BQ34Z100: GPC Tool Rejecting CSV file

Hello Adrian,

Can you attach the zip file that was uploaded?

3404.roomtemp_rel_dis_rel.zip

Hi Shiresh.  Thanks for your reply.  Zip file attached.

Hi Shiresh.  My original file had the CR/LFs but I took them out because the tool said it wasn't in the correct format.  Unfortunately, I deleted that file.   This really is way harder than it needs to be.

Hi Shiresh.  I managed to recreate the original zip file and got the above error again.  Zip file attached.

1.5Cell.zip

The column numbers must start with 0 instead of 1 (adjust all by 1 )

Thanks Shiresh, that worked, but the output is no good again.  Please see report attached - can you give me any guidance why this isn't working?  I followed the instructions exactly.

Hello Adrian,

The data values are the cause of the error. There are also some empty values that could cause issues.

Make sure that you used bare cells(no protector) to collect the data

Thanks Shirish.  Is there anyone in the UK that can help with this as I am very quickly running out of time?

Hello Adrian,

The GPCCHEM tool is automated. You will need to collect data again.

The data is wrong. Voltage is dropping when current is 0.

Graph of data, see the portion after discharge

Thanks Shirish.  I am using the BQ34Z100 as a system side device.  The current through the load is measured by the BQ34Z100, but the current drawn by the BQ34Z100 and associated PIC micro is not.  If I let the voltage drop below 2.5V, then the battery doesn't power the BQ34Z100 for the  5 hours required to record the relaxation period.  Should I power the BQ34Z100 and PIC from an independent supply?

Hello Adrian,

The bq34z100 can be used on system side but with limitations. It can only gauge the same battery.

For GPCCHEM logs, you cannot have any other circuitry connected. Just the gauge to measure and log. And yes, you can power the gauge with an external source. The PIC/system side circuitry must be removed or it can be part of the load if it draws a constant current. Make sure to discharge at the correct rate.

Thanks Shirish.  I am now trying a ChemID cycle using the evaluation board with an independent supply for the BQ34Z100.  I'll let you know hoe it goes :)
