일반적으로 자동차, 중장비 등과 같은 내연기관이 탑재되어 사용된다. 이때, 내연기관은 일반적으로 엔진을 포함하며, 화석연료를 제공하여 구동력을 생성할 수 있다. Generally, internal combustion engines such as automobiles and heavy equipment are mounted and used. At this time, the internal combustion engine generally includes an engine, and may provide a fossil fuel to generate a driving force.
그러나 근래에는 화석연료의 고갈과 이차 전지의 기술 개발로 인하여 내연기관과 베터리 팩을 동시에 사용하는 하이브리드 형태가 사용된다. 이러한 하이브리드 형태는 내연기관과 베터리 팩을 동시에 사용하거나 내연기관만 사용하고 베터리 팩에는 에너지를 저장하는 등 다양한 제어방법과 구조를 통하여 고효율의 장치를 제공할 수 있다. However, in recent years, due to the depletion of fossil fuel and the development of secondary battery technology, a hybrid type using an internal combustion engine and a battery pack is used. This hybrid type can provide a high efficiency device through various control methods and structures, such as using an internal combustion engine and a battery pack at the same time or using only an internal combustion engine and storing energy in the battery pack.
베터리 팩은 온도에 따라서 성능이나 수명에 영향을 받음으로써 베터리 팩의 온도를 조절하는 것은 상당히 중요한 문제이다. 이를 해결하기 위하여 다양한 방법이나 구조들이 개발되고 있다. Since battery packs are affected by performance and lifetime depending on temperature, it is very important to control the temperature of the battery pack. To solve this problem, various methods or structures have been developed.

However, hereinafter, the control unit 170 will be described in detail with reference to a case where the control unit 170 is formed in the form of a circuit board for convenience of description.
한편, 상기와 같은 베터리 팩(110)은 일정한 온도 범위를 벗어나는 경우 작동이 어려울 수 있다. 예를 들면, 베터리 팩(110)이 최하온도 미만이 되는 경우 베터리 셀(111) 내부의 전해질 등이 굳거나 하는 등의 이유로 베터리 셀(111)의 성능이 저하될 수 있다. 반면, 베터리 팩(110)이 최대온도를 초과하는 경우 베터리 셀(111)의 전해질 등이 가열됨으로써 베터리 셀(111) 내부에서 반응이 일어날 때 화재, 폭발 등이 발생할 수 있는 위험이 있다. 따라서 베터리 셀(111)은 일정한 온도범위에서 온도가 조절되어야 한다. 이때, 베터리 온도조절 시스템(100)의 작동을 통하여 상기와 같은 문제를 해결할 수 있다. On the other hand, the battery pack 110 as described above may be difficult to operate when out of a certain temperature range. For example, when the battery pack 110 is less than the lowest temperature, the performance of the battery cell 111 may be deteriorated due to hardening of an electrolyte or the like in the battery cell 111. On the other hand, when the battery pack 110 exceeds the maximum temperature, the electrolyte, etc. of the battery cell 111 is heated, so that there is a risk that a fire, an explosion, or the like may occur when a reaction occurs in the battery cell 111. Therefore, the battery cell 111 has to be controlled in a certain temperature range. At this time, through the operation of the battery temperature control system 100 can solve the above problems.
구체적으로 베터리 온도조절 시스템(100)이 작동하는 경우를 살펴보면, 상기와 같은 시스템에서는 내연기관(143) 및 베터리 팩(110) 중 적어도 하나가 작동하여 동력을 생성할 수 있다. 예를 들면, 자동차에 베터리 온도조절 시스템(100)이 탑재된 경우 내연기관(143)을 통하여 자동차가 구동할 수 있으며, 베터리 팩(110)에서 공급되는 전류를 통하여 자동차가 구동되는 것도 가능하다. 또한, 내연기관(143) 및 베터리 팩(110)이 동시에 작동하여 자동차를 구동하는 것도 가능하다. 이때, 상기와 같은 경우에 한정되는 것은 아니며, 내연기관(143)이 작동하여 구동력을 생성하고, 일부를 베터리 팩(110)에 저장하는 것도 가능하다. Specifically, referring to the case in which the battery temperature control system 100 operates, in the system as described above, at least one of the internal combustion engine 143 and the battery pack 110 may operate to generate power. For example, when the battery temperature control system 100 is mounted on the vehicle, the vehicle may be driven through the internal combustion engine 143, and the vehicle may be driven through the current supplied from the battery pack 110. In addition, the internal combustion engine 143 and the battery pack 110 may be operated at the same time to drive a car. In this case, the present invention is not limited thereto, and the internal combustion engine 143 may operate to generate a driving force, and may store a part in the battery pack 110.
