Electric Vehicle (EV) Adoption is accelerating across the United States, driven by consumer demand, public policy at all levels of government, and industry commitments to electrification. As a result, more than 50% of all new car sales are forecast to be electric by 2030. This article provides a snapshot of how Portland General Electric Company (PGE), a leading investor-owned utility based in Portland, OR, USA, is preparing for the increase in demand from EVs on the power grid.
在消费者需求、各级政府公共政策和行业对电气化的承诺的推动下,电动汽车(EV)在美国的普及正在加速。因此,到2030年,预计超过50%的新车销量将是电动汽车。本文简要介绍了波特兰通用电气公司(PGE)是一家位于美国俄勒冈州波特兰市的领先投资者所有的公用事业公司,该公司正在为电网中电动汽车需求的增长做准备。

Costa Rica is internationally recognized for its fight against climate change. In 2019, the country launched its National Decarbonization Plan (NDP), presenting concrete actions in the short, mid, and long terms to reach net-zero greenhouse gas (GHG) emissions by 2050. The decarbonization of the transport sector is critical to meet this target as it accounts for more than 50% of the country’s net emissions. Plus, it can benefit from its nearly 100% renewable electricity system and its abundant renewable sources to feed the future energy demand for transportation, thus increasing energy independence.
哥斯达黎加在应对气候变化方面的努力得到了国际上的认可。2019年,中国启动了《国家脱碳计划》,提出了到2050年实现温室气体净零排放的短期、中期和长期具体行动。交通运输部门的脱碳对于实现这一目标至关重要,因为它占该国净排放量的50%以上。此外,它可以从其几乎100%的可再生电力系统和丰富的可再生能源中受益,以满足未来交通运输的能源需求,从而提高能源独立性。

Making electric vehicles and the grid work together: A necessity for sustainable mobility [Editors’ Voice] 让电动汽车和电网协同工作:可持续移动的必要条件[编辑之声]

The residential energy landscape is undergoing rapid transformation. In 2022, a record 700,000 U.S. homeowners installed solar, while nearly one in 10 cars purchased in the United States was an electrical vehicle (EV) ( Figure 1 ). In California, recent legislative reform incentivized the installation of home battery storage systems for load shifting, while Senate bill SB 233 requires that all EVs are capable of bidirectional charging. The bill was also designed to reverse a troubling trend: In recent years, Californians have increasingly responded to power outages and rolling blackouts by purchasing diesel-propelled backup generators. In contrast, some EV batteries now have the ability to power a home for up to three days and so are considered a “green” alternative to diesel generators. Federal Energy Regulatory Commission Order No. 2222 has also increased the competitiveness of distributed energy resources (DERs) by enabling them to participate in regional wholesale markets through aggregations. Indeed, commercial equipment combining bidirectional EV charging and solar energy conversion that fully integrates with home battery storage can be leveraged as DERs. This can significantly improve grid reliability, while deferring costly infrastructure upgrades and enhancing decentralized resiliency by powering homes during blackouts.
住宅能源格局正在经历快速转型。2022年,创纪录的70万美国家庭安装了太阳能,而在美国购买的汽车中,近十分之一是电动汽车(EV)(图1)。在加州,最近的立法改革鼓励安装家庭电池存储系统来转移负荷,而参议院法案SB 233要求所有电动汽车都能够双向充电。该法案还旨在扭转一个令人不安的趋势:近年来,加州人越来越多地通过购买柴油驱动的备用发电机来应对停电和轮流停电。相比之下,一些电动汽车电池现在能够为一个家庭提供长达三天的电力,因此被认为是柴油发电机的“绿色”替代品。联邦能源管理委员会第2222号命令也提高了分布式能源(DERs)的竞争力,使它们能够通过聚合参与区域批发市场。事实上,将电动汽车双向充电和太阳能转换与家用电池存储完全集成的商用设备可以作为DERs加以利用。这可以显著提高电网的可靠性,同时推迟昂贵的基础设施升级,并通过在停电期间为家庭供电来增强分散的弹性。

I Charge, Therefore I Drive: Current State of Electric Vehicle Charging Systems 我充电,所以我开车:电动汽车充电系统的现状

