[0002] Currently, a server or a vehicle controller, etc. calculates the refrigerating capacity based on parameters such as the temperature of the coolant, the specific heat capacity of the coolant, the mass flow rate of the coolant, the specific heat capacity of the battery, the internal resistance of the battery, and the entropy change coefficient of the battery. After calculating the current refrigerating capacity, the size of the refrigerating capacity is adjusted according to the battery heat load, thereby saving energy consumption.

[0003] In the above method, the calculation of the refrigerating capacity requires the configuration of a compressor temperature sensor, and the overall calculation process is relatively complex. Summary of the Invention

[0004] An embodiment of this application provides a method and related device for air conditioner control. The refrigerating capacity is calculated based on the collected compressor speed, and the operation of the compressor is controlled according to the calculated battery heat load and refrigerating capacity. The above process requires fewer parameters, is simple to obtain, and does not require the configuration of a temperature sensor, and the calculation is convenient, which can ensure that the battery temperature is within a reasonable range, achieve the effect of reducing the power consumption of the compressor, and ensure the stable and efficient operation of the system.

[0005] In a first aspect, this application provides a method for air conditioner control for a vehicle, and the method includes: determining the battery heat load according to the obtained battery discharge voltage and battery discharge current, and obtaining the refrigerating capacity of the compressor; controlling the operation of the compressor according to the battery heat load and the refrigerating capacity.

[0006] In the above process, the battery heat load and the refrigerating capacity are calculated through the battery discharge voltage, battery discharge current, and compressor parameters directly obtained from the vehicle, and the operation of the compressor is controlled according to the magnitude relationship between the battery heat load and the refrigerating capacity, so as to realize the adjustment of the size of the refrigerating capacity, thereby ensuring that the battery temperature is within a reasonable range, reducing the power consumption of the compressor, and ensuring the stable and efficient operation of the system. The parameters required for the above calculation process are simple and do not require temperature-related parameters. Therefore, it is not necessary to configure a compressor temperature sensor in the system, and all parameters can be directly obtained from the vehicle, and the overall calculation process is simple, which can make the system operate energy-efficiently.

[0007] In a possible implementation manner, the refrigerating capacity of the compressor is obtained according to the compressor operation parameters, and the compressor operation parameters include one or more of the speed of the compressor, the discharge pressure of the compressor, and the suction pressure of the compressor. Calculating the refrigerating capacity through the first speed, the first discharge pressure, and the first suction pressure is simpler than the calculation process of calculating the refrigerating capacity according to parameters such as temperature, and it is not necessary to configure a compressor temperature sensor in the system, and the parameters can be obtained more conveniently.

[0008] In a possible implementation manner, the specific process of controlling the operation of the compressor according to the battery heat load and the refrigerating capacity is as follows: calculate the difference between the battery heat load and the refrigerating capacity, and control the operation of the compressor according to the difference.

[0009] In a possible implementation manner, the specific process of controlling the operation of the compressor according to the difference between the battery heat load and the refrigerating capacity is as follows: adjust the rotation speed of the compressor according to the difference between the battery heat load and the refrigerating capacity, so as to control the operation of the compressor.

[0010] In a possible implementation manner, the compressor operation parameters include the first rotation speed of the compressor. The specific process of adjusting the rotation speed of the compressor according to the difference between the battery heat load and the refrigerating capacity is as follows: when the difference between the battery heat load and the refrigerating capacity is greater than or equal to the first threshold, adjust the rotation speed of the compressor to be greater than the first rotation speed; and / or, when the difference between the battery heat load and the refrigerating capacity is less than or equal to the second threshold, adjust the rotation speed of the compressor to be less than the first rotation speed; and / or, when the difference between the battery heat load and the refrigerating capacity is less than the first threshold and greater than the second threshold, control the rotation speed of the compressor to operate at the first rotation speed. By comparing the magnitudes of the battery heat load and the refrigerating capacity, the adjustment of the rotation speed of the compressor is realized. When the refrigerating capacity is equivalent to the battery heat load demand, the current rotation speed of the compressor is maintained to ensure the normal operation of the system; when the current refrigerating capacity cannot meet the battery heat load demand, the first rotation speed is increased to obtain the second rotation speed, so as to realize the increase of the refrigerating capacity; when the refrigerating capacity exceeds the battery heat load demand, the first rotation speed is decreased to determine the second rotation speed, thereby reducing the energy consumption of the compressor and enabling the system to operate energy-efficiently.

