[0022]

[0023] The embodiments of the present disclosure are described in detail below. Examples of the embodiments are shown in the accompanying drawings, and in all the accompanying drawings, the same or similar reference numerals indicate the same or similar components, or components having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to merely illustrate the present disclosure and cannot be construed as limiting the present disclosure.

[0023] In describing the present disclosure, it should be understood that directions or positional relationships indicated by terms such as "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inside," and "outside" are directions or positional relationships based on the illustrations in the drawings, are intended merely to simplify or simplify the description of the present disclosure, and do not necessarily mean or imply that the depicted devices or components are provided or constructed or operated in the specified orientation. Thus, such terms should not be understood as limiting the present disclosure.

[0024] 8 to 10, the battery heat exchange module 20 in the thermal management system according to an embodiment of the present disclosure will be first described below. The thermal management system includes a battery 300. The battery heat exchange module 20 exchanges heat with the battery 300 to cool or heat the battery 300. It should be noted that the heat exchange medium flowing in the battery heat exchange module 20 may be a fluid such as a refrigerant or water that can perform heat exchange.

[0025] As shown in FIG. 8 , a battery heat exchange module 20 according to an embodiment of the present disclosure includes a first interface 23 , a second interface 24 , a first heat exchange assembly 21 , and a second heat exchange assembly 22 .

[0026] A first end of the first heat exchange assembly 21 is connected to the first interface 23, a second end of the first heat exchange assembly 21 is connected to the second interface 24, a first end of the second heat exchange assembly 22 is connected to the first interface 23, and a second end of the second heat exchange assembly 22 is connected to the second interface 24, and the first heat exchange assembly 21 and the second heat exchange assembly 22 are configured to exchange heat with the battery. The first heat exchange assembly 21 is arranged corresponding to a first region of the battery, and the second heat exchange assembly 22 is arranged corresponding to a second region of the battery, and the first region is different from the second region.

[0027] In some embodiments of the present disclosure, the battery is divided into a first region and a second region. The division criteria for the first region and the second region may be based on the operating temperature of the region, for example, the temperature of the first region being higher than the temperature of the second region, or the temperature increase rate of the region, for example, the temperature increase rate of the first region being higher than the temperature increase rate of the second region, or the type of electrical components in the region, for example, the first region being an electrode region of the battery 300 and the second region being a non-electrode region of the battery 300. In this case, heat exchange may be performed independently on the first region and the second region by using the first heat exchange assembly 21 and the second heat exchange assembly 22 to achieve the region-divided temperature control. For example, the amount of heat exchanged by the first heat exchange assembly 21 may be greater than the amount of heat exchanged by the second heat exchange assembly 22, and during cooling, the temperature of the heat exchange medium in the first heat exchange assembly 21 may be lower than the temperature of the heat exchange medium in the second heat exchange assembly 22, or the flow rate of the heat exchange medium in the first heat exchange assembly 21 may be greater than the flow rate of the heat exchange medium in the second heat exchange assembly 22, allowing the first region to be cooled faster, thereby achieving temperature uniformity in the battery 300.

[0028] In some embodiments of the present disclosure, the temperature of the first region is different from the temperature of the second region. The different temperatures indicate that the temperature of the first region is different from the temperature of the second region when the battery is in an operating state, the operating state of the battery including charging, discharging, etc. The different temperatures may include the average temperature of the first region being different from the average temperature of the second region, the maximum temperature of the first region being different from the maximum temperature of the second region, the minimum temperature of the first region being different from the minimum temperature of the second region, or the temperature of at least a portion of the first region being different from the temperature of at least a portion of the second region at the same detection time.

[0029] Under conditions where the first region needs to dissipate heat and the second region does not, or under conditions where the first region does not need to dissipate heat and the second region needs to dissipate heat, region dissipation may be performed to reduce energy consumption. Additionally, under conditions where both the first region and the second region need to dissipate heat, it may be ensured that both the region with a relatively high heat output and the region with a relatively low heat output can dissipate heat sufficiently, thereby avoiding insufficient or excessive heat dissipation. Assuming that the operational stability and reliability of the battery heat exchange module 20 are improved, the energy consumption of the battery heat exchange module 20 can be effectively reduced.

[0030] Based on the battery heat exchange module 20 according to this embodiment of the present disclosure, the first heat exchange assembly 21 and the second heat exchange assembly 22 are arranged, and the first heat exchange assembly 21 and the second heat exchange assembly 22 may respectively cool the first area and the second area in a targeted manner. In this case, the energy consumption of the battery heat exchange module 20 can be improved, thereby improving the operation stability and reliability of the battery heat exchange module 20 and improving the temperature uniformity of the battery 300.

[0031] As shown in FIG. 8, in some embodiments, the first heat exchange assembly 21 and the second heat exchange assembly 22 are connected in parallel.

[0032] The parallel connection of the first heat exchange assembly 21 and the second heat exchange assembly 22 may be achieved by the first heat exchange assembly 21 and the second heat exchange assembly 22 sharing one first interface 23 and one second interface 24, or by the existence of multiple first interfaces 23 and multiple second interfaces 24, with the first heat exchange assembly 21 and the second heat exchange assembly 22 connected to different first interfaces 23 and different second interfaces 24, with the multiple first interfaces 23 connected to shunt pipes and the multiple second interfaces 24 connected to confluence pipes, thereby connecting the first heat exchange assembly 21 and the second heat exchange assembly 22 in parallel. The parallel-connected first heat exchange assembly 21 and the second heat exchange assembly 22 may be individually controlled by respective valves. This reduces the difficulty of control, simplifies the structure of the battery heat exchange module 20, and reduces the cost of the battery heat exchange module 20.

[0033] According to some embodiments of the present disclosure, the first heat exchange assembly 21 and the second heat exchange assembly may have different heat exchange efficiencies with the battery, such that the heat exchange efficiency of the first heat exchange assembly 21 may be higher than the heat exchange efficiency of the second heat exchange assembly 22, or the heat exchange efficiency of the first heat exchange assembly 21 may be lower than the heat exchange efficiency of the second heat exchange assembly 22.

[0034] Therefore, by using the first heat exchange assembly 21 and the second heat exchange assembly 22, heat exchange may be performed independently on the first region and the second region, thereby achieving temperature uniformity in the battery 300.

[0035] The difference in the amount of heat exchanged by the first heat exchange assembly 21 and the second heat exchange assembly 22 may be achieved by differentiating the flow rate of the cooling medium in the first heat exchange assembly 21 from the flow rate of the cooling medium in the second heat exchange assembly 22, by differentiating the heat exchange area of ​​the first heat exchange assembly 21 from the heat exchange area of ​​the second heat exchange assembly 22, and / or the like.

[0036] The heat exchange rate indicates the amount of heat dissipated into the air by the heat exchange assembly per unit time. Heat exchange efficiency = (heat exchange rate ÷ time) / (flow rate of heat exchange medium × temperature difference). The heat exchange rate ÷ time indicates the total amount of heat flowing through the heat exchange assembly from the first interface 23 to the second interface 24 within a certain time period. The flow rate indicates the flow rate of fluid on both sides of the heat exchange assembly. The temperature difference indicates the temperature difference between the fluids on both sides of the heat exchange assembly. Therefore, controlling the flow rate of the heat exchange medium, controlling the temperature difference between the heat exchange media, and differentiating the heat exchange area of ​​the first heat exchange assembly 21 from that of the second heat exchange assembly 22 can all make the heat exchange efficiency of the first heat exchange assembly 21 different from that of the second heat exchange assembly 22. The higher the heat exchange efficiency and the greater the heat exchange rate, the greater the cooling effect of the area. To achieve regional heat dissipation, the first heat exchange assembly 21 and the second heat exchange assembly 22 may be arranged corresponding to a first region and a second region, respectively, and the first region and the second region may be regions with different amounts of heat generation or different rates of temperature increase. To consider both energy consumption and temperature uniformity of the battery, the first heat exchange assembly 21 with high heat exchange efficiency is arranged in the region (first region) with a large amount of heat generation and a high rate of temperature increase, and the second heat exchange assembly 22 with low heat exchange efficiency is arranged in the region (second region) with a small amount of heat generation and a low rate of temperature increase.

[0037] As shown in FIGS. 9 and 10, according to some embodiments of the present disclosure, the first interface 23 and the second interface 24 are located on the same side of the battery heat exchange module 20.

[0038] The first heat exchange assembly 21 may be disposed corresponding to the first trunk pipe 10a, and the second heat exchange assembly 22 may be disposed corresponding to the second trunk pipe 10b, with the upstream end of the first trunk pipe 10a and the upstream end of the second trunk pipe 10b forming a first interface 23 and the downstream ends forming a second interface 24 (the upstream and downstream ends are defined based on the flow direction of the heat exchange medium). The first interface 23 and the second interface 24 are formed on the same side, allowing the battery heat exchange module 20 to communicate with a cooling loop, such as a coolant circulation system 101 or an air conditioning circulation loop 102 (as shown in FIGS. 1 and 2), in a simpler and more convenient manner. In this case, the length of the piping layout can be shortened, thereby further reducing the cost of the thermal management system 100.

[0039] As shown in FIG. 9 , some embodiments of the present disclosure include a flow path plate 25 and a covering plate 26, where a plurality of flow grooves 251 are provided on the flow path plate 25, and the covering plate 26 is disposed on the flow path plate 25 and covers the flow grooves 251 to define a first heat exchange assembly 21 and a second heat exchange assembly 22.

[0040] The covering plate 26 is divided into a first section and a second section. The plurality of flow channels 251 may be arranged in parallel and include a first portion and a second portion. The first portion corresponds to the first section of the covering plate 26 and defines the first heat exchange assembly 21. The second portion corresponds to the second section of the covering plate 26 and defines the second heat exchange assembly 22. The number, arrangement density, and through-flow area of ​​the flow channels 251 in the first portion may be greater than the number, arrangement density, and through-flow area of ​​the flow channels 251 in the second portion.

[0041] The structures of the first heat exchange assembly 21 and the second heat exchange assembly 22 according to this embodiment of the present disclosure are not limited thereto. In some other embodiments, the plurality of flow grooves 251 are divided into a first section and a second section, and the plurality of flow grooves 251 in the first section are connected in series, and the plurality of flow grooves 251 in the second section are connected in series. Alternatively, differential settings of heat exchange efficiency may be achieved by adjusting the number, arrangement density, and passing area of ​​the flow grooves 251.

[0042] As shown in FIG. 10, according to some embodiments of the present disclosure, each of the flow channels 251 includes at least one bend 252 for redirecting the fluid.

[0043] 10 shows a flow groove 251 that defines the first heat exchange assembly 21 or the second heat exchange assembly 22. The flow groove 251 may be longer and may have a larger heat exchange area and a better heat exchange effect.

[0044] It should be noted that the flow grooves 251 shown in dashed lines in Figure 10 correspond to the flow grooves 251 defining the first heat exchange assembly 21, and the flow grooves 251 shown in solid lines correspond to the flow grooves 251 defining the second heat exchange assembly 22.

[0045] 9 and 10 , in some embodiments of the present disclosure, the first interface 23 and the second interface 24 are each provided on the flow path plate 25 to communicate with the flow path groove 251, so that no piping is required between the flow path plate 25 and the first interface 23 or between the flow path plate 25 and the second interface 24. In addition, the first interface 23 and the second interface 24 may be formed as rigid interfaces, so that the stability and reliability of the connection between the first interface 23 and the external fluid loop and the connection between the second interface 24 and the external fluid loop can be improved, and the connecting piping between the first interface 23 and the flow path groove 251 and the connecting piping between the second interface 24 and the flow path groove 251 can be secured, thereby further improving the stability and safety of the battery heat exchange module 20.

