[0002] With the introduction of energy-saving and emission-reduction technologies and the increasingly stringent regulations on vehicle fuel consumption, pollutant emissions, and carbon emission control, a low-carbon development model with pure electric drive as the mainstay is gradually taking shape. With the development of electrification and intelligentization, it is not only necessary to ensure that power components maintain optimal operating temperatures, but also to demand increasingly higher energy efficiency from the entire vehicle. At the same time, people's demands for thermal comfort in vehicle heating and cooling are constantly increasing, making driving range a major pain point for new energy vehicles.

[0003] The pure electric vehicle market is developing rapidly, but the improvement in driving range is slow. The comfort of real-time temperature control in the cabin, the thermal management of the battery and electric drive assembly to ensure vehicle performance and safety, and suitable thermal management solutions to optimize driving range have become the main focus of current thermal management efforts. Especially at low temperatures, both the battery and passenger compartment need to be heated simultaneously, requiring a large amount of heat. However, current technologies suffer from energy waste, preventing effective improvements in driving range. Summary of the Invention

[0030] For a device that meets the heating conditions, the heating function of the heat storage device is activated to heat the device through the heat storage device.

[0032] If a heating request is detected in the crew compartment, a current third temperature difference is determined between the current outlet water temperature of the thermal storage tank and the current ambient temperature. If the current third temperature difference is greater than a preset third temperature difference, the crew compartment is determined to meet the heating conditions.

[0033] If a heating request from the battery is detected, a current fourth temperature difference is determined between the current outlet water temperature of the heat storage device and the current cell temperature of the battery.

[0053] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0054] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0055] Before detailing the vehicle heat control method provided in this application, the technical problem solved by this method will be explained. In the prior art, especially at low temperatures, the vehicle's battery and passenger compartment need to be heated simultaneously, resulting in a large heat demand. However, after the vehicle reaches its destination, the temperature in the passenger compartment is relatively high, generally around 24°C. After a long period of parking, the temperature gradually decreases, causing this latent heat to be wasted. Therefore, this application proposes a method to rationally utilize the vehicle's excess latent heat, thereby saving overall vehicle energy consumption and reducing energy waste. By proposing a vehicle heat control method, when the vehicle meets the heat recovery conditions, a heat storage device absorbs the heat from the heat-absorbing device that meets the heat absorption conditions, so that it can be used when heating is needed later. This solves the problem of energy waste in the prior art and effectively improves the vehicle's range.

[0056] Figure 1 is a flowchart of a vehicle heat control method provided in an embodiment of this application. This method is applicable to new energy vehicles, and is particularly suitable for recovering heat from at least one of the vehicle's passenger compartment, battery, and motor in real time during vehicle operation based on the vehicle's speed and distance to the destination. The vehicle heat control method provided in this application embodiment can be executed by a vehicle heat control device, which can be integrated into an electronic device through hardware and / or software, such as integrated into the vehicle's VCU (Vehicle Control Unit). As shown in Figure 1, the vehicle heat control method provided in this application embodiment may include the following steps:

[0057] S110. Based on the vehicle's current speed and the current distance between the vehicle and the destination, determine whether the vehicle meets the heat recovery conditions.

[0058] The current vehicle speed can be obtained through vehicle sensors, or it can be calculated based on the acceleration information and speed collected at the previous moment. The current distance can be the distance between the vehicle's current position and its destination.

[0059] In one specific implementation, before determining whether the vehicle meets the heat recovery conditions based on the vehicle's current speed and the current distance between the vehicle and the destination, the method further includes: obtaining the vehicle's current navigation information and determining the vehicle's destination based on the current navigation information; or, obtaining the vehicle's current navigation information and sending the current navigation information to the cloud so that the cloud can determine the vehicle's destination based on the vehicle's historical driving information and the current navigation information; and receiving the vehicle's destination sent by the cloud.

