[FAQ] What information does TI need to help with learning/accuracy/operation related questions?

Other Parts Discussed in Thread: GPCCHEM, BQSTUDIO

To most efficiently help debug State of Charge accuracy issues, problems encountered during the learning cycle process, or any other function related to the gauge like protection, there is some information we will almost always request.

  1. The GPCCHEM report and data submitted. This will let us confirm if you have uploaded the correct chemistry ID for the battery used, or if a chemistry ID with error too high (over 3% max DoD error) was used.
  2. A .gg file from before and after the learning cycle or accuracy test. This lets us compare the settings used, and check any learned data (like Qmax and the Ra table) from before the cycle started. The .gg file can be exported by opening BQStudio,, clicking "Data Memory" then clicking "export".
  3. A log of the full learning cycle or test. This lets us see what bits are set during the test. It also lets us see if the correct discharge current, rest periods, passed charge, etc was used for learning or other testing. You can start a log by opening BQStudio, on the main "Registers" page click "Start Log" and set your file name.

If this information is provided it will allow TI to give faster suggestions to resolve the issue.
