Abstract—Electric vehicle (EV) have obtain a positive response from the people due to the environmental-friendly factors. However, Electric vehicle powered has not yet being commercially because of power efficient, reliability and also high production cost.
I. LITERATURE REVIEW:
Electric Vehicles are zero emissions and higher energy efficiency much environmental friendly than the conventional petrol and diesel vehicle. However, the electric vehicle has a smaller energy available compared to conventional vehicle. Therefore, electric vehicle deign to against aerodynamic drag must be reduced to a very low level to keep the same performance as conventional vehicle. Aerodynamic drag force and drag reduction is a crucial task

DESIGN/RESEARCH QUESTIONS:
Design Questions:
1. Are Electric vehicles safe?
2. Do electric vehicles pollute?
3. Cost of operating an electric vehicle?

Research Questions:
How to reduce the aerodynamic drag?
There are many methods to reduce a vehicle air drag. Normally it is a focus of shape, the design of the bodywork can make a vehicle more aerodynamic.

III. RATIONALE:
To mitigate environmental problem, especially the greenhouse gas from conventional vehicle, research and development is conducted throughout the world on vehicle that run on new energies. The electric vehicle is significant for the future development to the community.

IV. CONTEXT IN CURRENT BODY OF KNOWLEDGE:
Individual components where air drag and air swirls are forming, like the underbody, engine compartment and the wheel houses for example, vehicle designer are trying to harmonies aerodynamics with comfort and looks in this

Though the electric car itself does not burn fuel, most power plants use "fossil" fuels to generate electricity, so we must consider the pollution created at the power plant. Another issue that is rarely addressed is the fact that most electric cars use batteries which themselves have the potential to pollute if they are not disposed of correctly. In many cases, batteries, while they are being charged, gives off gasses, which can vary depending upon the type of battery. This can be hydrogen and oxygen or sulfur fumes or other gases. Hydrogen and Oxygen themselves are not considered pollution of course; however the mixture can be explosive if they are allowed to reform water. Another type of pollution that may be of concern is the electro-magnetic emissions that some people feel can cause various human ailments. Electric motors can be shielded with special alloys, such as a highly tempered copper/nickel alloy, creating a type of Faraday cage, however this adds weight to the vehicle and it is not conclusive that all emissions can be

    Electric engines must be in a good condition in order for it to do its job. Electric engines are eco-friendly they just need good quality batteries for it to work. Batteries for electric engines depends for the speed the driver needs. The electric can use solar pads so it could be charged, but if there no heat the electric engines can be charged by cables like charging an ordinary battery. Electric engines will help remove pollution because first of all there is no smoke because they are just electric engines.…

    Electric vehicles convert about 59%-62% of the electrical energy to power at the wheels. Although the power plants producing the electricity may emit tailpipe pollutants, they do not emit them. Electricity from nuclear, solar, or wind powered plants causes no air pollutants. Therefore, they can be…

    Of the choices listed, the plug-in vehicle, is the best option for an alternative to standard petroleum vehicles. There are many reasons the plug-in is best, but the main reasons are; most people are not ready to transition to a pure electric vehicle yet; plug-in vehicles are very efficient; and plug-in vehicles reduce pollution.…

    The second type, PHEV uses either motor or electric motor to give energy. As either kind of motor is used inefficiently, this kind of cars are not so much common. The third one, CHEV is actually the most efficient of the three. When the engine has just been started, CHEV will use motor to speed up. And then after the car has reached the average speed, it will let the electric motor to give energy, and use motor to charge the battery.…

    People have been debating on the environmental benefits on solar panels because there is some pollution involved. Solar energy does not produce any pollution directly like burning coal or other fossil fuels does. However, the panels themselves use some hazardous materials. According to Maehlum “Some manufacturing processes are associated with greenhouse gas emissions. Nitrogen trifluoride and sulfur hexafluoride has been traced back to the production of solar panels.” (Maehlum 1).…

    To begin with, nuclear energy has several major advantages. Not only a large amount of energy can be produced with only a tiny amount of energy input to the power generator, but the maintenance cost is low also. Moreover, unlike fossil fuel, it will not cause serious air pollution. However, after the two serious nuclear…

    Practicality and affordability are arguably the most important features for the consumer. The alternative to a non-fossil fuel powered vehicle, without going full electric is the hydrogen fuel cell car. Hydrogen fuel cell cars have a pump and go method of operation, moreover, they are not plagued by battery range and lifespan setbacks that electric cars are. Although, hydrogen fuel cell vehicles are plagued by a lack of infrastructure as electric cars are, as well as, higher price tags compared to their internal combustion engine rivals. These setbacks may be overcome just the same as with electric cars over time, leaving the benefits much greater than a solely electric powered car.…

    With fossil fuels causing harm to our environment, it is important to search for alternatives that will benefit our earth. Alternative energy is energy that is widely available and environment friendly. These alternative energy sources do not consume fossil fuels; instead they are nuclear, solar, wind or hydroelectrically powered. These energy forms are more environmentally friendly because they cause little or no pollution. It is important to know the different types of alternative energy because it could help benefit our environment in the future.…

    Electric cars are better than gasoline cars. Imagine the world without the harmful pollution from burning fuels that produce dangerous fumes--a world where tremendously high gas prices no longer remain, and where we don’t completely deplete the world’s scarce supply of fossil fuels. We need to prevent smog and other dangerous gases like it. Save the environment; get a battery powered…
