The invention discloses an
energy storage container which comprises a container body and a top cover
assembly. The box body comprises a first fireproof heat insulation part and a top opening, and the first fireproof heat insulation part at least surrounds the top opening and is arranged at the top of the box body; the top cover
assembly is detachably connected to the top of the box body so as to be capable of moving between a closed position covering the top opening and an open position removed from the box body, the top cover
assembly comprises a top plate and a second fireproof heat insulation part, the
peripheral edge of the top plate is detachably connected to the top of the box body, and the second fireproof heat insulation part is arranged on the top plate. The second fireproof heat insulation part covers the bottom of the top plate, the first fireproof heat insulation part and the second fireproof heat insulation part are flexible, and when the top cover assembly is in the closed position, the first fireproof heat insulation part and the second fireproof heat insulation part are flexible. The first fireproof heat insulation part can abut against the
peripheral edge of the second fireproof heat insulation part in the circumferential direction of the top opening. Therefore, the heat preservation and fireproof performance of the
energy storage container can be improved.
