Description

Technical Field

[0001] This application belongs to the field of charging equipment technology, specifically relating to a battery swapping cabinet. Background Technology

[0002] Battery swapping stations are used to charge the batteries of electric vehicles and are an essential infrastructure for electric vehicle energy services. Currently, with the increasing prevalence of electric vehicles, higher demands are being placed on the durability of battery swapping stations.

[0003] Traditional battery swapping cabinets typically consist of a cabinet with a battery compartment. The battery compartment's interior cavity houses the batteries. During use, when charging the batteries, both the batteries themselves and the electronic components within the battery compartment that power them generate heat. Currently, this heat is dissipated solely through natural cooling, which is slow and allows heat to accumulate within the battery compartment. This can lead to high temperatures within the battery compartment, which can damage the electronic components and result in poor durability of the battery swapping cabinet. Summary of the Invention

[0004] The purpose of this application is to provide a battery swapping cabinet that can solve the problem of poor durability of battery swapping cabinets in related technologies.

[0005] This application provides a battery swapping cabinet, including:

[0006] The cabinet has a heat exchange chamber and a battery compartment, and the heat exchange chamber is connected to the outside.

[0007] The system includes a liquid storage container, a first heat exchanger, a second heat exchanger, and a pressurizing device. The liquid storage container is used to store heat exchange liquid. The first heat exchanger is located in the battery compartment, and the second heat exchanger is located in the inner cavity of the heat exchange compartment. The liquid outlet of the liquid storage container, the first heat exchanger, the second heat exchanger, and the liquid inlet of the liquid storage container are sequentially connected to form a liquid transport circuit for transporting the heat exchange liquid. The pressurizing device is located on the liquid transport circuit and is used to drive the heat exchange liquid to circulate in the liquid transport circuit. The heat exchange liquid flows from the first heat exchanger to the second heat exchanger.

[0008] An air extraction component is connected to the heat exchange chamber and is used to draw outside air into the heat exchange chamber.

[0009] In this embodiment, a first heat exchanger is located in the battery compartment, and a second heat exchanger is located inside the heat exchange compartment. The outlet of the liquid storage container, the first heat exchanger, the second heat exchanger, and the inlet of the liquid storage container are sequentially connected, forming a liquid transport circuit for transporting the heat exchange liquid. A pressurizing device is located on the liquid transport circuit and is used to drive the heat exchange liquid to circulate in the liquid transport circuit. The heat exchange liquid flows from the first heat exchanger to the second heat exchanger. An air extraction device is connected to the heat exchange compartment and is used to draw outside air into the heat exchange compartment. With this configuration, when the heat exchange liquid flows through the first heat exchanger, it exchanges heat with the battery compartment. At this time, the heat exchange liquid can absorb at least part of the heat from the battery compartment, thereby lowering the temperature of the battery compartment. Subsequently, when the heat exchange liquid flows through the second heat exchanger, it can exchange heat with the outside air, thereby dissipating at least part of the absorbed heat. As can be seen, in the embodiments of this application, the first heat exchanger and the second heat exchanger can dissipate at least part of the heat of the battery compartment. In this way, the battery compartment of the battery swapping cabinet provided in the embodiments of this application can dissipate heat not only through natural heat dissipation, but also by relying on the first heat exchanger and the second heat exchanger, thereby making the heat dissipation efficiency of the battery compartment high. As a result, the probability of the electronic components in the battery compartment cavity being damaged by temperature is low, thereby making the battery swapping cabinet more durable.

All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0026] The battery swapping cabinet provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0027] Please refer to Figures 1 to 5 As shown in the embodiment of this application, a battery swapping cabinet is provided, including: cabinet body 100, liquid storage container 210, first heat exchanger 220, second heat exchanger 230, pressurization device 240 and air extraction component 250.

[0028] Specifically, the cabinet 100 has a heat exchange chamber 110 and a battery compartment 120. The heat exchange chamber 110 is connected to the outside. More specifically, the cabinet 100 is provided with vents, and the heat exchange chamber 110 is connected to the outside through the vents.

