Introduction of Electric Vehicle (EVs) | Definition | Layout | Needs

Definition of E.V:

• An electric vehicle (EV) is defined as a vehicle that uses an electric motor for propulsion.
• EVS is propelled by one or more electric motors, which receive power from an onboard source of electricity such as batteries or fuel cells, ultracapacitors or flywheel, etc.

Layout:

• Fig. shows the basic layout of an electric car.
• It consists of a battery bank, an electric motor, and a transmission system to transmit the power generated by the motor to the wheels of the car.

Need of EVs :

• The EVs are needed due to the following reasons:

1. Depletion of oil reserves
2. Need of reducing the noise pollution.
3. Need of reducing air pollution.

• The oil reserves all over the world are depleting very fast. Hence it is necessary to run the vehicles on some other type of energy.
• The EVS is a zero exhaust emission vehicle and they are noiseless too.
• Therefore their use would reduce the air pollution as well as noise pollution associated with conventional vehicles.

• Some other advantages of EVS are as follows:

1. They can be charged at home or the workplace.
2. They are easy to service and maintain as spark plugs, gears and clutch are absent.
3. EVS is easy to drive.
4. 4.They are highly reliable.
5. They reduce our dependence on petroleum.
