M.N.Technical Institute Kammagondanahalli, Bangalore-15 Communication Analysis and Skill Development Programme Lab TASK - 2 By: Harsharjuna. N E&C ’A’ Topic : Electric Bikes and Need of Them

Pollution:

Pollution Petrol fumes choke our atmosphere everyday and brings new evidence that our appetite for oil is poisoning the planet. If the state of affairs is already so bad, imagine the kind of the world future generations will inherit. The worst part is we are running out of oil, we feel this every time the price of oil escalates, every time we have to pay even more for a litre of petrol. And there is no stopping – it is only going to get worse.

Solution:

Solution There is a solution for this – Electric Vehicles . They run on batteries, so there is zero expenditure on petrol and better still, no air pollution. Aside from being light on your pocket and light on your conscience, the no-petrol vehicle is easy to use, lightweight and maintenance free, providing stress free experience. The advantages are obvious and the potential is limited only by your imagination. Clean, Green and Healthy.

What is an Electric Bike?:

What is an Electric Bike? Electric bikes are a new and promising alternative form of urban transportation. They provide all the advantages of a regular bicycle: fun exercise, free parking, zero emissions, and freedom from gridlock, while eliminating one of the bicycle's more serious drawbacks, lack of power. Imagine pedalling up a hill as comfortably as riding down, that's what the e-bike experience is all about. In most situations in the city, riding an electric bike will be faster and cheaper than either car or public transit. Fundamentally, an e-bike is just a regular bicycle with an electric motor to provide additional assistance. You can pedal normally and just use the motor to help out on hills and headwinds, or use the motor all the time just to make riding easier. The experience is entirely different from riding say a gas scooter or motorbike. Here the electric assistance is perfectly smooth and silent, and it complements rather than supplants human power.

How does it work?:

How does it work? With a dynamo light the kinetic energy of the spinning tyres turns the dynamo, transferring energy and ultimately powering the light. Electric bikes work oppositely. A ‘ dynamo ’ of sorts, in this case a battery, produces energy that transfers to kinetic energy in the tyres and moves them forward.

Batteries in Electric Bikes:

Batteries in Electric Bikes Electric bikes use one of three types of batteries: 1) Lead Acid (SLA) 2) Nickel Metal Hydride (NiMH) 3) Lithium Ion (Li Ion). A typical battery in an electric bike will have approximately 250W – 500W power. The 3 types of batteries are explained as follows:

1) Lead Acid (SLA) batteries: :

1) Lead Acid (SLA) batteries: They're the heaviest of the three with the shortest overall lifetime. A Lead Acid battery will last about 300 full charge cycles before it needs to be replaced. Their only advantage is the fact that they're relatively commonplace and the least expensive to replace.

Nickel Metal Hydride (NiMH) Batteries::

Nickel Metal Hydride (NiMH) Batteries : A big jump up from SLA batteries, they're much lighter and have a better overall lifetime. A NiMH battery will last about 500 full charge cycles before it needs to be replaced.

Lithium Ion (Li Ion) batteries::

Lithium Ion (Li Ion) batteries: The newest technology in batteries. They're pretty comparable to NiMH batteries, with the exception of these two differences: Lithium Ion batteries are a little bit lighter. A Lithium Ion battery will last about 800 full charge cycles before it needs to be replaced. Lithium Ion batteries are the most expensive of the three.

Advantages:

Advantages They are non-polluting vehicles. It requires non-exhaustible fuel resource. Easy to use. Requires no registration. Does not require license to drive. Rider need not wear helmet. Smooth and silent. Zero emission.

Disadvantages:

Disadvantages There are negligible disadvantages of Electric Bikes. Few of them are: Low speed Can not travel for distances above 120km. Instant charging is not possible. Can not carry weight more than 200kgs.

Approximate expense for 4 years :

Approximate expense for 4 years Electric Bike 29,200km 10Ps for =1 Km= Rs 2,920 Bike Cost = Rs 48,000 Battery cost= Rs 10,000 Total Expense= Rs 60,920 Petrol Bike 29,200 km 584 litre = Rs 47888 Bike Cost = Rs 50,000 Total Expense= Rs 97,888

Conclusion:

Conclusion Purchase Electric bikes and save our Mother Earth. IT IS YOU! WHO CAN STOP POLLUTION AND START A REVOLUTION!!