[0060] That is, the vehicle's destination can be obtained from the current navigation information; or, the current navigation information can be sent to the cloud, and then the cloud can determine the vehicle's destination based on the vehicle's historical driving information and the current navigation information and send it back to the vehicle. The historical driving information can include the departure point and the corresponding historical destination for each trip in the historical driving record.

[0061] For example, the cloud can first determine the origin and destination from the current navigation information, and then obtain the historical destinations corresponding to the origin from the historical driving information. The historical destination that is closest to the destination in the current navigation information is taken as the final destination. Alternatively, the final destination can be determined by combining the driving frequency of each historical destination and the distance between each historical destination and the destination in the current navigation information.

[0062] In the above implementation, when the vehicle is not connected to the cloud, the destination can be determined directly through the current navigation information. When the vehicle is connected to the cloud, the destination is determined by combining the cloud with historical driving information and current navigation information, taking into account the user's driving habits. For example, if the user's current navigation information shows the company as the destination, but the user's historical driving information shows that the historical destinations are all public parking lots near the company, then the cloud can feed back the public parking lot as the destination to the vehicle. This method can improve the accuracy of the determined destination, thereby ensuring the accuracy of determining whether the vehicle meets the heat recovery conditions.

[0063] Furthermore, after obtaining the current vehicle speed and distance, it can be determined whether the vehicle meets the conditions for heat recovery. These conditions can be used to determine if the vehicle is approaching a stop, allowing heat recovery to be activated only when the vehicle is nearing a stop, thus avoiding activation during normal driving and preventing disruption to the user's driving experience.

[0064] For example, determining whether a vehicle meets the heat recovery conditions based on its current speed and the current distance between the vehicle and its destination can be as follows: if the vehicle's current speed is less than a preset speed, and the current distance between the vehicle and its destination is less than a preset distance, then the vehicle is determined to meet the heat recovery conditions. The preset speed can be a pre-set speed threshold for when the vehicle needs to stop, such as 10 km / h; the preset distance can be a pre-set distance threshold for when the vehicle needs to stop, such as 1.5 km.

[0065] In this embodiment of the application, considering that the vehicle may not be able to recover heat through the heat storage device when the outlet water temperature of the heat storage device is high or the ambient temperature of the vehicle is low, the current ambient temperature and the current outlet water temperature of the heat storage device can also be judged. If the vehicle meets the heat recovery conditions, and the current ambient temperature is not lower than the set ambient temperature (e.g., -18°C), and the current outlet water temperature of the heat storage device does not exceed the set water temperature (e.g., 5°C), then it is further determined whether each heat absorption device meets the heat absorption conditions.

[0066] S120. If so, then based on the current temperature of at least one heat-absorbing device in the vehicle, determine whether the at least one heat-absorbing device meets the heat absorption conditions, wherein the heat-absorbing device includes the passenger compartment, battery, or motor.

[0067] Specifically, if the vehicle meets the heat recovery conditions, it can be determined whether at least one of the passenger compartment, battery, and motor meets the heat absorption conditions based on the current temperature of at least one of them.

[0068] It should be noted that the purpose of determining whether at least one of the passenger compartment, battery, and motor meets the heat absorption conditions is as follows: considering that the temperature of the passenger compartment, battery, and motor is usually high when the vehicle is about to reach its destination, the waste heat of at least one of the passenger compartment, battery, and motor can be recovered at this time to save energy.

[0069] The heat absorption condition can be used to determine whether the heat storage device can absorb heat from the heat absorption device, so as to facilitate subsequent heat recovery for the heat absorption device that can absorb heat. In the embodiments of this application, the heat absorption conditions corresponding to different heat absorption devices can be different or the same. For example, whether the heat absorption condition is met can be determined by the temperature difference between the heat storage device and the heat absorption device.

