I'm heading on a long road trip to southern Oregon and I plan to visit a string of Superchargers in central Cali on the way. I'm trying to figure out how much dwell time to build into my schedule at each stop.
I wonder how fast they really charge in practice, and how full they really get if my 85+ is set to extended mode. The FAQ-y "3 hours of driving in 30 minutes" claim isn't what I need. 3 hours of driving at what speed, for example?
What I really need to know is how many miles are added per hour of charging, and if that is significantly different if I begin charging with the battery half full. I'm assuming charging proceeds a bit more slowly as it tapers off towards full. I'm also assuming none of these have been upgraded to 120kW yet.
And how full can I expect? I need to leave Folsom, the last Supercharger I'll see for many miles, with as much range as possible, and I'l probably arrive with 1/4-tank. Will that take an hour?
At Tejon and Harris I expect to arrive with about 1/2-tank or more. Will 30 minutes do it, or do I need to assume 45?
In all cases I want to leave full in extended mode.
