Abstract

The electric heating system, in particular for a hybrid vehicle or electric vehicle, is provided with a heating module (10). The heating module (10) is provided with an electrically insulating, heat conducting ceramic substrate (14) which has a heating zone (16) and a control zone (18) which are spaced apart from one another. The heating module (10) comprises an electrical resistance heating element (22) which is arranged on the ceramic substrate (14), in the heating zone (16) thereof, and which is embodied as a resistance heating conductor (24) which is mounted on the ceramic substrate (14). Further, the heating module (10) comprises a transistor (26) for controlling the current through the resistance heating conductor (24), wherein the transistor (26) and other optionally present electrical components (28) and conductor tracks (30) are arranged in the control zone (18) on the ceramic substrate (14). The heating module (10) is provided with a first cooling element (42) which is thermally coupled to the heating zone (16) of the ceramic substrate (14).
