I don't know if this is usual in the other i-MiEVs. Mine does it often. Swiching off charge before full, but showing 100% SoC. But if I try to charge it again, then it corrects the SoC and accepts the new charge.

I've noticed Koorz re-adjusting SoC once or twice when driving a short distance (about 5 miles), parking, then going again. Maybe it's a sign of internal resistance throwing off the voltage reference of the charge level? Or just that the car needs a few calibration charges to line up the charge profile?

Bear has a newer pack with the improved cells, and I've yet to notice SoC changing while parked (outside of a .5-1% change overnight after fully charging).

"I've noticed Koorz re-adjusting SoC once or twice when driving a short distance (about 5 miles), parking, then going again." I see it too. Sometimes 10% SoC goes away after re-adjusting SoC twice, when parked between 95% to 80%. But then it recovers the two bars lost latter (one by one), when parked at 50% SoC. Only lose or recover after parked for some time.
