So I have been seeing a constant 238 on my 85D 6,400 mile 90% charge. Yesterday I charged to 100% for a drive to Cherokee NC and waited until 45 minutes before our departure time before starting to charge it from my customary 90% charge. (That's what it estimated on our dual charger 80AMP setup). After it stayed on "4 minutes remaining" for about 7 minutes it lowered its kWh and AMP's and stayed there with just "charging" on the display. No time remaining just "charging". We averaged 280 per mile on our 230 mile trip with a comfortable 14% remaining when we arrived home.
Here he is the interesting part. We stayed at 100% for much longer than I am accustomed to beginning our drive. Last night after charging to our normal 90% during the wee hours of the morning at .0492 per kWh I awoke to see 241 as my 90% charge. Seeing as we don't do 100% charges often there does seem to be a re-balancing / configuration/ reading of the battery pack when a 100% is done after a while. Our 238 has been rock solid for over a month of watching and 241 after one 100% and used down to 14% in a single day.
Ineteresring food from thought for a Sunday morning
