Electric Cars Better For The Future?

Technology

What is an Electric Car ?

An electric car refers to highway-capable automobiles, propelled by electric motors, using the energy stored in rechargeable batteries.

These function by storing the electricity in rechargeable batteries that power an electric motor, which turns the wheels.

They're plugged into a charging point and take electricity from the grid.

There are three main types of Electric vehicles (EVs) classified by the degree of electricity used as their energy source. :

BEV(battery electric vehicles) more frequently called EVs, are fully-electric vehicles with rechargeable batteries and no gasoline engine. Their battery power is used to run the electric motors. They do not emit any harmful emissions and hazards caused by traditional gasoline-powered vehicles and are charged by electricity from an external source. Only BEVs are capable of charging on a level 3, DC fast charge.

Examples that can charge on DC Level 3 Fast Chargers are :

1. BMW i3

2. Tesla Model 3

3. Chevy bolt

4. Nissan leaf

5. Tesla model S

6. Kia soul

PHEV(plug-in hybrid electric vehicles) can recharge the battery through both regenerative braking and “plugging in” to an external source of electrical power. PHEV models can go anywhere from 10-40 miles before their gas engines provide assistance.

Examples of PHEV are :

1. Chevy volt

2. Mercedes S550e

3. BMW i8

4. Kia Optima

5. Porsche Cayenne S E-Hybrid

HEV(hybrid electric vehicles)are powered by both gasoline and electricity. The electric energy is generated by the car’s own braking system to recharge the battery. This is called ‘regenerative braking’,they start off using the electric motor, then the gasoline engine cuts in as speed rises.

HEV Examples :

1. Toyota Prius Hybrid

2. Honda Civic Hybrid

3. Toyota Camry Hybrid


The Roadster was the first highway legal all-electric car to use lithium-ion battery cells, and the first production of all-electric car to travel more than 320 km (200 miles) per charge. Tesla Motors began development in 2004 of Tesla's Roadster, which was first delivered to customers in 2008.

Cost Of Ownership

The total cost of ownership of electric cars as of 2020 is less than the ICE cars due to less cost of maintainance and fueling.

Operating Cost

According to a study in 2018. . The average fueling cost of an electric vehicle in the United States is $485 per year as compared to an ICE car' $1,117 per year.

Manufacturing Cost

The main cost driver for an electric car is it's battery.

The cost of battery has been decreasing from €600 per kWh in 2010 to €100 in 2019.

The cost of installing charging infrastructure has been estimated to be repaid by health cost savings in less than 3 years. It can be installed in homes or on roads.


Effect of Electric Cars on the environment :

Electric cars have alot of benefits over the ICE cars. Reduction of local air pollution, as they do not directly emit pollutants which are emitted by using ICE cars such as volatile organic compounds, ozone, hydrocarbons, carbon monoxide, lead, and oxides of nitrogen.

They are quieter than gas vehicles. The only noises EVs usually generate is caused by wind resistance or tire noises, and that is only at moderate to higher speeds.

Electricity can be a renewable resource, gasoline cannot.


Downside of electric cars :

Electric cars have a shorter range than gas-powered cars. Recharging the battery takes time. They are usually more expensive than gas-powered cars.

Future of electric cars :

Currently EVs make up to 3% of the global car sales. In upcoming time electric vehicles (EVs) will hit 10% of global passenger vehicle sales in 2025, with that number rising to 28% in 2030 and 58% till 2040.
