A hybrid vehicle is a vehicle that uses two or more distinct power sources to move the vehicle.[1] The term most commonly refers to hybrid electric vehicles (HEVs), which combine an internal combustion engine and one or more electric motors. However other mechanisms to capture and utilize energy are included. Power Power sources for hybrid vehicles include: * On-board or out-board rechargeable energy storage system (RESS) * Coal, wood or other solid combustibles * Electricity * Electromagnetic fields, Radio waves * Compressed or liquefied natural gas * Human powered e.g. pedaling or rowing * Hydrogen * Petrol or Diesel fuel * Solar * Wind Vehicle type A biodiesel hybrid bus in Montreal …show more content…
Rail transport Main article: Hybrid train East Japan Railway Company HB-E300 series Europe The new Autorail à grande capacité (AGC or high-capacity railcar) built by the Canadian company Bombardier for service in France. This has dual mode (diesel and electric motors) and dual voltage capabilities (1500 and 25000 V) allowing it to be used on many different rail systems.[7] The locomotive has been on trials in Rotterdam, the Netherlands with Railfeeding, a Genesse and Wyoming company. China The First Hybrid Evaluating prototype locomotive was designed and contracted by rail research center MATRAI in 1999 and the sample was ready in 2000. It was a G12 locomotive that was converted to hybrid by using a 200KW diesel generator and batteries and also was equipped with 4 AC traction motors (out of 4) retrofited in the cover of the DC traction motors. Japan The first operational prototype of a hybrid train engine with significant energy storage and energy regeneration capability was introduced in Japan as the KiHa E200. It utilizes battery packs of lithium ion batteries mounted on the roof to store recovered energy.[8] North America In the U.S., General Electric introduced a prototype railroad engine with their "Ecomagination" technology in 2007. They store energy in a large set of sodium nickel chloride (Na-NiCl2) batteries to capture and store energy normally dissipated during dynamic braking or coasting downhill. They expect at least a 10% reduction in fuel use
The author first explains what a hybrid is, stating “A hybrid is a cross between two established varieties of plant, animal… or technology.” She introduces the hybrid vehicle, a new form of technology that stands as a possible answer for a vehicle that is both energy preserving and safer for the environment. Before she dives into details of how the vehicle works, she enlightens the reader on what the article is about and the objective of the hybrid vehicle. Students enrolling in an engineering course in a post-secondary institution will be more
Around 1900, a fleet of electric taxi cabs took to the streets in London, but the first gasoline/electric hybrid was built near Chicago. That vehicle, however, was not a commercial success because it was too expensive, it was too slow, and it was a challenge to maintain.
Electric and pedal power hybrid bicycles make a lot of sense to commuters. With a small amount of battery power to augment your pedalling efforts, you can achieve extra speed and distance while leaving a minimal environmental footprint and paying next to nothing per kilometre. One can ride a bicycle almost anywhere, at any time of the year, and at lowest cost!
A hybrid electric vehicle (HEV) is a type of hybrid vehicle and electric vehicle which combines a conventional internal combustion engine(ICE) propulsion system with an electric propulsion system (hybrid vehicle drivetrain). The presence
Hybrid cars are built on the advantages of both combustion engine cars and battery-powered electric motor cars, and the hybrid cars will be an alternative to combustion engine cars until next step technologies such as fully electric vehicles or fuel-cell powered vehicles will take over. This article supports the ideas shown in the main source through hybrid vehicle technology.
I. A hybrid car is a vehicle with more than one power source such as a small internal combustion engine and an electric motor.
The article “The Gas-Electric Hybrid Demystified” by Sara R. Howerth, gives the reader some insight on the new developed technology of hybrid cars. The author uses the difference between four engine models; Gas-Engine, Battery Powered Electric, Hybrid model #1 and Hybrid model #2 – to show just how far technology has come and to say that this is only just the beginning. The engine will keep evolving as long as our natural resources continue to diminish and our need for them increases.
Now they face a big decision, they have a big success with EVO engine, and a big project that is just starting to make regional the production and commercialization of the Transportation department by the design of the Global Modular Locomotive or GML that requires a
One new technology that has affected people’s lives is the electric train .Electric trains have help us to get to our destination faster and more efficiently than any normal wasteful train.
High-speed electric trains today are extremely fast, but they are mostly used in Europe and other places, like Japan. Future trains in America, and around the world, could have a more futuristic look to them. A man named Elon Musk proposed the idea of a “vac-train” after he “revived an
Scientists and engineers are eagerly trying to come up with some sort of alternative or proposed solutions to the waste the automobile creates. One proposed solution is the electric car. Electric cars were once thought to be
The main component of a car would be the power that actually puts the car in motion. To be solely dependent on one power source is not a very good idea as it is not eco-friendly and at the same time not suitable. By 2040, half of all the new cars being sold will be hybrids, according to Exxon Mobile. Hybrid Cars are the cars that uses more than one power sources to run the car. It is usually referred to the Hybrid Electric Vehicles (HEVs) which has both the internal combustion engine and electric motors that generates power. One of the main problem with these hybrid cars is that their batteries are extremely heavy and takes up a large amount of space in the car. The concept of Hybrid cars can be a good thing to the environment, but definitely not for the car manufacturer or the customer. Hybrid cars have a convincing amount of weight due to their batteries, even with the existence of lithium-ion batteries. As a solution, Energy Storing Body Panels are used.
These cars operate from a rechargeable battery and gasoline. The engines are smaller so that they will be able to accommodate the 99% of time when the car is not going uphill or accelerating quickly. The battery is used to give extra acceleration power if needed. When the car is stopped, hybrid gasoline motors can shut off and run off their electric motor and battery. These cars are aerodynamic and the tires are often stiffer and inflated higher to reduce dragging.
Electric motor - 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.
Abstract- This paper deals with the different motors used in the hybrid electric vehicles. The performance like the efficiency of induction motor, internal permanent magnet motor and switched reluctance motor is studied. In recent years permanent motors are often used for driving HEV. This paper compares the characteristics of Permanent Magnet (PM) motor with Switched Reluctance Motor (SRM) and Induction Motor (IM) and gives us prospects for future development of HEV using these motors.
