Abstract
A turbocharger for an internal combustion engine, in which a mechanical energy flow can be generated for a intake airflow from an exhaust gas flow of the internal combustion engine. The turbocharger includes a mechanical energy converter connected between the exhaust gas flow and the intake airflow, by which converter the mechanical energy flow can be transferred and transmitted. The turbocharger also includes an electrical energy converter associated with the mechanical energy flow for converting electrical energy into mechanical energy, or vice versa, to enable improved intake airflow charging of an internal combustion engine. By means of the electrical energy converter, an electrical energy flow can be selectively branched off to a battery or fed into the mechanical energy flow.
