BTW, how did you find out that they ran the test at 100%? Was there a report that they provided that showed the SOC or the cell voltage?
I did get a copy of the report.
Along the top of the report is has some values:
Recording Time: 10 sec
Sampling Rate: 10 msec
Trigger Rate: Pre 80% / Post 20%
Cell Voltage Loss Judgement Value: 3694.677083 mv
"No Module Requires Replacement"
What leads me to believe the test was dome at 100% Charge is:
8 pages lists all 96 cell pairs, and they are all at 4.118 - 4.131 (13mv) - thats the same as I show in LeafSpy at 100% charge
Total Battery Voltage: 395.80v - thats the same voltage at 100% shown by LeafSpy
However, I was keeping an eye on the battery via car wings - checking it a few time throughout each day they had the car
The day I dropped it off (to be there for a week or so - dealer is about 40 miles away) I got a text that evening that the car stopped charging - and it was at 100%. So it will sit there for a week at 100% - geeez!
Anyway, two days later I noticed the charge went down to 30% or so. Then was charged again to 100%.
After checking the milage, car was not driven. Perhaps that was the test??
The voltages in the report look very much like a 100% charge.
I understand the voltage requirement for the test is 3.712v
When I did a Range Test last month, I took battery down to 2.15% (LeafSpy) and had 5 GIDs, .39kwh, cells were 2.995/3.062/3.142 (147mv) 294.02 Volts
No cells were shunting, they were all blue. The cells appeared to be in TWO banks - divided about 50/50 the averages of one bank a little lower than the other.
LeafSpy reported "All Cells OK"
My Driving range is good, and predictable - so I believe the pack is good,in fact, getting better the more I use it
I was not able to talk to anyone about the test.
There is ONE person in Service that seems to have some knowledge of Leaf Battery and is friendly and entertains my questions.
Everyone else gets upset and irritated when I ask any questions at all, other then "where is the bathroom".
I called 2 times & specifically requested the test results be attached to my repair order AND my keys so I can get them when I pick up the car to discuss as I expected that I would not get the results when I showed up because they "couldn't find them" - thats why I called TWICE to make sure, plus, I live 38 miles from Dealer.
As I predicted, the results were not with my paperwork. I had to call the next day, and they mailed the results out to me. So, I was not able to review them and speak to a Leaf technician about the results... likely that would not have revealed anything anyways, but still... Frustrating!
