Thermal Problems in Energy Storage Systems – Case Study

The article presents the results of analyses of heat flow processes within the design of a containerized energy storage system, which allows for easy relocation. Using applicable standards, a thermal design of the storage system was developed. However, numerical calculations revealed the limitations of this approach and highlighted the need for an individualized approach to such projects. The discussion addresses issues related to the optimization of internal design as well as the cooling and heating systems employed. The article is supplemented with results from original investigations of the capacitance of lithium-ion batteries and supercapacitors.
