"So yes I had gained 1/4 of a bar by just by letting the car rest bringing me back to 2 bars." Maybe it was 4/4 bar, and the car would show two bars as well.
My battery is not as new. Most of the times it charge to 95,5% of SoC, but sometimes it charges to 99%, 99,5% (usually does it when it is more discharged, i think). Gives always the 16 bars (one day it will not do it anymore, i think, but that will happen in... 2015?). Balances well, giving a difference of 0,01 V at full charge, no difference at 70% charge. Usually, under 20%, it starts not to balance anymore. But most of the times, if i want (i think when it takes 5% of SoC in the middle of the day, as i lunch), it runs into turtle like it was new (less then 9,5% of SoC).
Yesterday it went to 21%, 2 bars left. By night i made a full charge, it gave me 97,5%. 13,1 kW.h used. Should be 14,5 kW.h so 10% less. But as i showed before we can not rely on much in the SoC values (sometimes it adds 5%, sometimes takes). Maybe yesterday the real SoC was a little more then 21%.
I see power in the i-MiEV battery as a blanket. When the battery is new it covers the head and the feet. Has time passes the blanket shrinks, so sometimes it will not cover the head, sometimes it will not cover the feet. When, after giving me 5% more after a cold night, it reaches 100%, the 16 bar is 8% of SoC and i can do 14 miles with it. But if i don't stop for a while, the car will simply stop at 14,5% of SoC.
