Abstract: A battery pack includes a plurality of cartridges that are stackable in a vertical direction in which each cartridge of the plurality of cartridges extends in a longitudinal direction perpendicular to the vertical direction, and a plurality of battery cells in which each battery cell is disposed in a cartridge of the plurality of cartridges. Each cartridge of the plurality of cartridges includes a battery cell contact body that is configured to contact a battery cell of the plurality of battery cells and support the battery cell, and at least one duct that is configured to transmit heat from the battery cell contact body to air by passing air through the at least one duct. Each duct of the plurality of cartridges is configured to communicate air with another duct of an adjacent cartridge.

Abstract: A battery pack includes a plurality of battery modules that are stackable in a stacking direction, each of the plurality of battery modules extending in a longitudinal direction perpendicular to the stacking direction. Each of the plurality of battery modules includes a battery cell and a cartridge configured to receive the battery cell. The cartridge includes a seat part configured to seat the battery cell, and a heat dissipation part made of a first type of material different from a second type of material of the seat part, the heat dissipation part being configured to absorb heat generated from the battery cell.

Abstract: A battery pack may include a battery cell with a cell lead; a bus bar bonded to the cell lead and having a terminal pin; a connection board having the bus bar mounted thereon; and a printed circuit board (PCB). The PCB may have a terminal clip selectively connected to and disconnected from the terminal pin of the bus bar. The battery pack may also include a PCB housing defining a PCB accommodation space accommodating the PCB. The battery pack may further include a locking part that, in a first locking state, locks the PCB housing to the connection board at a first position where the terminal pin of the bus bar does not elastically deform the terminal clip of the PCB; and in a second locking state, lock the PCB housing to the connection board at a second position where the terminal pin elastically deforms the terminal clip.
