Paavai Institutions


Rising fuel price, pollutant emission and an increasing concern for global warming initiated a transition towards electric vehicles. In our ecosystem mostly Gasoline engine cars are used by the public which have high cost of refuelling that cause emission of greenhouse gases. In this way to reduce the automotive emission which causes the Greenhouse gases, an alternative technology is needed. The most convenient way is to use renewable energy sources. In this scenario we provide an alternative fuel for vehicles by using renewable energy resources. Among the various resources available, we design a solar power controlled motor device for automotive application. Main challenge for Hybrid Electric Car is energy management system that controls power split during driving mission. Nowadays alternative fuel and advanced power system has become high priority in vehicle manufacturing.

This project of the Electric Car is the way to alter the energy source. Sunlight is the main source of energy to obtain light energy which is converted into electricity. Amount of energy obtained from the source may vary from time-to-time. The vehicle chosen for the experiment is Marathi Omni. The solar panels are placed on the top of the car. Energy obtained from the solar panel is given to the charge controller. Charge controller can prevent overcharging and also the over discharging of the battery. Output of the charge controller is given to the Valve Regulated Sealed Lead-Acid Battery. Then the Valve Regulated Sealed Lead-Acid Battery is given to the Motor through Driver circuit which controls speed of the Motor.

Hybrid Electric Vehicles uses the Valve Regulated Sealed Lead-Acid (VRSLA) battery of 48V, 165Ah in 32 set of batteries which exists as a source that provides power to the motor. In its old design the Electric vehicles do not have alternator. The vehicles are charged through plug. In our design, electric vehicle is charged by alternator, solar and wind source of energy. But plug is not necessary because the alternator connected to

the wheel of the vehicle regenerates the energy and boosts up the power which moves the vehicle.

Energy efficiency for better mileage is obtained. This work is more beneficial in the hilly region and area like college campus, school and hospitals and it generates zero pollution, zero noise effect and fuel consumption is also less. Battery charging time through charge controller is four to five hours and the Electric Car travels for the distance of about 150Km with the speed of 30 to 40 Km/hr. This project is design by final year students the department of Electrical and Electronics Engineering under the guidance of