[0029] The storage container 210 stores the heat exchange liquid. A first heat exchanger 220 is located in the battery compartment 120, and a second heat exchanger 230 is located inside the heat exchange chamber 110. The outlet of the storage container 210, the first heat exchanger 220, the second heat exchanger 230, and the inlet of the storage container 210 are sequentially connected, forming a liquid transport circuit 300 for transporting the heat exchange liquid. A pressurizing device 240 is located on the liquid transport circuit 300 and is used to drive the heat exchange liquid to circulate within the liquid transport circuit 300. The pressurizing device 240 is, for example, a water pump, and the heat exchange liquid flows from the first heat exchanger 220 to the second heat exchanger 230. Specifically, the heat exchange liquid flows sequentially, for example, through the outlet of the storage container 210, the first heat exchanger 220, the second heat exchanger 230, and the inlet of the storage container 210.

[0030] The air extraction component 250 is connected to the heat exchange chamber 110 and is used to draw outside air into the heat exchange chamber 110. The air extraction component 250 is, for example, a fan or an air pump.

[0031] In this embodiment, the first heat exchanger 220 is disposed in the battery compartment 120, and the second heat exchanger 230 is disposed in the inner cavity of the heat exchange chamber 110. The outlet of the liquid storage container 210, the first heat exchanger 220, the second heat exchanger 230 and the inlet of the liquid storage container 210 are sequentially connected to form a liquid transport circuit 300 for transporting heat exchange liquid. The pressurizing device 240 is disposed on the liquid transport circuit 300 and is used to drive the heat exchange liquid to circulate in the liquid transport circuit 300. The heat exchange liquid flows from the first heat exchanger 220 to the second heat exchanger 230. The air extraction device 250 is connected to the heat exchange chamber 110 and is used to draw outside air into the heat exchange chamber 110. With this configuration, when the heat exchange liquid flows through the first heat exchanger 220, it exchanges heat with the battery compartment 120. During this process, the heat exchange liquid absorbs at least a portion of the heat from the battery compartment 120, thereby lowering its temperature. Then, when the heat exchange liquid flows through the second heat exchanger 230, it exchanges heat with the outside air, dissipating at least a portion of the absorbed heat. Therefore, in this embodiment, the first heat exchanger 220 and the second heat exchanger 230 can conduct at least a portion of the heat from the battery compartment 120. Thus, in addition to natural heat dissipation, the battery compartment 120 of the battery swapping cabinet provided in this embodiment can also rely on the first heat exchanger 220 and the second heat exchanger 230 for heat dissipation, resulting in high heat dissipation efficiency. Consequently, the probability of damage to the electronic components inside the battery compartment 120 due to temperature fluctuations is low, thus improving the durability of the battery swapping cabinet.

[0032] Furthermore, when the temperature of the battery compartment 120 is lower than the temperature of the heat exchange liquid, after heat exchange occurs between the heat exchange liquid and the battery compartment 120, the battery compartment 120 can absorb at least part of the heat from the heat exchange liquid, thereby raising the temperature of the battery compartment 120. It should be noted that both high and low temperatures of the battery compartment 120 will affect battery charging. Therefore, when the temperature of the battery compartment 120 is high, it needs to be cooled down; conversely, when the temperature of the battery compartment 120 is low, it needs to be heated up.

[0033] Furthermore, when the temperature of the heat exchange liquid is lower than the temperature of the outside air, after the heat exchange liquid exchanges heat with the outside air, the heat exchange liquid can absorb at least part of the heat from the outside air, thereby raising the temperature of the heat exchange liquid.

[0034] In one specific implementation, the first heat exchanger 220 and the second heat exchanger 230 are both radiators, for example, and the heat exchange liquid is, for example, water.

[0035] In another embodiment, reference Figure 2 As shown, the power swapping cabinet also includes a liquid delivery branch 400, a first control valve 260, and a second control valve 270. The liquid delivery circuit 300 includes a first branch 310, and a second heat exchanger 230 is disposed in the first branch 310. In other words, the second heat exchanger 230 is connected in series with the first branch 310, and the heat exchange liquid flows through the first branch 310 and the second heat exchanger 230 at the same time.

