They are accurate. The guessometer will only settle on a realistic number if you have driven in a linear and predictable fashion for about 10 miles. If you are willing to give it a shot, try the following method next time you are driving a longer distance (15+ miles):
- reset the in-dash MPK gauge
- reset your trip odometer
- wait for the MPK readout to settle (~ 3 or 4 miles)
- multiply the MPK readout by 1.5kWh (= miles per bar)
- watch your bars go down
- multiply bars lost with mileage estimate per bar (= total miles per trip)
This method is usually within 2-3 miles of the actual and is quite reliable.
To get the total range at the outset of the trip, multiply the MPK readout by 21kWh (total available battery capacity) if charged to full and by 17kWh if charged to 80%. Keep in mind however, that the last remaining 3kWh, or the reserve, will be accompanied with multiple low battery charge warnings and the last 10-15 miles of your journey can be a bit nerve-wracking because of that. The method itself is quite accurate however.
Tony Williams has prepared a very nice chart
for other owners to use and once the SOC meter gets more sophisticated, we should be able to program our own guessometer, which will hopefully be a little less crazy than Nissan's.
