I was doing a long distance trip from Buffalo back to New York I stopped at the supercharger in Erwin New York. Temps 83 degrees. My car is 2015 70D with 240 rated miles. Display showed 242 miles/hour charging but only 40 KW With 50 minutes to charge 62 more miles. Can 40KW charge at a rate of 240m/hr? I’ll post pic but the equation seems off
