[0047] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0048] The battery pack thermal management cabin according to the present application is described below with reference to the accompanying drawings.

[0049] like Figure 1 As shown, the present application provides a battery pack thermal management cabin 4, wherein the battery pack thermal management cabin 4 includes;

[0050] A compartment 13 for a vehicle 1 to enter, the vehicle 1 including a battery pack 7;

[0051] A coolant pipe 25 is used to transport the coolant, one end of the coolant pipe 25 is arranged outside the compartment 13, and the other end is arranged inside the compartment 13;

[0052] The driving member 23 is connected to the coolant pipe 25 and is used to extract coolant from the outside of the compartment 13 through the coolant pipe 25 and inject it into the interior of the compartment 13 to cool the battery pack 7.

[0053] In the embodiments of the present application, Figure 1As shown, a battery pack thermal management cabin 4 of the present application is mainly composed of a compartment 13, a coolant pipe 25 and a drive member 23. Among them, the compartment 13 is the basic structure of the entire cabin, which can be a rectangular parallelepiped, and its door 3 is arranged on the compartment 13, which can be opened to the ground and form a plane, including an inclined plane or a horizontal plane. The connection mode of the door and the compartment can be a rotation connection with the compartment, so that it can be flipped open to the ground, or it can be a detachable door. This design facilitates the vehicle 1, especially the new energy vehicle loaded with the battery pack 7, to smoothly enter the compartment 13. The coolant pipe 25 runs through the compartment 13, one end is outside the compartment 13, and a coolant inlet 14 is formed on the compartment 13, which can be connected to an external coolant tank, and the other end is inside the compartment 13 to form a coolant outlet 18. The coolant pipe 25 can be arranged on the side away from the door 3, responsible for extracting coolant from the coolant tank and transporting it to the inside of the compartment 13, providing a medium channel for cooling the battery pack 7. The driving member 23 may be an electric water pump, a diaphragm pump or a gear pump, etc. It may be arranged inside the compartment 13 and connected to the coolant pipe 25, or it may be arranged outside the compartment 13 alone. Its function is to provide power, extract coolant from the outside of the compartment 13 through the coolant pipe 25, and inject it into the compartment 13, thereby cooling the battery pack 7 and solving the heat dissipation problem of the battery pack 7 during operation.

[0054] In one embodiment, the battery pack thermal management cabin 4 also includes a first ball valve 15 and a second ball valve 17 arranged on the coolant pipeline 25, the first ball valve 15 is used to control the opening and closing of the inlet of the coolant pipeline, and the second ball valve 17 is used to control the opening and closing of the outlet of the coolant pipeline.

[0055] In this embodiment, the coolant pipe 25 located inside the compartment 13 includes two coolant outlets 18, and there are also two corresponding second ball valves 17, which are respectively arranged at the two coolant outlets 18 to control the opening and closing of the two coolant outlets 18, so as to accurately control the opening and closing of the channel for the coolant to enter the compartment 13. When the battery pack 7 needs to be cooled, the first ball valve 15 is opened to allow the coolant to flow in; when not needed, it is closed to prevent the coolant from leaking or unnecessary flow. The second ball valve 17 is arranged at the coolant inlet 14 to control the passage for extracting the coolant from the outside. It can be opened or closed at the appropriate time according to actual needs to ensure that the coolant extraction process is controllable and improve the stability and reliability of the entire cooling system.

[0056] By adjusting the opening of the first ball valve 15 and the second ball valve 17, the flow rate of the coolant can be flexibly controlled. When the battery pack 7 is seriously heated, the ball valve opening can be appropriately increased to increase the flow rate of the coolant and improve the cooling efficiency; when the battery pack 7 is slightly heated, the ball valve opening can be reduced to reduce the flow rate of the coolant, making the cooling process more accurate and efficient.

[0057] In one embodiment, the battery pack thermal management cabin 4 further includes a third ball valve 20 and a coolant discharge port 19 disposed in the compartment 13 , and the third ball valve 20 is used to control the opening and closing of the coolant discharge port 19 so that the coolant is discharged from the coolant discharge port 19 .

