Description

하이브리드 전기자동차의 엔진 냉각수를 이용한 배터리 예열 장치Battery preheater using engine coolant of hybrid electric vehicle

본 발명은 모터와 엔진이 함께 설치된 하이브리드 전기자동차에 관한 것으로, 특히 엔진 냉각수를 이용하여 주배터리를 소정의 온도로 예열하여 배터리의 효율을 향상시키기 위한 하이브리드 전기자동차의 엔진 냉각수를 이용한 배터리 예열 장치에 관한 것이다.The present invention relates to a hybrid electric vehicle equipped with a motor and an engine, and more particularly, to a battery preheating apparatus using an engine coolant of a hybrid electric vehicle for improving the efficiency of a battery by preheating a main battery to a predetermined temperature using engine coolant. It is about.

일반적으로 하이브리드 전기자동차는 모터와 내연기관인 엔진을 함께 가진 전기자동차로써 주행거리가 부족한 전기자동차의 단점을 엔진으로 보충하려는 것이다.In general, a hybrid electric vehicle is an electric vehicle having a motor and an engine which is an internal combustion engine. The hybrid electric vehicle is intended to compensate for the shortcomings of the electric vehicle, which lacks mileage.

이러한 하이브리드 전기자동차는 두 가지 종류로 나누어진다.Such hybrid electric vehicles are divided into two types.

하나는 도 1a와 같이, 엔진(5)은 오로지 발전기(6)를 회전하여 주배터리(1)를 충전하는 데만 사용되고 실제 주행에는 모터(4)를 사용하는 직렬식 하이브리드 전기자동차로써 주행거리를 늘린다.One is, as shown in Figure 1a, the engine 5 is only used to charge the main battery 1 by rotating the generator 6 is used in tandem hybrid electric vehicle using a motor (4) to increase the driving distance .

또 다른 하나는 도 1b와 같이, 모터 외 엔진도 주행 동력으로 사용하는 병렬식 하이브리드 전기자동차로써 다시 두 가지 종류로 나누어진다. 보통 엔진(5)으로 주행을 하고 배기가스와 잡음을 피하지 않으면 안되는 특정 지역에서는 엔진(5)을 멈추고 모터(4)로 주행하는 것과, 엔진(5)으로 주배터리(1)를 충전하면서 주행하다가 힘이 필요할 때는 모터(4)의 힘을 빌려 주행성능을 향상시키는 것이다. 전자는 오염물질을 감소시키는 것이, 후자는 연비를 향상시키는 것이 주된 목적이다.The other is a parallel hybrid electric vehicle that uses an engine other than a motor as driving power, as shown in FIG. 1B, and is further divided into two types. In certain areas where the vehicle is usually driven by the engine 5 and exhaust gas and noise must be avoided, the engine 5 is stopped and the motor 4 is driven and the engine 5 is charged while the main battery 1 is charged. While the force is needed to borrow the power of the motor (4) to improve the running performance. The former aims to reduce pollutants and the latter to improve fuel economy.

이와 같이, 직렬식과 병렬식에 관계없이 하이브리드 전기자동차에는 모터와 엔진을 냉각하는 장치가 있으며, 엔진을 냉각시키는 방식에는 일반적인 내연기관 자동차와 마찬가지로, 수냉식이 사용된다.As described above, the hybrid electric vehicle has a device for cooling the motor and the engine regardless of the series and parallel type, and the water cooling type is used for the engine cooling method as in the case of a general internal combustion engine vehicle.

도 2는 엔진을 냉각시키는 방식중 수냉식 냉각장치를 나타낸 것으로, 워터 펌프(21)에 의해 냉각수를 엔진(5)의 실린더 블록 및 실린더 헤드를 둘러싸는 워터 재킷(22)으로, 라디에이터(23)로 끌어들여 방열하며 데워진 물은 또다시 워터 펌프(22)를 이용해 순화시키고 있다. 또한 워터 펌프(22)에는 팬(24)이 설치되어 있어서 강제적으로 라디에이터(23)로 보내 외기를 접촉시켜 방열 효과를 좋게 한다.FIG. 2 shows a water-cooled cooling apparatus in which the engine is cooled. The water pump 21 serves to cool the water into the water jacket 22 surrounding the cylinder block and the cylinder head of the engine 5 to the radiator 23. The water heated and drawn in is radiated again using the water pump 22. In addition, the water pump 22 is provided with a fan 24 forcibly sent to the radiator 23 to contact the outside air to improve the heat dissipation effect.

