Abstract
The present invention relates to a method for determining the lifetime of an electrochemical element of a battery in real time as a function of a determined application, applicable in the field of primary type batteries. The method comprises: —a step () of measuring at least one intensity value (I) of the current provided by the electrochemical element and of measuring at least one temperature value (T) of the electrochemical element in the determined application; —a step () of computing total lifetime allowing the availability time of the electrochemical element to be computed on the basis of a determined initial time, as a function of the one or more current intensity value(s) (I) and of the one or more temperature values (T) measured during the measuring step (), as a function of a determined value of the capacity of the electrochemical element, of the cut-off voltage of the determined application, and of the background current of the determined application.
