Part Number:BQ40Z50-R2
Hi,
I've been cycling a two cell pack I am developing and have noticed that sometimes I get a value for Cell 1 Bal Time and sometimes it is for Cell 2 Bal Time. Which timer gets a value doesn't seem to correspond with which cell has the greater QMax at the time, but perhaps that is not unexpected. Are there some other parameters I can monitor to observe the balancing action take place, such as some of the many DOD related options?
I don't have access to the schematic for this BMS, so could it be possible that the default Balance Time per mAh values (367, 514) are causing overshoot?
Thank you,
Jeremy.
