Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0050] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.

[0051] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0052] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0053] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0054] The present application provides a charging and discharging device 100, see Figure 1 , Figure 2 and Figure 3 The charging and discharging device 100 includes: a charging and discharging unit 1 and a shell 2, wherein the charging and discharging unit 1 includes a frame 11, a carrier 12 and a conductive docking connector 13, the shell 2 is arranged on the frame 11 to enclose a mounting cavity 21, the carrier 12 and the conductive docking connector 13 are both arranged on the frame 11 and are both located in the mounting cavity 21, the carrier 12 is used to carry a component to be tested, and at least one of the conductive docking connector 13 and the carrier 12 is used to move in a direction close to or away from the other, so that the conductive docking connector 13 is pressed against the component to be tested to perform a charging and discharging test on the component to be tested or leaves the component to be tested.

[0055] In this embodiment, when performing a charge and discharge test, first, the component to be tested can be placed on the carrier 12, and then, at least one of the conductive docking connector 13 and the carrier 12 can be moved in a direction close to the other, so that the component to be tested is clamped between the conductive docking connector 13 and the carrier 12, and finally, the charge and discharge test can be performed on the component to be tested through the conductive docking connector 13. At this point, the purpose of performing a charge and discharge test on the component to be tested is achieved.

[0056] Among them, since the supporting platform 12 and the conductive docking connector 13 of the charge and discharge unit 1 are both located in the installation cavity 21 formed by the outer shell 2, that is, the charge and discharge unit 1 is located in the installation cavity 21 formed by the outer shell 2. When the charge and discharge unit 1 is located in the installation cavity 21 formed by the outer shell 2, the charge and discharge unit 1 can be placed in a relatively closed environment, and the relatively closed environment can meet conditions such as explosion-proof sealing. In this way, when the component to be tested is clamped between the conductive docking connector 13 and the supporting platform 12 for charge and discharge test of the component to be tested, the environment in which the component to be tested is located can meet the requirements, thereby making the test effect of the charge and discharge device 100 better.

[0057] In addition, since the supporting platform 12 and the conductive docking connector 13 are both arranged on the frame 11, the shell 2 is arranged on the frame 11, in layman's terms, the shell 2 is arranged on the frame 11 of the charging and discharging unit 1, and the shell 2 and the charging and discharging unit 1 share the same frame 11. In the related art, an additional cabinet is usually arranged outside the charging and discharging unit 1. When an additional cabinet is arranged outside the charging and discharging unit 1, the charging and discharging unit 1 and the cabinet in the related art will each have their own frame. Therefore, the charging and discharging device 100 can save the number of frames 11, so that the structure of the charging and discharging device 100 is simple, the volume is reduced, the floor space is reduced, and the cost is reduced.

[0058] In addition, since the outer shell 2 is arranged on the frame 11 to enclose the installation cavity 21, the support platform 12 and the conductive docking terminal 13 are both arranged on the frame 11 and are both located in the installation cavity 21, therefore, the outer shell 2 and the charging and discharging unit 1 can jointly form a cabinet-like structure. On the one hand, the cabinet structure is convenient for subsequent stacking into combination cabinets as needed to adapt to different application requirements, so that the charging and discharging device 100 has a wider range of adaptability scenarios. On the other hand, when the combination cabinet needs to be transported, the combination cabinet can also be disassembled into charging and discharging devices 100 one by one for transportation, which is very flexible.

[0059] The component to be tested may be a battery. Of course, based on different application scenarios, the component to be tested may also be other possible components, which is not limited in this embodiment.

[0060] When the component to be tested is a battery, the conductive connector 13 may be a probe. Of course, in other application scenarios, the conductive connector 13 may also be other possible structures. This embodiment does not limit the conductive connector 13.

[0061] The carrying platform 12 may be a frame structure or any possible structure as long as it can carry the components to be tested. The present embodiment does not limit the specific structure of the carrying platform 12 .

[0062] In some embodiments, see Figure 1 and Figure 2 A partition 22 is provided in the installation cavity 21 , and the partition 22 divides the installation cavity 21 into a main cavity 211 and a sub-cavity 212 . The supporting platform 12 and the conductive docking terminal 13 are both located in the main cavity 211 .

[0063] By providing a partition 22 in the installation cavity 21, and making the partition 22 separate the installation cavity 21 into a main cavity 211 and a sub-cavity 212, the main cavity 211 and the sub-cavity 212 can form relatively independent spaces. With such a configuration, when the carrier 12 and the conductive butt joint 13 are subjected to charge and discharge tests in the main cavity 211, they can be free from the influence of the sub-cavity 212, making the environment of the charge and discharge tests more stable. At the same time, the sub-cavity 212 can also be free from the influence of the main cavity 211, making the environment of the sub-cavity 212 more stable.

