BQ78350-R1: Issues using Gauging Parameter Calculator

Part Number: BQ78350-R1
Other Parts Discussed in Thread: BQSTUDIO

Team,

I have a customer designing a new 3.5AHr Li cell product with BQ78350-R1 via Gauging Parameter Calculator, and the file is not successfully compiling. They have had this issue in the past, and on these occasions we recommended slight changes to the config file to get this to build correctly. Could a member of the team reach out to me to see about giving them a hand here? I have their data, but don't wish to share it here.

    Please carefully follow the instructions and copy the format in the example submission files as the calculator is very particular about the details. The GPCPackager plugin in bqStudio can also help.

    In this case the issue is caused by added spaces in each row.
    There should be no spaces, like this:
    NumCellSeries=7
    NumCellParallel=7
    CellTermV=18
    ChemType=2
    VoltageHeader=1
    CurrentHeader=2
    TemperatureHeader=3
    ElapsedTime=0
    FitMaxSOC%=12
    FitMinSOC%=6
    EDVTC=7

    Also, a lot of names are wrong. The correct names are:
    NumCellSeries=1
    CellTermV=3000
    ChemType=1
    VoltageColumn=7
    CurrentColumn=13
    TemperatureColumn=6
    ElapsedTimeColumn=2
    FitMaxSOC%=12
    FitMinSOC%=6
    LearnSOC%=7

    Was the file created by GPCPackager or manually?