상기와 같이 내연기관(143) 및 베터리 팩(110) 중 적어도 하나가 작동하는 경우 센서유닛(150)는 베터리 팩(110)의 내부온도를 측정할 수 있다.(S110 단계)When at least one of the internal combustion engine 143 and the battery pack 110 operates as described above, the sensor unit 150 may measure the internal temperature of the battery pack 110.
이때, 제어유닛(170)은 센서유닛(150)에서 측정한 베터리 팩(110)의 내부온도가 기 설정된 범위 내인지 판단할 수 있다.(S120단계) 특히 기 설정된 범위는 최하온도 이상이면서 최대온도 이하일 수 있다. 최하온도와 최대온도는 시험 등을 통하여 상기와 같이 베터리 팩(110)이 정상적으로 작동하는 온도 범위로써 제어유닛(170)에 기 설정된 상태일 수 있다. At this time, the control unit 170 may determine whether the internal temperature of the battery pack 110 measured by the sensor unit 150 is within a preset range. (Step S120) In particular, the preset range is equal to or lower than the minimum temperature and the maximum temperature. It may be: The lowest temperature and the maximum temperature may be in a preset state in the control unit 170 as a temperature range in which the battery pack 110 operates normally as described above.
상기와 같이 측정한 내부온도가 최하온도 이상이면서 최대온도 이하인 경우 제어유닛(170)은 현재 상태를 그대로 유지시킬 수 있다.(S130단계)If the internal temperature measured as described above is above the minimum temperature and below the maximum temperature, the control unit 170 may maintain the current state.
한편, 내연기관(143) 및 베터리 팩(110) 중 적어도 하나가 작동하는 경우 베터리 팩(110)의 내부온도가 상기 최대온도를 초과할 수 있다. 이때, 제어유닛(170)은 압축기(132)와 응축기(133)를 작동시켜 냉매를 냉각시킨 후 제1 순환배관(131)을 통하여 제1 유로(121a)로 냉매를 공급시킬 수 있다. 상기와 같이 공급된 냉매는 제1 유로(121a)를 통과하면서 베터리 팩(110)의 온도를 하강시킬 수 있다.(S141단계)On the other hand, when at least one of the internal combustion engine 143 and the battery pack 110 is operated, the internal temperature of the battery pack 110 may exceed the maximum temperature. In this case, the control unit 170 may operate the compressor 132 and the condenser 133 to cool the refrigerant, and then supply the refrigerant to the first flow passage 121a through the first circulation pipe 131. The coolant supplied as described above may lower the temperature of the battery pack 110 while passing through the first flow passage 121a.
또한, 제어유닛(170)은 센서유닛(150)에서 측정된 내부온도 및 내부습도를 근거로 베터리 팩(110)의 내부의 이슬점온도를 산출할 수 있다.(S142단계) 이후 제어유닛(170)은 베터리 팩(110)의 내부의 이슬점온도 이하인지 판단할 수 있다.(S143단계) 특히 상기와 같은 경우 베터리 팩(110)의 내부온도가 이슬점온도 이하로 내려가는 경우 베터리 팩(110)의 내부에 이슬이 맺힘으로써 베터리 셀(111)의 오작동을 유발할 수 있다. 따라서 제어유닛(170)은 센서유닛(150)에서 측정된 온도가 베터리 팩(110)의 내부의 이슬점온도 이하로 내려가는 경우 열전도유닛(160)을 통하여 베터리 팩(110)의 내부를 가열시킬 수 있다.(S151단계)In addition, the control unit 170 may calculate the dew point temperature of the battery pack 110 based on the internal temperature and the internal humidity measured by the sensor unit 150. (Step S142) After the control unit 170 In operation S143, the battery pack 110 may determine whether or not the internal temperature of the battery pack 110 is lower than the dew point temperature. Condensation may cause malfunction of the battery cell 111. Therefore, the control unit 170 may heat the inside of the battery pack 110 through the heat conduction unit 160 when the temperature measured by the sensor unit 150 falls below the dew point temperature of the inside of the battery pack 110. (Step S151)
반면, 내부온도가 이슬점온도를 초과하는 것으로 판단되면, 제어유닛(170)은 내부온도가 기 설정된 설정조건에 해당하는지 판단할 수 있다.(S144단계) On the other hand, if it is determined that the internal temperature exceeds the dew point temperature, the control unit 170 may determine whether the internal temperature corresponds to a predetermined set condition (step S144).
