PowerPump - PowerLan

Other Parts Discussed in Thread: BQ78PL116, BQ76PL536

I am evaluating the possibility to use PowerPump technology in our system. At the moment we have 16 60Ah LiFePo4 cells in series. My question are:

 - Max discharge rate is 110A from datasheet, is there any way to extend it to 140-180A

 - Max cell count is 16 cells. Maybe in future we will move to 24 cells. Any plan to increase number of cells?

 

Thanks in advance

    The bq78PL116 will support uto 327AHr Capacities.

    Changing your Sense Resistor Value and making the Appropiate H/W Gain Settings in the bq78PL116 Configuration files will allow you have higher Discharge and Charge Currents.

    Presently, there are no plans for >16s support.

    There are other parts in the TI portfolio that will support higher cell counts and meet your needs. The bq76PL536 is  option.
