at 240 volts 1 kw = 4 amps, so 810KW x 4 = 3,240 amps for 6 minutes - that is some cable you will need, mind you we will have superconductors at room temperature by then so cable will only be 1mm diameter (all aboard the 'Tomorrows World' bus LOL).
Just a guess but at that charging rate I guess the battery may get hot (Boeing Dreamliner fires a few years ago) so may need to add a cooling system to battery - further increasing weight of vehicle.
When I was in maintenance we did predictive fault finding, using experience to highlight possible weak spots in equipment, once you have found the problem the solution can be pretty straightforward. I can see many weak spots in EV roll-out the way it is being done (by Hype and subsidies) when lack of standards and infrastructure are being ignored by clueless governments who are being advised by people with very firmly vested interests (in their own profits, not the future of the planet).
