Doesn't this mean you believe that your battery may be accepting nearly the same kWh from the wall now, at both 80% and 100%, as it was when you began tracking it, on 10/01/2011?
...Vegastar summed it up pretty well. It looks like I am down 6-8% from when I started tracking last October but I was already down 10-12% by then (why I bought a gid-o-meter and started logging).
When you say, “down 6-8%”, I assume you are referring to the three charge sessions that you posted on P.1 of this thread?
I have been looking at your reports, in their entity.https://docs.google.com/spreadsheet/ccc ... li=1#gid=1
Maybe I am reading your entries incorrectly. Do columns P and Q. “0 to 80 wall”, and “0 to 100 wall” not represent your kWh use from the wall, for 80% and 100% charges respectively? For example, the earliest entries in these columns for October 2011 are 16.41 and 20.15, and your most recent are 16.90 and 21.20 respectively. Column Q has no entry for the 11/21/11 charge session you report on P.1.
Are P and Q reported from a meter, or calculated by other means?
As I interpreted the data in those columns, as plotted on your “LEAF Battery Capacity” chart, I thought I was seeing an account of relatively stable capacity, with no clear indication of capacity reduction over the 10/1/11 to 8/11/12 time period.
I understand charging efficiency “from the wall” will vary, but I would not think it would distort the trend line so significantly, in this sample.
What am I getting wrong?
As to prior to October 2011, do you now believe you had 10-12% greater (new LEAF “normal”) capacity on delivery, and lost that entire amount by October?
IIRC, at one point you suspected that you'd had reduced capacity in your LEAF, from the time of delivery.
