Description
본 발명은 배터리 냉각장치 및 방법에 관한 것으로, 더욱 상세하게는 배터리를 냉각시기 위한 공기통로의 양측에 냉각팬을 구비함으로써 배터리를 효율적으로 냉각시킬 수 있는 배터리 냉각장치 및 방법에 관한 것이다.The present invention relates to a battery cooling device and a method, and more particularly to a battery cooling device and a method that can be efficiently cooled by providing a cooling fan on both sides of the air passage for cooling the battery.
통상적으로, 전기 자동차 혹은 하이브리드 전지자동차에는 대용량의 배터리가 장착된다. 이러한 배터리로는 주로 니켈 메탈 하이드라이드 전지, 리튬이온전지, 리튬이온 폴리머전지 등이 사용되고 있다.Typically, electric vehicles or hybrid electric vehicles are equipped with a large capacity battery. As such batteries, nickel metal hydride batteries, lithium ion batteries, lithium ion polymer batteries and the like are mainly used.
그중, 리튬 이온 폴리머 전지는 다른 전지에 비해 고출력, 고밀도 전지로써 차세대 전지로 각광을 받고 있다.Among them, lithium ion polymer batteries are in the spotlight as next generation batteries as high output and high density batteries compared to other batteries.
하지만, 이러한 배터리들은 온도에 따라 성능이 크게 좌우되며, 특히 고온에서는 전해질 분해가 일어나며, 이에 따라 수명이 현저하게 떨어진다.However, these batteries are highly dependent on their performance, especially at high temperatures, resulting in electrolyte degradation, which significantly reduces their lifetime.
따라서, 이와 같은 배터리의 온도상승을 방지하기 위한 다양한 방법들이 개발되고 있으며, 그 일예가 도1 에 도시된다.Therefore, various methods for preventing such a temperature rise of the battery have been developed, an example of which is shown in FIG.
즉, 배터리(1)가 케이스(2)의 내부에 구비되고, 이러한 케이스(2)에는 배터리(1)를 냉각시키기 위한 공기통로(3)가 배치된다. 그리고, 이러한 공기통로(3)의 후방(Ⅱ)에는 냉각팬(4)이 장착된다.That is, the battery 1 is provided inside the case 2, and the air passage 3 for cooling the battery 1 is disposed in the case 2. The cooling fan 4 is mounted to the rear II of the air passage 3.
따라서, 상기 냉각팬(4)이 구동하는 경우, 공기통로(3)의 내부에 흡입력이 작용하여 공기통로(3)의 전방(Ⅰ)으로부터 공기가 흡입되어 후방(Ⅱ)으로 흐르게 됨으로써, 흐르는 공기들에 의하여 배터리(4)들이 일정 온도 이하로 냉각된다.Therefore, when the cooling fan 4 is driven, suction force acts on the inside of the air passage 3 so that air is sucked from the front I of the air passage 3 and flows to the rear II. By means of which the batteries 4 are cooled below a certain temperature.
그러나, 이러한 구조의 냉각방식은 하나의 냉각팬에 의하여 냉각을 실시하므로 배터리의 온도분포를 줄이는데 한계가 있으며 구조 설정 비용이 많이 소요되는 문제점이 있다.However, the cooling method of such a structure is limited by reducing the temperature distribution of the battery because the cooling is performed by one cooling fan, and there is a problem that the structure setting cost is high.
