Zusammenfassung:A method for determining the impedance of an energy storage element of an electric battery comprises the steps of: applying a predetermined sequence of current variations to the element; measuring the voltage variations at the terminal of the element in response to the application of said sequence; and determining the impedance of the element from the measured voltage variations, wherein said is a non-binary sequence produced by the convolution of a pseudo-random binary sequence with finite impulse response filter coefficients.
