Introduction

Efficient Thermal Management: Using a bionic capillary-style liquid cooling pipe layout, temperature uniformity is improved by 40% compared to traditional air cooling. Temperature differences inside the container are controlled within ≤5℃, effectively reducing the risk of battery thermal runaway and extending cell life by over 20%.
2. High Safety Protection: Equipped with lithium iron phosphate cells (certified by UN38.3 and UL9540A), combined with pack-level perfluorohexanone spray and cabin-level water fire suppression for dual redundancy, along with combustible gas detection and explosion venting devices, creating a five-level safety protection system.
3. High Density and Flexibility: Single-container rated energy covers 3.44MWh–5MWh, with areal energy density reaching 217kWh/m², a 45% improvement over air-cooled systems; supports multi-container parallel “plug-and-play,” suitable for phased deployment in large-scale energy storage stations and mixed-use scenarios with new and old batteries, reducing lifecycle cost (LCOS) by 10%.
4. Intelligent Operation and Maintenance: Through BMS and cloud platforms, cell-level parameter monitoring is achieved, supporting remote management via Web/APP, combined with AI fault diagnosis algorithms for risk prediction. The modular structure reduces single-module maintenance costs by 30% and shortens delivery cycles to within 40 days.
5. Wide Environmental Adaptability: IP54 protection rating + C5 corrosion-resistant design, supports operation in a wide temperature range of -35℃~60℃, adapts to high altitude (≤4000m), high humidity (0~95% non-condensing), and salt fog environments, meeting the requirements for long-term stable outdoor operation.
