The internal combustion engine runs and drives the electrical machine as an alternator. The generated three-phase alternating stress is converted by the power electronics control unit (N129/1) into direct voltage (high voltage) and stores it in the high-voltage battery (A100g1).

The power flow takes place from the internal combustion engine to the rear axle. The internal combustion engine also drives the electrical machine as an alternator. The generated three phase alternating stress is converted by the power electronics control unit into direct voltage (high voltage) and stores it in the high-voltage battery.

The power flow only takes from the internal combustion engine and from the electrical machine to the rear axle. The high-voltage battery supplies the electrical machine with electrical energy. To do this the power electronics control unit converts the direct voltage (high voltage) into three phase alternating stress. The electrical machine reacts by generating a torque, which acts on the drive supportively to the torque of the internal combustion engine.

The power flow takes place from rear axle to the electrical machine. The kinetic energy of the vehicle is converted by the electrical machine into electrical energy (three phase AC voltage). This energy is converted by the power electronics control unit into a direct voltage (high voltage) and charges the high-voltage battery with this.

The power flow takes place from the electrical machine onto the drive. The high-voltage battery supplies the electrical machine with electrical energy. To do this the power electronics control unit converts the direct voltage (high voltage) into three phase alternating stress. The electrical machine responds by generating a torque, which acts on the drive.
