摘要

在过去的十年中,交通电气化已成为这篇文章的核心重点。电动汽车(EV)逐渐在市场上占据一席之地,取代了传统的内燃机汽车。电动汽车的普及导致充电站数量的相应增加,从而对电网(PG)产生了重大影响。目前正在设计各种充电策略和电网集成方法,以减轻电动汽车充电的潜在负面影响,同时优化电动汽车与电网集成的优势。本文全面概述了电动汽车市场、标准、充电基础设施的现状,以及电网对电动汽车充电影响的应对措施。文章全面评估了电动汽车技术即将取得的进步,包括联网汽车、自动驾驶和共享交通,将如何对电动汽车与公用事业的整合产生错综复杂的影响。文章最后细致分析并总结了电动汽车充电基础设施和电网整合未来发展所面临的挑战和相关建议。风险资本对电动汽车和电池技术新兴企业的投资激增,到 2022 年将达到近 21 亿美元。与 2021 年的数字相比,这一显著增长代表着 30% 的大幅增长。此外,这些投资主要集中在两个关键领域:电池技术的进步和关键矿物的收购。这种投资趋势的明显变化突出表明,人们日益认识到电动汽车和电池技术创新的战略重要性和潜在盈利能力。2022 年,全球用于电动汽车的支出将超过 4250 亿美元,与上一年(2021 年)相比大幅增长 50%。值得注意的是,这些支出中仅有 10% 来自政府支持,大部分来自消费者投资。

Global Trends in Electric Vehicle Battery Efficiency and Impact on Sustainable Grid
Over the past decade, transportation electrification has emerged as a pivotal focus of the article. Electric vehicles (EVs) have progressively gained traction in the market, displacing conventional internal combustion engine vehicles. This surge in EV popularity has led to a corresponding increase in the number of charging stations, thereby significantly influencing the power grid (PG). Various charging strategies and grid integration approaches are being devised to mitigate the potential negative impacts of EV charging while optimizing the advantages of integrating EVs with the grid. This paper provides a comprehensive overview of the current state of the EV market, standards, charging infrastructure, and the PG’s response to the impact of EV charging. The article provides a comprehensive assessment of how forthcoming advancements in EV technology, including connected vehicles, autonomous driving, and shared mobility, will intricately influence the integration of EVs with the PG. Ultimately, the article concludes by meticulously analyzing and summarizing both the challenges and recommendations pertinent to the prospective expansion of EV charging infrastructure and grid integration. The proliferation of venture capital investments in nascent start-up ventures specializing in EV and battery technologies has experienced a pronounced surge, reaching an impressive sum of nearly USD 2.1 billion in 2022. This notable increase represents a substantial uptick of 30% compared to the figures recorded in 2021. Furthermore, these investments have been directed towards two key areas: advancements in battery technology and the acquisition of critical minerals. This discernible shift in investment trends underscores the growing recognition of the strategic importance and potential profitability associated with innovations in EV and battery technologies. In 2022, global expenditures on EVs surpassed USD 425 billion, marking a substantial 50% increase compared to the previous year, 2021. Remarkably, a mere 10% of these expenditures can be attributed to governmental support, with the bulk stemming from consumer investments.
