I disconnected the 12 v. battery on my i-MiEV before storing it 6 months ago. The charge level when I stored it was ~40%. I was pleasantly surprised that the 12 v. battery's voltage was 12.3 after sitting for 6 months, so I have just reconnected it.
When I started the car, the battery pack's charge level gauge was initially at 0% but then increased to ~40% at the rate of ~1 bar/second. How accurate do you think this is? I expected the battery pack's charge level to drop over 6 months, but the gauge suggests that it hasn't. How does the battery management system determine the battery pack's charge level after the 12 v. power has been cut?
I still can't charge my car in its parking space, so I need to drive to a public charging station. I'm a little concerned that while driving, the battery management system might determine that the actual charge level is lower than indicated which would then cause a downward recalibration of the charge level gauge. I don't want to suddenly find that I don't have sufficient remaining power to reach a charging station.
Thanks for any insight that you have!
