본 발명은 하이브리드 차량의 고전압배터리 냉각 제어 방법에 관한 것으로서, 더욱 상세하게는 배터리의 열화된 정도를 판단하여, 냉각팬이 배터리의 냉각에 필요한 풍량만을 정확히 제공함으로써, 냉각팬이 사용하는 에너지를 최소화하는 동시에 하이브리드 파워의 최대 활용을 도모할 수 있도록 한 하이브리드 차량의 고전압배터리 냉각 제어 방법에 관한 것이다.The present invention relates to a high voltage battery cooling control method of a hybrid vehicle, and more particularly, to determine the degree of deterioration of the battery, the cooling fan accurately provides only the amount of air required for cooling the battery, thereby minimizing the energy used by the cooling fan At the same time, the present invention relates to a high voltage battery cooling control method of a hybrid vehicle that enables maximum utilization of hybrid power.
하이브리드 차량의 고전압배터리 냉각 시스템은 첨부한 도 1에 도시된 바와 같이 냉각팬에 의한 구동과 동시에 냉각공기가 고전압배터리 모듈내를 통과하여, 고전압배터리의 냉각이 이루어지는 구조로 되어 있고, 상기 고전압배터리 냉각 시스템을 제어하기 위한 종래의 방식은 BOL(BEGINNING OF LIFE)기준으로 냉각 제어 설계가 되어 있다.The high voltage battery cooling system of the hybrid vehicle has a structure in which cooling air passes through the high voltage battery module simultaneously with driving by a cooling fan to cool the high voltage battery, as shown in FIG. 1. The conventional method for controlling the system is a cooling control design based on BGI (BEGINNING OF LIFE).
이러한 고전압배터리의 냉각 제어 시스템의 역할은 배터리의 항온을 유지시 켜 줌으로써, 고전압배터리가 차량에 안정적인 파워를 용이하게 전달할 수 있도록 하는데 있다.The role of the cooling control system of the high voltage battery is to maintain a constant temperature of the battery, so that the high voltage battery can easily deliver stable power to the vehicle.
상기 고전압배터리의 냉각 제어 시스템에서의 제어는 배터리 제어기인 BMS(Battery Management System)에서 담당하고 있으며, 이 BMS는 배터리를 냉각시키기 위한 냉각공기의 온도와 배터리의 현재 온도를 측정하여 냉각팬의 적정한 풍량을 단수별로 제어하면서 배터리의 냉각 제어를 관장한다.The control of the high voltage battery in the cooling control system is in charge of the battery controller BMS (Battery Management System), the BMS measures the temperature of the cooling air for cooling the battery and the current temperature of the battery to determine the appropriate amount of air flow of the cooling fan It controls the cooling control of the battery while controlling by the singular.
상기 고전압배터리의 목표온도는 두가지가 있는데, 첫째는 배터리 셀의 최고온도이고, 둘째는 셀간 온도편차이다.There are two target temperatures of the high voltage battery. First, the maximum temperature of the battery cell, and second, the temperature difference between the cells.
이러한 목표온도를 기반으로 이루어지는 종래의 배터리 냉각 제어 방법을 첨부한 도 를 참조로 살펴보면, 시동 온과 함께 냉각팬이 온되는 단계와, 배터리 모듈내로 유입되는 냉각공기의 온도를 측정하는 단계와, 배터리 셀간의 온도 편차 및 배터리 셀중 최고온도를 측정하는 단계와, 냉각공기의 온도가 정상범위이면 일단 냉각팬을 오프시키는 단계와, 상기 배터리 셀간의 온도 편차 및 배터리 셀중 최고온도가 냉각을 위한 범위내인지 판정하여 냉각을 위한 범위이면 냉각팬이 온되는 단계로 이루어진다.Referring to the accompanying drawings of a conventional battery cooling control method based on such a target temperature, the step of turning on the cooling fan with the start-up, measuring the temperature of the cooling air flowing into the battery module, and the battery Measuring the temperature deviation between the cells and the highest temperature of the battery cells, turning off the cooling fan once the temperature of the cooling air is in the normal range, and whether the temperature deviation between the battery cells and the maximum temperature of the battery cells are within the range for cooling If it is determined and the range for cooling, the cooling fan is turned on.
