BQ27421-G1: SOC jumps from 65% to 100%

Part Number: BQ27421-G1
Other Parts Discussed in Thread: BQSTUDIO

At the end of a charging cycle with updates every minute, the fuel gauge SOC jumped directly from 65% to 100%.

I'm trying to understand why that happened, can anyone give me some insight?

Thank you

Please see attached charging log.

  • Hi Peter,

    The gauge device has a lot of run-time information.  Without sufficient data, it is almost not possible to find the root cause. I don't use your log file for analysis.

    I would suggest you capture a bqStudio log and also share your gg file.  Thanks.
