1. Apparatus for evaluating a dynamic parameter of an element embedded in a system of interconnected electrochemical cells or batteries, said element bounded by first and second electrical contact points, comprising:

  • dynamic parameter measuring circuitry simultaneously coupled to said first and second contact points and rendering a first dynamic parameter measurement, simultaneously coupled to said second contact point and to a third electrical contact point displaced on a conducting path from said second contact point and rendering a second dynamic parameter measurement, and simultaneously coupled to said third contact point and to said first contact point and rendering a third dynamic parameter measurement, and;

    computation circuitry adapted to compute said dynamic parameter of said element from said first, second, and third dynamic parameter measurements.
