Quantitative Analysis of Sustainable Energy Based Charging Systems

In today’s world, the most rapidly growing technology is the mobile phone. People rely on mobile phones for communication, web surfing, entertainment, finance (e-wallets) and navigation among many other purposes. The most important element which keeps the mobile phone alive is its battery. These mobile phones use rechargeable batteries which are recharged through a power source, adapter and a wire after the battery has drained out. It is very inconvenient to charge a mobile phone outdoors where a power source is not accessible. Nowadays, wireless chargers and power banks are also used as a substitute to the conventional way of charging. But these methods have proven to be inefficient. There is a lot of research and experimentation going on to provide a more effective and portable method to charge the mobile phone. Though people have come up with innovative projects which involve the use of solar energy, thermoelectric energy etc., there is a great demand for new technology which drastically changes the way we charge our mobile phones. In this paper, various existing portable mobile charging techniques are discussed and highlighted their limitations. Further we have pinpointed the future scope in this field.
