Abstract: Objective With the accelerated advancement of low-carbon and digital transformation of transportation Energy, the Vehicle Terminal-Integrated Energy Station (VT-IES) serves as an important hub supporting green transportation and intelligent energy. It is gradually becoming the focus of attention in both the academic and industrial circles. A systematic review of the research context and technological evolution characteristics in this field can help reveal the intrinsic connections among research paths, distill core technologies, and explore sustainable optimization directions. Methods In this paper, CiteSpace was employed, and the relevant research literature of VT-IES at home and abroad from 2015 to 2024 was taken as the data source. The methods of keyword co-occurrence, clustering and timeline evolution analysis were adopted to visualize and summarize in detail the research hotspots, frontier themes and development trends in this field. Results A comparative analysis of research achievements at home and abroad shows that international research places more emphasis on system modeling and multi-objective optimization in the field of VT-IES, forming a relatively mature technical system. Especially in cutting-edge methods such as robust control, stochastic optimization, and deep reinforcement learning, rich experience has been accumulated, which can better deal with system scheduling problems in complex and uncertain environments. Domestic research, on the other hand, is more driven by application scenarios, with a focus on the layout of charging piles, the coordinated scheduling of the charging and discharging process of electric vehicles and demand response, which has promoted the practical application of VT-IES in urban transportation and regional energy systems. Furthermore, from the perspective of the evolution trend, the technical system in this field is presenting multi-dimensional development characteristics: First, multi-energy collaborative dispatching has become a core issue; second, the deep integration of transportation scenarios and energy systems; third, intelligent regulation and control methods are gradually penetrating. Conclusion The related research on VT-IES has formed a differentiated development pattern both internationally and domestically. The advantage of international research lies in the completeness of its methodology and theoretical system, while the characteristic of domestic research is its close alignment with local application scenarios. In the future, we should draw on international advanced experience, combine the actual needs of China's transportation energy transformation, and build a research framework oriented towards multi-energy complementarity and intelligent optimization, so as to promote the efficient, clean and innovative development of the transportation energy system.
