Hi guys,

just purchased BQ34110 eval board, and have never get such surprising experience :)

after installtion BQ studio and update for 0110_0_02 it finlaly started working and autodetects guage, but still missing chemistry, there is no icon, no help-update-chemistry option,

Do somebody have idea whats wrong? few images continues.

System Win7 64bit

EV2300 Ver 3.1m

Eal board bq34110evm-796

Thanks a lot

Note: I have checked other bq guage and looks at this one chemistry is presented

    Hi Valentin,

    Thank you for the screenshots - they have proved very helpful. Please update bqStudio to the latest version. As of this writing, the latest version of bqStudio is v.1.3.80 and can be downloaded by clicking on the 'bqstudiotest' button on the bqstudio tool page, found here: www.ti.com/.../bqstudio

    There is no chemistry tab for the bq34110 in bqStudio because the bq34110 is a CEDV gauge and does not utilize a ChemID. The chemistry tab is used mostly for IT gauges.

    In general, the flow for using a CEDV gauge like the bq34110 is to:

    1) Calibrate the board
    2) Use the GPCCEDV tool to determine parameters for the battery, found here: http://www.ti.com/tool/gpccedv
    a) This will require taking 6 logs, as described in the gpccedv tool documentation
    b) Logging may be accomplished with bqStudio + EV2400 + EVM or with a tool such as an Arbin or Maccor
    c) Program the returned parameters from the GPCCEDV tool in the gauage
    3) Set parameters in the gauge based on single cell values. These parameters are discussed in detail in the TRM.
    4) Fully charge and discharge the battery
    5) Test for SOC accuracy

    After using the calibration tab to calibrate the board, please click on the 'GPC Cycle' tab. This pane will assist you in running the 6 logs. When the logs have been taken, the 'GPC Packager' tab may be utilized to archive the files into a zip format. The zip file may then be uploaded to the GPCCEDV tool found at: http://www.ti.com/tool/gpccedv

    The results from the GPCCEDV tool will be e-mailed to you, and those values may then be programmed in dataflash for the device.

    Sincerely,
    Bryan Kahler
