Electric Cars vehicles

The Electric Cars are vehicles / automobiles that are propelled by electric motors, using electrical energy stored in batteries or another energy storage device. Electric motors give electric cars instant torque, creating strong and smooth acceleration much more than the usual internal combustion cars.

Electric cars were popular in the late 19th century and early 20th century, until advances in internal combustion engine technology and mass production of cheaper gasoline vehicles led to a decline in the use of electric drive vehicles. The energy crises of the 1970s and 1980s brought a short-lived interest in electric cars, though those cars did not reach mass marketing as today's electric cars experience it. Since the mid-2000s, the production of electric cars is experiencing a renaissance due to advances in battery and power management technologies and concerns about increasingly volatile oil prices and the need to reduce greenhouse gas emissions.

Vantages of Electric Cars Vehicles

Electric cars have several benefits over conventional internal combustion engine automobiles, including

• significant reduction of local air pollution, as they have no tailpipe, and therefore do not emit harmful tailpipe pollutants from the onboard source of power at the point of operation;
• reduced greenhouse gas emissions from the onboard source of power, depending on the fuel and technology used for electricity generation to charge the batteries;
• less dependence on foreign oil, which for the United States and other developed or emerging countries is cause for concern about vulnerability to oil price volatility and supply disruption.

Despite their potential benefits, widespread adoption of electric cars faces several hurdles and limitations. As of 2013, electric cars are significantly more expensive than conventional internal combustion engine vehicles and hybrid electric vehicles due to the additional cost of their lithium-ion battery pack.

However, battery prices are coming down with mass production and are expected to drop further. Other factors discouraging the adoption of electric cars are the lack of public and private recharging infrastructure and the driver's fear of the batteries running out of energy before reaching their destination (range anxiety) due to the limited range of existing electric cars.

Several governments have established policies and economic incentives to overcome existing barriers, promote the sales of electric cars, and fund further development of electric vehicles, more cost-effective battery technology and their components. Several national and local governments have established tax credits, subsidies, and other incentives to reduce the net purchase price of electric cars and other plug-ins.

Maintenance of Electric Cars Vehicles

Electric cars have expensive batteries that must be replaced but otherwise incur very low maintenance costs, particularly in the case of current lithium-based designs.

Running costs of Electric Cars Vehicles 

The cost of charging the battery depends on the price paid per kWh of electricity - which varies with location. As of November 2012, a Nissan Leaf driving 500 mi (800 km) per week is estimated to cost US$600 per year in charging costs.

Future of Electric Cars Vehicles

The future of battery electric vehicles depends primarily upon the cost and availability of batteries with high specific energy, power density, and long life, as all other aspects such as motors, motor controllers, and chargers are fairly mature and cost-competitive with internal combustion engine components. By the year 2020 is estimated the 30% of the cars driving on the road will be battery electric or plug-in hybrid.
Additionally a recent report claims that by 2020 electric cars and other green cars will take a third of the total of global car sales.

It is estimated that there are sufficient lithium reserves to power 4 billion electric cars
