I’ve noticed that I have not heard the fans on my model S churning away during superchargering. This struck me as odd given how hot it’s been during the day lately and how when I plug in I hear other Tesla fans blasting the battery with cool air. Should I be worried? I queried it with Tesla who looked at the data logs and said the car was cooling the battery sufficiently, despite plugging in at 28 degrees and after an hour of hard driving. My big concern is there is battery degradation and Tesla don’t shell out the £20k or whatever to replace the pack.
