Hello,
We have built a 16s9p solution that uses the 34z100 for fuel-gauging. The pack is designed around Iron Phosphate cells (please email for specifics). The device is calibrated and programmed with default values. We needed to "fool" the current parameters to be x5.
The programmed design capacity is 6000mAh, which is a factor of 5 lower than the actual capacity. We believe we have the appropriate chem ID loaded, and the 34z100 is properly calibrated (with current reduced by a factor of 5, so the sense resistance is actually 5x higher than actual). When we try to perform a learning cycle, the reported capacity never exceeds 200mAh and the resistance table will not update.
Any help (asap) would be appreciated. I would prefer to share files offline via email.
Thanks,
Joe Perino
