Electric Cars: Pros and Cons

/ Azuni Blogger / Leave a comment

It’s important to recognize that electric cars are regularly changing and their technology is still evolving when considering electric cars’ pros and cons. More and more car companies are offering electric cars. Electric cars are those that use a rechargeable battery-powered engine in place of a typical gas engine.

What Are the Advantages of Owning an Electric Car?

According to environmentally conscious websites like Earth911 and Energy Sage, there are several notable advantages of owning an electric car including:

  • They are better for the environment
  • Electricity can be a renewable resource, gasoline cannot
  • They require less expensive and less frequent maintenance.
  • They are quieter than gas vehicles
  • There are tax credits available for owners of electric cars
  • There are special highway lanes in some places for electric cars

They Are Better for the Environment

Many car buyers are convinced to switch to an electric car because they are better for the environment. Because fully electric vehicles (not hybrids) don’t use an exhaust system, they have no emissions. Without pumping any fumes into the air like gas engines do, electric cars can help achieve cleaner air and fewer greenhouse gasses.

Electricity Can Be a Renewable Resource, Gasoline Cannot

Electric cars can be powered naturally with renewable resources like solar, wind, and water power. Gasoline, however, is created using oil, which is a natural resource, but not renewable. For those who want to keep the renewable energy flowing even more, having solar panels installed in your home will in-turn power your electric car in your garage.

Electricity is also cheaper than gas. Electric cars typically cost one-third the cost of gas-powered vehicles to run. Many electric vehicles also use regenerative braking to add to the energy the car needs to run, which is completely cost-free.

They Require Less Expensive and Less Frequent Maintenance

Without the use of a gas engine, electric cars don’t need oil. That means no more oil changes. Also, you’ll forgo any other maintenance and repairs associated with a traditional gas engine. Electric cars are typically easier on brakes as well leading to fewer brake replacements, accord to AutoTrader.com.

They Are Quieter Than Gas Vehicles

Electric cars run very quietly, especially when running fully on battery power. In some states, legislators have considered requiring electric cars to have noise makers installed to let pedestrians know they’re coming. According to MYEV.com, the 2019 Jaguar i-Pace electric car adds engine noises to the vehicle when the driver accelerates quickly for the feel of a traditional engine.

There Are Tax Credits Available for Owners of Electric Cars

Original owners of electric cars can receive credit on their tax returns simply for owning a car that’s better for the environment. You’ll need to be aware of the fine print that always accompanies tax situations like this, but you can get as much as $7500 in credit in some states for certain cars. Specific makes and models receive different credit amounts. If you’re interested in learning about what kind of credit you could receive, there are several online resources available.

There Are Special Highway Lanes in Some Places for Electric Cars

Some major highways have HOV (high occupancy vehicle) lanes that can bypass traffic during rush hour. This is known as the carpool lane, but is also available to electric car drivers. Even if your electric car is just carrying you, you’re entitled to use this special lane.

What Are the Disadvantages of Owning an Electric Car?

According to Plugincars.com, there are a few disadvantages of owning an electric car, including:

  • Electric cars have a shorter range than gas-powered cars
  • Recharging the battery takes time
  • They are usually more expensive than gas-powered cars
  • It can sometimes be difficult to find a charging station
  • There aren’t as many model options

Electric Cars Have a Shorter Range than Gas-Powered Cars

Although auto companies are finding more and more ways to make electric cars go further, they still have a shorter range than traditional cars. Usually, an electric car can get between 60 and 100 miles on a full charge. Depending on the fuel efficiency of a car and the size of its gas tank, some can make it up to 400 miles on a tank of gas.

Recharging the Battery Takes Time

Filling up a gas tank might take up to three minutes at the gas station, while recharging the battery of an electric car takes much longer. Depending on the model, an electric car can sometimes take up to 20 hours to fully charge. Newer and more expensive models can charge in as quickly as four hours. However, having a charging station in your garage helps make this more manageable and kits are available to help cut down the charging time.

