Original abstract

An EV charging station that uses solar panels, batteries, and utility company assistance is proposed in this paper. By doing so, we can build a charging infrastructure that is permanent, dependable, and always on. One way to manage energy use is via a hybrid system that combines photovoltaic (PV) cells, a BESS, and a two-way grid connection. Solar energy is used to directly charge electric vehicles during the sun's peak hours. The utility provider or the battery is credited with any excess energy. When solar power is low or demand is high, the grid and batteries work together to ensure that electricity is always sent where it is required. The utilization of green energy is prioritized and battery charging and discharging are optimized using a sophisticated energy management system (EMS), which facilitates vehicle-to-grid (V2G) connections. To maximize solar power utilization, a bidirectional DC-DC converter and inverter are employed, along with Maximum Power Point Tracking (MPPT). Models run in MATLAB/Simulink reveal the system's efficiency, load balancing capabilities, and power source switching smoothness. The simulations also demonstrate that the system is well-suited for smart charging networks that can withstand the test of time.
