Abstract: The container type energy storage system as a new form of engineering, can greatly save time limit for a project, which compared with the traditional way of site construction. Reliable thermal design, is the foundation that the battery system is reliable and safe operation. Based on the finite element analysis software, the different thermal design scheme selection is analyzed, and the reliability of the thermal design is validate, in view of the complex lithium battery energy storage system.

Key words: thermal design, finite element thermal analysis, energy storage system, the lithium battery
