Device and method for producing electrical energy from exhaust gas and motor vehicle

摘要

A device and a method for producing electrical energy from an exhaust gas of an internal combustion engine include a generator with an exhaust gas inlet, an exhaust gas outlet and a heat exchange portion therebetween. The heat exchange portion includes a plurality of flow paths for the exhaust gas. The flow paths are at least partially surrounded by thermoelectric elements which are in thermally conductive communication with a cooling device on a side facing away from the flow path. A motor vehicle having the device or carrying out the method, is also provided.
