Abstract: The emergence of containerized energy storage technology is accompanied by the growth of the installed capacity of new energy generation equipment (wind power, photovoltaic, etc.), whose energy grid consumption and lack of peaking capacity came into being while it's also an important support for future grid development. The container energy storage mainly consists of battery compartment and booster compartment, where the battery compartment plays a decisive role in the safety and reliability of the whole energy storage system operation. This paper mainly describes the overall design and theoretical thermal calculation of the battery compartment of the energy storage system, and carries out static load calibration and seismic systematic research by using ANSYS analysis software, which verifies the reliability of the whole system in the national standard 7- degree seismic intensity, and the results of the research provide a safe basis for the actual operation of the project.
