Automotive Update

By definition, an electric vehicle is one that is driven by an electric motor instead of a gasoline engine. It is powered by a controller depending on the driver’s pressure on the accelerator pedal. The motor of the electric car uses energy stored in rechargeable battery and can usually travel about 100 miles between charges.

As many people are pushing for an environmentally friendly vehicle, the use of electric vehicles is growing. In fact, JD Powers and Associates predicts that if electric cars in 2010 represent only 2.2% of vehicles on the road, that by 2020 this figure of 7.3% and a study by Consumer Reports shows that 39% survey, people think about buying an electric vehicle as an investment in your next car.

Perhaps one of the factors contributing to this growth is that the EV advocates promote the use of lithium-ion batteries as an energy source. By replacing the traditional gasoline engine, the vehicles require less maintenance and no need to change oil or other filters associated with vehicle maintenance. However, there is still some debate as to whether lithium battery electric vehicle is the answer.

For example, lithium batteries have less effect on the environment than their traditional counterparts, but to function properly lithium batteries require a large amount of copper and aluminum. As these metals are necessary to produce the anode, cathode, wire management system and the battery, it means more exploitation of these elements means that an additional burden on the environment compared to the costs energy and use more chemicals and water. In addition, a 2008 study cited by Meridian International France estimates that lithium is less available than previously thought, with most lithium in ecologically unstable world. If we sacrifice the parts of the world such as tropical forests and rainforests to build lithium batteries, then we have exchanged one problem for another. In addition, as an American that trade as our dependence on oil from the Middle East to a dependence on imported batteries.

The effects on the ecology of the mind, researchers at the launch of Switzerland, the rebellion of technology are tests to see if the lithium-ion batteries could be replaced by a zinc-air battery. Their studies show that zinc-air battery, while the energy a little less dense, it is much cheaper (one fifth of the cost) to produce and easier to find than lithium, that ultimately it more widely available. An additional advantage of zinc-air battery that is safer to use than lithium, because it does not require expensive safety precautions heat. Today, zinc is used in a variety of batteries, but none of them are rechargeable.

Lithium ion or zinc-air batteries are alternatives to electric vehicles. And when it comes to the benefits of electric vehicles is still much to learn and use to explore. Yes, the electric vehicle is an excellent response to pollution caused by the gasoline engine, but there are many considerations before it considers the source of lithium battery choice.
