Nissan LEAF Battery Charging Difference Explained
Andrew Chiang replies and says, "yes," it is normal, but also writes that it is worthless. He points out to a discussion at MyNissanLeaf.com and continues: "If you have 2013+ LeAF, you are FAR better off depending on the % SoC (State of Charge) display. I just "love" it when my GOM starts off at 80 miles and when I drive 8 miles, it goes up to 88.... Or, if I go up a steep hill (e.g. highway 17), GOM drops by 40 miles after giong only 10 miles. As I said, worthless."
Ed Mellinger explains that battery charging differences depend on owner's previous driving pattern. It "depends how you were driving before you stopped to plug in. I assume you're looking at the guess-o-meter, the affectionate name for the mileage estimate that's displayed on the dash as part of the "fuel gauge". It looks at your recent driving and resultant energy economy, and predicts how far you can go with available charge if you keep driving the same way. Fast on the freeway, slow on a secondary road, stop-and-go traffic, all have very different energy efficiency and thus different mileage estimates. Switching on the heater, A/C, or defrost will also knock a bit off the 'guessed' range," writes Ed.
Amanda Butterfield, who originaly asked the question, clarified that her's is the 2013 model. She charged it the night before from practicality dead (got the find a charger message), and it only went to 77 miles at 100%. "I only drive it around town so far, and just two trips about 35 miles one way. I'm using the home charger with thoughts of possibly getting a home L2 charger," Butterfield says.
"As for 'practically dead,' there are 3 warnings: LBW, VLBW (Very Low Battery Warning) then turtle, replies back Chiang. "It's been stated that (when the car is new), LBW sounds at ~17-18% SoC, VLBW at about 7-8% and turtle at 1-2%. Those percentages may rise as the battery degrades. The LBW and VLBW values are about right."
Sanjay Saigal replies to the original question. "Your driving style is the single largest determinant of range (other than battery condition). Aero-mods are not particularly common, perhaps because the Leaf has been designed ab initio as an EV in which range maximization is primary and also because of the prevalence of leasing."
Marc Fontana asks questions all Nissan LEAF owners should ask themselves and suggests a solution. "How many miles do you have on your 2013 LEAF? I have a 2011 LEAF and charge mostly to 80%, unless I need more range that day, then I plug it 1 hour before I leave to get to 100%. 77 miles seems pretty low for a 100% charge unless your driving just prior to charging was at higher speeds, or your battery has lost some capacity. How many miles on the odometer? How many battery capacity bars do you have? Have someone get a reading of the battery health with an app like LEAF Spy."
