I have a question about fuel gauges, in particular bq2060a. I am using a bq2060a interfacing with OMAP3 using HDQ interface. After a few charge and discharge cycles I see a divergence in measured voltage vs. measured charge. For example, I read 7.6 volts from fuel gauge while remaining capacity shows %1. The new battery typically maps such voltage with around %30 of remaining capacity. Is this normal? What is the best way to make sense of fuel gauge? It seems that the chip gets out of calibration and cannot converge to a proper value anymore.
Please let me know if you need more info.