본 발명의 목적은 상기 전술한 바와 같은 문제점들을 해결하기 위해 창출된 것으로서, 배터리를 냉각시키기 위한 공기통로의 양측에 냉각팬을 각각 구비함으로써 배터리를 효율적으로 냉각시킬 수 있는 전기자동차용 배터리의 냉각장치 및 방법을 제공하는데 있다, An object of the present invention is to solve the problems as described above, the cooling device for an electric vehicle battery that can efficiently cool the battery by having a cooling fan on each side of the air passage for cooling the battery, respectively And providing a method,
상기 목적을 달성하기 위하여, 본 발명은 배터리 인접 위치에 구비되어 그 내부에 공기가 유동함으로써 상기 배터리를 냉각시키는 공기통로와; 상기 공기통로의 유입구측에 구비되어 외부 공기를 흡입시키는 제1 냉각팬과; 상기 공기통로의 유출구에 구비되어 상기 공기통로의 공기를 외부로 배출시키는 제2 냉각팬과; 그리고 상기 배터리의 온도를 감지하여 상기 제1 및 제2 냉각팬을 제어함으로써 배터리를 냉각시키는 제어부를 포함하는 전기 자동차의 배터리 냉각장치를 제공한다.In order to achieve the above object, the present invention includes an air passage provided in the battery adjacent position to cool the battery by flowing air therein; A first cooling fan provided at an inlet side of the air passage to suck outside air; A second cooling fan provided at an outlet of the air passage to discharge the air of the air passage to the outside; And it provides a battery cooling device of an electric vehicle comprising a control unit for cooling the battery by sensing the temperature of the battery to control the first and second cooling fan.
이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예에 따른 전기자동차용 배터리의 냉각장치 및 방법을 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a cooling apparatus and method for an electric vehicle battery according to a preferred embodiment of the present invention.
도2 및 도3 에 도시된 바와 같이, 배터리(Battery;10)의 냉각장치는 케이스(Case;12)의 내부에 적절하게 배치되며, 케이스(12)의 상, 하부에는 공기를 유동시키기 위한 공기통로(15)가 배치된다. As shown in Figures 2 and 3, the cooling device of the battery (10) is appropriately disposed in the case (Case) 12, the air reservoir for flowing air in the upper and lower parts of the case (12) The furnace 15 is arranged.
그리고, 이러한 공기통로(15)는 전방(Ⅰ)에 형성된 유입구(16)로부터 공기가 흡입되어 후방(Ⅱ)에 형성된 유출구(19)로 흐르게 됨으로써 배터리(10)들을 일정 온도 이하로 냉각시킨다. In addition, the air passage 15 sucks air from the inlet 16 formed at the front I and flows to the outlet 19 formed at the rear II to cool the batteries 10 below a predetermined temperature.
또한, 상기 유입구(16) 및 유출구(19)에는 냉각팬(18,20)이 각각 설치됨으로써 공기를 공기통로(15)로 흡입 혹은 배출시킨다.In addition, the inlets 16 and the outlets 19 are provided with cooling fans 18 and 20, respectively, to inhale or discharge air to the air passage 15.
보다 상세하게 설명하면, 상기 배터리 케이스(12)는 그 상부 및 하부에 형성되어 공기가 흐르는 공기통로(15)와, 상기 공기통로(15)의 유입구에 설치되어 공기를 흡입시키는 제1 냉각팬(18)과, 상기 공기통로(15)의 유출구(19)에 설치되어 공기를 배출시키는제2 냉각팬(20)과, 상기 배터리(10)의 온도를 감지하여 상기 제1 및 제2 냉각팬(18,20)을 적절하게 구동시키는 제어부(도시안됨)를 포함한다.In more detail, the battery case 12 is formed in the upper and lower portions of the air passage 15 through which air flows, and a first cooling fan installed in the inlet of the air passage 15 to suck air ( 18, a second cooling fan 20 installed at an outlet 19 of the air passage 15 to discharge air, and a temperature of the battery 10 to sense the temperature of the first and second cooling fans ( And a controller (not shown) for appropriately driving 18,20.
따라서, 상기 제1 및 제2 냉각팬(18,20)이 구동하는 경우, 공기통로(15)의 내부에 흡입력이 작용하여 공기통로(15)의 전방(Ⅰ)으로부터 공기가 흡입되어 후방(Ⅱ)으로 흐르게 됨으로써, 흐르는 공기들에 의하여 배터리(10)들이 일정 온도 이하로 냉각된다.Therefore, when the first and second cooling fans 18 and 20 are driven, suction force acts on the inside of the air passage 15 so that air is sucked from the front (I) of the air passage 15 and the rear (II). As a result, the battery 10 is cooled to a temperature below a predetermined temperature by flowing air.