[0064] In addition, the installation cavity 21 is divided into a main cavity 211 and a sub-cavity 212 by a partition 22. In addition to the main cavity 211 being able to place the support platform 12 and the conductive docking connector 13 for charging and discharging testing, the extra sub-cavity 212 can be reserved for other purposes, making the charging and discharging device 100 more expandable and providing a better user experience.

[0065] Further, in some embodiments, see Figure 1 and Figure 2 The sub-cavity 212 includes a first sub-cavity 2121 and a second sub-cavity 2122. The first sub-cavity 2121 and the second sub-cavity 2122 are arranged along the horizontal direction ( Figure 1 The partition 22 located between the first sub-cavity 2121 and the main cavity 211 is the first partition 221, and the partition 22 located between the second sub-cavity 2122 and the main cavity 211 is the second partition 222.

[0066] Since the first sub-cavity 2121 and the second sub-cavity 2122 are located on both sides of the main cavity 211 in the horizontal direction, on the one hand, the structural layout of the charging and discharging device 100 can be relatively regular, beautiful, and easy to manufacture. On the other hand, the sub-cavity 212 can be arranged roughly around the main cavity 211, which is convenient for the linkage between each sub-cavity 212 and the main cavity 211. On the other hand, the sub-cavity 212 can protect the main cavity 211 around the main cavity 211, so that the main cavity 211 is as far as possible from or free from external interference, thereby making the environment of the charging and discharging test more stable.

[0067] Of course, in other embodiments, the sub-cavity 212 may include a third sub-cavity and a fourth sub-cavity in addition to the first sub-cavity 2121 and the second sub-cavity 2122 . The present embodiment does not limit the number of sub-cavities 212 .

[0068] In order to make the temperature of the main chamber 211 meet the requirements, and then make the ambient temperature of the charge and discharge test meet the requirements, so as to achieve better results of the charge and discharge test, in some embodiments, see Figure 1 and Figure 4 A heat exchange component 3 is disposed on the partition 22 , and the heat exchange component 3 is used for performing heat exchange between the main cavity 211 and the auxiliary cavity 212 .

[0069] Since the heat exchange component 3 can perform heat exchange between the main chamber 211 and the auxiliary chamber 212, the temperature of the main chamber 211 can be adjusted in time so that the temperature of the main chamber 211 meets the requirements, and the ambient temperature of the charge and discharge test meets the requirements, thereby achieving better results of the charge and discharge test.

[0070] There are many ways to implement the heat exchange component 3. In one possible implementation, see Figure 4 , Figure 5 and Figure 6 The heat exchange component 3 includes: a heat exchanger 31 and a first heat dissipation fan 32, wherein the heat exchanger 31 is arranged on the partition 22, and is used to perform heat exchange between the main cavity 211 and the auxiliary cavity 212, and the first heat dissipation fan 32 is arranged on the partition 22, and is used to accelerate the flow speed of the gas between the main cavity 211 and the auxiliary cavity 212.

[0071] Driven by the first heat dissipation fan 32, the gas in the main chamber 211 can flow into the sub-chamber 212 through the heat exchanger 31. In the process of the gas flowing into the sub-chamber 212 through the heat exchanger 31, the heat exchanger 31 can heat or cool the gas. After the gas is heated or cooled, the first heat dissipation fan 32 can drive the heated or cooled gas back into the main chamber 211 to adjust the temperature of the main chamber 211, so as to achieve the purpose of making the temperature of the main chamber 211 meet the requirements, and further achieve the purpose of making the ambient temperature of the charge and discharge test meet the requirements.

[0072] Since the technology of heat exchange through the heat exchanger 31 and the first heat dissipation fan 32 is mature, the reliability of the operation of the heat exchange component 3 can be guaranteed.

[0073] Further, in order to more accurately adjust the temperature of the main chamber 211, in some embodiments, see Figure 4 The heat exchange component 3 also includes a temperature detection module 33, which is used to detect the temperature in the main cavity 211. In this way, when the temperature detection module 33 detects that the temperature in the main cavity 211 does not meet the requirements, the power of the first cooling fan 32 can be adjusted in time, thereby achieving the purpose of accurately adjusting the temperature of the main cavity 211.

[0074] The temperature detection module 33 may be a temperature detection sensor, etc., and it only needs to be able to detect the temperature in the main cavity 211 . The present embodiment does not limit the temperature detection module 33 .

