The work proposes a simple multiple fast charging system that utilizes locally available materials and components to simultaneously charge 60-180 phones. The designed charging station will be flexible and can be updated to charge a large number of phones simultaneously. The charging station will be made of lithium batteries of 3 kW and locally-made solar panels and inverter with and intelligent monitoring camera. The solar-powered multiple charging system will be design to be mobile, flexible and compatible with any type of phone. The problem of overcharging which may cause thermal run-away and battery explosion will be eliminated by the inclusion of intelligent charge controller. This charging system will be cost effective for business owner, higher institutions, or other public spaces. While the system will be design with a minimum life-span of 15 years, it is expected that the payback period on the investment is 1 year if fully utilized. However, it can be upto 2 years if it is not fully operation. In either way, it is a very good investment for small-scale business.

The importance of mobile phones for communication, internet browsing, social media interaction, GPS navigation, Entertainment, Email access, Online shopping, Banking and financial transactions, etc cannot be overemphasized. Therefore, mobile devices are an integral part of our lives. However, it is important that the phone must be effectively recharged because repeatedly allowing the battery to drain fully may shorten its life and decrease its overall capacity, which in consequence will affect the performance of the users. It should be noted that the efficient charging and recharging of the phone depends on the provision of adequate power and constant energy supply. Sadly, there is incessant energy generation and inadequate and epileptic power supply in most developing countries. Consequently, there is a need for an alternative solution of developing an autonomous multiple phone charging system. Most of the multiple charging station systems developed are limited to a maximum of charging 10 phones simultaneously. Although the past few decades have witnessed the development of wireless charging systems that make remote charging possible, the incorporation of certain protective functionality is still a concern in the charging system design. Additionally, the inductive charging station system is relatively expensive which a small-scale business owner might not afford. Moreover, the wireless system still depends on the erratic electricity supply from the national grid. Therefore, this project proposes a simple multiple fast charging system that utilizes locally available materials and components to simultaneously charge 60-180 phones. The designed charging station will be flexible and can be updated to charge a large number of phones simultaneously.
