—Unveiling the “Invisible Guardian” in Extreme Environments

On the Mongolian Plateau, where temperatures plunge to -30°C, a XCMG EV pure electric loader shuttles tirelessly through a coal mining site. Despite the piercing cold, the equipment maintains efficient and stable operation—all thanks to an “invisible technology”: Xinrun’s Intelligent Battery Thermal Management System. Like a precise “temperature steward,” it enables the electric loader to perform flawlessly in both extreme cold and scorching heat, making it a true “endurance champion” in the field of new energy construction machinery.

I. Technological Breakthrough in Extreme Cold

The battery of an electric loader is like the human heart—highly sensitive to temperature. In frigid northern regions, low temperatures can reduce battery activity, slash range, and even prevent startup. Traditional heating methods often involve direct battery heating, which carries overheating risks and high energy consumption. In contrast, Xinrun’s solution employs “intelligent phased temperature control” for precise regulation:

  • Standby Mode:When the battery temperature drops to ≤ -20°C, the system automatically initiates preheating via PTC heaters and hydraulic oil circuits, gradually warming the battery to a safe threshold.
  • Operation Mode: Strategies are dynamically adjusted based on real-time conditions (charging/working). For example, during charging, if the battery temperature is ≤ -10°C, the system prioritizes residual heat from the coolant for heating. If temperatures drop further, a three-stage heating mode ensures charging efficiency and safety. This technology not only resolves cold-start challenges but also extends battery life by over 30%.

II. The “Intelligent Brain” of the Thermal Management System

Xinrun’s system excels in intelligence and efficiency:

1、Multi-Source Heat Integration:

  • Utilizes waste heat from hydraulic oil circuits to heat batteries, reducing energy consumption by 15%.
  • Coordinates cooling circuits and PTC heaters to form a “dual-channel” temperature control network, improving response speed by 40%.

2、Dynamic Balance Algorithm:

Sensors monitor battery and hydraulic oil temperatures in real time, combining environmental data to automatically switch between cooling/heating modes. For instance, in summer heat, the system prioritizes water cooling and reduces charging power to prevent overheating.

  • Redundant Safety Design:

Dual solenoid valves and independent cooling chambers ensure stable operation even if a single component fails, reducing failure rates to below 0.1%.

III. Field Validation: From Northwest China to the Mongolian Plateau

Xinrun’s system has been rigorously tested in XCMG EV electric loaders worldwide:

  • -30°C Challenge in Northwest China: In Xinjiang coal mines, loaders operated continuously for 72 hours, with battery temperatures consistently maintained at 15-25°C and a range retention rate of 98%.
  • 50°C Heat on the Mongolian Plateau: In extreme heat, the system combined “cooling + waste heat recovery” to keep peak battery temperatures below 45°C, preventing thermal runaway.
    User feedback: “We used to worry about power failures in winter, but now Xinrun’s system has turned our equipment into an ‘all-weather warrior.’”

IV. The “Invisible Driver” of the Green Revolution

Xinrun’s ambitions extend beyond technological innovation. As a global leader in thermal management for construction machinery, it aims to achieve full-lifecycle decarbonization for new energy equipment through its “zero-carbon thermal management” solutions:

  • Modular Design: Compatible with electric loaders from various brands, already serving industry leaders like XCMG and Sany.
  • Digital Twin Technology: Cloud-based simulations optimize thermal management strategies, with future plans for “predictive maintenance” to further reduce operational costs.

Conclusion: “Intelligent Manufacturing from China” Behind Endurance

From breaking patent barriers to gaining global recognition, Xinrun’s battery thermal management system is writing a new chapter for Chinese intelligent manufacturing. It is not only the “technical ace” empowering XCMG electric loaders worldwide but also a critical leap toward efficient, safe, and sustainable development in new energy construction machinery. As smart and green technologies continue to integrate, this “invisible monument” will keep fueling the global new energy revolution with relentless momentum.
