Dear All, I'm the happy owner of a Tesla model S P90D Ludicrous since end of December 2015. It has now a little bit more than 12'500 km. Two days ago, I drove through Switzerland for a "long" trip and I decided to charge it at 100% the night before. The estimated km was 400 (which is correct based on the fact that I got between 363 up to 368 km when charged at 90%). As the battery capacity is 90 kWh, the estimed km is based on 225 Wh/km. When I returned back home at the end of the day, on the trip counter (dashboard --> see screenshot), it was indicated: 261.3 km, 57.6 kWh, 220 Wh/km and a remaining distance of 83 km. On the big display, it was indicated 21% remaining battery capacity. I dont understand how it's computed; from my point of view, the remaining capacity is 90-57.6=32.4kWh --> 36% of a full capacity of 90lWh. And the remaining distance (at 220Wh/km) has to be: (32.4*1000)/220 =147 km, which is making a theoritical total distance of 147+261=408 km, which seems also loigical as the mean Wh/km of my trip is 220 and less than those estimated in the begining of the day (225). Is my logic wrong? Thanks for your feedback and imputs to help me to understand that logic. Kind regards P.S. Unfortunately English isn't my mother tongue, nevertheless I hope you can understand my question.
