The whole world is moving with automobiles. Huge amount of fossil fuels are burned for automobiles. Nothing on earth is free of cost, but what if we could find a way to implement free rides? Indeed it would be wonderful if our cars could continue to run without us having to spend billions o3n fossil fuels every year and to deal with natural hazards that their combustion leave behind. Considering the availability and pollution of fossil fuels we need a substitute. The best substitute is electric vehicles which will not create any pollution to environment. The main impediment is the storage capacity of electric power, the ride is restricted up to battery capacity. This storage issue can be beaten by adding solar power to automobiles. By adding PV modules the vehicles can be charged while driving by this the driving distance can be increased. If we could drive a solar-powered car, that auto dream would come true. Solar cars would harness energy from the sun via solar panels.

A solar panel is a packaged, connected assembly of solar cells, also called photovoltaic cells which are solid state devices that can convert solar energy directly into electrical energy through quantum mechanical transitions. They are noiseless and pollution-free with no rotating parts and need minimum maintenance. The electricity thus generated would then fuel the battery that would run the car's motors. Unlike a single motor operation our vehicle is driven with two motors which are placed at the wheel hubs. By this mechanical parts like gearbox clutch drive axles can be eliminated, so the regular mechanical maintenances are not required.

With the increasingly severe environmental problems around the world, exploitation of clean and renewable energy has been a crucial topic. As indispensable transportation in modern society, vehicles are ubiquitous but also one of the main sources of pollutants. Because of their status, it is almost impossible to decrease the volume of vehicles. One solution to lowering emissions is the electric vehicle. Overall, the electric vehicle is more energy efficient, environmentally friendly, and cleaner than the vehicle that relies on fossil fuels.

An electrically powered vehicle has essentially three major electrical components. These include energy source (usually are chargeable battery bank), an inverter or, motor controller and an electric motor. In the case of a solar car, the energy source is typically a bank of batteries, which may be recharged by photovoltaic solar panels. The motor controller is typically a power electronics device which when supplied with the driver’s input commands, controls the torque and speed of the electric motor.

The solution is SPEV is supported with a charging cable that plugs in to the vehicle and into a 230v wall socket. The electric vehicle have a built in features like security system, Seatbelt Detection system, Collision detection.

WORKING

The BLDC motor is driven by an electronic drive which switches the supply voltage between the stator windings as the rotor turns. The rotor position is monitored by the Hall Effect sensor which supplies information to the electronic controller and based on this position, the stator windings to be energized is determined. These electronic drive consist of IGBTs (2 on each phase) which operate motor drive. For obtaining the rotor position a Hall Sensor is embedded on the stator. As motor rotates, the hall sensor senses the position and develops a high or low signal, depending on the poles of magnet. Control voltage is implemented by microelectronic device has several high-tech choices. This may be implemented using a microcontroller.

CONCLUSION

In order to cope with the increasing demands for fuel and the disastrous environment pollution due to driving carbon-based vehicles, it is quite necessary to switch to a new source of energy, i.e. the solar power which would be a cheap, efficient, limitless and of course an eco-friendly alternative. Solar-powered electric vehicles are safe with no volatile fuel or hot exhaust systems. They are zero emission vehicles, odorless, smokeless and noiseless. They require minimal maintenance, are more reliable with little or no moving parts and can be efficiently charged nearly anywhere. Needless to say it is very much cost efficient The Solar Powered EV would benefited by the end users like Industries, university campus, amusement parks.. The technology used in SPEV contribute its supports to Green transportation