[0011] In a possible implementation manner, the discharge port pressure of the compressor and the suction port pressure of the compressor are determined based on the rotation speed of the compressor.

[0015] In a possible implementation, the refrigerating capacity of the compressor is obtained according to the compressor operation parameters, and the compressor operation parameters include one or more of the rotational speed of the compressor, the discharge port pressure of the compressor, and the suction pressure of the compressor. Calculating the refrigerating capacity through the first rotational speed, the first discharge port pressure, and the first suction port pressure is simpler than the calculation process of calculating the refrigerating capacity according to parameters such as temperature, and it is not necessary to configure a compressor temperature sensor in the system, so that parameters can be obtained more conveniently.

[0034] Currently, a server or a vehicle controller, etc. controls the cooling capacity according to the battery heat load. Among them, the calculation of the cooling capacity requires the following multiple parameters: the temperature of the coolant, the specific heat capacity of the coolant, the mass flow rate of the coolant, the specific heat capacity of the battery, the internal resistance of the battery, and the entropy change coefficient of the battery, etc. There are many parameters required for calculating the cooling capacity, and it is necessary to configure a temperature sensor in the vehicle air-conditioning system. Moreover, it is difficult to obtain various parameters on the vehicle, and the process of calculating the cooling capacity is relatively complex.

[0035] Therefore, the present application provides a method for air conditioner control, which calculates the cooling capacity through simple and easily obtainable data such as the compressor speed, calculates the battery heat load according to the battery discharge voltage and the battery discharge current, and adjusts the compressor speed according to the battery heat load and the cooling capacity, which can simplify the calculation of the cooling capacity, improve the calculation efficiency, and realize reducing the compressor power consumption while meeting the battery heat load requirement, and ensure the stable and efficient operation of the system.

[0036] As Figure 1 shown, Figure 1 is a schematic structural diagram of an air-conditioning system provided by an embodiment of the present application. This system is in vehicle 100. This system includes an electronic device 110 and a vehicle-mounted air-conditioning control system 120. The vehicle-mounted air-conditioning control system includes devices such as a compressor 121. Among them, the electronic device is connected to the vehicle-mounted air-conditioning control system through a controller area network (CAN) bus, etc.

[0037] In specific implementation, the electronic device can be a body control module (BMC), an electronic control unit for controlling the body electrical system, and controlling the vehicle-mounted air-conditioning control system. The electronic device is used to control the vehicle-mounted air-conditioning control system according to the instructions generated by itself, and can obtain and process the data of the vehicle-mounted air-conditioning control system and other devices.

[0038] In a possible implementation manner, the electronic device may also include other forms, and the present application does not make specific limitations on this.

[0039] In a possible implementation, when the electronic device in the vehicle has a certain computing power, the electronic device trains a computing model based on the obtained multiple sets of battery thermal load historical data to obtain a first computing model, and trains the computing model based on the obtained multiple sets of refrigeration capacity historical data to obtain a second computing model.

[0040] As Figure 2 shown, Figure 2 FIG. is a flowchart of a method for generating a computing model provided by an embodiment of the present application. This method can be applied to Figure 1 the electronic device shown above. This method includes the following multiple steps.

[0041] Step S210: Obtain battery thermal load historical data and refrigeration capacity historical data.

[0042] The electronic device obtains multiple sets of battery thermal load historical data and multiple sets of refrigeration capacity historical data. Among them, each set of battery thermal load historical data includes a historical battery thermal load, a historical battery discharge current, and a historical battery discharge voltage. Each historical battery thermal load in the historical battery thermal load corresponds to a historical battery discharge current and a historical battery discharge voltage; each set of refrigeration capacity historical data includes a historical compressor parameter and a historical refrigeration capacity. Each historical refrigeration capacity in the historical refrigeration capacity corresponds to a historical compressor parameter. A historical compressor parameter includes a historical compressor speed, a historical compressor discharge port pressure, and a historical compressor suction port pressure.

[0043] In a possible implementation, the battery thermal load historical data and the refrigeration capacity historical data may include more or fewer parameters, and the present application does not make specific limitations on this.

[0044] Step S220: Determine a first computing model according to the battery thermal load historical data.

[0045] The electronic device determines the corresponding relationship between the battery thermal load, the battery discharge voltage, and the battery discharge current according to the battery thermal load historical data, and determines the first computing model corresponding to the battery thermal load. The first computing model is used to calculate the current battery thermal load according to the obtained current battery discharge voltage and current battery discharge current during the application process. The specific formula is as follows:

[0046] Q t =X 1 *P 2 +X 2 *P+X 3

[0047] Among them, Q t represents the battery thermal load, P is the battery discharge power, which is calculated by multiplying the battery discharge voltage U and the battery discharge current I. X1 , X 2 and X 3 are calculation coefficients, obtained by fitting multiple sets of historical battery heat load data acquired above.

[0048] Step S230: Determine the second calculation model according to the historical refrigeration capacity data.

[0049] The electronic device determines the corresponding relationship between the refrigeration capacity, the compressor speed, the compressor discharge port pressure, and the compressor suction port pressure according to the historical refrigeration capacity parameters, and determines the second calculation model corresponding to the refrigeration capacity. The second calculation model is used to calculate the current refrigeration capacity of the compressor according to the currently acquired compressor operating parameters. The specific formula is as follows:

[0050] Q c = c 1 + c 2 * Ps + c 3 * Pd + c 4 * fr + c 5 * Ps 2 + c 6 * Pd 2 + c 7 * fr 2 + c 8 * Ps * Pd + c 9 * Ps * fr + c 10 * Pd * fr + c 11 * PS 3 + c 12 * Pd 3 + c 13 * fr 3 + c 14 * Ps 2 * Pd + c 15 * Ps * Pd 2 + c 15 * Ps * Pd 2 + c 16 * Ps 2 * fr + c 17 * fr 2 * Ps + c 18 * Pd 2 * fr + c 19 * fr 2 * Pd + c 20 * Ps * Pd * fr

[0051] Among them, Q c represents the refrigeration capacity, Ps is the compressor suction port pressure, Pd is the compressor discharge port pressure, fr is the compressor speed, c 1 , c 2 …c 20It is obtained by fitting multiple sets of historical cooling capacity data acquired above for calculating coefficients.

[0052] In a possible implementation manner, there may be other calculation formulas for the first calculation model and the second calculation model, and the present application does not make specific limitations thereto.

[0053] By using the historical battery heat load data and the historical cooling capacity data, the above method obtains the first calculation model and the second calculation model, and can subsequently calculate the battery heat load and the cooling capacity according to parameters that can be simply and conveniently obtained, simplifying the calculation process, improving the calculation efficiency, and the parameters required for the first calculation model and the second calculation model to calculate the battery heat load and the cooling capacity can be simply obtained from the whole vehicle.

[0054] In a possible implementation manner, the above method consumes a large amount of computing resources on the electronic device side. Therefore, the above method can be applied to a server connected to the vehicle through a network. When the server calculates the first calculation model and the second calculation model, the server sends the first calculation model and the second calculation model to the electronic device so that the electronic device calculates the battery thermal effect and the cooling capacity according to the first calculation model and the second calculation model. The server can also calculate the battery thermal effect and the cooling capacity according to the parameters obtained from the vehicle, and the present application does not make specific limitations thereto.

[0055] This application embodiment takes the electronic device calculating the battery thermal effect and the cooling capacity according to the first calculation model and the second calculation model to control the vehicle air conditioning control system as an example for illustration.

[0056] As Figure 3 shown, Figure 3 is a flowchart of an air conditioning control method provided by this application embodiment. The method includes the following multiple steps.

[0057] Step S310: Determine the battery heat load according to the acquired battery discharge voltage and battery discharge current.

[0058] The electronic device acquires the sampled battery discharge voltage and battery discharge current, and calculates the battery heat load according to the battery discharge voltage, the battery discharge current, and the pre-generated first calculation model.

[0059] Step S320: Acquire the cooling capacity of the compressor.

[0060] The electronic device obtains the compressor operating parameters obtained by sampling, and determines the cooling capacity of the air conditioner according to the compressor operating parameters and the generated second calculation model. The compressor operating parameters include one or more of the rotational speed of the compressor, the discharge pressure of the compressor, and the suction pressure of the compressor. This application does not make specific limitations on this. The compressor parameters obtained by the electronic device correspond to the same time point as the battery discharge voltage and battery discharge current obtained in step S310.

[0061] In the above process, the parameters required for calculation can be directly sampled from the vehicle, and the types of required parameters are few. Combining with the pre-generated calculation model, the battery heat load and cooling capacity corresponding to the sampled parameters can be determined, which can reduce the difficulty of data acquisition, simplify the calculation process, and do not require obtaining parameters such as the temperature of the compressor, and do not require configuring a compressor temperature sensor, which can simplify the system complexity.

[0062] Step S330: Control the operation of the compressor according to the battery heat load and the cooling capacity.

[0063] The electronic device adjusts the rotational speed of the compressor according to the difference between the battery heat load and the cooling capacity, thereby controlling the operation of the compressor.

[0064] The compressor operating parameters include the first rotational speed of the compressor. The electronic device calculates the difference between the battery heat load and the cooling capacity, compares the difference with the first rotational speed, and determines how to adjust the rotational speed of the compressor, so as to meet the battery heat load demand under the condition of lower compressor power consumption and better control the compressor.

[0065] In a possible implementation manner, when the difference between the battery heat load and the cooling capacity is greater than or equal to the first threshold, it is determined that the cooling capacity provided by the compressor at this time cannot meet the battery heat load demand, and the rotational speed of the compressor is adjusted to be greater than the first rotational speed, where the first threshold is greater than zero. By comparing the magnitudes of the battery heat load and the cooling capacity, it is determined that the current cooling capacity cannot meet the battery heat load demand and the cooling capacity needs to be increased. Therefore, determining to increase the rotational speed of the compressor to be greater than the first rotational speed can ensure the normal operation of the system and avoid damage to devices such as the battery due to insufficient cooling capacity.

[0066] In a possible implementation manner, when the difference between the battery heat load and the cooling capacity is less than or equal to the second threshold, it is determined that the cooling capacity provided by the compressor at this time is greater than the battery heat load demand, and the rotational speed of the compressor is adjusted to be less than the first rotational speed. By comparing the magnitudes of the battery heat load and the cooling capacity, it is determined that the cooling capacity needs to be reduced to reach an appropriate cooling capacity. Therefore, reducing the rotational speed of the compressor to be less than the first rotational speed can minimize the energy consumption of the compressor while ensuring the operation of the system.

[0067] In a possible implementation, when the difference between the battery heat load and the cooling capacity is less than the first threshold and greater than the second threshold, the cooling capacity is equivalent to the battery heat load demand, and the rotational speed of the compressor can be maintained at the current first rotational speed.

[0068] The electronic device controls the operation of the compressor according to the adjusted rotational speed of the compressor determined by the above method, so that the cooling capacity meets the battery heat load demand while minimizing power consumption as much as possible.

[0069] In a possible implementation, when the above method is applied to a server, after the server determines a first calculation model according to the battery heat load historical data and a second calculation model according to the cooling capacity historical data, the server obtains the first battery discharge voltage, the first battery discharge current, the first rotational speed, the first discharge port pressure, and the first suction port pressure sent by the vehicle. The server calculates the first battery heat load according to the first battery discharge voltage, the first battery discharge current, and the first calculation model, and calculates the first cooling capacity according to the first rotational speed, the first discharge port pressure, the first suction port pressure, and the second calculation model. The server compares the first battery heat load and the first cooling capacity, adjusts the rotational speed of the compressor, and sends the adjusted rotational speed of the compressor to the vehicle. The vehicle controls the operation of the compressor according to the obtained rotational speed of the compressor.

[0070] In summary, an air-conditioning control method provided by the present application calculates the cooling capacity by collecting the rotational speed of the compressor, the discharge port pressure of the compressor, and the suction port pressure of the compressor, compares the calculated cooling capacity with the battery heat load generated according to the battery discharge voltage and the battery discharge current, and adjusts the rotational speed of the compressor according to different magnitude relationships between the cooling capacity and the battery heat load, so as to control the vehicle-mounted air-conditioning system. Without configuring a temperature sensor, the cooling capacity can be calculated more simply according to easily collectable parameters, and the rotational speed of the compressor can be adjusted, so as to ensure that the battery temperature is within a reasonable range, reduce the power consumption of the compressor, and ensure the stable and efficient operation of the system.
