Description

Technical Field

[0001] This invention relates to the field of charging and battery swapping stations, and specifically provides a thermal management system for charging and battery swapping stations. Background Technology

[0002] With the popularization of new energy vehicles, the market demand for charging and battery swapping products is growing rapidly, and research on related technologies has received significant attention. To improve charging speed, liquid cooling technology has been introduced into charging modules, charging guns, and rechargeable batteries to reduce the risk of thermal runaway during rapid charging. The cooling unit for liquid-cooled charging guns is located inside the charging station, and its noise and space requirements are difficult to control, often resulting in high noise levels and large size. Furthermore, the coolant requirements of charging modules (AC / DC and DC / DC modules) differ from those of the batteries in the battery swapping station, making it difficult to achieve a balance using a single coolant.

[0003] In the market, to meet the different cooling needs of charging modules and batteries within battery swapping stations, patent publication number CN114056147A describes controlling the operation of relevant valves (such as three-way valves and regulating valves corresponding to the power battery section / station air conditioning system) by adjusting their on / off states and specific opening degrees, as well as pump operating parameters, thereby achieving effective thermal management. However, this method requires valves and control devices to operate them, resulting in high production and control costs, and limited effectiveness.

[0004] Accordingly, there is a need in the field for a thermal management system for charging and battery swapping stations to address the aforementioned issues. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, and to address the issue that existing dual-temperature water cooling technologies require valves and control devices for control, which are costly and have limited effectiveness.

[0006] This invention provides a thermal management system for a charging and battery swapping station, including a cooling cycle, a battery compartment cooling cycle, and a charging cooling cycle;

[0007] The refrigeration cycle includes an evaporator, the battery compartment cooling cycle includes a first heat exchange component, the charging cooling cycle includes a second heat exchange component, and the evaporator, the first heat exchange component, and the second heat exchange component are circulatedly connected through a circulating heat exchange pipeline.

[0008] The refrigeration cycle is configured to provide cooling to the first heat exchange component and the second heat exchange component.

[0009] The battery compartment cooling cycle is configured to at least utilize the cooling capacity of the first heat exchange component for cooling the battery within the battery compartment.

[0010] The charging cooling cycle is configured to at least utilize the cold energy in the second heat exchange component for cooling the charging module and / or the charging pile.

[0011] With the above technical solution, the refrigeration cycle provides cooling to the first heat exchange component and the second heat exchange component, so that the battery compartment cooling cycle and the charging cooling cycle can independently cool the battery and charging module and / or charging pile. This enables a separate refrigeration cycle to cool different locations at different temperatures, achieving dual water temperature requirements without the need for valves and control devices, thus saving production and control costs.

[0012] In a specific embodiment of the above-mentioned charging and swapping heat management system, the refrigeration cycle includes a compressor, a condenser, a fan, a throttling element, and an evaporator; the evaporator has a refrigerant flow channel and a first heat exchange flow channel formed inside, which can exchange heat with each other; the compressor, the condenser, the throttling element, and the refrigerant flow channel are circulatedly connected through refrigerant pipelines; the first heat exchange flow channel is circulatedly connected to the first heat exchange component and the second heat exchange component.

[0013] In the specific implementation of the above-mentioned charging and swapping heating management system, the number of fans is two.

[0014] By employing the above technical solution, the two fans can regulate the heat dissipation, improving control precision. Furthermore, the dual-fan configuration ensures overall stability; even if one fan fails, it will not affect the overall operation.

[0015] In the specific implementation of the above-mentioned charging and swapping heating management system, there are two compressors and two throttling elements. Each compressor and its corresponding throttling element are independently connected to the condenser and the refrigerant channel through a refrigerant pipeline.

[0016] With the above technical solution, under normal operating conditions, operating a single compressor and throttling element is sufficient to meet the cooling capacity requirements, achieving low cost and energy saving. Under special operating conditions, two compressors can be operated simultaneously to meet high cooling capacity requirements. The use of two compression circuits also provides high reliability with one in operation and one on standby.