[0046] The flow path plate 25 and the covering plate 26 are both integral metal components, so that the processing efficiency of the flow path plate 25 and the processing efficiency of the covering plate 26 can be improved, the processing cost can be reduced, and the sealing performance of the battery heat exchange module 20 can be guaranteed.

[0047] The first region is an electrode region, and the second region is a non-electrode region. Typically, when the battery 300 is operating, the electrodes generate a large amount of heat, causing the temperature of the electrode region to be much higher than the temperature of the non-electrode region. On one or both sides of the battery, the first heat exchange assembly 21 is correspondingly disposed in the electrode region, and the second heat exchange assembly 22 is correspondingly disposed in the non-electrode region of the battery. When the temperature of the electrode region is higher than the operating temperature of the non-electrode region, the first heat exchange assembly 21 cools the electrode region.

[0048] A thermal management system 100 according to one embodiment of the present disclosure is described below with reference to FIGS.

[0049] The thermal management system 100 according to this embodiment of the present disclosure includes a battery heat exchange module and a controller. The battery heat exchange module includes a first main pipe 10a and a second main pipe 10b. A first heat exchange assembly 21 is disposed within the first main pipe 10a, and a second heat exchange assembly 22 is disposed within the second main pipe 10b. The first heat exchange assembly 21 and the second heat exchange assembly 22 are configured to exchange heat with the battery.

[0050] The thermal management system 100 according to the present disclosure is applied to a vehicle. The vehicle may be a fuel vehicle, a gas vehicle, a new energy vehicle, or a rail vehicle. The new energy vehicle may be a battery electric vehicle, a hybrid vehicle, a long-distance electric vehicle, or the like. The battery heat exchange module in the thermal management system 100 is suitable for heat exchange with the battery of the vehicle. The battery may be used to supply power to the vehicle. For example, the battery may be used as an operating power source or a driving power source of the vehicle to replace or partially replace fuel, natural gas, or the like to provide driving power to the vehicle. Alternatively, the battery may be used to power a component of the vehicle, such as a motor, so that the battery can be used for at least one of the operating power requirements of starting, navigating, driving, or the like of the vehicle.

[0051] The first heat exchange assembly 21 and the second heat exchange assembly 22 exchange heat with the battery to adjust the temperature of the battery, so that the battery has a suitable operating temperature, thereby ensuring stable and reliable operation of the battery. For example, when the ambient temperature is relatively low in winter, the battery may be heated to increase the starting speed of the battery. As another example, when the ambient temperature is excessively high in summer or when the operating temperature of the battery is relatively high, the battery may be cooled to improve the operating safety of the battery and extend the operating life of the battery.

[0052] The thermal management system 100 according to the present disclosure further includes a controller configured to control at least one of the first trunk pipe 10a and the second trunk pipe 10b to exchange heat based on the temperature of the battery. However, the first heat exchange assembly 21 may be disposed in the first trunk pipe 10a, and the second heat exchange assembly 22 may be disposed in the second trunk pipe 10b. Thus, the controller may control one of the first heat exchange assembly 21 and the second heat exchange assembly 22 to exchange heat with the battery. The working medium circulating in the first trunk pipe 10a may be the same as or different from the working medium circulating in the second trunk pipe 10b. The working medium may be water, another liquid working medium other than water, or another medium such as carbon dioxide or a refrigerant capable of undergoing a phase change. For example, a liquid working medium circulates in the first trunk pipe 10a, and a medium capable of undergoing a phase change circulates in the second trunk pipe 10b. For example, the first trunk pipe 10a may be connected to a high-pressure cooling system or an engine cooling system, through which a coolant circulates, and the second trunk pipe 10b is connected to an air conditioning system, through which a phase-change medium circulates.

[0053] The controller may control the first heat exchange assembly 21 to exchange heat with the battery, and may also control the second heat exchange assembly 22 to exchange heat with the battery, or may control both the first heat exchange assembly 21 and the second heat exchange assembly 22 to exchange heat with the battery, which may be selected based on the actual requirements of the battery.

[0054] For example, FIG. 5 is a schematic diagram of an implementation of a battery pack according to the present disclosure. The battery pack includes a battery, a first heat exchange assembly 21, and a second heat exchange assembly 22. The battery is disposed between the first heat exchange assembly 21 and the second heat exchange assembly 22. The first heat exchange assembly 21 is disposed on one side (top) of the battery, and the second heat exchange assembly 22 is disposed on the other side (bottom) of the battery. The first heat exchange assembly is the top cover of the battery, and the second heat exchange assembly is the bottom plate of the battery. If the battery requires a very large amount of heat exchange, both the first main pipe 10a and the second main pipe 10b may be enabled for heat exchange. If the battery requires a relatively small amount of heat exchange, only one of the first main pipe 10a and the second main pipe 10b may be enabled for heat exchange. The first heat exchange assembly 21 is disposed on one side of the battery, and the second heat exchange assembly 22 is disposed on the other side of the battery. If the amount of heat generated on one side of the battery is greater than the normal operating temperature of the battery, the controller controls the heat exchange assembly corresponding to that side to cool the battery.

[0055] If the battery requires a very large amount of heat exchange, both the first main pipe 10a and the second main pipe 10b may be enabled to exchange heat. If the battery requires a relatively small amount of heat exchange, only one of the first main pipe 10a and the second main pipe 10b may be enabled to exchange heat. The first heat exchange assembly 21 is disposed on one side of the battery, and the second heat exchange assembly 22 is disposed on the other side of the battery. If the amount of heat generated on one side of the battery is greater than the normal operating temperature of the battery, the controller controls the heat exchange assembly corresponding to that side to cool the battery.

[0056] The first heat exchange assembly 21 and the second heat exchange assembly 22 are independent components and may operate independently. The first and second main pipes have different heat exchange modes. When the first and second heat exchange assemblies 21 and 22 are located in different regions of the battery, the heat exchange effects of the first and second heat exchange assemblies 21 and 22 may be reversed. For example, the first heat exchange assembly 21 heats the battery, while the second heat exchange assembly 22 cools the battery, thereby equalizing the battery temperature. The thermal management modes of the battery heat exchange module include both the first and second main pipes performing heating or cooling, and one of the first and second main pipes performing heating and the other performing cooling. Different thermal management modes are adapted based on the temperatures of different regions of the battery to equalize the battery temperature.

[0057] For example, FIG. 3 is a schematic diagram of a first implementation of a battery core according to the present disclosure, and FIG. 4 is a schematic diagram of a second implementation of a battery core according to the present disclosure. The battery includes multiple battery cores, which are arranged within the battery. Electrodes are arranged at both ends of the battery core 301. Alternatively, the electrodes may be arranged at one end of the battery core 301. When the battery core 301 is operating, the electrodes generate a large amount of heat, and the area close to the electrodes is the electrode heat-generating area, while the area far from the electrodes is the non-electrode heat-generating area. Typically, when the battery 300 is operating, the electrodes generate a large amount of heat, and the temperature of the area close to the electrodes is much higher than the temperature of the electrode area. On one or both sides of the battery, the first heat exchange assembly 21 is arranged in the electrode heat-generating temperature area 301b of the battery, and the second heat exchange assembly 22 is arranged in the non-electrode heat-generating temperature area 301a of the battery, correspondingly. When the temperature of the electrode heat generation temperature region 301b is higher than the operating temperature of the battery, the first heat exchange assembly 21 cools the electrode heat generation temperature region 301b. When the temperature of the non-electrode heat generation temperature region 301a of the battery is lower than the operating temperature of the battery, the second heat exchange assembly 22 heats the non-electrode heat generation temperature region 301a of the battery.

[0058] For example, under certain conditions, the efficiency with which the first heat exchange assembly 21 or the second heat exchange assembly 22 independently exchanges heat with the battery may be lower than the efficiency with which the first heat exchange assembly 21 and the second heat exchange assembly 22 exchange heat together. Additionally, alternatively, the first heat exchange assembly and the second heat exchange assembly may have different heat exchange efficiencies with the battery. Accordingly, the controller is configured to cause the first heat exchange assembly 21 or the second heat exchange assembly 22, or a combination of the first heat exchange assembly 21 and the second heat exchange assembly 22, to exchange heat with the battery. The battery heat exchange modules exchange heat with the battery at different efficiencies. The battery heat exchange module is caused to exchange heat with the battery at an appropriate efficiency based on the temperature of the battery. In this case, the energy consumption of the thermal management system 100 can be reduced, and the functionality of the thermal management system 100 can be improved.

[0059] According to the thermal management system 100 of this embodiment of the present disclosure, a first heat exchange assembly 21 and a second heat exchange assembly 22 are arranged, and a controller is arranged to control at least one of the first heat exchange assembly 21 and the second heat exchange assembly 22 to exchange heat with the battery. The battery heat exchange modules exchange heat with the battery at different efficiencies or in different thermal management modes. The controller controls the battery heat exchange modules to exchange heat with the battery at an appropriate efficiency or in a different thermal management mode based on the temperature of the battery. In this case, the energy consumption of the thermal management system 100 can be reduced, and the functionality of the thermal management system 100 can be improved.

[0060] In some embodiments of the present disclosure, the working medium circulates in both the first main pipe 10a and the second main pipe 10b and is suitable for exchanging heat with the battery in the first heat exchange assembly 21 and the second heat exchange assembly 22, thereby heating or cooling the battery.

[0061] In some embodiments of the present disclosure, the thermal management system 100 further includes an air conditioning circulation loop 101, the air conditioning circulation loop 101 including a heating branch, a first main pipe 10a connected in parallel to the heating branch, and a second main pipe 10b connected in parallel to the heating branch, and the controller is configured to control at least one of the heating branch, the first main pipe 10a, and the second main pipe 10b to exchange heat.

[0062] The thermal management system 100 further includes an air conditioning circulation loop 101, which is suitable for heat exchange with a passenger compartment. For example, to improve user comfort, the air conditioning circulation loop 101 may heat the passenger compartment when the ambient temperature is relatively low in winter, or may cool the passenger compartment when the ambient temperature is excessively high in summer. The working medium circulates in the air conditioning circulation loop 101, exchanges heat on the heating branch, and is suitable for heating or cooling the passenger compartment.

[0063] The heating branch of the air conditioning circulation loop 101 is configured to exchange heat with the passenger compartment to heat the passenger compartment. The heating branch is connected in parallel to both the first main pipe 10a and the second main pipe 10b. The heating branch, the first main pipe 10a, and the second main pipe 10b all operate independently of each other. The heating of the passenger compartment and the heat exchange with the battery do not compete with each other.

[0064] The controller may control the heating branches to individually exchange heat, or may control the first heat exchange assembly 21 in the first trunk pipe 10a to individually exchange heat, or may further control the second heat exchange assembly 22 in the second trunk pipe 10b to individually exchange heat. Alternatively, the controller may further control the heating branches, the first trunk pipe 10a, and the second trunk pipe 10b to perform heating in cooperation with each other. Alternatively, the controller may further control the heating branches, the first trunk pipe 10a, and the second trunk pipe 10b to exchange heat simultaneously. The controller may control the heating branches to heat the passenger compartment while controlling the battery heat exchange module to heat the battery. The controller may control the heating branches to heat the passenger compartment while controlling the battery heat exchange module to cool the battery.

[0065] In some embodiments of the present disclosure, the air conditioning circulation loop 101 includes a cooling branch, a first trunk pipe 10a is connected in parallel to the cooling branch, a second trunk pipe 10b is connected in parallel to the cooling branch, and the controller is configured to control at least one of the cooling branch, the first trunk pipe 10a, and the second trunk pipe 10b to exchange heat.

[0066] The cooling branch of the air conditioning circulation loop 101 is configured to exchange heat with the passenger compartment to cool the passenger compartment. The cooling branch is connected in parallel to both the first trunk pipe 10a and the second trunk pipe 10b. The cooling branch, the first trunk pipe 10a, and the second trunk pipe 10b all operate independently of each other. The cooling of the passenger compartment and the heat exchange with the battery do not compete with each other.

