AI Technical Summary
Existing energy storage systems' thermal management methods are insufficient to achieve comprehensive and precise thermal management of battery modules, resulting in poor overall temperature uniformity of battery modules, large temperature differences between cells, and potential safety hazards.
An immersion cooling method is adopted, which cools the battery module from the top and bottom simultaneously. The lower and upper sides of the battery module are cooled by the first and second cooling pipes respectively, forming a comprehensive thermal management system. Heat exchange is carried out by circulating cooling and refrigeration devices using immersion liquid.
It improves the overall temperature uniformity of the battery module, reduces the temperature difference between cells, enhances the safety and stability of the energy storage system, and extends the battery life.