[0017] In a specific implementation of the above-mentioned charging and swapping heat management system, the first heat exchange channel, the first heat exchange component, and the second heat exchange component are connected in sequence.

[0018] When the above technical solution is adopted, after the medium in the evaporator in the above cycle is cooled, it first passes through the first heat exchange component and then through the second heat exchange component, thereby ensuring that the medium temperature in the first heat exchange component is lower and that the medium temperature in the battery compartment cooling cycle is lower.

[0019] In a specific implementation of the above-mentioned charging and heat exchange management system, a first water pump is connected to the circulating heat exchange pipeline.

[0020] With the above technical solution, the circulation of the medium in the circulating heat exchange pipeline is made smoother by the first water pump.

[0021] In a specific implementation of the above-mentioned charging and swapping heat management system, the first heat exchange component is a first water tank.

[0022] In a specific embodiment of the above-mentioned charging and swapping thermal management system, the battery compartment cooling cycle further includes a battery compartment cooling pipeline and a second water pump. The battery compartment cooling pipeline is circulated in connection with the first water tank, and the second water pump is installed in the battery compartment cooling pipeline.

[0023] With the above technical solution adopted, the circulation of the medium in the battery compartment cooling pipe is made smoother by the second water pump.

[0024] In a specific embodiment of the above-mentioned charging and swapping thermal management system, there are multiple battery compartment cooling pipes, and each battery compartment cooling pipe is equipped with a second water pump.

[0025] In a specific embodiment of the above-mentioned charging and swapping heat management system, the second heat exchange component is a first heat exchanger. The first heat exchanger has a second heat exchange channel and a first cooling channel that can exchange heat with each other. The second heat exchange channel is circulatedly connected to the evaporator and the first heat exchange component.

[0026] In a specific embodiment of the above-mentioned charging and swapping thermal management system, the charging cooling cycle further includes a second water tank, a charging module cooling pipeline, and a third water pump. The second water tank, the first cooling channel, and the charging module cooling pipeline are cyclically connected, and the third water pump is installed in the charging module cooling pipeline.

[0027] When the above technical solution is adopted, the cooling energy is carried to the second water tank through the first cooling channel, and the third water pump causes the medium in the second water tank to circulate in the charging module cooling pipe, thereby cooling the battery charging module.

[0028] In a specific embodiment of the above-mentioned charging and swapping heat management system, the charging cooling cycle further includes a fourth water pump and a charging pile heat exchange pipeline. The second water tank, the first cooling channel and the charging pile heat exchange pipeline are circulated and connected. The fourth water pump is installed in the charging pile heat exchange pipeline.

[0029] When the above technical solution is adopted, the fourth water pump circulates the medium in the second water tank into the heat exchange pipeline of the charging pile, which facilitates the cooling of the charging pile.

[0030] In a specific embodiment of the above-mentioned charging and swapping heat management system, the charging cooling cycle further includes a second heat exchanger, a fifth water pump, and a charging pile cooling pipeline. The second heat exchanger has a third heat exchange channel and a second cooling channel that can exchange heat with each other. The second water tank, the first cooling channel, the charging pile heat exchange pipeline, and the three heat exchange channels are circulated and connected. The charging pile cooling pipeline and the second cooling channel are circulated and connected. The fifth water pump is installed in the charging pile cooling pipeline.

[0031] With the above technical solution, a second heat exchanger is used to transfer the cold energy in the heat exchange pipeline of the charging pile to the cooling pipeline of the charging pile. Then, a fifth water pump is used to circulate the medium in the cooling pipeline of the charging pile, thereby cooling the charging pile. This allows the charging pile to have independent circulation cooling control, which is beneficial to the individual cooling design of the charging pile and improves the cooling safety of the charging pile.

[0032] In a specific implementation of the above-mentioned charging and swapping thermal management system, the fifth water pump is communicatively connected to the controller of the charging pile of the charging and swapping station.

