효율적인 냉각 및 온도 검출이 가능한 구조를 갖는 배터리 팩Battery pack with structure for efficient cooling and temperature detection

본 출원은 2015년 3월 23에 출원된 한국특허출원 제10-2015-0040021호에 기초한 우선권을 주장하며, 해당 출원의 명세서 및 도면에 개시된 모든 내용은 본 출원에 원용된다.This application claims priority based on Korean Patent Application No. 10-2015-0040021 filed on March 23, 2015, and all the contents disclosed in the specification and drawings of the application are incorporated in this application.

본 발명은 효율적인 냉각 및 온도 검출이 가능한 구조를 갖는 배터리 팩에 관한 것으로서, 좀 더 구체적으로는 배터리 셀의 온도 상승에 따라 뜨거워진 공기의 이동 방향을 고려하고 또한 배터리 팩에 있어서 온도 소자가 설치되는 위치를 함께 고려한 구조를 갖는 배터리 팩에 관한 것이다.The present invention relates to a battery pack having a structure capable of efficient cooling and temperature detection, and more particularly, taking into account the direction of movement of air heated as the temperature of the battery cell rises, and further comprising a temperature element installed in the battery pack. The present invention relates to a battery pack having a structure in which positions are considered together.

배터리를 사용함에 있어서 이차전지의 온도를 확인하는 것은 안전사고 발생의 방지 및 배터리 수명 향상 등의 측면에서 매우 중요하다.In using the battery, it is very important to check the temperature of the secondary battery in terms of preventing a safety accident and improving battery life.

즉, 전자기기의 성능이 날로 향상되어 감에 따라 이에 전력을 공급하는 배터리의 성능 또한 향상되어 가고, 특히 이러한 고성능 전자기기에 사용되는 배터리의 경우 발열량이 매우 커 온도 상승에 적절히 대처하지 못하는 경우 발화/폭발 등의 사고를 유발할 수 있기 때문에 배터리의 냉각 성능 향상을 위한 기술개발의 필요성은 날로 증대되고 있다.In other words, as the performance of electronic devices improves day by day, the performance of the battery that supplies power also increases. Especially, the battery used in such high-performance electronic devices generates a large amount of heat, so that the fire does not respond properly to temperature rise. Since it may cause an accident such as an explosion, the need for technology development for improving the cooling performance of the battery is increasing day by day.

뿐만 아니라, 배터리의 수명은 주변의 온도와 밀접한 관련성이 있어 주변 온도가 극히 저온 또는 고온인 경우에는 이를 확인하여 배터리의 운전(이차전지의 충전/방전을 의미)을 지양하는 것이 배터리 수명의 연장에 큰 도움이 될 수 있다.In addition, the life of the battery is closely related to the ambient temperature. Therefore, when the ambient temperature is extremely low or high temperature, it is necessary to check this to avoid the operation of the battery (meaning charging / discharging of the secondary battery). It can be a big help.

그러나, 배터리의 온도 측정이 정확히 이루어지지 않는 경우, 적절한 시점에 배터리를 가동 또는 가동 중단 시킬 수 없게 되고, 이는 배터리의 수명 감소 혹은 배터리의 사용 불능 상태를 야기할 수 있으며, 특히 배터리의 발열이 심한 경우 발화/폭발과 같은 사고로 이어질 수 있어 문제이다.However, if the temperature measurement of the battery is not accurate, it will not be possible to start or shut down the battery at an appropriate time, which may lead to a decrease in the life of the battery or an unusable state of the battery. This is a problem because it can lead to accidents such as fire / explosion.

It may be manufactured by sealing the edge portion 133 extended to the outside of the cell accommodating portion 132 in a heat-sealed manner while being drawn out to the outside.

