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.

Abstract: The present disclosure relates to a battery pack and an electric system. The battery pack includes: a battery module including a plurality of battery cells arranged in a thickness direction of each of the plurality of battery cells; a limit member abutting against an end of the battery module located in the thickness direction of the battery cell, the limit member having a first recess extending in the thickness direction of the battery cell; and a first binding strip surrounding the battery module and sleeved around the limit member in a height direction of each of the plurality of battery cells. The first binding strip is engaged in the first recess.

Abstract: An energy-storage device, an electricity-consumption system, and an energy-storage system are provided in the disclosure. The energy-storage device includes multiple energy-storage units, an isolation plate, a first thermal insulator, and a second thermal insulator. The multiple energy-storage units are sequentially arranged in a first direction. Each of the multiple energy-storage units includes an explosion-proof valve. The isolation plate is located at one side of each of the multiple energy-storage units where the explosion-proof valve is located, extends in the first direction, and defines multiple vents arranged at intervals in the first direction. Each of the multiple vents is at least partially aligned with a corresponding explosion-proof valve, and different explosion-proof valves are aligned with different vents. The first thermal insulator and the second thermal insulator are both located at one side of the isolation plate away from the multiple energy-storage units.

Abstract: A battery box includes end plates, side plates, and welding members. One of the end plates is provided between two adjacent side plates. The end plates and the side plates are connected to one another to enclose a cavity of the battery box. The welding members are formed by bending an end portion of a side plate or an end portion of an end plate multiple times. The end portion of the side plate and the end portion of the end plate are configured to implement the connection of the side plates and the end plates to one another to enclose the cavity of the battery box. The welding members are configured to be welded to a corresponding side plate.

Abstract: The present application discloses an air purifier, including: a first body including a first housing; and a second body detachably connected to the first body and including a second housing, where buckles are arranged on the first housing, and snap-fit members are arranged on the second housing; the number of the buckles is greater than the number of the snap-fit members; and the first body in butt joint is enabled to rotate relative to the second body, so that the buckles can be hooked with the snap-fit members or separated from the snap-fit members. In the air purifier, a larger number of buckles are hooked with a smaller number of snap-fit members, so that disassembly and assembly operations can be simplified. Because the first body and the second body are detachable, the second body can be operated independently when the filter screen is detached.

Abstract: The present application is provided with a battery box and a battery module. The battery box includes a plurality of end plates; a plurality of side plates, where one end plate is provided between adjacent side plates, and the end plates and the side plates enclose and form a cavity of the battery box. A plurality of welding members are formed by bending an end portion of each of the side plates and/or each of the end plates for enclosure for multiple times. Each of the welding members is configured to weld to a corresponding end plate or side plate.