[0033] When the above technical solution is adopted, the fifth water pump is connected to the controller of the charging pile. The controller can control the start and stop of the fifth water pump to achieve rapid coordination of charging and cooling, as well as high-efficiency operation.

[0034] In a specific embodiment of the above-mentioned charging and swapping heating management system, an electric heater is installed in the first water tank.

[0035] With the above technical solution, in low-temperature environments, an electric heater can be used to heat the medium in the first water tank, avoiding the problem of insufficient heat during heat exchange in winter.

[0036] The present invention also provides a charging and battery swapping station, including the above-described charging and battery swapping station thermal management system.

[0037] With the above technical solution, the charging and battery swapping station can control different temperatures at different locations, while saving the traditional valves used to control the temperature at different locations. This allows the cooling capacity to be utilized to the maximum extent and reduces the energy consumption of the charging and battery swapping station.

Detailed Implementation

[0066] Preferred embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, a thermostatic expansion valve is used as the throttling element in this application; other throttling elements, such as capillary tubes or electronic expansion valves, can also be used.

[0067] It should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "set up," "connection," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or other type of connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. Furthermore, the terms "first," "second," "third," "fourth," and "fifth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0068] It should also be understood that the terms "upper," "inner," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, "a plurality of" in this application means at least two.

[0069] like Figure 1 As shown, to address the issue of high costs associated with dual-temperature water cooling systems requiring valves and control devices, this invention provides a thermal management system for a charging / swapping station, comprising a refrigeration cycle 1, a battery compartment cooling cycle 4, and a charging cooling cycle 5. The refrigeration cycle includes an evaporator 15, the battery compartment cooling cycle 4 includes a first heat exchange component 44, and the charging cooling cycle 5 includes a second heat exchange component 59. The evaporator 15, the first heat exchange component 44, and the second heat exchange component 59 are circulated and connected via a circulating heat exchange pipeline 2. The refrigeration cycle 1 is configured to provide cooling to both the first heat exchange component 44 and the second heat exchange component 59; the battery compartment cooling cycle 4 is configured to utilize at least the cooling capacity of the first heat exchange component 44 for cooling the batteries within the battery compartment 42; and the charging cooling cycle 5 is configured to utilize at least the cooling capacity of the second heat exchange component 59 for cooling the charging module 53 and / or the charging pile 57.

[0070] Thus, with the above technical solution adopted, the cooling cycle 1 provides cooling capacity to the first heat exchange component 44 and the second heat exchange component 59, so that the battery compartment cooling cycle 4 and the charging cooling cycle 5 can independently cool the battery and charging module 53 and / or charging pile 57, thereby realizing that the individual cooling cycle 1 can cool different locations at different temperatures. Dual water temperature can be achieved without the need for valves and control devices, saving production costs.

[0071] In a preferred embodiment of the above-described charging and swapping heat management system, the refrigeration cycle 1 includes two compressors 11, a condenser 12, two fans 13, two throttling elements 14, and an evaporator 15. The evaporator 15 has internal refrigerant channels and a first heat exchange channel for heat exchange. The outlet of one compressor 11 is connected to the inlet of the condenser 12, and the outlet of the condenser 12 is connected to the inlet of a throttling element 14. The outlet of the throttling element 14 is connected to the inlet of the refrigerant channel, and the outlet of the refrigerant channel is connected to the inlet of the compressor 11, forming a complete cycle. The connection between adjacent components is achieved through a refrigerant pipeline 16. The other compressor 11 and its corresponding throttling element 14 are independently connected to the condenser 12 and the refrigerant channel via the refrigerant pipeline 16. The first heat exchange channel is connected to the first heat exchange component 44 and the second heat exchange component 59. Both fans 13 are located on one side of the condenser 12.

