본 발명은 전기차 및 하이브리드 차량의 고전압배터리에 있어서 고전압배터리의 온도를 상승/냉각시킴으로써 고전압배터리의 상태를 최적으로 유지토록 하는 차량의 고전압배터리 공조시스템 및 공조방법에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-voltage battery air conditioning system and an air conditioning method for a vehicle that maintains a state of a high-voltage battery at an optimal level by raising / lowering a temperature of a high- voltage battery in a high- voltage battery of an electric vehicle and a hybrid vehicle.

본 발명은 전기차 및 하이브리드 차량의 고전압배터리에 있어서 고전압배터리의 온도를 상승/냉각시킴으로써 고전압배터리의 상태를 최적으로 유지토록 하는 차량의 고전압배터리 공조시스템 및 공조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-voltage battery air conditioning system and an air conditioning method for a vehicle that maintains a state of a high-voltage battery at an optimal level by raising / lowering a temperature of a high- voltage battery in a high- voltage battery of an electric vehicle and a hybrid vehicle.

전기차나 하이브리드 차량, 연료전지 차량 등과 같은 친환경 차량의 경우 차량의 구동을 위해 모터와 고전압배터리를 이용한다. 그러한 충전이나 기타 필요시에는 고전압배터리가 과열되고 겨울철에는 과냉되어 제 성능을 발휘하지 못하고 열화될 수 있는 환경에 놓여있다. 따라서, 이러한 고전압배터리를 효과적으로 공조할 수 있는 기술이 필요하다.In the case of environmentally friendly vehicles such as electric vehicles, hybrid vehicles, and fuel cell vehicles, a motor and a high-voltage battery are used for driving the vehicle. Such charging or other conditions are in an environment where the high voltage battery is overheated in the case of necessity, and undercooling in the winter can not be performed to deteriorate the performance. Therefore, there is a need for a technique capable of effectively cooperating with such a high-voltage battery.

종래의 기술 대부분은 배터리를 냉각하기 위해 기존의 냉매를 활용한 에어컨시스템을 사용함으로써, 냉각된 차량 내부 공기를 흡입하여 배터리로 이송시켜 대류에 의한 배터리 냉각이 되도록 한 기술이 적용되고 있다.Most of the conventional technologies use a conventional air-conditioning system that utilizes refrigerant to cool the battery, so that the air inside the cooled vehicle is sucked and transferred to the battery so that battery cooling by convection is applied.

그러나 이러한 기술은 오히려 실내 냉방 부하 증대의 원인이 되고, 실내가 냉방시라면 필요시 배터리에 난방을 할 수 있는 기능이 불가한 단점이 있었다.However, such a technology has a disadvantage in that it causes an increase in the indoor cooling load, and it is not possible to perform the function of heating the battery if necessary when the indoor is in a cooling state.

한편, 펠티어소자(열전소자)를 이용하여 냉각과 난방이 동시에 되도록 한 배터리 냉/난방 구조의 경우 고전압배터리의 일측면에 펠티어 열교환기를 설치하고 배터리의 외부로 폐열을 공기에 방열하기 위한 핀을 설치하는 것인바, 이 경우에는 폐열을 방열시 방열 성능이 저하되는 구조(AIR TO AIR)인 것이었다.
On the other hand, in the case of a battery cooling / heating structure in which cooling and heating are simultaneously performed using a Peltier element (thermoelectric element), a Peltier heat exchanger is installed on one side of a high voltage battery and a pin for dissipating waste heat to the outside is installed In this case, the structure is such that the heat radiation performance is lowered when the waste heat is dissipated (AIR TO AIR).

상기의 배경기술로서 설명된 사항들은 본 발명의 배경에 대한 이해 증진을 위한 것일 뿐, 이 기술분야에서 통상의 지식을 가진자에게 이미 알려진 종래기술에 해당함을 인정하는 것으로 받아들여져서는 안 될 것이다.
It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.

고전압배터리 하우징은 트렁크룸 내부에 마련되고 제1블로워는 폐열을 트렁크룸 내부로 배출하며, 트렁크룸에는 에어익스트랙트부가 마련될 수 있다.The high voltage battery housing is provided inside the trunk room, the first blower discharges waste heat into the trunk room, and the trunk room can be provided with an air extractor.

