Part Number: BQ27510
Hello,
I'm using BQ Studio for the first time with my 1300mAh single LiPo cell. I've tried to do a learning cycle twice now but to no avail. I'm following the instructions in SLUA902 page 7. My logging file is attached. A couple questions and comments:
1. For each of my two attempts, I did not allow it to relax for >5 hours before the charge cycle. Is this 100% required? My PCM opens at 3.0V, and each time I was worried the PCM would open, hence cutting off power to the fuel gauge. Does it matter if I discharge until the PCM opens? Or should this be avoided?
2. Do I program a new (guessed) ChemID before the learning cycle? Or just stick with the default? I've updated all the data flash values as appropriate.
3. On my most recent learning cycle Qmax did not update and update status did not change to 01 after 2 hours of relaxation after a full charge. Could this have to do with not giving the battery enough time to relax at full discharge previously? It got probably 1 hour of relaxation, not 5.
Any advice would be appreciated on how to best get over this hurdle. Thanks. (Please visit the site to view this file)
