Plug-in hybrid Car
A plug-in hybrid electric vehicle operates on a rechargeable battery unit that can be recharged by connecting to an external power source. It shares the attributes of a traditional hybrid electric vehicle, as it is powered by an electric motor supplemented by an internal combustion engine. The most common plug-in hybrid cars are passenger vehicles, although there are utility commercial trucks and buses. Vehicles implementing hybrid drive train technology have been popular among automotive consumers and enthusiasts. The technology has been proven to work, typically saving fuel costs of 25%-40% when contrasted to analogous vehicles with mainstream drive trains (Hummel, 2011). Therefore, to improve fuel economics, car manufacturers are now experimenting with the base hybrid model with the aim of developing a plug-in hybrid car. These cars are built on the traditional hybrid technology with an additional plug-in charging unit.
Plug-in Hybrid Technology
Plug-in hybrid vehicles conserve fuel by integrating a shut-off system that turns off the engine during idling. Modern day hybrid vehicles over short

Prior to depleting its battery charge, the gasoline engine provides the extra power that recharges the battery and powers the vehicle during acceleration. A plug-in hybrid vehicle uses and electric motor as its principal source of power and the gasoline engine as a supplementary (Leitman, 2009). Upon charge depletion, the plug-in hybrid automatically switches to the gasoline engine that helps in recharging the battery. Conventional electric cars can only run for a few miles and take a considerate amount of time to recharge. However, the plug-in hybrid technology yields infinite range and high efficiency, especially for drivers with logical
Electric Cars use the energy stored in a battery (or series of batteries) for vehicle propulsion. Electric motors provide a clean and safe alternative to the internal combustion engine. There are many pros and cons about electric cars. The electric vehicle is known to have faster acceleration. They produce no exhaust.
According to Cars Direct website, hybrid cars can reach 51 MPG wish destroy all gasoline and diesel efficiency expectations. This high efficiency yield to two main reasons: hybrid car tend to be lightweight, and the cooperating between the gasoline engine and the electric motor. ” According to consumer reports tests, most hybrid cars have better fuel economy than their gas-only counterparts “ (Barett, “The Difference Between Gas and Hybrid Vehicles”). This is obvious if we compare between a hybrid and gasoline cars which have the same name: the hybrid Honda civic average efficiency is 40 MPG while the standard Honda civic average efficiency is 29 MPG, the hybrid Hyundai sonata average efficiency is 33 MPG while the standard Hyundai sonata average efficiency is 27 MPG, and the hybrid Ford fusion average efficiency is 34 MPG while the standard Ford fusion average efficiency is 24 MPG (Barett) [average efficiency is the average between the car efficiency in city and its efficiency in highway
Today's hybrids come in many different varieties such as mild or full and series or parallel. Mild hybrids require the use of an electric motor to assist the gas engine when extra power is needed. It can only move from the stopped position if the internal combustion engine is engaged. The mild hybrid can be broken down into 3 sub-systems. The Start/Stop system, which is also called a micro hybrid, will shut off the engine when the car would normally be idling and instantly restart the engine when pressure is applied to the accelerator. This type of system only increases fuel efficiency by approximately 10 percent and is the most basic of all hybrid vehicles.
The future American commuter will undoubtedly have to transition from the use of fossil fuels to new alternatives due to the diminishing availability of the nation’s oil resources. How will America respond to this upcoming issue? It is difficult to predict which alternative fuel source America will ultimately choose, but with the premier of Nissan’s electric powered Leaf and other companies; such as Tesla Motors and Chevy, with their electric cars ready for market, the electric car may be winning the race to become the new standard for the gasoline alternative. Electric cars resolve long standing environmental issues, but it will need to maneuver around many roadblocks to become a marketable consideration for the general public. The cost of electric cars, currently on the market, makes them an impractical purchase for the average consumer. If cost is not the growing concern in today’s economy which prevents the consumer from considering this option; they may deny the technological advance due to battery storage capabilities and the inadequate infrastructure in place to refuel and provide for them.
(Gilpin, 2014) According to Tesla, the efficiency of electric cars is three times that of the traditional gas engine as most energy is lost through the heating process.(Gilpin, 2014) There are two types of electric vehicles in production today, BEV’s and PHEV’s. BEV’s or Battery electric vehicles run solely on energy stored in a battery that is recharged at stations. These cars have an operating range of 60+ miles and take about 6-8 hours to recharge at a station.(Gilpin, 2014) Those who need to travel more than 60 miles in a day could face problems with this. Those that may need to travel much farther in a day would be wise to choose the PHEV’s or the plug-in hybrid electric vehicle. These vehicles run on both electricity and gasoline. They can run on electricity alone for up to 40 miles until it makes the switch to gasoline acting like a hybrid. This means that after they switch to their hybrid mode, they will use both electric and gasoline powered until they are charged again.(Gilpin, 2014) While in hybrid mode the PHEV’s can run up to 400+ miles before needing a recharge. (Gilpin, 2014) The relevance of electric cars is spiking. Especially in bigger cities that have air quality issues, the demand for transportation with limited emissions will be a huge
Most American cars are not hybrids or fuel-efficient, they are usually big SUV’s or trucks that get eighteen to ten miles per gallon. Most of Hondas, Toyotas, and Hyundai’s get around 20 to 30 miles per gallon, and hybrids get 50 miles per gallon. Peoples demand fuel-efficient cars because oil is i...
