Recently, the integrated wind-solar-storage-charging smart energy demonstration project invested and constructed by Duolun Technology has officially started operation, marking the first integrated wind-solar-storage-charging smart charging station in Nanjing Jiangning Hi-Tech Development Zone. Its completion represents Duolun Technology’s proactive practice in building new energy systems and signifies the company’s official completion of a product ecosystem closed loop in the new energy industry track.

Innovative Model

Integrated Wind-Solar-Storage-Charging Demonstration Charging Station

The smart energy demonstration project built by Duolun Technology adopts a “wind-solar-storage-charging” design concept, integrating distributed photovoltaic power generation technology, “peak shaving and valley filling” efficient energy storage, and intelligent fast charging among other cutting-edge technological functions. By combining wind energy, solar energy, energy storage devices, and an energy management control system, it achieves multi-energy complementarity, stable and efficient energy use, and green environmental protection.

Unlike traditional charging stations, this integrated energy demonstration station is powered by cost-effective renewable energy generated from wind and solar sources, equipped with an energy storage system to enhance the stability of new energy stations. Through the coordinated operation of the new energy system, it effectively improves the absorption rate and capacity support capability, achieving local consumption of photovoltaic green electricity, reducing energy costs, and yielding both environmental and economic benefits.

Product Innovation

Visualized, Intelligent, Unmanned Energy Management

The integrated energy demonstration station includes 9 charging spots, with energy storage devices, charging equipment, and management platforms all independently developed by subsidiaries of Duolun Technology. The project is equipped with one Aks intelligent liquid-cooled energy storage system, featuring Ekingpow’s split flexible shared charging pile (with three sets of dual-gun terminals), along with one 7KW AC charging post and one 120KW dual-gun DC multimedia charging pile, meeting the simultaneous energy replenishment needs of different vehicle models.

Smart Energy Operation Management Platform

Moreover, all equipment is connected to a smart energy operation management platform based on big data, cloud computing, AI, and other core technologies, integrated with power electronics technology. Duolun Technology can analyze system capacity, peak-valley electricity prices, and load demands to configure optimal charging and discharging strategies, promoting the efficient use of new energy and making energy management visualized, intelligent, and unmanned.

Application Innovation

Seizing the “Dual Carbon” Opportunity to Support a “Low-Carbon” Future

As the contemporary demand for clean energy and the transformation of energy structures becomes increasingly urgent, Nanjing Jiangning Hi-Tech Development Zone is seizing the construction opportunities presented by the “dual carbon” initiative, accelerating the promotion of pilot projects for integrated wind-solar-storage-charging stations in key locations, fostering the innovative demonstration application of high-power efficient DC piles, liquid-cooled energy storage, and other technologies, providing operable, replicable, and promotable experience and practices for the whole China.

The completion of this integrated wind-solar-storage-charging smart energy demonstration project is an innovative practice by Duolun Technology in building a new type of electric power system. Currently, the practical operational model verification related to “wind-solar-storage-charging” is also proceeding in an orderly manner.

In the future, Duolun Technology will continue to increase its R&D investment in the new energy technology sector, extending the experience of the integrated wind-solar-storage-charging smart energy demonstration project to more regions and promoting the application of more innovative technology. Duolun Technology will delve into technical innovation alongside the new energy industry, contributing to a low-carbon future.
