BQ4050: BQ4050's SOC Don't Change

Part Number: BQ4050
Other Parts Discussed in Thread: BQEVSW

I have set the CEDV cfg: Electronics Load as 250 (3uA) and self discharge rate as 250 (0.01%/day) because there is about 800uA load which can't reach dsg current threshold (10mA). After 5 days, the SOC hold at 100% all the time and it seems will not change. I have found that the CEDV RC decrease  about 10% ,but remaining capacity not change ,so the RSOC holds at 100%. Why the SOC don't change? Is there any other parameter need to configure? How can I do if I need to add this loss (800uA) to SOC? By the way, the SOC will change if there is real charge and discharge current.

  • hi

    Can you disable the smoothing functionality in manufacturer access to see if that makes a difference?

    pls endeavor to attach log and gg files of your next test for analysis.

    A screen shot of bqEVSW would also be needed.

    thanks