이렇게 목표온도(배터리 셀간의 온도 편차 및 배터리 셀중 최고온도)가 냉각을 위한 범위내로 유지되지 않고 열화되는 경우에는 하이브리드 차량의 주제어기인 HCU(HYBRID CONTROL UNIT)에서 최적화 주행을 위한 제어를 할 수 없고, 배터리의 내구수명에 막대한 지장을 초래하게 되는 바, 이는 배터리는 정해진 균일온도 및 적당한 온도 범위내에서 충방전이 이루어져야 배터리 셀의 수명이 오래가기 때문이 다.If the target temperature (temperature variation between battery cells and the highest temperature among the battery cells) is deteriorated without being maintained within the range for cooling, it is impossible to control for optimal driving in the hybrid controller unit (HCU), which is the main controller of the hybrid vehicle. This leads to enormous disruption to the battery's endurance life, since the battery has to be charged and discharged within a specified uniform temperature and an appropriate temperature range to prolong the life of the battery cell.
상기 고전압배터리의 열화 원인은 충방전을 하면서 발생하는 내부적 쇼트 및 부식, 전해액 변질, 내부 석출 등이 있다.The deterioration of the high voltage battery may include internal short and corrosion, electrolyte deterioration, internal precipitation, and the like, generated during charging and discharging.
상기 고전압배터리의 발열량은 저항과 전류의 제곱에 비례한다.The amount of heat generated by the high voltage battery is proportional to the square of the resistance and the current.
따라서, 상기 고전압배터리가 충방전될 때, 즉 하이브리드 기능이 작동을 하면, 배터리에 열이 발생되기 시작하는데, 이때 발열을 식히기 위해서 냉각시스템이 가동된다.Therefore, when the high-voltage battery is charged and discharged, that is, when the hybrid function is activated, heat is generated in the battery, at which time the cooling system is operated to cool down the heat.
상기 고전압배터리가 열화될수록 배터리의 저항은 증가하게 되고, BOL기준으로 종래의 배터리 냉각시스템에서는 고전압배터리의 최고 파워 사용조건에서의 냉각 풍량만 세팅해둠에 따라, 고전압배터리가 열화되었을 때 그 세팅 풍량이 나오지 않는 현상이 발생되고, 결과적으로 배터리 보호 모드가 작동을 하여 모터쪽으로 가는 파워가 제한되거나 배터리의 충전이 제한되는 현상이 발생하는 문제점이 있다.As the high voltage battery is deteriorated, the resistance of the battery increases, and in the conventional battery cooling system, only the cooling air flow rate is set at the maximum power use condition of the high voltage battery. There is a problem that does not come out, and as a result, the battery protection mode is activated to limit the power to the motor or to limit the charging of the battery.
참고로, 상기 BOL(Beginning of Life)은 고전압배터리의 초기성능을 말하고, 하기의 EOL(End of Life)은 고전압배터리가의 열화가 진행되어 더 이상 작동이 불가능하다고 판단되는 성능을 말한다.For reference, the beginning of life (BOL) refers to an initial performance of a high voltage battery, and the end of life (EOL) below refers to a performance that is determined to be impossible to operate due to deterioration of a high voltage battery.
따라서, 고전압배터리를 오래 사용함에 따라, 하이브리드 파워 성능이 떨어지는 현상이 발생하게 된다.Therefore, as the high voltage battery is used for a long time, a phenomenon in which hybrid power performance is degraded occurs.
이에, 고전압배터리의 냉각을 위한 적당한 풍량조건을 찾아서 적절히 제어해 줌으로써, 파워제한과 충전제한을 회피할 수 있는 냉각 제어조건을 EOL을 고려하여 설계를 해야 한다.Therefore, by finding the proper air flow conditions for cooling the high-voltage battery, and appropriately controlled, the cooling control conditions that can avoid the power limitation and charging limitation should be designed in consideration of EOL.