They Are Usually More Expensive Than Gas-Powered Cars

The fully electric models of specific cars are always more expensive than their gas-powered equivalents. Basic electric models start at around $30,000 with luxury model prices climbing to $80,000 and more. Usually, a car buyer will pay at least $10,000 more for an electric car than they would for the same type of car in a gas model. As technology continues to evolve, this price gap is likely to close.

It Can Sometimes Be Difficult to Find a Charging Station

Some areas have lots of electric vehicle (EV) charging stations in various parking lots and on the sides of the road. This isn’t the case in every city. Road trips can be difficult in electric cars. You can’t take your home charging station with you on the road. More charging stations are popping up around the country as more people are driving electric cars, so this may not be a disadvantage for much longer.

There Aren’t as Many Model Options

Finally, car makers have been building traditional car models for over 100 years, but mass production on electric vehicles as we now know them didn’t start until the ’90s. With less of a history, there just aren’t as many electric models available as there are gas-powered.

There are plenty of advantages to buying an electric car, especially if the health of the environment is important to you. Make sure you don’t miss out on incentives if you do buy one.

How does an Electric Car work ? | Tesla Model S

/

Electric vehicles are making large waves within the vehicle world.

These noise-free, pollution-fre and high-overall performance automobiles are anticipated to make their IC engine opposite numbers out of date by 2025.

This video will unveil the hidden technologies at the back of the Tesla model S which lately became the sector’s quickest accelerating automobile.

We will see how electric powered automobiles have achieved advanced performance by means of studying the technology in the back of the induction motor, inverter Lithium-Ion battery Power source, and, chiefly, the synchronized vehicle mechanism, in a logical step-with the aid of-step Manner. 

The powerhouse of the tesla automobile is an invention made through the first rate scientist Nikola Tesla around 100 Years ago: the induction motor!

The induction Motor has important elements: the stator and the rotor.

You can see the construction details of the motor right here. The rotor is truly a set of carrying out bars short-circuited by way of give up rings. A three-phase AC electricity enter is given to the stator. 

The three-phase alternating contemporary in the coils produces a rotating magnetic field. The tesla motor produces a four-pole Magnetic discipline. This rotating magnetic area that induces present day at the rotor bars to make it turn.

In an induction motor the rotor usually lags at the back of the RMF. An induction motor has neither brushes nor a permanent magnet.

At the equal time it is sturdy and effective. The beauty of an induction motor is that its pace relies upon on the frequency of the AC strength deliver. So simply by way of varying the frequency of the electricity supply, we will be capable of adjust the pressure wheel velocity.

This easy truth makes electric car speed manipulate easy and dependable. The motor Supply is from a variable frequency force, which in turn controls motor speed. The motor pace can range from Zero to 18, 000 rpm.

This is the maximum benefit electric cars have when in comparison to internal combustion motors. An Internal Combustion engine produces usable torque and electricity output only inside constrained speed variety. 

Therefore, at once connecting the engine rotation to the drive wheel is not a smart idea. A transmission must be introduced to differ the drive wheel pace.

On the opposite hand an induction motor will paintings effectively in any pace variety. Thus no velocity various transmission is wanted for an electric vehicle furthermore an IC engine does not produce direct rotational motion. The linear movement of the piston needs to be converted to rotational motion. 

This reasons major troubles for mechanical balancing. Not most effective is the inner combustion engine no longer self-began like an induction motor in addition, the electricity output of an IC engine is continually uneven.

Many accessories are needed to resolve these issues. On the alternative hand you will have direct rotational movement and uniform energy output with an induction motor many components inside the IC engine may be averted right here.

As a result of those elements, a super response price and higher electricity to weight ratio comes evidently to an induction motor ensuing in advanced automobile performance. 

But from where does the motor acquire electricity? The battery produces DC electricity so earlier than deliver get to a motor it must be transformed to AC. An inverter is used for this cause.

