Energy Storage Cooling Solution in Practice

What is an Energy Storage Cooling System?

An energy storage cooling system is a thermal management solution designed to maintain safe and efficient operating temperatures in battery energy storage systems (ESS). Batteries generate heat during charge and discharge cycles, and proper cooling is critical to prevent thermal runaway, ensure cell consistency, and extend overall system lifespan.

Cooling methods typically fall into two categories: air cooling and liquid cooling. Air-cooled systems rely on fans and air channels to dissipate heat, while liquid-cooled systems use coolant circulation for higher thermal efficiency.

Dagong ESS integrates both technologies into products such as the 100kWh–144kWh Air-Cooled ESS, 215kWh Liquid-Cooled ESS, and 3.35MWh Liquid-Cooled ESS Container, ensuring optimal performance for various scales of energy storage projects.

Challenges for Energy Storage Cooling Systems

As energy storage capacities increase, maintaining temperature uniformity across large battery modules becomes more complex. Air cooling may struggle in high-density systems, leading to uneven cell temperatures and accelerated degradation.

Liquid cooling, while more efficient, involves greater system complexity, potential leakage risks, and higher costs. The key challenge lies in balancing thermal efficiency, cost-effectiveness, and reliability—especially in large-scale or high-power ESS installations.
