배터리 모듈용 센싱 모듈 및 그것을 포함하는 센싱 어셈블리{SENSING MODULE FOR BATTERY MODULE AND SENSING ASSEMBLY COMPRISING THIS}TECHNICAL FIELD [0001] The present invention relates to a sensing module for a battery module, and a sensing assembly including the sensing module.

본 발명은 차량용 배터리 모듈의 각 배터리 셀을 센싱하기 위한 센싱 모듈과 이를 포함하는 센싱 어셈블리에 관한 것이다.The present invention relates to a sensing module for sensing each battery cell of a battery module for a vehicle and a sensing assembly including the sensing module.

현재 EV(Electric Vehicle) 및 HEV(Hybrid Electric Vehicle) 차량은 동력원으로서 이차전지를 이용하고, 다수의 배터리 셀이 적층 배열된 배터리 모듈을 기본 단위로 하여 구성된다.2. Description of the Related Art EV (Electric Vehicle) and HEV (Hybrid Electric Vehicle) vehicles are constructed using a secondary battery as a power source and a battery module in which a plurality of battery cells are stacked and arranged as a basic unit.

배터리 모듈은 다수의 배터리 셀이 적층되어 배열되고, 각 배터리 셀의 전압 등의 센싱 및 제어를 위해 센싱 모듈이 결합된다.A plurality of battery cells are stacked and arranged in a battery module, and a sensing module is coupled to sense and control voltage of each battery cell.

각 배터리 셀의 측면에는 전기적 연결을 위한 리드가 형성되고, 리드 간에 겹쳐서 용접을 하거나 별도의 버스바를 용접시켜 연결시키게 된다.A lead for electrical connection is formed on a side surface of each battery cell, and the leads are welded to each other or a separate bus bar is welded and connected.

그리고, 겹쳐진 용접부나 버스바에 센싱 모듈의 센싱 단자가 다시 용접 등의 방식에 의해 연결되게 한다.Then, the sensing terminal of the sensing module is connected to the overlapped welding part or the bus bar by welding or the like again.

이와 같이 센싱 모듈까지 연결을 위해 2차적인 용접 등의 작업을 요하게 되어 공정시 불리하고, 갈수록 배터리의 용량이 증대됨에 따라 용접 작업이 간단하지만은 않으며 그로 인해 불량이 발생할 염려도 존재한다.As a result, it is disadvantageous in the process to require secondary welding or the like for connection to the sensing module, and as the capacity of the battery is increased, the welding operation is not simple, and there is a possibility that defects may occur.

또한, 배터리 모듈 내지 배터리 팩의 용량 증대로 구조가 다양해지면 그에 따라 센싱 모듈도 달리 제작되어야 하는 어려움도 있었다.In addition, when the structure of the battery module or the battery pack increases due to the increase in the capacity thereof, there is a problem that the sensing module must be manufactured differently.

이상의 배경기술에 기재된 사항은 발명의 배경에 대한 이해를 돕기 위한 것으로서, 이 기술이 속하는 분야에서 통상의 지식을 가진 자에게 이미 알려진 종래기술이 아닌 사항을 포함할 수 있다.The matters described in the background art are intended to aid understanding of the background of the invention and may include matters which are not known to the person of ordinary skill in the art.

도 1은 배터리 셀에 리드 탭이 결합된 것을 도시한 것이고, 도 2는 본 발명에 의한 센싱 모듈을 도시한 것이다.FIG. 1 illustrates a lead tab coupled to a battery cell, and FIG. 2 illustrates a sensing module according to an embodiment of the present invention.

이하, 도 1 및 도 2를 참조하여 본 발명의 일 실시예에 의한 배터리 모듈용 센싱 모듈 및 이를 포함하는 센싱 어셈블리를 설명하기로 한다.Hereinafter, a sensing module for a battery module and a sensing assembly including the same according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG.

도 1과 같이 배터리 모듈은 단위 배터리 셀(10)이 적층 배열되어 마련되고, 각각의 배터리 셀(10)의 일 측 또는 양 측에는 리드(lead)가 형성되어 리드에 따라 직렬이나 병렬로 배터리 셀을 배열하게 된다.As shown in FIG. 1, a battery module includes unit cells 10 arranged in a stacked manner, and a lead is formed on one side or both sides of each battery cell 10 so that the battery cells are connected in series or in parallel .

본 발명의 배터리 셀의 리드에는 종래에 리드 간 절곡 및 용접이나 버스바를 부가 용접하는 대신, 리드 탭(10)이 결합된다.In the lead of the battery cell of the present invention, the lead tab 10 is combined with the conventional method of welding instead of inter-lead bending and welding or bus-bar welding.

리드 탭(10)은 후술할 센싱 모듈(20), 보다 구체적으로는 버스바(22)와의 전기적 접합을 위해 각 배터리 셀(1)에 형성시키는 것으로서, 이는 다양한 형상으로 구현이 가능하다.The lead tab 10 is formed in each battery cell 1 for electrical connection with the sensing module 20, more specifically, the bus bar 22 to be described later, and can be implemented in various shapes.

다만, 리드 탭(10)의 기능을 위해서 배터리 셀(1)의 리드와의 결합을 위한 결합부와 버스바(22)와의 결합을 위한 용접부를 가지는 것이 바람직하다.For the function of the lead tab 10, it is preferable to have a weld portion for coupling between the coupling portion for coupling with the lead of the battery cell 1 and the bus bar 22.

