Introduction
LiFePO₄ energy storage batteries are sensitive to temperature fluctuations during long-distance transportation. Whether shipped by sea, air, or land, maintaining a stable temperature environment is essential to prevent degradation, swelling, or safety risks. This article explains recommended temperature ranges and key safety precautions.
1. Recommended Temperature During Transportation
To ensure battery health and prevent performance loss:
| Stage | Recommended Temperature |
|---|---|
| Long-distance shipping | -20°C to 45°C |
| Warehouse storage | 0°C to 30°C |
| Temporary handling at port | 0°C to 35°C |
| High-temperature climate shipping | Avoid > 55°C inside container |
High temperatures accelerate aging of internal components, while low temperatures reduce discharge stability.
2. Risks of Extreme Temperature Exposure
High Temperature Risks (> 55°C)
- Electrolyte decomposition
- Gas generation inside cells
- SEI layer damage
- Shortened cycle life
- Reduced charge acceptance
Low Temperature Risks (< -20°C)
- Lithium plating during charging
- Increased internal resistance
- Possible condensation inside packaging
- Slow discharge reaction
3. How to Maintain Safe Temperature in Shipping Containers
Freight forwarders often use:
✔ Ventilated containers
✔ Reflective insulation materials
✔ Temperature monitoring stickers
✔ Thermal blankets for extreme weather routes
✔ Avoiding direct sunlight at ports
✔ Proper stacking to prevent heat accumulation
4. Special Considerations for Large Energy Storage Cabinets
If shipping rack-mounted or cabinet-type LiFePO₄ solutions:
- Lock the BMS in “transportation mode”
- Disconnect external breakers
- Do not ship with more than 30% SOC
- Ensure internal modules are secured
- Keep vents open to reduce heat buildup
Conclusion
Controlling temperature during transportation is crucial for maintaining LiFePO₄ battery safety and performance. Dealers and logistics teams should always monitor climate conditions and choose temperature-appropriate shipping solutions.
