Beschreibung
Zusammenfassung:	An electrically heatable honeycomb body includes channels and at least one heating disk having at least one first and one second layer stack of electrically conductive material. The first and second layer stacks are interleaved with and electrically insulated from each other. The first layer stack forms a first current path for conducting an electrical current for a first heating circuit and the second layer stack forms a second current path for conducting an electrical current for a second heating circuit. The first heating circuit operates at a power of 300 W to 500 W and the second heating circuit operates at 500 W to 700 W. Exhaust gas of an internal combustion engine can be evenly heated by several independent heating circuits in a common heating disk even with different heating capacities using a simple construction. A method for heating a honeycomb body and a motor vehicle are provided.
