본 발명은 배터리 셀이 수용되는 케이스에 배터리 셀의 온도 측정을 위한 온도센서를 고정하기 용이한 배터리 모듈 케이스 및 이를 포함하는 배터리 모듈에 관한 것이다.The present invention relates to a battery module case for easily fixing a temperature sensor for measuring a temperature of a battery cell in a case in which the battery cell is accommodated, and a battery module including the same.
일반적으로, 이차전지는 일차전지와는 달리 충전 및 방전이 가능하여 디지털 카메라, 휴대폰, 노트북, 하이브리드카와 같은 다양한 분야에 적용되며 활발한 연구가 진행중이다. 이차전지로는 니켈-카드뮴 전지, 니켈-메탈 하이드라이드 전지, 니켈-수소 전지, 리튬 이차전지를 들 수 있다. 그리고 이차전지 중에서도 높은 에너지 밀도와 방전 전압을 가진 리튬 이차전지에 대한 많은 연구가 행해지고 있고 또한 상용화되어 널리 사용되고 있다.In general, secondary batteries, unlike primary batteries, can be charged and discharged and applied to various fields such as digital cameras, mobile phones, laptops, and hybrid cars, and active research is being conducted. Examples of secondary batteries include nickel-cadmium batteries, nickel-metal hydride batteries, nickel-hydrogen batteries, and lithium secondary batteries. Among the secondary batteries, many researches on lithium secondary batteries having high energy density and discharge voltage have been conducted and commercialized and widely used.
또한, 리튬 이차전지는 다양한 형태로 제조가능한데, 대표적인 형상으로는 리튬 이온 전지에 주로 사용되는 원통형(cylinder type) 및 각형(prismatic type)을 들 수 있으며, 최근 들어 각광받는 리튬 폴리머 전지는 유연성을 지닌 파우치형(pouched type)으로 제조되어서, 그 형상이 비교적 자유롭다.In addition, lithium secondary batteries may be manufactured in various forms, and typical shapes include cylindrical and prismatic types, which are mainly used in lithium ion batteries. Made in a pouched type, the shape is relatively free.
이러한 리튬 이차전지는 고출력 대용량의 필요성으로 인해 다수개의 파우치형 배터리 셀을 적층시킨 배터리 모듈(또는 배터리 팩)의 형태로 구성된다. 그리고 배터리 모듈은 다수개의 배터리 셀들이 적층되어 전기적으로 연결되도록 구성되어, 다수개의 배터리 셀들은 이웃하는 배터리 셀의 전극탭이 연결되어 직렬 또는 병렬로 연결된다.The lithium secondary battery is configured in the form of a battery module (or battery pack) in which a plurality of pouch-type battery cells are stacked due to the need for high output large capacity. The battery module is configured such that a plurality of battery cells are stacked and electrically connected to each other, and the plurality of battery cells are connected in series or in parallel by connecting electrode tabs of neighboring battery cells.
이때, 배터리 모듈을 구성하는 배터리 셀은 충,방전이 반복되면서 배터리 셀의 온도가 상승되어 열화가 발생하여 수명이 단축되거나, 또는 파우치 내부에서 가스가 발생하여 부풀어 오르는 스웰링(swelling) 현상으로 인해 폭발 및 발화의 위험성이 존재한다.At this time, the battery cell constituting the battery module is reduced due to the increase in the temperature of the battery cell is repeated as the charge and discharge repeatedly, or due to the swelling phenomenon that the gas generated inside the pouch swelling (swelling) There is a risk of explosion and fire.
이로 인해 배터리 모듈은 충,방전에 따른 배터리 셀들에서 발생되는 열을 냉각시키기 위해 공랭식 도는 냉매식(수냉식)의 냉각 구조가 필요하며, 배터리 셀들의 온도를 측정하여 그 온도에 따라 냉각되는 정도를 조절하거나 배터리 모듈을 제어할 수 있도록 온도센서가 설치된다.As a result, the battery module needs an air-cooled or refrigerant-type (water-cooled) cooling structure to cool the heat generated by the battery cells according to the charging and discharging. The battery module measures the temperature of the battery cells and adjusts the degree of cooling according to the temperature. Or a temperature sensor is installed to control the battery module.
그런데 배터리 모듈은 이와 같이 배터리 셀들의 적층, 고정, 전기적인 연결 및 냉각 구조 등으로 인해 구조가 복잡하여 온도센서를 설치하기 위한 구조 및 위치 선정이 어려우며, 이로 인해 배터리 셀의 정확한 온도를 측정하기 어려운 문제점이 있다.However, since the battery module has a complicated structure due to the stacking, fixing, electrical connection, and cooling structures of the battery cells, it is difficult to select a structure and a location for installing the temperature sensor, which makes it difficult to accurately measure the temperature of the battery cells. There is a problem.