고전압배터리 하우징은 밀폐 구조이고, 제1열교환기와 제1블로워는 하우징의 내부에 마련되어 하우징 내부공기를 공조하며 냉각라인의 타측은 하우징을 관통하여 삽입됨으로써 제1열교환기와 결합될 수 있다.The high voltage battery housing is a sealed structure, and the first heat exchanger and the first blower are provided inside the housing to cooperate with the air inside the housing, and the other side of the cooling line can be coupled with the first heat exchanger by being inserted through the housing.

냉각라인은 별도의 구동가 구비되지 않은 냉각수 파이프일 수 있다.The cooling line may be a cooling water pipe without a separate drive.

제1열교환기와 제2열교환기에는 공기와 열교환되는 복수의 방열핀이 마련될 수 있다.The first heat exchanger and the second heat exchanger may be provided with a plurality of heat dissipating fins for heat exchange with air.

제1블로워, 제2블로워, 펠티어소자의 가동을 제어하는 제어부;를 더 포함할 수 있다.A first blower, a second blower, and a controller for controlling the operation of the Peltier element.

제어부는 고전압배터리의 저단냉방 필요시에는 제1블로워와 제2블로워를 가동할 수 있다.The control unit can operate the first blower and the second blower when the low-temperature cooling of the high-voltage battery is required.

제어부는 고전압배터리의 고단냉방 필요시에는 제1블로워, 제2블로워, 펠티어소자를 모두 가동할 수 있다.
The control unit can operate both the first blower, the second blower, and the Peltier element when high-temperature cooling of the high voltage battery is required.

이러한 차량의 고전압배터리 공조시스템을 이용한 공조방법은, 고전압배터리에서 필요한 공조모드를 결정하는 모드결정단계; 및 고단냉방모드의 경우 제1블로워와 제2블로워를 가동하고, 펠티어소자는 일면에서 냉각이 일어나도록 제어하는 고단냉방단계;를 포함한다.The air conditioning method using the high voltage battery air conditioning system of such a vehicle includes: a mode determining step of determining a required air conditioning mode in the high voltage battery; And a high-stage cooling step of operating the first blower and the second blower in the high-temperature cooling mode, and controlling the cooling of the Peltier element to occur on one side.

모드결정단계 이후에는, 저단냉방모드의 경우 제1블로워와 제2블로워만을 가동하는 저단냉방단계;를 더 포함할 수 있다.

상술한 바와 같은 구조로 이루어진 차량의 고전압배터리 공조시스템 및 공조방법에 따르면, 실내 냉난방을 이용하지 않으면서도 펠티어소자의 방열을 충분히 확보함으로써 효과적으로 고전압배터리를 공조할 수 있게 된다.According to the high-voltage battery air conditioning system and the air conditioning method of the vehicle having the above-described structure, the heat discharge of the Peltier element is sufficiently ensured without using the indoor cooling and heating, so that the high-voltage battery can be efficiently air-conditioned.

또한, 펠티어소자의 폐열을 수냉식으로 배출하도록 함으로 인해 공기 배출식 보다 성능이 향상된다(공기 배출 식대비 성능 2~5배 상승).In addition, by discharging the waste heat of the Peltier device by water-cooling, the performance is improved more than that of the air discharge type (the performance of the air discharge rate is increased 2 to 5 times).

그리고, 주 사용 모드에 대해서는 자연 환기 송풍에 의해 열 교환이 되도록 구성하여 최소한의 에너지를 사용토록 구성할 수 있다.In the main use mode, the heat exchange can be performed by natural ventilation air blowing so that the minimum energy can be used.

또한, 냉각된 실내 공기를 사용하지 않음으로써 기존 차량의 에어컨 냉각 부하를 줄일 수 있게 되고, 워터펌프를 사용하지 않기 때문에 연비가 향상된다.
In addition, by not using the cooled room air, the air conditioner cooling load of the existing vehicle can be reduced, and the fuel consumption is improved because the water pump is not used.

