Hybrid Electric System: Overview: Notes

The hybrid electric system consists of four key components: the internal combustion engine, the TCM, the transmission, and the high voltage traction battery. For a detailed description of each component, refer to HYBRID ELECTRIC CONTROL HARDWARE . In this powertrain configuration, there are two power sources that are connected to the driveline, a combination of the engine and the generator which uses a planetary gear set to connect to each other, and the traction motor which is connected to the drive wheels.

The high voltage traction battery is an electric energy storage device. The electric energy is used by the generator motor and the traction motor.
