雷云 毛思哲 新能源车摇身一变，成为城市的"能量银行"。近日，华中地区首个规模化车网互动（V2G）项目在武汉 正式投入运行。这意味着，从此，电动车不仅可以在低谷期充电储能，更能于电网用电高峰时"放电卖 电"赚取收益，同时为城市电网高峰稳定运行注入了可靠的新动能。 创新应用的规模化车网互动（V2G）项目如何让车主受益？8月24日下午，记者来到位于武汉市经开区 的南太子湖超级充换电站，新能源车主秦女士将自己的车接入能够双向充放电的V2G充电桩，在扫码、 点击屏幕确认V2G放电后，她的电动车瞬间化身为"能量银行"，开始向电网反向输送电力。 国网武汉供电公司新能源汽车充换电技术攻关实验室负责人表示，经过测算，新能源车主如果每年参与 30次放电，每次放电30度，总的放电收益就能完全覆盖日常充电成本，相当于实现了"零成本"的绿色出 行。 V2G技术也称车网互动技术，就是把新能源汽车变为"移动充电宝"，在电网负荷低谷时充电储存电能， 在电网负荷高峰或有需要时，将车载电池储存的电能反向输送回电网。 统计数据显示，截至目前，武汉市新能源汽车保有量接近70万辆，占湖北省总量的近60%。国网武汉供 电公司已在武汉市11个充换电场站 ...

Core Viewpoint - The article discusses the growing importance of Vehicle-to-Grid (V2G) technology in enhancing the efficiency of electric vehicles (EVs) and promoting sustainable energy development, highlighting ChargeScape's collaboration with PSEG Long Island as a significant step in this direction [2][4][5]. Group 1: ChargeScape and V2G Technology - ChargeScape, a startup formed by BMW, Honda, Ford, and Nissan, is at the forefront of integrating EVs into the energy grid through V2G technology [2][4]. - The collaboration with PSEG Long Island marks the first time EVs are included in the utility's demand response program, aiming to intelligently manage the charging behavior of over 6,000 EV owners during peak electricity demand [4][7]. - The AI-driven platform by ChargeScape will optimize charging times and intensity, alleviating grid pressure while providing economic incentives to participants [5][7]. Group 2: Benefits and Challenges of V2G - V2G technology can dynamically adjust EV charging to prevent grid overload, thus enhancing grid stability and efficiency [5][8]. - Concerns about battery degradation due to V2G usage are being addressed, with studies indicating that controlled charging can actually prolong battery life [8]. - The potential for reusing retired EV batteries in energy management is highlighted, as these batteries can support the grid during peak demand periods [10][12]. Group 3: Global Implementation and Regulatory Environment - Utrecht has launched the first large-scale V2G car-sharing service in Europe, demonstrating the need for collaboration among automakers, charging infrastructure providers, energy companies, and local governments for successful V2G implementation [15][16]. - Renault has initiated V2G practices in France, emphasizing the need for unified regulations in Europe to unlock the full potential of V2G technology [17]. - In China, while the rapid adoption of EVs is noted, the implementation of V2G technology faces challenges due to differences in market conditions and regulatory environments compared to the US and Europe [18][19].
