Abstract: A battery pack includes: a plurality of battery cells; a plurality of frames each between two adjacent battery cells among the battery cells in a direction, the frames coupled to and facing each other; and a wiring substrate mounted on the frames and configured to collect status information of the battery cells from the battery cells, and each of the frames includes a latching protrusion and a tensioner which protrude therefrom and press against an upper surface and a lower surface of the wiring substrate, respectively. The battery pack has an improved structure in which the position of the wiring substrate for obtaining and collecting status information of the plurality of battery cells may be stably fixed.

Abstract: A battery pack includes a series of battery cells, a series of bus bars electrically connecting the series of battery cells, and a terminal member. The terminal member includes a first metal layer extending from an internal connection position connected to at least one of the series of bus bars to an external connection position for supplying output power of the battery pack. The terminal member also includes a second metal layer covering the first metal layer at the external connection position. The second metal layer includes a second metal different from a first metal of the first metal layer. Therefore, the battery pack has an improved structure for stable and low-resistance connection.

Abstract: Provided is a battery pack. The battery pack includes: a battery cell including a cell vent; frames arranged together with the battery cell in a direction and coupled together to face each other with the battery cell therebetween, the frames including guide ribs surrounding the cell vent; and a top cover arranged above the frames to cover the frames and including a protruding barrier wall surrounding the guide ribs.
According to the present disclosure, the battery pack has an improved vent structure to rapidly discharge gas generated in an abnormal battery cell to the outside of the battery pack.
