Discover The Latest Developments In Electric Cars

electric car
Cars pollute, kill the planet and generally are not that green are they not? Here is the latest news from the world of the eco-friendly electric cars trying to prove the car hater wrong. The limited edition Micro-Vett electric 500 is an electric, eco version of the famous Fiat 500. This little green-mobile has a maximum speed of 60mph, a range of 70 miles, and takes 6-8 hours to charge.

Transmission is manual 5-speed but there is an automatic option. It weighs around 1050kg, has four seats, and standard kit includes a radio, CD, MP2 player, Bluetooth and USB, air con, remote central locking, ABS with EBD, 15-inch alloy wheels, drivers airbag, drivers knee airbag, passenger and window airbags. You can also pay extra if you want auto climate control, an electric sunroof, reverse parking sensors, 16-inch alloy wheels, and a metallic paint finish to your motor. As with many electric cars price unfortunately is on application. But if you have to ask, you clearly cannot afford.

Lotus introduces an electric car that ROARS! The wonders of modern technology, a car that glides seamlessly along with hardly any noise at all. Well that is great if you are the driver or the passenger, but the quiet hybrid or electric cars of today are not so good for pedestrians as people simply do not hear them coming. Lotus has decided to create a technology to bring that oh so thrilling sound, the roar of a well tuned engine, to eco conscious drivers.

The car manufacturer explains that its safe and sound hybrid technology simulates the growl of a combustion engine, making it instantly recognisable that the vehicle is in motion. It has already put the system into a Toyota Prius, which is one of the most popular hybrid cars on the market. The system produces a pitch and frequency designed to help pedestrians identify the speed and distance of the car. Lotus claim their technology increases pedestrian safety, while retaining the environmental benefits of electric cars.

Shown off at the 2008 motor show, the Lighting car is designed to turn all the heads. Why because it is fast and it is electric. The company claimed the Lightning GTS, which is built in the UK, claims the Lightning can hit 60mph (97kmph) in under four seconds. Instead of one single motor, each wheel has its own giving the most effective power.

Special batteries are used to give the car the power when it needs it rather than a constant speed and you will be able to do a fast charge in around 10 minutes to get you back on the road. The CEO of the company said they are trying to change the perception of what people expect from electric cars. The car will cost around 120,000GBP when it goes on sale so it is up against some real supercar competition.

Hybrid Electric Car: A Promising Technology for a Promising Future for the Environment

electric car
A hybrid-electric vehicle, or HEV, combines an electrical energy storage system with an occupied means of generating electrical energy, usually through the consumption of some type of fuel. Each type of HEV has its own operating quality and chosen design practices, as well as advantages and disadvantages.

The development of interior ignition engine vehicles, especially in automobiles, is one of the supreme achievements of modern technology as a new rising energy saving and environment -friendly vehicle, that is why the hybrid-electric vehicles were created to give convenience to every human.

In the process of creating the hybrid electric car, the most important is the energy saving and the environmental protection. Wherein nowadays this are the common problems faced by the society.

Having the hybrid-electric car evolved from the electric car. However, the main disadvantage of the electric car is that it is mainly dependent on the batteries. Therefore, has limited range.

First of all, the hybrid electric car was supposed to be an electric vehicle with batteries for power storage and is also equipped with an on-board heat engine-powered generator. This means that this type of hybrid has an extended range.

The heat engine power and the battery power are specifically intended as an important scheme that constantly modulates the excess between the heat engine and the battery power systems. This will also depend on the driving schedule.

Since the beginning of the use of automobiles, electric cars have been already recognized and conceptualized. Even though the electric power train is better in various aspects, as an energy source, the battery was unequal to the superior-energy content, easiness in terms of the handling, and inexpensive and profuse supplies of motor fuel.

Now, it has almost been a century since the electric car has been popularly discussed, but recent developments in the HEV technology and the growing concerns for the environment has revived the drive for an HEV and this has become a realization today.

We can consider the personal means of transportation as a very important bond in the economic chain of current modern societies and that a private vehicle appears to be the popular choice.

Electric vehicles are more energy efficient than the contemporary vehicles wherein the electric vehicles operates at approximately 46 percent of effectiveness, while a contemporary vehicle operates at about 18 percent only.

There are studies that generally concludes that electric cars with batteries are approximately 10 to 30 percent more efficient with energy than the usual gasoline cars, depending on the exact assumptions of the vehicles energy usage and energy chain efficiency.

Certainly, the comparisons of the electric vehicles and the conventional vehicles are comparisons between an extremely developed power system that is nearly in the end of its research and development, and the innovative power system in the beginning stages of the development wherein important development can be expected as the new technology evolves.

Furthermore, the advantages of electric powered modes of transportation extends beyond the true outlook of economizing energy. Electric generation plants can use substitute fuels that are not adaptable to portable power systems.

Electric vehicles are the definitive alternative fuel vehicles because their power is taken from the source fuels utilized to produce electricity. Aside from that, the flexibility of the fuel alone can offer important useful and economic advantages especially in relation to a variety of energy resources.

The electric car is truly a promising technology that could transform one's means of transportation into a far more environmentally type of commodity. Through this innovation emission controls become more important, effective and economically beneficial.

Top 7 Disadvantages of Electric Cars

electric car
Soaring gas prices and environmental concerns, electric cars are becoming popular as an answer to some of the problems of the auto industry. However, do electric cars have a spotless reputation?

The following are their disadvantages of EVs voiced for some time now.

1. Charging Woes: Electric powered vehicles require charging stations, and for people to travel long distances there needs to be a network of such stations located strategically. Also recharging of batteries often takes about 3 hours, which nowhere matches efficiency of a gas refuel. And of course there's the charging equipment you need to carry along.

2. Travelling distance (Range): The cars can travel only about a 100 miles on an average, and on a single charge. The technology of Chrysler's proposed EVs is supposed to have the cars run longer, though.

3. Lack of power: In general electric cars are still behind gas powered vehicles in their ability to to accelerate and climb quickly.

4. Overloaded batteries: At the heart of electric automobiles are the car's batteries. At the same time, as all other car accessories viz. radios, car air conditioners, etc. use up electric power from batteries, they'd drain quickly. And recharging them takes time!

5. They are expensive: Batteries that power these cars are a costly affair. Consider this: The promising and long-lasting lithium-ion batteries cost about US$10,000 each, which for the most part make these cars expensive. And if the batteries last only about 4 years, they could add to the maintenance costs.

6. The cause pollution: Yes, the 'clean & green' electric cars cause pollution too, albeit indirectly. While themselves being clean, there are toxic elements within batteries and which could spew toxic fumes. Further, the car's engines are powered by electricity, and all of which isn't generated from renewable energy sources. Which means electric power production per se entails pollution.

7. They're Heavy: Batteries are what makes these vehicles heavy. A battery pack of an average electric car can weigh up to a 1,000 pounds or 450 kg (approx.) This a disadvantage because weight puts pressure on batteries and they drain out faster.

While the prospect of electric vehicles seems promising, electric vehicles don't appear to be a pancea and have their own share of shortcomings. Consequently, a purchase decision in favor of EVs or hybrids might not be all that simple.