구체적으로 상기와 같이 베터리 팩(110)의 온도가 하강하는 동안 센서유닛(150)은 베터리 팩(110)의 온도를 측정하여 제어유닛(170)으로 전송할 수 있다. 이때, 제어유닛(170)은 센서유닛(150)의 온도가 기 설정된 최대온도 이하로 하강하는지 판단할 수 있다. Specifically, as described above, while the temperature of the battery pack 110 decreases, the sensor unit 150 may measure the temperature of the battery pack 110 and transmit it to the control unit 170. At this time, the control unit 170 may determine whether the temperature of the sensor unit 150 falls below a preset maximum temperature.
이후 제어유닛(170)은 센서유닛(150)에서 측정된 온도가 기 설정된 최대온도 이하로 하강, 기 설정된 온도범위 내부로 진입 또는 기 설정된 설정온도와 동일해지는 경우 등과 같이 내부온도가 설정조건에 도달하면 압축기(132)와 응축기(133)의 작동을 중지시킬 수 있다. Then, the control unit 170 reaches the set condition such as when the temperature measured by the sensor unit 150 falls below the preset maximum temperature, enters into the preset temperature range, or becomes equal to the preset set temperature. If the compressor 132 and the condenser 133 can be stopped.
반면, 제어유닛(170)은 내부온도가 설정조건과 동일하지 않은 것으로 판단되면, 상기에서 설명한 베터리 팩(110)의 내부온도를 측정(S110단계)한 후 각 단계를 다시 수행할 수 있다. On the other hand, if it is determined that the internal temperature is not the same as the set condition, the control unit 170 may perform each step again after measuring the internal temperature of the battery pack 110 described above (step S110).
한편, 상기와 같은 경우 이외에 베터리 팩(110)의 내부온도가 최하온도 미만으로 떨어지는 경우 베터리 온도조절 시스템(100)은 베터리 팩(110)의 내부온도를 증가시킬 수 있다. On the other hand, in addition to the above case when the internal temperature of the battery pack 110 falls below the lowest temperature, the battery temperature control system 100 may increase the internal temperature of the battery pack 110.
구체적으로 센서유닛(150)에서 측정된 베터리 팩(110)의 내부온도가 최하온도 미만인 것으로 판단되면, 제어유닛(170)은 제1 방향전환밸브(145a) 및 제2 방향전환밸브(145b)를 제어할 수 있다.(S161단계) Specifically, when it is determined that the internal temperature of the battery pack 110 measured by the sensor unit 150 is less than the lowest temperature, the control unit 170 controls the first direction switching valve 145a and the second direction switching valve 145b. Can be controlled (step S161).
예를 들면, 제어유닛(170)은 제2 순환배관(141)에 열매체가 흐르고, 안내배관(144)에서 제2 순환배관(141)으로 열매체가 공급되지 않도록 제1 방향전환밸브(145a)를 제어할 수 있다. For example, the control unit 170 controls the first direction switching valve 145a so that the heat medium flows in the second circulation pipe 141 and the heat medium is not supplied from the guide pipe 144 to the second circulation pipe 141. Can be controlled.
또한, 제어유닛(170)은 내연기관(143)에서 토출된 열매체가 제2 순환배관(141)을 통하여 히터(146)로 공급되고, 안내배관(144)으로 공급되지 않도록 제2 방향전환밸브(145b)를 제어할 수 있다. In addition, the control unit 170 is supplied to the heater 146 through the second circulation pipe 141, the heat medium discharged from the internal combustion engine 143, the second direction switching valve (144) 145b) can be controlled.
상기와 같이 제1 방향전환밸브(145a)와 제2 방향전환밸브(145b)가 제어되는 경우 열매체는 내연기관(143)을 통하여 히터(146)를 거쳐 제2 히트싱크(122)로 공급되고, 제2 히트싱크(122)를 거친 후 다시 내연기관(143)으로 이동할 수 있다. When the first direction switching valve 145a and the second direction switching valve 145b are controlled as described above, the heat medium is supplied to the second heat sink 122 via the heater 146 through the internal combustion engine 143, After passing through the second heat sink 122, it may move back to the internal combustion engine 143.
