BQ40Z50-R2: Chemistry File

Part Number: BQ40Z50-R2
Other Parts Discussed in Thread: BQEVSW, , BQSTUDIO, GPCCHEM

Hello,

I have used the following chemistry file in the past for bq20z95 with bqEVSW;

0401 K2Energy: LFP26650P, K2Energy: LFP18650P (1250mAh)

However, 0401 doesn't appear to be available for use with bq40z50-R2 with bqStudio 1.3.54.1 (26-Jul-2017), even if I update using sluc564fb.zip (10 May 2019).

Is it possible to somehow make this file available?

I suppose I could use;

0442 K2Energy: LFP26650EV (2700mAh), but this is an "Energy", rather than "Power" cell and may not be as suitable.

Thank you,

Jeremy.

    hi Jeremy
    I would recommend you update your bqstudio to the latest which is 1.3.86 and then use the chem updater tool to update the chem id data base.
    Then perform a chem id identification using gpcchem to identify a close match for your cell. This should get you up and running

    thanks

    Hi Onyx,

    I tried this and the chemistry file for K218650P is still not available.

    Furthermore, the 0442 that is available in 1.3.54.1 has also been removed.

    If possible, I'd rather not use a 'close match' in lieu of the actual file, considering the effort TI has put into developing it.

    Is is possible for you supply a chemdat file with the 18650P in it that I could copy into the C:\ti\BatteryManagementStudio\chemistry folder?

    Thank you,

    Jeremy.

    I am not sure what you tried because as you can see below, 401 shows up. You need to chek the include chemistry iDs that do not support turbo mode 2.

    Hi Onyx,

    I'm not sure what happened there - I thought I had tried that check box.

    Perhaps I needed to restart Battery Management Studio after updating the with the zip file.

    In any case, it's up and running now - thank you for your assistance.

    Regards,

    Jeremy.
