I mean, this is still more or less what the fast charging standards do; they're pouring more power into it faster with higher bandwidth cables and sectioned charging.

The level 3 fast charger is basically the equivalent of 4 power cords from your wall. Also, adding more and more hardware and things for it will effectively make the electronics more complicated, which means more expensive, difficult to manufacture and repair

But also, as you scale this up more and more you'll start running into issues that make it difficult to start pulling more power; energy from the grid isn't infinite
