The invention relates to a method for protecting a charging cable (26) for charging a traction battery (3) of an electrically drivable vehicle (5). In this method, a nominal value for the current carrying capacity of the charging cable (26) is determined (50), the current intensity of the current flowing through the charging cable (26) is measured, forming a current value (52), at least one expectation value (55) for the temperature of the charging cable is determined using the nominal value for the current carrying capacity and the current value, and the temperature of the charging cable (26) is measured, forming at least one temperature value (57). The at least one temperature value is compared to the at least one expectation value (47), and if a predetermined difference between the at least one temperature value and the at least one expectation value appears, the presence of a fault (58) is recognised.
