BQ34Z100: Gauging Parameter Calculator (GPC) Tool sysrate calculation failure

THis is the error I get.. 

Warning: Automatic firmware properties detection failed. Rb_select defaults to 2. Please make sure that chem ID loaded in the GG file is the same as ID specified in the config.txt
Warning: Automatic firmware properties detection failed. basescale defaults to 1. Please make sure that chem ID loaded in the GG file is the same as ID specified in the config.txt

In the meantime I have repeated this process with another different zip entry that had worked in the past and I get the same results:

Let me take a look at your files first. Also, I will submit your files by myself and see what might be wrong.

IT would be greatly appreciated! We are in production but updating our battery chemistry profiles.

We cannot  proceed until this is resolved.

If you need additional data let me know.

Hello Yevgen,

I have updated the gg.csv file and device to the recommended Chemistry 0808 (see attached)

Now I am getting different errors.

You need to perform actual programming of chem ID 808 using bqstudio, so that Ra values will become default.

Your Ra values are:

Ra Tables Ra0 Table Ra Flag ff55
Ra Tables Ra0 Table Ra 0 16
Ra Tables Ra0 Table Ra 1 13
Ra Tables Ra0 Table Ra 2 12
Ra Tables Ra0 Table Ra 3 11
Ra Tables Ra0 Table Ra 4 11
Ra Tables Ra0 Table Ra 5 11
Ra Tables Ra0 Table Ra 6 12
Ra Tables Ra0 Table Ra 7 13
Ra Tables Ra0 Table Ra 8 14
Ra Tables Ra0 Table Ra 9 15
Ra Tables Ra0 Table Ra 10 15
Ra Tables Ra0 Table Ra 11 17
Ra Tables Ra0 Table Ra 12 20
Ra Tables Ra0 Table Ra 13 23
Ra Tables Ra0 Table Ra 14 22

The actual default value for 808 are:

Cell3 R_a flag = FF55
Cell3 R_a 0 = 94
Cell3 R_a 1 = 77
Cell3 R_a 2 = 70
Cell3 R_a 3 = 63
Cell3 R_a 4 = 64
Cell3 R_a 5 = 64
Cell3 R_a 6 = 70
Cell3 R_a 7 = 77
Cell3 R_a 8 = 84
Cell3 R_a 9 = 89
Cell3 R_a 10 = 91
Cell3 R_a 11 = 103
Cell3 R_a 12 = 120
Cell3 R_a 13 = 137
Cell3 R_a 14 = 131

You values can be either equal to default, or equal to  default / 4, depending on the firmware.

However, they are neither of these tho cases, which indicates that chemistry was not programmed prior to exporting the GG file.

I just checked again.

I selected the 0808 chemistry from the chemistry tab as shown below and successfully updated my device pressing "Update Chemistry from Database". 

Then I view the Ra tables by going to the data memory tab and clicking on Read All. My tables are updated to be as before.. not what you are suggesting:

Ra Tables Ra0 Table Ra Flag ff55
Ra Tables Ra0 Table Ra 0 16
Ra Tables Ra0 Table Ra 1 13
Ra Tables Ra0 Table Ra 2 12
Ra Tables Ra0 Table Ra 3 11
Ra Tables Ra0 Table Ra 4 11
Ra Tables Ra0 Table Ra 5 11
Ra Tables Ra0 Table Ra 6 12
Ra Tables Ra0 Table Ra 7 13
Ra Tables Ra0 Table Ra 8 14
Ra Tables Ra0 Table Ra 9 15
Ra Tables Ra0 Table Ra 10 15
Ra Tables Ra0 Table Ra 11 17
Ra Tables Ra0 Table Ra 12 20
Ra Tables Ra0 Table Ra 13 23
Ra Tables Ra0 Table Ra 14 22

We  programmed ChemID 0808 to bq34z100 v0.16 and got the following values,

which coincide with defaults.

This is with the bqStudio 1.3.97 and Chemistry version 759

What version are you using for both bq34z100 and bqstudio?
What chemistry updater version do you have?

Still failing.. but for other reasons:

Here is the report

0 0
Warning: DODdifference before and after discharge less than 70% Qmax accuracy reduced: -13.8374126502211
Warning: Voltage under load 2144 mV is higher than OCV 2140mV. Please check correctness of your chem ID. 0

HEre is the data

sysrate_rel_dis_rel (CHM8 AGM 01-18-2020).zip

These error reports indicate the ways in which you data is not matching the requirement by the tool that is described in documentation:

>Warning: DODdifference before and after discharge less than 70% Qmax accuracy reduced: -13.8374126502211

This means that you have 13% of SOC difference between start and end point, whereas at lest 70% is required. You have to charge

battery to full and discharge to empty to get >70% SOC difference.

>Voltage under load 2144 mV is higher than OCV 2140mV. Please check correctness of your chem ID. 0

This indicates that chemical ID might be incorrectly chosen because OCV of this chemical ID is actually lower then you discharge voltage.

You might need to rerun chemical ID selection to verify that ID you are using is correct. 

Sometimes this issue can happen due to overcharge - if you charge the cell higher then specified voltage and taper current, you can have voltage under

load higher then OCV.

Yevgen,

Thank you for the detailed response!

Your information helps me a lot.

I will recheck our profile setup and then re-run the charge and discharge with corrected information.

Let me leave this thread open for a few days and I'll get back to you with confirmation of success.

This may not be related but I cannot get a valid response back from the GPC TOOL:

Attached is my submittal zip file and subsequent report.

Can you please let me know what I am doing wrong?
