The Electric Battery
An electric car along with all its accessories is powered by its battery. The electric battery drives a controller which is used to run the main electric motor of the car. Cars driven by gasoline and diesel also have batteries, but they are mainly used to start the engine of the vehicle and also power some of its accessories like the radio, television or the air-conditioner. Just like fuel-driven cars need to be reloaded, once they are exhausted of their fuel reserves, the electric car batteries are required to be recharged when they are depleted of their initial power. Therefore, electric batteries need to be strong and enduring in terms of their power and longevity. Till recently, battery manufacturers were yet to invent dependable electric batteries that could bring electric vehicles at par with the fuel-driven cars. However, the production of electric cars have become more affordable in recent times and the main automobile manufacturers are expected to produce such electric cars on a large scale (Lampton, 2011).
First Automobile powered by a Battery
In 1873, R. Davidson of Edinburgh showed that a road vehicle could be driven by an electric battery. He experimented by driving a four-wheeler truck powered by a primary battery made of iron/zinc. After this, in 1881, G. Trouve of France constructed a tricyle, weighing 160 kilograms (350 pounds), which became the first vehicle to be driven with the help of a “secondary Plante battery”. Trouve utilized two customized Siemens motors to drive a huge propelling wheel with the help of two chains which in turn drove the tricycle. The Plante battery helped the motors to develop the strength of 1/10 horsepower which enabled the tricycle to move at a speed of 12 kilometres per hour (7 miles per hour). Later, Trouve demonstrated that electric batteries could be used to drive other forms of vehicles too. During the same year, he experimented by operating a motor boat on the river Sienne which was powered by electric batteries. In the following year (1882), Professors William Ayrton and John Perry of England, also demonstrated the utility of electric batteries in driving transport vehicles. They had also developed a tricycle powered by an electric battery which had a capacity of 1 ? kilowatt hour. This battery consisted of ten Plante type battery cells made up of lead/acid. Apart from this, the tricycle had a direct current (DC) motor having the strength of ? horsepower, which was fitted under the driver’s seat. The electric battery supplied a current of 20 volts to the DC motor which in turn propelled the vehicle. The tricycle could travel at a speed between 16 and 40 kilometers per hour (between 10 and 25 miles an hour), the speed varying according to the type of land terrain traversed. This speed could be regulated by switching the batteries sequentially in series (Westbrook, 2001, pp.9-10). How Electric Car Batteries are Made In the present-day world, the two most popular forms of electric car batteries are the “advanced nickel metal hybride battery (NiMH)” and the “advanced automotive lithium ion (Li-ion) battery”. Majority of these two types of batteries are produced by firms in China, ...Download file to see next pagesRead More

How Flextronics Have Achieved Significant Reductions in Inventory

PCB customers are varied. In most cases, PCB’s are made and sold to low-cost regions such as the Pacific Rim. This PCB are used to produce large quantity electronic components for consumption according to (Pennet.com 2008). However, there has been a shift in the manufacturing industry as most Electronic Manufacturing Services (EMS) prefer to come up with their own end products. This has led to EMS carrying out their own assembling of electronic products. The increased manufacture of electronics has led to increased demand for PCBs. in most cases, large EMS providers have taken the initiative and began manufacturing their own PCB’S.

For a long time, the single-layered PCB’s were the most common as they...

A Small Sports Car as an Investment

The purpose of this report is to determine the “best bang for the buck” if a consumer was looking to purchase a small sports car. A car purchase should be treated as an investment, even though we know that spending money on a vehicle with the high gasoline prices and insurance premiums is probably the worst type of investment money can buy. Therefore, the ultimate purpose is to guide this expenditure in reaping the maximum benefits available.

How Does the US Media Effects Evolve in Singapores Current Media

Lewis and Slade (2000, p. 223) in their critical evaluation of the effects of media communication on the audience argue that media effect is achieved incongruent with social context. Their study recounts the experiment on the influence of television on identity in Singapore indicates that US social values and Singaporean values greatly differ from each other. The sharp differences in program content have a negative influence on the audience because Chinese raised Singaporeans value marriage, social values, and collectivism whereas US social culture involves career, family and the struggle to balance the two. Therefore the question of US media's influence to destabilize Singaporean national identity is limited. This view is emphasi...

How Tomatoes Can Help Your Heart

Whether tomato is a fruit or vegetable? Well, this question can be answered in both ways. Botanically, tomato is a fruit but it is so frequently used as a culinary item all over the world, it is also considered as a vegetable. Long time back, the tomato was considered as fruit and helped the exporters to avoid taxation but 1893 the Supreme Court put an over this dispute by declaring that tomato was a vegetable and since that time onwards, tomatoes were taxed accordingly. Keeping in harmony with this tradition, till date tomatoes are served as entrée and very rarely as dessert. Apart from side dishes, wide array of main course dishes are also prepared from tomatoes and these dishes are regarded considered as lip-smacking cui...

Amending the Constitution: How Hard It Is to Change

However, the purpose of our government is not subjective, and it is not unwritten or buried somewhere in the philosophical musings of a Greek theorist. The purpose of government, specifically our government, as stated by Thomas Jefferson in the Declaration of Independence, is “to secure these [natural] Rights, Governments are instituted among Men, deriving their just powers from the consent of the governed…” Our government exists to protect individual, negative rights that exist outside the common law. Whenever a force, whether in a society or from outside it, threatens the rights of citizens, it is the responsibility of their government to take action and protect them from violations. There are many forces that...
