본 발명은 내연기관의 엔진과 배터리의 전원을 이용한 모터를 동력원으로 사용하는 하이브리드 전기자동차(HEV; Hybrid Electric Vehicle)용 배터리팩에 관한 것으로, 더 자세하게는 BMS 보드를 일체로 구비하는 하이브리드 전기자동차용 BMS 보드 일체형 고전압 배터리팩에 관한 것이다.The present invention relates to a battery pack for a hybrid electric vehicle (HEV) using a motor using an engine of an internal combustion engine and a power source of a battery as a power source, and more particularly, for a hybrid electric vehicle having an integrated BMS board. BMS board integrated high voltage battery pack.

하이브리드 전기자동차(HEV; Hybrid Electric Vehicle)는 내연기관의 엔진과 배터리의 전원을 이용한 모터를 동력원으로 사용한다.Hybrid electric vehicles (HEVs) use motors powered by engines and batteries of internal combustion engines as power sources.

최근 하이브리드 전기자동차용 배터리로는 리튬 배터리가 주로 사용되고 있는 실정인 바, 이 리튬 배터리는 액체 전해질을 사용하는 리튬이온(Li-ion) 배터리와 고체 성분인 폴리머 전해질을 사용하는 리튬폴리머(Li-Polymer) 배터리가 있다.Recently, a lithium battery is mainly used as a battery for a hybrid electric vehicle. The lithium battery is a lithium ion (Li-ion) battery using a liquid electrolyte and a lithium polymer (Li-Polymer) using a polymer electrolyte as a solid component. ) There is a battery.

하이브리드 전기자동차에 있어서는 배터리의 필요 용량에 따라 셀(Cell)을 50~100개 정도를 직렬 연결하여 하나의 팩(Pack) 형태로 차량에 장착하게 된다.In the hybrid electric vehicle, 50 to 100 cells are connected in series according to the required capacity of the battery and mounted in a vehicle as a pack.

한편 상기 하이브리드 전기자동차용 고전압 배터리팩은 다수의 배터리 셀(Battery Cell)과 BMS(Battery Management System; 배터리관리시스템) 보드를 구비하게 되는데, 종래에는 배터리 셀과 BMS 보드가 분리되어 있었기 때문에 배터리 셀 전압을 측정하기 위해서는 배터리 셀로부터 BMS 보드까지 케이블을 연결하여야 했다.Meanwhile, the high voltage battery pack for the hybrid electric vehicle includes a plurality of battery cells and a battery management system (BMS) board. In the related art, the battery cell voltage is separated from the battery cell and the BMS board. In order to measure this, a cable was connected from the battery cell to the BMS board.

즉, 도 1에는 종래의 고전압 배터리 팩과 BMS 보드가 분리된 구성도가 도시되어 있는 바, 도 1과 같이 종래에는 고전압 배터리팩(1)에서 배터리 셀 전압을 측정하기 위해서 배터리 셀(2)에서 케이블 터미널(7)을 고정나사(3)로 연결하여 배터리 셀 전압을 센싱하고, 센싱한 배터리 셀 전압을 하네스 케이블(4)을 통해 BMS 보드(6)의 콘넥터(5)로 전달하였다.That is, FIG. 1 shows a configuration diagram in which a conventional high voltage battery pack and a BMS board are separated. As shown in FIG. 1, the battery cell 2 is used to measure the battery cell voltage in the high voltage battery pack 1. The cable terminal 7 was connected to the fixing screw 3 to sense the battery cell voltage, and the sensed battery cell voltage was transferred to the connector 5 of the BMS board 6 through the harness cable 4.

이처럼 종래에는 고전압 배터리팩(1)과 BMS 보드(6)가 분리되어 있고, 배터리 셀(2)의 전압을 측정하기 위해서는 배터리 셀(2)에 케이블 터미널(7)을 연결하여 케이블 전송로를 통해 BMS 보드에 배터리 셀(2) 전압을 전달하였다.As described above, the high voltage battery pack 1 and the BMS board 6 are separated from each other, and in order to measure the voltage of the battery cell 2, a cable terminal 7 is connected to the battery cell 2 through a cable transmission path. The battery cell 2 voltage was transferred to the BMS board.

