Power-split Hybrid
A power-split hybrid uses a planetary gear to combine engine and motor power.
What is Power-split Hybrid?
It acts like a continuously variable transmission. It can drive electric only at low speed. It is used in many full hybrids. Two electric motor-generators and the engine are connected through the planetary gear, and the system controls their speeds to keep the engine efficient. It is often described as an electronic CVT. The design is mechanically simple, with no clutch or conventional gearbox, and is known for good durability.
How it works
The planetary gear splits engine power.
