Abstract

The invention relates to a device (1) and to a method for protecting a charging cable (2) serving to charge electric vehicles. The charging cable comprises at least one phase conductor and a first control line, the voltage level (Us) of which serves as a measure of the current-carrying capacity of the at least one phase conductor, wherein the voltage level (Us) is tapped at an ohmic voltage divider (1). The ohmic voltage divider comprises a first fixed resistor (2) lying outside the charging cable and having a constant resistance value, and comprises a resistance network in the charging cable, wherein the resistance value of said resistance can be changed in dependence on temperature. The level of the charging current can be changed in dependence on the current-carrying capacity measured by voltage tapping.
