BQ27510-G3: Board Calibration

Part Number: BQ27510-G3
Other Parts Discussed in Thread: BQSTUDIO

Hi
My name is Patrick Mitchell, and I work for Syntronic Canada. I have a customer that is designing a device, and they've contracted us to work on their gas gauge circuit. I am not ready to begin testing, so I'm not in a huge hurry, but I've run into one large obstacle that I can't seem to find my way around. When the circuit board is ready, I've asked for 20 boards for an averaged calibration (CC/board offset, temperature current and voltage), as I was told that the process was to run the BQStudio calibration across 20 boards, and average the returned values for a gold file. I see this process talked about in the BQEasy document, but absolutely nothing in any BQstudio document that I've come across. The process of calibration is relatively straight forward, but I don't understand how to do the following:

1) Run all calibrations across 20 boards and average the results to be saved in the gold file.

2) How do I take that returned data and fit in the cell characterization data after the learning cycles have been completed?

Thank you sincerely for your time. I sincerely appreciate it.
Warm regards,
Pat Mitchell

  • Hello Patrick,

    1:

    Are you wondering what data needs to be averaged? You should be able to take the calibration data (calibration under data memory tab) and average it all.

    2:

    You would upload the averaged calibration data to a gauge that has completed the learning cycle, then setup whatever configurations you want and export the .srec, that would be your golden file.

    Sincerely,

    Wyatt Keller