[0072] Thus, the two fans 13 can regulate the heat dissipation, improving control precision. The dual-fan configuration also ensures overall stability; even if one fan 13 fails, it does not affect overall operation. While multiple fans 13 are possible, two are the optimal choice. The fans 13 dissipate heat from the condenser 12, and those skilled in the art can select different numbers of fans 13 according to specific needs. Under normal operating conditions, operating a single compressor 11 and throttling element 14 is sufficient to meet cooling requirements, achieving low cost and energy saving. Under special conditions, two compressors can be operated simultaneously to meet high cooling capacity demands. Furthermore, the use of two compression circuits provides high reliability with one in operation and one in standby.

[0073] It should be noted that the connection order between the components in the refrigeration cycle is not mandatory. The connection method described above is the optimal connection method. Those skilled in the art can choose the connection order between the components based on the specific application scenario, or they can choose not to use the connection order described above.

[0074] It should be further explained that the function of refrigeration cycle 1 is to provide cooling capacity. The components included in refrigeration cycle 1 are only the most basic components that make up refrigeration cycle 1. Those skilled in the art can add valves, sensors, etc. to refrigeration cycle 1 according to the needs of actual applications. The throttling element here is a thermostatic expansion valve, but other valves with throttling effects, such as capillary tubes or electronic expansion valves, can also be used.

[0075] It should also be noted that the optimal choice is to have two compressors 11 and two throttling elements 14, mainly to increase overall reliability. Of course, those skilled in the art can choose more compressors 11 and throttling elements 14 to further increase overall reliability, or they can use only one compressor 11 and one throttling element 14.

[0076] In the preferred embodiment of the above-described charging and swapping thermal management system, the first heat exchange channel, the first heat exchange component 44, and the second heat exchange component 59 are sequentially connected, and a first water pump 21 is connected to the circulating heat exchange pipeline 2. The first water pump 21 is located on the circulating heat exchange pipeline 2 between the first heat exchange component 44 and the second heat exchange component 59, and ethylene glycol coolant is contained in the circulating heat exchange pipeline 2 for the transfer of cooling capacity. Thus, after the medium in the evaporator 15 is cooled in the above-described cycle, it first passes through the first heat exchange component 44 and then through the second heat exchange component 59, thereby ensuring that the medium temperature in the first heat exchange component 44 is lower, further ensuring that the medium temperature in the battery compartment cooling cycle 4 is lower. The charging cooling cycle 5, which is connected to the second heat exchange component 59, typically requires a higher temperature; even the medium after passing through the first heat exchange component 44 can cool the second heat exchange component 59, further saving energy. The first water pump 21 makes the circulation of the medium in the circulating heat exchange pipeline 2 smoother.

[0077] It should be noted that the order in which the first heat exchange channel, the first heat exchange component 44, the first water pump 21, and the second heat exchange component 59 are arranged is not mandatory. The above-described connection method is the optimal connection method, and those skilled in the art can choose the connection order between these components based on specific application scenarios. Furthermore, the inclusion of the first water pump 21 is not mandatory. Those skilled in the art can choose whether to include the first water pump 21 and the specific number of first water pumps 21 based on specific application scenarios. Of course, it is also possible to omit the first water pump 21 or include multiple first water pumps 21.

[0078] In a preferred embodiment of the above-described charging / swapping thermal management system, the first heat exchange component 44 is a first water tank, which stores ethylene glycol coolant. The battery compartment cooling circulation 4 also includes a battery compartment cooling pipe 43 and a second water pump 41. The battery compartment cooling pipe 43 is circulated and connected to the first water tank, and the second water pump 41 is installed on the battery compartment cooling pipe 43. In this application, there are two battery compartment cooling pipes 43, both of which are circulated and connected to the first water tank. Each battery compartment cooling pipe 43 is equipped with a second water pump 41. One battery compartment cooling pipe 43 can simultaneously cool five battery compartments 42, and the battery compartments 42 are connected to the battery compartment cooling pipe 43 in parallel. Thus, the cooling energy from the first water tank cools the battery compartments 42, and the second water pump 41 makes the circulation of the medium within the battery compartment cooling pipe 43 smoother.

