Research and Realization of V2G Charging and Discharging System for Electric Vehicles

In recent years, the rapid growth of electric vehicles (EVs) has significantly impacted both energy consumption patterns and environmental sustainability. With increasing concerns over energy scarcity and the need for more sustainable energy solutions, the Vehicle-to-Grid (V2G) technology has emerged as a promising approach to address these challenges. This study focuses on the research and realization of V2G (Vehicle-to-Grid) charging and discharging systems for electric vehicles, aiming to promote green and low-carbon development and alleviate the double pressure of energy shortage and environmental protection. The article firstly introduces the principle of V2G technology and its application to the power grid, and then designs the overall architecture, hardware system, and software system of the V2G charging and discharging system for electric vehicles, and tests and verifies the system at the end. The results show that the designed V2G charging and discharging system can effectively realize the two-way interaction of energy between electric vehicles and the power grid, improve the efficiency of energy use, enhance the stability of the power grid, and bring economic benefits to the users to promote the realization of a green low-carbon economy.