따라서 종래에는 배터리 셀(2) 전압이 케이블 전송로를 통해 전달됨으로써 선로저항성분 때문에 전압강하가 일어나며, 상기 선로의 케이블 피복이 탈피된 경우 케이블 간에 쇼트(Short)가 발생하여 화재가 일어날 위험성이 잠재되어 있게 되는 문제가 있었다.Therefore, in the related art, the voltage of the battery cell 2 is transmitted through the cable transmission line, so a voltage drop occurs due to the line resistance component, and if the cable covering of the line is peeled off, a short occurs between the cables, which may potentially cause a fire. There was a problem of becoming.

또한 종래에는 고전압 배터리팩(1)과 BMS 보드(6)를 연결해주기 위해 배터리 셀 전압 센싱부 전극, 하네스 케이블, 케이블 터미널, 콘넥터 등의 많은 부품이 사용되므로 원가가 상승되고, 고전압 배터리팩(1)의 부피가 커지게 되는 문제가 있었 다. In addition, since many components, such as a battery cell voltage sensing unit electrode, a harness cable, a cable terminal, and a connector, are used to connect the high voltage battery pack 1 and the BMS board 6, the cost is increased. There was a problem that the volume of) increases.

본 발명은 상기와 같은 종래의 문제점을 감안하여 안출한 것이며, 그 목적이 하이브리드 전기자동차(HEV; Hybrid Electric Vehicle)용 고전압 배터리팩에 BMS 보드를 일체화함으로써 케이블에서 발생하는 선로저항을 최소화시키고, 케이블과 콘넥터, 터미널 등의 원자재를 줄임으로써 원가절감에 기여할 수 있도록 하고, 작업공수를 줄여 생산성을 향상시킬 수 있도록 하며, 고전압 배터리팩의 크기를 줄일 수 있도록 하는 하이브리드 전기자동차용 BMS 보드 일체형 고전압 배터리팩을 제공하는 데에 있는 것이다.The present invention has been made in view of the above-mentioned conventional problems, and its object is to minimize the line resistance generated from the cable by integrating the BMS board in a high voltage battery pack for a hybrid electric vehicle (HEV; High-voltage battery packs with integrated BMS boards for hybrid electric vehicles that can contribute to cost savings by reducing raw materials such as cables, connectors, and terminals, improve productivity by reducing labor, and reduce the size of high-voltage battery packs. It is in providing.

본 발명은 상기의 목적을 달성하기 위하여 고전압 배터리팩의 상단면에 BMS 보드를 조립하되, 고전압 배터리팩의 형상과 전극의 위치와 모양에 맞게 BMS 보드의 단자부를 설계하여 배터리 셀 위에서 고정나사를 이용하여 바로 조립할 수 있도록 하는 것을 특징으로 한다.The present invention is to assemble the BMS board on the upper surface of the high voltage battery pack to achieve the above object, by designing the terminal portion of the BMS board according to the shape and position and shape of the high voltage battery pack using a fixing screw on the battery cell It is characterized in that to be able to assemble immediately.

즉, 본 발명의 하이브리드 전기자동차용 BMS 보드 일체형 고전압 배터리팩은 고전압 배터리팩의 형상과 배터리 셀 전극의 위치와 모양에 맞게 BMS 보드의 단자부를 설계하여 배터리 셀 위에서 고정나사를 이용하여 고전압 배터리 팩의 상단면 에 BMS 보드를 조립한 것이다.That is, the BMS board integrated high-voltage battery pack of the present invention is designed by using the terminal of the BMS board according to the shape of the high-voltage battery pack and the position and shape of the battery cell electrode of the high-voltage battery pack using a fixing screw on the battery cell.
