BQ34Z100EVM: Configuring the BQ34Z1xxEVM for correct operation with bqStudio

Part Number: BQ34Z100EVM
Other Parts Discussed in Thread: BQSTUDIO, BQ34Z100-G1, BQ34Z100

We still need help getting our bq34z1xxEVM working with the Battery Management Studio and our new Ni-MH battery pack.  Normally, the bqStudio automatically detects the gauges in my EVMs.  -not so with the bq34z1xxEVM.  What version of the Studio should we be using?  Do we have the correct *.bqz file?

What exact *.srec file should we be using and how do we load it into the gauge with the programming screen if the bqStudio doesn’t recognize it?

 

One of my teammates writes:

“When I’m starting the Battery Management Studio and select bq34z100G1 fuel gauge the application warns that the device is not compatible. I have tried both versions available at TI web page (1.3.111.1 and 1.3.101.1) and both say that the device is not compatible. This might be related to the chemistry programming issue.”

-and here’s a screenshot of the error message…

Next, we’re trying to set up to test our new battery pack, consisting of seven Panasonic BK-120AAHU cells in a 7S-1P configuration.  Panasonic shared the following:

Maker

Model

ChemID

Panasonic

BK120AAHU

641

My colleague writes:

“I’m trying to use TI Battery Management Studio to program our battery data. I would like to program battery chemistry id 0641. I have updated chemistry data to version 982 for that purpose. When I try to program the chemistry id, I get the following error message: Chemistry programing failed! Error code = 1721. See attached picture.”

Can you help us get our system running?

Thanks,

  • Hello Carl,

    You should open the gauge manually with the .gg file in BQStudio and then use the SREC file on the product page to program the device. By default the EVMs are shipped with BQ34Z100 firmware, not BQ34Z100-G1 firmware, the BQ34Z100 is not supported in BQStudio until you program the new firmware. That is most likely why you are seeing the error during chemistry ID programming, it maybe memory mapped to the wrong locations, I would not recommend changing or programming anything else until the -G1 SREC is programmed.

    Sincerely,

  • Wyatt, thanks for your reply.  What is the ".gg file" and where do I find it?  How do I "open the gauge manually" with this file?

    Where do I find the "SREC file on the product page?"  I found this link:

    bq34z100-G1 Device Firmware

    ...which allows me to download a file: sluc580.zip, containing an executable: "bq34z100G1FirmwareBundle-0.16-windows-installer.exe"

    What next?

  • Hello Carl,

    Sorry I mistyped, you can manually open the BQZ file (you select right when BQStudio opens and the gauge doesn't auto detect the BQZ) the BQZ files are in the Config folder of the BQStudio download path.

    That's the correct firmware download, when you run the installer it will give you the .srec and .bqz file, program the gauge with the srec file.

    Sincerely,

    Wyatt Keller
