Hi all,

We don't have EV2400 or EV2300.

We designed a board that is identical to Tida-00982.

We use a 2 cells battery (7.4 V) with a capacity of 3000 mAh.

How can we set the data flash memory.

Is there any ".gg.csv" file for Tida-00982 that we can use ?

Thank you.

No, we don't have stock gg.csv files for the gauge. However you can change design capacity and qmax to 3000 for 2 cells and set DA Config: CC0, CC1 to 01 and then run a learning cycle per https://training.ti.com/bq40z50-setup-and-going-production after finding out chemistry data using GPCCEDV for bq4050 or GPCCHEM for bq40z50.

Thank you Batt for your reply.

I generated "GPCPackaged.zip" with bqstudio and upload it to GPCCEDV. But the reply is "MiscInfo.txt" file containing the following message "ProcessType=CEDV".

The ProcessType was equal to 1. "ProcessType=1".

I un-zipped "GPCPackaged.zip" and changed this ligne in "config.txt" from "ProcessType=1" to "ProcessType=CEDV" and re-zipped "GPCPackaged.zip".

I then upload the new "GPCPackaged.zip" to GPCCEDV. But at this time, there is no reply from gpc_do_not_reply@ti.com.

What can be the problem ?

The tool is up, we just checked. I have informed the server personnel to restart the tool. Please check again.

Hi,

Please upload your log here so that we can check it. It looks like it might be a problem with your log as the tool is up.

Thank you Batt for your help,

The 6 log files are the following:

log_files.zip

And the configuration is:

Number of series cells: 2

Cell termination voltage in mV: 3000

SOC % where FCC learned: 7

Top SOC % interval to fit: 9

Bottom SOC % interval to fit: 3

Chemistry type: LiCoO2

Please read the GPCCEDV document. Your logs need to be at a 1s interval with a small rest period before and after the dsg. None of the files in the zip attached meet the requirement.

Thank you Batt for your reply;

But in the example of the GPCCEDV document, the log example doesn't have a 1s interval:

Hi,

Please open bqstudio, click on menu Window, Preferences, Registers and change logging interval from 4000 to 1000 in the scan/log interval (milliseconds) text box and click OK. Now, when you start logging some lines may be logged at a >1s interval but it's OK so long as it comes from bqstudio.

Because of the holidays, TI E2E™ design support forum responses will be delayed from Dec. 25 through Jan. 2. Thank you for your patience.
