Design and Fabrication of Wind Driven Mobile charging of Automobile battery

Last crawled date: 1 year, 11 months ago

I go very often to Indian Railways in the Slipper coach and General Buggies where no electricity is in your bed side or in compartment, and during a long tour mine as well as every one's phone usually discharges.

These smartphones have a large capacity battery but its consumption because of Social and music life is big too. I was working on a smaller prototype for the Contest, but now I think, I can make a better one. So made this all in one wind turbine power bank. Mobile phones are indispensable while you are traveling, especially in a train. However, in India, you will find either no socket for charging mobile in train or you may find just 2 damaged sockets at the end of the compartment, while every passenger carries a mobile these days. So, what to do for charging your mobile while you are inside the train and your battery runs out of power. The most powerful alternative way is to use the strong wind coming inside through the windows and doors of the train. The outside wind blowing in the earth’s frame of reference is almost all the time much slow as compared to the speed of the train which goes up to 100km/hour most of the time. Hence, in the train’s frame of reference the pseudo wind which enters the window or passes by the window has nearly the same average speed, i.e. 20-60km/hour or so. A wind with this much speed is strong enough to rotate a wind turbine with high enough rpm and torque, so that even a small wind turbine can rotate a load of small dynamo for charging small batteries. And this can be easily used to recharge your mobile.
The mentioned design uses this wind energy and converts it into usable power, which can be directly fed into the mobile phone or even we can use it for charging a laptop. To accommodate the frequent change in the wind direction, a gyroscopic joint has been given in it. It can be completely disassembled, thereby making it more light in weight and portable, fulfilling its basic function of being a travel charger.



Advantages

1. It is Portable.

2. Light in weight.

3. Not affected by weather.

4. Uses Eco friendly energy for working.






Application

1. It is used for charging mobile phone battery.

2. It can be used for charging laptops, MP3 player.

3. It can be used as a power source for any small electronics equipment or device.
