Monitoring the change in temperature at the charging cable

The invention relates to a method for determining the change in temperature of a power supply line of a charging device by the electromagnetic input pulse being coupled into the power supply line in a first step, it being possible for the electromagnetic input pulse to be reflected in the power supp...

Beschreibung
Zusammenfassung:	The invention relates to a method for determining the change in temperature of a power supply line of a charging device by the electromagnetic input pulse being coupled into the power supply line in a first step, it being possible for the electromagnetic input pulse to be reflected in the power supply line and the reflected portion being returned to the charging device as a reflected electromagnetic output pulse, the pulse form of the reflected electromagnetic output pulse being ascertained in a second step, the pulse form of the reflected electromagnetic output pulse being compared with a reference pulse form of the reflected reference pulse in a third step, and the change in temperature being ascertained from the comparison of the two pulse forms in a fourth step.
