The Power-Split Hybrid Drive

The Power-split Hybrid Drive







In addition to a combustion engine, the power-split hybrid drive also has a generator and an electric motor. All are located on the front axle. The vehicle is powered by the combustion engine via a planetary transmission or simultaneously via the E-machine on the vehicle transmission. Serial or parallel operating mode can be selected, depending on the whether or not the planetary transmission is activated. In contrast to the parallel hybrid system, the sum of the individual power sources of the two drive types cannot be applied to the wheel. In order for the vehicle to drive, part of the power supplied by the combustion engine is always converted into electrical energy by the generator and released to the wheels via the E-machine. The maximum drive power is the sum of the power from the combustion engine and the battery.
