    Brayts
    Hello, In the past few months i've being working with bq78pl114 for monitoring a li-ion battery pack, but I have some doubts before I end my application, those are: - Can I use a microcontroller like PIC18F2680 to acess the memory of bq78pl114 while is doing polling data? The ideia is replace the...

    ! ! CORRECTION ! ! Statement about impedance learning is updated. If NDI calculations occur, then the impedance values of the cells will be updated. 2) Aux files are dependent on cells and pack construction. Impedance values are not learned over time from some nominal value to whatever your specific...

    Due to mechanical restriction it is not possible to set the current measurement shunt between Ubat- and PACK-, but only between V1 and V2. Seems that then the voltage shift of the current measurement is required. Are there any low power recomendation solutions. Is battery balancing and voltage protection...

    Dear Sercan, one reason could be that one of your cells has no connection to the chip or a very strange voltage. In any case try to relearn / initialize. Make sure that no other device is communicating with the TI chip, this is very critical! Best regards, Dirk
