Description
본 고안은 전기자동차용 배터리 냉각구조에 관한 것으로, 특히 배터리 모듈을 구성하는 각각의 배터리 셀 사이에 알루미늄 또는 마그네슘 재질의 금속재질의 방열판을 각각 삽입하되 상기 각각의 방열판에는 수평방향의 돌출부를 일정간격으로 형성하여 제작함으로써 전기자동차용 배터리의 냉각을 극대화 시킬 수 있도록 한 것을 특징으로 하는 수평돌출부를 갖는 전기자동차용 배터리 냉각구조에 관한 것이다.The present invention relates to a battery cooling structure for an electric vehicle. In particular, a metal heat sink of aluminum or magnesium material is inserted between each battery cell constituting the battery module, and each of the heat sinks has a horizontally spaced protrusion. The present invention relates to a battery cooling structure for an electric vehicle having a horizontal protrusion, characterized in that by maximizing the cooling of the battery for the electric vehicle by forming and manufacturing.
일반적으로 전기자동차는 일정개수의 니켈 매탈 하이드라이드 배터리 모듈이 삽입된다. 상기 배터리는 보통 10여개의 배터리 셀들이 직렬로 연결된 상태를 유지하고 있다.In general, electric vehicles are inserted with a certain number of nickel metal hydride battery module. The battery usually maintains about 10 battery cells connected in series.
여기서 일반적인 자동차에 들어가는 배터리에 있어서, 배터리 셀의 구조는 도 1(A,B)에 나타낸 바와같이, 양극판과 음극판이 각각 존재하며, 납, 안티몬 합금제의 격자 또는 납 칼슘계 기판 중에 납산화물의 분말을 묽은 황산으로 칠하고 풀 모양의 것을 충전하여 건조한 다음 화성(전기 화학처리)을 하면 양극판은 다갈색의 이산화납(PbO2)으로, 음극판은 해면상 납(Pb)의 작용물질로 변화한다. 어느것의 작용물질도 전해액이 극판에 침투할 수 있도록 다공성으로 되어 있으며 극판의 두께는 2mm 또는 3mm의 것이 사용된다. 이때 양극판과 음극판이 서로 단락하면, 배터리내의 에너지가 없어져 버리므로 두 극판의 단락을 방지하기 위해서 비 전도성이며 전해액에 부식되지 않는 다공성의 합성수지로 가공된 섬유판이 양극판간에 삽입된다.Here, in a battery for a general automobile, the structure of the battery cell has a positive electrode plate and a negative electrode plate, respectively, as shown in Figs. 1 (A, B), and lead oxide is contained in a lead or antimony alloy lattice or lead calcium-based substrate. The powder is painted with dilute sulfuric acid, filled with grass, dried, and then chemically treated (electrochemical treatment). The anode plate turns to brown brown lead dioxide (PbO 2 ), and the cathode plate turns to the active substance of spongy lead (Pb). Either substance is porous to allow electrolyte to penetrate the plate and the plate is 2mm or 3mm thick. In this case, when the positive electrode plate and the negative electrode plate are shorted to each other, the energy in the battery is lost, so that a fiber plate processed with a non-conductive, porous synthetic resin that is not corroded to the electrolyte is inserted between the positive electrode plates to prevent the short circuit of the two electrode plates.
한편, 극판군은 도 2에 나타낸 바와같이, 몇장의 극판을 각각 조합시켜 이것에 극주를 용접하여 만든다. 이렇게하여 만들어진 극판군을 단전지(1셀)라고 하며, 완전충전으로 약 2.1볼트의 전압을 발생한다. 따라서 단전지 3개를 직렬로 연결하면 6볼트, 6개를 직렬로 연결하면 12볼트의 배터리가 된다.On the other hand, as shown in Fig. 2, the pole plate group is made by welding several pole plates by combining several pole plates, respectively. The plate group made in this way is called a unit cell (one cell), and generates a voltage of about 2.1 volts when fully charged. Therefore, if three single cells are connected in series, six volts will be connected in series, and six will be 12 volts.
