Even the upgrade of capacity is pointless if the cabling doesn't get upgraded as well. Would be like trying to pour the Thames down a 6 inch drainage pipe. So cue massive requirement for copper ...more environmentally damaging mines anyoneI'd love to know how that's achieved, short of the car being sat in the generator hall of Drax I don't see how you can get electrical power into a battery that fast.
It's not so much about how fast the battery can take charge (that can and will improve) it's how fast it can be pulled from the distribution grid and be ported into the battery.
EU wide there's going to have to be a really major upgrade of the grids and generating capacities to cope with a lot of EV's, not a terribly cheap task...
