In MATLAB, developing a model for a solar PV-based mobile charger involves creating a simulation environment that integrates photovoltaic (PV) panels, battery storage, charging circuitry, and mobile device connectivity. The model considers factors such as solar irradiance, battery capacity, charging efficiency, and mobile device specifications. MATLAB provides tools for designing the PV array, simulating solar energy generation, modeling battery behavior, and implementing charging algorithms. Engineers can analyze system performance, optimize charging strategies, and assess the feasibility of using solar energy to charge mobile devices. By simulating various scenarios and optimizing system parameters, MATLAB facilitates the development of efficient and sustainable solar PV-based mobile chargers, enabling users to harness renewable energy for powering their portable electronics.
