Thanks. You might want to edit your initial post to reflect that because I was scratching my head for 6 pages wondering what kind of driving patterns we were talking about
I blogged about experimenting with the battery numbers and explained what I did and it at first it seemed as if exercising the battery made it stronger because all I was doing is driving to near its capacity daily and simply recharging it for the next day.
But any time I skipped a day of charging or simply did not drive much, the numbers nose-dived so I then thought that maybe the BMS was recognizing driving patterns and merely allowed more access to the pack to accommodate.
but I think the real mechanism that is going on is simply a better balanced pack. For a few years, I took a delta of 50 mV to be pretty good and it wasn't until someone mentioned it that I started to monitor the deltas at various SOCs and found that my higher numbers very closely correlated to the balance of the pack in the lower ranges. Although top end balancing is important, the real differences in the cells begin to widen as the SOC drops. It was pretty normal for me to see deltas os 300-400 mV when SOC was low especially at or near VLB.
But when my battery stats were artificially raised to over 95% of new batt stats, the delta even at low SOCs were cut rather dramatically
