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.

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.
