充电基础设施:为电气化的未来打下基础

Power comes in many forms. For electric vehicles (EVs), it’s electricity. It sounds simple enough but transitioning a fleet to electrified power takes careful planning and a number of considerations in terms of infrastructure.

It’s easy to get excited about electrified transportation, but an EV ecosystem goes far beyond just placing an order for new vehicles and dropping a few chargers around town. Large-scale charging systems require robust infrastructure planning in tandem with your community or organization’s overall electrification strategy.

Here are five considerations you should make during infrastructure planning, and how to navigate some of the many decisions you’ll face along the way.

Feasibility

While an electrified transportation system is a powerful and effective solution for many cities around the world, fully electrified transit might not be the best choice for every community or every mission just yet.

Technology and infrastructure are advancing rapidly, but some localities may not yet have compatible grid power or electrical infrastructure to support large-scale EV adoption immediately. Even if the grid has enough power to support the electrification at the aggregate level, there can be local limitations and power may not be available at the location it is needed.

Similarly, the duty cycle of the mission can provide additional challenges. Consider conducting a feasibility study to see what the limitations will be, if any, should your town, city, or organization pursue electrified transportation. It can be helpful to get a third-party reality check to make sure your electrified ambitions are achievable with your community’s resources.

Even if there are challenges on the path of large-scale electrification, you’ll likely be able to start making infrastructure improvements and create a long-term plan to get your community to where it needs to be to support electrified transportation with some of the following considerations. 

硬件

One of the first considerations in building out an electrified transportation system is your charging infrastructure — the nuts and bolts delivering power to your EV fleet. This includes the substation, power box, and charging unit. There are a lot of options currently out in the market, and a trusted advisor can help you navigate the many choices you’ll have for chargers and other hardware needed.

By examining your fleet, your city’s layout, existing infrastructure, and power availability, you’ll begin the process of deciding what chargers work best for your electrification strategy. But it goes beyond just selecting what chargers to buy — you’ll need to determine where they’ll be located, whether vehicles should charge fast or slow, what time vehicles will be charged, and more.

All of these decisions must be taken into consideration when selecting your fleet of EVs as well. Because of the complicated nature of planning, it’s helpful to bring on a full-service partner with experience strategizing all elements of your electrification journey — from chargers to vehicles and beyond.

Routes

Route planning is another key aspect of infrastructure consideration for adopting an electric fleet. Not only do you need to decide if and where chargers will be placed along routes (as opposed to only in a charging depot), but where your electric vehicles will drive.

Though EV range is rapidly improving, transit authorities and city planners must accommodate for the potentially limited range of EVs compared to that of vehicles powered by an internal combustion engine (ICE). But this can rapidly become a chicken-and-the-egg situation: Should you purchase your fleet based on your route requirements, or should you adjust your route requirements based on your chosen vehicles?

Oftentimes, it’s a bit of both. That’s why route planning can be so complicated, and often requires an outside expert familiar with many vehicle models and their performance. It’s important to select a trusted manufacturer with a proven history of reliability, so your fleet can perform at its projected range and keep planned routes on track.

Grid power

A locality’s grid power puts the E in EV. To power an electric fleet, you need sufficient and reliable electricity. When planning your electrification infrastructure, evaluate the grid power and determine what kind of chargers and the quantity of EVs they can support — and when and where. The grid power your fleet will need will depend on the size of the battery in the vehicle, the energy requirement for the next day’s mission, and the available time for the charging event. 

Charging times can have a major impact on the overall cost of charging and will influence infrastructure design route planning as well. It may work best to charge your entire fleet overnight in a depot, or your grid power may better support staggered charging throughout the day, either in a depot or on route. Additionally, alternative charging strategies such as the use of microgrids can help reduce the amount of grid power required, and therefore the cost — though they also come with higher initial costs. 

Strategic planning

One of the most complicated aspects of planning for the transition to electrified power is that many of these decisions must happen in tandem with one another. Electrification isn’t a linear process, and it’s important to find a trusted partner well versed in all areas of consideration, as planning and implementation both are lengthy investments in terms of time and finances.

车队的未来:电气化的四个关键-第4部分

车队零排放的未来

在电池电动车辆方面,商用车部门有四个关键的应用。在 四部分博客系列 的4部分中,我们着眼于新技术必须克服的最后一个障碍:政策和法规。

在这第四个预览博客中,我们将探讨如何在与行业和机构的合作中仔细开发商用电动车的政策和法规。毕竟,可持续发展并非仅限于任何一个部门,而且只有借助电动汽车技术、基础设施和经济专家的洞察力,以及终端用户和其他政策制定者,才能成功地制定出通过的激励措施。

如果您首次阅读此系列,您可以在此处找到 第一个零件 此处的第二部分 三部分.

