Abstract

Wireless charging system is a popular technology that had been developed in recent years. The demands for charging devices without cords or cable had brought this technology in trends. Nowadays, peoples usually own multiples device that leads to the collection of bulky chargers. This project is to design and develop an intelligent wireless embedded system. The work has been divided into two parts; wireless transfer between the mobile energy storage and smart phones, and wireless transfer between the mobile energy storage and AC power supply from the wall. The interface circuitries have been modeled and designed for proper wireless power transfer. A prototype has been developed to verify the functionality of the proposed system. Performance of the developed system in terms of transmitter coils placement, charging time and distance between transmissions have been analyzed and discussed. A customized pocket has been used to align the transmitter coils with the smart phone. Smart phone has been successfully charged while just left it in the designated pocket. Although the mobile energy storage in the developed system requires almost double the charging time compared to conventional wired charging, it fill up the energy in the mobile storage automatically. The proposed system demonstrates the effectiveness of the wireless charging, making a word without wires possible.
