Description

Technical Field

[0001] This application relates to the field of automation, and more specifically, to a method and apparatus for determining a target heat source, a storage medium, and an electronic device. Background Technology

[0002] Since the emergence of electric vehicles in the 1990s, their importance in the automotive market has been continuously increasing. However, the problem of reduced driving range in low temperatures remains a persistent challenge. This is due to the reduced battery discharge at low temperatures and the high energy consumption of air conditioning systems using positive temperature coefficient (PTC) thermistors. As one of the main causes of reduced driving range in low temperatures, electric vehicle air conditioning technology has been continuously developing. In 2013, Tesla's first-generation Model S used waste heat from the motor to heat the passenger compartment, marking the beginning of the waste heat utilization era for electric vehicle air conditioning technology and significantly reducing energy consumption. However, with the increase in available waste heat sources, how to accurately control and combine the waste heat from different sources to maximize passenger cabin thermal comfort has become a current challenge.

[0003] Currently, there is no effective solution to the problem of how to accurately select a heat source in existing technologies.

[0004] Therefore, it is necessary to improve the relevant technology to overcome the aforementioned defects. Summary of the Invention

[0046] The embodiments of this application will be described in detail below with reference to the accompanying drawings and examples.

[0047] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0048] The methods and embodiments provided in this application can be executed on a server device or a similar computing device. Taking running on a server device as an example, Figure 1 This is a hardware structure block diagram of a server device for a method of determining a target heat source according to an embodiment of this application. For example... Figure 1 As shown, the server device may include one or more ( Figure 1 Only one is shown in the diagram. A processor 102 (which may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.) and a memory 104 for storing data are also shown. The server device may further include a transmission device 106 for communication functions and an input / output device 108. Those skilled in the art will understand that... Figure 1 The structure shown is for illustrative purposes only and does not limit the structure of the server equipment described above. For example, the server equipment may also include components that are more... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0049] In this embodiment of the application, the computer device described above can be an on-board computer in a vehicle.

[0050] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the method for determining the target heat source in this embodiment. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, which is equivalent to implementing the above-described method. The memory 104 may include high-speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories can be connected to the computer device via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0051] The transmission device 106 of the vehicle computer typically communicates with other devices via vehicle bus systems such as CAN bus or LIN bus. These bus systems enable high-speed and reliable data transmission, and also support communication and collaboration between multiple devices.

[0052] In vehicle systems, the transmission and interaction between various devices is typically achieved through the vehicle bus system. For example, when the driver presses the brake pedal, the sensors in the braking system send signals to the vehicle controller, which then transmits instructions to the braking system via the bus system, thereby enabling the vehicle to brake.

[0053] This embodiment provides a method for determining a target heat source, which can be applied to the aforementioned computer device or vehicle-mounted computer. Figure 2 This is a flowchart of a method for determining a target heat source according to an embodiment of this application, such as... Figure 2 As shown, the process includes the following steps:

[0054] Step S202: Determine the temperature requirement value of the target object, and determine the temperature requirement of the target object based on the temperature requirement value, wherein the temperature requirement includes one of the following: cooling requirement, comfort requirement, heating requirement;

[0055] Optionally, determining the temperature requirement value of the target object includes: determining a basic temperature requirement value of the target object based on the vehicle interior temperature, the ambient temperature, and the desired temperature of the target object; determining a corrected temperature requirement value of the target object based on the amount of sunlight; and determining the temperature requirement value of the target object based on the basic temperature requirement value and the corrected temperature requirement value.

[0056] In this embodiment, the temperature requirement that meets passenger comfort is automatically calculated by comprehensively considering the in-vehicle temperature, ambient temperature, passenger's desired temperature, and sunlight intensity. Specifically:

[0057] In this embodiment of the application, the basic temperature requirement value (TaoB) is defined as the passenger's desired temperature (t). set ), vehicle interior temperature (t) r ), ambient temperature (t) am TaoB is a function of a constant (c) and has the function expression: TaoB = k set ×t set -k r ×t r -k am ×t am +c, where k set k r k am These are weighting coefficients for different ambient temperature ranges.

[0058] Among them, ambient temperature is divided into multiple segments, each corresponding to a different weighting coefficient (k value). These coefficients reflect the degree of influence of passenger set temperature, room temperature and ambient temperature on passenger comfort under different temperature conditions.

[0059] For example, firstly, the ambient temperature (referred to as ambient temperature segmentation) is divided into 7 levels, each corresponding to a temperature zone with different characteristics:

[0060] 1) External temperature segmentation 1. Extremely low temperature segmentation in northern winters: External temperature segment ≤ -13℃;

[0061] 2) External temperature segmentation 2. Low temperature segmentation in northern winters: External temperature segmentation -13℃ to -5℃;

[0062] 3) External temperature segmentation 3. Southern winter low temperature segmentation: External temperature segmentation -5℃ to 7℃;

[0063] 4) External temperature segmentation 4. Slightly cold segmentation in spring and autumn: External temperature segmentation 7℃-15℃;

[0064] 5) External temperature segmentation 5. Slightly warm segmentation in spring and autumn: External temperature segmentation 15℃-25℃;

[0065] 6) Outdoor temperature segmentation. Summer high temperature segmentation: Outdoor temperature segmentation 25℃-35℃;

[0066] 7) External temperature segmentation 7. Summer extreme high temperature segmentation: External temperature segment ≥35℃.

