Disclosed is a battery pack including a battery module assembly including two or more battery modules, each of the battery modules having one or more battery cells arranged adjacent to each other in the state of being mounted in cartridges, a base plate allowing the battery module assembly to be loaded thereon, and a hold-down bracket fixing the battery module assembly to the base plate, wherein each of the cartridges includes a step portion having a lower part protruding outwards, the hold-down bracket includes an upper end portion covering upper surfaces of the step portions of the cartridges, a lower end portion coupled to the base plate, and a middle portion connecting the upper end portion and the lower end portion to each other, and a protrusion structure protruding in a direction toward the base plate is formed on the lower end portion.

Battery pack including hold-down bracket having protrusion structure formed thereon

The present invention provides a battery pack including: a battery module assembly including a plurality of battery cells; a tray assembly having an upper surface on which the battery module assembly is mounted; a cover member having an outer periphery coupled to face an outer periphery of the tray assembly while the battery module assembly is accommodated therein; and a sealing gasket interposed between the mutually facing outer peripheries of the tray assembly and the cover member.

Battery pack comprising gasket compression limiter

The present invention provides a battery pack mounted to a battery pack mounting part of a device for supplying power, including: a base plate including one surface on which two or more battery module assemblies respectively having a plurality of battery cells arranged therein are mounted in a separated state from each other with a predetermined interval therebetween; a cover member mounted on one surface of the base plate while enclosing the battery module assemblies; and a reinforcement supporting member positioned at a separation part between the battery module assemblies while supporting the mounting state of the cover member for the base plate, wherein the battery pack is mounted in a state in which an external circumferential surface of the cover member faces a battery pack mounting part of a device.

Battery pack minimized with mounting space for device

A battery pack has a base plate including one surface on which two or more battery module assemblies respectively having a plurality of battery cells arranged therein are mounted in a separated state from each other with a predetermined interval therebetween. A cover member battery is coupled at one surface of the base plate in a state that the module assemblies are incorporated therein. A reinforcement supporting member is positioned at a separation part between the battery module assemblies while supporting a mounting state of the cover member for the base plate.

Battery pack including reinforcement supporting member

Provided is a battery module including a plurality of cartridges stacked with a battery cell interposed therebetween, wherein each of the cartridges includes: a cooling fin having a plate-shaped structure contacting an outer surface of the battery cell; and a cartridge frame which has a hollow structure and to which an outer peripheral edge of the cooling fin is fixed, wherein, each of guide parts, which is mounted in one side- or the other side-direction of the cartridge frame, is disposed on the outer peripheral edge of the cooling fin so as to fix the cooling fin in position with respect to the cartridge frame, and the cartridges are arranged so that directions in which the guide parts of the cooling fins are mounted with respect to the cartridge frames are opposite to each other in adjacent cartridges.
