Disclosed is a clamping member and a battery module using the same. The clamping member includes a pair of pressing units configured to respectively press an upper plate and a lower plate of a battery assembly in which a plurality of batteries is stacked, so that a stacking structure of the battery assembly is fixed, and a support unit configured to support the pair of pressing units so that the upper plate and the lower plate of the battery assembly are pressed by the pair of pressing units, wherein at least one of the pair of pressing units includes a snap-fitting portion coupled to the upper plate or the lower plate by means of snap-fitting, and a screwing portion coupled to the upper plate or the lower plate coupled to the snap-fitting portion, by means of screwing, thereby fixing the battery stacking structure with excellent space efficiency, ensuring easy assembling of the battery module and improving durability of the battery module.

Clamping member and battery module using the same

Disclosed are a clamping device and a battery module comprising the same, the clamping device being suitable for reducing the number of screw coupling portions of long bolts at a lower plate, a battery stack, and an upper plate, and for securing, in a balanced manner, the battery stack, the lower plate and the upper plate by means of the long bolts. The clamping device according to the present invention comprises: a support; and pressing parts respectively protruded from one end and the other end of the support, wherein the support and the pressing parts define a bent part along the central portion of the outer circumference while forming a band shape, and the pressing parts include locking holes which intersect with the bent portion.

Clamping device, and battery module comprising same

Disclosed is a heat sink having improved space utilization and a battery module including the same. The heat sink for cooling a cell assembly including at least one unit cell comprises a first heat sink coupled to one side of the cell assembly and having a first cooling channel through which a coolant passes, and a second heat sink coupled to the other side of the cell assembly and having a second cooling channel through which the coolant passes. Since heat sinks are coupled to both sides of a cell assembly, a Z-axial space of a battery pack may be ensured without increasing the height of the battery pack.

Heat sink and battery module including the same

Disclosed is a battery pack, which includes a battery module including at least one battery cell and having at least one insert hole at a bottom thereof, and a pack case having an accommodation space for accommodating the battery module and having at least one fixing protrusion which is fitted into the at least one insert hole.

Battery pack and vehicle including battery pack

The present disclosure discloses a battery pack suitable for preventing simultaneous separation of both ends of a handle unit from an upper case during transportation of a lower case and the upper case that are laminated sequentially. The battery pack according to the present disclosure includes the lower case and the upper case stacked sequentially to encase a battery module, wherein the upper case includes a housing and a handle unit relatively rotated with respect to the housing to be seated on the housing, and the handle unit has shaft hooks that are penetrated by the rotation supporting shafts of the housing and that are each rotary-coupled to each of the rotation supporting shafts in different angles.

Battery pack

Disclosed is a battery module. The battery module includes: a battery cell stack in which a plurality of battery cells are stacked; a plurality of end plates at least partially surrounding the battery cell stack; and a support member coupled to the plurality of end plates and supporting the plurality of end plates.

Battery module, and battery pack comprising same

The present disclosure discloses a pack case suitable for preventing vibration or deviation of a battery module on a case during an assembly operation, and a battery pack including the same. The pack case according to the present disclosure includes an align unit and a bus bar disposed at an edge on an inner circumferential surface, and a main case having a connection terminal contacting the bus bar on an outer circumferential surface, and the align unit and the bus bar contact a battery module at a periphery of the battery module seated on the inner circumferential surface of the main case.

Pack case and battery pack comprising same

The present disclosure discloses a battery pack that realizes miniaturization and weight reduction by minimizing the number of components of the structure, and that is suitable for pursuing dispersion of external force and structural rigidity using the shape of the structure. The battery pack according to the present disclosure is characterized to include a lower case including both inclined side walls and fixating members facing each other at the both side walls, a battery cartridge disposed between the fixating members in the lower case, and an upper case covering the lower case and the battery cartridge, wherein the battery cartridge contacts the both side walls and the fixating members in the lower case.
