Recently, the first independent shared energy storage power station in Shanghai's Jiading Industrial Zone – a 50MW/200MWh project – successfully achieved full-capacity grid connection. As one of Shanghai's first large-scale pilot energy storage stations, the project is safeguarded by the Envicool BattCool Energy Storage Full-Chain Liquid Cooling Solution, which delivers efficient and reliable thermal management.

The project pioneers a “LFP + Sodium-ion + Semi-Solid-State Lithium” trinary integration technology route, providing a replicable practical model for regional grid peak-shaving, renewable energy integration, and the sustainable commercial operation of energy storage systems.

Jiading, Shanghai, lies in a subtropical monsoon climate zone, characterized by hot, humid summers and cold, damp winters, with significant temperature fluctuations throughout the year. These conditions pose severe challenges to the environmental adaptability of energy storage systems .

Moreover, the three different battery chemistries – LFP, sodium-ion, and semi-solid-state lithium – impose extremely high demands on temperature control precision and uniformity. Each battery type exhibits distinct heat generation characteristics, and temperature variations directly impact charge/discharge efficiency, cycle life, and system safety. Achieving full-scope precise temperature control across this “trinary integration” architecture became one of the core challenges for successful project deployment.

To meet the stringent temperature control requirements of this hybrid battery configuration, Envicool leveraged its mature product portfolio, extensive project experience, and real-world insights to deliver high-performance solutions that significantly enhanced component compatibility and maximized system reliability.

1. Precision Temperature Control Ensures Battery Consistency

The BattCool Full-Chain Liquid Cooling Solution utilizes real-time cell temperature sensing technology to precisely match the optimal cooling temperature for each battery type, effectively minimizing temperature fluctuations. This provides a fundamental layer of protection for the safe and stable operation of the “trinary integration” hybrid battery system.

2. Wide-Temperature Operation for Year-Round Stability

The BattCool chiller features an ultra-wide operating temperature range, supporting stable operation from -40°C to 55°C. This fully covers Shanghai‘s year-round extreme temperature variations, ensuring that batteries consistently remain within their optimal operating temperature window.

3. Intelligent O&M with Remote Monitoring

The BattCool solution supports remote communication and real-time operational status feedback. Through multiple sensors and monitoring functions, it enables full digital acquisition of operational data. O&M personnel can remotely monitor system status, predict potential faults, and implement preventive maintenance – deeply aligning with the project’s overall digital and intelligent operation philosophy.

4. Rigorous Validation Across Scenarios

From the world's first 100MWh+ digital energy storage power station, to Shanghai's first independent shared energy storage station, and Latin America's largest independent shared energy storage project — the Envicool BattCool Energy Storage Full Chain Liquid Cooling Solution has been validated across multiple benchmark projects worldwide.

Looking ahead, Envicool remains committed to supporting new energy storage systems in achieving safe, efficient, and reliable operation across diverse application scenarios — driven by our innovative and stable thermal management solutions.
