Hi. I recently drove from Toronto to Ottawa and back. It was 20C on the way there and pouring rain on the way back. Wh/km heading east was 168Wh/km on dry roads and west was 178 Wh/km in the rain. The prevailing winds are from the west. Ottawa and Toronto are at the same elevation. Total distance: 850.7km, Total energy: 146.9 kWh Average energy: 173 Wh/km. I drove non-stop on the way home, 398.4km and had 31 rated left. Total energy use was 71 kWh. Assuming rated is 193Wh/km, then... Here is my question: Do we know how much energy is left in reserve? 85kWh = 71kWh (used) + 5.9kWh left (31km) + reserve + battery degradation. Should I be able to calculate battery degradation or is this actually more complicated. Thanks.
