Abstract: 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.

Abstract: 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.
