BQ27411-G1: bq27411-G1

just upload your file as a zip without password.

please read the instructions on the gpcchem page. please remove all the unnecessary rows in the csv file.

The instructions are very clear here,

The GPC tool requires a single .zip file containing one configuration file, and one data file, as input.
The name of the .zip file is not important. The .zip file must contain these files:
• config.txt
• roomtemp_rel_dis_rel.csv

Configuration File (1 Each)
The configuration file is a text file named config.txt and is an ASCII text dictionary that contains this
information:
• ProcessingType = 2 Determines the type of tool used. Value must be 2 for chemistry ID selection tool
• NumCellSeries = Number series cells
• VoltageColumn = Zero-based column number for the voltage data in your data logs
• CurrentColumn = Zero-based column number for the existing data in your data logs
• TemperatureColumn = Zero-based column number for the temperature data in your data logs
• ElapsedTimeColumn = Zero-based column number for the elapsed time data in your data logs
Typical settings are:
ProcessingType = 2
NumCellSeries = 1
ElapsedTimeColumn=0
VoltageColumn = 1
CurrentColumn = 2
TemperatureColumn = 3

Data Log File
Data logging stores data in a file that contains these columns in a comma-separated (CSV), tabseparated,
or space-separated format:
• Time (in seconds elapsed)
• Voltage (in millivolts)
• Current (in milliamps where discharge current is negative)
• Cell temperature (measured by a thermistor attached to the surface of the cell, in degrees Celsius).
One decimal place is acceptable.
If the initial data format is not one of the supported formats (for example Microsoft®Excel®), save the data
file as a .csv file. Text that is not included in the data columns (such as the log file header generated by
bqStudio or EV Software) and empty lines should be removed from the file prior to submission. One row of
column names can remain, (the tool will skip it), as long as it has just one name per column.
An easy recording method utilizes TI's bqStudio software utility called GPC Packager that reads data
directly from a TI fuel-gauge.
The columns can be in any order since the column positions are defined in the config.txt file. The log file
can have some other data columns that are not used in this tool (removing them is not required) if the size
of the .zip file prepared for submission does not exceed 2 MB. Note that since the file is compressed, the
user can decrease the size by utilizing different compression settings in the archiver program.
The sampling interval is from 5 to 100 s.
The initial charging portion is not required. The charging must be performed shortly before the relaxation
period. Relaxation data is required before and after the discharge.
The precision of the measurements is important. In particular, current measurement must be better than
0.1% of range accuracy, and 1 mV voltage measurement at room temperature. 16-bit ADC is
recommended.
Rename the data log as: roomtemp_rel_dis_rel.csv prior to submission of the file regardless of actual
text format.

In your dsg log make sure that you remvoe all the other columns that are not in this list. Your dsg current should be negative. Start with at least one to 10 rows of zero current.

It should look something like this,

ElapsedTime Temperature Voltage AvgCurrent
4 23.65 4087 -1300
8 23.65 4087 -1300
12 23.75 4086 -1300
16 23.85 4085 -1300
20 23.85 4084 -1299
24 23.95 4083 -1299
28 23.95 4083 -1299
32 24.05 4081 -1299
36 24.05 4081 -1298
40 24.05 4080 -1298
44 24.05 4080 -1298
48 24.05 4080 -1298
52 24.15 4078 -1298
56 24.15 4078 -1298
60 24.25 4077 -1297
64 24.25 4077 -1297

Not what you have in there.

You can't update chemistry on the bq27411, the gauge is a ROM gauge.

You can only do that by choosing a different gauge.