그리고 단전지내의 극판장수는 임의대로 제작할 수 있으나, 일반적으로 자동차용 배터리에서는 양극판의 장수가 단전지당 3-5장이 가장 많으며, 최고 14장 정도까지 정도이다.In addition, the number of pole plates in a unit cell can be arbitrarily produced, but in general, in a car battery, the number of positive plates is 3-5 sheets per cell, up to 14 sheets.
또한 전해액의 비중은 배터리가 완전 충전상태일 때 20도에서 1.246, 1.260, 1.280의 3종류를 사용하며, 열대지에서는 1.240, 온대지에서는 1.260, 한랭지에서는 1.280을 사용하는등 한난에 따라 구분되어져 사용한다.In addition, the specific gravity of the electrolyte is used at 1.20, 1.246, 1.260, and 1.280 at 20 degrees when the battery is fully charged, and it is classified according to the climate such as 1.240 in the tropics, 1.260 in the temperate regions, and 1.280 in the cold regions. do.
이러한 이유는 전해액이 온도에 영향을 많이 받기 때문이며, 특히 묽은 황산의 비중은 온도에 따라 변화하는데, 즉, 온도가 높으면 비중이 작아지고 온도가 낮으면 비중이 커지기 때문이며, 따라서 전해액의 비중은 액온을 함께 기록하거나 표준온도(20도)로 환산하여 나타낼 필요가 있다.This is due to the fact that the electrolyte is highly affected by temperature, and in particular, the specific gravity of dilute sulfuric acid changes with temperature, that is, the higher the temperature, the lower the specific gravity, and the lower the temperature, the higher the specific gravity. It is necessary to record them together or convert them to standard temperature (20 degrees).
배터리 전해액의 비중은 온도 1도의 변화에 대해서 0.0007변화하므로 임의의 온도 t에서는 표준온도 20도로 환산하면 다음과 같다.Since the specific gravity of the battery electrolyte changes by 0.0007 with respect to the change of the temperature of 1 degree, the specific temperature t is converted into the standard temperature of 20 degrees as follows.
S20 = St + 0.0007(t-20), 여기서 S20은 표준온도 20도로 환산한 비중, St는 t도에서 실측비중 t는 측정시의 액온이다.S20 = St + 0.0007 (t-20), where S20 is the specific gravity converted to the standard temperature of 20 degrees, and St is the measured specific gravity t at t degrees.
한편, 비중계에 의한 충전상태의 판정을 보면 전해액의 비중이 1.260이면 100퍼센트 충전된 상태이고, 1.210이면 75퍼센트 충전된 상태이며, 1.150이면 50퍼센트 충전된 상태이고, 1.110이면 25퍼센트 충전된 상태이며, 1.050이면 대부분 0이다.On the other hand, the determination of the state of charge by the hydrometer shows that the electrolyte has a specific gravity of 1.260, 100% charged, 1.210, 75% charged, 1.150, 50% charged, 1.110, 25% charged. , 1.050 is mostly 0.
따라서 배터리가 방전되면 방전량에 비례하여 비중은 저하함을 알 수 있으며, 전해액의 비중을 측정하면 충전상태를 알 수 있다.Therefore, when the battery is discharged, it can be seen that the specific gravity decreases in proportion to the discharge amount, and the state of charge can be known by measuring the specific gravity of the electrolyte.
그렇게 때문에 배터리의 방전상태를 오래 지속하면 여러 가지 고장을 유발하므로 1.200 정도로 저하하면 보충할 필요가 있는 것이다.Therefore, if the discharge state of the battery lasts for a long time, it causes various failures.
도 3(A, B)에 기전력과 전해액의 비중관계를 나타내고, 기전력과 전해액의 온도의 관계를 나타내었는바, 이처럼 전해액의 온도에 따라 기전력의 차이가 발생하기 때문에 배터리 사용할 때에는 일정한 온도를 유지하도록 해야한다.3 (A, B) shows the relationship between the electromotive force and the specific gravity of the electrolyte, and the relationship between the electromotive force and the temperature of the electrolyte is shown. As such, a difference in electromotive force occurs depending on the temperature of the electrolyte, so that a constant temperature is maintained when the battery is used. Should be.
