The highest charging power I have seen through the adapter is 180 kW. I think the charger was rated at 300 kW, and the battery had not been preheated at the time.
My estimate is that my adapter may allow a peak of around 200 kW, but that is not a confirmed technical limit — I have personally observed 180 kW. I cannot give a measured 20–80% charging time for each of the charger ratings listed.
There is detailed data from using the car in the diary: Nerd Stats and Charging.
