Part Number: BQ40Z60EVM-578
Other Parts Discussed in Thread: BQSTUDIO

Hi, 

Is there a doc outlining the setup for a 2S6P in the bqStudio using a bq40z60EVM-561:

2S6P

2 x 20400mAh

using Panasonic NCR18650B (?2012? four choices).

need something for the bq40z60EVM-561 GUI similar to the attached showing the bq20zxx EVM DataFlashSettings...slva208b

bq40zxx_EVM_DataFlashSettings_slva208b.pdf

it gets a little confusing in the bqStudio when to enter 1S voltage values (default) or 2S voltage values...(??) for:

Data Memory:

- Advanced Charge Algorithm

- Gas Gauging

- Gas Gauging/State (Qmax Cell1, Cell2, CellPack)

- Protections

please help....

thanks,
Tom

    instead of the above posted

    Hi Tom,

    Unfortunately, such a document does not exist. The bq20zxx is most applicable task based app note, but must be read with the TRM as as supplement.

    Fortunately, you're on the correct path. You have found the proper documentation for the device, unfortunately, there are no shortcuts through this device. In addition to the documentation you have linked, the best guide to configuring this device is the TRM found here: www.ti.com/.../sluua04d.pdf

    The default values indicate whether or not the parameter refers to a single cell or the stack.

    Some general tips:
    Set number of series cells in DA Config
    Charging voltage values are based on a single cell
    Charging currents are based on the total mAh capacity of the pack
    - Generally units of mA or mAh will be based on the total capacity of the pack
    Some protections can be set at the cell level while other protections can be set at the pack level
    - The most commonly used protection features are enabled by default
    - There are a lot of protection features and they need to explored individually.

    If you have any specific questions about a feature, please let me know!

    Sincerely,
    Bryan Kahler