그리고 하이브리드 전기자동차 주배터리의 전기량(용량)은 온도에 따라 달라진다. 즉, 주배터리의 전기량은 전해액의 온도에 따라 변화되는데, 저온에서는 전기량이 감소되고 온도가 높으면 전기량이 증대된다. 또한, 주배터리의 자기방전(전기부하를 걸지 않은 상태에서 방전되는 것)은 일반적으로 온도가 높아질수록 커지기 때문에 배터리를 어둡고 통풍이 잘되는 시원한 곳에 보관하게 된다.And the electric capacity (capacity) of the hybrid electric vehicle main battery depends on the temperature. That is, the amount of electricity of the main battery changes depending on the temperature of the electrolyte, but at low temperatures, the amount of electricity decreases, and at high temperatures, the amount of electricity increases. In addition, the self-discharge of the main battery (discharged without electric load) generally increases as the temperature increases, so that the battery is stored in a cool, dark and well-ventilated place.

이와 같이, 하이브리드 전기자동차의 주배터리는 온도가 너무 높거나 너무 낮으면 전기량이 줄어드는데, 주배터리의 온도가 높아지는 것은 어둡고 통풍이 잘되는 시원한 곳에 보관하고 냉각팬을 작동시켜서 배터리를 냉각함으로 방지할 수 있지만 겨울에 주배터리의 온도가 낮아져서 시동이 곤란하게 되는 것은 방지하지 못하는 문제점이 있다.As such, the main battery of a hybrid electric vehicle loses its amount of electricity when the temperature is too high or too low. However, a high temperature of the main battery can be prevented by cooling the battery by operating it in a cool, well-ventilated cool place and operating a cooling fan. However, the temperature of the main battery is lowered in winter, there is a problem that can not be prevented from starting difficult.

본 발명의 목적은 상기의 결점을 해소하기 위한 것으로, 하이브리드 전기자동차의 엔진 냉각수를 이용하여 주배터리의 온도를 소정의 온도로 유지하여 배터리의 효율을 향상시키는 하이브리드 전기자동차의 엔진 냉각수를 이용한 배터리 예열 장치를 제공하는 데 있다.An object of the present invention is to solve the above-mentioned drawback, the battery pre-heating using the engine coolant of the hybrid electric vehicle to improve the efficiency of the battery by maintaining the temperature of the main battery to a predetermined temperature using the engine coolant of the hybrid electric vehicle To provide a device.

본 발명은 냉각수를 엔진 내부로 순환시켜 냉각하는 수냉식 엔진 냉각 장치를 가진 하이브리드 전기자동차에 있어서, 고전압을 저장하고 있는 주배터리 가까이에 위치하며, 엔진에서 엔진 냉각용 라디에이터로 흐르는 높은 온도의 냉각수 일부를 순환하여 방열하는 배터리용 라디에이터와; 상기 배터리용 라디에이터의 통풍을 돕는 배터리 팬과; 상기 배터리용 라디에이터로 냉각수를 유입/차단하는 온수밸브와; 상기 주배터리의 온도를 검출하는 배터리 온도센서와; 주배터리의 온도가 소정의 온도를 유지하도록 상기 온수밸브와 배터리 팬의 작동을 제어하는 차량제어부를 포함하여 구성된다.The present invention is a hybrid electric vehicle having a water-cooled engine cooling device for cooling the coolant by circulating the inside of the engine, located near the main battery that stores the high voltage, a portion of the high temperature coolant flowing from the engine to the engine cooling radiator A radiator for battery that circulates and radiates heat; A battery fan to assist ventilation of the battery radiator; A hot water valve for introducing / blocking cooling water to the battery radiator; A battery temperature sensor detecting a temperature of the main battery; It comprises a vehicle control unit for controlling the operation of the hot water valve and the battery fan so that the temperature of the main battery maintains a predetermined temperature.

본 발명의 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 실시예는 도 3에서와 같이, 냉각수를 엔진 내부로 순환시켜 냉각하는 수냉식 엔진 냉각 장치를 가진 하이브리드 전기자동차에 있어서, 고전압을 저장하고 있는 주배터리(1) 가까이에 위치하며, 엔진(5)에서 엔진 냉각용 라디에이터(23)로 흐르는 높은 온도의 냉각수 일부를 순환하여 방열하는 배터리용 라디에이터(31)와; 상기 배터리용 라디에이터(31)의 통풍을 돕는 배터리 팬(32)과; 상기 배터리용 라디에이터(31)로 냉각수를 유입/차단하는 온수밸브(33)와; 상기 주배터리(1)의 온도를 검출하는 배터리 온도센서(34)와; 주배터리(1)의 온도가 제1 소정온도(T1) 보다 낮으면 상기 온수밸브(33)를 열어 냉각수가 배터리용 라디에이터(31)를 통해 순환되도록 하고 배터리 팬(32)을 작동시키며, 주배터리(1)의 온도가 제2 소정온도(T2) 이상이면 상기 온수밸브(33)를 닫아 냉각수가 배터리용 라디에이터(31)에 유입되는 것을 차단하고 배터리 팬(32)을 작동 중지시키는 차량제어부(35)로 구성된다.According to an embodiment of the present invention, in a hybrid electric vehicle having a water-cooled engine cooling device for circulating and cooling coolant into an engine as shown in FIG. 3, the engine is located near a main battery 1 storing high voltage. A battery radiator 31 for circulating and dissipating a part of the high temperature cooling water flowing from the engine cooling radiator 23 in 5); A battery fan (32) which helps ventilation of the battery radiator (31); A hot water valve 33 for introducing / blocking cooling water into the battery radiator 31; A battery temperature sensor 34 for detecting a temperature of the main battery 1; When the temperature of the main battery 1 is lower than the first predetermined temperature T1, the hot water valve 33 is opened to allow cooling water to circulate through the radiator 31 for battery and to operate the battery fan 32. If the temperature of (1) is greater than or equal to the second predetermined temperature T2, the vehicle control unit 35 closing the hot water valve 33 to block the coolant from flowing into the radiator 31 for battery and to stop the operation of the battery fan 32. It is composed of

