Abstract
A method of estimating the internal state of a first electrochemical system for power storage is disclosed. The SoC and the electrochemical impedance are determined for different internal states of a second electrochemical system of a same type as the first electrochemical system being studied. An electrochemical impedance model is then defined as a function of the SoC and of parameters. The electrochemical impedance Z of the system studied is determined and its SoC is estimated using the model applied to electrochemical impedance Z.
