TIDA-010208: The reference code of battery state of charge

Hi team,

I realize that in TIDA010208, the VIT will be used to calculate RSOC of battery in MCU, may I ask do we have reference code in MCU? Thanks!

    Hi Kailun, 

    You are right about the SOC calculation in MCU, while we have no reference code since 1) we are not able to get an accurate SOC without matching with real battery; 2) charging or discharging capability can be read directly from BQ76952 which can be used to calculate rough SOC. 

    If you see the challenges of poor SOC accuracy, maybe a fuel gauge is a good option to sell. 

    Please click "This resolved my issue" if no more questions.

    Thanks.

     

    Best Regards,
