CHARACTERIZATION OF AN AGING ELECTROCHEMICAL BATTERY CELL

摘要

Method for characterizing an electrochemical battery cell comprising a step of obtaining (21) a first set of information comprising voltage measurements at the terminals of the cell, said measurements being associated with current intensity values circulating, a generation step (22) with a predetermined model of a second set of information comprising voltage values expected at the terminals of the cell in the event of circulation of intensity currents taken from among said intensity values, a step of evaluating (23) a difference between the first set of information and the second set of information, and depending on the position of said difference relative to a predetermined threshold, a step of modifying (29) said model predetermined or keeping said model unchanged.