한편, 도 2를 참조하면, 상기 카트리지(12)는 그 내부에 수용되는 배터리 셀(13)의 일부가 카트리지(12)의 외측으로 노출될 수 있도록 셀 수용부(132)에 대응되는 영역에 형성된 셀 노출부(121)를 구비한다.Meanwhile, referring to FIG. 2, the cartridge 12 is formed in an area corresponding to the cell accommodating part 132 so that a part of the battery cell 13 accommodated therein may be exposed to the outside of the cartridge 12. The cell exposing portion 121 is provided.

또한, 상기 카트리지(12)는 배터리 셀(13)에 구비된 한 쌍의 전극 리드(134) 각각이 외부로 노출될 수 있도록 그 상부에 형성된 한 쌍의 인출부(122,123)을 구비한다.In addition, the cartridge 12 includes a pair of lead-out portions 122 and 123 formed thereon so that each of the pair of electrode leads 134 provided in the battery cell 13 can be exposed to the outside.

이러한 카트리지(12)는 대략 직사각 형태의 프레임 형상으로 구현될 수 있으며, 복수의 체결 홀(H)을 구비할 수 있다. 복수의 카트리지(12)는 각각이 배터리 셀(13)을 수용한 상태로 이러한 체결 홀(H)을 통해 체결 볼트(미도시) 등과 같은 체결부재가 삽입됨으로써 상호 체결될 수 있다.The cartridge 12 may be implemented in a frame shape having a substantially rectangular shape, and may include a plurality of fastening holes H. The plurality of cartridges 12 may be fastened to each other by inserting fastening members such as fastening bolts (not shown) through the fastening holes H in the state in which the plurality of cartridges 12 accommodate the battery cells 13.

다음은, 도 2와 함께 도 3 내지 도 5를 참조하여 본 발명의 일 실시예에 따른 배터리 팩에 적용되는 카트리지(12)에 구비된 슬릿(S1,S2,S3)들에 대해 설명하기로 한다.Next, the slits S1, S2, and S3 provided in the cartridge 12 applied to the battery pack according to an exemplary embodiment of the present invention will be described with reference to FIGS. 3 to 5 along with FIG. 2. .

또한, 도 3은 도 2의 A 영역을 상세히 나타내는 확대도이고, 도 4는 도 2의 B 영역을 상세히 나타내는 확대도이며, 도 5는, 도 2의 C 영역을 상세히 나타내는 확대도이다.3 is an enlarged view showing region A of FIG. 2 in detail, FIG. 4 is an enlarged view showing region B of FIG. 2 in detail, and FIG. 5 is an enlarged view showing region C of FIG. 2 in detail.

먼저, 도 2와 함께 도 3 및 도 4를 참조하면, 카트리지 하부(12a)에는 적어도 하나 이상의 제1 흡기 슬릿(S1)이 구비될 수 있으며, 마찬가지로 카트리지 측부(12b)에는 적어도 하나 이상의 제2 흡기 슬릿(S2)이 구비될 수 있다.First, referring to FIGS. 3 and 4 together with FIG. 2, at least one first intake slit S1 may be provided at the cartridge lower portion 12a, and similarly, at least one or more second intakes may be provided at the cartridge side 12b. The slit S2 may be provided.

상기 제1 흡기 슬릿(S1) 및 제2 흡기 슬릿(S2)은, 도 1에 도시된 배기 커버(50)에 설치된 배기 팬(51)의 작동 시에 배터리 팩의 외부로부터 냉각 매체, 즉 공기가 카트리지(12)의 내부로 유입될 수 있도록 한다.The first intake slit (S1) and the second intake slit (S2) is a cooling medium, that is, air from the outside of the battery pack when the exhaust fan 51 installed in the exhaust cover 50 shown in FIG. It can be introduced into the cartridge 12.

한편, 도 2와 함께 도 5를 참조하면, 카트리지 상부(12c), 즉 한 쌍의 리드 인출부(122,123)의 사이에 위치한 영역에는 적어도 하나 이상의 배기 슬릿(S3)이 구비될 수 있다.Meanwhile, referring to FIG. 5 along with FIG. 2, at least one exhaust slit S3 may be provided in the cartridge upper portion 12c, ie, an area between the pair of lead extracting portions 122 and 123.

