Abstract: An energy storage device is provided in the disclosure. The energy storage device includes a case, multiple battery modules, at least one cooling assembly, and at least one heat insulation support. The multiple battery modules are accommodated in the case. The at least one cooling assembly is arranged between the multiple battery modules. The at least one heat insulation support is fixedly connected to the case. The at least one heat insulation support each defines a fixing groove configured to fix one of the at least one cooling assembly.

Abstract: The present utility model discloses a battery pack and an energy storage device. The battery pack includes at least two battery modules and at least one cooling assembly. Each battery module includes a support having a splicing portion and a plurality of battery cells mounted in the support, and two adjacent battery modules are connected to each other by two splicing portions. The at least one cooling assembly is sandwiched between the two adjacent battery modules and is in contact with the battery cells located on opposite sides of the at least one cooling assembly. According to the battery pack, the battery modules and the cooling assembly can be spliced as needed, then battery packs with different numbers of battery cells can be conveniently achieved, and the cost of the battery pack is reduced.

Abstract: Provided are a battery module and an energy storage device. The battery module includes cylindrical cells arranged in at least two rows and a liquid-cooled assembly including at least one liquid-cooled unit each including a liquid-cooled tube and a cooling fin; the liquid-cooled tube includes a first tube arranged at an upper end of the cooling fin, a second tube, and a third tube arranged at a lower end of the cooling fin; the second tube connects one end of the first tube with one end of the third tube; the cooling fin is arranged between two adjacent rows and is connected to circumferential side surfaces of cells in the two adjacent rows; the first tube and the third tube each have an opening defined in another end thereof facing away from the second tube.

Abstract: Provided are a cover assembly for a battery and a battery. The cover assembly for the battery includes an elastic cover, an insulating cover, a frame support member and a terminal column assembly. The insulation cover is embedded in one end of the elastic cover. The frame support member has a greater hardness than the elastic cover and the insulating cover. The frame support member is embedded in the other end of the elastic cover. The elastic cover has an encapsulation portion disposed on an outside, in a radical direction, of the insulating cover and the frame support member. The encapsulation portion is in a cylindrical shape and configured to abut against an inner surface of a housing of the battery. The terminal assembly includes a terminal penetrating the insulating cover and the elastic cover.

Abstract: Provided are a top cover assembly of a cell, a cell, and a power battery. The top cover assembly includes an insulation cover plate, a metallic support plate, a terminal assembly, and an elastic seal. The metallic support plate and the insulation cover plate are stacked in a thickness direction. The terminal assembly passes through the insulation cover plate and the metallic support plate in the thickness direction to connect the insulation cover plate and the metallic support plate. The elastic seal surrounds a peripheral outside of the metallic support plate and the insulation cover plate. The elastic seal has a positioning flange provided on an inner peripheral surface thereof and is configured to be in a sealing fit with a housing of the cell. The positioning flange is sandwiched between the metallic support plate and the insulation cover plate.

Abstract: The present disclosure relates to a fixing frame and a battery pack. The fixing frame comprises a top connecting frame comprising two or more fixing plates spaced apart from each other in a first direction and a connecting component connecting the two adjacent fixing plates, the connecting component comprising a recess portion and an adapter portion, the recess portion being recessed in a second direction and the adapter portion being connected to both sides of the recess portion in the first direction, and the connecting component being connected to the two adjacent fixing plates via the adapter portion; and locking plates provided on the top connecting frame and extending along the second direction, the locking plate comprising in the second direction a first end connected to the top connecting frame and a second end connectable to an external structural member; wherein the first direction intersects the second direction.
