Solar Watch Charger Innovation

This document proposes a portable mobile charger integrated into a watch. The device would combine the functions of telling time and charging a mobile phone into a single gadget. It describes a design where solar panels on the watch strap would generate sufficient voltage to charge a battery, which could then be used to charge a mobile phone. The circuit would include solar panels, a battery, resistors, diodes and possibly a transistor to efficiently store and deliver power from the solar panels to charge a mobile phone battery. This integrated watch and mobile charger concept aims to reduce the number of devices users need to carry to tell time and charge their phones.

Portable Energy Devices

ABSTRACT
A portable mobile charger is what every human in this world is searching for. Till now we have Solar Mobile chargers and solar watches. But these two innovations are for a single purpose. So two gadgets has to be carried to see time and the other to charge your mobile. But what if these two gadgets are combined into a single gadget? To be precise, you can see time and also charge your mobile in a single gadget. The central theme of our project is to limit the number of components and the price required to see time and charge youre mobile. A watch with a mobile charger is something amusing and sounds easy to use it. A normal watch (running in battery) can charge mobile if solar panels are around it. The strap of the watch is made from solar cells (small size) which can deliver a sufficient voltage. Using solar cells on the both side of the body of watch in either series/parallel connection may increase the output voltage/current as required. The voltage so produced can be stored in a battery from which the charge stored can be used to charge a mobile. This project can be done using a circuit with necessary components.

List of Components:
1. 2. 3. 4. 5. 6. Resistor Schottky diode Zener diode Two Solar panels Battery Transistor(if needed)

Operation at a Glance:
Components rating are not mentioned. It will be explained with the circuit at the time of presentation. Dimensions of the solar panels are well within the size of the strap of a watch. The entire circuit comes under the body of the watch except the panels which are on the strap. Two solar panels (available in market) are connected in series to get a better voltage. A resistor is connected in parallel for gradual charging to the battery setup A diode (Schottky) is connected between solar panels and Battery setup for blocking purpose (to prevent discharging from battery setup during night). Zener Diodes are used to prevent overcharging of the battery. A transistor may be connected with the zener diode for switching purposes. But mostly it is not needed. The load is the cell phone battery where the required charge is supplied from the ciruit setup to the load through pins. Circuit is made for efficient charging and ratings of the components are calculated according to the necessity. This is an untouched idea by anyone and we have thought this idea and we are going to implement it Though it is not so innovative, it is purely modification and application according to the needs of humans.
