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

What is discussed is an interconnection member including (a) a main cable made of a flexible flat cable (FFC) including copper wires, (b) terminal parts branched from the main cable and electrically connected to at least one of the copper wires of the main cable, (c) a connecting part formed on one-side end of the main cable, and electrically and mechanically connected to a PCB and (d) at least one temperature sensing part branched from the main cable, wherein the at least one temperature sensing part comprises a first extending part extending from the main cable while sharing at least one copper wire of the copper wires of the main cable and a ceramic thermistor disposed on an end of the first extending part while being electrically connected to the first extending part.

Interconnecting member occupying less space in battery module and battery module comprising same

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.

Battery module including protection cover covering flexible printed circuit board

Provided is an interconnection member including: (a) a main cable made of a flexible flat cable (FFC) including a plurality of copper wires; (b) a plurality of terminal parts branched from the main cable and electrically connected to at least one of the copper wires of the main cable, the plurality of terminal parts being connected to the bus bars to sense voltages of the battery cells; (c) a connecting part formed on one-side end of the main cable, and electrically and mechanically connected to the PCB; and (d) at least one temperature sensing part branched from the main cable, adjacent to the connecting part, while sharing at least one of the copper wires of the main cable.

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

A battery cell assembly in which a plurality of electrically connected battery cells are arranged and first and second outer cover members each having a plate-type structure surrounding an outer surface of the battery cell assembly and coupled to each other by a fastening member in a state in which corners corresponding to each other are in contact with each other. Here, each of the first and second outer cover members includes at least one fastening groove having a slit shape, and the fastening grooves of the first and second outer cover members are perforated at positions corresponding to each other of corners contacting each other, and the first and second outer cover members are coupled to each other in such a manner that both side ends, which face each other, of the fastening member are respectively inserted into the fastening grooves in a clamping manner.
