Another factor is the battery age. I think that's part of why I'm not getting as high of figures compared to some others, that or my driving is really bad for mpg and driving the car "normal" is even worse lol.
I used the auto setting for the last trip. I suspect max cold and fan speed on low would be most efficient for this car.
This car also uses a NiMh battery, which charge + discharge cycle efficiency is around 80%, Lithium Ion on the other hand is more around 95%. 15% less loss in the battery all the time probably makes quite a difference just on it's own.
Before I calculated the round trip efficiency to be somewhere around 65%, I wonder how much the battery effects that figure....
90% for generator/inverter, 95% for battery charge/discharge, 90% inverter/motor which gives a round trip efficiency figure of 77% assuming there was no improvements in the electric motor/generator setup or the inverter.
Anything electrical instantly takes about 12% less energy just because of the battery tech difference based on that math.
