Abstract

“Optimizing Hybrid Solar EV Charging Station with On-board EV Battery Management System” Electric vehicle (EV) adoption is growing, and in order to significantly reduce grid stress and dependency on fossil fuels, efficient, affordable, and ecological charging options are required. An optimized hybrid solar EV charging station with an on-board battery management system (BMS) is designed and simulated in this study using MATLAB Simulink. Contrary to traditional charging models, this system uses a real-time power balancing algorithm that, in response to current supply and demand, dynamically modifies the energy flow between grid power, solar photovoltaic (PV) panels, and battery storage. A bidirectional charging system allows for Vehicle-to-Grid (V2G) and Vehicle-to-Home (V2H) capabilities, while a high-efficiency DC-DC converter system with Maximum Power Point Tracking (MPPT) guarantees efficient solar energy usage. To extend battery life and avoid overcharging or deep discharge, the on-board BMS, in conjunction with sophisticated logic-based charge control, controls State of Charge (SOC), State of Health (SOH), and thermal stability. By displaying steady charging voltage and current waveforms, effective energy distribution, and seamless power transitions between sources, MATLAB Simulink models show how successful the system is. This hybrid system offers an economical, scalable, and grid-supportive EV charging option, guaranteeing long-term viability in transportation networks powered by renewable energy.
