How Electric Cars Work???

Question

Electric cars are something that show up in the news all the time. There are several reasons for the continuing interest in these vehicles:

Electric cars create less pollution than gasoline-powered cars, so they are an environmentally friendly alternative to gasoline-powered vehicles (especially in cities).

Any news story about hybrid cars usually talks about electric cars as well.

Vehicles powered by fuel cells are electric cars, and fuel cells are getting a lot of attention right now in the news.

So why don't we use eletic car?

Answer 1

We don't use electric cars because battery technology is too primitive to give them the range of gas cars.  And the performance is even worse in cold places.  Plus all this flawed technology is very expensive.

Answer 2

They work by storing energy in the battery and then using it to power a highly efficient electric motor.

We're moving rapidly toward this technology.  Essentially every major auto maker is working on plug-in hybrids and/or fully electric cars.  Some smaller automakers are beating them to the punch too.  The first affordable highway speed EV is coming out in July.

Answer 3

Cars that are in the news don't necessarily exist, and there are neither electric cars nor fuel-cell cars in production at present.  It's doubtful that they will be in the future except for the most specialized applications.  Most of what you've been seeing consists of wishful thinking and attempts to raise money.  I suspect that a significant percentage of the electric car schemes that have been advertised recently are fraudulent.  

I am growing rather suspicious of Tesla Motors right now: their fifteen-month waiting period for delivery strikes me as just a bit too long.  It'll be interesting to see what happens to them next year.

Answer 4

An electric car is a car powered by an electric motor rather than a gasoline engine.

From the outside, you would probably have no idea that a car is electric. In most cases, electric cars are created by converting a gasoline-powered car, and in that case it is impossible to tell. When you drive an electric car, often the only thing that clues you in to its true nature is the fact that it is nearly silent.

Under the hood, there are a lot of differences between gasoline and electric cars:

The gasoline engine is replaced by an electric motor.

The electric motor gets its power from a controller.

The controller gets its power from an array of rechargeable batteries.

A gasoline engine, with its fuel lines, exhaust pipes, coolant hoses and intake manifold, tends to look like a plumbing project. An electric car is definitely a wiring project.
