BQ34Z100-G1: about GPC tool

Hi all,

I would like to ask you some questions about GPC tool.

Simple Guide to Chemical ID Selection Tool (GPC) (Rev. A)

My customer got a Log of Lead-Acid battery and updated to GPC tool.

However, an error occured.

The following is an errow message.

The following errors were reported by the calculation engine:

Accuracy Error: Deviation is so high that it is most likely due to anomaly in the data. Please check that data files have recomended format, units and test schedule * Warning: Max R deviation ratio can not be checked because discharge hr-rate is above 12. Hr rate = 21.0887965131344 * Warning: Max R deviation ratio can not be checked because discharge hr-rate is above 12. Hr rate = 21.0887965131344 * Warning: Max R deviation ratio can not be checked because discharge hr-rate is above 12. Hr rate = 21.0887965131344 * Warning: All IDs disqualified because of too high resistance deviation. No suitable ID selection available

So I have some questions.

1) Is there any item to specify the material of the battery?

I think there is an error because the battery is recognized as Li-ion and hr-rate is 12.

I think the battery material should be specified as lead acid battery and the Hr rate should be 20.

2)When using 2 batteries for serial connection, is there any problem to set as 2 for 'NumCellSeries' of config.txt?

I think an error occurred because I set 12 here.

Best Regards,

Ryusuke

    Hello Ryusuke,

    Can you share the data submitted and the report you received? I would double check all your units to make sure they are in mV, mA and Deg C. The chem IDs for lead acid appear to be based on single cells, so if you have a 12V lead acid battery the number of series cells should be 6.

    Sincerely,

    Hi Wyatt,

    Thank you for your reply.

    I will attach the report my customer gave me.

    <Test conditon>

    battery: FML12170

    They use 2 batteries for serial connection.

    The total test time is about 35 and half hours.

    CCCV charging

    Charging current setting: 8.5A

    Charging voltage setting: 29.4V

    Charging stop setting: 100mA

    ↓

    Relax for 5 hours

    ↓

    CC Discharge

    Discharge current setting: 850mA

    Discharge stop setting: 21V

    ↓

    Relax for 5 hours

    5700.roomtemp_rel_dis_rel.csv

    3252.config.txt 
    ProcessingType = 2
NumCellSeries = 12
ElapsedTimeColumn=0
VoltageColumn = 1
CurrentColumn = 2
TemperatureColumn = 3

    Best Regards,

    Ryusuke

    Hello Ryusuke,

    I looked at the log shared, the voltage is not following the required units as outlined in the guide, it seems to be 670 near full charge. Based on the configuration submitted the tool thinks that there is 12 cells in series and the voltage is in mV, that means each cell is about 670/12 = 56mV which will lead to no chem ID match.

    Sincerely,
