I know there have been other posts on this subject, but my problem seems to be slightly different. My battery is not updating Qmax or Updated Status on either charge or discharge, but all the relevant flags seem ok. e.g. for a charge cycle:
1. I turn on IT Enable when pack is fully discharged and has rested for a while. RUP_DIS goes off and VOK goes on (QEN already on).
2. Then I charge until FC flag is set. Then leave battery to relax.
3. After about 20 minutes, VOK goes off, OCVTaken goes on. FC and QEN are still on, RUP_DIS is off. But Qmax, UpdateStatus and Ra table are unchanged.
4. After waiting 4 hours, there is no change. Qmax, UpdateStatus and Ra table are unchanged.
Any ideas?
The same happens on discharge - the fuel gauge, SOC1 and SOCF are working fine. VOK is set during discharge and clears during rest period. OCVTaken is set during rest period. But Qmax, UpdateStatus and Ra table do not get updated.
At no time has the charge or discharge cycle been disrupted and logging has continued througout.
Any help would be greatly appreciated.