[0067] The values ​​of k represent the weighting percentages for different external temperature segments, and the specific values ​​are as follows:

[0068] 1) External temperature segment ≤ 4. K set =8,k r =4,k am =1.1, c=45;

[0069] 2) External temperature segment = 5. K set =8,k r =3.95, k am =1.1, c=45;

[0070] 3) External temperature segment = 6. k K set =8,k r =3.85, k am =1.1, c=45;

[0071] 4) External temperature segment = 7. K set =8,k r =3.75, k am =1.1, c=45.

[0072] The corrected temperature demand value (TaoS) is calculated by assessing the impact of solar radiation on passenger heating and cooling needs. The formula is: TaoS = K s *T s *0.86 / 60, where K s It is the solar radiation weighting coefficient, T s It is the value collected by the light sensor, i.e., the amount of sunlight.

[0073] Sunlight radiation weight K s The value of Ks depends on changes in ambient temperature. Higher ambient temperatures result in a heavier burden on light, requiring a reduction in light intensity, leading to a larger light load and a smaller Ks value. Conversely, lower ambient temperatures result in a positive benefit from light, necessitating a reduction in light intensity, and a larger Ks value. The values ​​are as follows:

[0074] For example, 1) External temperature segment ≤ 3. Ks = 0.6;

[0075] 2) External temperature segmentation = 4 / 5. Ks = 1;

[0076] 3) External temperature segment ≥ 6. Ks = 1.5.

[0077] The final temperature requirement value (TaoX) is a coupling of the basic temperature requirement value TaoB and the modified temperature requirement value TaoS. The calculation formula is: TaoX = TaoB - TaoS.

[0078] Optionally, determining the temperature requirement of the target object based on the temperature requirement value includes: determining the temperature requirement of the target object as a cooling requirement when the temperature requirement value is less than a first requirement value; determining the temperature requirement of the target object as a comfort requirement when the temperature requirement value is greater than or equal to the first requirement value and less than a second requirement value; and determining the temperature requirement of the target object as a heating requirement when the temperature requirement value is greater than or equal to the second requirement value.

[0079] When TaoX is less than the first requirement value (a), it means that the current temperature of the passenger cabin is higher than the comfort temperature set by the passenger, and the system needs to cool down the cabin temperature to meet the passenger's comfort requirements.

[0080] When TaoX is between the first demand value (a) and the second demand value (b), it is determined that the temperature in the passenger cabin is close to the passenger's set comfort temperature, or the external environment does not change much and strong cooling or heating is not required. The system will then enter the comfort adjustment mode, which may maintain the current state or make minor adjustments to cope with small temperature changes.

[0081] When TaoX is greater than or equal to the second demand value (b), it means that the temperature in the passenger cabin is lower than the comfort temperature set by the passenger, and the system needs to heat up to raise the cabin temperature and ensure passenger comfort.

[0082] The embodiments of this application can flexibly adjust these two thresholds according to actual conditions to adapt to different environmental conditions and passenger preferences. For example, as shown in Table 1, in extremely cold environments, the settings of the first demand value (a) and the second demand value (b) may be too low; in extremely hot environments, the settings of the first demand value (a) and the second demand value (b) may be too high to ensure passenger cabin comfort in low temperatures.

[0085] Step S204: If the temperature requirement is a heating requirement, determine the temperature level of the ambient temperature and determine the set of candidate heat sources based on the temperature level.

[0086] Step S206: Determine one or more target heat sources from the candidate heat source set based on the heat source temperature.

[0087] It should be noted that heat sources include motor heat sources, battery heat sources, air heat sources (obtaining heat energy from the atmosphere through an outdoor heat exchanger), and compressor short-cycle heat sources. The system needs to evaluate the temperature and energy efficiency of these heat sources to determine which heat sources can most economically meet the heating needs of the passenger cabin. If a single heat source cannot meet the demand, the combined use of heat sources will be considered. By optimizing the control strategy, the combination of heat sources with the lowest energy consumption will be found to meet the heating needs of the passenger cabin.

[0088] Through the above steps, the temperature requirement value of the target object is determined, and the temperature requirement of the target object is determined based on the temperature requirement value. The temperature requirement includes one of the following: cooling requirement, comfort requirement, or heating requirement. If the temperature requirement is heating, the ambient temperature level is determined, and a set of candidate heat sources is determined based on the temperature level. One or more target heat sources are determined from the set of candidate heat sources based on the heat source temperature. In other words, in this embodiment, by intelligently analyzing the temperature requirement of the target object and environmental conditions, the most suitable heat source can be accurately selected. This not only improves energy utilization efficiency but also allows for flexible adjustment of heat source usage strategies based on different temperature requirements and ambient temperature levels, ensuring that the temperature requirement of the target object is met and improving the user experience. Therefore, the problem of how to accurately select a heat source can be solved.

[0089] Optionally, step S204 above can be implemented in the following ways: when the temperature level is a first temperature level, the candidate heat source set is determined to be a first candidate heat source set, wherein the first candidate heat source set includes: an air heat source and a motor heat source; when the temperature level is a second temperature level, the candidate heat source set is determined to be a second candidate heat source set, wherein the second candidate heat source set includes: an air heat source, a motor heat source, a battery heat source, and a short cycle; when the temperature level is a third temperature level, the candidate heat source set is determined to be a third candidate heat source set, wherein the third candidate heat source set includes: a motor heat source, a battery heat source, and a short cycle.