제어유닛(170)은 상기와 같은 작업이 진행되는 동안 베터리 팩(110)의 내부온도가 기 설정된 온도범위에 포함, 기 설정된 설정온도와 동일 또는 최하온도 이상 등과 같이 기 설정된 상태가 되도록 히터(146)를 제어할 수 있다.(S162단계) 이때, 제어유닛(170)은 히터(146)의 제어를 위하여 내연기관(143)에서 토출되는 열매체의 온도를 측정하여 이를 근거로 사용할 수 있다. 특히 상기와 같은 경우 제2 순환배관(141)에는 별도의 센서가 설치될 수 있다. 다른 실시예로써 제어유닛(170)은 히터(146)를 가동시킴으로써 열매체를 가열시키는 것도 가능하다. The control unit 170 is a heater 146 such that the internal temperature of the battery pack 110 is included in the preset temperature range during the operation as described above, such that the internal temperature of the battery pack 110 is in a preset state, such as the preset temperature or more than the lowest temperature. In this case, the control unit 170 may measure and use the temperature of the heat medium discharged from the internal combustion engine 143 for the control of the heater 146. In particular, in the case described above, a second sensor may be installed in the second circulation pipe 141. In another embodiment, the control unit 170 may heat the heating medium by operating the heater 146.
상기와 같이 가열된 열매체는 제2 히트싱크(122)에 공급되어 베터리 팩(110)을 가열시킬 수 있다. 이때, 베터리 팩(110)의 내부온도는 상승하여 최하온도를 넘을 수 있다. The heated heating medium may be supplied to the second heat sink 122 to heat the battery pack 110. At this time, the internal temperature of the battery pack 110 may rise to exceed the lowest temperature.
상기의 과정이 진행되는 동안 제어유닛(170)은 내부온도가 기 설정된 설정조건과 동일한지 판단할 수 있다. 이때, 기 설정된 설정조건은 상기에서 설명한 것과 같이 내부온도가 기 설정된 온도범위에 포함, 기 설정된 설정온도와 동일 또는 최하온도 이상 등과 같은 다양한 조건일 수 있다. While the above process is in progress, the control unit 170 may determine whether the internal temperature is equal to a preset set condition. In this case, the preset setting condition may be various conditions such that the internal temperature is included in the preset temperature range, the same as the preset setting temperature or more than the lowest temperature as described above.
제어유닛(170)은 내부온도가 기 설정된 설정조건과 동일한 경우 제어를 종료할 수 있다. 또한, 제어유닛(170)은 내부온도가 기 설정된 설정조건과 상이한 경우 상기에서 설명한 것과 같이 베터리 팩(110)의 내부온도를 측정한 단계부터 다시 각 단계를 수행할 수 있다. The control unit 170 may terminate the control when the internal temperature is the same as a preset set condition. In addition, when the internal temperature is different from the preset setting condition, the control unit 170 may perform each step again from the step of measuring the internal temperature of the battery pack 110 as described above.
상기와 같은 제어는 자동차 등과 같은 장치가 작동할 때 베터리 팩(110)이 작동하는 경우 지속적이고 반복적으로 수행될 수 있다. 이때, 상기와 같은 제어는 베터리 팩(110)의 내부온도가 최하온도 이상이면서 최대온도 이하인 경우 수행되지 않을 수 있으며, 베터리 팩(110)의 내부온도가 최하온도 미만이거나 최대온도를 초과하는 경우 수행될 수 있다. 특히 센서유닛(150)는 베터리 팩(110)의 내부온도를 지속적으로 측정하여 제어유닛(170)에 피드백할 수 있다. Such control may be performed continuously and repeatedly when the battery pack 110 operates when a device such as a vehicle operates. In this case, the control as described above may not be performed when the internal temperature of the battery pack 110 is less than the maximum temperature and less than the maximum temperature, and is performed when the internal temperature of the battery pack 110 is less than the minimum temperature or exceeds the maximum temperature. Can be. In particular, the sensor unit 150 may continuously measure the internal temperature of the battery pack 110 to feed back to the control unit 170.
