公交车变身城市“充电宝” 反向放电“新”举措助力高温电力保供

Core Viewpoint - The article discusses the innovative approach taken by Chengdu's public transportation system to alleviate electricity pressure during high-temperature periods by utilizing electric buses as power sources for the grid [1][3]. Group 1: Electric Bus Initiative - Chengdu's public transportation has implemented a "vehicle-to-grid" project, allowing buses to discharge their remaining electricity back to the grid during peak demand times [3][5]. - Each bus can store over 300 kWh of electricity, and after daily operations, they typically have around 100 kWh of surplus energy available for discharge, equivalent to the daily electricity consumption of about 10 households [5][6]. Group 2: Infrastructure and Support - The Chengdu public transport system has established two demonstration stations equipped with 52 bidirectional smart charging and discharging terminals, enhancing the efficiency of energy use and supporting social electric vehicle charging needs [8]. - This initiative not only addresses high-temperature challenges but also promotes the effective utilization of green energy [8]. Group 3: Benefits and Convenience - The project allows for convenient charging for electric vehicle owners, reducing wait times typically associated with public charging stations, as buses can directly charge smaller vehicles [10]. - The flexibility and extensive coverage of the 7,000 buses in Chengdu enable them to act as mobile power sources, providing emergency power supply during significant events or natural disasters [6].
