Air Cooling vs. Liquid Cooling: The Future of Energy Storage Thermal Management

What is Energy Storage Cooling Technology?

As battery energy storage systems (ESS) evolve toward higher capacities and energy densities, thermal management has become a core factor for performance and safety.
Cooling technology ensures stable operation and prevents overheating or degradation in lithium-ion batteries. Two main methods—air cooling and liquid cooling—are widely adopted.

Types of Energy Storage Cooling Systems

• Air Cooling:
  Air-cooled ESS uses fans or forced airflow to remove heat from battery modules. It’s cost-effective and easy to maintain, ideal for 100kWh–144kWh Air-Cooled ESS and home or commercial storage systems.

• Liquid Cooling:
  Liquid-cooled ESS relies on circulating coolant through heat exchangers or plates. It offers superior thermal uniformity, supporting large-scale systems such as 215kWh Liquid-Cooled ESS, 372kWh Liquid-Cooled ESS, and 3.35MWh Liquid-Cooled ESS Container.

Features and Advantages

Feature	Air Cooling	Liquid Cooling
Cost	Lower	Higher
Efficiency	Moderate	High
Maintenance	Simple	Complex
Temperature Uniformity	±5°C	±2°C
Best Use	Small/medium ESS	Large-scale ESS

Dagong ESS designs combine both methods to optimize safety, lifespan, and thermal efficiency across its product lines.

Applications of Air and Liquid Cooling in ESS

• Residential Systems: Air cooling ensures silent, efficient operation with minimal maintenance.

• Commercial & Industrial Projects: Liquid cooling manages high loads and tight temperature control.

• Utility and Renewable Projects: Large-scale liquid-cooled ESS containers stabilize renewable energy output and grid operation.

Models such as the 5MWh Air-Cooled Container ESS and 3.35MWh Liquid-Cooled ESS Container demonstrate how hybrid cooling systems can serve diverse energy needs worldwide.

Price of Energy Storage Cooling Systems

The cost of an ESS cooling system varies depending on system size, capacity, and cooling technology. Generally, liquid cooling requires higher investment but provides greater long-term value due to enhanced thermal efficiency and extended battery life.

How to Select the Right Cooling System for Your Project

When choosing between air and liquid cooling, consider:

• Battery capacity and density

• Ambient temperature

• Installation environment

• Maintenance resources

Dagong ESS provides customized design and technical support to match the right cooling solution for each project.

How Long Does a Cooling System Last?
