BQ27510-G3: Board Calibration

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

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,

  • Hello Patrick,


    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.


    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.
