Tags: , , , , ,


Introduction :

In the previous decade, the green cars business has encountered a transformation. While traditional vehicles are still strong, the production of reasonable, mass-produced hybrid and electric cars has started an uprising. Numerous individuals are picking electric cars over non-renewable energy source vehicles since they are less expensive to drive and help lessen harm to the climate. The expense of charging an electric car is substantially less than the expense of topping off the tank, and the cost of a new hybrid or electric car has dropped significantly in the course of recent years. These cars additionally aren’t as noisy which diminishes noise pollution and makes communities calmer. While it seems like electric cars are the most consistent move, it’s as of late that innovation has made them both inexpensive and efficient.

Throughout the long term, various innovators dealt with electric cars ideas. However, every one of them confronted obstructions like battery size, battery life, and cost. Along these lines, there was next to no enthusiasm for endeavouring to mass-produce an electric vehicle until the 1970s. The Arab Oil Embargo of 1973 and the rising cost of oil brought back enthusiasm for clean alternative energy sources. Electric car research kept going during the 70s and 80s with little achievement. In any case, while completely electric vehicles were not yet industrially practical yet, the examination was put to use in making a hybrid. In 1997, the Toyota Prius turned into the primary mass-produced hybrid car, and numerous others before long followed. What was from the outset just a trend has taken off, and hybrids can be found in the city around the globe now. 

From that point forward, various automakers have explored different avenues regarding electric cars including the Tesla Motors Company. An ever-increasing number of nations have pledged funds for electric vehicle research and made least fuel-efficiency arrangements a reality. As gas rates keep on rising, an ever-increasing number of individuals are searching for options. In certain zones, gas rates are more than $4 a gallon, and those on fixed wages have been compelled to discover options in contrast to driving. For a few, this implies utilizing more open transportation or walking and biking. For other people, exchanging their gas-swallowing vehicle for a hybrid or electric vehicle is the most ideal alternative.

In 2012, deals of electric cars significantly increased which results in more than 100,000 new electric vehicles on the streets. When more and more hybrid vehicles become available,more cash incentives for the procurement of electric vehicles become successful and gas prices rise.Consumers are bound to purchase these alternative electric cars. While there are surely a few weaknesses to electric vehicles right now. For example, an absence of promptly accessible charging stations in numerous territories, these difficulties are required to be defeated soon. Actually, market leaders hope to see in excess of 40% of all vehicles run on power by 2035, bringing about a saving of practically 1.5 million barrels of oil each day. 

Make your regular car all the more Environment-friendly green car

Regardless of whether you can’t manage the cost of an electric vehicle, there are a few things you can do to change your conventional vehicle over to a more eco-friendly one. A portion of these is as straightforward as utilizing distinctive oil, while others include changes to your driving propensities. 

Here are the absolute least demanding things to make your vehicle all the more environment friendly :

1. Obey the driving speed limits and don’t quickly accelerate. This helps save money on gas. 

2. Utilize synthetic oil and high-flow air filters. 

3. Replace the spark plugs on a regular basis. 

4. Use cruise control to keep up your speed and decrease acceleration. 

5. Perform usual  car maintenance. 

6. Turn off the car in the event that you hope to keep it idle for longer than 30 seconds. 

7. Eliminate any surplus weight from your vehicle. 

8. Keep your tires appropriately inflated. 

9. Use car covers to guard your vehicles when you’re not driving them or overnight. 

You can likewise change your car over to something all the more friendly to the environment. Changing a standard engine over to one that utilizes natural gas should be possible with a CNG conversion kit. You can also change diesel engines to run on straight vegetable oil or on highly concentrated ethanol. You can even change your hybrid into an electric vehicle, despite the fact that these transformations are more costly. 

Primary distinctive factor among Hybrid Electrical Car 

A hybrid electric vehicle (HEV) has two sorts of energy storage units, electricity and fuel. Electricity implies that a battery is utilized to store the energy and that an electromotor will be utilized as a traction motor. Fuel implies that a tank is required, and that an Internal Combustion Engine (ICE) is utilized to create mechanical power, or that a fuel cell will be utilized to change fuel over to electrical energy. In the last case, traction will be performed by the electromotor only. In the principal case, the vehicle will have both an engine and a motor. 