[0036] The first branch 310 is connected in parallel with the liquid transport branch 400. Both ends of the first branch 310 and the liquid transport branch 400 are connected to the inlets of the first heat exchanger 220 and the liquid storage container 210, respectively. In other words, one end of the first branch 310 is connected to the first heat exchanger 220 and the other end is connected to the inlet of the liquid storage container 210. At the same time, one end of the liquid transport branch 400 is connected to the first heat exchanger 220 and the other end is connected to the inlet of the liquid storage container 210.

[0037] A first control valve 260 is located in the first branch 310 and is used to control the opening and closing of the first branch 310. A second control valve 270 is located in the liquid delivery branch 400 and is used to control the opening and closing of the liquid delivery branch 400. Specifically, both the first control valve 260 and the second control valve 270 are, for example, solenoid valves. When the first control valve 260 is in the open state, the first branch 310 is in the conducting state, and the heat exchange liquid can flow back to the liquid storage container 210 along the first branch 310. When the first control valve 260 is in the closed state, the first branch 310 is in the cut-off state, and the heat exchange liquid cannot flow through the first branch 310. Similarly, when the second control valve 270 is in the open state, the liquid delivery branch 400 is in the conducting state, and the heat exchange liquid can flow back to the liquid storage container 210 along the liquid delivery branch 400. When the second control valve 270 is in the closed state, the liquid delivery branch 400 is in the cut-off state, and the heat exchange liquid cannot flow through the liquid delivery branch 400.

[0038] In practical use, when the temperature of the battery compartment 120 is higher than the preset temperature, for example, the temperature of the heat exchange liquid is lower than the temperature of the battery compartment 120, and for example, the first control valve 260 is opened and the second control valve 270 is closed, so that the heat exchange liquid mainly flows back to the storage container 210 through the first branch 310. Since the heat exchange liquid will inevitably flow through the second heat exchanger 230 during the process of flowing through the first branch 310, the heat exchange liquid can exchange heat with the outside air, and thus the heat exchange liquid can dissipate at least part of the heat it has absorbed. When the temperature of the battery compartment 120 is lower than the preset temperature, for example, the temperature of the heat exchange liquid is made higher than the temperature of the battery compartment 120, and for example, the first control valve 260 is closed and the second control valve 270 is opened, so that the heat exchange liquid mainly flows back to the storage container 210 through the liquid delivery branch 400. In this case, the first branch 310 is in a cut-off state, and the heat exchange liquid cannot flow through the first branch 310, thus it cannot continuously exchange heat with the second heat exchanger 230. In this way, the heat exchange between the heat exchange liquid and the outside air can be reduced, thereby reducing the heat loss of the heat exchange liquid. It can be seen that, in this embodiment, by controlling the opening and closing of the first control valve 260 and the second control valve 270, the heat absorbed by the heat exchange liquid can be dissipated, and the heat exchange between the heat exchange liquid and the outside air can be reduced. Therefore, the solution adopted in this embodiment can better meet the heat exchange requirements of the battery compartment 120.

[0039] In other alternative embodiments, the battery swapping cabinet may also exclude the liquid delivery branch 400 and the second control valve 270 described above.

