6.25MWh Liquid-cooled Energy Storage Battery Compartment Spec

This document specifies a 6.25MWh liquid-cooled energy storage battery compartment using 587Ah lithium iron phosphate cells. The system is designed for generation, grid, and user-side applications, offering high safety, ultra-long cycle life, and superior charge/discharge performance. It features a three-level BMS monitoring voltage, temperature, and current with overcharge/over-discharge protection. The compartment includes a perfluorohexanone fire extinguishing system, water fire protection, smoke detectors, and explosion-proof ventilation. The liquid cooling system uses horizontal variable frequency units with modular pipelines to maintain temperature uniformity (max 5°C difference). The 20-foot high cube enclosure (IP55) houses eight battery racks, four high voltage boxes, and auxiliary systems. Communication interfaces include CAN, RS485, and Ethernet. The document covers system parameters, battery modules, thermal management, fire protection, installation, and packaging requirements.