  • Depending upon the drive train structure, we can differentiate between parallel, series or combined HEVs. 
  • Based upon the portion of the electromotor to the traction power, we can discern mild or micro-hybrid (start-stop systems), power assist hybrid, full hybrid and plug-in hybrid.
  • Depending upon the idea of the non-electric energy source, we can differentiate combustion (ICE), fuel cell, hydraulic or pneumatic power, and human power. In the first case, the ICE is a spark-ignition engine (gasoline) or compression ignition direct injection (diesel) engine. In the initial two cases, the energy transformation unit might be powered by gas, methanol, compressed natural gas, hydrogen, or other alternative fuels. 

The “work horses” of Hybrid Electric Vehicle Drive Systems are motors. The electric traction motor powers the vehicle’s wheels. In contrast to a conventional vehicle, where the engine must ramp up before full torque can be given. An electric engine gives full torque at low speeds. The engine additionally has low noise and high efficiency. Other attributes incorporate amazing “off the line” acceleration, great drive control, great adaptation to non-critical failure and adaptability comparable to voltage changes. 

Accessories, for example, power steering and air conditioning are powered by electric motors as opposed to being connected to the combustion engine. This permits productivity gains as the accessories can run at a consistent speed or can be turned off, paying little heed to how quick the combustion engine is running. Particularly in long stretch trucks, electrical power steering saves a great deal of energy. 

Types by drivetrain structure 

1.Series hybrid 

In a series hybrid system, the combustion engine drives an electric generator (generally a three-phase alternator in addition to a rectifier) rather than straightforwardly driving the wheels. The electric motor is the key way to provide power to the wheels. The generator charges a battery and drives an electric motor that pushes the car. At the point when large amounts of power are required, the motor draws electricity from both the batteries and the generator. 

A fuel cell hybrid electric has a series design: the engine generator combination is replaced by a fuel cell. 

Shortcomings of series hybrid vehicles: The ICE, the generator and the electric motor are dimensioned to deal with the full power of the vehicle. Hence, the complete weight, cost and size of the powertrain can be over the top. The power from the combustion engine needs to go through both the generator and electric motor. During significant distance expressway driving, the total efficiency is substandard compared to a conventional transmission, because of the few energy conversions. 

Example of SHEV : Renault Kangoo 

2. Parallel Hybrid

In parallel hybrid systems, both an internal combustion engine(ICE) and an electric motor are connected to a mechanical transmission.

Most designs join an enormous electrical generator and a motor into one unit, regularly situated between the combustion engine and the transmission, in place of both the conventional starter motor and the alternator. During regenerative braking and cruising (when the ICE strength is higher than the required strength for propulsion), the battery can be recharged. As there is a fixed mechanical link between the wheels and the engine (no clutch), the battery can not be charged while the car is not moving. 

Pros of Parallel hybrid vehicles

  1. Total efficiency is higher during cruising and significant distance expressway driving. 
  2. Enormous adaptability to switch among electric and ICE power 
  3. Contrasted with series hybrids, the electromotor can be planned less powerful than the ICE, as it is helping traction. Just a single electrical motor/generator is required. 

Cons of Parallel hybrid vehicles

  1. Rather complicated systems. 
  2. The ICE doesn’t operate in a limited or constant RPM range. Hence efficiency drops at a low rotation speed. 

As the ICE isn’t decoupled from the wheels, the battery can’t be charged at a standstill. 

Example of PHEV : BMW 7 arrangement Active crossover 

3. Combined Hybrid

Combined hybrid systems have highlights of both series and parallel hybrids. There is a two-way relation between the engine and the drive axle: mechanical and electrical. This split control method enables mechanical and electrical power to be interwined at some cost of a multifaceted type whereas power splitting systems are interconnected in the powertrain. The wheels may have either mechanical or electrical control or both. This is additionally the situation in parallel hybrids. In any case, the fundamental guideline behind the combined system is the decoupling of the power provided by the engine from the power requested by the driver. 

