Abstract

This study proposes a novel methodology for planning fast-charging infrastructure for long-haul battery-electric trucks (BETs) in low-traffic flow regions. The research addresses the challenge of early-stage charging infrastructure development and optimally locating fast-charging stations (FCS) in remote areas, with a focus on minimising routing time and ensuring reliability.

The proposed approach integrates a vehicle energy consumption, a non-linear charging optimisation framework, and a queueing model to design an efficient fast-charging station network in Iceland's Reykjavík-Westfjords freight routes under harsh climate and freight conditions.

Findings indicate that larger batteries and higher charging rates significantly reduce additional routing times. Trucks with 540 kWh battery capacity using 500 kW chargers require minimal extra time, averaging 25 min, while trucks with 360 kWh batteries and 350 kW charging rates experience longer delays, averaging 83 min. These results highlight the impact of battery capacity and charging power on route electrification feasibility and suggest potential alignment with freight schedules.

This study provides valuable insights for policymakers and fleet operators to guide fast-charging infrastructure development and prioritise investments, contributing to the broader goal of freight transport electrification. Future research should investigate the potential impact of the derived charging loads on the power grid.

偏远地区恶劣气候条件下长途电动卡车快速充电基础设施优化

本研究提出了一种在低交通流量地区为长途电动卡车（BETs）规划快速充电基础设施的新方法。该研究解决了早期充电基础设施发展和偏远地区快速充电站（FCS）优化定位的挑战，重点是最大限度地减少路由时间和确保可靠性。提出的方法集成了车辆能耗、非线性充电优化框架和排队模型，在恶劣的气候和货运条件下，在冰岛Reykjavík-Westfjords货运路线上设计一个高效的快速充电站网络。研究结果表明，更大的电池和更高的充电率显著减少了额外的路由时间。使用500千瓦充电器的540千瓦时电池容量的卡车需要最少的额外时间，平均为25分钟，而使用360千瓦时电池和350千瓦充电速率的卡车需要更长的延迟时间，平均为83分钟。这些结果突出了电池容量和充电功率对路线电气化可行性的影响，并建议与货运时间表保持一致。这项研究为政策制定者和车队运营商提供了有价值的见解，以指导快速充电基础设施的发展和优先投资，为货运电气化的更广泛目标做出贡献。未来的研究应探讨由此产生的充电负荷对电网的潜在影响。

期刊介绍： eTransportation is a scholarly journal that aims to advance knowledge in the field of electric transportation. It focuses on all modes of transportation that utilize electricity as their primary source of energy, including electric vehicles, trains, ships, and aircraft. The journal covers all stages of research, development, and testing of new technologies, systems, and devices related to electrical transportation. The journal welcomes the use of simulation and analysis tools at the system, transport, or device level. Its primary emphasis is on the study of the electrical and electronic aspects of transportation systems. However, it also considers research on mechanical parts or subsystems of vehicles if there is a clear interaction with electrical or electronic equipment. Please note that this journal excludes other aspects such as sociological, political, regulatory, or environmental factors from its scope.
