Yesterday I charged to 99% and then drove 300 miles round trip without charging. I had 5% capacity left when I parked and my "Since Last Charge" trip meter showed 66 kWh used. Since I used 94% of the battery that day that leaves me to believe that my full battery capacity is 66 kWh / (99%-5%) = 70.2 kWh, which is less than I've read it's supposed to be. Granted, my actual 100% range would have been 319 miles, which is more than rated, but I'm curious what I'm missing from the capacity equation. My trip start was at 300' of elevation and end was at 233', so 66' of net elevation changes there and I did climb and descend 7000 ft of elevation that day. The outside temperature varied between 55F and 85F throughout the day and I mostly ran the A/C in auto with a 70F set point. The car has 4000 miles on it and typically charges to 70% and discharges to 55-60% each day. I've charged it to 100% twice and supercharged 4 times from ~20% to ~70%. Any ideas? Anyone else seen similar?
