Hi all,
One question about SoC behavior after charging.
To start off, this is for a Ribelle, and the behavior is seen since start of ownership in June.
Typically I charge to 80% (or 90%, or other level < 100%).
If I take the bike right at the end of charging, typically the SoC reading will be on target (programmed 80/reading 80).
If there is a time before I start off (say 2_3 hours) usually the SoC has gone done a few % (say 76%).
Afterwards SoC remain reliable(it doesn't go further down) and also(let say if I stop later at 65 and run the bike again next day it is still at 65).
So basically the behavior is that usually the bike end up after charging with a SoC that is slightly below the target. Does anybody experience a similar behavior?
I have the impression it may have something to do with cell balancing as usually this effect seems less if I have just balanced the cell.
Aside of that, bike runs great so no complain, but I would just like to make sure it is standard behavior and that there is nothing 'behind the scene' going on with the pack that could harm long term reliability.

I typically charge it to 100%. Will plug in after I get home from work and it is usually done charging by 9-10 pm. Have never seen it less than 100% when I unplug in the morning. But mine will gain 1-2% while at work. If I get to work with 70% SOC when I leave for home it will be 71--72% SOC. My Eva 107 did the same thing but would gain 2-3%.

My Ribelle does the same thing...I usually charge to 80% max and by the time I go to ride it, usually a day or so later, it's down to 79%-78%. Since it's only a few percentage points I haven't stressed about it since it still provides far more road range than my 13kw EsseEsse9. My EsseEsse9 usually stays right at 80% but sometimes will also show 79%-78% by the time I ride it a day or two after charging it up.

Just remembered what is causing the drop in SOC. The Ribelle, and my Eva 107 before it would turn on very briefly as some sort of a systems check. Have been in my garage and see the lights in the tank area flicker briefly and my GPS would come on and sometimes stay on.

OK thanks for your reply.
So this seems indicate it is an OK behavior (despite the small sampling set :-) ).
Thanks all!
