Update: full charge overnight went to 265 Gid (94.3%) and took 21.7 kWh from the wall.
Thanks for the data, definitely interesting and useful.
One thing I've wondered for a while is whether or not there's any other proxies for estimating capacity loss without a GID reading.
For example, surfingslovak's range table includes L1 charging time - his chart indicates that the car should estimate 21-22 hours to 100% once you hit LBW, but I know my car was at least an hour short last time I got there.
But going down to LBW or lower is not always convenient - after all, who wants to drive around needlessly wasting energy.
So whenever I need more than 80% charge, I hit the timer-override to charge to 100% about 2 hours before I leave and record the length of time and amount of energy my Blink records before it stops charging. I typically do this about once a month, here's the data I have for the last 6 months (how long I've been recording this):
Jan 2012: 1:28 4.959 kWh
Mar 2012: 1:25 4.667 kWh
Apr 2012: 1:14 ? kWh (Blink crashed, didn't record energy)
May 2012: 1:14 4.379 kWh
Jun 2012 1:13 4.247 kWh
Jul 2012 1:07 3.959 kWh
There's a clear trend here and it certainly looks like I'm down on capacity even though not showing of the impending signs yet. For sure, some of this could simply be caused by the pack being out of balance since I don't let the car sit at 100% for any longer than I need to. Regardless, this is very easy data for Blink owners to collect, even if they normally charge to 100%. Lots of LEAF owners have Blinks out there - would be very interesting to see what someone who's down to 11 bars records as well as anyone else.
