The General Office of the National Development and Reform Commission and three other government organs jointly released the Notice on Promoting the Scientific Planning and Construction of High-Power Charging Facilities, pointing out the direction for the high-quality development of new-energy vehicle (NEV) charging infrastructure. As clearly stated in the Notice, by the end of 2027, China aims to have more than 100,000 high-power charging facilities nationwide, emphasizing technological innovation, safety management and scenario integration. Duolun Technology, an active advocate of policies, has independently developed a solution that integrates liquid-cooled ultra-fast charging and intelligent energy storage products with photovoltaic power generation, energy storage, charging and inspection, which has won widespread recognition in the industry. It has become a key policy implementer.

Policy document

Overcoming "range anxiety" with response to policy

Strong policy support for high-power charging facilities can help NEV owners overcome "charging anxiety" and "range anxiety". Traditional charging models and conventional fast charging are difficult to meet the efficient energy replenishment requirements for long-distance mobility. Duolun Technology’s solution integrating liquid-cooled ultra-fast charging products with photovoltaic power generation, energy storage, charging and inspection supports efficient charging comparable to refueling a traditional vehicle. At the same time, it stabilizes load fluctuations in the power grid and strengthens clean energy consumption capacity. This marks not only the company’s active response to a policy call for "exploring methods for optimizing power access capacity" but also a vivid practice of constructing an integrated "source-grid-load-storage" power system.

“More than just fast” multidimensional value

Ekingpow, a subsidiary of Duolun Technology, has a core ultra-fast charging product—charging stacks, which, along with the integrated photovoltaic-storage-charging-inspection solution, can flexibly and dynamically distribute high-power direct current to multiple charging terminals. Through the dynamic power scheduling of a centralized power distribution system, it enables multiple vehicles to charge simultaneously and also efficiently interact with the power grid. This product is applicable to heavy-duty trucks, mining vehicles, electric ships, buses and other commercial vehicles, delivering “more than just fast” multidimensional value.

More efficient liquid-cooled ultra-fast charging

The liquid-cooled ultra-fast charging technology allows ordinary electric vehicles to replenish 200 km of range with a 10-minute charge, which significantly increases energy replenishment efficiency and drastically shortens charging time.

Safer liquid cooling

Coolant circulation for heat dissipation can maintain stable temperatures of charging guns and cables and plugs even during long-duration high-power charging, thereby reducing faults or safety hazards caused by overheating.

Greener V2G technology

Owners can make profits after their vehicles transform into "mobile energy storage stations". In case of an electricity supply shortage in the power grid, owners can sell the excess electricity to the power grid, achieving "vehicle-grid interaction and energy sharing".

More reliable battery testing

The built-in testing module in a charging pile can automatically conduct a "health examination" on the battery and generate a battery health report, helping vehicle owners promptly identify potential safety hazards.

Building reputation with strength

The self-developed ultra-fast charging and energy storage products of Ekingpow and AXEnergy have currently been applied in comprehensive energy demonstration stations in Nanjing, Bozhou, Zaozhuang and more. Efficient charging not only brings more earnings for charging stations, but also enables users to truly experience the convenience of the ultra-fast charging technology.

The above products have been successively honored as a Pioneer in Expansion of the Ultra-fast Charging Market in 2024 and one of China’s Top 10 Solutions for PV, Energy Storage and Charging in 2025. It demonstrates Duolun Technology's dual strength in technological innovation and market application.

Duolun Technology, riding on “more than just fast” comprehensive advantages and photovoltaic-storage-charging-inspection integration, rebuilds the NEV charging ecosystem from policy orientation to market demand and from technological breakthrough to user experience. Looking ahead, the company will continually unleash technological value amid the large-scale development of high-power charging facilities, with a view to promoting green transportation.