[0090] This application provides a strategy for selecting a set of candidate heat sources at different temperature levels, as detailed below:

[0091] Specifically, when the temperature level is the first temperature level (e.g., external temperature segment ≥ 3), the candidate heat source set is determined to be: air heat source and motor heat source; in environments where the temperature is not very low, air heat source (i.e., absorbing heat from the external environment) and motor heat source (i.e., utilizing the heat generated by motor operation) become the preferred heat sources. Specifically, when the motor is running, the motor heat source can stably provide heat, while the air heat source depends on the temperature of the external environment.

[0092] When the temperature level is the second temperature level (e.g., ambient temperature segment = 2), the candidate heat source set is determined as follows: air heat source, motor heat source, battery heat source, and short cycle. As the ambient temperature decreases, the availability and efficiency of the battery heat source increase; therefore, at the second temperature level, the thermal management system incorporates the battery heat source as one of the alternative heat sources. Simultaneously, due to the lower temperature, short cycle supplementary heating, as a highly efficient and direct heat source, is also included in the candidate heat source set for use when passenger cabin thermal demand is high and other heat sources cannot meet it. The continued inclusion of air heat source and motor heat source as candidate heat sources indicates that, under less extreme low-temperature conditions, the combined use of multiple heat sources can more flexibly adapt to passengers' thermal comfort needs.

[0093] When the temperature level is the third temperature level (e.g., external temperature segment = 1), the candidate heat source set is determined to be: motor heat source, battery heat source, and short-cycle heat source. When the temperature drops further to the third temperature level, the heat provided by the air heat source may be very limited, or even negative, and therefore it is no longer considered a candidate heat source. Under such low-temperature conditions, the thermal management system relies primarily on the motor heat source, battery heat source, and short-cycle supplementary heating. Short-cycle supplementary heating, as a last resort, ensures that even in extremely low-temperature environments, if the heat from the motor heat source and battery heat source is insufficient to meet the heating needs of the passenger cabin, the shortfall can be compensated for by direct heating from the compressor, thus guaranteeing the temperature comfort of the passenger cabin.

[0094] Through the above strategies, the thermal management system can flexibly select and combine the most suitable heat sources under different temperature environments to achieve optimal energy efficiency and passenger comfort. Simultaneously, it eliminates reliance on high-energy-consuming PTC heaters, significantly improving the driving range of electric vehicles in low-temperature environments. This dynamic heat source selection mechanism is based on real-time monitoring of ambient temperature and precise calculation of heat source capacity.

[0095] In an exemplary embodiment, when the candidate heat source set is the first candidate heat source set, step S206 is implemented as follows: determining a first temperature difference between the motor water temperature and the ambient temperature, and determining whether the first temperature difference is greater than or equal to a first preset threshold, wherein the heat source temperature includes the motor water temperature; when the first temperature difference is greater than or equal to the first preset threshold, determining the target heat source as the motor heat source; when the first temperature difference is less than the first preset threshold, determining a second magnitude relationship between the first temperature difference and a second preset threshold; when the first temperature difference is greater than or equal to the second preset threshold, determining the target heat source as both the motor heat source and the air heat source; when the first temperature difference is less than the second preset threshold, determining the target heat source as the air heat source.

[0096] This application provides an algorithmic logic for determining one or more target heat sources to meet the thermal management requirements of the passenger cabin when a set of candidate heat sources is identified as the first candidate heat source set. Specifically:

[0097] First, calculate the difference between the motor coolant temperature and the ambient temperature, i.e., the first temperature difference. This step assesses whether the temperature of the motor heat source is high enough to be used alone, or whether it needs to be used in combination with other heat sources (such as air heat sources) to meet the heating needs of the passenger cabin.

[0098] If the first temperature difference is greater than or equal to the first preset threshold, it means that the motor water temperature has a significant thermal advantage over the air heat source. The system can directly select the motor heat source as the target heat source, meaning the system can use the motor heat source alone to meet the heating needs of the passenger cabin without needing an additional heat source. If the first temperature difference is less than the first preset threshold but greater than or equal to the second preset threshold, it indicates that the motor water temperature still has a certain thermal advantage, but it is insufficient to meet the heating needs alone. Therefore, it is decided to combine the use of the motor heat source and the air heat source to improve the overall heating efficiency and passenger cabin comfort. If the first temperature difference is less than the second preset threshold, it means that the heat provided by the motor heat source is very limited, and the system will select the air heat source as the primary heat source.

[0099] This application embodiment maximizes the use of existing heat sources under different environmental conditions, and combines multiple heat sources when necessary to provide sufficient heat while minimizing energy consumption, thereby improving the range of electric vehicles and passenger comfort in low-temperature conditions. By setting different preset thresholds, the system can intelligently select the most suitable combination of heat sources based on the difference between motor water temperature and ambient temperature, thereby optimizing the operating efficiency of the entire thermal management system.

[0100] Optionally, if the candidate heat source set is the second candidate heat source set or the third candidate heat source set, the above step S206 can also be implemented in the following way: determining the usage method of each heat source in the candidate heat source set, wherein the usage method includes one of the following: using alone, using in combination, or not using; determining one or more target heat sources in the candidate heat source set according to the usage method of each heat source in the candidate heat source set.

[0101] Standalone use: When a heat source has sufficient capacity to meet the thermal needs of the passenger cabin, that heat source will be used independently. For example, under certain conditions, if the temperature of a motor heat source or a battery heat source is high enough to meet the heating requirements, these heat sources can be activated independently.

[0102] Combined use: When a single heat source is insufficient to meet the demand, the system will consider using multiple heat sources in combination. For example, a motor heat source and a battery heat source can be used together, maximizing heating efficiency by circulating the refrigerant between different heat sources.