[0058] In this embodiment, the battery pack thermal management cabin 4 further includes a third ball valve 20 and a coolant discharge port 19 disposed in the compartment 13. The third ball valve 20 is used to control the opening and closing of the coolant discharge port 19. When the battery pack 7 is cooled or the coolant needs to be replaced, the controller 12 controls the third ball valve 20 to open, and the coolant in the compartment 13 can be discharged from the coolant discharge port 19. The discharged coolant can be subsequently processed or recycled, so that the entire cooling process forms a complete cycle.

[0059] The third ball valve 20 controls the opening and closing of the coolant discharge port 19, so that the old coolant in the compartment 13 can be discharged in time when needed, so as to prepare for the injection of new coolant. This helps to maintain the good performance of the coolant, ensure that the battery pack 7 can always be effectively cooled, and extend the service life of the battery pack 7.

[0060] In one embodiment, the battery pack thermal management cabin 4 further includes a controller 12 and a temperature detection device 6 disposed in the cabin 13;

[0061] The temperature detection device 6 is used to detect the temperature inside the battery pack 7;

[0062] The controller 12 is configured to:

[0063] When the temperature reaches the first preset temperature, the driving member 23 is controlled to work, and the first ball valve 15 and the second ball valve 17 are opened to cool the battery pack 7; and

[0064] When the temperature reaches a second preset temperature, the third ball valve 20 is opened to discharge the coolant from the coolant discharge port 19 . The second preset temperature is lower than the first preset temperature.

[0065] In this embodiment, the temperature detection device 6 is installed in the middle area of ​​the compartment 13, corresponding to the position of the battery pack 7 of the vehicle 1, and can be a temperature sensor that can detect the temperature data in the battery pack 7 in real time. Figure 2 As shown, Figure 2 It is a schematic diagram of the thermal management process of battery pack 7.

[0066] The controller 12, as the control core of the entire cabin, is configured to control the driver 23 to start working when the temperature detected by the temperature detection device 6 reaches the first preset temperature. The first preset temperature is set according to the safe operating temperature range of the battery pack 7. When the temperature of the battery pack 7 reaches this value, it means that the battery pack 7 begins to overheat and needs to be cooled. At this time, the controller 12 promptly controls the driver 23 to extract the coolant and open the first ball valve 15 and the second ball valve 17 to cool the battery pack 7 to ensure the normal operation of the battery pack 7.

[0067] When the temperature detected by the temperature detection device 6 reaches the second preset temperature, the controller 12 opens the third ball valve 20. The second preset temperature is lower than the first preset temperature, which means that when the battery pack 7 is cooled, the temperature drops to a certain level, lower than the first preset temperature and reaches the second preset temperature, indicating that the battery pack 7 has been effectively cooled. At this time, the third ball valve 20 is opened to discharge the coolant from the coolant discharge port 19 to prevent the coolant from overcooling the battery pack 7, and at the same time, it is convenient to replace or recycle the coolant.

[0068] In addition, in the present embodiment, the battery pack thermal management cabin 4 also includes a battery pack identification device, which is arranged inside the compartment 13 and can be used to identify the type of the battery pack 7. Correspondingly, the controller 12 can be configured to determine the optimal cooling temperature of the battery pack 7 according to the type of the battery pack 7; when the temperature of the battery pack 7 reaches the optimal cooling temperature, the third ball valve 20 is opened to allow the coolant to be discharged from the coolant outlet. Among them, the battery pack identification device can be a voltage sensor, a current sensor, a temperature sensor, etc. Because different types of battery packs 7 have differences in voltage, current change characteristics, and operating temperature ranges. For example, the voltage platforms of lithium-ion batteries and lead-acid batteries are different. Therefore, by continuously monitoring the voltage of the battery pack 7 through a voltage sensor, combined with other parameters, the type of the battery pack 7 can be preliminarily determined.

[0069] The temperature detection device 6 and the controller 12 work together to make the entire cooling process unnecessary for manual real-time monitoring and operation. With this intelligent thermal management cabin, multiple battery packs 7 can be efficiently and accurately controlled in temperature at the same time, thereby improving work efficiency and management level.

[0070] In one embodiment, the battery pack thermal management cabin 4 includes a distance detection device 5 and a hydraulic power unit 22. The distance detection device 5 is arranged outside the compartment 13 to detect the distance between the vehicle 1 and the compartment 13; the hydraulic power unit 22 is arranged inside the compartment 13 to control the opening and closing of the compartment door 3;

[0071] The controller 12 is configured to:

[0072] When the distance reaches a preset distance, the hydraulic power unit 22 is controlled to open the compartment door 3;

[0073] When a pressure signal is received and the pressure signal remains unchanged within a preset time range, the hydraulic power unit 22 is controlled to close the compartment door 3 .

[0074] In this embodiment, the distance detection device 5 can be a camera, which is arranged outside the compartment 13 and close to the side of the compartment door 3. It can detect the distance information between the vehicle 1 and the compartment 13 in real time. The hydraulic power unit 22 is arranged inside the compartment 13, and is mainly used to control the opening and closing actions of the compartment door 3.

[0075] like Figure 3 As shown, Figure 3 It is a schematic diagram of the operation principle of vehicle 1 entering the cabin and stopping. According to the data detected by the distance detection device 5, when the distance reaches the preset distance, the controller 12 determines that the vehicle 1 is close to the cabin, and then controls the hydraulic power unit 22 to open the cabin door 3 to facilitate the entry of the vehicle 1; the pressure detection device 9 and the lifting stop block 10 are both arranged at the bottom of the cabin 13. When the vehicle 1 enters the cabin 13, the weight of the vehicle 1 will generate pressure on the bottom of the cabin 13. The pressure detection device 9 can detect this pressure and convert it into a pressure signal. When the controller 12 receives the pressure signal and keeps it unchanged for a preset time, it determines that the vehicle 1 has completely entered the cabin 13, and then controls the hydraulic power unit 22 to close the cabin door 3, and controls the lifting stop block 10 to rise to stop the vehicle 1. This design completes the automatic control process and the stopping process of the cabin door 3, improves the convenience and safety of the cabin, prevents the cabin door 3 from being accidentally closed when the vehicle 1 is not completely entered, and ensures the safety of the vehicle 1 and personnel.

[0076] The intelligent control of the opening and closing of the door 3 is realized through the coordinated work of the distance detection device 5, the pressure detection device 9 and the controller 12. This intelligent control logic can automatically adjust the state of the door 3 according to the actual state of the vehicle 1 and the shelter, making the operation of the shelter more intelligent and automatic.

[0077] In one embodiment, the battery pack thermal management cabin 4 includes a liquid level detection device 21, which is disposed inside the compartment 13 and is used to detect the liquid level of the coolant in the compartment 13 to obtain a liquid level signal;

[0078] The controller 12 is configured to:

[0079] When the received liquid level signal indicates that the liquid level has reached a preset height, the coolant pipeline 25 and the driving member 23 are closed.

[0080] In this embodiment, the liquid level detection device 21 may be a liquid level sensor, which may be installed at the bottom of the vehicle to detect the liquid level of the coolant. Alternatively, it may be installed at a height flush with the battery pack 7 of the vehicle 1 to facilitate detection of the liquid level. It may also be installed at different heights according to different vehicle models, thereby satisfying thermal management tests of different vehicle models 1.

[0081] The liquid level detection device 21 converts the liquid level information into a hydraulic signal and transmits it to the controller 12. When the liquid level detection device 21 is installed at the bottom of the vehicle, when the controller 12 receives the liquid level reaching a preset height or other abnormal hydraulic signals, it determines that the coolant is sufficient or an abnormal situation occurs. At this time, the coolant pipe 25 and the drive member 23 are closed to avoid coolant overflow or other failures, ensure the normal operation of the cooling system, and prevent the equipment from being damaged due to too much or too little coolant. When the liquid level detection device 21 is installed at a height flush with the battery pack 7, when the controller 12 detects the liquid level signal, it means that the liquid level has reached a height flush with the battery pack, and the cooling pipe 25 and the drive member 23 are closed.

