Electric vehicles

replacement of conventional vehicle to reduce the leading cause of pollution, globally.

Dr. Asma Ali ( Ecologist)

Tata sons chairman emeritus Ratan Tata made investment in ola electric mobility, the electric vehicle unit of cab hailing major Ola. According to Ratan Tata “The electric vehicle ecosystem is evolving dramatically everyday and I believe Ola electric will play a key role in its growth and development”. Ola Cabs is an Indian origin online transportation network company, developed by ANI,Technologies Private Limited. Ola cabs was founded on 3 December 2010; till 2018 the company has expanded its network across 169 cities of India with more than 10 lakh vehicles and in January 2018 ola spreaded  its overseas market in Australia and New Zealand.

Introduction

Electric vehicles (EVs) powered through a collector system by electricity, first came into existence in the mid 19th century but increased focus on renewable energy and technological approaches it proliferated rapidly. When we compare ICE vehicle (internal combustion engine) with EVs (electric vehicles), one of the common assertion comes out all the time in our mind whether EVs are more efficient than car powered by internal combustion engine? 

         

According to the US department of  ENERGY EFFICIENCY AND RENEWABLE ENERGY; EVs convert about 59% to 62% of electric energy from the grid to power at the wheels. Conventional gasoline vehicle only convert about 17 % to 21% of the energy stored in gasoline to power at the wheel.

The charging time of an electric car can be as little as 40 minutes or more than 12 hours. This depends on the size of battery and the speed of charging.

On the other hand, if a large proportion of electric vehicle would be used in developed countries, where per capita car ownership is quite higher ( as shown in chart); it would definitely increase the demand of electricity generation. 

However overall energy consumption and emission would diminish because of the higher efficiency of EVs over the entire cycle. Steve Holliday ( CEO, National Grid PLC) said “penetration up and above that becomes a real issue. Local distribution network in cities like London may struggle to balance their grids if drivers choose to  all plug in their cars at the same time”.

List of countries by vehicles per capita

• San marina           1,263
• Monaco                    899
• New Zealand           839
• United States           837
• Iceland                      795
• Liechtenstein           773
• Australia                   747
• Luxembourg            737
• Malta                        738
• Brunei                       721
• Italy                           695
• Canada                     670
• INDIA                          22

In case of India things are quite different when we see the list of countries by vehicles per capita we can sketch out the significance of electric vehicle globally. Increased use of vehicle poses several social, economic and environmental challenges.

As we all know emission of gases from vehicle causing Lethal impact on Environment. To reduce expansion of pollution we can replace conventional cars by EVs.

  Power generated in 2016

   CHINA             6,015(TWh)

   US                   4,327(TWh)

   INDIA              1,423(TWh)

Data suggested that India is now the world's third largest electricity producer. After China ( 6,015 TWh) and US (4,327 TWh); India (1,423 TWh) generated 4.72 more electricity in 2018, when compare it with 2017 ( however power generation is not adequate as per demand).

Amitabh Kant (CEO Niti Aayog) articulated “ from the perspective of energy security and competitive advantage, new mobility solutions will reduce oil import cost, lower trade deficits and limit vulnerability to oil supply descriptions and process shocks. Finally shared, connected and clean mobility solutions will deliver a host of environmental benefits”.

    Best EVs COMPANIES

• TESLA,Inc.  is an American automobile and Energy Company based in Palo Alto, California, founded in July 1, 2003. Tesla is specialise in electric car and solar panel manufacturing. Tesla delivered over to 245,000 vehicles in 2018. The Tesla model 3 was the best selling electric car in the world in 2018 according to data firm JATO dynamics.
• BAIC (Beijing automotive industry holding Co.Ltd.) is a Chinese state owned Enterprises and holding company of several automobile and machine manufacturers, located in Beijing China.
• BYD (Build Your Dreams) is China based company established in January 2003, produces automobiles, buses, electric bicycles, rechargeable batteries and trucks. In 2012 the company became the 9th largest car manufacturer in China producing over 6,00,000 vehicles.

In this scenario as we know that we have Limited stock of fossil fuel, which is not enough to meet the rising demand. After few years, this priceless natural Treasure will be over and we will be left empty. Although we cannot completely control on the uses of natural petroleum but we can replace it with its substitute.
