Device for charging internal combustion engine of vehicle, has turbine arranged in exhaust gas stream of engine arranged and driven by exhaust gas stream, where turbine indirectly drives generator independent of electromotor

摘要

The device (1) has a compressor (4) for compressing air supplied to an internal combustion engine (2). An electromotor (5) drives the compressor. A turbine (11) is arranged in an exhaust gas stream of the combustion engine and driven by the exhaust gas stream. The turbine indirectly drives a generator (10) that is formed independent of the electromotor. A gear box is arranged between the turbine and the generator and/or between the compressor and the electromotor, where the turbine and/or the compressor are formed in multiple stages.
