Abstract: The invention relates to a method for operating an electric charging control device (10) of an electric vehicle (11), whereby, in order to charge at least one battery of the electric vehicle (11), a charging cable (19) with a charging plug (20) is plugged into a charging socket (12) that has a charge port door (13) and that is part of the electric charging control device (10), and at least one charging operation is controlled by means of a charging communication chip (17) of the electric charging control device (10). In order to activate (31) the charging communication chip (17), the at least one detection device (14) detects an open/closed state (15) of the charge port door (13) and emits this state in at least one generated detection signal (16), whereby the charging communication chip (17) is activated from a deactivated state (30) when the charge port door (13) is opened.

Abstract: The invention is directed to a method of determining gas concentrations in a gas mixture comprising more than one component, in which thermal conductivities of the gas mixture are determined at different temperatures, deriving therefrom the individual gas concentrations. The invention aims to improve upon this method by enabling the accuracy of measurement to be enhanced, the sensitivity to external influences to be diminished, and the constructional expenditure of a measuring apparatus to be reduced.
