Hello All,
I am new to the TI bq series of battery management ICs. I have prior battery management circuit & software design experience.
I have a high-current 12 volt battery pack application in which I would like to use one of the bq series ICs for protection, monitoring and gas-gauging. The pre-selected LI-Ion battery pack uses series and parallel cells.
In reading the various data sheets, app notes, design guides, etc, I find little mention of parallel cell topologies. Is there a specific app note which deals with the application of series-parallel packs to the bq series? What are the tradeoffs involved in using a series-parallel pack vs a series-only pack with the bq series ICs? That is, it seems the bq series is feature-rich with a phenomenal set of measuring, monitoring & safety functions. How is the efficacy and accuracy of these functions affected in a series-parallel topology environment?
Thanks