[0067] The controller may control the heating branches to exchange heat individually, or may control the first heat exchange assembly 21 in the first trunk pipe 10a to exchange heat individually, or may further control the second heat exchange assembly 22 in the second trunk pipe 10b to exchange heat individually.

The controller may control the battery heat exchange module to heat the battery while controlling the heating branches to cool the passenger compartment. The controller may further control the battery heat exchange module to cool the battery while controlling the heating branches to cool the passenger compartment.

[0068] In some embodiments of the present disclosure, the air conditioning circulation loop 101 includes a cooling branch and a heating branch. A first trunk pipe 10a is connected in parallel to the cooling branch, a second trunk pipe 10b is connected in parallel to the cooling branch, the first trunk pipe 10a is connected in parallel to the heating branch, and the second trunk pipe 10b is connected in parallel to the heating branch. The controller is configured to control at least one of the heating branch, the cooling branch, the first trunk pipe 10a, and the second trunk pipe 10b to exchange heat.

[0069] The thermal management system 100 further includes an air conditioning circulation loop 101, which is suitable for heat exchange with a passenger compartment. For example, to improve user comfort, the air conditioning circulation loop 101 may heat the passenger compartment when the ambient temperature is relatively low in winter, or may cool the passenger compartment when the ambient temperature is excessively high in summer. The air conditioning circulation loop 101 includes a cooling branch and a heating branch. The cooling branch of the air conditioning circulation loop 101 is configured to exchange heat with the passenger compartment to cool the passenger compartment. The heating branch of the air conditioning circulation loop 101 is configured to exchange heat with the passenger compartment to heat the passenger compartment. A working medium circulates through the air conditioning circulation loop 101, i.e., through the heating branch and the cooling branch, and is suitable for heating or cooling the passenger compartment.

[0070] The cooling branch is connected in parallel to both the first trunk pipe 10a and the second trunk pipe 10b. In addition, the heating branch is connected in parallel to both the first trunk pipe 10a and the second trunk pipe 10b. Therefore, the cooling branch, the heating branch, the first trunk pipe 10a, and the second trunk pipe 10b all operate independently of each other. Heat exchange with the passenger compartment and heat exchange with the battery do not compete with each other.

[0071] The controller may control the heating branches to exchange heat individually, may control the cooling branches to exchange heat individually, may control the first heat exchange assembly 21 in the first main pipe 10a to exchange heat individually, or may further control the second heat exchange assembly 22 in the second main pipe 10b to exchange heat individually.

[0072] Alternatively, the controller may further control any combination of the cooling branch, the heating branch, the first trunk pipe 10a, and the second trunk pipe 10b to exchange heat simultaneously. The controller may control the battery heat exchange module to heat the battery while controlling the cooling branch to cool the passenger compartment.

The controller may further control the battery heat exchange module to cool the battery while controlling the heating branch to heat the passenger compartment. The controller may further control the heating branch to heat the passenger compartment while controlling the cooling branch to cool the passenger compartment. The controller may further control the battery heat exchange module to exchange heat with the battery while controlling the cooling branch to cool the passenger compartment and the heating branch to heat the passenger compartment.

[0073] The cooling branch and the heating branch of the air conditioning circulation loop 101 are connected in parallel to the first main pipe 10a and the second main pipe 10b, respectively, and operate independently of each other. Control valves are arranged so that the thermal management system 100 can be controlled to achieve different functions, and different functions may be performed simultaneously. The thermal management system 100 has relatively powerful functionality, thereby improving the operating efficiency of the thermal management system 100.

[0074] In some embodiments of the present disclosure, the thermal management system 100 further includes a storage device connected between the outlet of the compressor 11 and the inlet of the compressor 11.

[0075] When the compressor 11 is operating, the working medium flows in through the intake port of the compressor 11. After being compressed by the compressor 11, the low-temperature, low-pressure gaseous working medium becomes a high-temperature, high-pressure gaseous working medium and flows out through the exhaust port of the compressor 11. After the working medium has performed heat exchange, it may return to the compressor 11 again. In this case, the circulation is completed in one cycle.

[0076] A storage device is connected between the outlet of the compressor 11 and the inlet of the compressor 11. The storage device is constructed so that the working medium can be stored and the stored working medium can be discharged. It may be understood that the state of matter of the working medium used when the working medium performs heating during heat exchange is different from the state of matter of the working medium used when the working medium performs cooling during heat exchange. For the same mass, the volume of a gaseous working medium is larger than the volume of a liquid working medium. As a result, the amount of working medium required during heating is different from the amount of working medium required during cooling. A storage device is arranged so that the working medium can be stored and the stored working medium can be discharged. The amount of working medium may be replenished or reduced based on the temperature of the battery.

[0077] A liquid working medium is easier to store. Therefore, in some embodiments of the present disclosure, the storage device may be constructed so that the working medium can be liquefied by releasing heat within the storage device, and the storage device may store the liquid working medium. The storage device may be connected between the exhaust port of the compressor 11 and the intake port of the compressor 11. The storage device may liquefy the working medium flowing out of the exhaust port of the compressor 11 and store the liquefied working medium therein.

[0078] In some embodiments of the present disclosure, the controller controls the storage device to replenish the working medium to the first trunk line 10a and / or the second trunk line 10b based on the temperature of the battery. The controller may also control the storage device to replenish the working medium to the first trunk line 10a and / or the second trunk line 10b or to deplete the working medium from the first trunk line 10a and / or the second trunk line 10b based on the temperature of the battery.

[0079] The state of matter of the working medium used when heating the battery is different from the state of matter of the working medium used when cooling the battery. Because the volume of a gaseous working medium is larger than the volume of a liquid working medium for the same mass, the amount of working medium required when heating the battery is different from the amount of working medium required when cooling the battery. When the battery heat exchange module heats the battery, the controller controls the storage device to release the stored working medium and replenish the stored working medium to the first trunk pipe 10a and / or the second trunk pipe 10b to meet the amount of working medium required when heating the battery. When the battery heat exchange module cools the battery, the storage device stores the flowing working medium and reduces the amount of working medium in the first trunk pipe 10a and / or the second trunk pipe 10b to meet the amount of working medium required when cooling the battery.

[0080] In some embodiments of the present disclosure, the storage device is configured as a liquid storage dryer configured to allow the liquid working medium to be stored and to allow the stored liquid working medium to be discharged. The liquid storage dryer may further filter moisture and impurities in the working medium to avoid damage or blockage to the working medium piping, extend the service life of the working medium piping, and facilitate the flow of the working medium.

[0081] In some embodiments of the present disclosure, the air conditioning circulation loop 101 includes a compressor 11, a first heat exchanger 12, and a second heat exchanger 13. The compressor 11 includes an intake port and an exhaust port. The exhaust port of the compressor 11, the first heat exchanger 12, the second heat exchanger 13, and the intake port of the compressor 11 are connected in sequence.

[0082] When the air conditioning circulation loop 101 is operating, the working medium flows into the intake port of the compressor 11. After being compressed by the compressor 11, the low-temperature, low-pressure gaseous working medium becomes a high-temperature, high-pressure gaseous working medium and flows out of the exhaust port of the compressor 11. A first port of the first heat exchanger 12 is connected to the exhaust port of the compressor 11, a second port of the first heat exchanger 12 is connected to the second heat exchanger 13, and the second heat exchanger 13 is connected to the intake port of the compressor 11. Therefore, after the working medium flows out of the compressor 11, it flows through the first heat exchanger 12 and then the second heat exchanger 13, performs another heat exchange, and finally returns to the compressor 11, thereby forming a working medium loop. In this case, the circulation is completed in one cycle.

[0083] The heating branch path includes a first heat exchanger 12, a first main pipe 10a is connected in parallel to the first heat exchanger 12, and a second main pipe 10b is connected in parallel to the first heat exchanger 12. The controller is configured to control the exhaust port of the compressor 11 to communicate with at least one of the first heat exchanger 12, the first main pipe 10a, and the second main pipe 10b, so as to realize heat exchange with at least one of the first heat exchanger 12, the first main pipe 10a, and the second main pipe 10b.

[0084] The heating branches are connected in parallel to the first trunk pipe 10a and the heating branches are connected in parallel to the second trunk pipe 10b. The first heat exchanger 12 on the heating branches is connected in parallel to both the first heat exchange assembly 21 in the first trunk pipe 10a and the second heat exchange assembly 22 in the second trunk pipe 10b. The first heat exchanger 12, the first heat exchange assembly 21, and the second heat exchange assembly 22 operate independently of each other.

[0085] The exhaust port of the compressor 11 is selectively connected to at least one of the heating branch, the first trunk pipe 10a, and the second trunk pipe 10b. The working medium flowing out of the exhaust port of the compressor 11 is a high-temperature, high-pressure gaseous working medium. Therefore, when the exhaust port of the compressor 11 is connected to one of the heating branch, the first trunk pipe 10a, and the second trunk pipe 10b, the heating branch, the first trunk pipe 10a, and the second trunk pipe 10b perform heating.

[0086] The controller may control the exhaust port of the compressor 11 to communicate with the heating branch to realize heat exchange by the first heat exchanger 12. The controller may further control the exhaust port of the compressor 11 to communicate with the first trunk pipe 10a to realize heat exchange by the first heat exchange assembly 21. The controller may further control the exhaust port of the compressor 11 to communicate with the second trunk pipe 10b to realize heat exchange by the second heat exchange assembly 22. The controller may further control the exhaust port of the compressor 11 to simultaneously communicate with some of the heating branch, the first trunk pipe 10a, and the second trunk pipe 10b to realize heat exchange by the first heat exchanger 12, the first heat exchange assembly 21, or the second heat exchange assembly 22. The controller may control the first heat exchanger 12 to heat the passenger compartment while controlling the battery heat exchange module to heat the battery.

[0087] In some embodiments of the present disclosure, the air conditioning circulation loop 101 includes a compressor 11, a second heat exchanger 13, and a third heat exchanger 14. The compressor 11 includes an intake port and an exhaust port. The exhaust port of the compressor 11, the second heat exchanger 13, the third heat exchanger 14, and the intake port of the compressor 11 are connected in sequence.

[0088] The cooling branch path includes a third heat exchanger 14, the first main pipe 10a is connected in parallel to the third heat exchanger 14, and the second main pipe 10b is connected in parallel to the third heat exchanger 14. The controller is configured to control the second heat exchanger 13 to communicate with at least one of the third heat exchanger 14, the first main pipe 10a, and the second main pipe 10b, to realize heat exchange with at least one of the third heat exchanger 14, the first main pipe 10a, and the second main pipe 10b.

[0089] When the air conditioning circulation loop 101 is operating, the working medium flows into the compressor 11 through its intake port. After being compressed by the compressor 11, the low-temperature, low-pressure gaseous working medium flows out of its exhaust port. The first port of the second heat exchanger 13 is connected to the exhaust port of the compressor 11, and the second port of the second heat exchanger 13 is connected to the third heat exchanger 14, which is connected to the intake port of the compressor 11. Thus, after flowing out of the compressor 11, the working medium flows through the second heat exchanger 13 and then the third heat exchanger 14. The working medium releases heat and liquefies in the second heat exchanger 13, then enters the third heat exchanger 14 after being throttled and reduced in pressure, where it absorbs heat and vaporizes, thereby performing cooling in the third heat exchanger 14. The gaseous working medium finally returns to the compressor 11, thereby forming a working medium loop. In this case, the circulation is completed in one go.

[0090] The cooling branches are connected in parallel to the first trunk pipe 10a and the cooling branches are connected in parallel to the second trunk pipe 10b. The third heat exchanger 14 on the cooling branches is connected in parallel to both the first heat exchange assembly 21 in the first trunk pipe 10a and the second heat exchange assembly 22 in the second trunk pipe 10b. The third heat exchanger 14, the first heat exchange assembly 21, and the second heat exchange assembly 22 operate independently of each other.