[0103] Not in use: If the temperature or capacity of a heat source is insufficient to meet the heating needs of the passenger cabin, the heat source will be marked as not in use.

[0104] Optionally, determining the usage mode of each heat source in the candidate heat source set includes: determining the usage mode of the battery heat source by: determining whether the battery temperature is greater than or equal to a preset minimum temperature, wherein the heat source temperature includes the battery temperature; if the battery temperature is less than the preset minimum temperature, determining that the battery heat source is not used; if the battery temperature is greater than or equal to the preset minimum temperature, determining a first low pressure corresponding to the air heat source based on the target vehicle speed and the ambient temperature, wherein the target object is associated with the target vehicle; determining a second low pressure corresponding to the motor heat source based on the motor coolant temperature, wherein the heat source temperature includes the motor coolant temperature; determining a third low pressure corresponding to the battery heat source based on the battery temperature, and determining a fourth low pressure corresponding to a short cycle; and determining the usage mode of the battery heat source based on the first low pressure, the second low pressure, the third low pressure, and the fourth low pressure.

[0105] In this embodiment, the battery temperature is first checked to see if it is greater than or equal to a preset minimum temperature. If the battery temperature is lower than the preset minimum temperature, the battery heat source is considered unusable, and the thermal management system will not use the battery's waste heat. If the battery temperature is equal to or higher than the preset minimum temperature, the usage of the battery heat source is further analyzed.

[0106] Vehicle speed and ambient temperature are important factors affecting the efficiency of air heat sources. When determining how to use an air heat source, a first low pressure needs to be obtained by consulting tables or calculations. This represents the low pressure value that the refrigerant needs to reach when utilizing the air heat source to ensure that it can effectively absorb heat from the air and convert it into heat in the passenger compartment.

[0107] The motor coolant temperature reflects the degree of waste heat generated by the motor during operation. The use of a second low-pressure source for the motor also requires determining a temperature-dependent second low-pressure source to ensure the refrigerant can effectively absorb the motor's waste heat.

[0108] The third low voltage of the battery heat source is calculated based on the battery temperature (i.e. the lowest battery temperature). This step further refines the specific application conditions of the battery heat source in the thermal management system, ensuring that the battery's waste heat can be utilized most efficiently.

[0109] As a means of heat replenishment, the corresponding fourth low pressure is another key parameter in system design. It is used to measure how the refrigerant can be directly heated by the compressor short cycle when other heat sources cannot meet the demand at extreme low temperatures.

[0110] Finally, based on the first low pressure (air source), the second low pressure (motor heat source), the third low pressure (battery heat source), and the fourth low pressure (short cycle supplemental heating), the decision-making system will select the most economical and efficient combination of heat sources to meet the heating needs of the passenger cabin.

[0111] Specifically, determining the usage mode of the battery heat source based on the first low voltage, the second low voltage, the third low voltage, and the fourth low voltage includes: determining that the battery heat source is used alone when the third low voltage is greater than or equal to the first low voltage, the third low voltage is greater than or equal to the second low voltage, and the third low voltage is greater than or equal to the fourth low voltage; and determining that the battery heat source is used in combination when the third low voltage is less than the first low voltage, the third low voltage is less than the second low voltage, and the third low voltage is greater than or equal to the fourth low voltage.

[0112] In other words, if Tgt_LP_Batt (third low pressure) > Tgt_LP_Coolant (second low pressure) & Tgt_LP_Batt > Tgt_LP_HP (first low pressure) & Tgt_LP_Batt > Tgt_CompCycle_MinLP (fourth low pressure), it means that when using a battery heat source, the pressure required for the refrigerant to absorb heat from it is higher than the pressure required to absorb heat from other heat sources. The compressor speed can be lower, and energy consumption is more economical. In this case, the battery heat source can be used independently.

[0113] If Tgt_LP_Batt>Tgt_CompCycle_MinLP, it means that using a battery heat source is only more economical than using a compressor for a shorter cycle, and can be used in conjunction with other heat sources.

[0114] Optionally, when the candidate heat source set is the second candidate heat source set, determining the usage mode of each heat source in the candidate heat source set includes: determining the usage mode of the motor heat source in the following ways: when the motor water temperature is greater than or equal to a second preset threshold and the battery heat source is not used, determining the usage mode of the motor heat source as individual use; when the motor water temperature is greater than or equal to the second preset threshold and the battery heat source is used in combination, determining the usage mode of the motor heat source as combined use; when the first temperature difference is within the range of the first threshold and the battery heat source is not used, determining the usage mode of the motor heat source as combined use, wherein the first temperature difference is the first temperature difference between the motor water temperature and the ambient temperature; when the motor water temperature is within the range of the second threshold, determining the usage mode of the motor heat source as not used.

[0115] In this embodiment of the application, the current set of candidate heat sources is determined as the second set of candidate heat sources, that is, in the current environment, multiple heat sources including motor heat sources, battery heat sources and air sources are considered.

[0116] When the motor coolant temperature is greater than or equal to the second preset threshold set by the system, and the battery heat source is set to be inactive, the motor heat source will be used independently. This indicates that under sufficiently high motor coolant temperatures, the motor heat source can independently meet the heating needs of the passenger compartment without the assistance of an additional heat source.

