Related to the original question, we too have an issue with the RSOC stuck at 100% during discharge; see discharge graph below based on 11 battery packs tested:
Sample Interval: 10 seconds each data point
The percentage on the right hand side indicates the RSOC error in percent ranging from 8% to 30%.
Pack 764, indicated in grey, remained at 100% RSOC the longest during the discharge, and correspondingly, remained at 99% RSOC the longest on the charge cycle preceding this discharge.
The .gg file is configured with sync (CSYNC) and the RSOCL is enabled, which are the configuration settings TI recommends to improve/solve this issue.
Based on the reviewed TI Forum comments, we believe the concern is that although the RSOC is locked at 99% due to RSOCL, internally the RSOC is 100% and if the FC Set % = 100, then the gauge will continue to record Passed Charge because internally FC is set. If the Passed Charge exceeds the Remaining Capacity, the gauge will not decrement the Remaining Capacity until the excess Passed Charge has been used up.
The question is, should the FC Set % be set to 100%? Or should the FC Set % be set to -1, which will disable the function of setting FC in Battery Status if RSOC is equal to or above the FC Set %.
It may be best to have direct contact with us as we have a lot of data to share on this critical issue. Please advise.
