Abstract

Disruptions to electric vehicle charging infrastructure can hinder consumers’ confidence and impact the performance of shared electric vehicle (SEV) systems. This study focuses on SEV systems’ vulnerability to emerging cyberattacks at the system level utilizing city-scale SEV trajectory data in Beijing, China. A data-driven simulation model is developed to account for realistic charging demand–supply interactions extracted from the data. The results show that among different types of disruptions, cybersecurity threats present unique challenges to SEV systems. Compared with attacking the most highly utilized charging stations, attacking popular ones on the city’s outskirts is more likely to significantly increase stress on the charging infrastructure and reduce the accessibility of SEVs. Meanwhile, the interactions between SEVs and infrastructure could either amplify the impacts by triggering cascading failures or relieve the adversarial effects. These findings provide insights into designing policies and solutions to enhance the resilience of SEV systems against cyberattacks.

数据驱动的共享电动汽车系统网络攻击脆弱性分析

电动汽车充电基础设施的破坏会阻碍消费者的信心，并影响共享电动汽车（SEV）系统的性能。本研究利用中国北京城市规模的共享电动汽车轨迹数据，重点研究共享电动汽车系统在系统层面面对新兴网络攻击时的脆弱性。研究开发了一个数据驱动的仿真模型，以考虑从数据中提取的现实充电供需互动。研究结果表明，在不同类型的破坏中，网络安全威胁对 SEV 系统提出了独特的挑战。与攻击使用率最高的充电站相比，攻击城市郊区的热门充电站更有可能显著增加充电基础设施的压力，并降低 SEV 的可用性。同时，SEV 与基础设施之间的相互作用既可能通过引发连锁故障来扩大影响，也可能缓解对抗效应。这些发现为设计政策和解决方案提供了启示，以增强SEV系统抵御网络攻击的能力。

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
