BQ40Z50-R2: how can i configure SOC flag A in bqstudio

SOC flag config A and SOC flag config B determines how the bits TC, TD, FC, FD are affected by SOC or voltage, typically, you can use the default value.

if you have any specific requirements, please let me know which bits are in care so that I can look to further explanation for you, the most straight forward explain is in the TRM.

The Item with the caption of Relative State of Charge is the SOC you are looking for. Please let me know I have answered your question

Steven Yao Thanks for your response sir. In register section i successfully read voltage,current and temperature but SOC  indicates 0%.

Hi

    You should first identify the chemistry ID of you battery, then program the chemical ID to the target device.

    Then send enable IT to have the GAUGE_EN bit set

    Then do the learning cycle according the document of ""
