i took delivery of a Model X 75D on June 24. I have noticed on about 4-6 occasions, my charging rate has reduced when the car automatically went from 40A to 30A. I noticed it happened again this week when I went to my garage and was surprised that the car was making a ton of noise while parked (sounded like external fan). Upon further inspection, I noticed the inside air conditioning had turned on and the charging rate had been reduced to 30A again. It seemed to me these things may have occurred because the car or battery may have been overheating during the charging process. Is this possible? If so, is this a safety concern?