본 발명은 상기와 같은 문제점을 감안하여 안출한 것으로서, 배터리의 보증수명을 배터리의 내구수명이 종료되는 시점인 EOL을 기준으로 하여 배터리의 열화정도와 발열량을 측정하고, 배터리의 기준전압상태에서의 저항을 지속적으로 측정하여, 그 저항 측정치가 기존의 BOL기준의 배터리 저항에 비해서 어느 정도까지 증가하게 되면 풍량 단계를 보다 상향 조절함으로써, 배터리 발열량에 따른 냉각이 용이하게 이루어지면서도 배터리의 파워제한을 배터리의 내구수명까지 연장할 수 있도록 한 하이브리드 차량의 고전압배터리 냉각 제어 방법을 제공하는데 그 목적이 있다.The present invention has been made in view of the above problems, and the degree of deterioration and calorific value of a battery is measured on the basis of the EOL, which is the end point of the battery's endurance life. When the resistance is continuously measured and the resistance measurement is increased to a certain degree compared to the battery resistance based on the conventional BOL, the air flow level is further adjusted, so that the power limit of the battery can be easily cooled according to the heating value of the battery. An object of the present invention is to provide a method of controlling a high voltage battery cooling of a hybrid vehicle, which can extend the battery's endurance life.
상기한 목적을 달성하기 위한 본 발명은 시동 온과 함께 냉각팬이 온되는 단계와; 고전압배터리의 기준전압상태에서의 저항을 측정하는 단계와; 고전압배터리 모듈내로 유입되는 냉각공기의 온도를 측정하는 단계와; 고전압배터리 셀간의 온도 편차 및 여러 셀중 최고온도를 측정하는 단계와; 상기 냉각공기의 온도가 정상범위이면 일단 냉각팬을 오프시키는 단계와; 상기 고전압배터리 셀간의 온도 편차 및 여러 셀중 최고온도가 냉각을 위한 범위내인지 판정하여 냉각을 위한 범위이면 냉각팬이 온되되, 상기 저항 측정값에 따라 냉각팬 단수가 조절되는 단계; 를 포함 하는 것을 특징으로 하는 하이브리드 차량의 고전압배터리 냉각 제어 방법을 제공한다.The present invention for achieving the above object is a step in which the cooling fan is turned on with the startup on; Measuring a resistance in a reference voltage state of the high voltage battery; Measuring a temperature of cooling air flowing into the high voltage battery module; Measuring the temperature deviation between the high voltage battery cells and the highest temperature of the various cells; Turning off the cooling fan once the temperature of the cooling air is in a normal range; Determining whether a temperature deviation between the high voltage battery cells and a maximum temperature of several cells are within a range for cooling, and turning on a cooling fan if the range is for cooling, and controlling the number of cooling fan stages according to the resistance measurement value; It provides a high voltage battery cooling control method of a hybrid vehicle comprising a.
바람직한 구현예로서, 상기 고전압배터리의 보증수명을 배터리의 내구수명이 종료되는 시점인 EOL을 기준으로 정한 것을 특징으로 한다.In a preferred embodiment, the lifespan of the high voltage battery is determined based on the EOL, which is the end point of the battery's endurance life.
더욱 바람직한 구현예로서, 상기 저항을 측정하는 단계에서 상기 고전압배터리의 지속적인 사용에 따라 내구수명이 EOL 시점으로 가면서 증가하는 저항과, 배터리 열화에 따른 저항이 함께 측정되는 것을 특징으로 한다.In a more preferred embodiment, in the step of measuring the resistance, the resistance which increases as the endurance life goes to the EOL point with the continuous use of the high voltage battery, and the resistance due to battery degradation is measured together.
특히, 상기 저항 측정값이 증가함에 따라, 냉각팬의 단수가 상향 조절되는 것을 특징으로 한다.In particular, as the resistance measurement value increases, the number of stages of the cooling fan is adjusted upward.
상기한 과제 해결 수단을 통하여, 본 발명은 다음과 같은 효과를 제공할 수 있다.Through the above problem solving means, the present invention can provide the following effects.
