A battery module according to an embodiment of the present disclosure may include: a battery cell stack having a plurality of battery cells stacked in a stacking direction; a module frame accommodating the battery cell stack; a thermally conductive resin layer located between a lower surface of the module frame and the battery cell stack; and a first adhesive layer located between adjacent battery cells, among the plurality of battery cells, and a liquid injection hole for injecting the thermally conductive resin layer may be formed on the lower surface of the module frame and the first adhesive layer is formed adjacent to the thermally conductive resin layer.

Battery module and battery pack including the same

A battery module includes a battery cell stack in which a plurality of battery cells are stacked, and a frame member accommodating the battery cell stack and having an upper surface and a lower surface corresponding to each other, wherein an injection hole for injecting a thermally conductive resin is formed in the lower surface of the frame member, and wherein an insertion hole through which a protrusion of a supporting jig is configured to be passed is formed in the upper surface of the frame member.

Battery module, manufacturing method thereof and battery pack including battery module

A battery pack includes: a battery module formed by stacking battery cells; an upper frame positioned on an upper surface of the battery module; a first side frame positioned on a first side surface of the battery module; and a second side frame positioned on a second side surface of the battery module facing the first side frame. The upper frame includes one or more first hinge parts positioned at one end of the upper frame. The first side frame includes one or more first poles positioned at an upper edge of the first side frame and fastened to the first hinge part. A first opening into which the first pole is inserted is formed in the first hinge part, and the first opening is formed obliquely so as to face between a direction perpendicular to the upper frame and a direction parallel to the upper frame.

Battery pack including upper frame having obliquely opened hinge fastened to side frame, and device including the same

A battery module includes a cell assembly including at least one battery cell, a module case accommodating the cell assembly, an upper frame positioned on one surface of the cell assembly in the module case to at least partially cover the cell assembly, a flexible printed circuit board configured to be mounted longitudinally on the upper frame to sense the battery cell, and a protective cover in which a main cover portion parallel to a main surface of the upper frame is mounted on the upper frame so as to cover the flexible printed circuit board in the module case.