[0079] It should be noted that there are multiple battery compartment cooling cycles 4. Those skilled in the art can select the number of battery compartment cooling pipes 43 according to the required number of battery compartments 42 and the cooling capacity of cooling cycle 1. In this embodiment, the optimal selection is two battery compartment cooling pipes 43. Simultaneously, the same battery compartment cooling pipe 43 can cool multiple battery compartments 42 at the same time. Those skilled in the art can select the number of battery compartments 42 on the same battery compartment cooling pipe 43 according to the required number. In this embodiment, the optimal selection is five battery compartments 42 on the same battery compartment cooling pipe 43.

[0080] It should be further noted that the setting of the second water pump 41 is not mandatory. Those skilled in the art can choose whether to set the second water pump 41 and the specific number of the second water pump 41 based on the specific application scenario. Of course, it is also possible not to set the second water pump 41 or to set multiple second water pumps 41.

[0081] Furthermore, it should be noted that although the above embodiment is described with the first heat exchange component 44 as an example of a first water tank, this is only a preferred embodiment. Those skilled in the art can replace the specific form of the first heat exchange component 44, as long as it can absorb the cold energy of the circulating heat exchange pipeline 2. For example, the first heat exchange component 44 can also be a heat exchanger, specifically a plate heat exchanger or a shell-and-tube heat exchanger, etc.

[0082] In a preferred embodiment of the above-described charging and swapping thermal management system, the second heat exchange component 59 is a first heat exchanger. The first heat exchanger has a second heat exchange channel and a first cooling channel that can exchange heat with each other. The second heat exchange channel is circulated and connected to the evaporator 15 and the first heat exchange component 44. The first heat exchanger can be a plate heat exchanger or a shell-and-tube heat exchanger, etc. The charging cooling cycle 5 also includes a second water tank 51, a charging module cooling pipe 54, and a third water pump 52. The outlet of the second water tank 51 is connected to the inlet of the third water pump 52, the outlet of the third water pump 52 is connected to the inlet of the first cooling channel, and the outlet of the first cooling channel is connected to the inlet of the second water tank. Adjacent components are connected by the charging module cooling pipe 54. The charging module cooling pipe 54 between the outlet of the third water pump 52 and the inlet of the first cooling channel passes through the battery charging module 53 to cool the battery charging module 53. When the above technical solution is adopted, the cooling energy is brought to the second water tank 51 through the first cooling channel, and the third water pump 52 causes the medium in the second water tank 51 to circulate in the charging module cooling pipe 54, thereby cooling the battery charging module 53.

[0083] It should be noted that the interconnected relationship between the components used to cool the battery charging module 53 can be adjusted by those skilled in the art according to specific usage scenarios to suit different applications. Furthermore, the inclusion of a third water pump 52 is not mandatory. Those skilled in the art can choose whether to include a third water pump 52 and the specific number of third water pumps 52 based on specific application scenarios. Alternatively, a third water pump 52 may be omitted or multiple third water pumps 52 may be included.

[0084] It should also be noted that the above-mentioned charging cooling cycle 5 is the simplest structure for cooling the battery charging module 53. Those skilled in the art can add corresponding valves or filters to the charging module cooling pipe 54 according to the actual working needs.

[0085] Furthermore, it should be noted that although the above embodiment is described with the second heat exchange component 59 as an example of the first heat exchanger, this is only a preferred embodiment. Those skilled in the art can replace the specific form of the second heat exchange component 59, as long as it can absorb the cooling capacity of the circulating heat exchange pipeline 2. For example, the second heat exchange component 59 can also be a water tank, or the second heat exchange component 59 can be omitted, and the circulating heat exchange pipeline 2 can be directly connected to the second water tank 51.