이때, 상기 제1 및 제2 냉각팬(18,20)은 1단 및 2단의 가감속 제어가 가능한 구조를 갖음으로 온도조건에 따라 공기를 효율적으로 유동시킬 수 있다.At this time, the first and second cooling fans (18, 20) has a structure capable of controlling the acceleration and deceleration of the first and second stages can efficiently flow air according to the temperature conditions.
한편, 상기 배터리(10)의 각 부분에는 배터리(10)의 온도를 감지하는 적어도 하나 이상의 온도센서(T1 내지 T6)가 구비되며, 이러한 온도센서(T1 내지 T6)들은 제어부(도시안됨)와 연결된다.On the other hand, each part of the battery 10 is provided with at least one temperature sensor (T1 to T6) for sensing the temperature of the battery 10, these temperature sensors (T1 to T6) are connected to the control unit (not shown) do.
따라서, 상기 제어부(19)는 상기 온도센서(T1 내지 T6)로부터 신호를 접수함으로써 배터리(10)의 각 부분의 온도를 인식하게 되며, 이러한 신호에 의하여 상기 제1 및 제2 냉각팬(18,20)을 구동시킴으로써 공기통로(15)의 공기 유동량을 조절하여 배터리(10)를 효율적으로 냉각시킬 수 있다.Accordingly, the controller 19 recognizes the temperature of each part of the battery 10 by receiving a signal from the temperature sensors T1 to T6, and the first and second cooling fans 18, By driving 20, the air flow amount of the air passage 15 can be adjusted to efficiently cool the battery 10.
즉, 공기통로(15)의 전방측(Ⅰ)에 설치되는 온도센서(T1,T2)의 온도가 후방측(Ⅱ)보다 높은 경우 상기 제어부(도시안됨)는 제1 냉각팬(18)에 신호를 출력함으로써 제1 냉각팬(18)을 보다 빠르게 회전시킨다. 따라서, 전방측(Ⅰ)의 공기 유입량이 증가함으로써 이 구역의 배터리(10)가 냉각된다.That is, when the temperature of the temperature sensors T1 and T2 installed on the front side I of the air passage 15 is higher than the rear side II, the controller (not shown) signals the first cooling fan 18. The first cooling fan 18 is rotated faster by outputting. Thus, the battery 10 in this zone is cooled by increasing the air inflow amount on the front side I.
반면에, 공기통로(15)의 후방측(Ⅱ)에 설치되는 온도센서(T5,T6)의 온도가 전방측(Ⅰ)보다 높은 경우 상기 제어부(도시안됨)는 제2 냉각팬(20)에 신호를 출력함으로써 제2 냉각팬(20)을 보다 빠르게 회전시킨다. On the other hand, when the temperature of the temperature sensors T5 and T6 installed on the rear side II of the air passage 15 is higher than the front side I, the control unit (not shown) is connected to the second cooling fan 20. By outputting a signal, the second cooling fan 20 is rotated more quickly.
따라서, 후방측(Ⅱ)의 공기 유입량이 증가함으로써 이 구역의 배터리(10)가 냉각된다.Thus, the battery 10 in this zone is cooled by increasing the air inflow amount at the rear side II.
그리고, 전방 및 후방측(Ⅰ,Ⅱ)의 온도가 균일한 상태인 경우에는 상기 제어부(도시안됨)는 제1 및 제2 냉각팬(18,20)을 균일하게 작동시킴으로써 배터리(10)의 전, 후부가 균일하게 냉각되도록 한다.In addition, when the temperature of the front and rear sides I and II is uniform, the controller (not shown) operates the first and second cooling fans 18 and 20 uniformly so that the front of the battery 10 is maintained. The rear part is allowed to cool evenly.
