The invention relates to a method of estimating the temperature at the core of a module (10) of a traction battery of an electric or hybrid vehicle in which is packaged a plurality of electric charge accumulating elemnts (11), characterized in that the temperature (y) is measured at the level of an exterior wall (13) of the battery module (10) and in that an estimation of the temperature is calculated. Formula (I) at the core of the battery module (10) on the basis of the measurement of the temperature (y).
