Air-Cooled vs. Liquid-Cooled LFP ESS: Which is Right for Your Project?

What is LFP ESS Cooling Technology?

Lithium Iron Phosphate (LFP) batteries are widely used in energy storage systems (ESS) because of their safety, stability, and long lifespan. However, as system capacities increase—from residential 5kWh units to large-scale containerized 5MWh projects—thermal management becomes critical.

Two major cooling methods dominate the market: air-cooled and liquid-cooled systems. Each has its advantages depending on the application, cost, and operating environment.

Types of LFP ESS Cooling Systems

Air-Cooled ESS
Uses fans and airflow to maintain battery temperature.

• Common in small to medium-sized systems.

• Simpler design and easier maintenance.

• Cost-effective for standard applications.

• Example: Dagong ESS 100kWh–241kWh air-cooled cabinets.

Liquid-Cooled ESS
Uses coolant circulation for precise heat management.

• Best for high-capacity and industrial systems.

• Maintains temperature uniformity across cells.

• Higher efficiency under heavy loads.

• Example: Dagong ESS 215kWh and 372kWh liquid-cooled systems.

Features of Air-Cooled vs. Liquid-Cooled LFP ESS

Air-Cooled Systems

• Lower initial cost

• Easier installation and maintenance

• Suitable for mild climates and moderate loads

• Compact design for residential and commercial use

Liquid-Cooled Systems

• Precise temperature control

• Better suited for hot climates or high-power cycles

• Extended battery lifespan under heavy-duty use

• Ideal for large industrial or utility-scale storage

Applications of Air-Cooled and Liquid-Cooled ESS

• Residential Energy Storage (5kWh–80kWh)
  Typically uses air-cooled wall-mounted or stackable systems.

• Commercial Buildings (100kWh–241kWh)
  Air-cooled cabinets handle peak shaving and backup power efficiently.

• Industrial Applications (215kWh–372kWh)
  Liquid-cooled systems manage high loads with greater stability.

• Utility-Scale Projects (3.35MWh–5MWh)
  Containerized liquid-cooled systems ensure safe, stable operation under continuous cycling.

For example, Dagong ESS 3.35MWh liquid-cooled container is commonly applied in solar farms, while 5MWh air-cooled containers support commercial parks and microgrids.

Price of Air-Cooled vs. Liquid-Cooled ESS

The cost of LFP energy storage systems for renewable energy integration depends on several factors, including:

• System capacity

• Cooling method (air vs. liquid)

• Installation environment

• Auxiliary equipment and control software

Pricing is usually quoted under international trade terms such as EXW, FOB, or CIF, depending on project location and logistics preferences.
For a tailored quotation based on your specific project needs, it is best to consult directly with the supplier.

How to Select the Right Cooling System?

• For Residential & Small Businesses: Air-cooled systems (5kWh–100kWh) are typically sufficient.

• For Medium Commercial Use: Air-cooled cabinets up to 241kWh provide cost-effective peak shaving.

• For Industrial & Utility Projects: Liquid-cooled systems (215kWh–372kWh, 3.35MWh containers) ensure better performance.

• Climate Consideration: Hot climates or high cycling conditions favor liquid cooling.

• Budget & Maintenance: Air cooling offers simplicity and lower costs, liquid cooling offers efficiency and long-term stability.

How Long Do These Systems Last?

• Air-Cooled ESS: Typically 8,000 cycles and 10–12 years under standard usage.

• Liquid-Cooled ESS: Designed for 15+ years of operation, especially in heavy-duty applications.

Both systems benefit from LFP chemistry’s inherent stability, ensuring safety throughout their lifecycle.