이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예에 따른 전기 자동차의 배터리 냉각장치의 냉각방법에 대하여 더욱 상세하게 설명한다.Hereinafter, a cooling method of a battery cooling apparatus of an electric vehicle according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도2 및 도3 에 도시된 바와 같이, 본 발명이 제안하는 배터리 냉각장치에 의하여 배터리(10)를 냉각하는 경우, 먼저 제어부(도시안됨)는 온도센서(T1 내지 T6)를 통하여 배터리(10)의 각 부위의 온도를 감지하게 된다(S100).2 and 3, in the case of cooling the battery 10 by the battery cooling apparatus proposed by the present invention, first, the controller (not shown) is the battery 10 through the temperature sensors (T1 to T6) It will detect the temperature of each part of (S100).
감지결과, 다음식을 만족하는지 여부를 판단하게 된다(S110).As a result of the detection, it is determined whether the following equation is satisfied (S110).
T1〉T2〉T3〉T4〉T5〉T6 ------식1T1〉 T2〉 T3〉 T4〉 T5〉 T6 ------ Equation 1
즉, T1부위의 온도가 가장 높고 점차로 하강하여 T6의 온도가 가장 낮다고 판단되는 경우, 다음의 조건을 만족하는지를 판단하게 된다(S120).That is, when it is determined that the temperature of the T1 region is the highest and gradually decreases so that the temperature of T6 is the lowest, it is determined whether the following conditions are satisfied (S120).
|(T1+T2)-(T5+T6)|〉2*const1 ----- 식2 (const1:5)(T1 + T2)-(T5 + T6) |> 2 * const1 ----- Equation 2 (const1: 5)
상기 조건을 만족하는 경우, 배터리(10)의 T1 부위가 가장 온도가 높다는 의미이므로 상기 제어부(도시안됨)는 제어신호를 송출하여 상기 제1 냉각팬(18)을 2단 상태로 구동시킨다(S124).If the condition is satisfied, the T1 portion of the battery 10 means the highest temperature, so the controller (not shown) sends a control signal to drive the first cooling fan 18 in a two-stage state (S124). ).
이와 같이, 제1 냉각팬(18)을 2단으로 구동시키면, 공기통로(15)의 전방측(Ⅰ)의 공기의 유량이 증가하게 되므로 이 구역의 온도가 하강함으로써 배터리(10)가 과열되는 것을 방지할 수 있다.As such, when the first cooling fan 18 is driven in two stages, the flow rate of the air on the front side I of the air passage 15 increases, so that the temperature of the region decreases, causing the battery 10 to overheat. Can be prevented.
상기 조건식 2에 해당하지 않는 경우에는 제1 냉각팬을 1 단 상태로 구동시키도록 제어한다(S122).If the conditional expression 2 does not correspond to the control to drive the first cooling fan in the first stage (S122).
한편, 상기 조건식 1에 해당하지 않는 경우에는, 다음의 조건을 만족하는지 여부를 판단하게 된다(S130).On the other hand, if it does not correspond to the conditional formula 1, it is determined whether the following conditions are satisfied (S130).
T1〈T2〈T3〈T4〈T5〈T6 ------식3T1 <T2 <T3 <T4 <T5 <T6 ------ Equation 3
즉, 후방측(Ⅱ)의 온도가 가장 높은지 여부를 판단하게 되며, 이 조건을 만족하는 경우에는 다시 다음의 조건식에 해당하는지를 판단하게 된다(S140).That is, it is determined whether the temperature of the rear side (II) is the highest, and if it satisfies this condition, it is again determined whether it corresponds to the following conditional expression (S140).
|(T1+T2)-(T5+T6)|〉2*const1 ----- 식4(T1 + T2)-(T5 + T6) |> 2 * const1 ----- Equation 4
상기 조건식을 만족하는 경우, 즉 공기통로(15)의 후방측(Ⅱ)의 온도가 상승하는 경우에는 제2 냉각팬(20)을 2단으로 구동하도록 제어한다(S144).When the conditional expression is satisfied, that is, when the temperature of the rear side II of the air passage 15 rises, the second cooling fan 20 is controlled to be driven in two stages (S144).
