[0003] In order to achieve higher energy storage efficiency, energy storage cabinets are mostly assembled from battery modules composed of battery cells. The heat dissipation efficiency of battery modules is low, and the battery cells are closely connected. During the charging and discharging process, the battery module will release heat.
