Core Viewpoint - The event organized by State Grid Changzhou Power Supply Company aims to promote Vehicle-to-Grid (V2G) technology, allowing electric vehicle owners to discharge surplus energy back to the grid during peak hours, benefiting both the grid and vehicle owners [1][2]. Group 1: Event Overview - The event took place from August 28 to 30, covering 27 charging stations across Changzhou, including public, bus-specific, battery swap stations, and residential charging piles [1]. - Participants needed to make prior reservations with charging station operators to discharge energy, ensuring proper metering and connection to the grid [1]. Group 2: Financial Incentives - Electric vehicle owners received a subsidy of 4 yuan for each kilowatt-hour (kWh) of energy discharged back to the grid, while charging during off-peak hours cost less than 0.4 yuan per kWh, resulting in a net profit of approximately 3.6 yuan per kWh for participants [2]. - The event saw significant participation, with 250 participants and a total reverse discharge of 10,051.09 kWh, leading to a total subsidy of 40,200 yuan for the participants [2].
