New Electric Motor
Source - IEEE Spectrum

The electric car is one of the technological wonders that the century has produced. It has challenged the way we look at automobiles and apply standard technology to give owners a new way to drive and own a car. For a long time, man has relied on the internal combustion engine for all his automobile needs. This engine, which runs on gasoline principally, has dominated the world of automobiles until recently.

In these few years, the trend has begun to change. Now, people are looking for electric cars. The reason is simple – they want a cheaper way to drive. No more expensive gasoline. Some also want to have a cleaner car – one that produces less smoke.

The electric car has all the parts of a regular gasoline car except one thing – it has no internal combustion engine. This means no gasoline. Instead of a gasoline engine, it preferably has a motor that powers it to move. A set of batteries powers this motor. The batteries are powered by been arranged in a row. Their abilities combined to produce enough current for the car to move as the vehicle moves the power issued up. The batteries could be recharged after the car has made some miles.

Unlike conventional vehicles, the battery will not have to be recharged so frequently. It may take the car up to about 1200 miles before it needs a recharge. For city driving, this may be about a week or two.

Today, electric cars can make about 90 miles an hour, making them comparable to any mid-sized sedan that you can find. With time, this speed will increase, and the batteries will have a longer life.

Electric cars and the environment

Electric engines impact the environment both directly and indirectly at a ultra macro level. It depends on how you need to perceive the situation and how much power you need. From the individual standpoint, electric vehicles do not require gasoline to run, which leads to cars with no emissions populating our expressways and cities. While this presents a new problem with the additional burden of electricity production, it alleviates the strain from millions of cars in densely populated regions putting toxins into the air (fig. 5).

Note: The MPG (miles per gallon) values listed for each region is the combined highway fuel economy rating of a gasoline vehicle. It may have global warming equivalent to driving an E.V. Regional global warming emissions ratings are based on 2012 power plant data in the EPA’s grid 2015 database. Comparisons include gasoline and electricity fuel production emissions. The 58 MPG U.S. average is a sales-weighted average based on where E.V.’s were sold in 2014. From a big-scale perspective, there are several benefits to the rise of electric cars.

Conclusion

The electric engine changes history in the same way that the steam-powered engine and printing press redefined progress. While the electric engine isn’t paving new grounds in the same vein as these inventions, it opens up a new segment of the transportation industry that focuses on style and performance, and external impact. While the electric engine should not be reforming the world due to introducing a new invention or creating a new marketplace, it’s redefining how we as a society, define progress. If nought else is to come from the advancements with the electric engine, at the very least, we can tell that our community has moved forward with our awareness of our environmental impact. This is the new explanation of progress, as defined by the electric engine.

Direct current (D.C.)

The continuous current refers to a constant, unidirectional electric flow. Furthermore, the voltage hold on to the polarity in time. On batteries, it’s marked which the positive and negative poles are. These use the constant potential difference to proced a current all the time in the same direction. Additionally, to batteries, fuel cells, and solar ones, the sliding between specific materials can produce direct current.

Alternating current (A.C.)

The logic alternating current defines a type of electricity characterized by voltage and current that vary concerning time (fig. 1). As the voltage and current of an A.C. signal change, they most often follow a sine wave pattern. required to the waveform being a sine wave, the voltage and current alternate between a positive and negative polarity when viewed all time. The sine wave shape of A.C. signals is due to how the electricity is generated.

Another term you may hear when discussing A.C. electricity is frequency. The frequency of the signal is the few complete. wave cycles completed during one second. Frequency is measured in Hertz (Hz), and in the U.S., the standard power-line frequency is 60 Hz. It means that the A.C. signal oscillates at a rate of 60 complete back-forth cycles each second.

How charging work?

You can charge an electric car by plugging it into a public charging station or a home charging unit. There’s plenty of charging stations around the U.S. to stay fully charged while you’re out and about. But to get the best deal for setting at home, it’s essential to get the right E.V. electricity tariff. You can spend cheap charging and save more money on your bill.

Which types of electric vehicles are there?

There are several different types of electric cars (E.V.). Some run purely on electricity. These are called real electric vehicles. Some can be run on petrol or diesel, and these are called hybrid electric cars.

  • Plug-in electric – the car runs purely on electricity and gets all their power when they’re plugged in to charge. They don’t want petrol or diesel to run, so they don’t produce any emissions like classic cars.
  • Plug-in hybrid – These mainly run on electricity and have a traditional fuel engine so you can use petrol or diesel. If you run out of charge, the vehicle will switch to using fuel. When it’s running on power, these cars will produce emissions, but they won’t when they’re running on electricity. Plug-in hybrids can be plugged into an electricity source to recharge their batteries.
  • Hybrid electric runs mainly on fuel like diesel or petrol but has an electric battery also recharged through regenerative braking. These give you a switch between using your fuel engine and using ‘E.V.’ mode at the touch of a button. These cars can’t be plugged into an electricity source and rely on petrol or diesel for energy.
