1. The V2G charging and discharging system utilizes the electric vehicle's battery as an energy storage device and completes the balance and optimization of power supply and demand between the power grid and electric vehicles through local and remote EMS management systems. It can easily connect with photovoltaic systems and brings application value in peak-valley electricity usage, distribution network expansion, user-side energy storage, and battery monitoring. It can also serve as a core node to achieve the integration of smart grids and supplement user-side energy storage.
2. Intelligent and orderly charging and discharging is a necessary condition for realizing vehicle-grid interaction. The V2G bidirectional charging and discharging technology and the intelligent and orderly charging and discharging system for vehicle-grid interaction are important foundations for grid integration and interaction. The integration and interaction of new energy vehicles and the power grid is an important direction for the development of the charging industry in the next 10 years.