결합부는 용접이나 물리적인 결합에 의할 수 있으며, 용접부는 배터리 셀(1)의 측면에 나란한 평면을 갖는 것이 바람직하다.The joint portion may be welded or physically joined, and the welded portion preferably has a plane parallel to the side surface of the battery cell 1. [

그래서, 용접부와 버스바(22)가 면접촉하여 용접 결합하는 데 유리하다.Thus, it is advantageous for the welded portion and the bus bar 22 to be in surface contact with each other and welded together.

이와 같이 리드 탭(10)이 결합된 배터리 셀(1)의 측면으로 도 2와 같은 센싱 모듈(20)이 결합된다.The sensing module 20 as shown in FIG. 2 is coupled to the side surface of the battery cell 1 to which the lead tab 10 is coupled.

센신 모듈(20)은 평판 형태의 하우징(21)에 배터리 셀의 수에 대응하는 수만큼의 버스바(22, busbar)가 구비되고, 버스바(22)와 전기적으로 연결되는 PCB(23)를 포함하여, 버스바(22)가 배터리 셀(1)과 전기적으로 연결됨에 따라 배터리 셀(1)에 대한 정보가 PCB를 통해 BMS(Battery Management System)로 전달되어 배터리 셀을 모니터링 및 제어할 수 있게 한다.The sensing module 20 includes a number of busbars 22 corresponding to the number of battery cells in a flat housing 21 and a PCB 23 electrically connected to the bus bar 22 As the bus bar 22 is electrically connected to the battery cell 1, the information about the battery cell 1 is transferred to the BMS (Battery Management System) through the PCB to monitor and control the battery cell. do.

이와 같이 본 발명의 센싱 모듈(20)은 버스바(22)가 일체로 형성됨으로써, 버스바(22)를 리드 탭(10)엥 용접함으로써 한번에 배터리 셀 간의 연결 및 센싱 모듈과의 연결이 가능하게 한다.As described above, the sensing module 20 of the present invention has a structure in which the bus bar 22 is integrally formed, so that the connection between the battery cells and the sensing module can be performed at a time by welding the bus bar 22 to the lead tab 10 do.

또한, 제조되는 배터리 모듈의 사양에 따라 기존과는 달리 센싱 모듈(20)만 변경하는 것에 의해 대응이 가능하다.In addition, depending on the specifications of the battery module to be manufactured, it is possible to cope with the change only by changing the sensing module 20, unlike the conventional one.

이러한 버스바(22)는 배터리 모듈을 구성하는 배터리 셀(1)의 수와 배열에 따라 구성시키는 것이 가능하다.The bus bars 22 can be configured according to the number and arrangement of the battery cells 1 constituting the battery module.

즉, 도시와 같이 배터리 모듈이 3P 배열되는 경우 도 2와 같이 센싱 모듈이 구성되며, 1P, 2P, 4P 등에 따라 센싱 모듈만 그에 맞게 변경하는 것에 의해 가능해진다.That is, when the battery module is arranged in 3P as shown in FIG. 2, the sensing module is configured as shown in FIG. 2, and only the sensing module is changed according to 1P, 2P, 4P, and so on.

도 3 내지 도 7은 리드 탭에 대한 다양한 응용예를 도시한 것이다.FIGS. 3-7 illustrate various applications for lead taps.

앞서 설명한 바와 같이, 배터리 셀(1)의 리드(2)에 결합시키는 리드 탭(10)은 리드(2)와의 결합을 위한 결합부와 버스바(22)와의 결합을 위한 용접부로 형성된다.The lead tab 10 to be coupled to the lead 2 of the battery cell 1 is formed as a weld portion for coupling the bus bar 22 with the engaging portion for engaging with the lead 2 as described above.

도시와 같이 리드와 직접 결합되는 부분이 결합부에 해당되고, 도시상 좌측면에 해당되는 면이 용접부에 해당되며, 용접부는 배터리 셀(1)의 측면에 나란한 평면으로 형성된다.As shown in the drawing, a portion directly coupled with the lead corresponds to the coupling portion, a surface corresponding to the left side in the drawing corresponds to the weld portion, and the weld portion is formed in a plane parallel to the side surface of the battery cell 1.

그래서, 용접부는 센싱 모듈(20)에 형성된 평탄한 버스바(22)와 맞닿아 면접촉하여 용접 결합시키게 된다.Thus, the welded portion comes into contact with the flat bus bar 22 formed on the sensing module 20, so that the welded portion comes into surface contact with the welded portion.

도 3의 리드 탭(10)은 판재를 'ㄱ'자 형으로 절곡 프레스하여 제작되고, 제작이 용이하고 생산 단가가 낮으며, 용접 결합되는 형태이다.The lead tab 10 shown in FIG. 3 is manufactured by bending and press-molding a plate material into a letter shape, and is easy to manufacture, low in production cost, and welded.

도 4의 리드 탭(10)은 바 형태의 소재를 단조로 성형시켜 제작하고, 챔퍼 적용으로 조립 공정이 용이하며, 리드(2)를 양 측에서 잡아주기 때문에 위치 정렬이 용이하고 품질 확보가 용이하다.The lead tab 10 shown in FIG. 4 is formed by forging a bar-shaped material, and the assembling process is easy by applying a chamfer. Since the lead 2 is held on both sides, Do.

도 5의 리드 탭(10)은 또한 바 형태의 소재를 단조로 성형시켜 제작되고, 제작형상이 도 4의 리드 탭에 비해 단순한 장점이 있다.The lead tab 10 shown in Fig. 5 is also manufactured by forging a bar-shaped material, and has a merit in that the shape of the lead tab 10 is simpler than that of the lead tab shown in Fig.
