IMPROVED CHARACTERIZATION OF AN ELECTROCHEMICAL DEVICE IN OPERATION FOR A FUTURE FUNCTIONING PROGNOSIS OF THE DEVICE

A characterization of an electrochemical device in operation for a future functioning prognosis of the device with, in particular: a storage in memory, for a given device type, of a plurality of variation models over time of at least one functioning parameter of the device, according to respective operation points of the device, and the implementation of a processor accessing this memory and comprising at least one connection to the device to: obtain an item of information relating to a current operation point of the device, recover in the memory, at least one variation model corresponding to the current operation point of the device, receive from the device, at least one measurement of a current value of the functioning parameter, compare said measurement to the variation model recovered from the memory, to temporarily locate the functioning of the device, and, from there, estimate a functioning prognosis of the device.
