Other Parts Discussed in Thread: BQSTUDIO
Hi,
We have already created a post for this in TI forum (please find the below link), however we are not receiving expected help. So we have created one more thread because we are working on learning cycle from more than 3 months and still we are not able to complete it.
We have procured new Panasonic battery ie NCR18650GA and we found Chem ID for this as 2107 from BQstudio Chemistry selection tab.
We are using 3S1P battery with 3450mAh capacity.
We have programmed the Chem ID using BQStudio and started learning cycle.
1)Enable IT_Enable
2)Reset
3)Discharge the battery till it reaches 9V (ie Termination voltage)
4)Relax for >5Hrs
5)Charge the battery till 12.6V (FC=1)
6)Relax for >2Hrs
We were expecting VOK bit to get clear and update status to update to 0x05, however VOK bit got cleared but Update status didn't update to 0x05.
When battery was in relax state (after full charge ie FC=1 and VOK =1) we have observed, when OCVTAKEN bit got set, FC bit became zero and Full Charge capacity value jumped from 897mAh to 900mAh and remaining capacity became 0. After some time VOK bit became zero, however update status didn't update. We are not understanding what is cause for this kind of behavior.
Since this is standard battery and we have Chem ID for this from BQStudio and we are following same steps as mentioned in the documents as well as from TI experts, still we are not able to complete the learning cycle.
We have attached .gg file and log file. Could you please go through it and let us know if we have wrongly configured any parameter and which is stopping us from completing the learning cycle.
Please help us to figure out the issue so we can complete the learning cycle at the earliest because it is gating our further implementation.

It would really help us out if you could reply at the earliest.
