They must have been done charging. If they were charging, the max available to you would have been 100kW (277V*40A*3 phases*3 banks), since (at least) one 33kW bank would be dedicated to the other car (27V*40A*3 phases*1 bank)Stall 2B worked fine. I got 110 kW from it while someone else was using 2A at the same time.
