Core Insights - The article discusses the implementation of Vehicle-to-Grid (V2G) technology in Changzhou, Jiangsu Province, where electric vehicles (EVs) can discharge power back to the grid during peak demand times, benefiting both the vehicle owners and the electricity grid [1][2]. Group 1: V2G Implementation - Changzhou is the only city in Jiangsu to be selected for the first batch of V2G pilot projects, which were announced by the National Development and Reform Commission and other departments in April 2025 [1]. - The V2G system allows EV owners to charge their vehicles during low electricity price periods and discharge power back to the grid during high price periods, effectively acting as a "power bank" for the grid [1]. Group 2: Charging and Discharging Patterns - Research by the State Grid Changzhou Power Supply Company indicates that residential EVs are primarily parked from 6 PM to 8 AM, coinciding with peak electricity demand, while office parking lots see high vehicle occupancy during daytime hours [1]. - A charging strategy called "valley charging + peak discharging + midday replenishment" has been designed to optimize energy use, utilizing solar power during the day and discharging during evening peak hours [1]. Group 3: Economic Benefits for Users - Users like Ms. Li have reported significant financial benefits from participating in the V2G program, with daily earnings from discharging power exceeding their charging costs, leading to a net gain of approximately 7 yuan per day [2]. - The operational model for V2G stations, such as the one at Xingxing Charging New Bridge Park, involves revenue-sharing with local streets and benefits from local subsidies, ensuring a reasonable investment return period [2].