[0040] In another embodiment, reference Figure 1 and Figure 2As shown, the cabinet 100 also includes an electrical compartment 130, which is independent of the heat exchange compartment 110 and the battery compartment 120. Optionally, any two of the electrical compartment 130, heat exchange compartment 110, and battery compartment 120 may be independent. The battery swapping cabinet also includes an electronic component 500, a third heat exchanger 280, and a gas drive mechanism 290. The electronic component 500, the third heat exchanger 280, and the gas drive mechanism 290 are all located in the electrical compartment 130. The third heat exchanger 280 is located in the liquid delivery circuit 300 and between the outlet of the liquid storage container 210 and the second heat exchanger 230. The gas drive mechanism 290 is used to drive the gas in the inner cavity of the electrical compartment 130 to circulate in the inner cavity of the electrical compartment 130, so that the third heat exchanger 280 can exchange heat with the gas in the inner cavity of the electrical compartment 130 relatively quickly. The gas drive mechanism 290 is, for example, a fan. With this configuration, when the heat exchange liquid flows through the third heat exchanger 280, the heat exchange liquid can exchange heat with the gas in the inner cavity of the electrical compartment 130, thereby adjusting the temperature of the inner cavity of the electrical compartment 130 and preventing the temperature of the inner cavity of the electrical compartment 130 from being too high or too low. This can extend the service life of the electronic components 500 in the inner cavity of the electrical compartment 130.

[0041] As one specific implementation, the third heat exchanger 280 is, for example, a radiator.

[0042] In other alternative embodiments, the battery swapping cabinet may also exclude the third heat exchanger 280 and the gas drive mechanism 290.

[0043] In a further embodiment, the electrical compartment 130 is, for example, a closed structure. This provides better sealing of the electrical compartment 130, resulting in a higher level of protection and consequently a longer service life for the electronic components 500 within the electrical compartment 130's interior.

[0044] In other alternative embodiments, the electrical compartment 130 may also be an open structure.

[0045] In another embodiment, the battery swapping cabinet may further include a fire branch and a fire sprinkler head 600. The fire branch is independent of the liquid delivery circuit 300 and is used to deliver fire extinguishing liquid, such as water. The fire sprinkler head 600 is, for example, located in the inner cavity of the battery compartment 120 and is, for example, connected to the fire branch.

[0046] In other alternative embodiments, the fire sprinkler head 600 can also be directly connected to the first heat exchanger 220. Compared with the power swapping cabinet provided in the previous embodiment, the power swapping cabinet provided in this embodiment omits at least the fire branch circuit, thus the power swapping cabinet provided in this embodiment has a simpler structure and lower cost.

[0047] In actual use, when the electronic components in the inner cavity of the battery compartment 120 catch fire, the fire sprinkler head 600 can be automatically opened. At this time, the heat exchange liquid can be sprayed out from the fire sprinkler head 600, thereby extinguishing the fire on the electronic components.

[0048] In another embodiment, reference Figure 1 and Figure 5 As shown, the battery swapping cabinet also includes a charging component and a DC-DC converter module 520. The charging component is, for example, a charging cable. The electronic components 500 include a power distribution module and an AC-to-DC converter module 510. The power distribution module, the AC-to-DC converter module 510, the DC-DC converter module 520, and the charging component are electrically connected in sequence. The charging component and the DC-DC converter module 520 are, for example, both located inside the battery compartment 120. The battery compartment 120 is provided with heat dissipation holes. The DC-DC converter module 520 generates a lot of heat when it is working. By providing heat dissipation holes, the heat in the inner cavity of the battery compartment 120 can be dissipated, thereby preventing the temperature of the inner cavity of the battery compartment 120 from becoming too high.

[0049] In other alternative embodiments, the DC-DC converter module 520 may also be housed within the electrical compartment 130. In this case, the electronic components 500 mentioned above include, for example, the DC-DC converter module 520 in this embodiment, and the battery compartment 120, for example, does not have the aforementioned heat dissipation holes. In this embodiment, the battery compartment 120 does not have heat dissipation holes, thereby improving the sealing performance of the battery compartment 120 and thus increasing its protection level. Furthermore, this arrangement allows electronic components that generate significant heat, such as the power distribution module, the AC-to-DC converter module 510, and the DC-DC converter module 520, to be housed within the electrical compartment 130. This facilitates heat management of the heat exchange cabinet, enabling convenient and rapid heating or cooling of the battery exchange cabinet.

[0050] In practical use, the power distribution module receives AC power input from an external power source and transmits the AC power to the AC-to-DC module 510. Then, the AC-to-DC module 510 converts the AC power into DC power and transmits the converted DC power to the DC-DC conversion module 520. After that, the DC-DC conversion module 520 adjusts the voltage of the DC power to the preset voltage required for battery charging and charges the battery through the charging component.