[0070] In one example, determining whether the at least one heat-absorbing device in the vehicle meets the heat absorption conditions based on the current temperature of the heat-absorbing device includes: if the heat-absorbing device includes a passenger compartment, determining a current first temperature difference between the current interior temperature of the passenger compartment and the current ambient temperature; if the current first temperature difference is greater than a preset first temperature difference, then determining that the passenger compartment meets the heat absorption conditions; if the heat-absorbing device includes a battery or a motor, determining a current second temperature difference between the current outlet temperature of the heat-absorbing device and the current outlet water temperature of the heat storage tank; if the current second temperature difference is greater than a corresponding preset second temperature difference, then determining that the heat-absorbing device meets the heat absorption conditions.

[0071] That is, if the current first temperature difference between the current interior temperature of the crew compartment and the current ambient temperature is greater than a preset first temperature difference, then the crew compartment is determined to meet the heat absorption condition. If the current second temperature difference between the current outlet temperature of the battery or motor and the current outlet water temperature of the heat storage tank is greater than the corresponding preset second temperature difference, then the battery or motor is determined to meet the heat absorption condition. The preset first temperature difference, the preset second temperature difference corresponding to the battery, and the preset second temperature difference corresponding to the motor can be the same, for example, all can be taken as 8°C.

[0072] In the above embodiments, the judgment can be made based on the ambient temperature for the passenger compartment, and based on the outlet water temperature of the heat storage device for the motor and battery. This ensures the accuracy of the judgment on whether the heat absorption device meets the heat absorption conditions, thereby avoiding the situation where the heat storage device cannot absorb heat.

[0073] S130. For a heat-absorbing device that meets the heat absorption conditions, the heat from the heat-absorbing device is absorbed by the vehicle's heat storage device, so as to determine whether to activate the heating function of the heat storage device when a heating request is detected.

[0074] Specifically, for a heat-absorbing device that meets the heat absorption conditions, heat can be recovered from it through a heat storage device. In one example, absorbing heat from the heat-absorbing device through the vehicle's heat storage device includes: if the heat-absorbing device that meets the heat absorption conditions includes a passenger compartment, controlling the vehicle's heat pump system to recover heat from the passenger compartment and storing the recovered heat in the heat storage device; if the heat-absorbing device that meets the heat absorption conditions includes a motor or battery, controlling the heat storage device to absorb heat from the heat-absorbing device.

[0075] That is, for the passenger compartment that meets the heat absorption conditions, the heat of the passenger compartment is recovered through the heat pump system and stored in the heat storage tank; for the motor or battery that meets the heat absorption conditions, the heat of the motor or battery is recovered and stored through the heat storage tank.

[0076] For example, Figure 2 is a schematic diagram of heat absorption provided in an embodiment of this application. As shown in Figure 2, since there is a certain distance between the passenger compartment and the heat storage device's installation location on the vehicle, the heat in the passenger compartment can be absorbed by the heat pump system and stored in the heat storage device. Since the battery and motor are installed adjacent to the heat storage device on the vehicle, the heat from the battery and motor does not need to be absorbed by the heat pump system and can be directly absorbed by the heat storage device. Accordingly, when the heat storage device releases heat, the heat from the heat storage device can be directly released to the battery, and the heat released by the heat storage device can be transferred to the passenger compartment through the heat pump system.

[0077] In the above embodiments, heat is recovered from the passenger compartment through a heat pump system and a heat storage device, and heat is recovered from the battery or motor through the heat storage device, ensuring the reliability of waste heat recovery from the passenger compartment, battery, and motor.

[0078] In this embodiment of the application, when the heat is absorbed by the heat storage device, the heat absorption capacity of the heat storage device can be determined in real time, so as to combine the heat absorption capacity of the heat storage device to absorb heat and realize the heat recovery by adopting the corresponding heat absorption efficiency under different conditions.

[0079] In some embodiments, absorbing heat from the heat-absorbing device through the vehicle's heat storage device includes: obtaining current heat absorption level information of the heat storage device; adjusting the valve opening of the heat storage device based on the current heat absorption level information; and absorbing heat from the heat-absorbing device through the adjusted heat storage device.

[0080] The current heat absorption level information can be used to describe the required heat absorption capacity. For example, the higher the current heat absorption level information, the stronger the required heat absorption capacity, that is, the higher the required heat absorption efficiency.

