Abstract

A supercharging device is disclosed for an internal combustion engine having an exhaust-gas turbocharger and a fresh-air compressor. The supercharging device includes a recuperation charger which has a compressor-turbine with a high-pressure side and a low-pressure side and which has an electromechanical motor-generator coupled to the compressor-turbine. The compressor-turbine is operable at least firstly when the supercharging device is configured in a booster operating mode in a manner driven by the motor-generator as a compressor for increasing the pressure of charge-air mass flow to the intake tract of the engine, and secondly when the supercharging device is configured in a recuperation operating mode in a manner driven by the charge-air mass flow as a turbine for energy recovery by the motor-generator.
