BQ79758-Q1: Unbalanced cell balancing configuration

Satoshi
Guru 19645 points
Part Number: BQ79758-Q1

Tool/software:

One customer is trying to control 14-cell x2 batteries using a combination of BQ75758-Q1 and a 12-cell preview product, connecting 12-cell with the preview product and 14-cell +2-cell with BQ75758-Q1.

In this case, could this affect synchronization or cell balancing accuracy?

Best regards,

Satoshi

    Any update on this?

    There are updates and corrections, which are listed below.

    - I confirmed again and found that 14-cell x2-module was incorrect.

      The correct is 28-cell x1-module.

    - By the way, 12-cell preview is TI's product.

    Best regards,