[0081] Specifically, after obtaining the current heat absorption level information, the valve opening of the heat storage device can be adjusted according to this information to adjust the heat absorption capacity of the device. This method allows for adjustment of the heat storage device's heat absorption capacity, facilitating adjustments to its heat absorption efficiency based on actual conditions. This can reduce the impact of heat absorption on the user's driving experience, or increase the heat absorption rate of the heat storage device, further preventing energy waste.

[0082] In one specific implementation, obtaining the current heat absorption level information of the thermal storage device includes at least one of the following:

[0083] Based on the current vehicle speed and current distance, the current heat absorption level information corresponding to the current vehicle speed and current distance is queried in the preset first calibration table. The preset first calibration table is used to describe the correspondence between each vehicle speed, each distance and each heat absorption level information.

[0084] The current heat absorption level of the heat storage device is determined based on the temperature difference between the current temperature of the heat absorption device and the current ambient temperature or the current outlet water temperature of the heat storage device.

[0085] Specifically, the preset first calibration table may include information on various vehicle speeds, distances, and corresponding heat absorption levels. For example, Table 1 shows a preset first calibration table, wherein, at the same vehicle speed, the heat absorption capacity described by the heat absorption level information gradually increases with increasing distance, and at the same distance, the heat absorption capacity described by the heat absorption level information gradually increases with decreasing vehicle speed.

[0086] Table 1. A Preset First Calibration Table

[0087]

[0088] For example, the vehicle speed closest to the current vehicle speed and the distance closest to the current distance can be queried in the preset first calibration table, and then the heat absorption level information corresponding to the vehicle speed and the distance in the preset first calibration table can be used as the current heat absorption level information.

[0089] This method allows for the following: when the vehicle speed is low and the distance to the destination is short, the vehicle is closer to its parking time. At this point, the heat absorption capacity of the heat storage device can be increased, thereby improving heat absorption efficiency. This allows for the recovery of all residual heat before the vehicle is turned off. Conversely, when the vehicle speed is high and the distance to the destination is long, the vehicle is less likely to be parked. In this case, the heat absorption capacity can be reduced, allowing for slower heat absorption and preventing excessive heat absorption from affecting the user's driving experience.

[0090] Specifically, for the passenger compartment, the current heat absorption level can be determined based on the temperature difference between the current temperature of the passenger compartment and the current ambient temperature. For the battery or motor, the current heat absorption level can be determined based on the temperature difference between the current temperature of the battery or motor and the current outlet water temperature of the heat storage tank. This method allows for determining the current heat absorption level based on the temperature difference, thereby increasing the heat storage tank's heat absorption capacity and efficiency when the temperature difference is large, aiming to recover all residual heat before the vehicle is turned off. Conversely, when the temperature difference is small, heat is absorbed slowly to avoid excessively rapid heat absorption that could negatively impact the user's driving experience.

[0091] Optionally, based on the temperature difference between the current temperature of the heat-absorbing device and the current ambient temperature or the current outlet water temperature of the heat storage device, the current heat absorption level information of the heat storage device is determined, including:

[0092] Based on the current temperature difference between the current temperature of the heat absorption device and the current ambient temperature or the current outlet water temperature of the heat storage device, the current heat absorption level information corresponding to the current temperature difference is queried in the preset second calibration table. The preset second calibration table is used to describe the correspondence between each temperature difference and each heat absorption level information.

[0093] Alternatively, based on the current temperature change rate of the heat-absorbing device and the current temperature difference between the current temperature of the heat-absorbing device and the current ambient temperature or the current outlet water temperature of the heat storage tank, the current heat absorption level information corresponding to the current temperature change rate and the current temperature difference can be queried in the preset third calibration table. The preset third calibration table is used to describe the correspondence between each temperature difference, each temperature difference change rate and each heat absorption level information.

[0094] That is, the current heat absorption level information can be directly queried from the preset second calibration table based on the current temperature difference between the current temperature and the current ambient temperature, or the current temperature difference between the current temperature and the current outlet water temperature.

