Part Number:BQ40Z50-R2
I got an issue during I was doing golden cycling for my bq40z50 based 4S16P battery pack.I cannot get it successful, QMax and Ra table cannot be updated automatically after several cycles. I was using a power supply(setting as 14.6V 20A) to charge the pack, and using an electronic load (8A) to discharge the pack.
The CHEM ID is 0x0460, it is matched with he pack battery cell. But every time, once the pack is charged to full, its OCVFR flag is set. Per bq40z50 Technical Reference document, if the bit is set, a QMax update is disqualified. I assumed this is the reason why I couldn't get the golden cycling successful.
Please help me to know why the bit is set, and how I can avoid this happening.
Thank you very much!
