Abstract

The increasing global demand for energy and the need for sustainable power generation have accelerated the integration of renewable sources such as solar and wind into hybrid power systems. However, the intermittent nature of these sources leads to instability in the charging and discharging cycles of energy storage units, primarily batteries. This study focuses on optimizing the charging and discharging processes of lithium-based batteries in a hybrid renewable energy system (solar–wind) using an intelligent Battery Management System (BMS) integrated with a Maximum Power Point Tracking (MPPT) solar charge controller and Low Voltage Disconnect (LVD) protection. The research involves prototype implementation consisting of four 3.3 V, 20 Ah LiFePO_₄ cells configured in series (12.9 V total) and a 300 Wp photovoltaic module. Experimental results show that the developed BMS effectively balances cell voltages and prevents overcharging or overdischarging. During charging tests, voltage deviation among cells was maintained within 0.46%–1.63%, while in discharging tests, deviation remained below 2.61%, indicating stable and balanced performance. The integration of MPPT and LVD controllers improved overall energy conversion efficiency and prevented deep discharge damage, enhancing battery lifespan and system reliability. The study concludes that optimal battery management significantly improves hybrid system performance, ensuring efficient renewable energy utilization for off-grid or standalone power applications.