상기 배기 슬릿(S3)은, 도 1에 도시된 배기 커버(50)에 설치된 배기 팬(51)의 작동 시에 흡기 슬릿(S1,S2)을 통해 배터리 팩의 외부로부터 카트리지(12)의 내부로 유입된 냉각 매체, 즉 공기가 배터리 셀(13)에 의해 발생된 열을 빼앗아 다시 카트리지(12)의 외부로 배출되도록 하는 통로의 역할을 할 수 있다.The exhaust slit S3 is moved from the outside of the battery pack to the inside of the cartridge 12 through the intake slits S1 and S2 during operation of the exhaust fan 51 installed in the exhaust cover 50 shown in FIG. 1. The introduced cooling medium, ie, air, may take the role of a passage to take away the heat generated by the battery cell 13 and discharge it to the outside of the cartridge 12 again.

이처럼, 카트리지(12)에서 상대적으로 하부에 위치하는 흡기 슬릿(S1,S2)을 통해 유입된 공기가 배터리 셀(13)을 냉각시키는 과정에서 온도가 상승한 후 다시 상대적으로 상부에 위치하는 배기 슬릿(S3)을 통해 카트리지(12)의 외부로 빠져나가는 것은 온도가 상승한 공기는 상방으로 움직인다는 원리에도 부합하는 것이다.As such, the air introduced through the intake slits S1 and S2 located in the lower part of the cartridge 12 cools the battery cell 13, and after the temperature rises, the exhaust slits again located in the upper part again ( Exiting to the outside of the cartridge 12 through S3) also corresponds to the principle that the air whose temperature has risen moves upward.

즉, 본 발명의 일 실시예에 따른 배터리 팩은, 온도가 상승한 공기의 자연적인 움직임 방향과 일치하는 방향을 따라 공기의 흐름이 더욱 원활해 질 수 있도록 배기 팬(51)을 구동시킴으로써 배터리 팩에 대한 냉각 효율을 크게 상승시킬 수 있는 것이다.That is, the battery pack according to an embodiment of the present invention, by driving the exhaust fan 51 to smoothly flow the air along the direction that matches the natural direction of movement of the air temperature rises to the battery pack It can greatly increase the cooling efficiency.

다시 도 1 및 도 2를 함께 참조하면, 본 발명의 일 실시예에 따른 배터리 팩에 적용되는 히트 싱크(heat sink)(20)는, 셀 카트리지 조립체(10)의 상부에 설치되되 배터리 셀(13)에 구비된 전극 리드(134) 또는 전극 리드(134)와 연결된 리드 컨덕터(14)와 접촉함으로써 배터리 셀(13)로부터 발생되는 열을 외부로 방출한다.Referring again to FIGS. 1 and 2, a heat sink 20 applied to a battery pack according to an embodiment of the present invention may be installed on an upper portion of a cell cartridge assembly 10, but a battery cell 13 may be installed. The heat generated from the battery cell 13 is discharged to the outside by contacting the electrode lead 134 or the lead conductor 14 connected to the electrode lead 134.

물론, 상기 히트 싱크(20)는, 이처럼 배터리 셀(13)의 전극 리드(134)를 통한 열전도에 의해 전달된 열 이외에도, 앞서 설명한 냉각 매체의 순환에 따라 전달된 열을 상방으로 방출하는 기능 역시 수행할 수 있다.Of course, the heat sink 20, in addition to the heat transferred by the heat conduction through the electrode lead 134 of the battery cell 13, as well as the function of discharging upward the heat transferred in accordance with the circulation of the cooling medium described above Can be done.

