Introduction:  The electric two-wheeler set-up appears a lot more promising, in the form of research, financial acquisitions & investments, that makes the electric vehicle segment thrilling. Well, there is also the forward push by the government and the references of its think-tank, NITI Aayog.

Why EV’s? The innovation of internal combustion engine is one of the best creations of humankind. The traditional vehicles with ICE provide a good performance but are the major cause for poor efficiency and environment pollution across the country.

Decreasing fuel consumption and carbon emissions are the most important goal among the present-day plan of government across the globe. Thinking about the future of a country, an efficient and eco-friendly electric two-wheeler must be designed and manufactured.

Impact of COVID-19 on Electric Two-wheeler market: Since the onset of pandemic, leading authorities-imposed lockdown restrictions and released a set of precautionary guidelines. Manufacturing units were temporarily shut down and disruption in supply chain was observed. Workers moved down to their native area which created shortage of workforce. The automotive industry including electric two wheeler market faced a setback and post COVID-19, electric two wheeler market is expected to pick up the pace eventually.

What is the need of Electric and Hybrid Two Wheelers?

All existing two wheelers that are in the market cause pollution and their fuel cost is also increasing day by day.  To compensate the changing fuel cost and curb down the high pollution levels, a good remedy is needed.

Zero tailpipe emission technologies have long been held up as the last solution to transportation-related pollution problems. Electric two wheelers have been offered for several decades. Electric two wheelers, with their zero tailpipe emissions, can significantly improve urban air quality.

Working Principle

The working starts with a battery connection.  The battery consists of two terminals one is positive and another one is the negative terminal.  The positive terminal is linked to the stator body of the motor on the other hand, the negative terminal is linked to the edge of the vehicle.

The battery and the motor are connected into series.  The wire connections were made for the flow of electrons starting with one section then onto the next part. At the point when the engine empowers through the current, the stator field coil gets magnetized and induces the rotor shaft to rotate in the counter clockwise direction. Towards the finish of the engine shaft significant conditions were made for the seating of clutch assembly. Clutch is a power transmission gadget, which offers drive to the back wheel. The Clutch get together is placed with the rotor shaft through needle orientation. On the other end of the rotor shaft an alternator is settled for the reviving framework, as it is an electrical gadget which changes over the rotational power into the electromotive power. This alternator is connected to revive the battery while the vehicle is in movement. This course of action is done through V-belt pulley.

The current flows from the battery with a guide of control framework to the stator body. This current makes the field coil temporarily magnetized with the goal that the rotor shaft tends to pivot in its virtual speed. As there is a V-belt drive between the pedal shaft and the grasp gathering, the movement of the vehicle is sufficiently attained.

The speed in the pedal shaft is constantly lessened with the utilization of sprockets. Here the speed decrease is in the proportion of 1:4. This game plan lessens the speed of the engine repeatedly. To the correct side of the vehicle there lies a chain drive for the pedal shaft. A free wheel is mounted on the back wheel to limit the turn of the pedal under running condition.

What are the principal parts of electric two wheelers framework?

Basically, a two-wheeler gets its electricity from two sources – a battery and an alternator. The function of the battery is to store charge, it maintains a stated voltage level and keeps the electrical system working when the engine is switched off.

On the other hand, the alternator, produces electricity when the engine is switched on. It provides electricity power supply to numerous electrical devices and charges the battery on the go. Let’s go in little detail of the two:

BATTERY

A 12-volt two wheeler battery is a six-cell unit and is made of a plastic having a set of positive and negative plates occupied in an electrolyte. When fully charged each cell has a voltage of around 2.1 volts, which leads to a combined voltage of around 12.6 volts. The main function of the battery is to deliver Direct Current to the vehicles electronics when the engine is turned off. Moreover, the battery also provides the current to crank up the engine.

Obviously, lithium ion batteries of some kind would be the great enabler. Lithium is a now entering the market, they are still very costly and something of a question mark. Traditional lithium cells, as utilized in PCs, have a warm runaway potential - meaning they tend to burst into flames, now and again like a Roman light. New materials and sciences considering lithium are endeavouring to address the wellbeing issue. Moreover, the prices of the lithium ion batteries have come down and the battery manufacturers are claiming no fire problems.

Battery Upgradation

ALTERNATOR

The function of the alternator is to generate electricity when the engine gets started. The alternator uses the engine’s crankshaft to turn the magnets and produce electricity. It produces alternating current (AC) which needs to be converted to direct current which is attained over a regulator which not only converts AC to DC but also regulates the amount of current that is sent to all the electronics present.

·         WIRING HARNESS

The current produced on a two wheeler is channelized through a wiring harness. It plays an essential role in connecting various electrical and electronic components on a two-wheeler. The wiring harness is a set of wires, terminals and connectors, designed for a two wheeler model to supply electric power.

·         CONTROLLERS

There are mainly two types of controllers, one is brushed, and another is brushless. According to the motor in use the function of the controller also varies. Because of high efficiency, less cost and durability, the brushless motors are popular nowadays, whereas brushed motors because of less complex controller mechanism, is still in use fairly.

Let’s have a look that how these two wheelers are produced/manufactured?

Manufacturing Unit Size: The size of the unit totally depends upon the volume of business we need to do, the quantum of assets we have available to us, and the turnover target we intend to accomplish.

For an instance:

· Hero Electric is considering over setting up multiple assembly plants to meet its target of increasing sales by ten times over the next five years, including exports. The company currently has a production capacity of 75,000 units per annum at its Ludhiana plant.
