The internal combustion engine comprises an air intake system and an exhaust manifold. The first air charge system comprising a first compressor, a turbine, and a generator/motor module. The first compressor has a first air inlet, a first air outlet, and a first input shaft. The first outlet is connected to the air intake system, the turbine has an exhaust gas inlet, and the exhaust gas inlet is connected to an outlet of the exhaust manifold. The second air charge system includes a second compressor and an electric motor. The second compressor has a second air inlet, a second air outlet, and a second input shaft. The electric motor has an outlet shaft directly coupled for common rotation with the first input shaft of the second compressor.