[0117] If the motor coolant temperature is also greater than or equal to the second preset threshold, but the battery heat source is determined to be used in combination (i.e., the battery heat source can be used simultaneously with one or more other heat sources), then the motor heat source will also operate in combination. This means that even if the motor coolant temperature is high enough, if the system determines that the combination of battery heat sources is more beneficial to energy consumption or thermal comfort, the motor heat source will also be included in this combination.

[0118] When the temperature difference between the motor coolant and the ambient temperature falls within a first threshold range set by the system, and the battery heat source is not in use, the motor heat source will be determined to be used in a combined mode. If the motor coolant temperature is within a second threshold range, the motor heat source will be determined to be not in use, and the battery heat source will be used.

[0119] In the embodiments of this application, the system utilizes the heat source not only based on the temperature of the heat source itself, but also takes into account the influence of the air heat source's capacity, so as to ensure that the coordinated work of the motor heat source and other heat sources can more effectively meet the heating needs of the passenger cabin in an environment with a small temperature difference.

[0120] Optionally, when the candidate heat source set is the second candidate heat source set, determining the usage mode of each heat source in the candidate heat source set includes: determining the usage mode of the air heat source in the following ways: when the battery heat source and the motor heat source are not used, determining the usage mode of the air heat source as individual use; when the battery heat source and / or the motor heat source are used in combination, determining the first low pressure corresponding to the air heat source and the fourth low pressure corresponding to the short cycle based on the target vehicle speed and the ambient temperature; when the first low pressure is greater than or equal to the fourth low pressure, the second temperature difference is less than the third preset threshold, and the actual air outlet temperature of the target vehicle does not meet the temperature requirement value, determining the usage mode of the air heat source as combined use, wherein the second temperature difference is the difference between the motor water temperature and the ambient temperature or the difference between the battery temperature and the ambient temperature.

[0121] When the candidate heat source set is the second candidate heat source set, how to determine the usage method of the air heat source? Specifically:

[0122] When neither the battery nor the motor heat source is in use, the air heat source will be used exclusively. This means that when the waste heat from the battery and motor is insufficient to meet the heating needs of the passenger cabin, the air heat source (such as heat from the external environment) will be used directly to heat the passenger cabin.

[0123] When battery heat sources and / or motor heat sources are selected for combined use, it is necessary to further determine whether air heat sources should also be used in combination.

[0124] This judgment is based on the target vehicle's speed, ambient temperature, and a comparison with the short-cycle heating mechanism. First, the first low pressure corresponding to the air heat source and the fourth low pressure corresponding to the short cycle are calculated. The first low pressure and the fourth low pressure are compared, and it is checked whether the second temperature difference (the difference between the motor coolant temperature and the ambient temperature or the difference between the battery temperature and the ambient temperature) is less than a third preset threshold.

[0125] If the first low pressure is greater than or equal to the fourth low pressure, and the second temperature difference is less than the third preset threshold, while the actual air outlet temperature of the target vehicle does not meet the temperature requirements set by the passengers, then the use of the air heat source is determined to be combined. This means that when the heat source capacity provided by the battery or motor is limited and cannot meet the heating requirements of the passenger compartment on its own, the air heat source will be introduced to make up for the heat source gap.

[0126] In the embodiments of this application, where possible, more economical heat sources, such as battery heat sources and motor heat sources, are preferred. However, when their capacity is insufficient to meet heating requirements, air heat sources will be considered as a supplement, especially when their low-pressure conditions are better than short-cycle supplemental heating.

[0127] Optionally, when the candidate heat source set is the second candidate heat source set, determining the usage mode of each heat source in the candidate heat source set includes: determining the usage mode of the short cycle in the following manner: when the battery heat source and / or the motor heat source and / or the air heat source are used in combination, and the actual air outlet temperature of the target vehicle does not meet the temperature requirement value, the usage mode of the short cycle is determined to be used in combination.

[0128] In this embodiment, the short cycle is activated when the battery heat source, motor heat source, and air heat source are used in combination, and the actual air outlet temperature of the target vehicle still does not meet the temperature requirements set by the passengers. The short cycle provides additional heat to the passenger compartment by directly recovering refrigerant heat from the compressor outlet, thereby replacing the PTC heater at extremely low temperatures and reducing energy consumption.

[0129] When the combined use of battery heat sources, motor heat sources, and / or air heat sources is insufficient to meet the temperature requirements of the passenger cabin, the system will activate a short loop as part of the combined use to further increase the outlet air temperature to reach the temperature requirement set by the passengers. This means that when the heating demand is very high and the conventional heat source combination is insufficient to provide enough heat, the short loop will intervene as a supplementary measure.

[0130] Optionally, when the candidate heat source set is the third candidate heat source set, determining the usage mode of each heat source in the candidate heat source set includes: determining the usage mode of the motor heat source in the following ways: when the motor water temperature is greater than or equal to a fourth preset threshold and the battery heat source is not used, determining the usage mode of the motor heat source as individual use; when the motor water temperature is greater than or equal to the fourth preset threshold and the battery heat source is used in combination, determining the usage mode of the motor heat source as combined use; when the motor water temperature is within the range of the third threshold, determining the usage mode of the motor heat source as combined use.

[0131] In this embodiment of the application, when the candidate heat source set is the third candidate heat source set, the motor water temperature (i.e. the motor coolant temperature) is greater than or equal to the fourth preset threshold (indicating that the motor has some residual heat that can be utilized), and the battery heat source is not used, the motor heat source is determined to be used alone, which means that the system will directly utilize the residual heat of the motor to meet the heating needs of the passenger cabin, avoiding unnecessary energy consumption, such as the use of PTC heaters.

