A method operates a charging connection device for electric vehicles, the charging connection device including a housing inside which at least one temperature sensor constantly senses at least one temperature value. As an essential feature, the maximum permissible charging current is reduced to a specific value greater than zero if a first threshold temperature of a first temperature value is exceeded and the charging process is interrupted if the first threshold temperature has been continuously exceeded by the end of a first interval or when the at least one temperature value exceeds a second threshold temperature of the at least one temperature value. The proposed method of operating a charging connection device for electric vehicles provides for greater availability, better fault tolerance of the charging connection device while ensuring lower production costs.
