Core Viewpoint - The implementation of vehicle-to-grid (V2G) technology in China is entering a new phase with the launch of pilot projects in nine cities, showcasing the potential for electric vehicles to interact with the power grid and contribute to energy management [1][2]. Group 1: Vehicle-to-Grid Technology - Vehicle-to-grid (V2G) technology allows electric vehicles to act as mobile energy storage units, charging during off-peak hours and discharging during peak hours, thus aiding in energy consumption and alleviating grid pressure [1]. - In Shanghai, a smart charging network with a capacity of 300,000 kW and V2G discharge capability of 20,000 kW has been established, demonstrating the practical value and potential of V2G technology [1]. Group 2: Challenges and Solutions - Many electric vehicles currently lack reverse charging capabilities, and the high cost of V2G charging station construction limits widespread adoption [2]. - Addressing concerns about battery safety and lifespan due to frequent charging and discharging is crucial for encouraging participation from electric vehicle owners [2]. - Innovative solutions, such as a new control module for retrofitting old charging stations, have been implemented in 19 locations in Shenzhen, saving hundreds of thousands of yuan in renovation costs [2]. Group 3: Growth of Charging Infrastructure - By the end of 2024, the total number of charging facilities in China is expected to reach 12.818 million, a year-on-year increase of 49.1% [3]. - The average utilization rate of public charging stations remains low, highlighting the urgency to optimize resource allocation and ensure that the growing number of charging stations is effectively utilized [3]. - Projections indicate that by 2030, the number of electric vehicles in China could exceed 100 million, potentially providing around 1 billion kW of grid adjustment capacity [3].
