Electric cars are vehicles that derive their power from electric motors. Many people may think they are a relatively new invention, when in fact, some of the first cars were produced and powered by electric motors which are powered by batteries. The electric vehicles were withdrawn from the market.
They are more enviormental friendly than combustion engines. They are also very energy efficient. In fact, 75 percent of the energy stored in a battery reaches the wheels of a car, while only 20 percent of the chemical energy derived from gasoline is used by the wheels in an internal combustion engine.
Another advantage of electric cars that can provide power to the speed of a motor. This ensures a high performance acceleration of electric vehicles.
The main factor that determines the cost and performance of electric cars are the batteries. Today, advances in technology of electric cars have been a number of battery types, including advanced lead acid batteries, lithium polymer and nickel metal hydride batteries. However, even if an electric motor is extremely efficient, the capacity of the batteries is still very limited. For example, the best batteries can store only a fraction of the energy of a gallon of gasoline in the same volume. The apparent solution to this is recharging. However, the battery can take a long time.
Electric cars still have a long way to go before they reach the mainstream market. Continues to improve technology and innovations are being introduced constantly. Currently, hybrid vehicles, as gasoline-electric hybrids are enjoying considerable success. With the continued advancement of technology for electric vehicles, it may not be long before it becomes more efficient and powerful electric cars, and this time it is probably in the market for good.
