Energy saving potential of hybrid drive trains. • Various HEV configurations and their operation modes. The Hybrid Electric Vehicle (HEV). What exactly is an. on Hybrid and Electric Vehicle Technologies and Programmes, . term of the Implementing Agreement “Hybrid- and electric vehicles” in

Any vehicle that combines two or more sources of power that can directly or indirectly provide propulsion power is a hybrid. The most commonly used hybrid is gasoline-electric hybrid car which is just a cross between a gasoline-powered car and an electric car.

A 'gasoline-electric hybrid car' or 'hybrid electric vehicle' is a vehicle which relies not only on batteries but also on an internal combustion engine which drives a generator to provide the electricity and may also drive a wheel. In hybrid electric vehicle the engine is the final source of the energy used to power the car. All electric cars use batteries charged by an external source, leading to the problem of range which is being solved in hybrid electric vehicle. One way, known as a parallel hybrid, has a fuel tank, which supplies gasoline to the engine.

But it also has a set of batteries that supplies power to an electric motor. Both the engine and the electric motor can turn the transmission at the same time, and the transmission then turns the wheels.

An electric motor is all about magnets and magnetism: A motor uses magnets to create motion.

We know the fundamental law of all magnets: Opposites attract and likes repel. So if you have two bar magnets with their ends marked "north" and "south," then the north end of one magnet will attract the south end of the other.

On the other hand, the north end of one magnet will repel the north end of the other and similarly, south will repel south. Inside an electric motor, these attracting and repelling forces create rotational motion. DC series motor used in hybrid electric vehicle is a versatile and flexible machine.

It can satisfy the demands of load recurring high starting, accelerating and retarding torques. A DC machine is also easily adaptable for drives with a wide range of speed control and fast reversals. In the diagram shown below we can see two magnets in the motor: The armature or rotor is an electromagnet, while the field magnet is a permanent magnet Using the concept of Hybridization of cars results in better efficiency and also saves a lot of fuel in today's fuel deficit world.

Current State of Military Hybrid Vehicle Development

A hybrid gives a solution to all the problems to some extent. If proper research and development is done in this field, hybrid vehicle promises a practical, efficient, low pollution vehicle for the coming era.

However, the engine on a hybrid will be smaller and lighter, and is more efficient than the engine in a conventional vehicle, because the engine runs at a relatively constant speed, and does not need to provide direct power for acceleration, which is the biggest reason for large engines.

Use advanced technologies to reduce emissions. Gasoline has a much higher energy density than batteries do. For example, it takes about 1, pounds of batteries to store as much energy as 1 gallon 7 pounds of gasoline.

Advanced electronics allow it to act as a motor as well as a generator. For example, when it needs to, it can draw energy from the batteries to accelerate the car.

But acting as a generator, it can slow the car down and return energy to the batteries. Submarines are also hybrid vehicles -- some are nuclear-electric and some are diesel-electric.

Any vehicle that combines two or more sources of power that can directly or indirectly provide propulsion power is a hybrid.

In hybrid electric vehicle the engine is the final source of the energy used to power the car. All electric cars use batteries charged by an external source, leading to the problem of range which is being solved in hybrid electric vehicle. You can combine the two power sources found in a hybrid car in different ways.

One way, known as a parallel hybrid, has a fuel tank, which supplies gasoline to the engine.

A comprehensive review on hybrid electric vehicles: architectures and components

But it also has a set of batteries that supplies power to an electric motor. Both the engine and the electric motor can turn the transmission at the same time, and the transmission then turns the wheels. An electric motor is all about magnets and magnetism: A motor uses magnets to create motion.

A hybrid gives a solution to all the problems to some extent. If proper research and development is done in this field, hybrid vehicle promises a practical, efficient, low pollution vehicle for the coming era. The hybrid car has a gasoline engine much like the one you will find on most cars. However, the engine on a hybrid will be smaller and lighter, and is more efficient than the engine in a conventional vehicle, because the engine runs at a relatively constant speed, and does not need to provide direct power for acceleration, which is the biggest reason for large engines.

Use advanced technologies to reduce emissions. The fuel tank in a hybrid is the energy storage device for the gasoline engine.

Gasoline has a much higher energy density than batteries do. For example, it takes about 1, pounds of batteries to store as much energy as 1 gallon 7 pounds of gasoline. The electric motor on a hybrid car is very sophisticated. Advanced electronics allow it to act as a motor as well as a generator.

For example, when it needs to, it can draw energy from the batteries to accelerate the car. But acting as a generator, it can slow the car down and return energy to the batteries. The generator is similar to an electric motor, but it acts only to produce electrical power. It is used mostly on series hybrids.

The power split device is a clever gearbox that hooks the internal combustion engine and D. The engine starts only after the vehicle attains a certain speed. Once the engine starts it operates on a narrow speed band.

The power split device allows the engine to stay in its most efficient load and speed range most of the time. The batteries in a hybrid car are the energy storage device for the electric motor. Unlike the gasoline in the fuel tank, which can only power the gasoline engine, the electric motor on a hybrid car can put energy into the batteries as well as draw energy from them.

The batteries used in HEV is Ni-Cd cells since its lighter than the lead acid cells and its also mechanically strong and can stand very rough use. The transmission on a hybrid car performs the same basic function as the transmission on a conventional car.

Some hybrids, like the Honda Insight, have conventional transmissions. The armature or rotor is an electromagnet, while the field magnet is a permanent magnet the field magnet could be an electromagnet as well, but in most small motors it isn't in order to save power.In fact, most automobile manufacturers have announced plans to manufacture their own hybrid versions.

In particular the ICE is able to supply the electrical motor or charge the battery thanks to a Fig. How does a hybrid car work?

The numbers of makes and models offered as HEVs are small, and sales are just getting started. Gas motors do better at high speeds and can hybrid by GM - the Mercury Mariner, they admitted they had deliver more power for a given motor weight.
