Hybrid & Alternative fuels
Further tightening of CO2 and emission limits has triggered new powertrain concepts for the future. Electrification is an especially promising solution and is already today used in several platforms. By electrifying the powertrain of a vehicle, the internal combustion engine is either supported (hybrid concept) or fully replaced (BEV – battery electric vehicle) by an electric drivetrain. This electric drivetrain is powered in the best case by a highly efficient Lithium-Ion battery.
The Hybrid concept combines the established internal combustion engine with an additional electric drivetrain. The vehicle can then be operated in such a way as to reduce significantly fuel consumption and emissions. In general, there are two possibilities to combine both drivetrains: “Serial Hybrid” or “Parallel Hybrid”. In the serial hybrid concept, the combustion engine is only used to generate electric power for the electric drivetrain, with no mechanical link between the combustion engine and the wheels. Examples of this layout include the Opel Ampera, the BMW i3 with Range-Extender and the Volvo 7900 bus series. In the parallel hybrid concept, both the internal combustion engine and the electric motor are connected to the wheels. This opens a range of possibilities for optimizing operation of both engines.
Figures on the right depict the possible location of the electric motor within the complete drivetrain.
Depending on the mechanical location of the electric engine, different levels of assistance are possible. While a P0-configuration, normally operated at 48V, enables additional functions such as regenerative braking, torque smoothing and power assist of the ICE, the P1 – P4 configuration is operated at much higher voltages (> 60V) and provides a pure electric driving experience.