본 발명에 따르면, 배터리의 보증수명을 EOL 기준으로 설정한 후, 배터리가 열화된 정도를 파악하여 배터리가 필요한 냉각 풍량을 정확히 제공함으로써, 냉각팬이 사용하는 에너지를 최소화하면서 하이브리드 파워를 최대한 활용할 수 있는 장점을 제공한다.According to the present invention, after setting the warranty life of the battery based on the EOL standard, by grasping the degree of deterioration of the battery to accurately provide the amount of cooling air required by the battery, it is possible to maximize the hybrid power while minimizing the energy used by the cooling fan. That provides the benefits.
즉, 고전압배터리의 기준전압상태에서의 저항을 지속적으로 측정하여, 그 저항 측정치가 BOL기준의 저항에 비해서 어느 정도까지 증가하게 되면 풍량 단계를 보다 상향 조절함으로써, 배터리 발열량에 따른 냉각이 용이하게 이루어지면서도 배터리의 파워제한을 배터리의 내구수명까지 연장할 수 있다.In other words, if the resistance value of the high voltage battery is continuously measured, and the resistance measurement is increased to a certain degree compared to the resistance of the BOL standard, the air volume step is adjusted upward, so that the cooling according to the heating value of the battery is made easier. The battery's power limit can be extended to the battery's endurance life.
이하, 본 발명의 바람직한 실시예를 첨부도면을 참조로 상세하게 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
첨부한 도 1은 본 발명에 따른 하이브리드 차량의 고전압배터리 냉각 제어 방법을 설명하는 순서도이다.1 is a flowchart illustrating a high voltage battery cooling control method of a hybrid vehicle according to the present invention.
상기 고전압배터리의 보증수명을 배터리의 내구수명이 종료되는 시점인 EOL을 기준으로 정하여, 고전압배터리의 열화정도 및 저항값을 측정하고, 그 측정값을 기반으로 고전압배터리의 냉각을 위한 냉각팬 제어가 이루어지도록 한 점에 주안점이 있다.The warranty life of the high voltage battery is determined based on the EOL, which is the end point of the endurance life of the battery, and the degree of deterioration and resistance of the high voltage battery is measured, and a cooling fan control for cooling the high voltage battery is performed based on the measured value. The point is to make it happen.
먼저, 시동 온과 함께 냉각팬이 온되면, 고전압배터리의 기준전압상태에서의 저항을 측정하는 단계와, 고전압배터리 모듈내로 유입되는 냉각공기의 온도를 측정하는 단계와, 고전압배터리 셀간의 온도 편차 및 여러 셀의 온도중 최고온도를 측정하는 단계가 연속적으로 진행된다.First, when the cooling fan is turned on with the start-up, measuring the resistance at the reference voltage of the high voltage battery, measuring the temperature of the cooling air flowing into the high voltage battery module, temperature deviation between the high voltage battery cells, The step of measuring the highest temperature among the temperatures of several cells proceeds continuously.
상기 고전압배터리의 기준전압상태에서의 저항을 측정하는 단계에서, 상기 고전압배터리의 지속적인 사용에 따라 배터리 내구수명이 EOL 시점으로 가면서 증가하는 저항과, 배터리 열화에 따른 저항이 BMS에 의하여 함께 측정된다.In the step of measuring the resistance in the reference voltage state of the high voltage battery, the resistance of the battery deterioration increases with the endurance of the high voltage battery toward the EOL point as the continuous use of the high voltage battery, and the resistance due to battery degradation are measured together by the BMS.
이때, 배터리 내구수명이 EOL 시점으로 갈수록 증가하는 저항은 미세하며, 대부분의 저항 측정값은 배터리 열화에 따른 저항이 된다.At this time, the resistance that increases as the endurance of the battery toward the EOL is minute, and most of the resistance measurement values become resistance due to battery deterioration.
