Since getting my Leaf about 2 wks ago I've been perturbed by the GoM number, which never really reflects my normal driving habits. When I hop into my Leaf in the morning after a full charge (I no longer do full charge, but I was initially), I'm excited to see GoM number showing 104 miles. Later in the day, this is replaced with saddness and disbelief that I really only got ~70 miles, due in large part to > 80% driving on highways. I thought for sure the GoM would adapt and show a more accurate number for the next day. But alas, no. It's as if the GoM always anticipates that I will only go 35 MPH in urban street driving.
Ok, no problem. I can adapt. I will block out the GoM number from my mind. I will put something in front of it and use a different system. After hours of reading thru expert posts (I'm sure I will need 1000's of more hours), I believe I've put together enough information to come up with a more accurate estimated driving range for me.
From what I've read from other more seasoned members, I'm sure there are many that can determine if my calculations are correct.
First off, since my battery hasn't had time to have any degradation, I will assume that
A1) 100% charge = 21 kwh
or,
A2) 80% charge = 17 kwh
If I'm not at exactly 100 or 80% charge, I need to determine how many kwh are remaining. I can look on the Estimated Charge Time display.
B) # of kwh used = 0.8 x (# of 120v hrs to charge)
C) Remaining kwh = A(1 or 2)-B
Now to convert that into how many miles I have left I look on the Navgation consule -> Menu -> Energy Info
For the past two weeks I've been avg 3.9 miles/kwh. But I'm going to be conservative and say 3.5 miles/kwh.
So then, my total miles left = C*3.5
When I apply this to the 'Battery Available Charge Gauge' (not to worried about Capacity Level Gauge since my batteries are relatively new), I get these new (and hopefully more accurate to my driving habit) values:
Range est @ 3.5 mile/kwh
Charge/Bars
100%/12 = ~74 miles
80%/10 = ~60 miles
75%/9 = ~55 miles
50%/6 = ~37 miles
25%/3 = ~18 miles
Am I on the right track? Any suggestions?
