BQ27Z746：SOC 不能更新

rong hero
Prodigy 140 points
Part Number: BQ27Z746

Tool/software:

您好，我们用到BQ27Z746在设计一款产品过程中，发现一颗电池放电到了3V以后，静止的时间超过5个小时，SOC仍然显示是100%，然后再充电到截止电压4.4V，这过程中，SOC一直是100%也没有更新，能告诉我是什么原因导致SOC一直不更新吗

    Hello Rong,

    Can you send a log file showing the behavior you are describing? Can you also send the gg file from the gauge?

    Regards,

    Adrian

    Hello,

    I will also need to see a log file.

    To upload a file, press the "insert", then press "Image/video/file"

    From there you can upload a file from your computer.

    Regards,

    Adrian
