Article: How An Electric Car Works
With the many ill effects of the combustion in cars, we now have an alternative–electric cars.
The electric car (EC) was designed as an alternative automobile that can run on an electric motor. The electricity is contained in a battery, which functions unlike the conventional car battery that is used only as a starter.
These electricity-powered cars used to be popular in the late-19th century and early 20th century. However, the develeopments in the internal combustion engine technology combined with the mass production of cheaper models of gasoline-powered cars led to the decline of the EC.
For all the energy required to propel a vehicle, not all of it makes it to the wheels. Some of it is lost to friction and heat. Vehicle inefficiency can be classified into two categories of losses: road-load and energy conversion. At Tesla, careful attention is given to both to achieve the maximum range. The Tesla Roadster leverages both an incredible electric powertrain and an engineer?s obsession with efficiency to be the most efficient production sports car on the market today.
These electric cars feature motors like regular cars, except for the function of the battery. The batteries used in electric cars may vary in design. Some use the lead-acid type battery, lithium ion, molten salt, zinc-air, or those nickel-based designs.
The limitation of electric cars stems from the fact that its battery life could not last long, unlike if you use fuel for your car. They do not run very fast either. They are best for city-driving where you usually just travel short distances.