[0075] In general, the main function of the heat exchanger 31 is to cool the gas passing through it, that is, the main function of the heat exchanger 31 is to refrigerate the gas passing through it. It can be understood that the gas with a lower temperature has a higher density, and the gas with a higher temperature has a lower density. Therefore, in order to facilitate the timely delivery of the gas cooled by the heat exchanger 31 to the main chamber 211 for cooling the main chamber 211, in some embodiments, see Figure 4 The first cooling fan 32 is located below the heat exchanger 31 in the vertical direction.

[0076] By locating the first cooling fan 32 below the heat exchanger 31 in the vertical direction, the gas cooled by the heat exchanger 31 can automatically reach the first cooling fan 32 under the action of gravity. After the cooled gas reaches the first cooling fan 32, the first cooling fan 32 can drive the cooled gas into the main cavity 211, thereby achieving the purpose of quickly cooling the main cavity 211.

[0077] In order to make the refrigerated gas circulate quickly in the main chamber 211 and fill every corner of the main chamber 211 to cool the main chamber 211, in some embodiments, see Figure 2 A second heat dissipation fan 2111 is disposed in the main cavity 211 , and the second heat dissipation fan 2111 is disposed closer to the bottom of the main cavity 211 than to the top of the main cavity 211 in the vertical direction.

[0078] By setting a second cooling fan 2111 in the main cavity 211, and making the second cooling fan 2111 closer to the bottom of the main cavity 211 than the top of the main cavity 211 in the vertical direction, under the driving action of the second cooling fan 2111, the refrigerated gas driven into the main cavity 211 by the first cooling fan 32 can quickly fill the main cavity 211 from bottom to top, and the refrigerated gas will become hot gas after reaching the main cavity 211, and the hot gas can re-enter the sub-cavity 212 through the heat exchanger 31.

[0079] It can be seen that by arranging a second cooling fan 2111 in the main cavity 211 and arranging the second cooling fan 2111 closer to the bottom of the main cavity 211 than to the top of the main cavity 211 in the vertical direction, the heat exchange efficiency between the main cavity 211 and the auxiliary cavity 212 can be further accelerated.

[0080] Specifically, the gas flow direction can be as follows Figure 6 Indicated by the arrow.

[0081] When the charging and discharging device 100 performs a charging and discharging test on the test element in the installation cavity 21, an abnormality may occur. When an abnormality occurs, such as a fire, the charging and discharging device 100 will have a fire protection requirement. Based on this, in some embodiments, see Figure 1 and Figure 7 The shell 2 is provided with a fire opening 23 connected with the installation cavity 21 , and a fire door assembly 4 which can open or close the fire opening 23 is provided at the fire opening 23 .

[0082] By providing the fire door assembly 4, when a fire occurs in the installation cavity 21, the fire opening 23 can be closed in time through the fire door assembly 4, so that the fire can be prevented from spreading through the fire opening 23 to the outside of the charging and discharging device 100 and threatening the personal safety of personnel.

[0083] The shape of the fire-fighting opening 23 may be circular, rectangular or other possible shapes, which is not limited in this embodiment.

[0084] It should be noted that there are many ways to implement the fire door assembly 4. In one possible implementation, see Figure 7 and Figure 8The fire door assembly 4 includes: a door frame 41, a fire door 42, a fire door driver 43 and an in-place detection element 44, wherein the door frame 41 is arranged at the fire opening 23, the fire door 42 is slidably arranged on the door frame 41, the fire door driver 43 is used to drive the fire door 42 to slide relative to the shell 2 to open or close the fire opening 23, and the in-place detection element 44 is electrically connected to the fire door driver 43, and the in-place detection element 44 is used to detect whether the fire opening 23 is in an open or closed state.

[0085] Since the in-place detection element 44 is electrically connected to the fire door driver 43, when a fire occurs in the installation cavity 21 and the in-place detection element 44 detects that the fire opening 23 is in an open state, the fire door driver 43 can drive the fire door 42 to slide relative to the outer shell 2, so that the fire door 42 automatically covers the fire opening 23. In this way, the purpose of automatically and quickly closing the fire opening 23 can be achieved without the need for human intervention, and the fire can be further prevented from spreading through the fire opening 23 to the outside of the charging and discharging device 100 and threatening the personal safety of personnel.

[0086] Among them, the above-mentioned in-place detection element 44 may include but is not limited to an in-place sensor, and the above-mentioned fire door driving component 43 may include but is not limited to a cylinder, which is not limited in this embodiment.

[0087] It should be noted that the fire door 42 can be slidably disposed on the door frame 41 through a slide rail assembly, or can be slidably disposed on the door frame 41 through other methods, which is not limited in this embodiment.

