Electric Cars v/s Gasoline Cars
In the making of an electric car, a few parts get replaced from a conventional gasoline driven car. Firstly, the internal combustion engine, which is replaced by an electric motor. It gets its power from a controller which is further connected to an array of rechargeable batteries. On a higher level of abstraction, a gasoline car might look like a plumbing project with fuel lines, exhaust pipes, hoses etc. while an electric car may look more like a wiring project. The difference in sound levels might be oblivious to a person standing outside, but the one sitting inside would notice that the electric car is almost silent, even while running. The electric parts are supplemented by little changes of the car like the fuel gauge being replaced by a voltmeter, the engine vacuum used in power brakes being replaced by a vacuum pump, the manual transmission being replaced by a switch etc. Though these designs may vary from vendor to vendor and car to car, the first three parts discussed are essential to any electric car. Apart from these, there are a few subtle differences which can be drawn as in the figure below.
Comparing the two solely on initial pricing would always give gasoline cars an upper hand. On closely seeing the performance of electric cars, it is observed that they offer an advantage of up to 30% on each kilometer driven. And each battery pack which usually lasts around 2 to 3 years is capable of running 25,000 kilometers.