[0132] When the motor coolant temperature is greater than or equal to the fourth preset threshold (the motor has available residual heat), and the battery heat source is used in combination (the battery heat source can also provide some heat, but a single heat source may not be sufficient to meet the heating demand), the motor heat source is determined to be used in combination. That is, the motor heat source will work together with the battery heat source to provide heat to the passenger compartment. This combined use method can make fuller use of the vehicle's internal residual heat resources, improve the overall energy efficiency of the thermal management system, and ensure the thermal comfort of the passenger compartment.

[0133] When the motor coolant temperature is within the third threshold range (which typically means the motor coolant temperature is too low to provide sufficient heat on its own), the motor heat source is configured for combined use, regardless of whether the battery heat source is used. This means it will work in conjunction with other heat sources to provide heat. This indicates that when the motor coolant temperature is relatively low, the system tends to combine multiple heat sources to meet the passenger cabin's heating needs, thereby improving the energy efficiency of the thermal management system and the thermal comfort of the passenger cabin.

[0134] In an exemplary embodiment, when the candidate heat source set is the third candidate heat source set, determining the usage mode of each heat source in the candidate heat source set includes: determining the usage mode of the short cycle in the following ways: when the battery heat source and the motor heat source are not used, determining the usage mode of the short cycle as: individual use; when the battery heat source and / or the motor heat source are used in combination, determining the usage mode of the short cycle as combined use.

[0135] This application provides two main usage methods for short cycles under different heat source conditions: single use and combined use.

[0136] If, under current temperature conditions, the temperature or capacity of the battery and motor heat sources is insufficient to meet the heating needs of the passenger cabin, or if they are deemed unusable for other reasons (such as the system determining that using these heat sources is uneconomical or unreasonable), then the system will activate the short cycle as a supplementary heat source, i.e., using the short cycle alone to provide additional heat. This typically occurs at extremely low temperatures when other heat sources cannot provide sufficient heat.

[0137] If at least one of the battery and motor heat sources is determined to be usable in combination with other heat sources to meet heating requirements, then the short cycle can be used in conjunction with these heat sources to form a more efficient heat replenishment mechanism. In this case, the short cycle is not merely a standalone heat source, but rather enhances the overall effectiveness of the thermal management system by working in synergy with either the battery or motor heat sources to achieve a higher energy efficiency ratio and meet more stringent passenger cabin thermal comfort requirements.

[0138] In this embodiment of the application, a flexible heat source combination strategy, especially the use of short cycles, is adopted in low-temperature environments to improve the overall heating efficiency and economy of the system, while ensuring the thermal comfort of the passenger cabin.

[0139] In an exemplary embodiment, after determining one or more target heat sources from the candidate heat source set based on the heat source temperature, the method further includes: if the target heat source includes an air heat source, controlling the release of heat through a passenger cabin heat release circuit and an air heat source circuit, wherein the passenger cabin heat release circuit includes: a compressor, a three-way valve connected in series with the compressor, and an indoor condenser connected in series with the three-way valve; the air heat source circuit includes: an outdoor heat exchanger electronic expansion valve connected in series with the indoor condenser, and an outdoor heat exchanger connected in series with the outdoor heat exchanger electronic expansion valve, the outdoor heat exchanger being connected in series with the compressor; if the target heat source includes a motor heat source, controlling the release of heat through the passenger cabin heat release circuit and the motor heat source circuit, wherein the motor heat source circuit includes: a refrigerator electronic expansion valve connected in series with the indoor condenser, a refrigerator connected in series with the refrigerator electronic expansion valve, a six-way valve connected in series with the refrigerator, a motor-driven water pump connected in series with the six-way valve, a motor connected in series with the motor-driven water pump, and a motor connected in series with the compressor. The system comprises a six-way valve connected in series with the motor, a battery-powered water pump connected in series with the six-way valve, and a refrigerator connected in series with the battery-powered water pump. The refrigerator is connected in series with the compressor. In the case where the target heat source includes a battery heat source, heat release is controlled through the passenger cabin heat release circuit and the battery heat source circuit. The battery heat source circuit includes: a refrigerator electronic expansion valve connected in series with the indoor condenser, a refrigerator connected in series with the refrigerator electronic expansion valve, a battery connected in series with the refrigerator, a six-way valve connected in series with the battery, a battery-powered water pump connected in series with the six-way valve, and a refrigerator connected in series with the battery-powered water pump. The refrigerator is connected in series with the compressor. In the case where the target heat source includes a short-cycle circuit, heat release is controlled through the passenger cabin heat release circuit and the short-cycle circuit. The short-cycle circuit includes: a refrigerator electronic expansion valve connected in series with the indoor condenser, a refrigerator connected in series with the refrigerator electronic expansion valve, a compressor electronic expansion valve connected in series with the refrigerator, and a compressor. The compressor electronic expansion valve is connected in parallel with the compressor.

[0140] To better understand the process of determining the target heat source described above, the implementation flow of the method for determining the target heat source will be further described below with reference to optional embodiments, but this is not intended to limit the technical solution of the embodiments of this application.

[0141] Based on the above algorithm, which automatically calculates the heating demand of the target object, the following thermal management system scheme is designed: Figure 3 As shown in the diagram, based on the thermal management system design, when the automatic heating and cooling demand algorithm calculates that passengers have a heating demand, a heat source selection algorithm is performed based on that demand. Specifically, in extremely low temperatures, when the compressor's short cycle is used as a supplementary heating method, the principle of prioritizing energy consumption is not considered; only whether the target heating demand of the passenger cabin can be met is taken into account.

