A battery pack, and more particularly, to a battery pack in which a label wrapping a battery cell coupled to a PCM has a thin shape, which does not have an overlapping portion.

Battery pack

A battery pack and a method for manufacturing the same, and more particularly, to a battery pack includes a top cap having a hook protrusion for protecting a PCB connected to a pouch-type battery cell and a method for manufacturing the same.

Battery pack and manufacturing method therefor

A battery pack including: a battery cell provided with electrode terminals formed on one surface thereof and including a sealing surplus portion; a release cover having a label portion attached onto the one surface of the battery cell and displaying information; and a protection circuit module assembly connected to the battery cell through the electrode terminals, wherein the protection circuit module assembly may include: a protection circuit substrate electrically connected to the electrode terminals; an external input/output terminal formed on the protection circuit substrate; and an insulation member positioned between the protection circuit substrate and the battery cell, and wherein the release cover may be formed to enclose the protection circuit module assembly seated on the sealing surplus portion.

Battery pack including release cover

Disclosed herein is a method of manufacturing a battery pack including a battery cell having an electrode assembly received in a battery case, made of a laminate sheet including a resin layer and a metal layer, together with an electrolytic solution. An upper case, a PCB, and a battery cell are simultaneously coupled to each other through a hot-melt process without using additional members, such as double-sided adhesive tape and a PCM case. In particular, a label can be removed from an embedded type battery pack. Consequently, it is possible to improve manufacturing efficiency and reduce manufacturing cost due to the reduction in the number of parts.

Method of manufacturing embedded type battery pack using hot-melt fixing structure and battery pack manufactured using the same

The present invention relates to a manufacturing method of a battery pack including plate-shaped battery cells arranged on a plane so that electrode terminals thereof face each other, including: (a) a process of electrically connecting electrode terminals of battery cells to an electrode terminal connecting portion of a protection circuit board (PCB); (b) a process of mounting the battery cells connected to the PCB in a mold provided with two or more injection holes for a thermoplastic resin; (c) a process of injecting a thermoplastic resin through the injection holes to form a molding frame made of thermoplastic resin on an outer periphery of the PCB and the battery cells; and (d) a process of solidifying the molding frame.

Method and apparatus for manufacturing battery pack having fixing structure made from thermoplastic resin

Disclosed herein is a method of manufacturing a battery pack including a battery cell having an electrode assembly received in a battery case, made of a laminate sheet including a resin layer and a metal layer, together with an electrolytic solution.
