The Physics Behind The Electric Vehicle - 1560 Words

The Physics behind the Electric Vehicle It has been estimated that there will be approximately 1200 million motor vehicles by the year 2020. That is almost twice the number of cars that are already traveling on our busy roads. Due to this ever increasing vehicle population, the demand for fuel will continue to increase as well. With the depleting supply of oil already an issue for the U.S. especially, there is a growing interest in alternative energy fuels that can be used to power motor vehicles. Electric vehicles (EV) are one of the cleanest and most environmentally friendly cars available at this point in time. By definition, an electric car is an automobile that is propelled by one or more electric motors, using electrical energy stored in rechargeable or another energy storage device. The electric motors used in these cars gives off instant torque, creating strong and smooth acceleration. Some of the models of EVs have an electric motor for each wheel. Having these four motors not only allows for better propulsion, but also for the use of braking and changing the kinetic energy back into chemical energy in the batteries. The traction that the car gets is also increased with each wheel driving. In some of the EV models the electric motors can be mounted directly inside the mounting for the wheel, which enables a loss of all the moving parts between the motor and the wheel. When there is no axle, differential, or transmission, the EVs have less drivetrainShow MoreRelatedChallenges Of Li Technology899 Words   |  4 Pagesto answer the question of â€Å"how a LIB works† from a physical point of view. The analysis of electron migration is as vast and multi-dimensional as the lithium ion migration however, due to the detailed discussion of such migrations in any modern physics book (mainly the impact of fermi levels on the electron conductivity and mobility), I shall avoid analyzing this concept entirely. The lithium ions behavior was discussed sin ce it is lesser known than the electrons behavior.

As the push for more economic and environmentally friendly modes of transportation expands into plug-in hybrids and fully electric vehicles, the sustainability of our electric grid will come under greater scrutiny. According to a report from the Government Accountability Office, 70% of electric power in the United States comes from natural gas and coal (Johnson). Moreover, 50% of the power generated from fossil fuels comes from plants built before the CleanRead MoreFixing a Car772 Words   |  3 Pagesdifferent types of mechanics there are now. Although the blueprint for the modern automobile was perfected in Germany and France in the late 1800s, the very first self-propelled road vehicle was a military tractor invented by French engineer and mechanic, Nicolas Joseph Cugnot, in 1769. Cugnot used a steam engine to power his vehicle. The military tractor was used by the French Army to haul artillery at speeds of 2  ½ miles per hour, resting only on three wheels. This tractor had to stop every ten to fifteenRead Moreâ€Å"It Is Not Knowledge, But The Act Of Learning, Not Possession1246 Words   |  5 PagesMaster’s Program at the prestigious Clemson University. My mother, a Ph.D. in English Literature, inculcated in me the values and importance of research and giving back to the society through the same. I always excelled in academics but somehow lagged behind in Mathematics till the time I started playing Chess. The great game of Chess fostered an admiration towards algorithms and made me realize the importance of Mathematics in our daily lives.

For example, there are many events for renewable energy or eco-friendly technology in response to the ever growing threat of global warming. These events such as wind power or electric vehicle would be considered build events as they require hands on experience to build well thought-out designs. On the other hand, there are test events where teams of two heavily research on a specific topic such as astronomy or hydrogeology and takeRead MoreThe Fuel Of The Future1374 Words   |  6 Pagesfuture.