상술한 내용을 종합해보면 결국 배터리는 내부에서 일어나는 화학반응으로 충방전이 이루어 지기 때문에 온도변화에 민감하여 배터리의 각각의 셀 온도가 너무 높아도 안되고 너무 낮아도 안된다는 것을 알 수 있다.In summary, it can be seen that the battery is sensitive to temperature change because the battery is charged and discharged by a chemical reaction occurring inside, so that each cell temperature of the battery should not be too high or too low.
구체적으로 전기자동차에 들어가는 니켈 매탈 하이드라이드 배터리 셀에서 발생하는 전지전압은 약 1.2볼트 정도이며, 화학식은 다음과 같다.Specifically, the battery voltage generated in the nickel metal hydride battery cell in the electric vehicle is about 1.2 volts, and the chemical formula is as follows.
정극반응: xNi(OH)2+ xOH-↔ xNiOOH + xH2O + xePositive reaction: xNi (OH) 2 + xOH - ↔ xNiOOH + xH 2 O + xe
부극반응: Mx + xH2O + xe ↔ MHx + xOH- Negative reaction: Mx + xH 2 O + xe ↔ MHx + xOH -
전체 전지반응: Mx + xNi(OH)2↔ MHx + xNiOOHTotal cell reaction: Mx + xNi (OH) 2 ↔ MHx + xNiOOH
여기서 화살표 오른쪽 방향은 충전반응을 일으키는 식이고, 화살표 왼쪽방향은 방전반응을 일으키는 식이다.The right direction of the arrow represents the charging reaction, and the left direction of the arrow represents the discharge reaction.
그런데 현재 전기자동차에 사용되는 니켈 마그네슘 배터리 역시 고온에서의 성능과 내구성이 문제가 되기 때문에 냉각 시스템이 요구되나, 도 4에 나타낸 바와같이 배터리 모듈(10)을 이루는 셀들(1)이 서로 접촉되는 구조를 이루고 있기 때문에, 비록 배터리 모듈의 양 사이드에 방열판(2)이 있음에도 불구하고 각각의 셀(1)에서 발생하는 열을 막을 수가 없어 냉각효과가 매우 낮은 문제점이 있다.However, a nickel magnesium battery used in an electric vehicle is also required to have a cooling system because performance and durability at high temperatures are a problem, but as shown in FIG. 4, the cells 1 forming the battery module 10 are in contact with each other. Since the heat sink 2 is formed on both sides of the battery module, the heat generated from each cell 1 cannot be prevented, and thus the cooling effect is very low.
따라서 니켈 매탈 하이드라이드 배터리의 충전전시 전지의 온도가 일정수준 이상이 되면 전극반응 이외의 부반응인 가스발생이 일어나며 이 반응에 의해 전해질의 감소현상이 발생하게 되며, 전지의 팽창반응에 의해 전지의 수명과 성능저하 현상이 야기된다.Therefore, when the temperature of the battery becomes higher than a certain level during charging and charging of the nickel metal hydride battery, gas generation, which is a side reaction other than the electrode reaction, occurs, and the decrease of the electrolyte occurs by the reaction, and the life of the battery is caused by the expansion reaction of the battery. And performance degradation phenomenon.
또한 온도가 너무 낮으면 정상적으로 전극반응이 나타나지 않아 배터리는 재대로 충방전을 하지 못한다.In addition, if the temperature is too low, the electrode does not react normally, so the battery cannot charge or discharge.
본 고안은 상기와 같은 문제를 해결코자 하는 것으로, 전지의 냉각 및 히팅조건을 효율화하여 전극반응 이외의 부반응에 의한 가스발생 반응을 줄이고, 정상적으로 전극반응을 유도하여 충방전이 재대로 일어날 수 있도록 하는데 그 목적이 있다.The present invention is to solve the above problems, to reduce the gas reaction reaction by side reactions other than the electrode reaction by improving the cooling and heating conditions of the battery, and to induce the normal electrode reaction so that charge and discharge can occur again Its purpose is.
상기 목적을 달성하기 위한 수단으로,As a means for achieving the above object,
