I have a model S 60 that has approximately doubled the amount of time it takes to supercharger on road trips, in the past year. I took it to the service center and they said “vehicle is supercharging as designed”. They refer to a supercharging session, at a 120kW supercharger, at a station that had more empty stalls than full ones. They say “Found vehicle began super charging at 12:30 at 24% and completion at 2:10 at 97%.” My question is; Does this sound right? Should it take a MS60 1 hour and 40 minutes to go from 24% to 97%?
