Design and Fabrication of Solar Operated E-Bicycle

Abstract

As we all know the fuel rate like the petrol is increasing price steadily day by day. Again the pollution due to A vehicle in big cities and urban areas is increasing continuously. To overcome these problems, an effort is Being made to find out next alternative sources of energy for the vehicles Again, it is also not effort to get vehicles (scooters, mopeds or motorcycles) for all the category of society. Keeping this in mind, a look for some welcome to cater these economically poor people as well on provide an answer for the environmental pollution was in progress. The solar operated e-bicycle developed is driven by DC hub motor fit in back axle housing and operated by solar energy. The solar panels mounted on the carriage. Which in turn drive the hub motor by using charge the battery? When the bicycle is idle, battery will be charge the battery by the solar. This arrangement will be substitute the petrol engine, the gear box and the fuel tank in case of a chain sprocket or two wheeler, chain and gear shifting arrangement of a traditional bicycle being used by most common man. As an area of specific work, the solar assisted bicycle is fitted with a dc hub motor on front axle of a bicycle with power rating of 350W and with a travelling speed of around 25-30kemph. It is provided with a pair of lead acid batteries of 22.5 Ah each, a photovoltaic solar battery with capacity of 20 watts, a transformer of 24v 10 Amp, accelerator and motor controller of 24v 25Amp.There as well a provision for charging of the battery with 220-240V, AC wall outlet supply, just in case of Poor solar supply due to rainy or cloudy weather.
