I am using a bq30z554-R1 and have issues with the CycleCount() continuously incrementing, usually about 3cycles per second until it maxes out at FFFF. In Settings/Configuration/Gauging_Configuration, I have CCT set to 1, so the CycleCount increments at 90% of the FullChargeCapacity(). Now when I read the FullChargeCapacity, I see 1026 (CapM=1 so units are 10 mWhrs). Oh, and the actual and reported Current is 0 (pack is at Rest and Current=0).
Has anyone else seen this behavior before? Is there something else in the gauge that controls the CycleCount()? I calibrated the voltage and current sense.
Here is the .gg file with a .txt extension:
