The internal cooling branch 3 passes through the evaporator 31. To provide cooling power for the space in the passenger compartment, the battery cooling branch 401 provides cooling power for battery cooling through a heat exchanger 411, and the battery cooling branch 402 provides cooling power for battery cooling through a heat exchanger 412. When the temperature inside the car is too high, the cooling function in the car is started, and the flow direction of the medium is: compressor 1-condenser 2-car cooling branch 3-compressor 1. When the temperature of the first battery 61 is too high, the battery cooling function is activated, and the flow direction of the medium in the first pipe and the second pipe is: compressor 1-condenser 2-battery cooling branch 401-compressor 1 and battery cooling Branch 401—battery temperature adjustment module 501—first battery 61—battery temperature adjustment module 501—battery cooling branch 401. Similarly, when the temperature of the second battery 62 is too high, the battery cooling function is activated, and the flow direction of the medium in the first pipe and the second pipe is: compressor 1-condenser 2-battery cooling branch 402-compressor 1 And battery cooling branch 402—battery temperature adjustment module 502—second battery 62—battery temperature adjustment module 502—battery cooling branch 402. Therefore, the temperature of the vehicle battery can be adjusted when the temperature of the vehicle battery is too high or too low, so that the temperature of the vehicle battery is maintained in a preset range, which avoids the situation that the performance of the vehicle battery is affected by the temperature. If the requirements are met, the temperature inside the car can meet the demand.
進一步地,根據本發明的一實施例,如第3圖所示,每一電池溫度調節模組包括:加熱器、幫浦、第一溫度感測器、介質容器、第二溫度感測器和流速感測器,其中,加熱器與控制器連接,用於加熱換熱流路中的介質,幫浦用於使換熱流路中的介質流動,第一溫度感測器用於檢測流入電池的介質的入口溫度,介質容器用於儲存以及向換熱流路提供介質,第二溫度感測器用於檢測流出電池的介質的出口溫度,流速感測器用於檢測換熱流路中的介質的流速。其中,加熱器可以為PTC(Positive Temperature Coefficient,正的溫度係數,泛指正溫度係數很大的半導體材料或元裝置)加熱器。Further, according to an embodiment of the present invention, as shown in FIG. 3, each battery temperature adjustment module includes: a heater, a pump, a first temperature sensor, a medium container, a second temperature sensor, and A flow velocity sensor, wherein the heater is connected to the controller for heating the medium in the heat exchange flow path, the pump is used for flowing the medium in the heat exchange flow path, and the first temperature sensor is used for detecting the medium flowing into the battery. At the inlet temperature, the medium container is used to store and provide the medium to the heat exchange flow path, the second temperature sensor is used to detect the outlet temperature of the medium flowing out of the battery, and the flow rate sensor is used to detect the flow rate of the medium in the heat exchange flow path. The heater may be a PTC (Positive Temperature Coefficient, generally referred to as a semiconductor material or a device having a large positive temperature coefficient) heater.
在本發明的實施例中,如第3圖所示,上述的系統還可包括與電池連接的電池狀態檢測模組,電池狀態檢測模組用於檢測電池的電流。例如,電池狀態檢測模組可以為電流霍爾感測器,電池狀態檢測模組611用於檢測第一電池61的電流,電池狀態檢測模組621用於檢測第二電池62的電流。In the embodiment of the present invention, as shown in FIG. 3, the above-mentioned system may further include a battery state detection module connected to the battery, and the battery state detection module is configured to detect a battery current. For example, the battery state detection module may be a current hall sensor, the battery state detection module 611 is used to detect the current of the first battery 61, and the battery state detection module 621 is used to detect the current of the second battery 62.
具體地,以電池冷卻支路401為例。電池冷卻支路401主要通過換熱器411(如板式換熱器)為第一電池61提供製冷功率。其中,如第3圖所示,電池冷卻支路401還可包括:第二膨脹閥421和第二電子閥431。第二電子閥431用於控制電池冷卻支路401的開通和關閉,第二膨脹閥421用於控制電池冷卻支路401的冷媒流量。Specifically, the battery cooling branch 401 is taken as an example. The battery cooling branch 401 mainly provides cooling power to the first battery 61 through a heat exchanger 411 (such as a plate heat exchanger). As shown in FIG. 3, the battery cooling branch 401 may further include a second expansion valve 421 and a second electronic valve 431. The second electronic valve 431 is used to control the opening and closing of the battery cooling branch 401, and the second expansion valve 421 is used to control the refrigerant flow rate of the battery cooling branch 401.
如第3圖所示,換熱器411可包括第一管道和第二管道,第二管道與電池溫度調節模組501相連,第一管道與壓縮機1相連通,其中,第一管道與第二管道相互獨立的臨近設置。在本發明的實施例中,換熱器411的實體位置可以位於車載空調壓縮機1所在的迴路,便於車載空調出廠調試,並且使車載空調可以單獨供貨和組裝,同時,車載空調在安裝過程中只需要加注一次介質(製冷劑)。換熱器411的實體位置也可以位於第一電池61所在的迴路,換熱器411的實體位置也可以獨立於車載空調壓縮機1所在的迴路和第一電池61所在的迴路設置。As shown in FIG. 3, the heat exchanger 411 may include a first pipe and a second pipe, the second pipe is connected to the battery temperature adjustment module 501, and the first pipe is connected to the compressor 1, wherein the first pipe is connected to the first pipe The two pipes are set up independently of each other. In the embodiment of the present invention, the physical location of the heat exchanger 411 may be located in the circuit where the vehicle-mounted air-conditioning compressor 1 is located, which facilitates the factory-adjustment of the vehicle-mounted air conditioner, and enables the vehicle-mounted air conditioner to be separately supplied and assembled. Only need to fill the medium (refrigerant) once. The physical location of the heat exchanger 411 may also be located on the circuit where the first battery 61 is located, and the physical location of the heat exchanger 411 may also be provided independently of the circuit where the vehicle-mounted air-conditioning compressor 1 is located and the circuit where the first battery 61 is located.
另外,如果換熱器411安裝在電池溫度調節模組501內,則車載空調的冷媒迴路不完全密封,所以需要先關閉第二電子閥431,然後加注冷媒,待到安裝在車上後,再與電池溫度調節模組501對接,打開第二電子膨脹閥431,再次抽真空加注冷媒後,即可進行正常工作。In addition, if the heat exchanger 411 is installed in the battery temperature adjustment module 501, the refrigerant circuit of the vehicle air conditioner is not completely sealed, so it is necessary to close the second electronic valve 431 first, and then fill the refrigerant. After the refrigerant is installed in the vehicle, After it is docked with the battery temperature adjustment module 501, the second electronic expansion valve 431 is opened and the vacuum is filled again to fill the refrigerant, and the normal work can be performed.
可以理解的是,電池冷卻支路401中也可以不設置換熱器411,當沒有換熱器411時,電池冷卻支路401內流的就是冷媒。當設置換熱器411時,電池冷卻支路401的第一管道中流的是冷媒,第二管道中流的是介質,車內冷卻支路3中流的是冷媒。It can be understood that the heat exchanger 411 may not be provided in the battery cooling branch 401. When there is no heat exchanger 411, the refrigerant flows in the battery cooling branch 401. When the heat exchanger 411 is provided, the refrigerant flows in the first pipe of the battery cooling branch 401, the medium flows in the second pipe, and the refrigerant flows in the cooling branch 3 in the vehicle.
需要說明的是,電池冷卻支路402和電池冷卻支路401相同,這裡不再詳述。It should be noted that the battery cooling branch 402 and the battery cooling branch 401 are the same, and will not be described in detail here.

The first temperature sensor 551 and the second temperature sensor 561 are respectively located at the water inlet and the outlet of the first battery 61. At the water inlet, it is used to transmit the temperature of the inlet and outlet that are detected in real time to the battery thermal management controller, so that the battery thermal management controller calculates the temperature difference between the water inlet and the water outlet. At the same time, the flow rate sensor 571 detects the The flow velocity information of the medium in the pipeline of a battery 61 loop is transmitted to the battery thermal management controller so that the battery thermal management controller can estimate the actual flow information of the current medium.

It should be understood that the medium flows into the interior of the first battery 61 from the water inlet of the flow path, and flows out of the water outlet of the flow path, thereby realizing the heat exchange between the first battery and the medium.
另外,電池熱管理控制器可通過CAN通訊控制加熱器531和加熱器532工作和調整加熱器的加熱功率,仍以第一電池61為例,當加熱器531接收到電池熱管理控制器發送的電池加熱功能啟動資訊後,啟動工作,電池熱管理控制器即時發送電池加熱功率需求,加熱器531根據加熱功率需求調整輸出功率。同時電池熱管理控制器還可通過CAN通訊控制幫浦的工作狀態,從而控制電池介質的流速和介質的流向,當接收到電池熱管理控制器發送的幫浦511啟動資訊後,開始工作,並根據電池熱管理控制器發送的流量資訊調整轉速和流量。In addition, the battery thermal management controller can control the operation of the heater 531 and the heater 532 and adjust the heating power of the heater through CAN communication.

具體地,車輛通電後,電池管理控制器判斷車輛是否需要進行溫度調節,如果判斷車輛需要溫度調節,例如,第一電池61的溫度過高,則通過CAN通訊向車載空調控制器發送開啟溫度調節功能的資訊,車載空調控制器開啟溫度調節功能後發送熱交換資訊給電池熱管理控制器,同時車載控制器控制第二電子閥431開啟,電池熱管理控制器控制幫浦511以默認轉速(如低轉速)開始工作。Specifically, after the vehicle is powered on, the battery management controller determines whether the vehicle needs temperature adjustment. If it is determined that the vehicle needs temperature adjustment, for example, the temperature of the first battery 61 is too high, it sends an on-temperature adjustment to the vehicle air-conditioning controller through CAN communication. Function information. After the vehicle air-conditioning controller turns on the temperature adjustment function, it sends heat exchange information to the battery thermal management controller. At the same time, the vehicle controller controls the second electronic valve 431 to open. The battery thermal management controller controls the pump 511 at the default speed (such as (Low speed).
同時,電池管理控制器獲取第一電池61的初始溫度(即當前溫度)、目標溫度和從初始溫度達到目標溫度的目標時間t,其中,目標溫度和目標時間t可以根據實際情況進行預設,並根據上述公式(1)計算出電池的第一溫度調節需求功率。電池管理控制器還獲取第一電池61在預設時間內的平均電流I,並根據公式(2)計算電池的第二溫度調節需求功率。然後,電池管理控制器根據第一電池61的第一溫度調節需求功率和第二溫度調節需求功率計算溫度調節需求功率P1(即將第一電池61的溫度在目標時間內調節至目標溫度的需求功率),其中,當對第一電池61進行冷卻時,P1=ΔT1 *C*M/t+I2 *R,當對第一電池61進行加熱時,P1=ΔT1 *C*M/t-I2 *R。At the same time, the battery management controller obtains the initial temperature (ie, the current temperature), the target temperature, and the target time t of the first battery 61 reaching the target temperature from the initial temperature. The target temperature and the target time t can be preset according to actual conditions. The first temperature adjustment required power of the battery is calculated according to the above formula (1). The battery management controller also obtains the average current I of the first battery 61 within a preset time, and calculates the second temperature adjustment required power of the battery according to formula (2). Then, the battery management controller calculates the temperature adjustment required power P1 according to the first temperature adjustment required power and the second temperature adjustment required power of the first battery 61 (that is, the temperature of the first battery 61 is adjusted to the target temperature required power within the target time). ), Where the first battery 61 is cooled, P1 = ΔT 1 * C * M / t + I 2 * R, and when the first battery 61 is heated, P1 = ΔT 1 * C * M / tI 2 * R.
並且,電池熱管理控制器獲取第一溫度感測器551和第二溫度感測器561檢測溫度資訊,並獲取流速感測器571檢測的流速資訊,根據上述公式(3)計算出第一電池61的溫度調節實際功率P2。In addition, the battery thermal management controller acquires temperature information detected by the first temperature sensor 551 and the second temperature sensor 561, and acquires flow velocity information detected by the flow velocity sensor 571, and calculates the first battery according to the above formula (3). The temperature of 61 regulates the actual power P2.
最後,車載空調控制器根據第一電池61的溫度調節需求功率P1、溫度調節實際功率P2控制壓縮機的輸出功率及第二膨脹閥421的開度,可選擇地,電池熱管理控制器調節幫浦511的轉速。如,若溫度調節需求功率P1大於溫度調節實際功率P2時,則根據溫度調節需求功率P1和溫度調節實際功率P2的差值,增加壓縮機的功率及增大第二膨脹閥421的開度,可選擇地增加幫浦511的轉速;若溫度調節需求功率P1小於溫度調節實際功率P2時,則根據溫度調節需求功率P1和溫度調節實際功率P2的差值,減小壓縮機的功率及減小第二膨脹閥421的開度,可選擇地減小幫浦511的轉速。Finally, the vehicle air-conditioning controller controls the output power of the compressor and the opening degree of the second expansion valve 421 according to the temperature-adjusted demand power P1 of the first battery 61 and the actual temperature-adjusted power P2. Optionally, the battery thermal management controller adjusts the help Speed of Pu 511. For example, if the temperature adjustment required power P1 is greater than the temperature adjustment actual power P2, according to the difference between the temperature adjustment required power P1 and the temperature adjustment actual power P2, the power of the compressor is increased and the opening degree of the second expansion valve 421 is increased. Optionally, increase the speed of pump 511; if the temperature adjustment required power P1 is less than the temperature adjustment actual power P2, then the difference between the temperature adjustment required power P1 and the temperature adjustment actual power P2 is used to reduce the power of the compressor and reduce The opening degree of the second expansion valve 421 can selectively reduce the rotation speed of the pump 511.
舉例說明,由上述實施例可知,溫度調節需求功率P1由兩部分組成,當第一電池61需要冷卻時,假設第一電池61初始溫度為45℃,目標溫度為35℃,則電池從45℃下降到35℃需要散發的熱量是固定,通過上述公式(1)即ΔT1 *C*M/t直接計算可以獲得,即第一溫度調節需求功率。同時,第一電池61在冷卻過程中,存在放電和充電過程,此過程會產生熱量,由於第一電池61的放電或者是充電電流是變化的,這部分的熱量也可以通過檢測電池的平均電流I直接獲得,通過上述公式(2)即I2 *R,直接計算出當前第一電池61的發熱功率,即第二溫度調節需求功率。本發明的冷卻完成時間是基於目標時間t設定的(t可以根據使用者需求或者是車輛實際設計情況改變)。在確定了冷卻完成所需要的目標時間t後,就可以預估出當前第一電池61冷卻需要的溫度調節需求功率P1,P1=ΔT1 *C*M/t+I2 *R。而如果是加熱功能啟動,則溫度調節需求功率P1=ΔT1 *C*M/t-I2 *R,即在第一電池61在加熱過程中,第一電池61的放電或者充電電流越大,所需要的加熱功率即溫度調節需求功率P1越小。For example, according to the foregoing embodiment, it can be known that the power demand for temperature adjustment P1 is composed of two parts. When the first battery 61 needs to be cooled, assuming that the initial temperature of the first battery 61 is 45 ° C and the target temperature is 35 ° C, the battery is from 45 ° C. The heat that needs to be lowered to 35 ° C is fixed. It can be obtained by directly calculating ΔT 1 * C * M / t in the above formula (1), that is, the first temperature adjustment required power. At the same time, during the cooling process of the first battery 61, there is a discharge and charging process, which generates heat. Since the discharge or charging current of the first battery 61 changes, this part of the heat can also be detected by detecting the average current of the battery. I is directly obtained, and through the above formula (2), that is, I 2 * R, directly calculates the current heating power of the first battery 61, that is, the second temperature adjustment required power. The cooling completion time of the present invention is set based on the target time t (t can be changed according to user needs or the actual design situation of the vehicle). After the target time t required to complete the cooling is determined, the current required power P1 for temperature adjustment required for cooling of the first battery 61 can be estimated, P1 = ΔT 1 * C * M / t + I 2 * R. And if the heating function is started, the temperature adjustment required power P1 = ΔT 1 * C * M / tI 2 * R, that is, during the heating process of the first battery 61, the larger the discharge or charging current of the first battery 61, the The smaller the required heating power, namely the temperature-adjusted power P1, is required.
下面將結合具體地實施例描述車載空調控制器如何根據根據每一電池6的溫度調節需求功率P1和溫度調節實際功率P2對電池6的溫度進行調節。根據本發明的一實施例,電池管理控制器,還用於獲取電池的溫度,在電池的溫度大於第一溫度臨界值時,溫度調節系統進入冷卻模式,以及在電池的溫度小於第二溫度臨界值時,溫度調節系統進入加熱模式,其中,第一溫度臨界值大於第二溫度臨界值。The following describes how the vehicle air-conditioning controller adjusts the temperature of the battery 6 according to the required power P1 and the temperature-adjusted actual power P2 according to the temperature of each battery 6 in combination with specific embodiments. According to an embodiment of the present invention, the battery management controller is further configured to obtain a temperature of the battery. When the temperature of the battery is greater than a first temperature threshold, the temperature adjustment system enters a cooling mode, and when the temperature of the battery is less than the second temperature threshold. The temperature adjustment system enters a heating mode, where the first temperature critical value is greater than the second temperature critical value.
具體地,仍以第一電池61為例。車輛通電後,電池管理控制器即時檢測第一電池61的溫度,並對其進行判斷。如果第一電池61的溫度高於40℃,說明此時第一電池61的溫度過高,為避免高溫對該第一電池61的性能產生影響,需要對第一電池61進行降溫處理,控制溫度調節系統進入冷卻模式,並發送電池冷卻功能啟動資訊給車載空調控制器。車載空調控制器在接收到電池冷卻功能啟動資訊後控制第二電子閥431開啟,以使介質與第一電池61進行熱交換以降低第一電池61的溫度。如第3圖所示,當溫度調節系統工作在冷卻模式時,第一電池61所在迴路中對應的第一管道和第二管道中介質的流動方向分別為:壓縮機1—冷凝器2—第二電子閥431—第二膨脹閥421—換熱器411—壓縮機1;換熱器411—加熱器531(關閉)—幫浦511—第一溫度感測器551—第一電池61—第二溫度感測器561—流速感測器571—介質容器521—換熱器411,如此迴圈,在換熱器411處換熱,實現第一電池61的降溫。Specifically, the first battery 61 is still taken as an example. After the vehicle is powered on, the battery management controller immediately detects the temperature of the first battery 61 and judges it. If the temperature of the first battery 61 is higher than 40 ° C, it means that the temperature of the first battery 61 is too high at this time. In order to avoid the high temperature affecting the performance of the first battery 61, the first battery 61 needs to be cooled to control the temperature. The regulation system enters the cooling mode and sends the battery cooling function activation information to the vehicle air-conditioning controller. The vehicle air-conditioning controller controls the second electronic valve 431 to open after receiving the battery cooling function activation information, so that the medium performs heat exchange with the first battery 61 to reduce the temperature of the first battery 61. As shown in Figure 3, when the temperature adjustment system is operating in the cooling mode, the flow directions of the medium in the first and second pipes corresponding to the circuit where the first battery 61 is located are: compressor 1-condenser 2- Two electronic valves 431—second expansion valve 421—heat exchanger 411—compressor 1; heat exchanger 411—heater 531 (closed) —pump 511—first temperature sensor 551—first battery 61— The second temperature sensor 561-the flow rate sensor 571-the medium container 521-the heat exchanger 411, and in this way, heat is exchanged at the heat exchanger 411 to achieve the temperature reduction of the first battery 61.
而如果第一電池61的溫度低於0℃,說明此時第一電池61的溫度過低,為避免低溫對第一電池61的性能產生影響,需要對第一電池61進行升溫處理,電池管理控制器控制溫度調節系統進入加熱模式,並發送電池加熱功能啟動資訊至車載空調控制器。車載空調控制器在接收到電池加熱功能啟動資訊後控制第二電子閥431關閉,同時電池熱管理控制器控制加熱器531開啟,以為溫度調節系統提供加熱功率。當溫度調節系統工作在加熱模式時,第一電池61中介質的流動方向為:換熱器411—加熱器531(開啟)—幫浦511—第一溫度感測器551—第一電池61—第二溫度感測器561—流速感測器571—介質容器521—換熱器411,如此迴圈,實現第一電池61的升溫。If the temperature of the first battery 61 is lower than 0 ° C, it means that the temperature of the first battery 61 is too low at this time. In order to prevent the low temperature from affecting the performance of the first battery 61, the temperature of the first battery 61 needs to be increased. Battery management The controller controls the temperature adjustment system to enter the heating mode, and sends the battery heating function activation information to the vehicle air-conditioning controller. The vehicle air-conditioning controller controls the second electronic valve 431 to close after receiving the battery heating function activation information, and the battery thermal management controller controls the heater 531 to turn on to provide heating power for the temperature adjustment system. When the temperature adjustment system works in the heating mode, the flow direction of the medium in the first battery 61 is: heat exchanger 411-heater 531 (on)-pump 511-first temperature sensor 551-first battery 61- The second temperature sensor 561-the flow rate sensor 571-the medium container 521-the heat exchanger 411, and in this way, the temperature of the first battery 61 is raised.
進一步地,根據本發明的一實施例,車載空調控制器在該溫度調節需求功率大於溫度調節實際功率時,獲取溫度調節需求功率和溫度調節實際功率之間的功率差,當為冷卻模式時,車載空調控制器根據功率差增加用於冷卻電池的壓縮機的功率和閥的開度中至少一者,以及在溫度調節需求功率小於或等於溫度調節實際功率時,減小/保持電池的壓縮機的功率和閥的開度中至少一者。當為加熱模式時,電池熱管理控制器根據功率差增加用於加熱電池的加熱器的功率,以及在溫度調節需求功率小於或等於溫度調節實際功率時,減小/保持加熱器的功率。Further, according to an embodiment of the present invention, when the vehicle air-conditioning controller requires the temperature adjustment required power to be greater than the actual temperature adjustment power, it obtains a power difference between the temperature adjustment required power and the temperature adjustment actual power. When the cooling mode is used, The vehicle air-conditioning controller increases at least one of the power of the compressor for cooling the battery and the opening degree of the valve according to the power difference, and reduces / maintains the compressor of the battery when the power required for temperature adjustment is less than or equal to the actual power for temperature adjustment At least one of the power and the valve opening. When in the heating mode, the battery thermal management controller increases the power of the heater for heating the battery according to the power difference, and reduces / maintains the power of the heater when the power required for temperature adjustment is less than or equal to the actual power for temperature adjustment.
具體地,仍以第一電池為例。當溫度調節系統工作在冷卻模式時,電池管理控制器獲取第一電池61的溫度調節需求功率P1,電池熱管理控制器獲取第一電池61的溫度調節實際功率P2,車載空調控制器根據溫度調節需求功率P1和溫度調節實際功率P2進行判斷。如果第一電池61的溫度調節需求功率P1大於溫度調節實際功率P2,說明如果按照當前的製冷功率或者介質流量,無法在目標時間內完成該第一電池61的降溫,所以,車載空調控制器獲取電池的溫度調節需求功率P1和溫度調節實際功率P2之間的功率差,並根據功率差增加壓縮機1的功率,或者增加電池的介質流量,即增加第二膨脹閥421的開度,以增加該電池的冷卻功率,其中,溫度調節實際功率P1與溫度調節實際功率P2的功率差越大,壓縮機1的功率和該電池的介質流量增加越多,以使該電池的溫度在預設時間t內降低至目標溫度。而如果第一電池61的溫度調節實際功率P1小於或等於溫度調節實際功率P2,車載空調控制器可以保持壓縮機1的功率不變或適當減小壓縮機1的功率,或者減少該電池的介質流量,即減小第二膨脹閥421的開度,以減少電池的冷卻功率。當第一電池61的溫度低於35℃時,則電池6冷卻完成,電池管理控制器通過CAN通訊向車載空調控制器發送關閉溫度調節功能的資訊,車載空調控制器控制第二電子閥431關閉。如果溫度調節系統進入冷卻模式較長時間後,例如1小時後,仍有第一電池61的溫度高於35℃,則車載空調控制器適當增加壓縮機1的功率,以使該電池儘快完成降溫。Specifically, the first battery is still taken as an example. When the temperature adjustment system works in the cooling mode, the battery management controller obtains the temperature adjustment required power P1 of the first battery 61, the battery thermal management controller obtains the actual temperature adjustment power P2 of the first battery 61, and the vehicle air-conditioning controller adjusts according to the temperature The required power P1 and the temperature adjustment actual power P2 are judged. If the temperature adjustment required power P1 of the first battery 61 is greater than the actual temperature adjustment power P2, it means that if the current cooling power or the medium flow rate cannot complete the temperature reduction of the first battery 61 within the target time, the vehicle air-conditioning controller obtains The power difference between the battery temperature adjustment required power P1 and the temperature adjustment actual power P2, and the power of the compressor 1 is increased according to the power difference, or the medium flow rate of the battery is increased, that is, the opening degree of the second expansion valve 421 is increased to increase The cooling power of the battery, wherein the larger the power difference between the temperature-regulated actual power P1 and the temperature-regulated actual power P2, the more the power of the compressor 1 and the medium flow rate of the battery increase, so that the temperature of the battery is at a preset time Reduce to the target temperature within t. And if the temperature-regulated actual power P1 of the first battery 61 is less than or equal to the temperature-regulated actual power P2, the vehicle-mounted air conditioning controller can keep the power of the compressor 1 unchanged or reduce the power of the compressor 1 appropriately, or reduce the medium of the battery The flow rate, that is, the opening degree of the second expansion valve 421 is reduced to reduce the cooling power of the battery. When the temperature of the first battery 61 is lower than 35 ° C, the cooling of the battery 6 is completed. The battery management controller sends information to the vehicle air-conditioning controller to turn off the temperature adjustment function through CAN communication. The vehicle air-conditioning controller controls the second electronic valve 431 to close. . If the temperature adjustment system enters the cooling mode for a long time, for example, after 1 hour, the temperature of the first battery 61 is still higher than 35 ° C, the vehicle air-conditioning controller appropriately increases the power of the compressor 1 so that the battery can cool down as soon as possible. .
當溫度調節系統工作在加熱模式時,電池熱管理控制器獲取電池的P1,電池熱管理控制器獲取電池的溫度調節實際功率P2。如果第一電池61的溫度調節需求功率P1大於溫度調節實際功率P2,說明如果按照當前的加熱功率或者介質流量,無法在目標時間內完成該第一電池61的升溫,所以,電池熱管理控制器獲取該電池的溫度調節需求功率P1和溫度調節實際功率P2之間的功率差,並根據功率差增加用於加熱第一電池61的加熱器531的功率,或者調節增加電池的介質流量,例如可以增幫浦511的轉速,以使該電池可以在目標時間內完成溫度調節。其中,溫度調節需求功率P1和溫度調節實際功率P2的差值越大,加熱器531的功率和該電池迴路的介質流量增加的越多。而如果電池的溫度調節需求功率P1小於或等於溫度調節實際功率P2,電池熱管理控制器可以適當減小加熱器531的功率,或保持加熱器531的功率不變,或者調節減少該電池迴路的介質流量,以減少電池的加熱功率。當第一電池61的溫度高於預設溫度,例如10℃時,第一電池61加熱完成,電池管理控制器通過CAN通訊向電池熱管理控制器發送關閉溫度調節功能的資訊,電池熱管理控制器控制加熱器531關閉。如果溫度調節系統進入加熱模式較長時間後,例如1小時後,仍有第一電池61的溫度低於10℃,則電池熱管理控制器再適當增加加熱器531的功率,以使第一電池61儘快完成升溫。When the temperature adjustment system works in the heating mode, the battery thermal management controller obtains P1 of the battery, and the battery thermal management controller obtains the battery's temperature adjustment actual power P2. If the temperature adjustment required power P1 of the first battery 61 is greater than the actual temperature adjustment power P2, it means that if the current heating power or the medium flow rate cannot be used to complete the temperature rise of the first battery 61 within the target time, the battery thermal management controller Obtain the power difference between the temperature adjustment required power P1 and the temperature adjustment actual power P2 of the battery, and increase the power of the heater 531 for heating the first battery 61 according to the power difference, or adjust to increase the medium flow of the battery. For example, you can Increase the speed of the pump 511 so that the battery can complete temperature adjustment within the target time. The larger the difference between the temperature adjustment required power P1 and the temperature adjustment actual power P2, the more the power of the heater 531 and the medium flow rate of the battery circuit increase. And if the battery temperature adjustment required power P1 is less than or equal to the temperature adjustment actual power P2, the battery thermal management controller can appropriately reduce the power of the heater 531, or keep the power of the heater 531 unchanged, or adjust to reduce the battery circuit's power. Media flow to reduce the heating power of the battery. When the temperature of the first battery 61 is higher than a preset temperature, for example, 10 ° C, the heating of the first battery 61 is completed. The battery management controller sends information to the battery thermal management controller to close the temperature adjustment function through CAN communication. The battery thermal management control The heater control heater 531 is turned off. If the temperature adjustment system enters the heating mode for a long time, for example, after one hour, the temperature of the first battery 61 is still lower than 10 ° C, the battery thermal management controller appropriately increases the power of the heater 531 to make the first battery 61 to complete the heating as soon as possible.
根據本發明的一實施例,在溫度調節需求功率小於或等於溫度調節實際功率時,電池熱管理控制器還用於降低/保持幫浦的轉速,在溫度調節需求功率大於溫度調節實際功率時,電池熱管理控制器還用於提高幫浦的轉速。According to an embodiment of the present invention, when the power required for temperature adjustment is less than or equal to the actual power for temperature adjustment, the battery thermal management controller is further configured to reduce / maintain the speed of the pump. When the power required for temperature adjustment is greater than the actual power for temperature adjustment, The battery thermal management controller is also used to increase the speed of the pump.
具體地,仍以第一電池61為例。當溫度調節系統進入加熱模式或者冷卻模式時,如果第一電池61的溫度調節需求功率P1小於溫度調節實際功率P2,電池熱管理控制器控制幫浦511的轉速降低,以節省電能,或者保持幫浦511的轉速不變。而如果第一電池61的溫度調節需求功率P1大於溫度調節實際功率P2,電池熱管理控制器還用於控制幫浦511的轉速提高,可以增加單位時間內流經冷卻流路橫截面積的介質品質,從而提高電池的溫度調節實際功率P2,以在目標時間t內實現溫度調節。而如果第一電池61的溫度調節需求功率P1等於於溫度調節實際功率P2,那麼控制幫浦511的轉速保持在當前轉速不變即可。Specifically, the first battery 61 is still taken as an example. When the temperature adjustment system enters the heating mode or the cooling mode, if the temperature adjustment required power P1 of the first battery 61 is less than the actual temperature adjustment power P2, the battery thermal management controller controls the rotation speed of the pump 511 to reduce power, or to maintain power The speed of Pu 511 is unchanged. If the temperature adjustment required power P1 of the first battery 61 is greater than the actual temperature adjustment power P2, the battery thermal management controller is also used to control the increase of the rotation speed of the pump 511, which can increase the medium flowing through the cross-sectional area of the cooling channel per unit time Quality, thereby improving the battery's temperature adjustment actual power P2 to achieve temperature adjustment within the target time t. And if the temperature adjustment required power P1 of the first battery 61 is equal to the temperature adjustment actual power P2, then the speed of the control pump 511 may be maintained at the current speed.
需要說明的是,上述實施例均以第一電池為例,同樣地,第二電池的溫度調節原理與第一電池的原理相同,為避免冗長,具體這裡不再贅述。It should be noted that the above embodiments all take the first battery as an example. Similarly, the temperature adjustment principle of the second battery is the same as that of the first battery. To avoid redundancy, the details are not described herein again.
在本發明的一實施例中,如第4圖所示,電池冷卻支路還可包括調節閥。In an embodiment of the present invention, as shown in FIG. 4, the battery cooling branch may further include a regulating valve.
具體地,調節製冷迴路對電池冷卻分支迴路分配的冷卻功率時,車載空調控制器先調節膨脹閥的開度,待調節完成後,車載空調控制器估算各電池冷卻分支支路的製冷功率,確定是否已經調節到位,如果電池冷卻分支支路功率還沒有達到目標值,則繼續調整膨脹閥開度。同時空調根據2個電池之間的溫度情況,通過調控制調節閥,來調節電池冷卻支路401和電池冷卻支路402的冷媒流量,從而調節第一電池61和第二電池62的冷卻功率。車載空調控制器可以根據第一電池61和第二電池62的溫度狀況,控制調節閥441和調節閥442的開度控制第一電池61和第二電池62這兩個冷卻分支支路的介質流量分配,從而達到控制動力第一電池61和第二電池62的溫度均衡。當車輛需要冷卻時,如果第一電池61的溫度比第二電池62的溫度高,則可增大調節閥441的開度,減少調節閥442的開度,當第一電池61和第二電池62的平均溫度相等時,可控制調節閥的開度相同,以保持兩個動力電池組溫度均衡。Specifically, when adjusting the cooling power allocated by the refrigeration circuit to the battery cooling branch circuit, the vehicle air-conditioning controller first adjusts the opening degree of the expansion valve. After the adjustment is completed, the vehicle air-conditioning controller estimates the cooling power of each battery cooling branch and determines Whether it has been adjusted in place, if the power of the battery cooling branch has not reached the target value, then continue to adjust the opening of the expansion valve. At the same time, the air conditioner adjusts the control valve to adjust the refrigerant flow of the battery cooling branch 401 and the battery cooling branch 402 according to the temperature between the two batteries, thereby adjusting the cooling power of the first battery 61 and the second battery 62. The vehicle air-conditioning controller may control the opening of the regulating valve 441 and the regulating valve 442 according to the temperature conditions of the first battery 61 and the second battery 62 to control the medium flow of the two cooling branch branches of the first battery 61 and the second battery 62 Distribution, so as to achieve the temperature equilibrium of the control power of the first battery 61 and the second battery 62. When the vehicle needs to be cooled, if the temperature of the first battery 61 is higher than the temperature of the second battery 62, the opening degree of the regulating valve 441 can be increased and the opening degree of the regulating valve 442 can be reduced. When the average temperature of 62 is equal, the opening degree of the controllable control valve is the same to maintain the temperature balance of the two power battery packs.
可以理解的是,如果單個壓縮機1無法滿足冷卻複數電池時所需的功率,則可設置複數壓縮機1為電池6提供冷卻功率。It can be understood that if a single compressor 1 cannot meet the power required for cooling a plurality of batteries, a plurality of compressors 1 may be set to provide cooling power for the battery 6.
根據本發明的一實施例,如第5圖所示,製冷支路為複數,其中壓縮機可以為複數,且複數壓縮機相互並聯。According to an embodiment of the present invention, as shown in FIG. 5, the refrigeration branch is plural, and the compressors may be plural, and the plural compressors are connected in parallel with each other.

在本發明的實施例中,車載空調控制器還檢測車廂內各區域的氣溫,並可根據各區域的氣溫差異,以及系統的熱管理功率需求,調節各製冷迴路對電池冷卻分支迴路的功率分配,從而平衡各區域的氣溫。In the embodiment of the present invention, the vehicle-mounted air-conditioning controller also detects the air temperature in each area of the cabin, and can adjust the power distribution of each cooling circuit to the battery cooling branch circuit according to the temperature difference in each area and the thermal management power requirement of the system. To balance the temperature in each area.
