Part Number: BQ34110EVM-796
Other Parts Discussed in Thread: BQ34110, BQSTUDIO

Hi,

I am  working with bq34110 for NiMh multi cell battery,  I am using ev2300. I  successful calibrated the voltage current and temperature using bqstudio.

I am trying to create  the log files required. I am trying to  create the log files using the bqstudio.

I clicked into the gpc cycle automated mode

They ask to enter the termination voltage EDVo

Then I can  see six different flow diagrams

for eg

low temperature low rate

start- charge-relax-discharge-end

I have fully charged my battery then

I have connected the battery in bat+ and bat- of my board

connected the load in bat+ and pack-

I am a  bit not sure about the next step...

start_charge ..am I supposed to do this while charging the battery..

or am i supposed to do this with a fully charged battery.

If I can get some guidance with the set up to create log file it will be very helpful.

    Hi Jofonia,
    Pls refer to the user guide for the EVM. www.ti.com/.../sluubi1

    When you start bqstudio, there is a start log button. You need to carry out your discharge using your electronic load and charge using your power supply or a charger.
    thanks

    Hi Onyx,

    I have gone through the TI documents as advised by you.

    I have created the first log files at room temperature, my battery is  NiMH battery with  10 cells total capacity is 14.5 Ah.

    I am attaching the log files to make sure I am in the right direction please correct me if I am wrong.

    Just wanted to confirm the steps after creating the log files, I have gone through the manual just wanted to make sure I have understand it right.

    1. Create 6 log files.

    2. Submit it to the GPC calculator to get the CEDV coeffiecients roomtemp_highrate.log.

    3. The CEDV coefficients are updated in the data memory in the bqstudio.

    4. Then go to the programming screen in the bqstudio and select the bq34119 firmware bundle-002-windows program it followed by executing FW.

    5. I am not quiet sure where the read srec button is after doing Execute FW.

    6.I am not sure about the advanced communication link

    7. I go to the golden image window  and export the firmware as an srec,bq.fs and .df.fs to the output files created  in the bqstudio directory

    Regards,

    Jofina Jijin

    8321.qdscg.zipHi Onyx,

    Thank you for replying.

    I have done a qualifying discharge based on what Bryan advised me.

    I can send you my gg files and log files for qualifying discharge.  Could you please let me know if I  the behaviour in log file for qualifying discharge and gg files correct.

    If yes then am I ready to program the fuel gauge memory.

    Just wanted to check if the steps mentioned in my previous query correct?

    Regards,
