I have a 2016 Leaf with the 30 kwhr battery and about 20K miles on it. The range is below expectations and the displayed state of charge drops in a very non-linear fashion.
I recently did a range test and got 69 miles before the range stopped displaying. The efficiency during this test was 4.2 miles/kwhr; temperatures were approximately 50 F.
The state of charge drops very quickly when between 25% and 75% charge - between 2 and 2.5% per mile. The displayed range also drops precipitously when the battery is in this range. Outside of this range (i.e. between 0-25% and 75-100%) the state of charge drops at approximately 1% per mile.
The Nissan dealer did a battery check and hard shut down recently. The battery tested "excellent" in all the categories. The low range and non-linear loss of charge continue. The dealer suggested the range I am getting is not unusual. I don't believe that is accurate.
Any suggestions on what may be causing this and how to resolve it? Is this out of the ordinary performance?
