Essay On Solar Vehicle

REGENERATIVE BRAKING SYSTEM AND SOLAR HYBRID CAR

ABSTRACT:- Stop-stop-stop-start if we make a habit of driving in city traffic, you will know it can be a huge waste of time. What’s less obvious is that it’s also a waste of energy. Getting a car moving needs a big input of power and every time you hit the breaks all the energy you have a built up disappears again wasted in the break pads as heat. Would’t it be good if you could store this energy somehow and reuse it next time you started accelerate? That’s the basic concept of regenerative breaks, which are widely used in electric trains and the electric cars. Keywords: Regenerative braking system, solar panel, dynamo, battery,charger.

I. INRODUCTION

When brakes are applied in conventional vehicle, kinetic energy is converted into heat because of the friction produced between the brake pads and the wheels. This heat gets carried out in the environment and the produced energy gets wasted and this leads to waste of energy. Large amount of the energy wasted during this process depends upon how hard and how often brakes are applied. Electric motors basically used in electric trains, cars and other hybrid vehicles which are connected to batteries.

Usually, photovoltaic (PV) cells contained in solar panels convert the sun's energy directly into electric energy. The term "solar vehicle" usually implies that solar energy is used to power all or part of a vehicle's propulsion. Solar power may be also used to provide power for communications or controls or other auxiliary functions. Solar vehicles are not sold as practical day-to-day transportation devices at present, but are primarily demonstration vehicles and engineering exercises, often sponsored by government agencies. However, indirectly solar-charged vehicles are widespread and solar boats are available