In this case, the cell insertion groove may be formed on the opposite surface of the pair of vertical supports 220. In addition, an interval maintaining part 230 is formed between the pair of vertical supports 220 extending from the bottom surface of the horizontal support 210.
그리고 제2케이스(300)는 길이 방향으로 수평 지지부(310)가 형성되고, 수평 지지부(310)의 양측에는 높이 방향 상측으로 수직 지지부(320)가 형성되며, 수평 지지부(310)의 상면에는 길이 방향으로 셀 삽입홈(301)이 형성된다. 이때, 한 쌍의 수직 지지부(320)의 마주보는 면에도 셀 삽입홈이 형성될 수 있다. 그리고 한 쌍의 수직 지지부(320) 사이에는 수평 지지부(310)의 상면에서 연장되어 간격 유지부(330)가 형성된다.In addition, the second case 300 has a horizontal support part 310 formed in the longitudinal direction, and vertical support parts 320 are formed on both sides of the horizontal support part 310 in an upper direction in the height direction, and a length is formed on an upper surface of the horizontal support part 310.

여기에서 제1케이스(200) 또는 제2케이스(300)의 간격 유지부(230,330)에는 온도센서(400)가 설치되는 온도센서 안치홈(231)이 형성된다. 이하에서는 제1케이스(200)의 간격 유지부(230)에 온도센서 안치홈(231)이 형성되는 것으로 설명한다.Here, a temperature sensor settling groove 231 in which the temperature sensor 400 is installed is formed in the interval maintaining parts 230 and 330 of the first case 200 or the second case 300. Hereinafter, it will be described that the temperature sensor settled groove 231 is formed in the interval maintaining part 230 of the first case 200.

Thus, the sensor line 410 connected to the temperature sensor 400 installed in the temperature sensor settling groove 231 may be easily connected to a battery management system (BMS) outside the cases 200 and 300.
또한, 상기 센서라인 안치홈(211)은 상기 셀 삽입홈(201) 사이를 따라 형성되어, 상기 센서라인 안치홈(211)의 일측은 온도센서 안치홈(231)과 연결되고 타측은 수직 지지부(220)에 형성되는 센서라인 인출공(221)과 연결될 수 있다. 즉, 센서라인 안치홈(211)은 제1케이스(200)의 수평 지지부(210) 하면에 형성되는 셀 삽입홈(201)의 사이를 따라 형성되고, 일측 수직 지지부(220)에 형성되는 센서라인 인출공(221)과 연결되도록 형성될 수 있다. 그리하여 온도센서(400)에 일측이 연결된 센서라인(410)이 제1케이스(210)의 내측에 배치되어 컴팩트하게 형성될 수 있으며, 센서라인(410)의 타측이 외부로 인출되기 용이하게 구성될 수 있다.In addition, the sensor line settling groove 211 is formed along the cell insertion groove 201, one side of the sensor line settling groove 211 is connected to the temperature sensor settling groove 231 and the other side of the vertical support ( It may be connected to the sensor line drawing hole 221 formed in the 220.
