Other Parts Discussed in Thread: BQSTUDIO
I have two eval boards with identical GG files loaded, each with cells from the same manufacturer and lot.
On one of them, if I apply a charge voltage and meet the conditions for VCT as specified in the TRM, the Battery Status bits that are supposed to trip do trip.
On the other, achieving the same conditions, the TC bit will not trip and the battery keeps charging and won't update RSOC.
Both packs report charge currents under the taper current limit.
The only difference between the two is that the first pack's minimum cell voltage exceeds the charge termination voltage as well as its maximum cell voltage, while the second pack only has the maximum cell voltage above the threshold.
The TRM states that the maximum cell voltage is the one that matters.
Why is charge not terminating for the second pack?
