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 ...

Core Viewpoint - The implementation of the "Five-Period" time-of-use electricity pricing mechanism in Shandong since 2021 aims to optimize electricity consumption patterns, benefiting both individual consumers and businesses by reducing electricity costs and alleviating pressure on the power grid [1][2][4]. Group 1: Time-of-Use Pricing Mechanism - The "Five-Period" pricing divides the day into five segments: peak, flat, valley, and deep valley, with varying rates to encourage users to consume electricity during off-peak hours [2][4]. - The pricing structure allows for significant savings; for example, deep valley pricing can be as low as 0.222 yuan per kWh, while peak pricing can reach 0.888 yuan per kWh, creating a price difference of up to 90% [2][4]. Group 2: Benefits for Consumers - Individual consumers, such as electric vehicle owners, can save significantly by charging during low-cost periods. For instance, charging during deep valley hours can reduce annual electricity costs to around 600 yuan compared to 1731 yuan without time-of-use pricing [3][4]. - A case study of a consumer switching from gasoline to electric vehicles shows a drastic reduction in annual costs from nearly 12,000 yuan to about 700 yuan due to the adoption of time-of-use pricing [1][3].