본 발명에 따른 차량의 고전압배터리 공조시스템은, 고전압배터리 하우징(120)에 마련된 제1열교환기(300) 및 제1열교환기(300) 주변에서 송풍하는 제1블로워(400); 고전압배터리 하우징(120) 외측 상부에 마련된 제2열교환기(500) 및 제2열교환기(500) 주변에서 송풍하는 제2블로워(600); 일면이 제2열교환기(500)에 접촉되도록 결합된 펠티어소자(800); 및 냉각수가 순환되는 라인으로써, 일측은 펠티어소자(800)의 타면에 접촉되도록 결합되고 하방으로 연장된 후 타측은 제1열교환기(300)와 열교환되도록 결합된 냉각라인(700);을 포함한다.The high voltage battery air conditioning system of a vehicle according to the present invention includes a first heat exchanger 300 provided in the high voltage battery housing 120 and a first blower 400 blowing around the first heat exchanger 300; A second blower 600 blowing around the second heat exchanger 500 and the second heat exchanger 500 provided on the upper side of the high voltage battery housing 120; A Peltier element 800 coupled to one side to be in contact with the second heat exchanger 500; And a cooling line 700 coupled to one side of the Peltier element 800 so as to be in contact with the other side of the Peltier element 800 and to be downwardly extended and then the other side to be heat-exchanged with the first heat exchanger 300 .

도 1과 같이, 차량의 트렁크룸(20)에는 유입구(10)를 통해 실내 내기가 유입되고 이는 주행시 자연대류에 의해 에어익스트랙트부(30)를 통해 외부로 배출된다.As shown in FIG. 1, the indoor air flows into the trunk room 20 of the vehicle through the inlet 10 and is discharged to the outside through the air extract unit 30 by natural convection during traveling.

이러한 트렁크룸(20)에는 친환경 차량의 고전압배터리(100)가 탑재되는데, 고전압배터리 하우징(120)에는 제1열교환기(300)가 마련되고, 제1열교환기(300) 주변에서 송풍하는 제1블로워(400)가 마련된다. 제1블로워(400)는 고전압배터리 하우징(120)의 내부에서 제1열교환기(300)측으로 바람을 송풍함으로써 고전압배터리 하우징(120)의 내부공기가 공조되며 순환될 수 있도록 한다.A high-voltage battery 100 of an eco-friendly vehicle is mounted in the trunk room 20. The high-voltage battery housing 120 is provided with a first heat exchanger 300 and a first heat exchanger 300 for blowing air around the first heat exchanger 300, A blower 400 is provided. The first blower 400 blows air from the inside of the high voltage battery housing 120 toward the first heat exchanger 300 so that the inside air of the high voltage battery housing 120 can be circulated and circulated.

한편, 고전압배터리 하우징(120) 외측 상부에는 제2열교환기(500)가 마련된다. 그리고 제2열교환기(500) 주변에는 송풍용 제2블로워(600)가 마련된다. 도시된 실시예의 경우 제2열교환기(500)는 트렁크룸(20)의 유입구(10)측에 마련되는바, 직접적인 열교환을 피하기 위해 차단판(50)이 마련될 수 있다. 또한 제2열교환기(500)가 트렁크룸(20)의 유입구(10)측에 마련되기 때문에 실내 내기를 바로 빨아들이며 열교환함으로써 펠티어소자(800)의 방열을 용이하게 할 수 있도록 한다. 버려진 폐열은 트렁크룸(20)의 에어익스트랙트부(30)를 통해 외부로 자연 배출되도록 하는 것이다.
On the other hand, a second heat exchanger 500 is provided on the upper side of the high voltage battery housing 120. A second blower 600 for blowing air is provided around the second heat exchanger 500. In the illustrated embodiment, the second heat exchanger 500 is provided on the side of the inlet 10 of the trunk room 20, and a blocking plate 50 may be provided to avoid direct heat exchange. Since the second heat exchanger 500 is provided on the side of the inlet 10 of the trunk room 20, the indoor heat is directly sucked and exchanged by heat, thereby facilitating the heat dissipation of the Peltier element 800. Waste heat is discharged to the outside through the air extract unit 30 of the luggage compartment 20.

한편, 펠티어소자(800)는 전기의 인가에 따라 일면이 냉각시 타면이 가열되고 일면이 가열시 타면이 냉각되는 열전소자로서, 그 일면이 제2열교환기(500)에 접촉되도록 결합된다. 이를 통해 제2열교환기(500)에서의 냉각이 필요한 경우 펠티어소자(800)의 동작에 따라 제2열교환기(500)에서 냉각수를 냉각하게 된다.On the other hand, the Peltier element 800 is a thermoelectric element in which one surface of the Peltier element 800 is heated while the other surface of the Peltier element 800 is cooled, and the other surface thereof is cooled when the other surface is heated. The Peltier element 800 is coupled to the second heat exchanger 500. Accordingly, when the cooling in the second heat exchanger 500 is required, the cooling water is cooled in the second heat exchanger 500 according to the operation of the Peltier element 800. [