监管担保人

找到正确的重点将需要在整个移动空间内与利益相关方进行持续的对话、咨询和协作。这里的航线范围广泛:长期的零污染目标将为行业的总体发展方向设定条件;跨行业工作小组将制定成熟的技术标准;为基础设施的推出而提供资金并消除障碍的政策将在可用性方面取得进展;投标合同中的可持续发展规定将展示经济可行性,并为可持续车辆创造市场;数据共享方面的协作性工作将提高监测和效率;将税率与排放挂钩将有助于提高投资回报率。

尽管选择的范围令人望而生畏,但世界各地已经出现了一些最佳实践的例子。例如,来自环境研究小组白罗纳的一份 最新报告 详细说明了一些政策举措的性质,这些措施已经在建设中看到了积极成果,目前占全球二氧化碳(CO2)排放的23%。

例如,在挪威首都奥斯陆,该市的市政开发人员采取了一系列举措,旨在为投标人订立投标合同的最低标准。开发人员采取了 "可以在电动上运行的电力" 的政策,为电气化建筑设备的市场创造了潜力。展望未来,该市预计,到2025,所有公共建筑工地都将运营无排放机械和运输。

奥斯陆倡议的成功的一部分,除了利益相关方决心使其发挥作用之外,还可能采用其政策的措辞。通过使用 "可以在电动上运行的" 这一措辞,城市避免迫使建筑公司采取不恰当的方式(例如电气化不适合电气化的产品),并与他们展开对话,讨论哪些可以和不能通电,携手合作,实现可持续性方面的进展。

将其汇集在一起

在世界各地,通过辛勤工作,将电动汽车的技术能力提升到符合商业应用要求的水平,取得了长足的进步。

这要求我们了解他们的基础设施要求,并明确采取措施,将其总拥有成本降至与传统车辆竞争和超过常规车型的水平,并制定就驱使其通过的政策。

对于康明斯来说,找到正确解决方案的过程始终是一项合作性工作。正确理解意味着在行业和政策的利益相关方以及终端用户之间进行对话,以便深入了解问题并确保成功推出。

车队的未来:电气化的四个关键-第3部分

电气化电力-车队的未来-经济现实 BP 3

在电池电动车辆方面,商用车部门有四个关键的应用。在我们的 四部分博客系列 的3部分中,我们研究了新技术必须克服的第三个障碍:经济可行性。

 

目前,EVs 通常比传统动力当量更昂贵。造成这种情况的一个原因是固有的材料成本,电池制造需要大量的锂。然而,随着工艺的改进、效率的提高和结垢的增加,锂离子(Li)电池的制造成本有望减少,而此成本的降低将成为早期商用电动车(EVs)采用的主要推动力。

在 " 车队未来的 " 白皮书预览系列的第三部分中,我们将研究电气化的经济考虑。如果您首次阅读此系列,您可以在此处找到 第一个零件 第二部分.

经济现实

如今,参与车队管理的任何人都熟悉购买商用车所涉及的经济决策。它可以大致分为资本支出(车辆和基础设施的前置成本)、运营费用和运行车辆的日常成本,例如燃料和维护要求。

EV 的采用可能涉及大量支出,这取决于应用的不同而有所不同。虽然可以为某些商用车车队(例如最后一英里的送货车)提供更多的路边充电点,但对于巴士等其他应用,则需要拥有基础设施。事实上,新的电力车队可能需要全新的建筑物配置。不过,可以共享充电点,这意味着可降低前期成本。通过这种方式,大型电气化项目可以比较小的项目提供更好的投资回报。

从运营的角度来看,两个主要的成本领域是能源和维护。电动汽车的能源成本取决于电力价格,因为如今的燃料成本最终取决于石油价格。通过使用远程信息处理来监测磨损并准确预测何时需要维修,维护成本可能会降至最低。

虽然主要的资本支出显然涉及,但通过将价格随着时间的推移而降低,以及通过共享充电点的车辆节省效率,电动车可以--而且在运输卡车方面已经与柴油选择具有经济竞争力。

政策和法规对商用车的电气化有何影响?在下周的 "车队的未来" 博客系列中找到。