그리고, 상기 조건식에 해당하지 않는 경우, 즉 온도가 상기한 단계(S144)에 비교하여 낮은 경우에는 제2 냉각팬(20)을 1단 상태로 구동하도록 제어한다(S142). If the conditional expression does not correspond, that is, the temperature is low compared to the above-described step S144, the second cooling fan 20 is controlled to be driven in the first stage (S142).
또한, 상기 조건식 3에 해당하지 않는 경우에는 다음 조건에 해당하는지 여부를 판단하게 된다(S150).In addition, when the conditional expression 3 does not correspond, it is determined whether the following conditions are met (S150).
T1〈T3 & T6〈T4 ----- 식5T1 <T3 & T6 <T4 ----- Equation 5
상기 조건을 만족하는 경우, 즉 배터리(10)의 중간부 온도가 양단부보다 높은 경우 다음 조건에 해당하는지를 판단하게 된다(S160).When the condition is satisfied, that is, when the temperature of the middle portion of the battery 10 is higher than both ends, it is determined whether the following conditions are met (S160).
|T1-T3|〉const2 & |T6-T4|〉const2 ----- 식6T1-T3 |> const2 & | T6-T4 |> const2 ----- Equation 6
이 조건을 만족하는 경우에는 제1 냉각팬(18)을 1단 상태로 제어하고, 일정 시간 동안 시간지연을 하게 된다(S164).If this condition is satisfied, the first cooling fan 18 is controlled in the first stage, and time delay is performed for a predetermined time (S164).
그리고, 제2 냉각팬(20)을 1단 상태로 구동하도록 제어하고 일정 시간 동안 시간지연을 하게 된다(S166).Then, the second cooling fan 20 is controlled to be driven in a first stage and time delay is performed for a predetermined time (S166).
한편, 상기 식 6의 조건에 해당하지 않는 경우에는 제1 냉각팬(18)을 2단 상태로 구동하도록 제어하고 일정 시간동안 시간지연을 하게 된다(S162). On the other hand, if it does not correspond to the condition of Equation 6 is controlled to drive the first cooling fan 18 in a two-stage state and time delay for a predetermined time (S162).
그리고, 제2 냉각팬(20)을 2단 상태로 구동하도록 제어하고 일정 시간동안 시간 지연을 하게 된다.(S163).Then, the second cooling fan 20 is controlled to be driven in a two-stage state and a time delay is made for a predetermined time (S163).
또한, 상기 식5에 해당하지 않는 경우에도(S150) 상기한 바와 같이 제1 냉각팬(18)을 1단 상태로 제어하고, 일정 시간 동안 시간지연을 하게 된다(S164).In addition, even if the equation 5 does not correspond (S150), as described above, the first cooling fan 18 is controlled in a first stage and time delay is performed for a predetermined time (S164).
그리고, 제2 냉각팬(20)을 1단 상태로 구동하도록 제어하고 일정 시간 동안 시간지연을 하게 된다(S166).Then, the second cooling fan 20 is controlled to be driven in a first stage and time delay is performed for a predetermined time (S166).
상기한 바와 같이, 제어부(도시안됨)가 제1 및 제2 냉각팬(18,20)을 각 온도조건에 따라 적절하게 제어함으로써 배터리(10)의 각 부위를 효율적으로 냉각시키게 된다.As described above, the controller (not shown) controls the first and second cooling fans 18 and 20 appropriately according to the temperature conditions, thereby efficiently cooling each part of the battery 10.
상기와 같은 본 발명에 따른 전기자동차용 배터리의 냉각장치 및 방법은 배터리를 냉각시키기 위한 공기통로의 양측에 냉각팬을 각각 설치하여 온도가 상승하는 배터리 구역에 보다 많은 공기를 공급함으로써 배터리를 효율적으로 냉각시킬 수 있는 장점이 있다.The apparatus and method for cooling an electric vehicle battery according to the present invention as described above efficiently installs a cooling fan on both sides of an air passage for cooling the battery, thereby supplying more air to the battery zone in which the temperature rises. There is an advantage that can be cooled.