한편, 냉각라인(700)은 냉각수가 순환되는 라인으로써, 일측은 펠티어소자(800)의 타면에 접촉되도록 결합되고 하방으로 연장된 후 타측은 제1열교환기(300)와 열교환되도록 결합된다. 그리고 냉각라인(700)은 별도의 구동가 구비되지 않은 냉각수 파이프일 수 있다.On the other hand, the cooling line 700 is a line through which cooling water is circulated. One side of the cooling line 700 is coupled to the other surface of the Peltier element 800 and extends downward, and the other side is connected to heat exchange with the first heat exchanger 300. And the cooling line 700 may be a cooling water pipe which is not provided with a separate drive.

이를 통해 펠티어소자(800)에 의해 냉각된 냉각수는 하방으로 자연스럽게 대류되고, 하방에 있던 냉각수는 제1열교환기(300)에 의해 가열된 상태인바, 자연스럽게 상방으로 대류되며 전체적으로 워터펌프 등이 없어도 냉각수의 순환이 일어나게 된다.
As a result, the cooling water cooled by the Peltier element 800 is naturally convected downward, and the cooling water in the downward direction is heated by the first heat exchanger 300 and naturally upwardly convected. As a whole, Circulation occurs.

한편, 고전압배터리 하우징(120)은 트렁크룸(20) 내부에 마련되고 제1블로워(400)는 폐열을 트렁크룸(20) 내부로 배출하며, 트렁크룸(20)에는 에어익스트랙트부(30)가 마련될 수 있다. 그리고, 고전압배터리 하우징(120)은 밀폐 구조이고, 제1열교환기(300)와 제1블로워(400)는 하우징(120)의 내부에 마련되어 하우징(120) 내부공기를 공조하며 냉각라인(700)의 타측은 하우징(120)을 관통하여 삽입됨으로써 제1열교환기(300)와 결합될 수 있다.The high voltage battery housing 120 is provided inside the trunk room 20 and the first blower 400 discharges waste heat into the trunk room 20. The trunk room 20 is provided with an air extractor 30, May be provided. The high voltage battery housing 120 has a closed structure and the first heat exchanger 300 and the first blower 400 are provided inside the housing 120 to cooperate with the air inside the housing 120, The other side of the first heat exchanger 300 may be coupled with the first heat exchanger 300 by being inserted through the housing 120.

또한, 제1열교환기(300)와 제2열교환기(500)에는 공기와 열교환되는 복수의 방열핀이 마련될 수 있다. 이를 통해 공기와의 열교환이 용이해지도록 한다.
In addition, the first heat exchanger 300 and the second heat exchanger 500 may be provided with a plurality of heat dissipating fins for heat exchange with air. This facilitates heat exchange with the air.

한편, 제1블로워(400), 제2블로워(600), 펠티어소자(800)의 가동을 제어하는 제어부(900);를 더 포함할 수 있다. 고전압배터리(100)의 경우 약한 냉방이나 강한 냉방이 필요에 따라 달리 요구되는데, 제어부(900)는 고전압배터리(100)의 저단냉방 필요시에는 제1블로워(400)와 제2블로워(600)를 가동할 수 있다. 도 1은 이러한 저단냉방의 상황을 나타낸 것으로서, 제1블로워(400)와 제2블로워(600) 만의 가동을 통하여도 어느 정도의 냉각수 대류가 가능하기 때문에 이러한 경우에는 펠티어소자(800)를 가동하지 않음으로써 배터리의 온도를 유지하면서도 연비를 절약할 수 있는 것이다. 대부분의 주행상황에서는 저단냉방만이 필요한바, 펠티어소자와 워터펌프의 구동에 드는 에너지가 절약되어 그 효과가 매우 크다.The controller may further include a controller 900 for controlling the operation of the first blower 400, the second blower 600, and the Peltier element 800. The controller 900 controls the first blower 400 and the second blower 600 when low-temperature cooling of the high-voltage battery 100 is required, Can be operated. FIG. 1 shows the state of the low-temperature cooling. Since cooling water can be convected to a certain degree through only the operation of the first blower 400 and the second blower 600, the Peltier element 800 is not operated This saves fuel economy while maintaining the temperature of the battery. In most driving situations, only lower-stage cooling is required, which saves energy for driving the Peltier device and the water pump, which is very effective.