[0051] As a specific implementation method, the power distribution module, the AC-to-DC module 510, and the DC-DC conversion module 520 are integrated into the same box. With this arrangement, the overall layout of the power distribution module, the AC-to-DC module 510, and the DC-DC conversion module 520 is more reasonable, thereby making the overall compactness of the power distribution module, the AC-to-DC module 510, and the DC-DC conversion module 520 better.

[0052] In another embodiment, the electrical compartment 130 is located at the top of the cabinet 100. With the bottom of the cabinet 100 supported on the ground, by positioning the electrical compartment 130 at the top of the cabinet 100, the electrical compartment 130 is kept away from the ground, thereby reducing the possibility of water entering the electrical compartment 130.

[0053] Further reference Figure 1 As shown, the heat exchange chamber 110 is located, for example, at the top of the cabinet 100, and the battery compartment 120 is located, for example, between the heat exchange chamber 110 and the electrical compartment 130. It should be noted that in this embodiment, "top" and "top" both refer to the battery swapping cabinet according to... Figure 1 The arrangement shown refers to what is meant when it is laid out as shown.

[0054] In other alternative embodiments, the electrical compartment 130 may also be located in the middle of the cabinet 100 or at the bottom of the cabinet 100.

[0055] In another embodiment, the second heat exchanger 230 and the third heat exchanger 280 are arranged in series. The series arrangement places lower flow requirements on the overall liquid delivery circuit 300, thereby reducing the requirements on the pressurization device 240 and consequently lowering the cost of the pressurization device 240.

[0056] As one specific implementation method, refer to Figure 2 As shown, the liquid transport circuit 300 includes, for example, a third branch 330, and a third heat exchanger 280 is provided on the third branch 330. The third branch 330 is connected in series with the first branch 310 and the liquid transport branch 400 mentioned above, thereby enabling the second heat exchanger 230 and the third heat exchanger 280 to be connected in series.

[0057] In practical use, the heat exchange liquid flows sequentially through the third branch 330 and the first branch 310, or sequentially through the third branch 330 and the liquid transport branch 400. Specifically, when the heat exchange liquid flows sequentially through the third branch 330 and the first branch 310, the heat exchange liquid, for example, first exchanges heat with the electrical chamber 130. At this time, the heat exchange liquid absorbs at least a portion of the heat from the electrical chamber 130. Then, when the heat exchange liquid flows through the first branch 310, it can exchange heat with the outside air, for example, through the second heat exchanger 230, thereby dissipating at least a portion of the heat absorbed by the heat exchange liquid.

[0058] In other alternative embodiments, the second heat exchanger 230 and the third heat exchanger 280 may also be connected in parallel.

[0059] In another embodiment, reference Figures 1 to 3As shown, there are at least two battery compartments 120 and at least two first heat exchangers 220. Each battery compartment 120 is equipped with at least one first heat exchanger 220. At least two battery compartments 120 are divided into multiple battery compartment groups. That is, all battery compartments 120 are divided into multiple battery compartment groups. A battery compartment group may include one battery compartment 120 or at least two battery compartments 120, and the number of battery compartments 120 included in each battery compartment group may be the same or different. Each first heat exchanger 220 corresponding to each battery compartment group is set on the same second branch 320 and is arranged sequentially along the extension direction of the second branch 320. The second branches 320 are arranged in parallel, and both ends of the extension direction of each second branch 320 are respectively connected to the liquid storage container 210 and the second heat exchanger 230. Specifically, for example, both ends of the extension direction of each second branch 320 are respectively connected to the liquid outlet of the liquid storage container 210 and the third branch 330 mentioned above. In actual use, the heat exchange liquid flows through the second branch 320 and sequentially through each of the first heat exchangers 220 installed on the second branch 320.

