For some value of "correct" but not others. For EV's, most of the time, the "correct" thing to do is to plug it in overnight, and let the software do the rest to optimise charging. Which might look something like:
Charging to start at midnight (or whenever the cheap rate starts) and complete by 7am (or usual wakeup time) and minimise wear by charging below a fastest rate, and take the battery level from where it is now (e.g. 50%) to the configured stopping point (e.g. 80%)
This is clearly different from "charge as fast as possible and be done in 20 minutes". Although that is occasionally the requirement. But not most of the time.
I miswrote. I meant that it's not the battery being the bottleneck, but rather something else - the charger, the cooling, the grid, the
user/app setting a non-maximum power etc.
Agreed, though the other point is that the larger charging system (battery, charger, grid etc) being the bottleneck in need of optimisation is not typical. It happens, but not every time. For overnight charging, you want L2 and usually the rest doesn't matter so much.
