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:
- Depletion of oil reserves
- Need of reducing the noise pollution.
- 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:
- They can be charged at home or the workplace.
- They are easy to service and maintain as spark plugs, gears and clutch are absent.
- EVS is easy to drive.
- 4.They are highly reliable.
- They reduce our dependence on petroleum.
