Description

단위모듈들을 포함하는 전지모듈 어셈블리Battery module assembly including unit modules

본 발명은 단위모듈들을 포함하는 전지모듈 어셈블리에 관한 것이다.The present invention relates to a battery module assembly including unit modules.

이차전지는 와이어리스 모바일 기기의 에너지원으로 사용될 뿐만 아니라, 화석 연료를 사용하는 기존의 가솔린 차량, 디젤 차량 등의 대기오염 등을 해결하기 위한 방안으로 제시되고 있는 전기자동차(EV), 하이브리드 전기자동차(HEV) 등의 동력원으로도 사용되고 있다.Secondary batteries are not only used as energy sources for wireless mobile devices, but are also being proposed as solutions for air pollution in conventional gasoline and diesel vehicles that use fossil fuels. It is also used as a power source such as HEV).

따라서, 이차전지를 사용하는 에플리케이션의 종류는 이차전지의 장점으로 인해 매우 다양화되어 가고 있으며, 향후에는 지금보다 많은 분야와 제품들에 이차전지가 적용될 것으로 예상된다.Therefore, the type of applications using the secondary battery is very diversified due to the advantages of the secondary battery, and it is expected that the secondary battery will be applied to many fields and products in the future.

소형 모바일 기기들에는 디바이스 1 대당 하나 또는 두서너 개의 전지셀들이 사용됨에 반하여, 자동차 등과 같은 중대형 디바이스에는 고출력 대용량의 필요성으로 인해, 다수의 전지셀을 전기적으로 연결한 중대형 전지모듈이 사용된다Small mobile devices use one or two or four battery cells per device, whereas medium and large devices such as automobiles use a medium and large battery module electrically connected to a plurality of battery cells due to the need for high output and large capacity.

전지모듈의 크기와 중량은 당해 중대형 디바이스 등의 수용 공간 및 출력 등과 직접적인 관련성이 있으므로, 제조업체들은 가능한 한 소형이면서 경량의 전지모듈을 제조하려고 노력하고 있다. 또한, 전기자전거, 전기자동차 등과 같이 외부로부터 많은 충격, 진동 등을 받는 디바이스들은 전지모듈을 구성하는 소자들간의 전기적 연결상태와 물리적 결합상태가 안정적이어야 하며, 다수의 전지를 사용하여 고출력 및 대용량을 구현하여야 하기 때문에 안전성 측면도 중요시 되고 있다.Since the size and weight of the battery module are directly related to the accommodation space and output of the medium and large devices, manufacturers are trying to manufacture a battery module that is as small and lightweight as possible. In addition, devices that receive a lot of shocks and vibrations from the outside, such as electric bicycles and electric vehicles, should have a stable electrical connection state and physical coupling state between the elements constituting the battery module. Safety aspects are also important because they must be implemented.

중대형 전지모듈은 가능하면 작은 크기와 중량으로 제조되는 것이 바람직하므로, 높은 집적도로 충적될 수 있고 용량 대비 중량이 작은 리튬 이차전지 기반의 각형 전지, 파우치형 전지 등이 중대형 전지모듈의 전지셀로서 주로 사용되고 있다.Since medium and large battery modules are preferably manufactured in a small size and weight, a lithium secondary battery-based square battery and a pouch-type battery, which can be charged with high integration and have a small weight to capacity, are mainly used as battery cells of a medium and large battery module. It is used.

그러나, 상기 리튬 이차전지는, 제조 공정에 의해 비교적 가격이 높고 저온에서의 사용 특성이 상대적으로 떨어지며, 다양한 크기의 제품 적용에 한계로 인해, 근래에는 리튬 이차전지 기반의 원통형 전지도 많이 사용되고 있다. However, the lithium secondary battery has a relatively high price and relatively low use characteristics at low temperatures due to the manufacturing process, and due to limitations in the application of various sizes of products, a lithium secondary battery-based cylindrical battery has also been used in recent years.

원통형 전지는 일반적으로 각형 및 파우치형 전지보다 큰 전기용량을 가지지만, 원통형 전지의 외형적 특성상 적층 구조로의 배열을 유지하는데 많은 어려움이 있어 별도의 고정장치의 사용이 요구된다. 예를 들어, 상기 원통형 전지들을 배열하고 테이프로 고정하거나 플라스틱 코팅하여 배열 구조를 유지하는 방법이 많이 사용되고 있으며, 원통형 전지들간의 결합력을 더욱 높이기 위하여 전지들 사이에 양면 테이프를 부착하기도 한다.Cylindrical batteries generally have a larger capacitance than rectangular and pouch cells, but due to the external characteristics of the cylindrical batteries, there are many difficulties in maintaining the arrangement in a stacked structure, and thus requires the use of a separate fixing device. For example, a method of arranging the cylindrical batteries and fixing them with tape or plastic coating to maintain the arrangement structure is widely used, and double-sided tapes may be attached between the batteries to further increase the bonding force between the cylindrical batteries.

한편, 도 1에는 종래의 전지모듈의 일 예가 모식도가 도시되어 있는 바, 도 1을 참조하면, 종래의 전지모듈(50)은 다수의 원통형 전지들(10)을 포함하는 단위모듈들(30)과 이를 전기적으로 연결하는 버스 바(20)를 포함하고 있으며, 단위모듈(30)은 5행 및 5열의 구조로 이루어져 있고, 열 방향(세로 방향)으로 동일한 전극의 전극단자들이 배열되고, 행 방향(가로 방향)으로 서로 다른 전극단자들이 배열되어 있다. 따라서, 상기 원통형 전지들의 적층 구조의 특성상 외부 케이스에 장착되는 과정에서 높이에 대한 제약으로 인해, 전지모듈과 외부 케이스 사이에 별도의 절연 테이프가 부착되어 있으므로, 공간활용 측면 뿐만 아니라, 제조 공정 과정도 복잡해지는 문제점이 있다.On the other hand, Figure 1 shows a schematic diagram of an example of a conventional battery module, referring to Figure 1, the conventional battery module 50 is a unit module 30 including a plurality of cylindrical batteries (10) And a bus bar 20 for electrically connecting them, the unit module 30 has a structure of 5 rows and 5 columns, and electrode terminals of the same electrode are arranged in a column direction (vertical direction), and in a row direction. Different electrode terminals are arranged in the (horizontal direction). Therefore, due to the limitation on the height in the process of being mounted on the outer case due to the characteristic of the laminated structure of the cylindrical batteries, a separate insulating tape is attached between the battery module and the outer case, not only the space utilization side, but also the manufacturing process There is a problem of becoming complicated.

더욱이, 이 같은 전지모듈을 구성하는 원통형 전지셀의 경우에는, 원통형 전지셀을 적층하여 전지모듈을 구성하는 구조에 있어서, 상대적으로 각형 전지셀 또는 파우치형 전지셀에 비해 구조적 불안정성을 갖게 된다.Moreover, in the case of the cylindrical battery cell constituting such a battery module, in the structure of forming the battery module by stacking the cylindrical battery cells, there is a relatively structural instability compared to the square battery cell or pouch battery cell.
