BQ34Z100-G1: Cycle Learning Failed

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 :
