BQ34Z100-G1: Process of Learning Cycles with Bq34z100-G1

Hi

What is meant for Error code 1470, Chemical ID updation failed ??

Thanks in advance, looking forward to hear from you

Hi Batt,

Thanks for the kind reply,
I already have one "GPC_Report.txt" file generated with the same battery with the same procedure.

but selecting this file giving me Error code. 1713.

Hi Batt,

Thanks for the chem Id database, the database is up to date now, 
but issues of updating chem id remains same,

On updating from the GPCRB file, error code is 1713 "Chemistry Programming failed"
On updating from the available list of chemistry, Error code is 1470  "Chemistry Programming failed"

even I have tried reinstalling the BQstudio, updating chem database again but the same problem persists.

Regards

Hi Batt,

Hope you doing well,

I would like to know a few things here,

1) Every time I open the BqStudio, I receive a warning popup window, screenshot attached "WarningPopup"

2) Where to check the voltage reading and df  "your voltage is higher than flash update voltage in df" wheres this df? screenshot of the main dashboard is attached.
the voltage divider is on 32V as my battery is 28.8V, 20Ah battery

3) I have tried updating chemistry with a new EVM board, it's done without any error, "Chemistry updated successfully"
so I would like to know what that error meant for Error No. 1470 and 1713, how could I repair the board if any h/w fault is there?

and as I have lost one EVM board, I would like to know step by step procedure with proper precautions for generating the golden image.
like Chemistry is updated successfully next is to fill a few data like taper current, capacity, energy, etc I have to fill manually or it may get updated with chemistry id updation... what should I have to do now..??
with proper sequence.


Thanks in advance

Sonu,

Please allow me until Tuesday next week to get back to you. I will most probably reply earlier.

Hi Batt,

No issue at all,
I'm thankful for your concern

Hi Batt,

Thanks alot for the kind assistance,

I have changed the voltage dividers on <=5, and the ChemID is updated successfully.

Now as on the second step I have to edit a few parameters of Data Memory
I have found few parameters under configurations and Gas gauge tab of DataMemory(Design Capacity, taper Current, Dsg Current threshold, Chg current threshold, quit current threshold).
but a few are creating confusion, like where to fill

Design Voltage, Term voltage? is Cell termination voltage is the synonym of Term Voltage?
and what should be the value of design Energy?

secondly, I have to left other parameters unedited like
Cell Charge voltage T1-T2 4200(default value)
Cell Charge voltage T2-T3 4200(default value)
Cell Charge voltage T3-T4 4100(default value)
same Charge Current btw T1-T2, T2-T3, T3-T4?

but these parameters seem to be set for 5v battery,

So I'm attaching screenshots of data memory.
Please have a look on Screensot shared,

Thanks in advance

Hi Batt,

I have gone through the documents, and started the learning cycle,
first discharging cycle was accomplished with C/10 load, then after 5-6 hours of rest period after completion all registers are updated as mentioned in the doc,
so started charging as the second step, 

during charging cycle for a moment Bqstudio displayed USB not connected, so I tried to refresh the dashboard but nothing happens so I plug out and plug in the USB. connection established but few registers shown as RSVD, ScreenShot attached. 
After charging cycle and 2-3 hours of rest, update status should be 05 but it's still 04, RUP_DIS is clear but VOK is still high whereas VOK should go low.

So I would like to know should I proceed with the next step of "discharging the battery" with default values or manually change update status to 05 and proceed or REstart from the beginning.

or restart the process as something gone wrong.

moreover, I have one more query regarding the icon of battery in dashboard why it always shows near about 596mV to 610mV, SS attached.
