The project adopts Envicool’s BattCool Energy Storage Full Chain Liquid Cooling Solution, including liquid cooling units, liquid cooling pipe systems, and SoluKing coolant. Together, these systems provide solid support for the efficient and stable operation of the power station.

Semi-solid-state lithium battery technology, as the core technology of this project, utilizes a hybrid solid-liquid electrolyte system. While inheriting the high ionic conductivity characteristics of traditional liquid batteries, it increases the cycle life to over 12,000 cycles and enhances overall battery safety.

This technological advantage, combined with the Envicool BattCool Energy Storage Full Chain Liquid Cooling Solution, ensures the efficient and safe operation of energy storage power stations.

Envicool provided 160 BattCool energy storage liquid cooling units for the project

Wuhai City in Inner Mongolia, where the project is located, lies along the Yellow River and features a typical temperate continental climate characterized by dryness, low rainfall, high evaporation, and significant diurnal and seasonal temperature differences—summer temperatures can reach up to 40°C, while winter temperatures can fall below -30°C.

These climatic conditions pose a severe challenge to the environmental adaptability of the energy storage system: the batteries must maintain activity in extreme cold while effectively dissipating heat in extreme heat, and the equipment must also withstand wind and sand erosion to ensure long-term, high-efficiency operation.

These climatic conditions impose severe challenges on the environmental adaptability of the energy storage system: the batteries must remain active in extreme cold while effectively dissipating heat in extreme heat. Meanwhile, the equipment must withstand wind and sand erosion to maintain long-term, high-efficiency operation.

Envicool’s BattCool energy storage liquid cooling units provide a professional temperature control solution tailored to Wuhai’s extreme climate characteristics. The units operate stably within a wide ambient temperature range of -30°C to 55°C, fully covering local extreme temperature variations.

In addition to temperature challenges, the frequent sand and dust weather in Wuhai during spring and autumn also poses a threat to equipment reliability.

High levels of dust and alkaline particles in the air can corrode external structures and internal components. Envicool units utilize corrosion-resistant protection technology, and the radiator features a sand-proof design that effectively prevents dust intrusion, safeguards heat dissipation efficiency, and reduces dust accumulation—significantly lowering the risk of performance degradation caused by blockage.

To date, Envicool has accumulated 15 years of practical experience in energy storage temperature control. Its products have passed CE and UL certifications, enabling localized technical support and compliance assurance for customers worldwide.

As the global energy transition accelerates, energy storage technology has become crucial for balancing the intermittency and instability of renewable energy sources. Envicool will continue its mission of "More Than Cooling," adhering to technological innovation to provide global customers with long-lasting and safe energy storage temperature control solutions.