[0060] In this embodiment, at least two first heat exchangers 220 are connected in parallel. With this configuration, there is less mutual interference between the first heat exchangers 220. If one of the first heat exchangers 220 is damaged, some of the first heat exchangers 220 can still work normally.

[0061] In other alternative embodiments, each of the first heat exchangers 220 may be connected in series. In this case, each of the first heat exchangers 220 may be connected in series on the same fourth branch, and the two ends of the fourth branch itself in the extension direction may be connected to the liquid storage container 210 and the second heat exchanger 230 respectively.

[0062] In another embodiment, there are at least two battery compartments 120, each of which is provided with at least one first heat exchanger 220. The at least two battery compartments 120 are arranged sequentially along a first direction, and adjacent battery compartments 120 in the first direction share a common wall. The first heat exchanger 220 is located in the common wall shared by the two adjacent battery compartments 120. This arrangement allows the same first heat exchanger 220 to exchange heat with two adjacent battery compartments 120 simultaneously, thus reducing the number of first heat exchangers 220 and resulting in a simpler overall structure and lower cost for the battery swapping cabinet.

[0063] Specifically, the first direction is, for example, the height of the cabinet (100mm). More specifically, for example... Figure 1 The direction indicated by the middle arrow A.

[0064] Further reference Figure 1As shown, at least two battery compartments 120 include, for example, a first battery compartment 120a and a second battery compartment 120b. The first battery compartment 120a and the second battery compartment 120b are arranged sequentially along a first direction. The first battery compartment 120a includes a first compartment wall 121 and a second compartment wall 122. The second battery compartment 120b includes a third compartment wall 123 and the aforementioned first compartment wall 121. The third compartment wall 123, the first compartment wall 121, and the second compartment wall 122 are arranged sequentially along the first direction. The first battery compartment 120a and the second battery compartment 120b share the first compartment wall 121. Each of the first compartment wall 121, the second compartment wall 122, and the third compartment wall 123 is provided with a first heat exchanger 220. With this arrangement, each of the first battery compartment 120a and the second battery compartment 120b corresponds to at least two first heat exchangers 220, thereby making the heat exchange efficiency of both the first battery compartment 120a and the second battery compartment 120b relatively high.

[0065] In other alternative embodiments, each first heat exchanger 220 may also be disposed in the inner cavity of its corresponding battery compartment 120.

[0066] In another embodiment, the battery swapping cabinet also includes a heater 700, which is disposed in the liquid storage container 210 and can heat the heat exchange liquid. This configuration allows the temperature of the heat exchange liquid to be adjusted according to the heat exchange requirements of the battery compartment 120, thereby reducing energy waste.

[0067] In practical use, the heater 700 is turned on, which heats the heat exchange liquid, thereby raising its temperature. If the temperature of the battery compartment 120 is lower than the preset temperature, the temperature of the heat exchange liquid is adjusted to ensure it is not lower than the preset temperature. When the heat exchange liquid exchanges heat with the battery compartment 120, the battery compartment 120 absorbs at least part of the heat from the heat exchange liquid, thereby raising its temperature.

[0068] In other alternative embodiments, the battery swapping cabinet may also exclude the heater 700.

[0069] In another embodiment, reference Figure 1 and Figure 2 As shown, the battery swapping cabinet also includes a flow detection device 800, which is located in the liquid delivery circuit 300 and is used to detect the flow rate of the liquid delivery circuit 300.

[0070] In practical use, if the liquid delivery circuit 300 becomes blocked, the actual flow rate of the liquid delivery circuit 300 will be less than the preset flow rate. Therefore, the flow detection device 800 can detect the flow rate of the liquid delivery circuit 300, allowing the user to quickly and easily determine whether the liquid delivery circuit 300 is blocked. Furthermore, with the help of the flow detection device 800, the user can intuitively understand the flow rate of the liquid delivery circuit 300, enabling the user to easily and quickly adjust the flow rate of the liquid delivery circuit 300.

[0071] As one specific implementation, the flow detection device 800 is, for example, a flow sensor.

The specific embodiments described above are merely illustrative and not restrictive.
