By submerging batteries in a dielectric liquid coolant, this innovative technology prevents fires, enhances system efficiency, and ensures long-term safety and reliability across diverse applications. The system comprises: the liquid cooling unit is connected with the liquid inlet main pipeline and the liquid outlet main pipeline and is used for conveying and recycling coolant. Immersion cooling is revolutionizing battery energy storage systems (BESS) by addressing the root cause of thermal runaway—excessive heat at the cell level. This rapid change and high growth rate has introduced new risks across the supply chain, such as manufacturing defects and complex subsystems with additional points of failure, which can lead to uncontrolled thermal runaway (a duct. The HJ-G215-418L industrial and commercial energy storage system from Huijue Group adopts an integrated design concept, with integrated batteries in the cabinet, battery management system, BMS energy management system, EMS, modular converter PCS and fire protection system. It reduces energy costs. OASIS L241 supports external hybrid inverter, DC coupling access to photovoltaic, integrated system design, one-stop service, high system integration, flexible layout of the scheme, can reduce light abandon-ment, improve the utilization rate of photovoltaic power generation.
