Charging Mechanism,System Configuration and Promotion Pathway of Vehicle to Grid for Electric Vehicles
The integration and interaction of electric vehicles(EVs)with energy systems is a crucial factor for the widespread adoption of new energy vehicles and the construction of modern power systems.There is an urgent need to establish a technical system and development path suitable for multi-stakeholder interaction.Based on an analysis of the interaction requirements between battery charging and the energy supply of charging stations,this paper explores charging methods and electrical configurations that accommodate bidirectional interaction between vehicles and energy systems.It proposes mechanisms for ensuring charging safety and prolonging battery life for EVs,and efficient green power absorption electrical architectures for charging stations.The paper elucidates technical solutions for leveraging the large-scale energy storage potential of EVs to support the integration of renewable energy sources.Finally,considering the energy resource endowments and distribution characteristics of electric vehicles in different regions of China,the paper proposes a"point-line-surface"approach with"bottom-up"features for the promotion of vehicle-energy interaction.This approach aims to achieve mutual support and coordinated development between a high proportion of electric vehicles and renewable energy generation.
