Part Number:BQ34Z100-G1
Hello,
I'm currently trying to make a cycle learning of a Lead Acid Battery (Yuasa NP2-12), and I'm stuck in "LearnedStatus : 0x04".
In fact, I pass the "LearnedStatus : 0x05" but never in the right time :
the"LearnedStatus : 0x05" pass when the RemCap rise during the last period of "Relax" :
I'have read the datasheet of the BQ34Z100-G1, find that the gauge detect a "FULLCHARGE" condition with 3 criteria:
(a) During two consecutive periods of Current Taper Window [40sec*2], the AverageCurrent() is less than Taper
Current [100mA] AND
(b) During the same periods [80sec], the accumulated change in capacity > 0.25 mAh /Taper Current Window [80sec] so : 0.25mAh/80sec = 11,26mA AND
(c) Voltage() is > Charging Voltage [14000mA]– Charging Taper Voltage [100mV].
When this occurs, the [CHG] bit of Flags()
is cleared. Also, if the [RMFCC] bit of Pack Configuration is set, and RemainingCapacity() is set equal to
FullChargeCapacity().
I think that all the conditions are completed, maybe we should config the IC differently ?
Here the : image, log and config file of the IC :
