摘要

In this method of determining, by means of an auxiliary device (24), an overheating of at least one connection terminal (38, 40) of an electrical device (22), or the connection terminals (38, 40), each comprising at least one connection pad arranged to be connected to an electrical conductor (12 ′, 14 ') corresponding. This method comprises for each connection terminal (38, 40) of the steps of measuring a first temperature, at a given instant, to calculate a value of the connection zone, of comparing the value of the connection zone with a threshold temperature, and of the detection of an overheating of the connection terminal (38, 40) when the corresponding value of the heat is greater than the threshold temperature. The method comprises, above the step of comparison, and for each connection terminal (38, 40), a step of calculating the temperature threshold at a given instant, as a function of the threshold value to a previous instant, the value of the temperature threshold is variable between the preceding instant and the given instant.
