Hello,

our customer is asking what is the differences between Dynamic Voltage Correlation (DVC) and Impedance Tracking (IT).

could you let us know the pros and cons for those ?

best regards,

    DVC is a voltage based algorithm. There is no current measurement. less accurate that IT. less expensive. use for applicattion where high SoC accuracy isn' creatical and where the customer is cost sensitive
    IT is more robust and accurate hence more expensive.
    thanks
