Working Temperature of LiFePO₄ Battery and Its Application in Energy Storage Systems

What is the Working Temperature of LiFePO₄ Battery?

LiFePO₄ (Lithium Iron Phosphate) batteries are known for their excellent thermal stability and safety compared with other lithium-ion chemistries. The typical working temperature range of LiFePO₄ batteries is:

• Charging temperature: 0°C to 55°C

• Discharging temperature: -20°C to 60°C

These characteristics make LiFePO₄ an ideal choice for energy storage systems (ESS) operating in diverse environments — from residential homes to large-scale industrial facilities.

Temperature Challenges in Energy Storage Systems

Temperature significantly affects the capacity, internal resistance, and lifespan of lithium batteries.

• At low temperatures, the electrochemical reaction rate decreases, reducing available capacity.

• At high temperatures, the electrolyte may degrade faster, shortening the cycle life.

To overcome these challenges, professional ESS manufacturers have developed thermal management systems, including air cooling and liquid cooling, to ensure safe and efficient operation.

Applications of LiFePO₄ ESS Under Different Climates

• Hot Regions (Africa, Middle East, Southeast Asia): Air-cooled ESS with high-efficiency ventilation systems

• Cold Regions (Europe, Canada, Northern China): Liquid-cooled ESS ensuring optimal thermal performance

• Commercial and Industrial Sites: Temperature-stable operation for load shifting and peak shaving

• Renewable Energy Projects: Reliable battery performance under outdoor environmental variations

Price of Temperature-Optimized ESS

The cost of temperature-controlled LiFePO₄ ESS depends on several factors including system capacity, cooling method, and configuration.
Pricing is generally quoted under EXW, FOB, or CIF terms, depending on project location and logistics.
For the most accurate quotation, it is recommended to consult the supplier directly.

How to Select the Right ESS for Your Temperature Conditions?

• Check the ambient temperature range of your project site

• Choose air-cooled ESS for moderate climates and liquid-cooled ESS for extreme conditions

• Evaluate installation environment (indoor/outdoor) and ventilation conditions

• Consider future scalability and maintenance accessibility

How Long Does a LiFePO₄ ESS Last?

Dagong ESS systems are designed for over 8000 cycles at 70% SOH, with an estimated service life of 15 years or more under proper thermal management.
