Reviving this ancient thread after ten years.
I started out yesterday on a full charge and HVAC OFF with RR=36.
Why, you ask?
The previous day I came home pulling a 1000+lb trailer on the highway for over 20 miles. This i-MiEV has about 50K miles on its replacement traction battery and now has a capacity of 36.8Ah. Remember, RR is based on the car's consumption for the previous 15 miles (24km).
I could post a photo of the dashboard, but I'm sure others can beat this full-charge minimum at this point in history.