[0142] This embodiment provides a method for determining a target heat source, which includes the following steps:

[0143] Step S1: Calculate the heat supply capacity of different heat sources. Based on the heat source temperature, calculate the pressure required for the refrigerant to absorb heat from the heat source to meet the heating needs of the passenger cabin;

[0144] 1) The correspondence between air source Tgt_LP_HP and vehicle speed and ambient temperature is shown in Table 2.

[0145] Table 2

[0146]

[0147] 2) The relationship between the motor heat source Tgt_LP_Coolant and the pump flow rate and the coolant temperature of the motor cooling circuit is shown in Table 3;

[0148] Table 3

[0149]

[0150]

[0151] 3) The relationship between battery heat source Tgt_LP_Batt and pump flow rate and minimum battery temperature is shown in Table 4;

[0152] Table 4

[0153]

[0154] 3) The correspondence between air source + water source Tgt_basicLP_mix and water temperature and ambient temperature is shown in Table 5;

[0155] Table 5

[0156]

[0157] Step S2: Identify heat sources that are potentially usable under different external temperature ranges;

[0158] Among them, external temperature segment ≥3: air source, motor heat source;

[0159] External temperature segmentation = 2: air source, motor heat source, battery heat source, short cycle;

[0160] External temperature segmentation = 1: Motor heat source, battery heat source, short cycle;

[0161] Step S3: Determine the heat source to be used;

[0162] 3.1 Determine whether a battery heat source is needed;

[0163] If the ambient temperature is low enough and the battery provides enough heat to meet the user's maximum heating needs (i.e., ambient temperature range <3, minimum battery temperature >15 degrees Celsius), then:

[0164] like

[0165] If Tgt_LP_Batt>Tgt_LP_Coolant&Tgt_LP_BatT>Tgt_LP_HP&Tgt_LP_Batt>Tgt_CompCycle_MinLP, it means that when using a battery heat source, the pressure required for the refrigerant to absorb heat from it is higher than the pressure required to absorb heat from other heat sources. The compressor speed can be lower, and the energy consumption is more economical. In this case, the battery heat source can be used alone.

[0166] If Tgt_LP_Batt>Tgt_CompCycle_MinLP, it means that using a battery heat source is only more economical than using a compressor for a shorter cycle, and can be used in conjunction with other heat sources.

[0167] 3.2 Determine whether a motor heat source is being used;

[0168] It should be noted that the motor heat source can be used under different external temperature ranges; the motor heat source should not only be considered in terms of its ability to meet the user's maximum heat demand.

[0169] 1) When the external temperature range is >= 3, and the motor water temperature - ambient temperature is > 8℃, the motor heat source is used alone; when the range is 5℃ < motor water temperature - ambient temperature > 8℃, the motor heat source is used in combination.

[0170] 2) When the external temperature segment = 2, if the motor water temperature is >5℃ and the battery heat source is not used, the motor heat source is used alone; if the motor water temperature is >5℃, the battery heat source is used and the motor heat source is used in combination; if 2℃ < motor water temperature - ambient temperature < 5℃ and the battery heat source is not used, the motor heat source is used in combination; if 2℃ < motor water temperature < 5℃, the battery heat source is used and the motor heat source is not used.

[0171] 3) When the external temperature segment = 1, if the motor water temperature is >10℃ and the battery heat source is not used, the motor heat source is used alone; if the motor water temperature is >10℃, the battery heat source is used and the motor heat source is used in combination; if -8℃ < motor water temperature <10℃, the motor heat source is used in combination.

[0172] 3.3 Determine whether the air heat source is in use;

[0173] And this is on the premise that the outdoor heat exchanger is not frozen.

[0174] 1) If the external temperature segment is ≥3, and the motor heat source is not in use, then the air source should be used.

[0175] 2) If the external temperature segment = 2, Tgt_LP_HP > Tgt_CompCycle_MinLP, meaning that the air heat source is more economical than using a short cycle, and any water-side heat source is used, and the temperature difference between the water-side heat source and the ambient temperature is within 5℃ (ensuring low-pressure balance when absorbing heat from both sides), but the actual air outlet temperature does not meet the passenger's expectations, then the air heat source is used.

[0176] 3.4 Determine whether a short loop should be used;

[0177] 1) If neither water nor air source is available. 2) If the outside temperature segment = 1, and either or both of the water-side heat source or the air-side heat source are used, then short circulation is used. 3) If the outside temperature segment = 2, and either or both of the water-side heat source or the air-side heat source are used, and the actual outlet air temperature does not meet the passenger's expectations, then short circulation is used.

[0178] Step S4: The combination of the output heat pump heat source is as follows:

[0179] 0) No demand;

[0180] 1) Separate air source;

[0181] 2) Separate electric heat source;

[0182] 3) Separate battery heat source;

[0183] 4) Electric drive heat source + battery heat source;

[0184] 5) Air source + battery heat source;

[0185] 6) Air source + electric drive heat source;

[0186] 7) Air source + electric drive heat source + battery heat source;

[0187] 8) Air source heat pump + short-circuit supplemental heating;

[0188] 9) Electric heat source + short-cycle supplemental heating;

[0189] 10) Battery heat source + short-cycle supplemental heating;

[0190] 11) Electric drive heat source + battery heat source + short cycle supplementary heating;

[0191] 12) Air source + electric heat source + short-cycle supplementary heating;

[0192] 13) Air source + battery heat source + short-cycle supplemental heating;

[0193] 14) Air source + battery heat source + electric drive heat source + short cycle supplementary heating;

[0194] 15) Pure short cycle.