[0082] The coolant pipeline 25 is closed, specifically, the first ball valve 15 and the second ball valve 17 may be closed, thereby closing the coolant pipeline 25 .

[0083] The liquid level of the coolant in the compartment 13 is monitored in real time by the liquid level detection device 21. When the coolant level reaches the upper limit, a hydraulic signal is generated and transmitted to the controller 12. After receiving the signal, the controller 12 immediately closes the coolant pipe 25 and the drive member 23 to prevent the coolant from continuing to flow into the compartment 13. It can effectively prevent the coolant from overflowing, avoid the coolant from damaging the electrical equipment, mechanical parts, etc. in the battery pack thermal management cabin 4, reduce equipment failures and safety accidents caused by coolant leakage, and ensure the normal operation and service life of the equipment.

[0085] In this embodiment, the energy supply device 16 can be a generator set, which is arranged inside the cabin 13, or it can be in the form of an external power interface. It provides energy support for the entire cabin. The drive 23, various ball valves, controller 12, detection device and other equipment in the cabin need to consume electrical energy during operation. The energy supply device 16 can ensure that each device in the cabin can operate stably and realize the thermal management function of the battery pack 7.

[0086] In one embodiment, the battery pack thermal management cabin 4 further includes an external lighting device 24 and an internal lighting device 8 . The external lighting device 24 is disposed outside the compartment 13 , and the internal lighting device 8 is disposed inside the compartment 13 .

[0087] In this embodiment, the external lighting device 24 can be arranged on the top of the exterior of the compartment 13, and can be a lifting lighting device. Through the lifting operation, it can provide lighting for the exterior of the cabin. When the lighting device is raised, the lighting range is larger and the light is darker; when the lighting device is lowered, the lighting range is smaller and the light is brighter. The internal lighting device 8 can provide lighting for the interior of the cabin, which is convenient for the driver to operate the vehicle 1 and display the internal situation of the compartment 13.

[0088] The internal lighting device 8 and the external lighting device 24 can provide lighting for the inside and outside of the cabin, which is convenient for the experimenters to operate, and at the same time better displays the test conditions inside the cabin 13, thereby improving the operation efficiency.

[0089] In another embodiment of the present application, the battery pack thermal management cabin 4 of the present application further includes a monitoring camera 2 and an intelligent air conditioner 11 arranged in the compartment 13, and the monitoring camera 2 can be used to record the real-time situation in the compartment 13. The intelligent air conditioner 11 is used to maintain the temperature in the compartment 13. The intelligentization of the cabin can be further realized by the monitoring camera 2 and the intelligent air conditioner 11.

[0090] In another embodiment of the present application, in order to facilitate movement, a moving device, such as wheels, slide rails, etc., can be installed on the body 13 to facilitate the movement of the body 13 and improve adaptability.

[0091] In another embodiment of the present application, the battery pack thermal management cabin 4 also includes a self-cleaning and regeneration module. The module is connected to the coolant discharge port 19. It may include a filtering device, a purification device, and an additive injection device. The filtering device can remove impurities and particles in the coolant, the purification device uses physical or chemical methods to remove pollutants and harmful substances in the coolant, and the additive injection device adds preservatives, antifreeze and other additives in a timely manner according to the performance test results of the coolant to restore and maintain the performance of the coolant. The service life of the coolant is extended, the frequency of coolant replacement is reduced, and the operating cost is reduced.

[0092] In another embodiment of the present application, the battery pack thermal management cabin 4 may also include a wireless energy transmission device. When the vehicle 1 enters the cabin, it can not only perform thermal management on the battery pack 7, but also charge the battery pack 7 through wireless energy transmission technology. At the same time, the controller 12 can intelligently adjust the charging power and cooling strategy according to the temperature and power status of the battery pack 7, so as to achieve coordinated optimization of thermal management and charging process.