[0086] In a preferred embodiment of the charging and swapping heat management system described above, the charging cooling cycle 5 further includes a fourth water pump 56, a second heat exchanger 55, and a charging pile heat exchange pipeline 571. The second heat exchanger 55 has a third heat exchange channel and a second cooling channel that can exchange heat with each other. The outlet of the second water tank 51 is connected to the inlet of the fourth water pump 56, the outlet of the fourth water pump 56 is connected to the inlet of the third heat exchange channel, the outlet of the third heat exchange channel is connected to the inlet of the first cooling channel, and the outlet of the first cooling channel is connected to the inlet of the second water tank 51. Adjacent components are connected via the charging pile heat exchange pipeline 571. Thus, the fourth water pump 56 circulates the medium in the second water tank 51 into the charging pile heat exchange pipeline 571. The medium in the second water tank 51 is selected as ethylene glycol coolant. Here, ethylene glycol coolant is just one type of cooling medium; other cooling media may include propylene glycol coolant, water, or silicone oil.

[0087] It should be noted that the cyclical connection between the above-mentioned components can be adjusted by those skilled in the art according to specific usage scenarios to suit different applications. Furthermore, the inclusion of a fourth water pump 56 is not mandatory. Those skilled in the art can choose whether to include a fourth water pump 56 and the specific number of fourth water pumps 56 based on specific application scenarios. Of course, it is also possible to omit the fourth water pump 56 or include multiple fourth water pumps 56.

[0088] In a preferred embodiment of the charging and swapping thermal management system described above, the charging cooling cycle 5 further includes a fifth water pump 58 and a charging pile cooling pipe 572. The outlet of the second cooling channel is connected to the inlet of the fifth water pump 58, and the outlet of the fifth water pump 58 is connected to the inlet of the second cooling channel. Adjacent components are connected via the charging pile cooling pipe 572. The charging pile cooling pipe 572 between the outlet of the fifth water pump 58 and the inlet of the second cooling channel is used to cool the charging pile 57. Thus, the second heat exchanger 55 transfers the cold energy from the charging pile heat exchange pipe 571 to the charging pile cooling pipe 572, and the fifth water pump 58 circulates the medium within the charging pile cooling pipe 572, thereby cooling the charging pile 57. Simultaneously, the charging pile has independent circulating cooling control, which is beneficial for the individual cooling design of the charging pile and improves the cooling safety of the charging pile. The cooling medium in the charging pile cooling pipe 572 is physically isolated, and a medium different from that in other circulating pipes, such as silicone oil, can be filled into the charging pile cooling pipe 57. Furthermore, the second heat exchanger 55 here can be a plate heat exchanger. The second heat exchanger 55, the fifth water pump 58 and the charging pile cooling pipe 572 are installed on the charging pile 57 to facilitate heat dissipation of the charging pile 57.

[0089] It should be noted that the cyclical connection between the above-mentioned components can be adjusted by those skilled in the art according to specific usage scenarios to suit different applications. Furthermore, the inclusion of a fifth water pump 58 is not mandatory. Those skilled in the art can choose whether to include a fifth water pump 58 and the specific number of fifth water pumps 58 based on specific application scenarios. Of course, it is also possible to omit the fifth water pump 58 or include multiple fifth water pumps 58.

[0090] It should also be noted that the above-described charging cooling cycle 5 is the simplest structure for achieving heat transfer. Those skilled in the art can add appropriate valves or filters to the charging cooling cycle 5 according to actual working needs. Silicone oil can also be replaced with other coolants, such as water or ethylene glycol solution.

[0091] It should be further noted that the installation of the second heat exchanger 55 is not mandatory. Those skilled in the art can choose whether to install the second heat exchanger 55 based on the specific application scenario, or of course, the second heat exchanger 55 can be omitted. For example, the charging pile heat exchange pipeline 571 can be used to directly dissipate heat from the charging pile, or the charging pile cooling pipeline 572 can be used to dissipate heat from both the charging pile battery charging module 53 and the charging pile 57.

