Eliminating the traditional heavy-truck charging paradigm! Ruisu Intelligent has globally debuted its self-developed 3 MW all-liquid-cooled megawatt‑level fast charger, enabling electric heavy trucks to achieve a full charge in just 20 minutes and sustain six hours of continuous operation.

In 2025, the global new‑energy heavy‑truck market is poised for explosive growth. In China, first‑half sales reached 79,000 units, a year‑on‑year surge of 186%, with market penetration exceeding 20%. However, three major pain points—slow charging, limited infrastructure coverage, and high costs—continue to constrain industry development. In long‑haul logistics, new‑energy adoption remains below 1%, making energy‑replenishment efficiency the central bottleneck. Even more critically, in harsh operating conditions such as extreme cold, scorching heat, and high altitudes, existing ultra‑fast charging stations suffer failure rates as high as 35%, severely impacting the operation of electric heavy trucks. Now, Ruisu Intelligence globally debuts its self-developed all-liquid-cooled 3 MW flash-charging system. , with “ 20 Minute charging  80% , Continuous operation 6 Hour “breakthrough performance, and in” - Extreme environments ranging from -40°C to 70°C Operating stably at the lower end, it directly phases out existing charging equipment below 1.5 MW, officially marking the entry of electric heavy-duty truck charging into “ The Megawatt Ultra-Charging Era ”, pressing the “accelerator” for global new-energy vehicles to achieve equal performance in both fuel and electric modes, and for construction machinery to embrace ultra-fast electric charging.

Ruisu Intelligent’s megawatt‑level flash‑charging solution is based on “ Energy storage cabinet + charging cabinet “…as the core, paired with mobile charging vehicles and an intelligent control system, forming a…” Fixed + Mobile “A dual-mode energy‑replenishment architecture that covers the full spectrum of needs, from basic charging to emergency power‑up.” Building an all-scenario energy-replenishment system 。

In the megawatt‑level flash‑charging system, ① when the charger is not performing a charging operation, the grid supplies electrical energy to the energy storage system, ensuring that the system maintains a fully charged state at all times.

② When a vehicle arrives to charge and the power supplied by the existing PCS and transformer is insufficient to meet its fast-charging requirements, the battery pack will seamlessly join the charging process, working in concert with the PCS and the transformer to deliver the necessary power.

Through this collaborative operating model, power resources can be flexibly allocated, ensuring that vehicles receive a stable and sufficient power supply during fast charging. This significantly reduces charging times, enhances charging efficiency, and delivers a more convenient and efficient charging experience for users.

• Storage The energy cabinet serves as the energy buffer hub of the solution.

  
  

It uses lithium iron phosphate cells, offering long life and high safety. 。 Store energy at lightning speed with megawatt‑level flash charging. In the grid’s peak‑and‑valley periods, the stored energy can be rapidly discharged in seconds via flash charging, precisely bridging electricity demand gaps and truly achieving a closed-loop system of “efficient energy capture – ultra‑fast energy storage – intelligent energy release.”

• Charging cabinet: a high-power, multi-interface energy-replenishment hub.

The charging cabinet consists of a main cabinet and sub-cabinets (liquid-cooled / air-cooled terminals). The main cabinet provides the core power output, while the sub-cabinets are compatible with various vehicle‑type interfaces, forming a “ 1 The Lord is from above “Flexible configuration mode.”