[0091] The controller may control the second heat exchanger 13 to communicate with the cooling branch to realize the third heat exchanger 14 performing heat exchange. The controller may further control the second heat exchanger 13 to communicate with the first main pipe 10a to realize the first heat exchange assembly 21 performing heat exchange. The controller may further control the second heat exchanger 13 to communicate with the second main pipe 10b to realize the second heat exchange assembly 22 performing heat exchange. The controller may further control the second heat exchanger 13 to simultaneously communicate with some of the cooling branch, the first main pipe 10a, and the second main pipe 10b to realize the third heat exchanger 14, the first heat exchange assembly 21, or the second heat exchange assembly 22 performing heat exchange simultaneously. The controller may control the third heat exchanger 14 to cool the passenger compartment while controlling the battery heat exchange module to cool the battery.

[0092] In some embodiments of the present disclosure, the air conditioning circulation loop 101 includes a compressor 11, a first heat exchanger 12, a second heat exchanger 13, and a third heat exchanger 14. The compressor 11 includes an intake port and an exhaust port. The exhaust port of the compressor 11, the first heat exchanger 12, the second heat exchanger 13, the third heat exchanger 14, and the intake port of the compressor 11 are connected in sequence.

[0093] When the air conditioning circulation loop 101 is operating, the working medium flows into the intake port of the compressor 11. The low-temperature, low-pressure gaseous working medium is compressed by the compressor 11 and then flows out of the exhaust port of the compressor 11 as a high-temperature, high-pressure gaseous working medium. A first port of the first heat exchanger 12 is connected to the exhaust port of the compressor 11, a second port of the first heat exchanger 12 is connected to a first port of the second heat exchanger 13, a second port of the second heat exchanger 13 is connected to a first port of the third heat exchanger 14, and a second port of the third heat exchanger 14 is connected to the intake port of the compressor 11. Therefore, after flowing out of the compressor 11, the working medium flows through the first heat exchanger 12, then the second heat exchanger 13, then the third heat exchanger 14, and finally returns to the compressor 11, thereby forming a working medium loop. In this case, the circulation is completed in one pass. The working medium exchanges heat in at least one of the first heat exchanger 12, the second heat exchanger 13, and the third heat exchanger 14. A gaseous working medium is then formed and returned to the intake of the compressor 11.

[0094] The heating branch includes a first heat exchanger 12, and the cooling branch includes a third heat exchanger 14. The first main pipe 10a is connected in parallel to the first heat exchanger 12, the second main pipe 10b is connected in parallel to the first heat exchanger 12, the first main pipe 10a is connected in parallel to the third heat exchanger 14, and the second main pipe 10b is connected in parallel to the third heat exchanger 14. The second heat exchanger 13 may be located on the heating branch. Alternatively, the second heat exchanger 13 may be located on the cooling branch. Alternatively, the second heat exchanger 13 may be used only as a pipe through which the working medium passes. The working medium neither absorbs nor releases heat in the second heat exchanger 13. This may be selected according to actual requirements.

[0095] The heating branch is connected in parallel to the first trunk pipe 10a, and the heating branch is connected in parallel to the second trunk pipe 10b. The first heat exchanger 12 on the heating branch is connected in parallel to both the first heat exchange assembly 21 in the first trunk pipe 10a and the second heat exchange assembly 22 in the second trunk pipe 10b. The first heat exchanger 12, the first heat exchange assembly 21, and the second heat exchange assembly 22 operate independently of each other. The cooling branch is connected in parallel to the first trunk pipe 10a, and the cooling branch is connected in parallel to the second trunk pipe 10b. The third heat exchanger 14 on the cooling branch is connected in parallel to both the first heat exchange assembly 21 in the first trunk pipe 10a and the second heat exchange assembly 22 in the second trunk pipe 10b. The first heat exchanger 14, the first heat exchange assembly 21, and the second heat exchange assembly 22 operate independently of each other.

[0096] The heating branch passage is connected in parallel to the first trunk pipe 10a, and the heating branch passage is connected in parallel to the second trunk pipe 10b. Therefore, the exhaust port of the compressor 11 is selectively connected to at least one of the heating branch passage, the first trunk pipe 10a, and the second trunk pipe 10b, and at least one of the heating branch passage, the first trunk pipe 10a, and the second trunk pipe 10b performs heat exchange. The working medium flowing out of the exhaust port of the compressor 11 is a high-temperature, high-pressure gas working medium. Therefore, when the exhaust port of the compressor 11 is connected to at least one of the heating branch passage, the first trunk pipe 10a, and the second trunk pipe 10b, at least one of the heating branch passage, the first trunk pipe 10a, and the second trunk pipe 10b performs heating.

[0097] The cooling branch is connected in parallel to the first trunk pipe 10a, and the cooling branch is connected in parallel to the second trunk pipe 10b, so that the intake of the compressor 11 is selectively connected to at least one of the cooling branch, the first trunk pipe 10a, and the second trunk pipe 10b. Similarly, alternatively, the second heat exchanger 13 connected to the other side of the third heat exchanger 14 is selectively connected to at least one of the cooling branch, the first trunk pipe 10a, and the second trunk pipe 10b, so that at least one of the cooling branch, the first trunk pipe 10a, and the second trunk pipe 10b performs heat exchange. At least one of the cooling branch, the first trunk pipe 10a, and the second trunk pipe 10b performs cooling.

[0098] The controller is configured to control the exhaust port of the compressor 11 to communicate with at least one of the first heat exchanger 12, the first main pipe 10a, and the second main pipe 10b, thereby realizing heat exchange between at least one of the first heat exchanger 12, the first main pipe 10a, and the second main pipe 10b.

[0099] The controller may control the exhaust port of the compressor 11 to communicate with the heating branch to realize heat exchange by the first heat exchanger 12. The controller may further control the exhaust port of the compressor 11 to communicate with the first trunk pipe 10a to realize heat exchange by the first heat exchange assembly 21. The controller may further control the exhaust port of the compressor 11 to communicate with the second trunk pipe 10b to realize heat exchange by the second heat exchange assembly 22. The controller may further control the exhaust port of the compressor 11 to simultaneously communicate with some of the heating branch, the first trunk pipe 10a, and the second trunk pipe 10b to realize heat exchange by the first heat exchanger 12, the first heat exchange assembly 21, or the second heat exchange assembly 22. The controller may control the first heat exchanger 12 to heat the passenger compartment while controlling the battery heat exchange module to heat the battery.

[0100] The controller is configured to control the realization of communication between the second heat exchanger 13 and at least one of the first main pipe 10a, the second main pipe 10b, and the third heat exchanger 14, so as to realize heat exchange between at least one of the first main pipe 10a, the second main pipe 10b, and the third heat exchanger 14.

[0101] The controller may control the second heat exchanger 13 to communicate with the cooling branch to realize the third heat exchanger 14 performing heat exchange. The controller may further control the second heat exchanger 13 to communicate with the first main pipe 10a to realize the first heat exchange assembly 21 performing heat exchange. The controller may further control the second heat exchanger 13 to communicate with the second main pipe 10b to realize the second heat exchange assembly 22 performing heat exchange. The controller may further control the second heat exchanger 13 to simultaneously communicate with some of the heating branch, the first main pipe 10a, and the second main pipe 10b to realize the third heat exchanger 14, the first heat exchange assembly 21, or the second heat exchange assembly 22 performing heat exchange simultaneously. The controller may control the third heat exchanger 14 to cool the passenger compartment while controlling the battery heat exchange module to cool the battery. The controller may control the first heat exchanger 12 to cool the passenger compartment while controlling the battery heat exchange module to heat the battery.

[0102] In some embodiments of the present disclosure, the first heat exchanger 12 is an on-board condenser 120 suitable for heating a passenger compartment. When the working medium flows through the working medium loop formed by the compressor 11 and the on-board condenser 120, the high-temperature, high-pressure gaseous working medium flowing out of the compressor 11 exhaust port exchanges heat with the on-board condenser 120. The working medium releases heat and liquefies. The working medium then undergoes throttling and pressure reduction, absorbs heat, and vaporizes, eventually becoming a low-temperature, low-pressure gaseous working medium that flows through the compressor 11 intake port. In this case, the cycle is completed in one go. The on-board condenser 120 may also function solely as a pipe, and the working medium flows through the on-board condenser 120 without heat exchange.

[0103] In some embodiments of the present disclosure, in the working medium loop formed by the compressor 11, the on-board condenser 120, and the second heat exchanger 13, the high-temperature, high-pressure gaseous working medium flowing out of the exhaust port of the compressor 11 undergoes heat exchange in the on-board condenser 120, releases heat, and is liquefied. The on-board condenser 120 is suitable for heating the passenger compartment.

[0104] The controller may control the exhaust of the compressor 11 to selectively communicate with at least one of the on-board condenser 120, the first heat exchange assembly 21, and the second heat exchange assembly 22. The controller is arranged to change the flow path of the working medium in the air conditioning circulation loop 101 so that the passenger compartment and / or the battery can be heated.

[0105] The air conditioning circulation loop 101 has a plurality of branch paths as a whole. The working medium loop formed by the compressor 11, the first heat exchanger 12, and the second heat exchanger 13 is also a part of the air conditioning circulation loop 101.

[0106] In some embodiments of the present disclosure, the second heat exchanger 13 is an off-vehicle condenser 130, and the working medium releases heat through the off-vehicle condenser 130. The off-vehicle condenser 130 may be configured to perform heating. For example, in winter, when the ambient temperature is relatively low, vehicle components need to be preheated before starting. The off-vehicle condenser 130 heats the components, and as a result, the starting speed of the vehicle can be increased. The off-vehicle condenser 130 may also function only as a pipe, and the working medium flows through the off-vehicle condenser 130 without heat exchange.

[0107] In some embodiments of the present disclosure, the third heat exchanger 14 is an evaporator 140, which is suitable for cooling the passenger compartment.

[0108] When the working medium flows through the working medium loop formed by the compressor 11 and the evaporator 140, the high-temperature, high-pressure gaseous working medium flowing out of the compressor 11 exhaust port first exchanges heat within the piping. The working medium releases heat and liquefies. The working medium then undergoes throttling and pressure reduction, enters the evaporator 140, where it absorbs heat and vaporizes, cooling the evaporator 140. Finally, it becomes a low-temperature, low-pressure gaseous working medium, which flows into the compressor 11 through the intake port. In this case, the circulation is completed in one cycle.

[0109] In some embodiments of the present disclosure, in the working medium loop formed by the compressor 11, the second heat exchanger 13, and the evaporator 140, the high-temperature, high-pressure gaseous working medium flowing out of the compressor 11 exhaust port exchanges heat in the second heat exchanger 13. The working medium releases heat and liquefies. The working medium then undergoes throttling and pressure reduction, enters the evaporator 140, absorbs heat, and vaporizes in the evaporator 140 suitable for cooling the passenger compartment, and finally becomes a low-temperature, low-pressure gaseous working medium that flows into the compressor 11 intake port. In this case, the circulation is completed in one cycle.

[0110] The controller may control the second heat exchanger 13 to selectively communicate with at least one of the evaporator 140, the first heat exchange assembly 21, and the second heat exchange assembly 22. The controller is arranged to change the flow path of the working medium in the air conditioning circulation loop 101 so that the passenger compartment and / or the battery can be cooled.

