Unlike Hybrid cars electric cars don't have a gasoline engine for charging the battery and the drive system is totally electric, and an electric motor provides the propulsion for the car...
Another advantage is that because of this, the motor provides more torque than a gasoline engine can, which means quicker acceleration, so you will notice a breathtaking difference in the performance of the car compared to a gasoline car...
Other benefits are zero pollution, because the car does not burn fossil fuel, and lower running costs, because the component count is less, no fuel and air filters, spark plugs, and oils of various types...
Even though charging the car has to be done via the mains electricity system, with coal burning power stations providing the power...
The amount of carbon released into the atmosphere is much lower than for an equivalent mileage travelled in a gasoline car, because electric cars are 3 to 5 times more efficient...
Now looking inside the car there is an electric motor, which provides drive to the wheels, a battery pack which provides energy for the motor, a controller which via the accelerator pedal controls the flow of electricity to the electric motor...
The battery pack is usually lithium ion because of the weight of lithium, it being the lightest metal available and also the most reactive so that power to weight is greatly improved over older types of batteries such as Nickel metal hydride...
The battery can usually be recharged generally overnight, this is done via a mains cord which simply plugs in to your mains power outlet and charges the car although there are quick chargers becoming available for some models of car...
Also there are newer types of car which provide an internal charger set like the Chevy Volt, and this runs after the battery pack depletes to a preset level.
This is a small gasoline engine which allows the car to be completely electrically driven, while providing the long distance travel many people require of their cars...
This gives the best of both worlds and may become the standard type of electric car in the near term, unless there are some major improvements in battery performance and may be how electric cars work in the near future...
