电动汽车可以连接到电网以提供辅助服务，如频率调节，调峰和旋转储备的想法是引人注目的，特别是在传统形式的存储，备份或峰值供应不可用或昂贵的司法管辖区。自概念提出以来，车辆到电网运营的经济可行性一直是辩论的主题。大多数以前的研究的一个共同缺点是在商业模式的发展中对锂离子电池退化的适当考虑。最近，发表了关于V2G可行性的论文，其中对电池退化的详细描述导致了两个表面上相互矛盾的结论。在本文中，这两项主要研究的作者通过明确管理电池退化的方法如何可靠地延长电池寿命，共同协调了他们之前的结论。本文还回顾了更好地管理车辆和电网应用中电池使用的相关技术和政策影响。
The idea that electric vehicles can connect to the electric grid to provide ancillary services, such as frequency regulation, peak shaving and spinning reserves is compelling, especially in jurisdictions where traditional forms of storage, back-up or peak supply are unavailable or expensive. Since conception, the economic viability of vehicle-to-grid operations has been the subject of debate. A common shortcoming of most of the previous studies has been a proper accounting of Lithium-ion battery degradation in the development of business models. Very recently, papers on the viability of V2G were published for which the detailed account of battery degradation resulted in what appeared to be two ostensibly contradictory conclusions. In this paper, the authors of these two major studies jointly reconcile their previous conclusions by providing clarity on how methodologies to manage battery degradation can reliably extend battery life. The paper also reviews the associated technology and policy implications of better managing battery use in vehicle and electrical grid applications.