[0111] In some embodiments of the present disclosure, in the working medium loop formed by the compressor 11, the on-board condenser 120, the off-vehicle condenser 130, and the evaporator 140, the high-temperature, high-pressure gaseous working medium flowing out of the exhaust port of the compressor 11 exchanges heat in the on-board condenser 120. The working medium releases heat and liquefies. The on-board condenser 120 is suitable for heating the passenger compartment. The on-board condenser 120 may also function only as a flow path, and the working medium flows through the on-board condenser 120 without heat exchange. The working medium may then continue to flow to the off-vehicle condenser 130, where it exchanges heat again and releases heat. The working medium may also simply pass through the off-vehicle condenser 130 without heat exchange there. The working medium that has released heat and become liquid undergoes throttling and pressure reduction, enters the evaporator 140, absorbs heat and vaporizes in the evaporator 140 suitable for cooling the passenger compartment, and finally becomes a low-temperature, low-pressure gaseous working medium that flows into the intake port of the compressor 11. In this case, the circulation is completed in one cycle.

[0112] The controller may control the exhaust port of the compressor 11 to selectively communicate with at least one of the on-board condenser 120, the first heat exchange assembly 21, and the second heat exchange assembly 22, and may further control the second heat exchanger 13 to selectively communicate with at least one of the evaporator 140, the first heat exchange assembly 21, and the second heat exchange assembly 22. The controller is configured to change the flow path of the working medium in the air conditioning circulation loop 101 to enable the thermal management system 100 to operate under different conditions. The thermal management system 100 according to the present disclosure has powerful functionality.

[0113] When the controller controls the compressor 11 so that the exhaust port is connected to the on-board condenser 120, controls the off-board condenser 130 so that the exhaust port is connected to the evaporator 140, and controls the compressor 11 so that the exhaust port is not connected to the first trunk pipe 10a or the second trunk pipe 10b, the working medium does not exchange heat through the on-board condenser 120, but releases heat through the off-board condenser 130 and absorbs heat through the evaporator 140. The thermal management system 100 may realize a condition in which the passenger compartment is cooled separately.

[0114] When the controller controls the compressor 11 so that the exhaust port is connected to the on-board condenser 120, controls the off-board condenser 130 so that the exhaust port is connected to the first trunk pipe 10a and the second trunk pipe 10b, controls the compressor 11 so that the exhaust port is not connected to the first trunk pipe 10a or the second trunk pipe 10b, and the off-board condenser 130 is not connected to the evaporator 140, the working medium does not exchange heat through the on-board condenser 120, releases heat through the off-board condenser 130, and absorbs heat through the first heat exchange assembly 21 and / or the second heat exchange assembly 22. The thermal management system 100 may realize a condition in which the battery is cooled.

[0115] When the controller controls the compressor 11 so that the exhaust port is connected to the on-board condenser 120, the off-board condenser 130 so that the first trunk pipe 10a and the second trunk pipe 10b are connected, and the off-board condenser 130 is connected to the evaporator 140, and the controller controls the compressor 11 so that the exhaust port is not connected to the first trunk pipe 10a or the second trunk pipe 10b, the working medium does not exchange heat through the on-board condenser 120, but releases heat through the off-board condenser 130, absorbs heat through the first heat exchange assembly 21 and / or the second heat exchange assembly 22, and absorbs heat through the evaporator 140. The thermal management system 100 may realize a condition in which both the battery and the passenger compartment are cooled.

[0116] When the controller controls the exhaust port of the compressor 11 to communicate with the on-board condenser 120 and controls the exhaust port of the compressor 11 not to communicate with the first trunk pipe 10a or the second trunk pipe 10b, the working medium releases heat through the on-board condenser 120. The thermal management system 100 may realize a condition in which the passenger compartment is heated.

[0117] When the controller controls the compressor 11 so that the exhaust port is in communication with the first trunk pipe 10a and the second trunk pipe 10b, and controls the compressor 11 so that the exhaust port is not in communication with the on-board condenser 120, the working medium releases heat through the first heat exchange assembly 21 and / or the second heat exchange assembly 22. The thermal management system 100 may realize a condition in which the battery is heated.

[0118] When the controller controls the exhaust port of the compressor 11 to communicate with the on-board condenser 120 and the exhaust port of the compressor 11 to communicate with the first trunk pipe 10a and the second trunk pipe 10b, the working medium releases heat through the on-board condenser 120 and the first heat exchange assembly 21 and / or the second heat exchange assembly 22. The thermal management system 100 may realize a condition in which both the passenger compartment and the battery are heated.

[0119] In some embodiments of the present disclosure, the thermal management system 100 includes a first exhaust passage 10c. The battery heat exchange module is connected to the air intake through the first exhaust passage 10c. The working medium flowing through the battery heat exchange module may return to the air intake through the first exhaust passage 10c. For example, when cooling the battery, the working medium flows out of the exhaust port, releases heat through the off-vehicle condenser 130, absorbs heat in the battery heat exchange module, and then returns to the air intake through the first exhaust passage 10c.

[0120] The thermal management system 100 further includes a second exhaust passage 10d connected to the exhaust port, and the second exhaust passage 10d is connected to the first exhaust passage 10c. Therefore, the battery heat exchange module is also connected to the exhaust port via the second exhaust passage 10d, and the working medium may flow through the second exhaust passage 10d to the battery heat exchange module. For example, when heating the battery, the working medium flows out of the exhaust port, through the second exhaust passage to the battery heat exchange module, and releases heat in the battery heat exchange module.

[0121] The thermal management system 100 further includes a third exhaust passage 10e that allows the exhaust port to communicate with the on-board condenser 120. The working medium may flow through the third exhaust passage 10e to the off-vehicle condenser 130 and release heat in the on-board condenser 120.

[0122] In some embodiments of the present disclosure, the controller includes a plurality of control valves that are operated to communicate with the exhaust outlet along with at least one of the on-board condenser 120 and the battery heat exchange module to direct the working medium in the exhaust outlet to the on-board condenser 120 or the battery heat exchange module. The control valves are arranged such that the direction of the working medium can be controlled to control the operation of the thermal management system 100.

[0123] In some embodiments of the present disclosure, the control valve group includes a first on-off valve 51, a second on-off valve 52, and a third on-off valve 53. The first on-off valve 51 is connected in series to the second exhaust passage 10d. The third on-off valve 53 is connected between the off-vehicle condenser 130 and the exhaust port, i.e., the third on-off valve 53 is connected in series to the third exhaust passage 10e. The second on-off valve 52 is connected in series to the first exhaust passage 10c, and when the second on-off valve 52 is closed, the working medium in the second exhaust passage 10d is prevented from flowing to the return air port.

[0124] The first on-off valve 51 may control the opening and closing of the second exhaust passage 10d to control whether the working medium flows from the exhaust port to the battery heat exchange module. When the first on-off valve 51 is closed, the working medium is prevented from flowing to the battery heat exchange module. The third on-off valve 53 may control the opening and closing of the third exhaust passage to control whether the working medium flows from the exhaust port to the off-vehicle condenser 130. When the third on-off valve 53 is closed, the working medium is prevented from flowing to the off-vehicle condenser 130.

[0125] The first exhaust passage 10c is connected to the return air port, the second exhaust passage 10d is connected to the exhaust port, and the second exhaust passage 10d is connected to the first exhaust passage 10c. When the first on-off valve 51 controls circulation through the second exhaust passage 10d, the working medium flowing out of the exhaust port flows from the second exhaust passage 10d to the first exhaust passage 10c and then directly returns to the return air port. Therefore, the second on-off valve 52 is disposed on the first exhaust passage 10c, so that the second on-off valve 52 can control the opening and closing of the first exhaust passage 10c. When the second on-off valve 52 is closed, the working medium in the second exhaust passage 10d is prevented from flowing to the intake port.

[0126] In some embodiments of the present disclosure, a fourth electronic expansion valve 64 is further included, and the fourth electronic expansion valve 64 is connected in parallel to the third on-off valve 53 .

The first switching valve 41 may control opening and closing between the battery heat exchange module and the third heat exchanger 14, and the second switching valve 42 may control opening and closing between the battery heat exchange module and the second heat exchanger 13. When one of the first switching valve 41 and the second switching valve 42 is turned on, the first main pipe 10a is connected in parallel to the first heat exchanger 12, the second main pipe 10b is connected in parallel to the first heat exchanger 12, the first main pipe 10a is connected in parallel to the third heat exchanger 14, and the second main pipe 10b is connected in parallel to the third heat exchanger 14.

In addition, the second one-way valve 42 may operate stably and continuously, thereby reducing active control and facilitating control.

[0130] According to some embodiments of the present disclosure, the first sensor 31 and the second sensor 32 are disposed in the first main pipe 10a, with the first sensor 31 located at a first end of the first heat exchange assembly 21 and the second sensor 32 located at a second end of the first heat exchange assembly 21. The third sensor 33 and the fourth sensor 34 are disposed in the second main pipe 10b, with the third sensor 33 located at a first end of the second heat exchange assembly 22 and the fourth sensor 34 located at a second end of the second heat exchange assembly 22.

[0131] Sensors are arranged so that various values ​​of the working medium in the first trunk pipe 10a and various values ​​of the working medium in the second trunk pipe 10b can be obtained intuitively and accurately. The controller may control the flow conditions of the working medium in the first trunk pipe 10a and the second trunk pipe 10b based on the battery temperature. This is not only convenient for operation, but also allows the battery to quickly reach a suitable operating temperature, thereby improving the operating stability of the battery.

[0132] In some embodiments of the present disclosure, the first sensor 31 may be constructed as a pressure sensor and may acquire the pressure of the working medium in the first main pipe 10a. The second sensor 32 may be constructed as a temperature sensor and may acquire the temperature of the working medium in the first main pipe 10a. The third sensor 33 may be constructed as a pressure sensor and may acquire the pressure of the working medium in the second main pipe 10b. The fourth sensor 34 may be constructed as a temperature sensor and may acquire the temperature of the working medium in the second main pipe 10b.

[0133] In some embodiments of the present disclosure, a first sensor 31, a second sensor 32, and a first flow rate regulating element are disposed in the first trunk pipe 10a. The first sensor 31 is located at a first end of the first heat exchange assembly 21. The first flow rate regulating element is located at a second end of the first heat exchange assembly 21. The second sensor 32 is disposed between the second end of the first heat exchange assembly 21 and the first flow rate regulating element.

The fourth sensor 34 may be constructed as a temperature sensor and may acquire the temperature of the working medium in the second main pipe 10b.

[0135] The first flow regulating element may adjust the flow rate of the working medium in the first trunk pipe 10a, thereby adjusting the pressure in the first trunk pipe 10a and fulfilling the roles of throttling and decompression. The second flow regulating element may adjust the flow rate of the working medium in the second trunk pipe 10b, thereby adjusting the pressure in the second trunk pipe 10b and fulfilling the roles of throttling and decompression. The pressures of the working medium in the first trunk pipe 10a and the second trunk pipe 10b are kept within a safe range to prevent excessive pressure of the working medium in the first trunk pipe 10a and the second trunk pipe 10b from breaking through the piping and damaging the battery, thereby improving the operational stability of the battery.

[0136] When the working medium flows through the working medium loop formed by the compressor 11, the on-board condenser 120, the off-board condenser 130, and the battery heat exchange module, the working medium releases heat in the on-board condenser 120 or the off-board condenser 130, and then becomes a low-temperature, low-pressure liquid working medium after being throttled and reduced in pressure by the first flow rate adjusting element and / or the second flow rate adjusting element. The working medium absorbs heat and vaporizes in the battery heat exchange module, and then becomes a low-temperature, low-pressure gaseous working medium. The low-temperature, low-pressure gaseous working medium flows into the compressor 11 through the intake port. In this case, the circulation is completed in one cycle.

[0137] In some embodiments of the present disclosure, the heat exchange element further includes a third switching valve and a fourth switching valve, the third switching valve being disposed in the first trunk pipe 10a and the fourth switching valve being disposed in the second trunk pipe 10b.

