Upgrade Path and Technological Innovation of Integrated Energy Stations in the Context of Global Energy Transition

Currently, the global energy structure is undergoing profound changes, rapidly evolving from a traditional model reliant on single fossil fuels to a new energy system integrating wind, solar, storage, hydrogen, and refueling. Behind this transformation is a significant increase in user demand for convenient, low-carbon, and intelligent energy replenishment, coupled with the dual drivers of "dual-carbon" goals and policies for building a new energy system. The traditional functional positioning and operating model of gas stations are no longer adequate to meet the new requirements of the energy consumption revolution. Against this backdrop, the strategic upgrade of traditional gas stations into integrated energy stations has become an inevitable choice for the industry to achieve sustainable development.

Under the strategic guidance and resource support of China National Petroleum Corporation (CNPC) and Sinopec, Jiulu, together with Shandong University and Shandong Academy of Sciences, formed a collaborative research and development team to tackle the core technological bottlenecks of integrated energy stations. After three years of systematic research, through 127 iterations and optimizations of the solution and more than 50,000 extreme working condition tests, they finally developed a globally leading standardized solution for "integrated intelligent three-dimensional charging stations," providing a replicable technical model for the upgrading of urban charging facilities to three-dimensional and large-scale operation.

The solution is supported by five core technological breakthroughs: First, "horizontal DC fully flexible charging technology" to achieve efficient adaptation and flexible expansion of charging equipment; second, "flexible dual-guided plug-in technology" to improve the stability and safety of charging connections; third, "multi-dimensional three-dimensional fire protection system" to build an active protection network covering the entire charging process; fourth, "interactive terminal integrated technology" to connect the entire chain of services including user operation, energy management and data monitoring; and fifth, "micron-level precise leveling positioning technology for lifting systems" which uses absolute value coding technology to achieve instantaneous precise leveling positioning without the need for reference point addressing.

Notably, the team not only achieved technological breakthroughs but also propelled the development of industry standards—leading the drafting of China's first series of standards for "Three-Dimensional Charging Stations for Electric Vehicles," filling a regulatory gap in the field and providing crucial guidance for the industry's standardized development. This achievement marks China's entry into the global first tier in the field of integrated energy station technology and provides a dual guarantee of "technology + standards" for the low-carbon transformation of traditional energy infrastructure.

This upgrade is not only a technological innovation, but also a key step for CNPC and Sinopec in implementing their "dual-carbon" strategy and laying the groundwork for the future energy ecosystem. Through deep integration of industry, academia, and research, the team precisely matched cutting-edge technologies with industry needs, solving the pain points of limited urban charging space and low efficiency, contributing practical experience to the construction of a new integrated "source-grid-load-storage" energy system, and injecting new momentum into the sustainable development of the industry.
