Hybrid and electric vehicle system components may include a battery for energy storage, an electric motor for propulsion, a generator, a mechanical transmission and a power control system.
These components are brought together in different ways by different systems. Depending on these factors we can classify the electric car segment into 4 major parts:
Hybrid Electric Vehicle
Plug-in Hybrid Electric Vehicle
Extended-Range Electric Vehicle
Battery Electric Vehicle.
Hybrid Electric Vehicle
The hybrid electric vehicle uses a small electric battery to supplement a standard internal combustion engine and this engine is mainly used to support the gas engine only. It increases the fuel efficiency of the car by 25% at least.
The electric motor aims at minimizing idling and boosting the car’s ability to start and accelerate.
The electric motor accelerates the car to about 40 mph, depending on the vehicle, and then the internal combustion engine takes over.
The battery is recharged by the gasoline engine and regenerative braking. Regenerative braking converts kinetic energy that otherwise would be lost as heat in the brake pads into electricity to charge the battery. The Ford Fusion Hybrid and Toyota Prius are examples of this type …show more content…
So basically this is somewhat like an electric car only with an additional capacity of getting self-recharged. When the driver turns the engine on, power is transferred from the battery pack to electric engine which in turn rotates the wheels. On longer trips (beyond 50 miles or so), the gas engine helps to supply the additional power. Naturally, series hybrids are more expensive than parallel hybrids because they carry larger batteries to provide for the extra power for higher speeds [source: HybridCenter]. The Fisker Karma is an example of a series plug-in hybrid
