The BQ41Z50 device can permanently disable the battery pack in case of a voltage difference between the cells in a stack while active.
Status | Condition | Action |
---|---|---|
Normal | Max cell voltage1..4 < VIMA:Check Voltage OR Current() < VIMA:Check Current OR Max cell voltage1..4 – Min cell voltage1..4 < VIMA:Delta Threshold | PFAlert()[VIMA] = 0 |
Alert | Max Cell voltage ≥ VIMA:Check Voltage AND Current() > VIMA:Check Current AND Max cell voltage1..4 – Min cell voltage1..4 ≥ VIMA:Delta Threshold | PFAlert()[VIMA] = 1 |
Trip | (Max cell voltage1..4 ≥ VIMA:Check Voltage AND Current() > VIMA:Check Current AND Max cell voltage1..4 – Min cell voltage1..4 ≥ VIMA:Delta Threshold) for VIMA:Delay | PFAlert()[VIMA] = 0 PFStatus()[VIMA] = 1 |
