Advantages and Disadvantages of Electric Vehicles

Although many people are suspicious about the widespread usage of electric cars, understanding how electric vehicles might provide more cost-effective transportation while also helping to reduce greenhouse gas emissions.

Another major benefit of electric cars is that they assist to reduce the use of nonrenewable energy supplies such as gasoline, diesel, and natural gas, which are limited and must be conserved.

What is Electric Vehicle?

An electric vehicle is either partially or entirely powered by electricity. Electric cars have fewer moving components and are simple to maintain. They are also incredibly ecologically beneficial because they do not utilize any fossil fuels such as petrol, diesel, or even gasoline.

Electric cars utilize a rechargeable battery pack to power the electric motor rather than a combustion engine. The rechargeable batteries installed within the automobile must be recharged regularly.

These batteries are not only utilized to power the automobile, but they also power the lights and wipers. The most significant advantage of this sort of vehicle is that it does not generate any polluting exhaust.

It lacks the normal liquid fuel components seen in conventional gasoline-driven cars, and maintenance, and is more cost-effective. Some automobile manufacturers have created hybrid versions that can run on both electric and gas power.

Because this notion is new, individuals have little information and awareness of it. As more people begin to use electric vehicles, they will reap the benefits, and demand for EVs is Predicated to rise in the coming months.

Types of Electric Vehicles

There are Four types of Electric Vehicles, as follows:

Types of Electric Vehicles

Battery Electric Vehicle (BEV): A battery electric vehicle (BEV), is also known as a pure electric vehicle. It is a type of electric vehicle (EV) that runs only on chemical energy stored in rechargeable battery packs, with no supplementary source of propulsion.

Hybrid Electric Vehicle (HEV): HEVs are operated by both an internal combustion engine and an electric motor that draws energy from a battery. However, unlike other electric vehicles, HEV drivers charge their batteries through regenerative braking.

Plug-in Hybrid Electric Vehicle (PHEV): PHEVs builds on the concept of the regular hybrid car. They are powered by an internal combustion engine as well as a battery-driven electric motor. This allows the battery to store enough power to run the electric motor, reducing your gas use by up to 60%.

Fuel Cell Electric Vehicle (FCEV): FCEVs have many of the same components as BEVs, such as electric motors and power controllers or inverters; however, the primary energy source is different. While BEVs use battery energy, FCEVs utilize fuel cells, which are better than batteries in many aspects.

Components of Electric Vehicles

Electric vehicles are equipped with an electric motor and a battery pack. The primary advantage of electric cars is that they create no pollutants and are environmentally beneficial.

They also do not utilize any fossil fuels, therefore the automobile is powered by a sustainable source of energy. The following are the primary components of electric vehicles:

Components of Electric Vehicle
  • Charge Port: The charging port links the electric car to a power source from outside. It powers up the battery pack. The charging port is sometimes positioned in the vehicle’s front or back.
  • DC-DC Converter: The traction battery pack provides a steady voltage. However, the specifications for various vehicle complex movement. The DC-DC converter transfers the output power from the battery to the desired level.
  • Auxiliary batteries: Auxiliary batteries provide electrical energy to electric car accessories. In the event that the primary battery fails, the auxiliary batteries will continue to charge the vehicle.
  • Traction battery pack: Electric vehicle battery (EVB) is another name for traction battery pack. It provides electricity to an electric vehicle’s motors. The battery serves as a power storage system. It stores energy in the form of direct current (DC current).
  • Transmission: It transfers mechanical power from the electric motor to the wheels through a gearbox. Electric vehicles have the benefit of not requiring multi-speed gearboxes. To minimize power loss, transmission efficiency should be good.
  • Electric motor: The essential component of an electric vehicle is the electric traction motor. The wheels are rotated by this energy. The major component that distinguishes an electric automobile from a normal car is its electric motor.
  • Thermal system (cooling): The thermal management system is in charge of keeping the key components of an electric vehicle, such as the electric motor and controller, at a constant working temperature. It also works while charging to provide optimal performance. It employs a mix of thermoelectric, forced air, and liquid cooling.
  • Power inverter: It converts DC power from the batteries to alternating current electricity. It also transforms the alternating current generated by regenerative braking into a direct current. This is also used to charge the batteries.
  • Controller: The operation of an electric vehicle is determined by the power electronics controller. It regulates the flow of electrical energy from batteries to electric motors. The driver’s pedal affects the car’s speed and the frequency of voltage fluctuation input to the motor.

FAQs

Question 1

Why do electric vehicles have fewer operating expenses than gasoline-powered automobiles?

Answer: Electric vehicles utilize rechargeable batteries that can be charged quickly and cheaply, but gasoline and diesel are more expensive and prone to regular price increases. Furthermore, because electric vehicles do not experience significant wear and tear, their maintenance costs are lower.

Question 2

What are people’s worries about driving long distances with electric vehicles?

Answer: Compared to standard automobiles with a one-time charge, electric vehicles have a shorter driving range. Furthermore, there are few charging stations accessible, and charging time is also quite long, so they are concerned about a breakdown if the car requires charging in the middle of the journey.

Question 3

How safe are electric vehicles? Do they set fire to themselves?

Answer: Due to their highly combustible fuel or any electrical problems, EVs are much like ICE cars in that they are susceptible to problems. EVs have fewer moving parts than ICE vehicles, but they still require lithium-ion batteries, which generate a lot of heat while in operation.

The heat management system of EV batteries is crucial. If something goes wrong during the thermal runaway process, the EV is prone to catching fire, which can result in a fatal accident.

Question 4

Is an electric car greater than a regular car?

Answer: Yes, an electric car is preferable to an ICE vehicle since the former releases fewer vehicular pollutants than the latter. An ICE car driven by gasoline or diesel, or even a CNG-powered vehicle, emits specific pollutants. Higher fuel and energy usage hurts the environment. An EV, on the other hand, is more efficient since it uses more than half of its energy usage for propulsion and only a little portion for friction force.

Question 5

What exactly is range anxiety? Is it anything I should be concerned about?

Range anxiety is the driver’s dread linked with the energy storage (batteries in the case of EVs) to cover the road travel, and reach the intended destination, and the vehicle may become stuck in the middle of the journey. It is a significant psychological hurdle to the widespread adoption of electric automobiles.

Range anxiety is genuine and not unjustified. Range may be affected by variables other than speed, weight, and terrain. Drivers want peace of mind, hence higher ranges are preferable to put the driver at comfortable when driving.

Purchasing an EV in the middle of widespread acceptance of future mobility is not a major concern, but in developing nations like India, where EV adoption is still in its early stages, range anxiety is evident due to the lack of adequate charging infrastructure.

Question 6

Why do governments provide tax breaks to people who purchase electric automobiles to replace gasoline-powered vehicles?

Answer: Traditional automobiles use fossil fuels, which not only contribute to environmental degradation through harmful emissions, but also rapidly deplete nonrenewable resources such as gasoline, diesel, and natural gas. Electric vehicles are being promoted to minimize the usage of fossil fuels and regulate pollution.