Imagine that you’re driving on an open highway in the middle of summer. All you see in front of you is asphalt for miles and miles. The windows are down and your favorite song comes on the radio. You’re behind the wheel of a Tesla Model S, the newest electric car that can go from zero to sixty miles per hour in 2.4 seconds. This will soon be the future of all motor vehicles. Electric cars are beginning to have colossal impacts on our society because of their energy efficiency, performance benefits, and the fact that they are less harmful to the environment. In the near future, electric cars will dominate the road and eventually the planet’s overall need for oil will decrease immensely.
There are two configurations for hybrid cars. The first configuration uses gasoline engine to run a generator. The generator supplies electricity to the motor, which drives the wheels, which allows the gasoline engine to run constantly while achieving optimum fuel efficiency. This thereby minimizes emissions owing to incomplete combustion. A hybrid car with parallel configurations uses both an engine and a motor to drive the wheels depending on driving conditions. "A hybrid car is an automotive equipped with two or more sources of motive energy" (http://www.howstuffworks.com/hybrid-car1.htm).
Today, people use their own personal vehicles to travel more than ever before. Personal transportation is no longer considered a luxury; it is now considered a necessity. The number of cars in the United States has been growing steadily since the 1970s. The number of miles traveled by cars has risen nearly 150 percent, yet the United States population has only grown roughly 40 percent during that time (hybridcars.com, Driving Trends). Although it may seem like we are advancing into the future, in reality, we are moving backwards from the effects these vehicles have on our bodies and the environment. The pollution produced by these vehicles has brought us to the day where we must find other modes of transportation that cause less harm to the world in which we live. Advances in technology have developed hybrid vehicles to try and slow down the amount of pollution. Driving a hybrid vehicle, instead of a conventional gas powered vehicle, can reduce the amount of pollution that affects our lives and the environment around us.
The electric car has been around since the 1830s, eventually transitioning to a practical transportation choice in the late 1800s after improvements in the storage capacity of batteries. The electric car was at the peak of its popularity in the early 1990s. However, its popularity was short-lived; by 1935 the electric car had become a rarity, being replaced by the gas-powered vehicles. Reasons for the change being that the electric car could not travel long distances without recharging due to the limited storage capacities of batteries, it was faster to fuel a gas car than recharge an electric car, and finally, the mass production of the gas car lowered its price significantly compared to the electric car. Present day, the conventional gas powered vehicle is still preferred over electric cars, but advances in hydrogen fuel cell technology are making the option of owning a hydrogen fuel cell powered car more of a possibility as well as highlighting the benefits of other electric cars. In the following paragraphs the operation of the Ballard fuel cell is explained, the challenges with implementing a fuel cell system is discussed and lastly, the possible social and environmental effects of electric cars are explored.
In this case study I will be discussing advantages and disadvantages of electric cars. Electric cars are cars that are powered by electricity. Electric vehicles are an important part of cutting emissions and reducing global warming. The battery of an electric car stores electrical energy. The electric motor is coupled to the wheels through gears; it converts 59-60% of electrical energy into the wheels. The battery runs the motor which allows the car to move. Electric cars are necessary as they will save money, because electricity is cheaper than gas. Also electric vehicles will help reduce global warming and pollution. However, some people say that electric cars still have environmental costs. The electricity used to recharge EV batteries has to come from somewhere in the world, and now, most electricity is generated by burning fossil fuels. Although electric vehicles are classified as green cars, purists will not appreciate the toxicity of the batteries.
Environmentally Friendly Electric vehicles are today’s zero-emission vehicles. They have no tailpipes and emit no pollutants. Instead of gasoline from oil refineries, electric vehicles get their “fuel” from electric power stations. Although power plants using fossil fuels do have emissions, power plant emissions generated for electric vehicle use are typically much lower than emissions from the comparable use of gasoline-powered cars. For power plants using renewable energy sources like wind, solar and hydropower, no air pollution is created.
Most people today fill up their car with different qualities of petrol, because that's what the average car takes. They don't usually consider an alternative for the petrol that they load into their cars. Although petrol is widely used, it is not the only source for a car to get its power from; diesel and electricity are alternatives to the general petrol used by most cars. Although different from each other, diesel and electricity are alternatives to the average gasoline received at a gas station. Diesel is a more concentrated type of fuel that is usually used by big automobiles because they require a lot of power in a little amount of time. Electricity is a method that uses the power of batteries to produce a low horsepower but, nevertheless fast automobile. Electric cars are generally created to be soundless and environment friendly. The purpose of this paper is to classify and educate the reader of the different types of fuel available for an automobile to use: petrol, diesel, and electricity. The general petrol, used by most people, is usually the only type of fuel accepted on the average car in the United States today.
There is no doubt that electric cars are the most appealing from of transportation in the world. They provide two of the most important key points of good transportation: reliable and efficient. They are reliable due to their simplicity of their power trains and the advancement of technology they have. They are efficient because they don't use any gasoline and because their motors can pass the zero-emission standard. Even though they may seem like a boring form of transportation, they offer good features that help keep the Earth's air clean and they help reduce pollution.
...o an electric outlet to recharge the vehicle while it is parked. One great thing about this hybrid is the ability to travel in all electric mode for most short trips. This conserves the gas in the gasoline engine for longer drives. This feature helps boost fuel economy into 100 mpg territory. Not only is the Volt a plug-in hybrid, but so are the Ford Fusion Energi, Toyota Prius, and Honda Accord.
