I am using a bq27425 to gauge a Lithium Ion rechargeable battery that has a nominal capacity of 400mAh and a discharge end voltage of 2.1V.
I set those values into the GasGaugingState table. But, I read bogus values for the Avg Current and Avg Power. Worst of all, I get 0 for the StateOfCharge. It never goes above 0.
It seems that the chip is not measuring the Charge (Q) across the sense resistor. What could cause this failure?
