Abstract
A method for determining the temperature change of a feeder cable of a charging device in that, in a first task, the electromagnetic input pulse is coupled into the feeder cable, the electromagnetic input pulse being able to be reflected in the feeder cable and the reflected portion returning to the charging device as reflected electromagnetic output pulse; in a second task, the pulse shape of the reflected electromagnetic output pulse is determined; in a third task, the pulse shape of the reflected electromagnetic output pulse is compared to a reference pulse shape of the reflected reference pulse; in a fourth task, the temperature change is determined by comparing the two pulse shapes.
