In the context of Energy Internet, as the technical core and main terminal of integrated energy system （IES）, the penetration rate of electric vehicle （EV） has been rapidly improved, and the coupling between transportation and energy network has been enhanced. The charging and swapping facilities for IES with EV high penetration will become an important carrier and effective way to deepen the development of energy transportation integration system. Firstly, the energy transportation integration system is analyzed and described, and then the centralized charging and unified distribution swapping pattern for IES with EV high permeability is summarized from different dimensions such as theory, model, and practice. Secondly, the technical performance, key characteristics, key scientific problems and challenges of EV high permeability IES oriented switching network are summarized and analyzed. Finally, the paper looks forward to the problems that need to be solved urgently in the operation and planning of the power exchange network for IES under the high penetration load environment of EV in the future, which provides reference for future research.
