Multiple Smart Phones Inductive Charging Station System

Abstract

In today's technology market, more and more devices are moving towards wireless charging. For example, one of the flagship companies, Apple, recently announced that they would begin to offer wireless charging in their devices. Besides Apple, many other companies such as Samsung, LG, HTC, and Sony already offer this feature to their customers. Many consumers have issues with the prices that come with replacing disfigured cables that result from daily use. In response to this, we would like to promote wireless charging through building an inductive charging station capable of detecting and charging multiple devices wirelessly at the same time. This would eliminate the need for charging cables, and the wear and tear that comes with them. This would also be more cost effective than buying multiple copies of the wireless chargers that are already on the market. The proposed design would be able to charge up to six devices simultaneously via a coil array and detection circuit. The design takes into consideration the dimensions of the current smart devices and moves to accommodate such devices. This device would also be cost effective so that acquiring would not be an issue, be it businesses, universities, or public spaces that take an interest. The designed wireless charging station cost approximately $173. It is designed to charge different smart phones with different dimensions. Practically, our station can fully charge smart phones approximately in same time as if using wired charging cables. The designed charging station is flexible and can be updated to charge bigger smart devices.