[0095] Alternatively, the current heat absorption rating can be retrieved from a preset third calibration table based on the current temperature change rate and the current temperature difference. The current temperature change rate describes the amount of temperature change within a set interval. For example, Table 2 shows a preset third calibration table where, at the same temperature change rate, the heat absorption capacity described by the heat absorption rating gradually increases with the increase of the temperature difference; conversely, at the same temperature difference, as the temperature change rate (represented as a gradually decreasing temperature, with a negative temperature difference change rate) and an increasing rate of decrease (the absolute value of the temperature difference change rate), the heat absorption capacity described by the heat absorption rating gradually decreases.

[0096] Table 2. A Preset Third Calibration Table

[0097]

[0098] For example, a preset third calibration table can be used to find the temperature difference closest to the current temperature difference and the temperature change rate closest to the current temperature change rate. The heat absorption level information corresponding to this temperature difference and temperature change rate in the preset third calibration table can then be used as the current heat absorption level information. This method ensures that when the temperature difference is larger and the current temperature is gradually increasing at a faster rate, more heat can be absorbed, thus increasing the heat absorption capacity of the heat storage device and improving its efficiency to recover as much waste heat as possible. Conversely, when the temperature difference is smaller and the current temperature is gradually decreasing at a faster rate, less heat can be absorbed, thus reducing the heat absorption capacity of the heat storage device to avoid excessively rapid heat absorption that could negatively impact the user's driving experience.

[0099] It should be noted that, in this embodiment of the application, a current heat absorption level can be queried in a preset first calibration table based on the current vehicle speed and the current temperature, and a current heat absorption level can be queried based on the current temperature difference. Then, the minimum value among the multiple current heat absorption level information is taken as the final current heat absorption level information, so as to determine the heat absorption capacity of the heat storage device by comprehensively considering multiple factors such as vehicle speed, distance, and temperature difference, and ensure that the heat absorption efficiency of the heat storage device is more in line with actual needs.

[0100] Of course, during the heat absorption process of the heat-absorbing device that meets the heat absorption conditions, it is possible to continue to determine whether the heat-absorbing device meets the heat absorption conditions. If it does not meet the conditions, the heat absorption of the heat-absorbing device is stopped. In the embodiments of this application, after the heat storage device absorbs the heat of the heat-absorbing device that meets the heat absorption conditions, it is also possible to release heat through the heat storage device to achieve heating when the vehicle has a heating demand. For example, when a heating request is detected, it is determined whether to activate the heating function of the heat storage device. If so, heating is achieved by releasing heat through the heat storage device.

[0101] Optionally, the method provided in this application embodiment further includes: in response to detecting a heating request from at least one device to be heated, determining whether the at least one device to be heated meets the heating conditions based on the current outlet water temperature of the thermal storage tank, wherein the device to be heated includes a crew compartment or a battery; for the device to be heated that meets the heating conditions, activating the heating function of the thermal storage tank to heat the device to be heated through the thermal storage tank.

[0102] The heating request for the device to be heated can be determined based on the current temperature of the device. For example, when the vehicle is in a ready or charging state, it can be determined whether the current temperature of the device to be heated is lower than the corresponding set temperature. If so, a heating request for the device to be heated can be generated. For example, if the minimum current temperature of each cell in the battery is lower than 0°C, a heating request for the battery is generated; or, if the current temperature of the passenger compartment is lower than 8°C, a heating request for the passenger compartment is generated.

[0103] Specifically, if a heating request is received, the system determines whether the device to be heated meets the heating conditions based on the current outlet water temperature of the thermal storage tank. These heating conditions can be used to determine whether the device to be heated can be heated by the thermal storage tank.

