Containerized Battery Energy Storage System (BESS)

This containerized battery energy storage system (BESS) system is a highly integrated energy storage solution based on lithium iron phosphate (LFP) technology. It utilizes 280Ah / 314Ah LFP battery cells. The air-cooled battery container capacity ranges from 1.5 to 3.35 MWh per unit, while the liquid-cooled version ranges from 2 to 5 MWh per unit. The energy storage system is equipped with an integrated PCS (power conversion system) and step-up transformer unit, meeting project requirements from 0.25C to 1C.

• High-Level Integration: The energy storage system utilizes an all-in-one integrated design, incorporating batteries, battery management system (BMS), thermal management, low-voltage power distribution, fire suppression, access control, and comprehensive monitoring. This streamlined architecture significantly reduces on-site installation time and integration costs.
• Advanced Safety & Reliability: A triple-layer BMS architecture enables real-time monitoring and management across the entire system. The integration of a fire-suppression linked shutoff mechanism and robust grounding design ensures the sustained safe and stable operation of the battery arrays.
• Extreme Environmental Resilience: With an IP55-rated enclosure, the system features a ruggedized waterproof, dustproof, fire-resistant, and anti-corrosion design. It is engineered to withstand extreme wind, snow, and seismic loads, making it ideal for harsh environments, including sandstorms and wide-range temperature fluctuations.
