Battery Management Optimization with Supervision Stage: Application for Cathodic Protection System

This study presents an innovative battery management strategy for cathodic protection systems fueled by photovoltaic sources. Addressing the corrosion of vital structures such as pipelines, the integration of photovoltaic generators offers a dynamic solution. The system encompasses a 640Ah Lithium-Ion battery, a supervisory control module, and three operational switches (“Charging”, “Direct”, “Discharging”). Through derived equations, the battery’s charging and discharging behaviors are meticulously examined based on photovoltaic and battery power interactions. Simulation results validate the effectiveness of the Maximum Power Point Tracking (MPPT) control mechanism and underscore the supervisory module’s significance in protecting battery health and fortifying cathodic protection. This research underscores the pivotal role of efficient battery management in prolonging battery life and ensuring steadfast pipeline safeguarding. By harmonizing photovoltaic energy, supervisory control, and battery management, this approach presents a robust and sustainable avenue for energy optimization within cathodic protection systems.