[0088] In order to perform maintenance in time when an abnormality occurs in the installation cavity 21, in some embodiments, see Figure 2 The housing 2 is provided with a maintenance opening (not shown in the figure) communicating with the installation cavity 21, and a maintenance door 5 which can open or close the maintenance opening is provided at the maintenance opening.

[0089] By providing the maintenance door 5 , when an abnormality occurs in the installation cavity 21 , the maintenance opening can be opened through the maintenance door 5 in time to perform maintenance on the abnormality in the installation cavity 21 , making the maintenance of the charging and discharging device 100 easier.

[0090] Wherein, in some embodiments, see Figure 2 The maintenance door 5 and the fire door assembly 4 can be arranged relative to each other. Of course, in other embodiments, the maintenance door 5 and the fire door assembly 4 can also have other possible positional relationships, which is not limited in this embodiment.

[0091] The present application also provides a combined charging and discharging system 200, see Fig. 9The combined charging and discharging system 200 includes a plurality of charging and discharging devices 100 , and at least two of the plurality of charging and discharging devices 100 are stacked in a vertical direction.

[0092] Among them, the structure of the charging and discharging device 100 can be the same as the structure of the charging and discharging device 100 in any one of the above embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description of the charging and discharging device 100 in the above embodiments, and this embodiment does not limit this.

[0093] In this embodiment, since each charging and discharging device 100 can perform charging and discharging tests on the component to be tested, when the combined charging and discharging system 200 includes multiple charging and discharging devices 100, the combined charging and discharging system 200 can perform charging and discharging tests on multiple components to be tested at the same time, so the efficiency is higher.

[0094] In addition, since at least two of the multiple charging and discharging devices 100 are stacked in the vertical direction, the combined charging and discharging system 200 can fully utilize the space in the vertical direction, thereby achieving the effect of reducing the occupied area.

[0095] In addition, since the charging and discharging device 100 has the advantages of simple structure, reduced volume, reduced footprint, and reduced cost compared to the charging and discharging device 100 in the related art, when the combined charging and discharging system 200 includes the charging and discharging device 100, the structure of the entire combined charging and discharging system 200 can be simple, the footprint is small, and the cost is low.

[0096] In some embodiments, see Fig. 9 At least two of the multiple charging and discharging devices 100 are stacked in the vertical direction to form a first combination cabinet 2001, and the remaining charging and discharging devices 100 are stacked in the vertical direction to form a second combination cabinet 2002. The second combination cabinet 2002 and the first combination cabinet 2001 have a gap in the horizontal direction, and an electric box 2003 is arranged in the gap. The electric box 2003 is electrically connected to the multiple charging and discharging units 1 respectively.

[0097] Among them, since the above-mentioned electrical box 2003 is electrically connected to multiple charging and discharging units 1 respectively, the electrical box 2003 can supply power to multiple charging and discharging units 1 at the same time. In layman's terms, one electrical box 2003 can correspond to multiple charging and discharging units 1. Compared with the method of providing an electrical box 2003 for each charging and discharging unit 1, this method can make the electrical box 2003 more integrated and more conducive to maintenance.

[0098] In addition, since the electrical box 2003 is located in the gap between the second combined cabinet 2002 and the first combined cabinet 2001 in the horizontal direction, the second combined cabinet 2002 and the first combined cabinet 2001 can be arranged roughly around the electrical box 2003. In this way, the electrical box 2003 can be closer to the second combined cabinet 2002 and the first combined cabinet 2001. Therefore, the wires between the second combined cabinet 2002 and the electrical box 2003, and between the first combined cabinet 2001 and the electrical box 2003 can be shorter, thereby achieving the purpose of saving wires.

[0099] In some embodiments, see Fig. 9 and Fig.10 The combined charging and discharging system 200 further includes: a bottom bracket 2004 , and a plurality of charging and discharging devices 100 are all disposed on the bottom bracket 2004 and are all located above the bottom bracket 2004 .

[0100] Since the multiple charging and discharging devices 100 are all arranged on the bottom bracket 2004 and are all located above the bottom bracket 2004, it is possible to avoid the multiple charging and discharging devices 100 being directly in contact with the ground and damaged by moisture, thereby increasing the service life of the combined charging and discharging system 200.

[0101] Further, in order to facilitate the transport of the combined charging and discharging system 200, in some embodiments, see Fig. 9 and Fig.10 The bottom bracket 2004 matches the fork of the forklift. With such arrangement, when the combined charging and discharging system 200 needs to be transported, the fork of the forklift can be directly inserted into the bottom bracket 2004 for transport, making it convenient to transport the combined charging and discharging system 200.

[0102] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
