I took a two-day trip from Salt Lake City to Seattle with the family over this past weekend. Temperatures were consistently over 100F. My Model X 75D was the only car at most of the superchargers, but I was only getting somewhere around 50kW at every station. This includes Salt Lake City, Tremonton, Twin Falls, Boise, Baker City, Kennewick, and Ellensburg. Sometimes it would start out at 90kW and pretty quickly drop to 50kW (or lower). All SC stations were effected to some degree, some more than others. Kennewick only gave me 42kW. When there was a second car at the SC, the drivers complained about their charge rates too. What was supposed to be just a 25 minute stop turned into an agonizing hour every time, adding nearly 2 unexpected hours each day to our travel time.
At Twin Falls I called Tesla tech support to ask what was up. They said the car was functioning fine and that the SC was in some sort of "variable charge" state. Seems all the SC stations where temperatures were above 100F were in this "variable charge" state.
On the way out to SLC, Superior completely crapped out in the middle of the charge. Went from pumping 90kW to falling to 0, with a warning message on my console about how supercharging was not available and to try again later. Unplugging and plugging back in resulted in the same message. Fortunately that was just a bathroom break, and we were able to make it to Missoula with the charge we had at that point.
Is my experience typical for hot weather road trips? If I have to add two hours each day on top of the normal SC time, I don't think I'll try taking the Tesla on the next summer road trip.
