Hybrid Bicycles: A Case Study Of Hybrid Electric Vehicles

Absract-The traffic congestion,energy and environmental considerations are boosting the interest for Light Electric Vehicles.Electrically Power Assisted Cycles (EPAC’s) show a great potential: They are cost effective,safe, easy to use and have a small footprint. In this project, we introduce a Hybrid Electric Bicycle.The hybrid electric bicycle is meant as a challenge to get,on sunny summer days to provide the most pedal assistance as possible.E-bikes need large and heavy batteries to allow riding long distance because the battery is charged only once at home.The pv pannels have enough power and give the bicycle an infinite range.The cost of electrical energy that would be needed to cycle a whole day is very less.in this way comparariviliy
A closer look reveals that electric mobility is reiterating some of the errors of fossil fuel mobility. In most cases, electric mobility is embodied by vehicles where a battery and an electric motor replace the internal combustion engine and tank. The resulting large battery packs increase the cost and thus reduce the attractiveness of these solutions for the final user. If we are to solve the pollution, cost and congestion problems of the 21st century mobility, a more integrated and all-around solution has to be adopted. Bicycles could play a critical role in this scenario. Bicycles are extremely cost effective, eco-friendly, healthy, and, in congested cities, are often the fastest way to reach one’s destination The solar electric bicycle is meant as a challenge to get, on sunny summer days, the most pedal assistance as possible out of the solar panel used. The solar electric bicycle is sportive. It may not cost substantially more energy to drive the solar electric bicycle, when not powered, than a normal bicycle. When there is no sunlight or the batteries are empty the bicycle should still be light running. E-bikes need large and heavy batteries to allow riding long distances, because the battery is charged only once at home. The solar bike approach is different. The PV panels have enough power and give the bicycle an infinite range. The battery is small, and saves weight.
These petroleum products are non-renewable sources and it has a danger of exhaustion in future, so it is better to move to an alternate energy sources.The price of crude oil has increased significantly over the past few years and there seems to be no turning back. Moreover global warming, pollution and scarcity of traditional resources are becoming major problems. The term ”hybrid” usually implies that more than one energy source is used to power all or part of a vehicle’s propulsion. The hybrid bicycle is a project that can promote both cleaner technology as well as a lesser dependence on oil. It will run on clean electric power with the ability to recharge the battery 3 separate ways: through the charger, by photovoltaic solar panels and by dynamo. Hybrid bicycles has been since 1895 on 31 December, Ogden Bolton Jr. was granted U.S. Patent 552,271 for a battery-powered bicycle with “6-pole brush-and-commutator direct current (DC) hub motor mounted in the rear wheel.” There were no gears and the motor could draw up to 100 amperes (A) from a10-volt battery. Two years later, in 1897, Hosea W. Libbey of Boston invented an electric bicycle that was propelled by a “double electric motor. Torque sensors and power controls were developed in the late 1990s. Production grew from 1993 to 2004 by an estimated 35percent. By contrast, according to Gardner, in
