The really high voltage fast chargers as far as I understand them connect directly to the battery bypassing the cars battery charger to directly charge the battery not sure how much communication there is on those channels though.

You're probably thinking about the on-board inverter, it's often referred to as a battery charger. The battery management system is entirely within the car, and the car will tell what voltage and amperage to deliver to it.

The design of CCS2 is actually quite nice. There are pins for singalling that, if broken, will immediately shut down power delivery. This means that you can just pull the cable out safely, without risking arcing or electrocuting yourself.

My understanding was it also bypassed the BMS but I may have confused what they were saying it's been a minute.
