Chemistry ID

The Mathcad program did not like the non-zero current data during the rest period. The program predicts ChemID 3180 to be the best match for your cell.

Ok. Thanks for the quick answer.

I need no make more tests with different cells and to calculate the predicted ChemID. After replacing by zero, the non-zero current data in my file, i'm still can't obtain the predicted ChemID for the previous log. I'm using Mathcad 15.0 with the file "chemselect_cont_mcd11_rev37". Can you help me debug the problem?

Please attach the log file and I will try it.

At the time i don't have new files. Help me debug the previous file, in the first post. Can't you send/post the file you used to obtain the previous ChemID, so that i can try it in my Mathcad?

Here is the file that I used.

log_5A.csv

I hadn't understanded that the log should only include the discharging data, that isn't very clear in the chemselect_cont.pdf file.

Another question, in the results table the best ChemID is 319, why did you replied that it was 3180? Did you obtained different results?

	0	1	2
0	2.64575	319	0.358663
1	2.867901	3524	0.550945
2	2.976652	345	0.658106
3	3.027609	3180	0.280826

Thanks for all the help.

I also checked the data with another program and it showed that ChemID 3180 provided the best overall fit to your data.

What another program did you used!?

So basically everytime i need to determinate a ChemID, the best thing is to send/post the log file in the forum? That isn't very good...

Using th Mathcad software i've obtain the chemID of 1298 for a battery. However this chemID isn't listed in the bqstudio software (version 1.3.40) for the BQ78350 BMS.

What should i do regarding the non listed chemID? Can someone please confirm that the chemID 1298 is the best fit for the attached data?
