EV SUPPORTER, NOT BECAUSE I THINK I SAVE THE PLANET, BUT BECAUSE I FIND THE EV MUCH MORE ENJOYABLE TO DRIVE.
WHY TO CHOOSE EV:The EV is the car everyone chooses first. The reason is obvious; it is simply a much better car to drive. The noiseless engine let you hear the wind blowing and the birds singing, or you can turn on music and hear it without any disturbing engine in the background. The gearless drivetrain gives a unique smoothness, and the acceleration is just superb.
HISTORY OF ELECTRIC VEHICLES :
Timeline: History of the Electric Car
Not an invention of modern times, the electric car has a long and storied history. Travel back in time as we explore the history of the electric car.
1828 — 1830
First Small-Scale Electric Cars
Horse and buggies are the primary mode of transportation, but innovators in Hungary, the Netherlands and the U.S. think to the future, creating some of the first small-scale electric cars.
First Crude Electric Vehicle Is Developed
Around 1832, Robert Anderson develops the first crude electric vehicle, but it isn’t until the 1870s or later that electric cars become practical. Pictured here is an electric vehicle built by an English inventor in 1884.
1889 — 1891
First Electric Vehicle Debuts in U.S.
William Morrison, from Des Moines, Iowa, creates the first successful electric vehicle in the U.S. His car is little more than an electrified wagon, but it sparks an interest in electric vehicles. This 1896 advertisement shows how many early electric vehicles were not much different than carriages.
Electric Cars Gain Popularity
Compared to the gas- and steam-powered automobiles at the time, electric cars are quiet, easy to drive and didn’t emit smelly pollutants — quickly becoming popular with urban residents.
WHY ELECTRIC CARS ARE OUR FUTURE:
In fact, first-generation electric vehicles such as the Chevy Volt and Nissan Leaf have failed to gain significant market share in their first two years of availability, and many have concluded that they are not the future of personal transportation, either in the U.S. or elsewhere. Nevertheless, despite this widespread skepticism, other carmakers are rolling out new electric vehicles on a regular basis, including Ford, Tesla, Mitsubishi, Volvo, and BMW, among others.
Why? Because a careful analysis reveals that there are fundamental reasons that will drive manufacturers and consumers inevitably to electric vehicles in the years ahead, reasons that the public in general is unaware of. So here are a few of the reasons that I have learned that lead me to believe that within 50 years a majority of our cars will be equipped with electric drivetrains.
1.Electric vehicles are inherently more efficient at turning energy into miles driven. Most people do not realize this, but electric drivetrains are much more efficient than internal combustion engine (ICE) drivetrains (about 75% vs 25%, in fact). In fact, there is little hope that ICE drivetrains could ever compete with electric drivetrains in terms of efficiency. Why are ICE drivetrains so inefficient? There are many reasons, including heat losses and inertial losses of various kinds, but ICE’s are also thermodynamic systems with efficiencies limited by the heat cycle they operate under. Engineers have done amazing work in improving the efficiency of gas-powered cars, but they are up against fundamental limits. In contrast, a Nissan Leaf or a Chevy Volt can go about 40 miles on 11 Kilowatt-hours (KWH) of electricity, the energy equivalent of a third of a gallon of gasoline. And since the national average cost per KWH for electricity is only $0.11, this performance translates cost-wise into the equivalent of more than 120 miles per gallon.
2.Electric vehicles are greener than gasoline-powered cars. There are those who have tried to argue otherwise, but the most credible research has shown that most of a vehicle’s carbon production comes during operation rather than production, and electric vehicles that consume only a third as much energy in operation are inherently greener no matter what fuel is used to generate the electricity they use. And electric vehicles powered by electricity from hydro, solar, wind, or nuclear sources produce no carbon in operation.
So in the future, electric drivetrains will probably dominate whatever the energy source. There’s just no other way to get this kind of efficiency gain from an ICE drivetrain.
COUNTRIES USING EV WORLDWIDE :
Electric car use by country varies worldwide, as the adoption of plug-in electric vehicles is affected by consumer demand, market prices and government incentives. Plug-in electric vehicles (PEVs) are generally divided into all-electric or battery electric vehicles (BEVs), that run only on batteries, and plug-in hybrids (PHEVs), that combine battery power with internal combustion engines. The popularity of electric vehicles has been expanding rapidly due to government subsidies, their increased range and lower battery costs, and environmental sensitivity. However, at the end of 2016, the stock of plug-in electric cars represented just a small fraction (0.15%) of the 1.4 billion motor vehicles on the world’s roads.
Global cumulative sales of highway-legal light-duty plug-in vehicles reached 2 million units at the end of 2016,and the 3 million milestone was achieved in November 2017. Sales of light-duty plug-ins achieved a 1.3% market share of new car sales in 2017, up from 0.86% in 2016, and 0.62% in 2015. The global ratio between battery BEVs and PHEVs was 66:34 in 2017, up from 61:39 in 2016, and 59:41 in 2015.
As of December 2017, China had the largest stock of highway legal light-duty plug-ins with over 1.2 million domestically built passengeralso dominates in plug-in electric bus deployment, with its stock reaching 343,500 units in 2016 out of global stock of about 345,000 943,600 light-duty passenger.
THE TECHNICAL EXPLANATION BEHIND EVS AND THEIR SUCCESS, AND WHY DIDN’T SOMEONE THINK OF THEM SOONER?Electric vehicles are on the road to becoming the norm, partly due to their lower associated costs. Almost all major car manufacturers are beginning to make some of their models fully electric. The next phase of land transportation is almost upon us. So how did it happen?
The answer: better technology. Let’s start with the engine, or, in the EV’s case, an induction motor. A gas car’s internal combustion engine (ICE) is much more prone to failure than an EV’s motor, and that’s not surprising considering ICEs have hundreds of moving parts. Induction motors, on the other hand, only have a handful of parts, making them much simpler and easier to repair. The vastly fewer parts in an EV motor make the vehicle more reliable, so the drivetrain has a much lower chance of failure.
After the engine, the force generated then goes through the rest of the transmission, starting with the clutch. The clutch exists in gas cars and allows it to change gears, which are housed in the gear box. Gas cars have anywhere from 6-10 gears to control the different speeds that drivers need to go. The gear box is necessary because ICEs have a very small band of peak efficiency. The RPM needs to be kept within that band for the car to run most efficiently, so the gears constantly have to shift up and down. This creates extra friction and a higher moment of inertia, which means more energy is required to keep everything spinning. Overall, these make gas vehicles much less efficient than EVs.
EVs, on the other hand, only have one driving gear (a step-down transmission) because an electric induction motor is efficient from 0 RPM all the way up to around 6,000 RPM (which a car will never need to go).
By studying all this data we may easily come to a conclusion that EVs are way much more better option in every prospective whether it is comfort or future energy concern.
