The present disclosure relates to an energy storage cabin. The energy storage cabin includes a cabin body and a cabin door. The cabin body has an opening and a first accommodation space. The cabin door is disposed at the opening of the cabin body in an openable and closable manner. The cabin door includes an inner door panel, an outer door panel, and a connecting member. The inner door panel is located at an inner side of the outer door panel in a stacking manner. A thermal insulation layer is provided between the inner door panel and the outer door panel. The connecting member penetrates the inner door panel to connect the inner door panel with the outer door panel. A heat insulation pad is sandwiched between the inner door panel and the outer door panel at a position where the connecting member penetrates the inner door panel.
