Part Number: BQ34Z100-G1
Other Parts Discussed in Thread: GPCCHEM

Dear sir,

For chem id calculation i tool discharge reading for different temperature on different current rate for my battery.After the process completed i updated my zip file the error will come represent in my attached image.can you please resolve my error.

Hi Arun,
Can you repond to the following:
-send File you submitted to the tool
-Number of cells in series.
-charge voltage.
-Battery data sheet.

thanks
Onyx

Thank you sir.

I found my error and i resolved it.i got one text file from your team.In that i cannot understand anything.what is my chem id like that.Can you elaborate that file.i here with attached that file.please find the attachment.

Hi Arun,

Could you please elaborate as to what was contained in the file that you cannot understand?

If the file is a report, in what ways is it not similar to the sample report found below?

A sample report can be found under Step 3 at the following page: http://www.ti.com/tool/gpcchem

Please note: The file is a zip archive and needs to be extracted before reading, however, the files contained therein are in human-readable plaintext.

Sincerely,

Bryan Kahler

Dear sir,
i uploaded my file and got the result by text file.how can i found "chem id" based on that parameter.could you please help me to find my chem id like "0803".i here with attach my result file for your clarification.

Hi Arun,

Thank you for uploading the results from the test. It appears the wrong tests are being run for this gauge. Fortunately, the fix is much easier than the steps you have been undergoing.

The bq34z100-G1 utilizes impedance track (IT) technology and requires one configuration file and only one log file to generate the ChemID. The text file and tests in your file above are for a CEDV Gauge that requires a configuration file and 6 log files to generate the ChemID.

If you are using the bq34z100-G1, or another IT gauge, please follow the steps found in this document: www.ti.com/.../slva725.pdf

That configuration file will include parameters (values will vary based upon your configuration) such as:
ProcessingType=2
NumCellSeries=1
ElapsedTimeColumn=0
VoltageColumn=1
CurrentColumn=2
TemperatureColumn=3

The data log will include a single test that follows the below steps:
1. Test is performed at room temperature. Optional: If the cell was at a different temperature before, let it
relax for 2 hr at room temperature prior to the test.
2. Charge using CC/CV charging to full, using taper current, for example C/100. Use nominal CC charge
rate and CV voltage. If another charging method is specified by the cell maker, use that method.
3. Let the battery relax for 2 hrs to reach full equilibrium open circuit voltage (OCV).
4. Discharge the battery at C/10 rate until the minimal voltage, as specified by the cell manufacturer, is
reached.
5. Let the battery relax for 5 hrs to reach full equilibrium OCV.

Please ensure the data is formatted as specified in: www.ti.com/.../slva725.pdf

When your zip file is created, please upload the zip file to the GPCCHEM tool: http://www.ti.com/tool/gpcchem

This should do it! If you have any other questions, please let me know.

Also, if you are using a CEDV gauge, please let me know which device so I may provide further assistance.

Sincerely,
Bryan Kahler