This strength digital tool additionally controls the Ac energy frequency as a result controlling the motor velocity.

Moreover the Inverter may even range the amplitude of the ac power which in flip will manipulate the motor electricity output.

Thus the inverter acts because the brain of the electrical car Now permit’s turn our attention to the battery p.C.

You may be surprised to locate that they are just a collection of commonplace lithium-ion cells similar to the ones used on your day by day lifestyles.

The cells are linked in a combination of series and parallel to provide the power required to run your electric powered automobile Glycol coolant is surpassed thru steel inner tubes through the space among the cells.

This is one principal innovation of Tesla via using many small cells in preference to a few huge cells. 

Effective cooling is assured This minimizes thermal hot spots and even temperature distribution is executed main to better battery percent life. The cells are organized as removable modules. 

There are sixteen such modules inside the battery % constituting around 7, 000 cells. The heated Glycol is cooled down via passing through a radiator, that is fitted at the front of the vehicle.

Moreover you may see how this sort of low height battery p.C. When geared up near the floor degree will lower the car center of gravity. 

The decrease of gravity improves the stableness of the automobile significantly. The huge battery % is likewise unfold across the floor offering structural tension towards facet collisions. Now let’s get back to Tesla’s drivetrain. 

The electricity produced with the aid of the motor is transferred to the drive wheels through a gearbox. As previously mentioned, tesla version s uses a easy Single velocity transmission because the motor is green in a extensive range of working situations. You can see that output velocity from the motor is reduced in steps. Even accomplishing the reverse tools is pretty easy in an electric vehicle. Just alternate the order of the power segment for this.

The handiest reason of electrical vehicle transmission is velocity reduction and associated torque multiplication. The 2d issue inside the Gearbox is a differential. 

The decreased speed drive is surpassed to it. You can see that is a easy open differential.

However, open differentials, have a trouble of traction manage. But why does such a complicated vehicle use an open differential in place of a restricted slip differential? The answer is that the open differential is more rugged and may deliver more torque.

A hassle that occurs in an open differential can efficaciously be triumph over with assist of two methods: selective braking and cutting the power deliver In an Internal combustion engine this power deliver reduce via reducing the fuel isn’t so responsive In an induction motor, but, the energy supply reduce is quite responsive and an powerful way for obtaining traction control In the tesla this could all be achieved using a contemporary algorithm with assist from Sensors and controllers In brief, Tesla Motors has replaced a complicated mechanical hardware device with smart, responsive software program. 

Did you recognize an electric automobile could be pushed correctly with the help of just one pedal? This is because of its effective regenerative braking machine. 

That way saving the huge kinetic strength of the automobile in the form of electricity with out losing it as heat In an electric vehicle, as soon as you launch the accelerator pedal the regenerative braking comes into motion. 

The exciting thing is that in the regenerative braking the equal induction motor acts as a generator Here the wheels pressure the rotor of the induction motor We know in an induction motor the rotor speed is much less than the RMF speed To convert the motor to a generator. You simply need to ensure that the rotor speed is more than the RMF speed.

The inverter performs a vital position here in adjusting the enter electricity frequency and preserving the RMF velocity under the rotor pace This will generate electricity inside the stator coils, that is way better than the provided strength The generated electricity can then be saved inside the battery percent after the conversion.

An opposing electromagnetic force acts at the rotor all through this procedure, so the pressure wheels and the auto will slow down. 

This manner automobile speed may be accurately controlled during the power the usage of a unmarried pedal. The brake Pedal may be implemented for a complete prevent As you might already be aware, electric powered vehicles are much safer than inner combustion vehicles.

The fee of keeping and using an electric powered automobile is lots decrease than that of an IC engine automobile.

With the drawbacks of the electrical car refrained from through the arrival of progressed era, electric motors promise to be the vehicles of the future We assume mr. . J.