[0138] To control the flow or stagnation of the working medium in the first trunk pipe 10a or the second trunk pipe 10b, the third selector valve may control the opening and closing of the first trunk pipe 10a, and the fourth selector valve may control the opening and closing of the second trunk pipe 10b. The third selector valve and the fourth selector valve operate independently of each other.

[0139] When the third switching valve is turned on, the first main pipe 10a is connected in parallel to the third heat exchanger 14, and the first main pipe 10a is selectively connected in parallel to the first heat exchanger 12. When the fourth switching valve is turned on, the second main pipe 10b is connected in parallel to the third heat exchanger 14, and the second main pipe 10b is selectively connected in parallel to the first heat exchanger 12.

[0140] In some embodiments of the present disclosure, a first electronic expansion valve 61 is disposed in the first main pipe 10a, and a second electronic expansion valve 62 is disposed in the second main pipe 10b. A first sensor 31 is located at a first end of the first heat exchange assembly 21, the first electronic expansion valve 61 is located at a second end of the first heat exchange assembly 21, and the second sensor 32 is disposed between the second end of the first heat exchange assembly 21 and the first electronic expansion valve 61.

[0141] The electronic expansion valve may have a flow control function and reduce the pressure of the working medium flowing through it. The electronic expansion valve may also have an opening / closing function and selectively close the piping in which the electronic expansion valve is located to control the flow or stagnation of the working medium in the piping. Therefore, the first electronic expansion valve 61 may be disposed in the first main pipe 10a, and the first flow control element and the third selector valve may be omitted. Similarly, the second electronic expansion valve 62 may be disposed in the second main pipe 10b, and the second flow control element and the fourth selector valve may be omitted, thereby reducing the number of components and easing the difficulty of layout.

[0142] In some embodiments of the present disclosure, a fifth switching valve is disposed at a first end of the evaporator 140, and the fifth switching valve is connected in series between the evaporator 140 and the intake port of the compressor 11. The fifth switching valve may control the opening and closing of a pipe in which the evaporator 140 is located. When the fifth switching valve is open, the working medium may flow through the evaporator 140 to the compressor 11.

[0143] In some embodiments of the present disclosure, the fifth switching valve is configured as a third one-way valve 43, and the third one-way valve 43 is configured to allow the working medium to flow from the evaporator 140 to the compressor 11. The third one-way valve 43 may control the working medium to flow steadily from the evaporator 140 to the compressor 11, thereby improving the fluidity of the working medium, preventing backflow of the working medium, and improving the operational stability of the thermal management system 100. In addition, the third one-way valve 43 may operate stably and continuously, thereby reducing active control and facilitating control.

[0144] In some embodiments of the present disclosure, a third electronic expansion valve 63 is disposed at the second end of the evaporator 140, and the third electronic expansion valve 63 is connected in series between the off-vehicle condenser 130 and the evaporator 140. The electronic expansion valve has a flow rate regulation function, and the third electronic expansion valve 63 may reduce the pressure of the working medium flowing through the third electronic expansion valve 63. The electronic expansion valve may further have an opening / closing function, and may selectively close a pipe to control whether the working medium flows to the evaporator 140.

[0145] When the working medium flows through the working medium loop formed by the compressor 11, the on-board condenser 120, the off-board condenser 130, and the evaporator 140, the working medium releases heat in the on-board condenser 120 or the off-board condenser 130, and then becomes a low-temperature, low-pressure liquid working medium after being throttled and reduced in pressure by the third electronic expansion valve 63. The working medium absorbs heat and vaporizes in the evaporator 140, becoming a low-temperature, low-pressure gaseous working medium. The low-temperature, low-pressure gaseous working medium flows into the compressor 11 through the intake port. In this case, the circulation is completed in one cycle.

[0146] In some embodiments of the present disclosure, the thermal management system 100 further includes a bypass flow path 10f, which is connected in series to the fourth on-off valve 54 and in parallel to the fifth switching valve, the evaporator 140, and the third electronic expansion valve 63, which are connected in parallel. The fourth on-off valve 54 may control the flow and isolation of the bypass flow path 10f. When the fourth on-off valve 54 opens the bypass flow path 10f, the working medium returns to the intake port through the bypass flow path 10f. When the fourth on-off valve 54 closes the bypass flow path 10f, the working medium returns to the intake port through the flow path in which the evaporator 140 is located.

[0147] In the embodiment of the present disclosure, the fifth on-off valve 55 is disposed at a first end of the off-vehicle condenser 130, and the fifth on-off valve 55 is connected in series between the off-vehicle condenser 130 and the exhaust port of the compressor 11. When the fifth on-off valve 55 is turned on, the working medium may flow to the off-vehicle condenser 130.

[0148] In some embodiments of the present disclosure, the fourth one-way valve 44 is disposed at the second end of the off-vehicle condenser 130, and the fourth one-way valve 44 is constructed to allow the working medium to flow out of the off-vehicle condenser 130, thereby improving the fluidity of the working medium and preventing the working medium from flowing back.

[0149] In some embodiments of the present disclosure, the thermal management system 100 further includes a sixth on-off valve 56. The sixth on-off valve 56 is disposed on a side of the first switching valve 41 away from the battery heat exchange module. When the sixth on-off valve 56 is turned on, the working medium may flow from the battery heat exchange module to the evaporator 140.

[0150] In some embodiments of the present disclosure, the thermal management system 100 further includes a fifth one-way valve 45. The fifth one-way valve 45 is disposed between the battery heat exchange module and the intake port of the compressor 11. The fifth one-way valve 45 is constructed to allow the working medium to flow from the battery heat exchange module to the intake port of the compressor 11, thereby preventing the working medium flowing into the intake port from flowing into the heat exchange component and improving the safety of use of the heat exchange component.

[0151] In some embodiments of the present disclosure, the thermal management system 100 further includes a gas-liquid separator 15. The gas-liquid separator 15 is connected to the intake of the compressor 11. After the working medium is throttled and vaporized, it becomes a low-temperature, low-pressure gaseous working medium. Because it cannot be completely guaranteed that all of the working medium is converted into a gaseous working medium through heat absorption and vaporization, the working medium must first flow into the gas-liquid separator 15 before flowing back into the compressor 11. The gas-liquid separator 15 separates the gaseous working medium from the liquid working medium and drives only the low-temperature, low-pressure gaseous working medium to flow into the compressor 11, thereby avoiding liquid collisions of liquid droplets on functional components in the compressor 11 and ensuring the safe and normal operation of the compressor 11.

[0152] In some embodiments of the present disclosure, the thermal management system 100 further includes a series branch 10g, one end of which is connected to the first trunk pipe 10a and the other end of which is connected to the second trunk pipe 10b. The controller is further configured to control, based on the temperature of the battery, the series branch 10g to realize a series connection between the first trunk pipe 10a and the second trunk pipe 10b, so that both the first trunk pipe 10a and the second trunk pipe 10b exchange heat.

[0153] In some embodiments of the present disclosure, the first interface of the first heat exchange assembly 21 is connected via a series branch 10g to the second interface of the second heat exchange assembly 22. The working medium enters the second interface of the first heat exchange assembly 21, then flows through the first heat exchange assembly 21, then flows through the series branch 10g to the second heat exchange assembly 22, and finally exits the first interface of the second heat exchange assembly 22.

[0154] In some embodiments of the present disclosure, the series branch 10g includes a series selector valve 57, and the first interface of the first heat exchange assembly 21 is connected to the second interface of the second heat exchange assembly 22 via the series selector valve 57. The series selector valve 57 may control the opening and closing of the series branch 10g. When the series selector valve 57 disconnects the series branch 10g, the first trunk 10a and the second trunk 10b may be connected in parallel. When the series selector valve 57 connects the series branch 10g, the first trunk 10a and the second trunk 10b may be connected in series.

[0155] In some embodiments of the present disclosure, the first sensor 31 is disposed between one end of the series branch 10g and the first interface of the first heat exchange assembly 21, and the third sensor 33 is disposed between the other end of the series branch 10g and the second interface of the second heat exchange assembly 22. When the first heat exchange assembly 21 and the second heat exchange assembly 22 are connected in series, the first sensor 31, the second sensor 32, the third sensor 33, and the fourth sensor 34 may all detect information of the working medium.

[0156] In some embodiments of the present disclosure, the thermal management system 100 further includes a parallel selector valve 58. The parallel selector valve 58 is disposed on one side of the first interface of the first heat exchange assembly 21 and the first interface of the second heat exchange assembly 22. The parallel selector valve 58 may control the opening and closing of the first trunk pipe 10a and the second trunk pipe 10b. When the parallel selector valve 58 is turned on, the first trunk pipe 10a and the second trunk pipe 10b may be connected in parallel.

[0157] In some embodiments of the present disclosure, the first heat exchange assembly 21 is disposed on one side of the battery, and the second heat exchange assembly 22 is disposed on the other side of the battery, so that heat is exchanged on different sides of the battery, and as a result, the heat exchange efficiency of the battery can be improved.

[0158] In some embodiments of the present disclosure, the first heat exchange assembly 21 is a first heat exchange plate, and the second heat exchange assembly 22 is a second heat exchange plate. The first heat exchange plate and the second heat exchange plate are arranged on opposite sides of the battery. Compared with a design that arranges one heat exchange plate, the first heat exchange plate and the second heat exchange plate can cool or heat the opposite sides of the battery, so that the efficiency of cooling or heating the battery can be improved, and the battery can reach a suitable operating temperature more quickly, thereby improving the operating stability of the battery.

[0159] In some embodiments of the present disclosure, at least one of the first heat exchange assembly 21 and the second heat exchange assembly 22 includes a plurality of heat exchange assemblies, which are connected in parallel. By arranging the plurality of heat exchange assemblies, the area for heat exchange with the battery can be enlarged, and the heat exchange efficiency with the battery can be further improved.

[0160] In some embodiments of the present disclosure, one heat exchange assembly is disposed in an electrode heat generating area of ​​the battery and one heat exchange assembly is disposed in a non-electrode heat generating area of ​​the battery.

[0161] The controller may control the heat exchange assemblies disposed in the electrode heat generation areas of the battery to perform significant cooling and the heat exchange assemblies disposed in the non-electrode heat generation areas of the battery to perform slight cooling based on the temperature of the battery. Alternatively, the controller may control the heat exchange assemblies disposed in the electrode heat generation areas of the battery to perform cooling and the heat exchange assemblies disposed in the non-electrode heat generation areas of the battery to perform heating based on the temperature of the battery.

[0162] Referring to FIG. 1, embodiments of a thermal management system 100 operating under different conditions are described below.

[0163] In the first embodiment, only the passenger compartment is cooled.

[0164] When only the passenger compartment is cooled, the working medium flows through a working medium loop formed by the compressor 11, the on-board condenser 120, the off-board condenser 130, and the evaporator 140. In this case, the first on-off valve 51 blocks the second exhaust passage 10d, the second on-off valve 52 blocks the first exhaust passage 10c, the third on-off valve 53 opens the third passage, the fourth on-off valve 54 blocks the bypass passage 10f, the fifth on-off valve 55 opens the piping, and the sixth on-off valve 56 blocks the piping. The first electronic expansion valve 61 and the second electronic expansion valve 62 block the piping. The third electronic expansion valve 63 opens the piping and acts as a throttle. The fourth electronic expansion valve 64 blocks the piping.

[0165] The circulation path of the working medium is as follows: it flows out from the compressor 11, passes through the first pressure sensor 81, the first temperature sensor 82, the on-board condenser 120, the third on-off valve 53, the fifth on-off valve 55, the off-board condenser 130, the fourth one-way valve 44, the third electronic expansion valve 63, the evaporator 140, the third one-way valve 43, the fifth sensor 35, and the gas-liquid separator 15, and finally returns to the compressor 11.

