Design and Simulation of Cellphone Charging System for a Shop in Nigeria

The increase in mobile phone usage in Nigeria has been significant over the past few years, this increase is because of the growing population of Nigeria and high demand for connectivity. Mobile phones cannot be used effectively without charging their batteries whenever they are low or else they will be useless when the battery is flat. Power interruptions in Nigeria are frequent and unplanned. Charging cellphones from solar systems at private charging facility has proven to be the best option in the absence of power supply. This paper presents an overview of different types of mobile phone chargers used in Nigeria; it also presents a design of private cellphone charging system that can be installed in shops. Dynamic modelling and simulation results of the designed system are included in this paper.