한편, 도 2와 같이 제어부(900)는 고전압배터리(100)의 고단냉방 필요시에는 제1블로워(400), 제2블로워(600), 펠티어소자(800)를 모두 가동할 수 있다. 이 경우에는 펠티어소자(800)를 통한 적극적인 냉방이 개입된 경우로써, 냉각라인(700) 하방의 냉각수는 더욱 뜨겁고, 펠티어소자(800)측 냉각수는 더욱 차가울 것인바, 대류되는 냉각수의 유량도 함께 증가할 것이다.2, the controller 900 can operate both the first blower 400, the second blower 600, and the Peltier device 800 when high-temperature cooling of the high-voltage battery 100 is required. In this case, the cooling water below the cooling line 700 is hotter, the cooling water on the Peltier element 800 side is cooler, and the flow rate of the cooling water that is convected is also increased It will increase.

즉, 도 3과 같이, 모든 블로워를 작동하지 않는 경우보다 블로워를 작동하는 저단냉방의 경우가 냉각수 유동량이 증가하고, 고단냉방의 경우 온도차가 더욱 심하기 때문에 대류되는 냉각수의 유동량이 가장 많은 것이다.
That is, as shown in FIG. 3, the amount of flow of cooling water increases in the case of low-stage cooling, in which the blower is operated, and the amount of convection cooling water flows in the high-temperature cooling is larger than in the case of not operating all the blowers.

한편, 이러한 차량의 고전압배터리 공조시스템을 이용한 공조방법은, 고전압배터리에서 필요한 공조모드를 결정하는 모드결정단계; 및 고단냉방모드의 경우 제1블로워(400)와 제2블로워(600)를 가동하고, 펠티어소자(800)는 일면에서 냉각이 일어나도록 제어하는 고단냉방단계;를 포함한다. 즉, 저단냉방, 고단냉방, 난방의 모드를 결정하고, 그에 따라 고단냉방모드의 경우 도 2와 같이 제1블로워(400)와 제2블로워(600)를 가동하고, 펠티어소자(800)는 일면에서 냉각이 일어나도록 제어하는 것이다.The air conditioning method using the high voltage battery air conditioning system of the vehicle includes: a mode determining step of determining a necessary air conditioning mode in the high voltage battery; And a high-stage cooling step of operating the first blower 400 and the second blower 600 in the high-temperature cooling mode and controlling the cooling of the Peltier element 800 to occur on one side. In the high-speed cooling mode, the first blower 400 and the second blower 600 are operated as shown in FIG. 2, and the Peltier element 800 is operated in the one-side cooling mode So that cooling is performed.

그리고, 도 1과 같이 저단냉방모드의 경우에는 제1블로워(400)와 제2블로워(600)만을 가동하는 저단냉방단계를 수행하는 것이다.
1, in the case of the low-stage cooling mode, the low-stage cooling step of operating only the first blower 400 and the second blower 600 is performed.

상술한 바와 같은 구조로 이루어진 차량의 고전압배터리 공조시스템 및 공조방법에 따르면, 실내 냉난방을 이용하지 않으면서도 펠티어소자의 방열을 충분히 확보함으로써 효과적으로 고전압배터리를 공조할 수 있게 된다.According to the high-voltage battery air conditioning system and the air conditioning method of the vehicle having the above-described structure, the heat discharge of the Peltier element is sufficiently ensured without using the indoor cooling and heating, so that the high-voltage battery can be efficiently air-conditioned.

또한, 펠티어소자의 폐열을 수냉식으로 배출하도록 함으로 인해 공기 배출식 보다 성능이 향상된다(공기 배출 식대비 성능 2~5배 상승).In addition, by discharging the waste heat of the Peltier device by water-cooling, the performance is improved more than that of the air discharge type (the performance of the air discharge rate is increased 2 to 5 times).

그리고, 주 사용 모드에 대해서는 자연 환기 송풍에 의해 열 교환이 되도록 구성하여 최소한의 에너지를 사용토록 구성할 수 있다.In the main use mode, the heat exchange can be performed by natural ventilation air blowing so that the minimum energy can be used.

또한, 냉각된 실내 공기를 사용하지 않음으로써 기존 차량의 에어컨 냉각 부하를 줄일 수 있게 되고, 워터펌프를 사용하지 않기 때문에 연비가 향상된다.
In addition, by not using the cooled room air, the air conditioner cooling load of the existing vehicle can be reduced, and the fuel consumption is improved because the water pump is not used.
