Liquid-Cooled Containerized Energy Storage System Design Plan

This document presents a comprehensive design plan for a liquid-cooled containerized energy storage system with a capacity of 100MW/400MWh. The system utilizes 120 units of 3.35MWh liquid-cooled containers, each comprising 9 parallel battery clusters using 280Ah Lithium Iron Phosphate cells. The design adheres to general principles including suitability for inland areas below 3000m altitude, containerized storage, and integration of temperature control, liquid cooling, and fire protection systems. Redundancy is incorporated for electrical components and key equipment. The battery prefabricated cabins feature double-sided doors for safety and maintenance. The system is designed for grid connection, complying with relevant standards such as DL/T, GB/T, IEC, and NB/T. The document covers system overview, overall design including DC combiner cabinets, internal power supply, fire protection, temperature control, and video surveillance. It also addresses transportation, operation, maintenance, and after-sales support. The total DC side battery capacity is 402.55MWh, ensuring reliable and efficient energy storage for grid integration.
