The present invention relates to: a battery module cover member that has a pattern of protrusions protruding in different directions formed thereon, and thus has improved flatness; a battery module case including the cover member; and a battery module including the same. Although manufactured as a thin film, the battery module cover member has excellent mechanical strength and flatness due to the formation of a pattern of protrusions protruding in opposite directions.

Battery module cover member having pattern of protrusions protruding in different directions formed thereon, manufacturing method therefor, and battery module including same

A battery pack is provided including a battery module having a plurality of battery cells or a unit module having the plurality of battery cells; a battery pack frame body including a base plate on which the battery module or the unit module is mounted, and a first side plate and a second side plate connected to the base plate and disposed to face each other; a top frame coupled to an upper portion of the battery pack frame body; and a first end plate and a second end plate electrically connected to electrode terminals of the battery module or the unit module, wherein at least one of the first end plate and the second end plate is configured to include slits.

Battery pack comprising battery pack frame capable of preventing welding defect and pressing jig for preparing the same

A battery pack according to an exemplary embodiment of the present invention includes a plurality of unit modules consecutively disposed in a first direction, a unit cooling member having through-passages while being stacked with the unit modules, and a pressure member to press the unit cooling member. The through-passages of unit cooling members that are adjacent in the first direction are connected to allow a coolant to flow.

Battery pack

A battery pack which includes a plurality of battery modules, each battery module including a plurality of battery cells. Electrode leads extend from the plurality of battery cells; a connection member connects with at least one of the electrode leads; a bus bar electrically connects neighboring battery modules, and one end thereof contacts the connection member. An insulation member covers a contact portion of the connection member and the bus bar; and a flame spread blocking member overlaps the contact portion of the connection member and the bus bar, while being disposed on the insulation member.
