高峰放电:白天用电高峰期(如16-24点),电网负荷大、电价高(部分地区可达3元/度),车主通过 V2G桩将车内多余电量反向输送至电网,获取电价差收益。 只听过电网赚消费者的钱,你听过电动车主"卖电"赚电网的钱吗? 据中新网9月26日报道,2025年8月,武汉一位电动车主在南太子湖超级充换电站通过V2G(Vehicle-to- Grid,车网互动)充电桩向电网反向放电,一小时获得60元收益。这一新闻迅速引发热议:电动车主真 的能靠"卖电"赚钱? 随着国家首批车网互动规模化试点城市名单公布,V2G正从实验室走向现实,成为能源与交通融合的关 键突破口。那么,V2G究竟是什么?V2G究竟是黑科技还是商业噱头?它如何运作?其背后的经济逻辑 和战略意义何在? V2G的概念最早由美国特拉华大学教授威廉·凯利(Willett Kempton)在1990年代提出。其核心思想是: 电动汽车不仅是交通工具,更是移动的储能单元。当大量电动车接入电网时,它们可以像分布式电池一 样,在电力需求高峰时向电网供电,在低谷时充电储能,从而实现"削峰填谷",提升电网稳定性与效 率。 然而,受限于电池技术、通信协议和市场机制,V2G长期停留在实 ...