[0166] The high-temperature, high-pressure gaseous working medium flows out of the exhaust port of the compressor 11 and through the third flow path to the on-board condenser 120. The on-board condenser 120 functions only as a pipe. The working medium continues to flow to the off-board condenser 130, where it releases heat and liquefies. Then, after being throttled and reduced in pressure by the third electronic expansion valve 63, it flows to the evaporator 140, where it absorbs heat and vaporizes. Finally, the low-temperature, low-pressure gaseous working medium flows into the intake port of the compressor 11, where it cools the passenger compartment via the evaporator 140.

[0167] In the second embodiment, only the battery is cooled, and the first heat exchange assembly 21 and the second heat exchange assembly 22 operate independently. The first heat exchange assembly 21 operates, and the second heat exchange assembly 22 does not operate.

[0168] Under the condition that only the battery is cooled, the working medium flows through a working medium loop formed by the compressor 11, the on-board condenser 120, the off-board condenser 130, and the first heat exchange assembly 21. In this case, the first on-off valve 51 blocks the second exhaust passage 10d, the second on-off valve 52 opens the first exhaust passage 10c, the third on-off valve 53 opens the third passage, the fourth on-off valve 54 blocks the bypass passage 10f, the fifth on-off valve 55 opens the piping, and the sixth on-off valve 56 blocks the piping. The first electronic expansion valve 61 opens the piping, thereby acting as a throttle. The second electronic expansion valve 62 blocks the piping. The third electronic expansion valve 63 blocks the piping. The fourth electronic expansion valve 64 blocks the piping. The parallel switching valve 58 opens the piping, and the switching valve 57 shuts off the series branch line 10g.

[0169] The working medium circulation path is as follows: it flows out of the compressor 11, passes through the first pressure sensor 81, the first temperature sensor 82, the on-board condenser 120, the third on-off valve 53, the fifth on-off valve 55, the off-board condenser 130, the fourth one-way valve 44, and the second one-way valve 42, and then flows into the first branch path. The working medium flowing into the first branch path then passes through the first electronic expansion valve 61, the second sensor 32, the first heat exchange assembly 21, the first sensor 31, the parallel switching valve 58, the second on-off valve 52, the fifth one-way valve 45, the gas-liquid separator 15, and finally returns to the compressor 11.

[0170] The high-temperature, high-pressure gaseous working medium flows out of the exhaust port of the compressor 11 and through the third flow path to the on-board condenser 120. The on-board condenser 120 functions only as a pipe. The working medium continues to flow to the off-board condenser 130, where it releases heat and liquefies. Then, after being throttled and reduced in pressure by the first electronic expansion valve 61, it flows to the first heat exchange assembly 21, where it absorbs heat and evaporates, becoming a low-temperature, low-pressure gaseous working medium that flows into the intake port of the compressor 11 and cools the battery via the first heat exchange plate.

[0171] In the third embodiment, only the battery is cooled, and the first heat exchange assembly 21 and the second heat exchange assembly 22 operate in parallel.

[0172] When only the battery is cooled, the working medium flows through a working medium loop formed by the compressor 11, the on-board condenser 120, the off-board condenser 130, and the battery heat exchange module. In this case, the first on-off valve 51 blocks the second exhaust passage 10d, the second on-off valve 52 opens the first exhaust passage 10c, the third on-off valve 53 opens the third passage, the fourth on-off valve 54 closes the bypass passage 10f, the fifth on-off valve 55 opens the piping, and the sixth on-off valve 56 closes the piping. The first electronic expansion valve 61 and the second electronic expansion valve 62 open the piping, thereby acting as throttles. The third electronic expansion valve 63 closes the piping. The fourth electronic expansion valve 64 closes the piping. The parallel selector valve 58 opens the piping, and the selector valve 57 closes the series branch passage 10g.

[0173] The circulation path of the working medium is as follows: the working medium flows out of the compressor 11, passes through the first pressure sensor 81, the first temperature sensor 82, the on-board condenser 120, the third on-off valve 53, the fifth on-off valve 55, the off-board condenser 130, the fourth one-way valve 44, and the second one-way valve 42, and then flows into the first branch path and the second branch path; the working medium flowing into the first branch path passes through the first electronic expansion valve 61, the second sensor 32, the first heat exchange valve 43, and the second one-way valve 42.

After that, the working medium passes through the second on-off valve 52, the fifth one-way valve 45, and the gas-liquid separator 15, and finally returns to the compressor 11.

[0174] The high-temperature, high-pressure gaseous working medium flows out of the exhaust port of the compressor 11 and through the third flow path to the on-board condenser 120. The on-board condenser 120 functions only as a pipe. The working medium continues to flow to the off-board condenser 130, where it releases heat and becomes liquefied. Then, after being throttled and reduced in pressure by the first electronic expansion valve 61 and the second electronic expansion valve 62, it flows to the first heat exchange assembly 21 and the second heat exchange assembly 22, where it absorbs heat and vaporizes, respectively, becoming a low-temperature, low-pressure gaseous working medium that flows into the intake port of the compressor 11 and thereby cools the battery via the first heat exchange plate and the second heat exchange plate.

[0175] In the fourth embodiment, only the battery is cooled, and the first heat exchange assembly 21 and the second heat exchange assembly 22 operate in series.

[0176] When only the battery is cooled, the working medium flows through a working medium loop formed by the compressor 11, the on-board condenser 120, the off-board condenser 130, and the battery heat exchange module.

[0178] The high-temperature, high-pressure gaseous working medium flows out of the exhaust port of the compressor 11 and through the third flow path to the on-board condenser 120. The on-board condenser 120 functions only as a pipe. The working medium continues to flow to the off-board condenser 130, where it releases heat and liquefies. Then, after being throttled and reduced in pressure by the first electronic expansion valve 61, it flows to the first heat exchange assembly 21 and the second heat exchange assembly 22, where it absorbs heat and evaporates, becoming a low-temperature, low-pressure gaseous working medium that flows into the intake port of the compressor 11 and cools the battery via the first and second heat exchange plates.

[0180] In the sixth embodiment, only the passenger compartment is heated. In addition, the outside environment may be relatively hot, and the outside condenser 130 may absorb heat from the outside environment.

[0181] Under the condition that only the passenger compartment is heated, the working medium flows through a working medium loop formed by the compressor 11, the on-board condenser 120, and the off-board condenser 130.

[0183] The high-temperature, high-pressure gaseous working medium flows out from the exhaust port of the compressor 11 and through the third exhaust passage 10e to the on-board condenser 120. In the on-board condenser 120, the working medium releases heat and becomes liquefied. Then, after being throttled and reduced in pressure by the fourth electronic expansion valve 64, it flows to the off-board condenser 130, where it exchanges heat with the outside environment, absorbs heat, and vaporizes. Finally, it becomes a low-temperature, low-pressure gaseous working medium and flows through the intake port of the compressor 11 along the bypass passage 10f, thereby heating the passenger compartment via the on-board condenser 120.

[0184] In the seventh embodiment, only the passenger compartment is heated. In addition, the outside environment is relatively cold, and the outside condenser 130 cannot absorb heat from the outside environment.

[0185] Under the condition that only the passenger compartment is heated, the working medium flows through a working medium loop formed by the compressor 11 and the on-board condenser 120.

[0187] The high-temperature, high-pressure gaseous working medium flows out of the exhaust port of the compressor 11 and through the third exhaust passage 10e to the on-board condenser 120. In the on-board condenser 120, the working medium releases heat and becomes liquefied, and then flows into the bypass passage 10f after being throttled and reduced in pressure by the fourth electronic expansion valve 64, and flows into the intake port of the compressor 11, thereby heating the passenger compartment via the on-board condenser 120.

[0188] In embodiment 8, when the ambient temperature is relatively high, only the battery is heated and the first heat exchange assembly 21 and the second heat exchange assembly 22 operate independently. The first heat exchange assembly 21 operates, but the second heat exchange assembly 22 does not.

[0189] Under the condition that only the battery is heated, the working medium flows through the working medium loop formed by the compressor 11, the first heat exchange assembly 21, and the evaporator 140.

[0195] The high-temperature, high-pressure gaseous working medium flows out of the exhaust port of the compressor 11 and through the second exhaust passage 10d to the battery heat exchange module. The working medium is liquefied by releasing heat in the first heat exchange assembly 21 and the second heat exchange assembly 22, respectively, and is throttled and reduced in pressure by the first electronic expansion valve 61, the second electronic expansion valve 62, and the third electronic expansion valve 63 before flowing into the evaporator 140, where it absorbs heat and vaporizes. Finally, the low-temperature, low-pressure gaseous working medium flows into the intake port of the compressor 11, and thereby heats the battery via the first heat exchange plate and the second heat exchange plate.

[0196] In the tenth embodiment, only the battery is heated when the ambient temperature is relatively high, and the first heat exchange assembly 21 and the second heat exchange assembly 22 operate in series.

[0197] When only the battery is heated, the working medium flows through the working medium loop formed by the compressor 11, the battery heat exchange module, and the evaporator 140.

The third electronic expansion valve 63 open the piping, thereby acting as a throttle. The fourth electronic expansion valve 64 shuts off the piping. The parallel selector valve 58 closes the piping, and the selector valve 57 opens the series branch passage 10g.

[0198] The working medium circulation path is as follows: it flows out from the compressor 11, passes through the first pressure sensor 81, the first temperature sensor 82, the first on-off valve 51, the parallel switching valve 58, the third sensor 33, the second heat exchange assembly 22, the fourth sensor 34, the first sensor 31, the first heat exchange assembly 21, the second sensor 32, the first electronic expansion valve 61, the first one-way valve 41, the sixth on-off valve 56, the third electronic expansion valve 63, the evaporator 140, the third one-way valve 43, the fifth sensor 35, and the gas-liquid separator 15, and finally returns to the compressor 11.

[0199] The high-temperature, high-pressure gaseous working medium flows out from the exhaust port of the compressor 11, through the second exhaust passage 10d to the battery heat exchange module, where it releases heat and liquefies in the first heat exchange assembly 21 and the second heat exchange assembly 22, and then flows to the evaporator 140 after being throttled and reduced in pressure by the first electronic expansion valve 61 and the third electronic expansion valve 63, where it absorbs heat and vaporizes, and finally becomes a low-temperature, low-pressure gaseous working medium and flows into the intake port of the compressor 11, thereby heating the battery through the first heat exchange plate and the second heat exchange plate.

[0200] In the eleventh embodiment, only the battery is heated when the ambient temperature is relatively low, and the first heat exchange assembly 21 and the second heat exchange assembly 22 operate in parallel.

[0201] Under the condition that only the battery is heated, the working medium flows through the working medium loop formed by the compressor 11, the battery heat exchange module, and the evaporator 140. In this case, the first on-off valve 51 opens the second exhaust passage 10d, the second on-off valve 52 closes the first exhaust passage 10c, the third on-off valve 53 closes the third passage, the fourth on-off valve 54 opens the bypass passage 10f, the fifth on-off valve 55 closes the piping, and the sixth on-off valve 56 opens the piping.

The fourth electronic expansion valve 64 performs a shutoff. The parallel selector valve 58 opens the piping, and the selector valve 57 closes the series branch passage 10g.

[0202] The working medium circulation path is as follows: the working medium flows out of the compressor 11, passes through the first pressure sensor 81, the first temperature sensor 82, and the first on-off valve 51, and then flows into the first and second branch paths. The working medium flowing into the first branch path passes through the first sensor 31, the first heat exchange assembly 21, the second sensor 32, and the first electronic expansion valve 61, and then flows out of the first branch path. The working medium flowing into the second branch path passes through the parallel switching valve 58, the third sensor 33, the second heat exchange assembly 22, the fourth sensor 34, and the second electronic expansion valve 62, and then flows out of the second branch path. After being mixed with the working medium flowing out of the first branch path, the working medium flows through the first one-way valve 41, the sixth on-off valve 56, the fourth on-off valve 54, the fifth sensor 35, and the gas-liquid separator 15, and finally returns to the compressor 11.

