The present invention relates to a medium-large battery module cartridge having a plurality of plate members forming a multi-layer structure, and more particularly, the medium-large battery module is equipped with plate-shaped battery cells are formed in which the positive electrode terminal and the negative electrode terminal facing in the vertical direction The cartridge constituting the present invention relates to a cartridge comprising a lower plate member, at least one intermediate plate member, and an upper plate member including a specific bending structure and a battery cell accommodating part, and a medium to large battery module including the same.

BACKGROUND ART [0002] In recent years, rechargeable secondary batteries have been widely used as energy sources for wireless mobile devices. Secondary batteries are also attracting attention as a power source for electric vehicles (EVs) and hybrid electric vehicles (HEVs), which are proposed as a way to solve air pollution in conventional gasoline and diesel vehicles that use fossil fuels. .

One or two or four battery cells are used for small mobile devices, whereas medium and large battery modules, which are electrically connected to a plurality of battery cells, are used in medium and large devices such as automobiles due to the necessity of high output capacity.

Since the medium-large battery module is preferably manufactured in a small size and weight, the rectangular battery, the pouch-type battery, etc., which can be charged with high integration and have a small weight to capacity, are mainly used as battery cells of the medium-large battery module. In particular, a pouch-type battery using an aluminum laminate sheet or the like as an exterior member has attracted much attention in recent years due to the advantages of low weight and low manufacturing cost.

1 is a perspective view schematically showing a typical representative pouch-type battery. The pouch type battery 70 of FIG. 1 has a structure in which two electrode leads 10 and 20 protrude from each other to protrude from an upper end and a lower end of the battery main body 30. Exterior member 40 is composed of two upper and lower units, both side surfaces (40a) and the upper and lower ends (40b) which are mutually contacting portions with the electrode assembly (not shown) mounted on the receiving portion formed on the inner surface thereof, The battery 70 is made by attaching 40c). The exterior member 40 is made of a laminate structure of a resin layer / metal foil layer / resin layer, and can be attached by mutually fusion bonding the resin layer by applying heat and pressure to both side surfaces 40a and upper and lower ends 40b and 40c which are in contact with each other. In some cases, the adhesive may be attached using an adhesive. Since both side surfaces 40a are in direct contact with the same resin layer of the upper and lower exterior members 40, uniform sealing is possible by melting. On the other hand, since the electrode leads 10 and 20 protrude from the upper end portion 40b and the lower end portion 40c, the sealing properties are improved in consideration of the thickness of the electrode leads 10 and 20 and the heterogeneity with the material of the exterior member 40. Heat-sealed in the state of interposing the film-like sealing member 60 between the electrode leads 10, 20 so as to be able to.

However, since the mechanical rigidity of the exterior member 40 itself is not excellent, in order to manufacture a battery module having a stable structure, battery cells are generally manufactured by mounting battery cells (unit cells) in a pack case such as a cartridge. Doing. However, since a mounting space is generally limited to a device or a vehicle on which a medium / large battery module is mounted, when the size of the battery module is increased due to the use of a pack case such as a cartridge, there is a problem of low space utilization. In addition, the low mechanical stiffness of the battery cell results in repeated expansion and contraction of the battery cell during charging and discharging, thereby causing a case where the heat fusion sites are separated.

In order to secure the safety of the pouch-type battery cell as described above and to increase the space utilization of the battery module, a technique for a structure for laminating a specific portion of the case in which the battery cells are stored by bending is known.

For example, Japanese Patent Application Laid-Open No. 2005-123127 discloses a technology related to a battery pack including a frame in which a plurality of battery cells can be accommodated, and a partition part between the battery cells being laminated by bending. In Japanese Patent Application Laid-Open No. 1980-122372, there is provided a frame in which a plurality of battery cells can be accommodated, and a hinge structure is connected between each of the frames, and a technique of folding and stacking in a zigzag form along the hinge structure is provided. Is disclosed.

The above technologies suggest a battery pack structure that is stacked along a bent portion by using a case of a bendable structure. However, when a plurality of battery cells are mounted to implement a battery module having a high output and a large capacity, the battery pack may be excessively bent. Therefore, there is a risk that the bent portion is damaged during the assembly process or the electrical connection is cut off due to external impact, etc., when the battery cells are forcibly stacked, excessive load is applied to damage the battery cells.

In addition, Japanese Patent Application Laid-Open No. 2006-185733 discloses a technique for an assembled battery having a structure in which positive electrode tabs of a plurality of cells are arranged so as to overlap with negative electrode tabs of adjacent cells, and then bent and stacked in a connection direction. . However, the above technique may be damaged due to external force applied in the process of bending the electrode terminal, or the connection with the internal electrode assembly may be broken, and a plurality of insulating members, guide members, etc. may be interposed between the bent electrode terminals. Since the members must be inserted individually, the assembly process is not easy and there is a limitation in the application to the mass production process.

On the other hand, since a battery module is a structure in which a plurality of battery cells are combined, when some battery cells are overvoltage, overcurrent, and overheating, safety and operation efficiency of the battery module are greatly detrimental, so a means for detecting them is necessary. Therefore, by connecting a voltage sensor, a temperature sensor, and the like to the battery cells to check and control the operation state in real time or at regular intervals, the installation or connection of such a detection means makes the assembly process of the battery module very complicated and for this purpose. There is also a risk of short circuits due to the large number of wires.

Apart from this, when constructing a medium-large battery module using a plurality of battery cells or a medium-large battery module using a plurality of unit modules consisting of a predetermined unit of battery cells, for the mechanical fastening and electrical connection of the Since many parts are needed, the process of assembling these members is very complicated. Moreover, space is required for joining, welding, soldering, etc. a plurality of members for mechanical fastening and electrical connection, thereby increasing the size of the entire system. This increase in size is not desirable in view of the foregoing, and there is a high need for a battery module having a more compact and excellent structural stability.