[0092] In the preferred embodiment of the above-described charging and battery swapping thermal management system, the fifth water pump 58 is communicatively connected to the controller of the charging pile 57 of the charging and battery swapping station. Thus, the controller can control the start and stop of the fifth water pump 58, achieving rapid coordination between charging and cooling, and high-efficiency operation.

[0093] It should be noted that the use of a controller is not mandatory. Those skilled in the art can choose whether to use a controller and the specific structure of the controller based on the specific use case. Of course, it is also possible not to use a controller.

[0094] In a preferred embodiment of the above-described charging and heat exchange management system, an electric heater 45 is installed inside the first water tank. Thus, in low-temperature environments, the electric heater 45 can be used to heat the medium in the first water tank, avoiding the problem of insufficient heat during heat exchange in winter.

[0095] The following is combined with Figure 1 The specific operation mode of the charging station thermal management system provided by the present invention is described below. In a high-temperature environment, the battery and charging pile 57 in the battery swapping station are started charging, and the charging module 53 starts operating. At this time, it is necessary to cool down the battery, charging pile 57, and charging module 53. Specifically, the compressor 11, condenser 12, fan 13, throttling element 14, and evaporator 15 can provide cooling and transfer the cooling energy to the second heat exchange channel of the first water tank and the first heat exchanger. The cooling medium first passes through the first water tank and then through the second heat exchange channel. The first water tank can cool the battery through the battery compartment cooling pipe 43. The second heat exchange channel can transfer the cooling energy to the first cooling channel. The first cooling channel, the second water tank 51, and the charging module cooling pipe 54 are circulated and connected, thereby cooling the charging module 53. The second water tank 51 is circulatedly connected to the heat exchange pipeline 571 of the charging pile. The second heat exchanger 55 is used to transfer the cold energy in the heat exchange pipeline 571 of the charging pile to the cooling pipeline 572 of the charging pile. Then, the fifth water pump 58 is used to circulate the medium in the cooling pipeline 572 of the charging pile, thereby cooling the charging pile 57.

[0096] Another possible operating mode, in a high-temperature environment, when charging of the battery and charging pile 57 in the charging station begins and the charging module 53 starts operating, the medium in the first water tank first cools the battery through the battery compartment cooling pipe 43, and raises the temperature of the medium in the first water tank. Simultaneously, the second water tank 51 is circulated and connected to the charging module cooling pipe 54 and the charging pile cooling pipe 572, respectively, cooling the charging module 53 and the charging pile 57 while raising the temperature of the medium in the second water tank 51. Furthermore, through the first heat exchanger, the temperature in the first water tank and the temperature in the second water tank 51 tend to be equal. When the temperature in the first water tank exceeds the temperature capable of cooling the battery, the cooling cycle 1 is activated to cool the first water tank and the first heat exchanger.

[0097] Another possible operating mode is that, in low-temperature environments, the first water tank can maintain the temperature required for battery charging using the waste heat from the electric heater 45 and the charging module 53. Specifically, firstly, the heat generated by the battery during charging can be circulated through the battery compartment cooling cycle 4; secondly, the heat generated by the charging module 53 and the charging pile 57 is conducted to the second water tank 51 through the charging module cooling pipe 54 and the charging pile heat exchange pipe 571, and then, through the connection between the first heat exchanger and the first water tank, the temperature in the second water tank 51 can be transferred to the first water tank, which is equivalent to transferring the temperature in the charging module 53 to the first water tank to utilize waste heat. When the temperature in the charging module 53 is insufficient to heat the battery compartment 42, the electric heater 45 is used to heat the battery compartment 42.

[0098] The present invention also provides a charging and battery swapping station, including the aforementioned charging and battery swapping station thermal management system. Thus, the charging and battery swapping station can control different temperatures at different locations, while eliminating the need for traditional valves to control the temperature at different locations, maximizing the utilization of cooling capacity and reducing energy consumption at the charging and battery swapping station.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
