Electric Cars and Petrol Cars
The video about the comparison between electric cars and gas cars is based on finding out the differences as well as the pros and cons of using either of the two. The video is from the “E for Electric” channel in the YouTube site, which is not a popular channel either, but through the video, we get a better understanding of the differences between the two types of cars. The manager of the channel, Evannex, uses the channel to talk about electric vehicles, and in this case, his content is most valid(“YouTube”). Generally, there are significant differences as well as merits and demerits of using gas cars over electric cars. The reporter also talks about the other kind of cars called Hybrid vehicles but are not inclusive in the video.
Almost two centuries ago, in 1828, a Hungarian engineer named Anya Jedec invented the prototype of the electric motor and used it to power the small model car. He wasn’t the only one with interest in that sort of technology. In 1834, blacksmith Thomas Davenport created a similar device that could be driven at short distances using an electric track.And over in the Netherlands university professors, so the brand is straddling build a tiny electric car powered with non-rechargeable batteries(Abraham, 36). Now, even though the idea of a battery-powered vehicle was to revolutionize people’s lives for the better primary cell batteries. They needed too many batteries to run the motor over long distances at such low speeds. It was not until 1859 when the French physicist guest on plot invented the lead-acid battery that changed the electric engine game for a good many countries began producing electric three-wheeled cars until the US made a huge breakthrough. In 1891 they created the first electric vehicle, and it was a six-passenger wagon that could go up to 14 miles per hour. After that, people were thrilled, and the electric car was marketable in the late 1890s Electric Power taxis filled the streets of London. At that time, electric vehicles had many advantages over steam-powered and gas-guzzling engines. They did not vibrate, and they didn’t give off that awful burning gasoline smell that we’re all familiar with.
And most importantly, they did not require much effort to start. By the early 1900s, almost one-third of cars in the US were electrically powered. But that wasn’t going to last for long, and by the late 1920s, infrastructure in the US had improved significantly, and vehicles needed to go further and more efficiently. So fossil fuel cars took the lead because they got the job done. The top speed that electric vehicles could achieve was 15 to 20 miles per hour. Another problem was that electric-powered engines back then could only travel 30 to 40 miles on one go, which means they need charging every couple of hours.
In the 21st century, there have been advancements in technology and a more significant concern for the environment, and a fear of running out of resources to fuel our vehicles. This is the reason why automotive companies have decided to give electric cars another chance(Morgan, 12). The main difference between electronic and fossil-fueled cars is that the E-cars can use a variety of renewable resources to generate their electricity. However, with recent improvements in battery technology and power electronics, electric cars have made a strong comeback.
Opinion
Electric cars have internal combustion engine cars, which is better. Electric cars were in the season back in 1900. But a sudden rise in petrol engine cars accompanied by battery technology, inefficiencies killed electric cars by 1920. Compared to these different technologies scientifically and come to understand which is superior and I see the engine is the prime mover in petrol-driven vehicles. Fuel supply to the engine produces combustion and enough pressure and temperature energy to move the pistons the linear motion of the piston is transferred to rotary motion using a slider-crank mechanism.
Response
Transmission is used to transfer this rotation to the drive wheels In an electric car the power source is from a battery pack an inverter converts the DC battery power into three-phase AC (Suroso et al. 1212). The three-phase AC can turn an induction motor, which will become the drive wheel. The reciprocating components cause substantial mechanical balancing issues. Also, the engine is not self-started, many accessories needed to sort out these issues, which makes it icy engine quite heavy. Such problems are not there in an electric motor. The induction motors work with the help of a rotating magnetic field generated by the state or easily control motor speed by adjusting the frequency of the AC power input. They produce true power and speed output enter self-started for these reasons induction motor is much lighter than an IC engine, and at the same time, provides much higher power and torque output. It is interesting to note that both the IC engine and induction motor require cooling. Both the prime movers must reject the waste heat generated to keep the temperature within a specific limit.
Importance
The main advantage of an IC engine car is the ease with which it can be refueled. A petrol car can be refueled in five minutes or less. However, recharging electric cars can take at least one hour as of this present moment. Another significant advantage of petrol cars over electric cars pertains to their high energy density. The energy density of the current lithium-ion battery is nowhere near to that of the gasoline(Hoffman 45). Both these cars produced comparable travel rages. You could compare the size and weight of their energy storage devices. The poor and density of the battery contribute a colossal weight penalty to the electric car. The massive weight of the vehicle reduces the coefficient of friction between the tire and road, considerably making quartering difficult.
Future work directions
The battery pack also has huge heat generation issues. If you tear down the battery pack of an electric car, you will see that the battery pack is a collection of standard lithium-ion cells that you might use in your daily life. Continuous liquid cooling is required to keep battery temperatures at normal levels. The removed heat is rejected to the atmosphere via a radiator. Petrol cars energy storage Park does not require any such cooling mechanism. The battery pack of electric cars does have advantages as well. Because the heavy battery pack is sitting very low to the ground. It lowers the center of gravity and increases car stability. The overall safety is improved. The large battery pack is also spread across the floor, offering structural rigidity against side collisions. Another primary difference visible from these visuals is that in an IC engine car, a complex exhaust gas treatment is needed to keep pollutants and noise at statutory levels. Compare the power dynamics of these two technologies, and electric cars are the clear winner here since engines cannot be operated beyond a certain speed range. This necessitates the use of a complex and costly transmission mechanism for speed control. The motor can work efficiently in a wide speed range. So in an electric car speed can be controlled directly from the motor. As a result of varying speed, the transmission is not required for an electric car. Induction motor speed is accurately controlled by the inverter simply by adjusting the output power frequency. The use of electric cars betters the use of petrol cars, even in the preservation of the environment.