Pros of combined hybrid vehicles: 

  1. Greatest adaptability to switch among electric and ICE power. 
  2. Decoupling of the power provided by the engine from the power requested by the driver takes into account a smaller, lighter, and more efficient ICE. 

Cons of combined hybrid vehicles: 

  1. Complicated systems are more costly than parallel hybrids. 
  2. The efficiency of the transmission of the powertrain depends on the amount of power transmitted through the electrical path, as multiple conversions, each with its own efficiency, results in lower efficiency of that path (~70%) compared to the strictly mechanical path (98%). 

Example of CHEV: Toyota Prius, Auris, Lexus CT200h, Lexus RX400h.

Why you must begin the usage of Electric Vehicles (EV)?

There are several explanations why human beings are moved to Electric Vehicles (EV) in order to get them to the places they want to be. These include:

  • EVs are fun to drive due to the fact they are quick and smooth.
  • Many research exhibit that the emissions from burning fossil fuels such as fuel produce damaging greenhouse gases.
  • EV’s produce no pungent fumes or detrimental greenhouse gases.
  • EVs are modern and cool. 
  • Electric vehicles solely value about $360 a year to function in contrast to $3600 for a gas vehicle.

What is the distinction between an Electric Vehicle and a Hybrid?

There are three sorts of electric-powered vehicle: Battery Electric Vehicle (BEV), Plugin Hybrid Electric Vehicle (PHEV) and Hybrid Electric Vehicle (HEV).

  • Battery Electric Vehicle (BEV) / Electric Cars

A battery electric vehicle (BEV) runs completely the use of an electric powered motor and battery, barring the guide of a regular inside combustion engine, and need to be plugged into an exterior supply of electrical energy to recharge its battery. As all electric-powered vehicles, Electric cars can additionally recharge their batteries by means of a procedure known as regenerative braking, which makes use of the vehicle’s electric powered motor to help slow down the vehicle and improve some of the strength commonly converted into warmth by means of the brakes.

Pros :

  1. No emissions
  2. No gasoline or oil modifications
  3. Ability to comfortably cost at domestic
  4. Fast and easy acceleration
  5. A low fee of operation about $30 a month.


1. Shorter range than gasoline vehicles, though most human beings drive properly inside the vary of today’s BEV and may want to lease a hybrid for the uncommon lengthy trips.

2. Slightly extra highly-priced than their gasoline-equivalent though the gasoline savings pay off the difference in usually 2-3 years.

  • Plug-in Hybrid Electric Vehicle (PHEV)

Plug-in hybrids (PHEVs) use an electric powered motor and battery that can be plugged into the power grid to charge the battery. However, additionally has the support of an interior combustion engine that may additionally be used to recharge the vehicle’s battery and/or to change the electric powered motor when the battery is low. Because Plug-in Hybrids use electricity from the power grid, they often realize extra savings in gasoline expenses than traditional hybrids electric powered motors (HEV).


  1. Longer range than BEV
  2. Less fuel consumption than gasoline solely automobile
  3. Fewer emissions
  4. Very easy mechanics, much less to go wrong.


  1. Produces tailpipe emissions
  2. Needs gasoline and oil changes
  3. More costly to function than Battery Electric Vehicle (BEV) however much less than a traditional hybrid car (HEV).
  • Hybrid Electric Vehicle (HEV)

Hybrid Electric Vehicles (HEVs) have two complementary drive systems: a gasoline engine with a fuel tank; and an electric powered motor with a battery. Both the engine and the electric-powered motor can flip the transmission at an equal time, and the transmission then turns the wheels. The electricity grid can not alone recharge HEVs rather all their energy comes from gasoline and from regenerative braking.


  1. Longer range than BEV
  2. Less fuel consumption than gasoline solely car
  3. Fewer emissions than gasoline solely car


  1. Still produces emissions
  2. Complex mechanics – Gasoline + Electric
  3. Expensive to function (8-10 times more high priced than BEV) however much less than traditional gasoline vehicles.
  4. No capacity to easily charge at home
