BQ35100: chemID

Diane McLaughlin
Prodigy 240 points
Part Number: BQ35100
Other Parts Discussed in Thread: BQSTUDIO, EV2400,

 Chem ID: Is it true that Chem ID can only be set by bqStudio? The documentation on this procedure seems very sparse. If the Chem ID cannot be programmed via the host processor, is the default Chem ID set up for monitoring a single 19Ah Li-SOCl2 battery?

 

What would be the simplest way to get something running on a PC? It seems like we would need the setup below: 

    • EV2400 or EV2300 (any benefit to one vs the other?)
    • BQ35100EVM-795

Thanks - Diane

    Hi Diane,

    bqStudio is the preferred method for setting ChemIDs and creating your gauging files.

    For a set up, you're spot on.

    1 PC, 1 EV2300/EV2400, and 1 EVM.

    The EV2300 includes pull up resistors, whereas the EV2400 does not. The EV2400 is the latest and greatest.

    Sincerely,
    Bryan Kahler

    hi Diane
    Yes bqstudio is the only way to program the chem id.
    -ev2400 is better. The drivers are automatically installed.
    - Yes, that is the set up. pls see the EVM user guide for further setup instructions.

    the default chem id will work for the battery.
    thanks
