BQ27541: Conditions for acquiring log data with GPCCHEM tool

Hello Koki,

If you have not already done so, first update the chemistry database in bqStudio https://www.ti.com/tool/GASGAUGECHEM-SW

This will have the latest updates.

Not sure what the question is: are you asking for the procedure to generate logs for submission to GPCCHEM tool?

Hi, Shirish

I want to know the flow for getting a Chemistry ID. Are the steps 1 to 4 below correct?

--------------------------

1. Update Chemistry Database in BQ STUDIO. (What you answered)

2. Check if there is a similar Chemistry ID in BQSTUDIO.

3. If no model in the table matches the cell in Step 2, create a log based on the GPCCHEM tool and obtain a GPCCHEM report.Running the GPCCHEM test is the best method to determine a good chemistry ID for the gas gauge.

4.If no appropriate ID exists in step 3, post the GPCCHEM log and my gauge setup to E2E.

Yes. In addition, do you have any information about the conditions (charge and discharge conditions, etc.) for acquiring log data with the GPCCHEM tool in step 3?

Thanks,

Hi, Shirish

The following technical document on how to create a Golden Image, Is there a bqStudio version?

Hi, Shirish

Thank you for your answer.

From 1 and 2, there was no Chemistry ID similar to BQ STUDIO.

Is my perception below correct?
Acquire log data according to "Simple Guide to Chemical ID Selection Tool (GPC)" and create the following two files.
・ Config.txt
・ Roomtemp_rel_dis_rel.csv

Should I send the above two files to you?

I think that the log is acquired using the log function of bqStudio, but is it okay to create log data separately using a data logger or charge / discharge tester?

Do you agree with the recognition that I will get the data according to the "Simple Guide to CEDV Data Collection for Gauging Parameter Calculator (GPC)"?

Hello Koki,

Details for collecting log files are here https://www.ti.com/tool/GPCCHEM

You will need to zip up the 2 files and then upload it on this page. You will get the report via email.

You can post the report on e2e is there is no good match.

Make sure to use bare cells(no protector) for generating the log

Hi, Shirish

Thank you for your answer.

What does "bare cells" mean?
I'm wondering if it's okay to create separate log data using a data logger

Thanks,

Hi, Shirish

Thank you for your answer.

We have completed the Chemistry ID acquisition. Next, we are creating a Golden Image,and I have a question about Ra Table.

Is it possible to create an Ra Table at different temperatures? The temperature change assumes several patterns from low temperature to high temperature.

There is no mention of temperature in the materials provided by TI. I would like to know if it is possible to perform the Learning Cycle multiple times at different temperatures.

Thanks,

Koki

Hi, Shirish

The method you have guided us (For very low temperature operations, typically below 5C) is when I need to operate at low temperatures, right? I am wondering if I can make a Ra Table by measuring several patterns from low temperature to high temperature.

Thanks,

Koki
