Mobile phones becoming a basic part of life, the recharging of mobile phone batteries have always been a problem. The mobile phones vary in their talk time and battery standby according to their manufacturer and batteries. The main objective of this current proposal is to make the recharging of the mobile phones independent of their manufacturer and battery make. In this paper a new proposal has been made so as to make the recharging of the mobile phones is done using induction principle.
This is based on Inductive charging uses and electromagnetic field to transfer energy between two objects. This is usually done with a charging station. Energy is sent through inductive coupling to an electrical device, which then can use that energy to charge batteries. Because there is a small gap between the two coils employed in each of the sender and receiver of the energy within the respective devices, inductive charging is considered a short-distance “wireless” energy transfer despite the fact that there are typically more wires used with inductive charging than direct-contact charging, because it frees the user from having to deal with wires between the two devices. Induction chargers typically use an induction coil to create an alternating electromagnetic field from within a charging base station, and a second induction coil in the portable device takes power from the electromagnetic field and converts it back into electrical current to charge the battery.
Use of embedded technology makes this system efficient and reliable. Micro controller (AT89S52) allows dynamic and faster control. Liquid crystal display (LCD) makes the system user-friendly. AT89S52 micro controller is the heart of the circuit as it controls all the functions. Also See Wireless Electricity | Robotics Projects Ideas
