Just plug into a destination chargers thats listed at 16kW or higher. Whatever it pulls is your max.
Like my car has dual chargers so when I visit my mom where I installed a HPWC (destination charger) I can draw up to 80A, but I got a loaner Model 3 last week and when I plugged it in it can only draw 32A. It's amazing how effing slow that is on a new car, and my old 2014 can pull 80A.
