Core Viewpoint - The article discusses the feasibility and challenges of implementing Vehicle-to-Grid (V2G) technology in China, emphasizing the need for collaboration among electric vehicles, charging infrastructure, and the power grid to achieve a successful scale-up of V2G applications [3][5][8]. Group 1: V2G Implementation Challenges - The initial testing of V2G technology began on March 31, with 12 vehicle models and 9 charging stations tested, indicating preliminary feasibility but highlighting the need for regulatory compliance and standardization [5][10]. - Key challenges include establishing a reverse discharge pricing model based on battery data, which is crucial for attracting investment while balancing electricity costs [5][6]. - There is a lack of defined standards for battery discharge power, which could lead to inefficiencies and potential risks to the power grid [6][9]. Group 2: Stakeholder Collaboration - Successful V2G implementation requires breaking down barriers between vehicles, charging stations, and the power grid, necessitating collaboration among various stakeholders, including government, vehicle manufacturers, and charging infrastructure providers [8][10]. - The establishment of a "testing consortium" is proposed to enhance communication and efficiency among different sectors involved in V2G [8][9]. - Financial and insurance sectors are encouraged to participate in V2G initiatives, providing incentives for vehicle owners and creating new revenue streams for insurance companies [9][10]. Group 3: Future Prospects and Policy Recommendations - The article suggests that with increased awareness and technological advancements, vehicle owners' willingness to participate in V2G will grow, enhancing the frequency of vehicle discharges and contributing to grid stability [10]. - It is recommended to develop more refined subsidy policies to motivate vehicle owners and manufacturers to engage in V2G, thereby creating a win-win situation for individuals and society [4][10]. - The need for further testing in various environmental conditions is emphasized to ensure the robustness of V2G technology under different seasonal demands [8][10].
