PROCEDE DE DETERMINATION D'UN ETAT DE SANTE D'UN DISPOSITIF ELECTROCHIMIQUE. |
摘要 |
The invention relates to a method for determining a state of health of an electrochemical device in particular having improved reliability. Said method in particular consists of: applying (10) to said electrochemical device an input signal comprising electrical excitations of different categories, and measuring an output signal (20) including the response signals to each electrical excitation; estimating (41) at least one first parameter from an electrical excitation belonging to a first category and the corresponding response signal; estimating (43) said at least one physicochemical parameter representative of the physicochemical behavior of the device from an electrical excitation of a different category, of the corresponding response signal and said first estimated parameter; estimating (50) said state of health of the electrochemical device as deviation between the previously estimated value of the physicochemical parameter and a reference value. |
