In an effort to make energy savings in transportation, technological developments have produced a vehicle called hybrid cars. A hybrid vehicle is a car powered by an engine assisted by an electric motor. In hybrid vehicles, the electric motor helps the engine to help fuel consumption at star up and acceleration.
This means that compared with a conventional car of the same size, hybrids are cheaper to run.

There are three different types of hybrid vehicles today :
1. Pararel Hybrid, where the engine is the main power source to the electric motors provide the necessary assistance.
Engine serve as the main power source. Motor, which provides maximum torque from zero rpm. was called to assist the engine when starting up and during acceleration, when the engine fuel consumption is high. Hybrid is also simple : a parallel hybrid can be made simply by adding an electric motor and batteries an existing vehicle.
The parallel types of hybrid vehicle
2. Combined share the characteristics of series and parallel hybrid design.
The electric motor is only used at low speed, and the engine and electric motor work together at higher speeds.
The electric motor powers the vehicle from a standing start and at low speeds. As speed increases, the engine and electric motor work in combination to efficiently provide the required power.
The system is more complex. showing the power split and generator. This machine is also needed to power the generator.
The Combined Share types of hybrid Vehicle
3. Hybrid running on power from electric motor.
Engine only powers a generator to charge the battery.
The system is the same as powering vehicles with electric vehicle, but also because the vehicle has an engine, it considered a hybrid car.
The Series type of Hybrid vehicle
