If you spot an electric car on the street, it is nearly impossible to tell that the car is powered by an electric motor because EVs (electric vehicles) look exactly like a gasoline powered car. If you are an automobile enthusiast, you would probably know the EVs that are available in your country and this may help you to figure out a car is powered by an electric engine. The only other way to find an electric motor powered car is the excellent level of silence that an electric engine has!
The entire technological differences between an EV and gasoline powered car are kept under the hood; so you need to open the hood to know how they work. For those who have gasoline cars, their engine bay features so many boxes and pipes which look like a complicated plumbing work but with electric cars, this is definitely different and will look like some electrical work. The car will be using an electric motor to power its wheels and this engine will be different from a traditional gasoline powered engine.
The electric engine directly uses electricity and starts rotating, which means the power output is instantaneous and the maximum power can be enjoyed from the very beginning. However, these engines have a downside when it comes to climbing hills. This system will not provide adequate power for hilly surfaces and electric car makers all over the world are working hard on resolving this issue. Traditionally, electric engines were powered by normal car batteries that didn’t last longer. However, this issue has been resolved with modern car batteries that allow you to drive your eco-friendly vehicles for quite a long time.
The Working Principle
In an EV, there is an ac charger which will charge the battery unit. Once you start the engine, the power will be directly delivered from batteries to the car. Instead of a gasoline meter, an EV will have a volt meter that will show you the charge. If the volt meter shows a low charge warning, it means that you should recharge your car immediately. The EV motor do not have clutch as the motor has limited control over its power output. Instead of an accelerator, it is a potentiometer that allows you to increase or decrease the speed.
To make the air conditioner work, there will be an additional battery source and for heater, a water heater will be fixed in the engine bay. The power windows and other accessories also use the electric charge and replacements are made. The potentiometer used in an electric car is similar to a fan regulator and works based on the resistance principle. However, increasing or decreasing the speed can’t help you to achieve a higher or lower mileage as the power output as well as energy consumption will be the same.
This is how EVs work, which is a very straightforward principle. There is no doubt that electric cars can help you to save a lot of money that you used to spent on fuel.
