Abstract
An energy storage device includes a box body, a battery module, and a heat insulation plate. The battery module includes multiple battery cells and a separator arranged on the multiple battery cells. The separator has multiple pressure relief holes arranged corresponding to explosion-proof valves of the multiple battery cells, respectively. The heat insulation plate is arranged between a top of the box body and the battery module. The heat insulation plate has multiple thinned regions. The separator includes multiple protrusions. The multiple protrusions are arranged between the multiple pressure relief holes and the multiple thinned regions, respectively. Each of the multiple protrusions is hollowed to form a communication end and a hollowed-out end. The communication end is in communication with a corresponding one of the multiple pressure relief holes. The hollowed-out end is configured to support a corresponding one of the multiple thinned regions and constructed to be hollowed.
