Patent Images
1. A supercharging device for an internal combustion engine with a variable power curve comprising:
- an electric motora compressor that is electrically driven by the electric motor for supercharging the internal combustion engine with air via an air feed passage;
a first power generator driven by the internal combustion engine; and
an electric energy accumulator, which is fed with electric energy via the first power generator,wherein for an energy supply the electric motor is connected to electric energy stored in the electric energy accumulator to drive the compressor independently of a current load or an operating point on the variable power curve of the internal combustion engine at a time.

Abstract
A supercharging device for an internal combustion engine having a compressor that is driven by an electric motor for supercharging the internal combustion engine with air via an air feed passage, and an electric energy accumulator, which is fed with electric energy via a first power generator that is driven by the internal combustion engine. The energy supply the electric motor is connected to electric energy stored in the energy accumulator to drive the compressor independently of a current operating point on a power curve of the internal combustion engine.
