bq78PL116EVM, aux file generation
After two days of recording csv data, I got this message from C:\Program Files(x86)\Texas Instruments\bqWizard 3\AuxChemFileUtility.exe
There was a problem found: AuxGen could not calculate all impedance values needed. Please contact TI support for assistance.
What should I do next?
Can you attach the .csv file or send it to me by email? I will review it.
Is your drop box still good? I'll try that first. File is in it now, public folder.
I'm making a new run, is it necessary that the initial discharge be terminated by the safety rules, or can my discharger just shut it off?
I found the file and started working with it. I have not determined what is causing the aux file program to fail yet, but I do have a couple of questions. You used a 3S1P pack for the data collection. You should use your actual pack configuration to create the aux file. I noticed that the first discharge was to a different termination voltage than the second. They should be setup for the same termination voltage. You should use the same charge / discharge thresholds that you plan to use in the production setup. The device should terminate the charge and discharge. The charge and discharge currents can be different from the final setup.
You can then give up with my last cvs file. I'll make a new one with the 7 series cells. Maybe using the details that you provided above, I will get a clean run.