[0104] In one example, determining whether the at least one device to be heated meets the heating conditions based on the current outlet water temperature of the heat storage device includes: when a heating request for the passenger compartment is detected, determining a current third temperature difference between the current outlet water temperature of the heat storage device and the current ambient temperature; if the current third temperature difference is greater than a preset third temperature difference, then determining that the passenger compartment meets the heating conditions; when a heating request for the battery is detected, determining a current fourth temperature difference between the current outlet water temperature of the heat storage device and the current cell temperature of the battery; if the current fourth temperature difference is greater than a preset fourth temperature difference, then determining that the battery meets the heating conditions.

[0105] That is, for the passenger compartment, the heating condition is determined to be met if the current third temperature difference between the current outlet water temperature and the current ambient temperature is greater than the preset third temperature difference; for the battery, the heating condition is determined to be met if the current fourth temperature difference between the current outlet water temperature and the current cell temperature of the battery is greater than the preset fourth temperature difference. Here, the current cell temperature can be the minimum value among the current temperatures of all cells; the preset third temperature difference can be 8℃, and the preset fourth temperature difference can be 5℃.

[0106] The above examples demonstrate that when there is a large temperature difference between the current outlet water temperature and the current ambient temperature, the heat storage device can be used to heat the passenger compartment; when there is a large temperature difference between the current outlet water temperature and the current cell temperature, the heat storage device can be used to heat the battery. This avoids situations where heating with the heat storage device would result in slow heating efficiency or failure to heat the battery when the temperature difference is small.

[0107] Specifically, if the device to be heated meets the heating conditions, it can be heated through the heat storage tank. For devices that do not meet the heating conditions, the vehicle's thermal management system can be used to heat them. In this way, the heat recovered from the heat storage tank can be used to heat the battery or passenger compartment, greatly saving energy consumption and improving the vehicle's range.

[0108] In this embodiment, in order to further save energy, considering that the vehicle's motor is usually located adjacent to the motor's installation position and that the motor temperature is high during vehicle operation, the higher-temperature motor can also be used to heat the battery to avoid consuming the heat stored in the heat storage device.

[0109] In one example, before determining whether the at least one device to be heated meets the heating conditions based on the current outlet water temperature of the heat storage device, the method further includes: if a heating request from the battery is detected, if the current temperature of the motor is lower than a preset temperature threshold, then the operation of determining whether the at least one device to be heated meets the heating conditions based on the current outlet water temperature of the heat storage device is performed; otherwise, the battery is heated by the motor.

[0110] In other words, if the battery requires heating, it can be determined whether the current temperature of the motor is below a preset temperature threshold. If so, it means the motor cannot heat the battery. In this case, it can be further determined whether the heating device meets the heating conditions, allowing heating to be performed through the heat storage device. If not, it means the motor can heat the battery, and there is no need to further determine whether the heating device meets the heating conditions; the motor can directly heat the battery. This example further utilizes the heat generated by the motor during vehicle operation, thereby further improving the vehicle's range.

[0111] In this embodiment, considering that the battery needs to reach a certain temperature quickly before it can operate when the vehicle starts, a heating priority can be set for the battery and the passenger compartment. When both the battery and the passenger compartment have heating requirements, the battery will be heated first, and the passenger compartment will be heated after the battery has been heated.

[0112] In one specific implementation, heating the device to be heated by the heat storage device includes: heating the battery by the heat storage device when it is determined that the passenger compartment meets the heating conditions and the battery meets the heating conditions; after the battery is heated, re-acquiring the current outlet water temperature of the heat storage device, determining whether the heat storage device meets the heating conditions based on the new current outlet water temperature, and if so, heating the passenger compartment by the heat storage device.

[0113] That is, if both a heating request for the passenger compartment and a heating request for the battery are detected, the battery can be heated first via the heat storage device. After the battery is heated, the current outlet water temperature of the heat storage device is re-obtained to determine whether the passenger compartment meets the heating conditions. If it does, the passenger compartment is heated again via the heat storage device. In the above embodiment, heating the battery first and then the passenger compartment via the heat storage device ensures that the battery is heated to a certain temperature first, thereby ensuring that the vehicle can start quickly.