舉例而言,如第6圖所示,假設出風口1和出風口2都由製冷迴路1提供冷卻功率,出風口3和出風口4都由製冷迴路2提供冷卻功率。當電池冷卻功能啟動時,當車載空調控制器檢測到出風口1和出風口2附近的氣溫比出風口3和出風口4所在區域的氣溫高,且相差較大時,車載空調控制器可以控制第二膨脹閥421的開度減少,第一膨脹閥321的開度增大,從而使得製冷迴路1中車內冷卻分支支路301的冷卻功率增加,電池冷卻分支支路401的冷卻功率減少。同時,為了保證電池箱的冷卻功率不變,車載空調控制器還可以控制第一膨脹閥322開度減少,第二膨脹閥422開度增大,從而使得製冷迴路2中車內冷卻分支支路302的冷卻功率減少,電池冷卻分支支路402的冷卻功率增加。這樣使得車廂內各區域的氣溫可實現均衡,同時又可以滿足電池箱的製冷功率需求。For example, as shown in FIG. 6, it is assumed that both the air outlet 1 and the air outlet 2 are provided with cooling power by the refrigeration circuit 1, and the air outlet 3 and the air outlet 4 are provided with cooling power by the refrigeration circuit 2. When the battery cooling function is activated, when the vehicle air-conditioning controller detects that the temperature near the air outlet 1 and the air outlet 2 is higher than the temperature in the area where the air outlet 3 and the air outlet 4 are located, and the difference is large, the vehicle air-conditioning controller can control The opening degree of the second expansion valve 421 decreases and the opening degree of the first expansion valve 321 increases, so that the cooling power of the cooling branch branch 301 in the vehicle in the refrigeration circuit 1 increases, and the cooling power of the battery cooling branch branch 401 decreases. At the same time, in order to ensure that the cooling power of the battery box does not change, the vehicle air-conditioning controller can also control the opening degree of the first expansion valve 322 to decrease and the opening degree of the second expansion valve 422 to increase, so that the cooling branch branch in the vehicle in the refrigeration circuit 2 The cooling power of 302 decreases, and the cooling power of the battery cooling branch branch 402 increases. In this way, the temperature in each area of the cabin can be balanced, and at the same time, the cooling power requirements of the battery box can be met.
作為一具體示例,當車廂內的各出風口附近所在區域的溫度差異較大時,需要調節車內冷卻分支支路的製冷量分配,此時可通過調節第一膨脹閥321、第二膨脹閥421、第一膨脹閥322和第二膨脹閥422的開度,達到重新分配車內冷卻分支支路和電池冷卻分支支路的製冷功率分配。調節製冷迴路1和製冷迴路2對電池冷卻分支支路分配的冷卻功率時,車載空調控制器先調節膨脹閥的開度,待調節完成後,車載空調估算各電池冷卻分支支路的製冷功率,確定是否已經調節到位,如果電池冷卻分支迴路功率還沒有達到目標值,則繼續調整膨脹閥開度。同時空調根據2個電池組之間的溫度情況,通過控制調節閥,來調節電池冷卻支路401和電池冷卻支路402的冷媒流量,從而調節第一電池61和第二電池62的冷卻功率。車載空調控制器還可以根據第一電池61和第二電池62的電池溫度狀況,控制第一調節閥441、第二調節閥442、第三調節閥443和第四調節閥444的開度控制第一電池61和第二電池62這兩個冷卻分支迴路的介質流量分配,從而達到控制第一電池61和第二電池62的電池溫度均衡。當車輛需要冷卻時,如果動第一電池61的溫度比第二電池62的溫度高,則可增大第一調節閥441和第三調節閥443的開度,減少第二調節閥442和第四調節閥444的開度,當第一電池61和第二電池62的平均溫度相等時,可控制調節閥的開度相同,以保持兩個動力電池組溫度均衡。As a specific example, when the temperature difference in the area near each air outlet in the cabin is large, it is necessary to adjust the cooling capacity distribution of the cooling branch branch in the cabin. At this time, the first expansion valve 321 and the second expansion valve can be adjusted. 421. The openings of the first expansion valve 322 and the second expansion valve 422 achieve the redistribution of the cooling power distribution in the vehicle cooling branch branch and the battery cooling branch branch. When adjusting the cooling power allocated by the refrigeration circuit 1 and the refrigeration circuit 2 to the battery cooling branch branch, the vehicle air-conditioning controller first adjusts the opening degree of the expansion valve. After the adjustment is completed, the vehicle air conditioner estimates the cooling power of each battery cooling branch branch. Determine whether it has been adjusted in place. If the battery cooling branch circuit power has not reached the target value, continue to adjust the expansion valve opening. At the same time, the air conditioner adjusts the refrigerant flow of the battery cooling branch 401 and the battery cooling branch 402 by controlling the regulating valve according to the temperature between the two battery packs, thereby adjusting the cooling power of the first battery 61 and the second battery 62. The vehicle air-conditioning controller may also control the opening degrees of the first, second, and third control valves 441, 442, 443, and 444 according to the battery temperature conditions of the first and second batteries 61 and 62. The medium flow distribution of the two cooling branch circuits of the first battery 61 and the second battery 62 is distributed, so as to control the battery temperature balance of the first battery 61 and the second battery 62. When the vehicle needs to be cooled, if the temperature of the first battery 61 is higher than the temperature of the second battery 62, the openings of the first regulating valve 441 and the third regulating valve 443 can be increased, and the second regulating valve 442 and the first regulating valve 442 can be reduced. When the openings of the four regulating valves 444 are equal, when the average temperatures of the first battery 61 and the second battery 62 are equal, the openings of the regulating valves can be controlled to keep the temperature of the two power battery packs balanced.

其中,半導體換模組具有半導體發熱端和半導體冷卻端,當供電電源反接後,發熱端和冷卻端位置交換,從而控制半導體換熱模組的發熱端接入到電池溫度較低的電池水冷迴路中,冷卻端接入電池溫度較高的電池水冷迴路中。Among them, the semiconductor replacement module has a semiconductor heating end and a semiconductor cooling end. When the power supply is reversely connected, the heating end and the cooling end are exchanged, thereby controlling the heating end of the semiconductor heat exchange module to be connected to a battery with a lower battery temperature.
