And to add to these questions - what are the consequences for increasing charging rates? Tesla has made some public statements regarding fast(er) charging (specifically targeting the 350kW Ionity chargers) to the effect that pushing that much power will degrade the batteries far faster for little gain.
Edit:
Our technology is able to decrease the irreversible chemical reactions that happen during charging, so that the same batteries can be charged fast without compromising cycle life.
This seems to imply it's doing something to the battery chemistry? Maybe a brief pulse of high-rate discharge every now and then to help balance things out?

That's usually within the domain of the battery management system. There's not much the charger itself can do (there is intelligent communication between EV and charging equipment, but not as granular as the view the BMS has).
