Are people really achieving this kind of range? The longest trip I've attempted is a little over 80 miles and my FFE didn't quite make it (had to stop about 5 miles short of my destination).
Does anyone else notice that for really short trips their kWh usage can be through the roof? I have about a 1.5 mile trip home from work and it's uphill slightly (we live in the foothills) but nothing crazy. According to my trip log, my average economy is sometimes 350 to 450 kWh and I'm going at best 45-50 mph tops (probably averaging 35 mph). Going to work (so going downhill) it's much lower, but still in the 150 kWh range. I admit I'm not the most efficient EV driver, but my numbers seem pretty far off from the posted chart.
I see that all the time for short trips, both ways in fact, an uphill short drive will be like 400Wh/mi and a downhill around 150Wh/mi... I ignore those. Too little power used so there's probably some rounding error in the calculation.
FORScan Lite with a cheap bluetooth OBD-II dongle is a great tool to have. I see about 28.05kWh to empty when my battery is at 100%. Doing the math, at 250Wh/mi that's 112mi to drop dead, at 200Wh/mi (no expressway and no HVAC) 140mi, and at 333Wh/mi (expressway + heater in freezing temps) 84mi range. The battery has "4 months" of age on it according to one counter I found in the BECM module, and around 9K miles already (since July).
