I was supercharging at a Service Center late last night. It was about 90 out. It started off great, pulling around 290 Amps, 400 volts. After about 20 minutes (when SOC was like 30-40%) the amps dropped off to 74 (volts remained around 400) and would not exceed 74 for the rest of the charging session. Took forever to charge the rest of the way! The other stalls were empty so it wasn't a case of a paired supercharger. Very odd. Did my car or the supercharger equipment malfunction? I've used this stall in the past and no issues. Doubt it's relevant, but I'll also note I got a software update available around the time the amps dropped off (2.28.19 --> 2.28.60). I didn't install it until after I got home after supercharging. Any ideas?
