On our first Supercharge at Burlington, WA, our next stop was to be a 70A 235V HPC in Ellensburg, WA. So I wanted to charge until full, OR until the charging rate fell below the rate we have seen at that HPC, which the car reports as about 50 mph or about 16 kW. But when, during the SC session, I watched the displays, both in the car and on the iOS app, I saw two divergent values that did not fit any of my prior experience. As the power ramped down, at about 97% SOC, I was seeing 95 mph on the one hand, but only 12 kW on the other. Any other observations of this? How can this be? Is it just a bug (lag) in the mph calculation? If so, it suckered me into staying maybe ten minutes too long for optimum time split between the two charge stations (SC followed by HPC). SC caveat emptor!
