본 발명은 친환경 자동차에 탑재되는 배터리 모듈에 관한 것으로서, 더욱 상세하게는 배터리 모듈의 단부에 체결되는 커버에 상기 배터리 모듈을 구성하는 각 배터리 셀의 전압을 측정할 수 있는 전압센싱부재와 전압을 센싱하는 회로가 구성된 PCB가 설치된 커버에 전압센싱부재가 설치된 배터리 모듈에 관한 것이다.
The present invention relates to a battery module mounted in an eco-friendly vehicle, and more particularly, a voltage sensing member capable of measuring the voltage of each battery cell constituting the battery module on a cover fastened to the end of the battery module and sensing the voltage It relates to a battery module in which a voltage sensing member is installed on a cover on which a PCB is installed.

전기자동차 또는 하이브리드 자동차와 같은 친환경 자동차에는 전동모터의 구동에 필요한 전원이 충전되는 배터리 모듈이 탑재된다.An eco-friendly vehicle such as an electric vehicle or a hybrid vehicle is equipped with a battery module that charges power required for driving an electric motor.

이러한 배터리 모듈은 배터리 모듈의 슬림화와 원가절감을 달성하기 위해 부품 공용화를 목적으로 규격화된 표준 배터리 모듈이 많이 사용되고 있다.For such battery modules, standardized standard battery modules are widely used for the purpose of common parts in order to achieve slimming and cost reduction of battery modules.

상기 표준 배터리 모듈에는 상기 배터리 모듈을 구성하는 각 배터리 셀을 관리하기 위해서 각 배터리 셀의 전압을 측정해야 한다. 예컨대, 각 배터리 셀에 기계식 또는 전자식 센서를 용접하거나 클립방식으로 체결하고, 각 배터리 셀과 전압을 측정하는 센서를 연결하기 위한 부재 등을 장착하여, 각 배터리 셀의 전압을 측정하고 개별 배터리 셀을 제어한다. 만약, 각 배터리 셀의 전압을 측정하지 못하면, 해당 배터리 셀에 대한 제어가 불가능하여, 충전과 방전을 할 수 없어 배터리 셀로서의 기능을 하지 못한다.In the standard battery module, the voltage of each battery cell must be measured in order to manage each battery cell constituting the battery module. For example, a mechanical or electronic sensor is welded to each battery cell or fastened by a clip method, and a member for connecting each battery cell and a sensor that measures voltage is attached to measure the voltage of each battery cell, Control. If the voltage of each battery cell cannot be measured, control of the battery cell is impossible, and charging and discharging cannot be performed, and thus it cannot function as a battery cell.

한편, 앞서 설명한 바와 같이, 배터리 모듈의 슬림화 및 표준화로 배터리 모듈의 내부에는 배터리 모듈을 구성하는 배터리 셀의 전압을 측정하는 전압센서와 배터리 셀과 전압센서를 연결하는 부재를 설치하기 위한 공간적 제약이 많다 그리고, 배터리 모듈의 내부에 장착하기 위한 공간이 충분치 않아, 장착이 어려워 장착공정이 복잡해지는 문제점이 있다.Meanwhile, as described above, due to the slimming and standardization of the battery module, space constraints for installing a voltage sensor measuring the voltage of the battery cells constituting the battery module and a member connecting the battery cell and the voltage sensor inside the battery module are limited. In addition, there is a problem in that the mounting process is complicated because there is not enough space for mounting inside the battery module.

또한, 상기 배터리 모듈의 내부에서 전압센서가 제대로 설치되지 않으면, 배터리 셀의 고유 전압을 유지하는데도 나쁜 영향을 미쳐 배터리 모듈의 성능저하를 유발하는 문제점이 있다.
In addition, if the voltage sensor is not properly installed inside the battery module, there is a problem in that it adversely affects maintaining the intrinsic voltage of the battery cell, resulting in deterioration of the performance of the battery module.

한편, 하기의 선행기술문헌은 '배터리의 셀 전압 측정 장치'에 관한 것으로서, 직렬 연결된 복수 개의 배터리들 각각의 전압을 측정하는 배터리의 전압 측정 장치에 관한 기술이 개시되어 있다.

Hereinafter, a battery module in which a voltage sensing member is installed in a cover according to the present invention will be described in detail with reference to the accompanying drawings.