상기 차량제어부(35)는 엔진(5)이 작동되는 경우, 배터리 온도센서(34)로부터 주배터리(1) 온도를 검출하여 배터리용 라디에이터(31)에 냉각수를 공급하여 주배터리(1)의 온도를 높일 것인지 아닌지를 판단한다.When the engine 5 is operated, the vehicle control unit 35 detects the temperature of the main battery 1 from the battery temperature sensor 34, supplies cooling water to the radiator 31 for the battery, and the temperature of the main battery 1. Determine whether to increase or not.

검출된 주배터리(1)의 온도가 제1 소정온도(T1) 보다 낮으면, 주배터리(1)의 온도가 너무 낮아 시동에 지장이 있으므로, 상기 차량제어부(35)는 온수밸브(33)를 열어서 엔진(5)에서 나오는 높은 온도의 냉각수중 일부를 배터리용 라디에이터(31)에 흐르도록 하고, 배터리 팬(32)을 작동시켜서 배터리용 라디에이터(31)에서 방열이 잘 되도록 한다.If the detected temperature of the main battery 1 is lower than the first predetermined temperature T1, since the temperature of the main battery 1 is too low to prevent starting, the vehicle control unit 35 opens the hot water valve 33. Some of the high temperature cooling water from the engine 5 is opened to flow to the radiator 31 for the battery, and the battery fan 32 is operated to radiate heat from the radiator 31 for the battery.

이에 따라, 상기 배터리용 라디에이터(31)에서 발열되는 열에 의해 주배터리(1)의 온도가 증가하여 전해액의 온도가 증가하여 주배터리(1)의 전기량이 증가하여 시동이 용이하게 된다.Accordingly, the temperature of the main battery 1 is increased by the heat generated from the battery radiator 31, the temperature of the electrolyte is increased, and the amount of electricity of the main battery 1 is increased, so that starting is easy.

또한, 검출된 주배터리(1)의 온도가 점점 증가하여 제2 소정온도(T2) 보다 높으면, 주배터리(1)의 온도가 너무 높아 자기 방전이 많아지게 되므로, 상기 차량제어부(35)는 온수밸브(33)를 닫아 냉각수가 배터리용 라디에이터(31)에 유입되는 것을 차단하고 배터리 팬(32)을 작동 중지시킨다. 그러면, 배터리용 라디에이터(31)에서 방열이 중지되므로 주배터리(1)의 온도는 더 이상 올라가지 않는다. 따라서, 주배터리(1)의 온도 증가로 인한 자기 방전이 증가되는 것을 방지하여 주배터리(1)의 전기량이 줄어드는 것을 방지한다.In addition, when the detected temperature of the main battery 1 gradually increases and is higher than the second predetermined temperature T2, the temperature of the main battery 1 is too high, so that self discharge increases, so that the vehicle controller 35 may be hot water. The valve 33 is closed to block the coolant from entering the radiator 31 for the battery and to stop the battery fan 32. Then, since the heat dissipation is stopped in the radiator 31 for the battery, the temperature of the main battery 1 does not increase any more. Therefore, the self discharge due to the temperature increase of the main battery 1 is prevented from increasing, thereby preventing the amount of electricity of the main battery 1 from decreasing.

본 발명 하이브리드 전기자동차의 엔진 냉각수를 이용한 배터리 예열 장치는 하이브리드 전기자동차의 엔진 냉각수의 열을 이용하여 주배터리의 온도를 소정의 온도로 유지하여 배터리의 효율을 향상시킨 것으로, 주배터리의 온도가 너무 낮아 시동이 걸리지 않는 것을 방지할 수 있는 유용한 것이다.The battery preheating device using the engine coolant of the hybrid electric vehicle of the present invention improves the efficiency of the battery by maintaining the temperature of the main battery at a predetermined temperature using the heat of the engine coolant of the hybrid electric vehicle, and the temperature of the main battery is too high. This is useful to prevent the engine from starting.