한편, 본 발명의 도면에 명확히 도시되지는 않았으나, 본 발명의 일 실시예에 따른 배터리 팩은, 상기 히트 싱크(20)에 인접하여 설치되는 온도 소자를 더 구비할 수 있다.Meanwhile, although not clearly shown in the drawings of the present invention, the battery pack according to an embodiment of the present invention may further include a temperature element installed adjacent to the heat sink 20.

이러한 온도 소자는, 히트 싱크(20)를 통해 방출되는 열을 감지하여 배터리 팩에 대한 냉각 프로세스의 수행 및/또는 배터리 팩의 충방전의 지속이나 중단여부에 대한 결정을 할 수 있도록 한다.Such a temperature element senses the heat emitted through the heat sink 20 to make a determination as to whether to perform the cooling process for the battery pack and / or to continue or stop charging and discharging the battery pack.

이러한 냉각 프로세스의 수행 및/또는 배터리 팩의 사용지속 여부에 대한 결정은 감지된 온도에 따라 배터리 팩에서 자체적으로 이루어질 수도 있고, 사용자가 감지된 온도를 확인함으로써 수동으로 이루어질 수도 있는 것이다.The determination of the performance of this cooling process and / or the continued use of the battery pack may be made by the battery pack itself according to the sensed temperature or may be made manually by the user checking the sensed temperature.

상기 온도 소자를 이용한 상기 기능들의 구현을 위해, 온도 소자는 셀 카트리지 조립체(10)의 상부에 설치되는 인쇄회로기판(30)과 전기적으로 연결될 수 있다.In order to implement the functions using the temperature element, the temperature element may be electrically connected to the printed circuit board 30 installed on the cell cartridge assembly 10.

이 경우, 상기 온도 소자는, 히트 싱크(20)에 직접 접촉된 상태로 인쇄회로기판(30)과 전기적으로 연결될 수도 있고, 인쇄회로기판(30) 상에 직접 실장되어 인쇄회로기판(30)을 통해 히트 싱크와 간접적으로 접할 수도 있는 것이다.In this case, the temperature element may be electrically connected to the printed circuit board 30 in a state of being in direct contact with the heat sink 20, and may be mounted directly on the printed circuit board 30 to mount the printed circuit board 30. It may be indirectly in contact with the heat sink.

한편, 상기 온도 소자의 종류는 온도에 따른 전기적 물성 변화로 인해 온도의 변화 수준을 감지할 수 있는 것이라면 특별히 그 종류가 제한되지는 않는다. 상기 온도 소자로는, 예를 들어 온도의 상승에 따라 저항의 값이 점점 작아지는 NTC 소자(negative temperature coefficient device) 또는 온도의 상승에 따라 저항의 값이 점점 커지는 PTC 소자(positive temperature coefficient device) 등이 이용될 수 있다.On the other hand, the type of the temperature element is not particularly limited as long as it can detect the change in temperature due to the change in electrical properties with temperature. Examples of the temperature element include an NTC element (negative temperature coefficient device) in which the value of the resistance gradually decreases as the temperature increases, or a PTC element (positive temperature coefficient device) in which the value of the resistance gradually increases as the temperature increases. This can be used.

한편, 상기 인쇄회로기판(30)은 전극 리드(134) 또는 리드 컨덕터(14)와 연결됨으로써 배터리 셀(13)과 전기적으로 연결될 수 있으며, 또한 인쇄회로기판(30) 상에는 배터리 셀(13)에 대한 관리동작을 수행할 수 있도록 하는 논리회로 칩 등의 소자가 실장되거나 또는 배터리 셀(13)의 관리동작 수행을 위한 별도의 BMS(Batery management system)와 전기적으로 연결될 수도 있다.Meanwhile, the printed circuit board 30 may be electrically connected to the battery cell 13 by being connected to the electrode lead 134 or the lead conductor 14, and may be connected to the battery cell 13 on the printed circuit board 30. A device such as a logic circuit chip for performing a management operation for the battery cell 13 may be mounted or electrically connected to a separate BMS (Batery Management System) for performing the management operation of the battery cell 13.