[0195] The system principle of heat source combination 1 is as follows: Figure 4 As shown:

[0196] After being compressed by the compressor, the refrigerant becomes a high-temperature, high-pressure gas. It then flows entirely through a three-way valve to the indoor condenser. Because the passenger cabin temperature is lower than the refrigerant temperature in the indoor condenser, the refrigerant in the indoor condenser releases heat to the passenger cabin, undergoing a phase change. As the passenger cabin temperature rises, the refrigerant temperature in the indoor condenser drops, changing from a gas to a liquid. After being throttled and depressurized by the electronic expansion valve in the outdoor heat exchanger, the refrigerant's temperature and pressure further decrease. The refrigerant then enters the outdoor heat exchanger, absorbing heat from the warmer external environment and undergoing a phase change, returning to a low-temperature, low-pressure refrigerant before entering the compressor. During this process, the refrigerant absorbs heat from the air source, completing the heating process for the passenger cabin.

[0197] It should be noted that, Figure 4 The connection between the electronic expansion valve of the outdoor heat exchanger and the outdoor heat exchanger is represented by a solid line.

[0198] The system principle of heat source combination 2, such as Figure 5 As shown:

[0199] After being compressed by the compressor, the refrigerant becomes a high-temperature, high-pressure gas. It then flows entirely to the indoor condenser through a three-way valve. Because the passenger cabin temperature is lower than the refrigerant temperature in the indoor condenser, the refrigerant in the indoor condenser releases heat to the passenger cabin, causing a phase change. The passenger cabin temperature rises, while the refrigerant temperature in the indoor condenser drops, changing from a gas to a liquid. After being throttled and depressurized by the chiller electronic expansion valve, the refrigerant's temperature and pressure further decrease. It then absorbs heat from the water side (motor water source) through the chiller (equivalent to the refrigerator in the above embodiment) (refrigerant side). At this time, the heat from the motor heat source is pumped from port 4 of the six-way valve by the motor water pump, driven electrically to port 5 of the six-way valve, exiting from port 1 of the six-way valve, and after the battery-powered water pump increases its head, reaches the chiller (liquid side). Finally, it returns to the motor water pump through port 2 of the six-way valve, completing the heat absorption cycle from the motor water source.

[0200] It should be noted that, Figure 5 The connection between the electronic expansion valve of the outdoor heat exchanger and the outdoor heat exchanger is shown as a dashed line.

[0201] The system principle of heat source combination 3, such as Figure 6 As shown:

[0202] After being compressed by the compressor, the refrigerant becomes a high-temperature, high-pressure gas. It then flows entirely to the indoor condenser through a three-way valve. Because the passenger cabin temperature is lower than the refrigerant temperature in the indoor condenser, the refrigerant in the indoor condenser releases heat to the passenger cabin, causing a phase change. The passenger cabin temperature rises, while the refrigerant temperature in the indoor condenser drops, changing from a gas to a liquid. After being throttled and depressurized by the chiiller electronic expansion valve, the refrigerant's temperature and pressure further decrease, absorbing heat from the water side (battery water source) through the chiiller (refrigerant side). At this point, the heat from the battery heat source exits through port 3 of the six-way valve, then through port 1, and after the battery water pump increases its head, reaches the chiiller (liquid side), before returning to the battery water pump through port 3 of the six-way valve, completing the heat absorption cycle from the battery water source.

[0203] It should be noted that, Figure 6 The connection between the electronic expansion valve of the outdoor heat exchanger and the outdoor heat exchanger is shown as a dashed line.

[0204] The system principle of heat source combination 4, such as Figure 7 As shown:

[0205] After being compressed by the compressor, the refrigerant becomes a high-temperature, high-pressure gas. It then flows entirely to the indoor condenser through a three-way valve. Because the passenger cabin temperature is lower than the refrigerant temperature in the indoor condenser, the refrigerant in the indoor condenser releases heat to the passenger cabin, undergoing a phase change. The passenger cabin temperature rises, while the refrigerant temperature in the indoor condenser drops, changing from a gas to a liquid. After being throttled and depressurized by the chiiller electronic expansion valve, the refrigerant's temperature and pressure further decrease, absorbing heat from the water side (battery water source and motor heat source) through the chiiller (refrigerant side). At this point, the heat from the battery and motor heat sources exits through port 3 of the six-way valve, passes through port 1, increases the pump head, absorbs heat from the electric drive heat source, passes through port 5 of the six-way valve, reaches port 1, and then reaches the chiiller (liquid side). After passing through the battery heat source, it returns to port 4 of the six-way valve through port 3, completing the heat absorption cycle from the battery and motor water sources.

[0240] In this embodiment, the capacity of a heat source is determined by calculating the low pressure corresponding to the temperature required for the refrigerant to absorb different waste heat sources, and this is then compared with the thermal demand of the passenger cabin. If a single heat source can meet the thermal demand of the passenger cabin, a single heat source is used, and the thermal comfort of the passenger cabin is controlled by a temperature damper. If a single heat source cannot meet the thermal demand of the passenger cabin, the rationality of combining heat sources is determined by the refrigerant low pressure corresponding to the temperatures of different heat sources. If all waste heat sources cannot meet the thermal demand of the passenger cabin, a compressor short-cycle technology is used as a final heat replenishment method to replace PTC in order to meet the maximum thermal demand of the passenger cabin.