본 발명에 따른 배터리 모듈은, 단부에 결합되는 커버(21)의 내부에는, 각 배터리 셀(10)의 단부에 전기적으로 연결되는 복수의 전압센싱부재(23)와, 상기 전압센싱부재(23)와 전기적으로 연결되고, 상기 배터리 셀의 전압을 측정할 수 있는 회로가 구성된 PCB(24)가 설치된다.
The battery module according to the present invention includes a plurality of voltage sensing members 23 electrically connected to the ends of each battery cell 10 and the voltage sensing member 23 in the interior of the cover 21 coupled to the end. The PCB 24 is electrically connected to and configured with a circuit capable of measuring a voltage of the battery cell is installed.

배터리 모듈(1)은 복수의 배터리 셀(10)이 배열되고, 복수로 배열된 배터리 셀(10)의 단부에 커버(21)가 결합된다.In the battery module 1, a plurality of battery cells 10 are arranged, and a cover 21 is coupled to an end of the plurality of battery cells 10 arranged.

상기 배터리 모듈(1)의 단부에 결합되는 커버(21)의 내부에는 각 배터리 셀(10)의 단부와 전기적으로 연결되는 전압센싱부재(23)과, 상기 배터리 셀(10)의 전압을 측정할 수 있는 회로가 구성된 PCB(24)가 설치된다.In the inside of the cover 21 coupled to the end of the battery module 1, a voltage sensing member 23 electrically connected to the end of each battery cell 10 and a voltage of the battery cell 10 are measured. A PCB 24 is installed with a circuit that can be configured.

전압센싱부재(23)는 각 배터리 셀(10)의 단부에 결합되어, 상기 배터리 셀(10)과 PCB(24)를 전기적으로 연결해주는 역할을 한다. 상기 전압센싱부재(23)는 도체로 이루어지고, 단면이 'ㄷ'자 형태로 형성되어 있어서, 상기 배터리 셀(10)의 단부를 파지하는 형태로 접속된다. 따라서, 상기 전압센싱부재(23)는 배터리 셀(10)의 단부에서 전면과 후면, 그리고 측면과 접하고 있어서, 상기 배터리 셀(10)의 전압을 3면에서 측정할 수 있어서 신뢰성을 더 높일 수 있다. 아울러, 상기 전압센싱부재(23)는 상기 커버(21)의 상하방향으로 연장되게 형성되어 있어서, 상기 커버(21)에 장착되는 다른 부재, 예컨대 PCB(24)등에 접속되도록 한다.

That is, a part of the cover 21 is exposed to the outside even when the cover 21 is assembled to the battery module 1, so that it can be connected to the voltage sensing member 23 from the outside through the exposed part. Accordingly, the voltage sensing member 23 and the end of the battery cell 10 are welded from the outside through laser welding or the like through a portion exposed to the outside even after assembling in the voltage sensing member 23 so that the battery cell The bonding force between (10) and the voltage sensing member 23 is increased.

이러한 전압센싱부재(23)는 복수, 즉 상기 배터리 셀(10)과 같은 수로 상기 커버(21)의 내부에 설치됨으로써, 상기 배터리 모듈(1)을 구성하는 각 배터리 셀(10)의 전압을 측정할 수 있도록 한다.A plurality of such voltage sensing members 23 are installed inside the cover 21 in the same number as the battery cells 10 to measure the voltage of each battery cell 10 constituting the battery module 1 To be able to do it.

PCB(24)는 상기 커버(21)의 내부에 장착되고, 전압을 측정할 수 있는 회로가 구성된다. 상기 PCB(24)는 상기 전압센싱부재(23)를 통하여 상기 배터리 셀(10)과 전기적으로 연결된다. 즉 상기 전압센싱부재(23)는 상기 배터리 셀(10)의 단부를 파지하는 형태로 상기 배터리 셀(10)의 일측에 전기적으로 연결되어 있고, 아울러 상기 전압센싱부재(23)가 상기 PCB(24)쪽으로도 연장되어 상기 PCB(24)와 전기적으로 연결됨으로써, 상기 PCB(24)는 상기 배터리 셀(10)과 전기적으로 연결될 수 있다.The PCB 24 is mounted inside the cover 21, and a circuit capable of measuring voltage is configured. The PCB 24 is electrically connected to the battery cell 10 through the voltage sensing member 23. That is, the voltage sensing member 23 is electrically connected to one side of the battery cell 10 in a form of gripping the end of the battery cell 10, and the voltage sensing member 23 is connected to the PCB 24 ) Also extends toward and is electrically connected to the PCB 24, so that the PCB 24 may be electrically connected to the battery cell 10.
