Hi
We are using bq27510-G2 fuel gauge in our design. The battery we are using is 1960mAH Lithium Ion from molicell (datasheet attached). I have referred calibration procedure from the document “SLUA544”. I was able to complete the calibration procedure successfully. I have saved the data flash files and the golden files which the bqeasy has created (data flash, golden file and the log files are attached for your reference). But one thing I noticed is that the updated Ra table contains negative values. I think the impedance values should not be negative. So I would like to know why there is negative values.
Another thing I noticed is that once the golden file is updated the Bqeasy tool shows the battery is charging (without connecting the charger) but the voltage is not changing only the %SOC value is incrementing.
And what will be the best chemistry match for ICP103450CA battery from Molicell.
Regards
Ravi