[0114] Of course, during the heating process of a device that meets the heating conditions, it is also possible to determine in real time whether the device meets the heating cutoff condition. If so, heating of the device is stopped. Specifically, the battery can be determined to meet the heating cutoff condition when the current temperature difference between the current outlet water temperature of the heat storage tank and the current cell temperature of the battery is less than a preset fifth temperature difference, or when the current cell temperature is higher than a preset cell temperature. Similarly, the crew compartment can be determined to meet the heating cutoff condition when the current temperature difference between the current outlet water temperature of the heat storage tank and the current ambient temperature is less than a preset sixth temperature difference.

[0115] Figure 3 is a schematic diagram of a vehicle heat control process provided in an embodiment of this application. As shown in Figure 3, the vehicle's VCU can determine the vehicle's status. In the ready state, it can determine whether the distance to the destination is ≤1.5km and the vehicle speed is ≤10km / h. If not, the heat absorption function is not activated. If so, it further determines whether the ambient temperature is -18℃ ≤ and the heat storage tank outlet water temperature is ≤5℃. If not, it returns to continue determining the vehicle status. If so, the heat storage tank heat recovery function is executed when the passenger compartment temperature - ambient temperature is ≤8℃, and when the electric bridge outlet temperature - heat storage tank temperature is >8℃, or the battery outlet temperature - heat storage tank temperature is >8℃. During the execution of the heat storage tank heat recovery function, it can also continue to detect whether the electric bridge outlet temperature - heat storage tank temperature is ≤8℃, or the battery outlet temperature - heat storage tank temperature is ≤8℃. If so, heat recovery can be stopped; if not, heat recovery can continue.

[0116] Additionally, in the ready state, if the distance to the destination is ≤1.5km and the vehicle speed is ≤10km / h, it can be determined whether the battery has a heating request. If not, it can be determined whether the passenger compartment has a heating request. If the passenger compartment has a heating request, it can be determined whether the temperature difference between the heat storage tank outlet water temperature and the ambient temperature is >8℃. If it is satisfied, the heat pump recovers the energy from the heat storage tank, that is, the heat storage tank releases heat. If it is not satisfied, heating is stopped.

[0117] Referring to Figure 3, in the charging state, it can be determined whether the minimum battery cell temperature is ≤0℃. If so, it can be determined that the battery has a heating request. Then, it can be determined whether the temperature of the heat storage tank outlet water - the battery pack cell temperature is >5℃. If not, a heat pump or PCT (Positive Temperature Coefficient) device is used for heating. If so, the heat storage tank heating battery pack function is activated. During the heating process, it can continue to detect whether the temperature of the heat storage tank outlet water - the battery pack cell temperature is ≤5℃ or the minimum battery cell temperature is >5℃. If so, heating is stopped.

[0118] The vehicle heat control method provided in this application determines whether the vehicle meets the heat recovery conditions based on the vehicle's current speed and the current distance between the vehicle and its destination. If the conditions are met, the method further determines whether at least one heat-absorbing device in the vehicle meets the heat absorption conditions based on its current temperature. For heat-absorbing devices that meet the heat absorption conditions, a heat storage device absorbs the heat from the heat-absorbing device. When a heating request is detected, the method determines whether to activate the heating function of the heat storage device. This method enables heat recovery from at least one of the passenger compartment, battery, and motor that meet the heat absorption conditions. By determining whether the heat recovery conditions are met and then performing heat recovery when they are met, this method can absorb excess heat without affecting the user's riding experience or vehicle operation, so that it can be used for the next heating. This solves the problem of energy waste in the prior art and effectively improves the vehicle's driving range.

[0119] It should be noted that the method in this embodiment can be executed by a single device, such as a computer or server. The method can also be applied in a distributed scenario, where multiple devices cooperate to complete the task. In such a distributed scenario, one of these devices may execute only one or more steps of the method in this embodiment, and the multiple devices will interact with each other to complete the method described.

Furthermore, the processes depicted in the drawings do not necessarily require a specific or sequential order to achieve the desired result.
