Hello Leafers,
One way I thought might help us determine battery degradation is tracking how much energy it requires to top up the battery from 10 to 12 bars. I went through all of my tracking documents and compiled this list for my Leaf. The timer is set to 80% (83% according to carwings) and after it stops I press the timer bypass button and top up the battery. Something we do regularly in the morning just before we leave.
These readings are from the wall so topping up only takes ~3.7 kWh to 100% charge now.
April 2011: reprogramming recall P1213 done
May 2011: 5.3, 5.4, 5.3
Charger Replaced – Leaf at dealer May 25th thru June 9th
June 2011: 5.4, 4.8
July 2011: 4.8,
August 2011: No usable data, reporting from carwings and Blink 60% fail.
September 2011: 4.8, 4.1, 4.8
October 2011: No usable data, reporting from carwings and Blink 45% fail.
November 2011: No usable data, reporting from carwings 40% and Blink 70% fail.
December 2011: No usable data, leaf timer not working and/or not set.
January 2012: 4.729, 4.718
February 2012: Did not charge to 12 bars
March 2012: Did not charge to 12 bars
April 2012: 4.993, 4.487, 4.425
May 2012: 4.362, 3.276, 4.104, 4.059
June 2012: 4.252
July 2012: 3.466, 3.672
August 2012: 3.691, 3.781, 3.755, 3.870, 3.896, 3.596, 3.642
September 2012: 3.913, 3.908, 3.537, 3.964, 3.505