I charge, therefore I drive. Is this the new paradigm? The ambitious goals set by governments worldwide to phase out gasoline-powered cars are the driving force behind the upgrade of electric vehicle (EV) charging infrastructures. The EV industry and roadways departments may be asked to invest more in wireless charging, that is, without the need for any cable. Transmitter pads that can charge the EV in the garage, or even briefly at traffic lights, may convey the stationary wireless charge, whereas coils embedded into roadways may power EVs as they drive overhead. The standardized wireless charge appears to be the optimum solution to placate the anxiety of drivers.
我冲锋,所以我开车。这是新的范例吗?世界各国政府制定了逐步淘汰汽油动力汽车的宏伟目标,这是电动汽车充电基础设施升级背后的推动力。电动汽车行业和道路部门可能会被要求加大对无线充电的投资,即不需要任何电缆。可以在车库给电动汽车充电的发射台,甚至可以在交通灯处短暂充电,可以传递静止的无线充电,而嵌入道路的线圈可以在电动汽车在头顶行驶时为其供电。标准化的无线充电似乎是缓解司机焦虑的最佳解决方案。

Buckle up: Electrification of transport is happening [In my view] 系好安全带:交通电气化正在发生[在我看来]

The electrification of demand is a global trend that is gaining momentum as countries take action to address climate change and decarbonize the energy system. To be effective as a decarbonization action, it involves two parallel tracks: shifting energy demand from fossil fuels to electricity and increasing renewable energy grid integration. Together, these parallel tracks form the cornerstone of many countries’ climate action plans. The past decade has seen strong progress in some countries in the grid integration of renewables. This progress and the promise to further increase renewables on the grid opens up the opportunity to decarbonize sections of our whole energy system via electrification.
随着各国采取行动应对气候变化和使能源系统脱碳,需求电气化是一种全球趋势,势头正在增强。作为一项有效的脱碳行动,它涉及两个并行的轨道:将能源需求从化石燃料转向电力,并增加可再生能源电网的整合。这些平行的轨道共同构成了许多国家气候行动计划的基石。过去十年,一些国家在可再生能源并网方面取得了巨大进展。这一进展以及进一步增加电网可再生能源的承诺,为通过电气化使我们整个能源系统的各个部分脱碳开辟了机会。

Korea has deployed various charging infrastructure, from multiple-outlet ultrafast dc charging stations to built-in metering ac outlets, to relieve range anxiety and improve accessibility. The Korean government raised electric vehicle (EV) and renewables targets to realize carbon neutrality by 2050. The government is also making efforts to utilize EV batteries as a flexible resource to help with the grid connection of massive renewables. Time-of-use (TOU) tariffs and a demand response (DR) program have been introduced to facilitate more daytime charging from photovoltaic (PV) generation and reduce solar curtailment. An ac vehicle-to-grid (V2G) system is also a reality and is being applied to mass produce EVs, and demonstrations are underway. As the introduction of more EV models and the supply chain normalize, EV sales will increase rapidly. Consequently, now is the time for Korea to prepare for and fully embrace a more grid-friendly charging infrastructure for the future.
韩国已经部署了多种充电基础设施,从多插座超快直流充电站到内置计量交流插座,以缓解里程焦虑并改善可达性。韩国政府为了到2050年实现碳中和,提高了电动汽车(EV)和可再生能源的目标。政府也在努力将电动汽车电池作为一种灵活的资源,帮助大规模可再生能源并网。引入了分时电价(TOU)和需求响应(DR)计划,以促进光伏发电(PV)在白天充电,减少太阳能弃电。交流车辆到电网(V2G)系统也已成为现实,并正在大规模生产电动汽车,并正在进行示范。随着更多电动汽车车型的推出和供应链的正常化,电动汽车销量将迅速增长。因此,现在是韩国准备并全面拥抱未来更友好的充电基础设施的时候了。

Electric Vehicles (EVS) are not hype. They are here to stay as a critical component in the decarbonization of our transport. According to the International Energy Agency, from 2017 to 2022 alone, EV sales (battery and plug-in hybrids) went from 1 million to more than 10 million. In 2022, 14% of all new cars sold globally were electric. In China, where half of the world’s EVs reside, the share of EVs in total car sales reached 29% in 2022. In Europe, the second largest market, more than one in every five cars sold was electric. In the United States, the share of EVs in total car sales reached almost 8%. With more EVs, of course, comes more electricity demand. This means we also need to ensure that EVs and the grid, particularly the distribution grid, can work together.
电动汽车(EVS)并非炒作。它们将作为我们交通运输脱碳的关键组成部分留在这里。根据国际能源署的数据,仅从2017年到2022年,电动汽车(电池和插电式混合动力车)的销量就从100万辆增加到1000多万辆。2022年,全球销售的新车中有14%是电动汽车。在拥有全球一半电动汽车的中国,电动汽车在汽车总销量中的份额在2022年达到29%。在第二大市场欧洲,每五辆售出的汽车中就有超过一辆是电动汽车。在美国,电动汽车占汽车总销量的比例接近8%。当然,随着电动汽车的增加,电力需求也会增加。这意味着我们还需要确保电动汽车和电网,特别是配电网能够协同工作。
