For more than a year in all weather I have done this, and although the software has changed, one thing has remained consistent. I get to low battery warning as I arrive at the destination.
Last Sunday I got in the Leaf and noticed one of the capacity bars had vanished. Figured no big deal since I had made the trip last week, it would make it this week too. Strange thing is, it did it with no LBW, althugh it did go to one bar after a quick trip into the supermarket on the way.
On the way home the power available bars remained lit longer. I typically am down to two bars lately (Down to one once) when I crest the mountain coming home, and for the first time since the software upgrade I had three at the crest, and the GOM was showing double digit range (12), where it typically reads single digit (5 when I had one bar, no LBW).
I don't obsess about the battery, range, or GOM. I also don't look at the M/KWH like many here do. I drive according to time, and for this trip I allow an hour and forty five minutes. I am always a bit frugal with my energy use on these trips, as my wife is with me and she is helpful at keeping my energy use in check. I arrived on time at both ends of this Sunday drive, and with a little less concern than I had the week before, although one little light went off on the "capacity" gauge.
I am thinking that gauge may be as wonky as the GOM...
It's quite clear that whatever the loss of a capacity bar shows, it is not an accurate indicator of battery capacity
I Began to get 9 bars of charge
from my "80%" time charges this summer, and thought I might soon lose a capacity bar, but I have since returned to 10 bars of charge. From others' observations, I now believe that I probably
won't lose that 12th capacity bar till sometime next Spring or Summer. Maybe by then, we will know what it means, if Nissan doesn't find a way to make it a more accurate gauge of battery capacity before then.
Results from my actual range tests, taking into account other information reported on battery capacity, (very roughly) indicate I have probably lost Between ~5 and ~11 percent of total capacity from "new", most likely in the middle of that range, and with most of that loss having occurred in my first 6 months after my car was built, (over the Summer 2011) before I made my first range/capacity test.viewtopic.php?f=31&t=9064&start=30
Over 16 months since delivery (~18 months since manufacture) and over 13,000 miles, with "Summer" ambient temperature conditions probably somewhat higher than than average for the US LEAF fleet, my LEAF went 107.1 miles between "100% and ~ VLBW, by "semi-hypermiling" on this (relatively low speed, relatively high ascent/and descent, ~6000 ft each) route last night, despite less-than-ideal traffic and temperature conditions. viewtopic.php?f=27&t=7022&start=460http://www.mynissanleaf.com/viewtopic.php?f=27&t=7022&start=460
I also believe that with my current capacity loss, I could also still match, or come very close to, all the range projections Nissan made for my LEAF, before I leased, and later bought, my car.
