Claim:
1. A method for dynamic characterization of an electrochemical system, said method comprising: (a) selecting an electrochemical system to be characterized at a plurality of times within a selected sampling window, wherein said electrochemical system utilizes electrochemical reactions to provide, use, or store electrical energy, and wherein said electrochemical system is selected from the group consisting of a battery, a fuel cell, a capacitor, an electroplating system, and a galvanic corrosion system; (b) providing a computer in operable communication with said electrochemical system; (c) sensing, in said computer, a plurality of first data inputs each comprising measured current to or from said electrochemical system at said plurality of times; (d) sensing, in said computer, a plurality of second data inputs each comprising measured voltage across said electrochemical system at said plurality of times; (e) receiving, in said computer, a plurality of third data inputs each comprising the time derivative of said measured current at said plurality of times; (f) receiving, in said computer, a plurality of fourth data inputs each comprising the time derivative of said measured voltage at said plurality of times; and (g) calculating an impulse response from said first, second, third, and fourth data inputs using a recursive or matrix-based algorithm, performed in said computer, wherein said impulse response characterizes said electrochemical system within said sampling window.
