Part Number: BQ79616-Q1
Other Parts Discussed in Thread: BQ79616,

Hi team,

Large energy storage BMS applications without using daisy chain construction for monitoring 16 cells. Could you provide some recommended scheme?

Could you help resolve this case? Thanks.

Best Regards,

Cherry

    Hello Cherry,


    If you only need to monitor 16 cells, then you can use the BQ79616-Q1 without the daisy chain. The BQ79616 has 16 VC/CB channels which can be attached to up to 16 battery cells.

    Hello,

    Thanks for your help.

    And the customer has also noticed the 76952, is this one a good choice? Is there any typical difference between these 2?  Regarding 76952, how about the acquisition cycle?

    Thanks and Best Regards,

    Cherry

    Cherry,

    Yes the BQ75952 is a good product and may be more suited to your customer's application, but it is supported by a different team so I don't know all the details about it. At the high level, it is similar in functionality to the BQ79616, but it is more targeted at industrial applications. The BQ79616-Q1 was developed for automotive applications, though we do have some customer's using for EIS, electric scooter, and other industrial applications as well.
