Description

방열판이 부착된 배터리 셀 어셈블리{Battery cell assembly with heat sink attached}Battery cell assembly with heat sink attached}

본 발명은 대용량 리튬 이차 전지를 사용하여 제조한 대용량 에너지 저장용 배터리 팩을 충방전 할 때 단 전지(Cell, 셀)를 연결하는 단자 부위에서 발생하는 열을 발산시키는 구조에 관한 것이다. The present invention relates to a structure for dissipating heat generated at a terminal portion connecting a single cell (Cell, cell) when charging and discharging a large capacity energy storage battery pack manufactured using a large capacity lithium secondary battery.

일반적으로 대용량 배터리 팩의 충전 및 방전 전류는, 수 백 암페어에서 수천 암페어가 될 수 있으며 이때 셀의 단자 와 셀 단자를 연결하는 터미널 부위에서 많은 열이 발생 하게 된다. 이 열을 단시간 내에 식혀 주지 않으면 이 열이 셀의 내부로 전달되고 이어서 셀의 온도가 상승하게 되며 이렇게 되면 셀의 성능 저하되고 또한 수명이 단축될 뿐 만 아니라 셀의 폭발 등 안전과 관련된 심각한 문제를 일으키는 원인이 되기도 한다. In general, the charge and discharge current of a large-capacity battery pack can range from several hundred amperes to thousands of amperes, and a lot of heat is generated at a terminal portion connecting a cell terminal to a cell terminal. If the heat is not cooled in a short time, it is transferred to the interior of the cell, which in turn causes the temperature of the cell to rise, which not only degrades the cell and shortens its lifespan, but also causes serious safety-related problems such as cell explosion. It can also cause.

따라서, 본 발명은 상기한 문제점을 해결하기 위하여 제안된 것으로써, 본 발명의 목적은 배터리 팩을 조립할 때 셀과 셀들을 연결하는 단자(Terminal)에 방열판을 부착하여 배터리 팩을 충전 및 방전할 때 셀의 단자 및 연결 터미널 부위에서 발생하는 열을 순간적으로 흡수하여 분산 방출할 수 있도록 하는데 있다.Accordingly, the present invention has been proposed to solve the above problems, an object of the present invention is to charge and discharge the battery pack by attaching a heat sink to the terminal (Terminal) connecting the cells when assembling the battery pack In order to absorb and dissipate heat generated at the terminal of the cell and the terminal part of the cell instantaneously.

It is a figure which shows the state to make.

대용량 배터리 팩의 충전 및 방전 전류는 수 백 암페어에서 수천 암페어가 될 수 있으며 이때 셀의 단자와 셀 단자를 연결하는 터미널 부위에서 많은 열이 발생하게 된다. 이 열을 단시간 내에 식혀주지 않으면 이 열이 셀의 내부로 전달되고 이어서 셀의 온도가 상승하게 되며 이렇게 되면 셀의 성능 저하되고 또한 수명이 단축될 뿐 만 아니라 셀의 폭발 등 안전과 관련된 심각한 문제를 일으키는 원인이 되기도 한다. The charge and discharge current of a large battery pack can range from a few hundred amperes to thousands of amperes, and a lot of heat is generated at the terminal portion connecting the cell terminals to the cell terminals. If this heat is not cooled in a short time, it is transferred to the interior of the cell, which in turn causes the temperature of the cell to rise, which not only reduces the performance of the cell and shortens its lifespan, but also causes serious safety-related problems such as cell explosion. It can also cause.

본 발명에서는 배터리 팩을 조립 할 때 셀과 셀들을 연결하는 단자 (Terminal)에 방열판을 부착하여 배터리 팩을 충전 및 방전할 때 셀의 단자 및 연결 터미널 부위에서 발생하는 열을 순간적으로 흡수하여 분산 방출할 수 있도록 하였다.According to the present invention, when assembling a battery pack, a heat sink is attached to a terminal connecting the cells to the cells, and when the battery pack is charged and discharged, instantaneously absorbs heat generated from the terminal and the connection terminal of the cell to disperse and dissipate it. I could do it.

First, the cell is placed on the cell tray, the cell assembly positive electrode terminal is placed on the positive terminal of the cell, and the cell terminal heat sink is placed on it, and then assembled as shown in FIG. The negative terminal of the cell is also assembled in the same way as the positive electrode.

이렇게 완성된 셀 모듈들을 다수 적층하여 도면 3과 같이 배터리 팩을 조립 한다. 이때 셀과 셀을 연결하는 부스바에도 방열판을 부착하여 배터리 팩 충전 및 방전시 발생하는 열을 발산한다. A plurality of completed cell modules are stacked to assemble a battery pack as shown in FIG. 3. At this time, the heat sink is also attached to the bus bar connecting the cell to dissipate heat generated when the battery pack is charged and discharged.