[0203] The high-temperature, high-pressure gaseous working medium flows out of the exhaust port of the compressor 11 and into the battery heat exchange module through the second exhaust passage 10d. The working medium releases heat and liquefies in the first heat exchange assembly 21 and the second heat exchange assembly 22, respectively, and then flows into the compressor 11 after being throttled and reduced in pressure by the first electronic expansion valve 61, the second electronic expansion valve 62, and the third electronic expansion valve 63. However, the ambient temperature is relatively low. The working medium naturally exchanges heat during the flow process, and finally becomes a low-temperature, low-pressure gaseous working medium. This working medium flows into the intake port of the compressor 11, thereby heating the battery through the first and second heat exchange plates.

[0204] In the case of a condition where the ambient temperature is relatively high and both the passenger compartment and the battery pack are heated, the embodiment 12 is actually the simultaneous operation of the embodiment 6 and any one of the embodiments 8 to 10.

[0205] The above embodiments are merely for the convenience and simplification of the description of the present disclosure and are not intended to suggest or imply that the thermal management system 100 can only operate based on the circumstances shown in the embodiments under certain conditions, and therefore should not be understood as limitations on the present disclosure.

[0206] In some embodiments of the present disclosure, the thermal management system further includes a dynamic thermal management subsystem 200, which includes a heat exchanger 71 and a coolant circulation system. The heat exchanger 71 includes a first flow path and a second flow path. The first flow path is connected to the coolant circulation system, and one end of the second flow path is connected to at least one of the first main pipe 10a and the second main pipe 10b.

[0207] The thermal management system 100 further includes an air conditioning circulation loop 101 that further includes a heating branch. One of the first trunk pipe 10a and the second trunk pipe 10b is connected to a second flow path. The other of the first trunk pipe 10a and the second trunk pipe 10b is connected in parallel to the heating branch. The controller is configured to control at least one of the heating branch, the first trunk pipe 10a, and the second trunk pipe 10b to exchange heat.

[0208] The coolant flows through a first flow path and the working medium flows through a second flow path, and both the first flow path and the second flow path are located within a heat exchanger 71, and the first flow path and the second flow path may exchange heat with each other. If the temperature of the coolant flowing through the second flow path is higher than the temperature of the working medium flowing through the first flow path, the working medium absorbs heat as it flows through the heat exchanger 71. If the temperature of the coolant flowing through the second flow path is lower than the temperature of the working medium flowing through the first flow path, the working medium releases heat as it flows through the heat exchanger 71.

[0209] The coolant circulation system may exchange heat generated by the dynamic thermal management subsystem 200 with the working medium, thereby heating or cooling the working medium by using the heat generated by the dynamic thermal management subsystem 200 to assist the battery heat exchange module in exchanging heat with the battery.

[0210] In some embodiments of the present disclosure, as shown in FIG. 2, a dynamic thermal management subsystem 200 includes at least one of a high-pressure thermal management subsystem 201 and an engine thermal management subsystem 202 .

[0211] The high-pressure thermal management subsystem 201 may exchange heat with the air conditioning circulation loop 101, the engine thermal management subsystem 202 may exchange heat with the air conditioning circulation loop 101, or both the high-pressure thermal management subsystem 201 and the engine thermal management subsystem 202 may exchange heat with the air conditioning circulation loop 101.

[0212] In some embodiments of the present disclosure, the thermal management system further includes a high-pressure thermal management subsystem 201, which includes a heat exchanger 71 and a coolant circulation system. The heat exchanger 71 includes a first flow path and a second flow path. The first flow path is connected to the coolant circulation system. One end of the second flow path selectively communicates with the second end and the first heat exchanger 12, and the other end of the second flow path is connected to the heat exchanger 71.

[0213] In some embodiments of the present disclosure, the high-pressure thermal management subsystem 201 further includes a charging and power distribution / motor assembly 72 and a first radiator 73. The charging and power distribution / motor assembly 72 exchanges heat with the vehicle's motor and electrical controls. The charging and power distribution / motor assembly 72 is connected between the coolant circulation system and the first radiator 73. The first radiator 73 is adapted to exchange heat with the exterior environment.

[0214] In some embodiments of the present disclosure, the high-pressure thermal management subsystem 201 further includes a switching valve group 74. The switching valve group 74 is connected to two ends of the circulation loop, the charging and distribution / motor assembly 72 and the first radiator 73, respectively. The switching valve group 74 is operated to switch the high-pressure thermal management subsystem 201 between different conditions. The switching valve group 74 is a three-way valve.

[0215] The switching valve group 74 may control the direction of the coolant, may heat the working medium with heat generated by the vehicle's motor and electrical controls, or may dissipate heat generated by the vehicle's motor and electrical controls to the outside of the vehicle via the first radiator 73.

[0216] In some embodiments of the present disclosure, the high-pressure thermal management system 100 further includes a water pump 75. The water pump 75 is disposed between the charging and power distribution / motor assembly 72 and the heat exchanger 71. The water pump 75 is constructed such that coolant is pumped from the charging and power distribution / motor assembly 72 to the heat exchanger 71.

[0217] High-pressure thermal management subsystem 201 has a first condition. Under the first condition, charging and distribution / motor assembly 72 and the second flow path form a first loop. Coolant flowing out of charging and distribution / motor assembly 72 flows to heat exchanger 71 under the action of water pump 75. The coolant exchanges heat with the working medium on the first flow path on the second flow path of heat exchanger 71, then returns to charging and distribution / motor assembly 72 to exchange heat with the vehicle's motor and electrical controls.

[0218] If the working medium has a heat absorption requirement for circulation and reverse flow and the high-pressure thermal management subsystem 201 does not have a heat dissipation requirement, the high-pressure thermal management subsystem 201 may operate under the first condition. Hot coolant exiting the charging and power distribution / motor assembly 72 enters the second flow path and exchanges heat with the cold working medium flowing through the first flow path, transferring heat generated by the vehicle's motor and electrical controls to the circulating and reverse flowing working medium. The heat generated by the vehicle's motor and electrical controls is effectively used, thereby improving the heating capacity of the thermal management system 100 and reducing the energy consumption of the thermal management system 100.

[0219] The high-pressure thermal management subsystem 201 further has a second condition. Under the second condition, the charging and power distribution / motor assembly 72, the first radiator 73, and the second flow path form a second loop. The coolant flowing out of the charging and power distribution / motor assembly 72 flows to the heat exchanger 71 under the action of the water pump 75. The coolant exchanges heat with the working medium in the first flow path in the second flow path of the heat exchanger 71 and then flows to the first radiator 73. After exchanging heat in the first radiator 73, the coolant returns to the charging and power distribution / motor assembly 72 and exchanges heat with the vehicle's motor and electrical controls.

[0220] If the working medium has a heat absorption requirement for circulation and reverse flow, and the high-pressure thermal management subsystem 201 has a heat dissipation requirement, and the heat dissipation requirement of the high-pressure thermal management subsystem 201 is higher than the heat absorption requirement for circulation and reverse flow of the working medium, the high-pressure thermal management subsystem 201 may operate under a second condition. The high-temperature coolant flowing out of the charging and power distribution / motor assembly 72 flows into the second flow path and exchanges heat with the low-temperature working medium flowing through the first flow path, transferring heat generated by the vehicle's motor and electrical controls to the circulating and reverse flowing working medium. However, the coolant's temperature remains relatively high even after the heat exchange. Therefore, the coolant flows to the first radiator 73 to exchange heat with the outside environment again and dissipate the heat. The heat generated by the vehicle's motor and electrical controls is effectively used, thereby improving the heating capacity of the thermal management system 100 and reducing its energy consumption.

[0221] Additionally, if the working medium has a heat absorption requirement during circulation and counterflow, and the heat generated by the high-pressure thermal management subsystem 201 is insufficient and the coolant temperature is lower than the temperature of the outside environment, the high-pressure thermal management subsystem 201 may alternatively operate under a second condition. The coolant exchanges heat with the outside environment in the first radiator 73 to raise the coolant temperature. The coolant then flows through the circulation loop to the charge and power distribution / motor assembly 72 and the heat exchanger 71, exchanging heat with the lower temperature working medium flowing through the first flow path, thereby transferring heat from the outside environment to the circulating and counterflow working medium and the high-pressure thermal management subsystem 201. The heat may be used effectively, thereby improving the heating capacity of the thermal management system 100 and reducing the energy consumption of the thermal management system 100.

[0222] The high-pressure thermal management subsystem 201 further includes a combined condition. Under the combined condition, circulation is performed in both the first and second loops. The coolant flowing out of the charging and power distribution / motor assembly 72 flows to the third heat exchanger 14 under the action of the water pump 75. After the coolant exchanges heat with the working medium on the first flow path in the second flow path of the third heat exchanger 14, a portion of the coolant returns directly to the charging and power distribution / motor assembly 72 to exchange heat with the vehicle's motor and electrical controls, and another portion of the coolant flows to the first radiator 73. After exchanging heat in the first radiator 73, the coolant returns to the charging and power distribution / motor assembly 72 to exchange heat with the vehicle's motor and electrical controls.

[0223] If the working medium has a heat absorption requirement during circulation and counterflow, and the high-pressure thermal management subsystem 201 has a heat dissipation requirement, and the heat absorption requirement of the working medium during circulation and counterflow is higher than the heat dissipation requirement of the high-pressure thermal management subsystem 201, the high-pressure thermal management subsystem 201 may operate under a combined condition.

[0224] The hot coolant exiting the charging and power distribution / motor assembly 72 flows into the second flow path and exchanges heat with the cold working medium flowing through the first flow path, transferring heat generated by the vehicle's motor and electrical controls to the circulating and counter-flowing working medium. A portion of the coolant returns to the charging and power distribution / motor assembly 72, while another portion flows to the radiator 73, where it exchanges heat with the outside environment again to dissipate the heat. The heat generated by the vehicle's motor and electrical controls is effectively used, thereby improving the heating capacity of the thermal management system 100 and reducing its energy consumption.

[0225] For example, the high-pressure thermal management subsystem 201 may have a first condition, a second condition, and a combined condition. Under the first condition, the second condition, and the combined condition, the circulating and counterflowing coolant heats the circulating and counterflowing working medium, respectively. Thus, the thermal management system 100 may operate under different conditions and in conjunction with the different conditions of the high-pressure thermal management subsystem 201.

[0226] For example, if only the condition in which the passenger compartment is heated is used, that condition may be interconnected with the first condition, the second condition, and the combined condition of the high pressure thermal management subsystem 201 .

[0227] In some embodiments of the present disclosure, the thermal management system further includes an engine thermal management subsystem 202, which includes a fifth heat exchanger 76 and a coolant circulation system. The fifth heat exchanger 76 includes a third flow path and a fourth flow path. The third flow path is connected to the coolant circulation system. One end of the fourth flow path selectively communicates with the second end b and the first heat exchanger 12, and the other end of the fourth flow path is connected to the third heat exchanger 14.

[0228] In some embodiments of the present disclosure, the engine thermal management subsystem 202 further includes a motor assembly 77 and a second radiator 78. The motor assembly 77 is adapted to exchange heat with the vehicle's motor. The motor assembly 77 is connected between the coolant circulation system and the second radiator 78. The second radiator 78 is adapted to exchange heat with the outside environment.

[0229] A vehicle 1000 according to one embodiment of the present disclosure includes a thermal management system 100 according to any one of the previous embodiments.

[0230] Based on the vehicle 1000 according to this embodiment of the present disclosure, the aforementioned thermal management system 100 is arranged, which can reduce the number of maintenance and battery replacements, improve the charging efficiency and convenience of the vehicle, and facilitate the appropriate layout of the vehicle.

[0231] While embodiments of the present disclosure have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principle and spirit of the present disclosure, the scope of which is as defined by the appended claims and their equivalents.