상기 고전압배터리의 열화에 따라 배터리의 저항값은 증가하는데, 그 경향은 배터리의 특성에 따라 다르게 나타날 수 있지만, 첨부한 도 4에 도시된 그래프에 나타낸 바와 같이 배터리의 저항 특성은 증가하는 경향을 보이게 된다.As the high voltage battery deteriorates, the resistance value of the battery increases, but the tendency may be different depending on the characteristics of the battery, but as shown in the attached graph shown in FIG. 4, the resistance characteristic of the battery tends to increase. do.
이때, 배터리 저항은 시험으로 측정하여 맵데이타화시킬 수 있고, 배터리의 보증 수명도 여러번 시험으로 측정되어 급격히 열화되는 전인 EOL 기준으로 배터리의 보증수명도 정해질 수 있다.In this case, the battery resistance can be measured and map data, and the warranty life of the battery can also be determined on the basis of the EOL, which is measured before and after a rapid deterioration of the battery's warranty life.
상기 배터리의 증가되는 저항값은 아래의 발열량을 나타내는 수학식1에 기재된 바와 같이 저항과 선형적으로 배터리의 발열량을 증가시키게 된다.The increasing resistance value of the battery increases the heating value of the battery linearly with the resistance as described in Equation 1, which represents the heating value below.
위의 수학식1에서, Q는 발열량, R은 배터리 저항, I는 전류를 나타낸다.In Equation 1 above, Q is a heating value, R is a battery resistance, and I is a current.
다음으로, 배터리 셀이 집적되어 있는 고전압배터리 모듈의 인렛으로 유입되는 냉각공기의 온도를 측정한 결과, 상기 냉각공기의 온도가 정상범위이면 일단 냉각팬을 오프시킨다.Next, as a result of measuring the temperature of the cooling air flowing into the inlet of the high voltage battery module in which the battery cells are integrated, the cooling fan is turned off once the temperature of the cooling air is in the normal range.
이어서, 상기 고전압배터리 셀간의 온도 편차 및 셀의 최고온도가 냉각을 위한 범위내인지 판정하여 냉각을 위한 범위이면 냉각팬을 온시키되, 상기 배터리 저항값에 따라 냉각팬의 단수 조절이 조절된다.Subsequently, it is determined whether the temperature deviation between the high voltage battery cells and the maximum temperature of the cells are within the range for cooling, and the cooling fan is turned on when the cooling fan is in the range for cooling, and the number of stages of the cooling fan is adjusted according to the battery resistance value.
특히, 상기 고전압배터리의 열화에 따른 저항 측정값이 증가함에 따라, 냉각팬의 단수가 상향 조절된다.In particular, as the resistance measurement value of the high voltage battery increases, the number of stages of the cooling fan is adjusted upward.
이때, 고전압배터리의 초기 저항치 대비 저항이 증가하는 부분을 아래의 수학식 2를 이용하여 비율로 환산하여 각 고전압배터리의 냉각을 위한 필요 풍량을 단계별로 산정하고, 이 산정된 데이터를 BMS에 맵핑데이터로 저장시킨다.At this time, by converting the portion where the resistance increases to the initial resistance value of the high voltage battery by the ratio using Equation 2 below, the required air volume for cooling each high voltage battery is calculated step by step, and the calculated data is mapped to the BMS. Save it as
위의 수학식 2에서, rate는 저항증가비(>1), R은 열화된 저항값, Ri는 초기 저항값을 나타낸다.In Equation 2 above, rate represents a resistance increase ratio (> 1), R represents a degraded resistance value, and Ri represents an initial resistance value.
따라서, 고전압배터리의 열화에 따라 배터리의 저항값을 측정하고, 그 저항값에 따라 배터리의 냉각을 위한 냉각팬의 풍량을 다르게 제어함으로써, 배터리의 파워제한을 막아 배터리 성능이 내구연한까지 사용 가능함을 유도할 수 있다.Therefore, by measuring the resistance value of the battery according to the deterioration of the high-voltage battery and by controlling the air volume of the cooling fan for cooling the battery according to the resistance value, it is possible to prevent the power limit of the battery can be used until the endurance of the battery performance Can be induced.
