Abstract
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.

- 16. A method of operating a charging connection device (1) for electric vehicles, the charging connection device (1) comprising at least a first interface (6) for drawing electrical energy from a stationary power supply network, at least a second interface (7, 9) for discharging electrical energy to an electric vehicle in a controlled manner and a housing (2), which housing (2) encloses a plurality of electrical and electronic components (11) and by means of which electrical and electronic components (11) a charging operation of the electric vehicle is controlled and monitored, and at least one temperature value in the interior of the housing (2) is continuously detected by means of at least one temperature sensor (20), and when a first threshold temperature (21) of the at least one temperature value is exceeded, the maximum permissible charging current is re-set from a previously existing initial value to a specific value that is greater than zero but lower than the initial value, wherein the charging operation is interrupted when a fixed first interval (22) during which the first threshold temperature (21) has been continuously exceeded has elapsed, and with every reduction of the maximum permissible charging current the start of a second interval (24) is respectively set and when the second interval (24) has elapsed, it is ascertained whether the first threshold temperature (21) has been exceeded and if it has been exceeded, the maximum permissible charging current is further reduced.
