Description

Technical Field

[0001] The present invention relates to the technical field of battery production, and in particular to a battery charging and discharging device. Background Art

[0002] In the modern battery manufacturing industry, charging and discharging of newly produced or repaired batteries is an indispensable step. This process is not only used to activate the battery to achieve its best performance, but also a key link to detect the health of the battery and ensure that it meets quality standards. In order to achieve these purposes, specially designed battery charging and discharging devices are usually used.

[0003] Since the battery may experience thermal runaway or combustion during the charging and discharging process, in the related art, the battery charging and discharging device is provided with a fire-fighting pipeline, and when the battery burns or experiences thermal runaway, water is sprayed onto the battery to cool the battery and suppress the spread of thermal runaway or combustion.

[0004] However, the cooling efficiency of the battery by spraying is low, the cooling effect is poor, the coverage is small, and the cooling uniformity is poor, which may cause the temperature in some areas of the battery to be too high, causing further thermal runaway. Summary of the invention

[0005] In view of this, the present invention provides a battery charging and discharging device to solve or improve the problem that the spray cooling effect of the battery charging and discharging device in the related art is poor.

[0006] The present invention provides a battery charging and discharging device, comprising:

[0007] A frame assembly having a receiving space therein for receiving a battery assembly;

[0008] A support assembly, which is liftably disposed in the accommodation space and is used to support the battery assembly;

[0009] A charging assembly, disposed in the accommodation space and used to charge the battery assembly;

[0010] A storage box is arranged below the support assembly, and an opening is provided on the top of the storage box for the support assembly to pass through, and the storage box is used to store fire-fighting liquid;

[0011] The lifting drive device is connected to the supporting assembly and is used to drive the supporting assembly to enter and exit the containing box.

[0012] In the battery charging and discharging device provided by the present invention, when the battery assembly produces thermal runaway or combustion, the lifting drive device can drive the support assembly to descend into the containing box, so that the battery assembly on the support assembly can be synchronously descended into the containing box, so that the battery assembly is immersed in the fire-fighting liquid in the containing box, thereby quickly cooling the battery assembly, suppressing combustion and explosion, and preventing the spread of fire.

[0013] Compared with the spray cooling method, this setting can prevent the fire-fighting liquid from evaporating too quickly by immersing the battery assembly in the fire-fighting liquid, thereby improving the cooling efficiency and ensuring the cooling effect. In addition, it can increase the contact area between the battery assembly and the fire-fighting liquid, so that the battery assembly is cooled evenly, avoiding the problem of excessive temperature in some areas of the battery.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0033] Combine the following Figures 1 to 15 , describing the battery charging and discharging device provided in an embodiment of the present invention.

[0034] Specifically, the battery charging and discharging device includes a frame assembly 6 , a supporting assembly 7 , a charging assembly 8 , a containing box 20 and a lifting drive device 16 .

[0035] Among them, the frame assembly 6 is provided with a storage space for accommodating the battery assembly 5. Optionally, the frame assembly 6 includes a support frame 601 and a panel 602. For example, the support frame 601 includes a skeleton structure, and the skeleton structure can be formed by a profile. The panel 602 is connected to the skeleton structure and together with the skeleton structure, it encloses the storage space. Furthermore, at least part of the panel 602 is rotatably connected to the skeleton structure so that the cover can be rotated to open or close, thereby facilitating the installation or maintenance of the components in the storage space.

[0036] The support assembly 7 is movably disposed in the accommodating space and is used to support the battery assembly 5. Optionally, the support assembly 7 is slidably connected to the frame assembly 6.

[0037] The charging assembly 8 is disposed in the accommodating space and is used to charge the battery assembly 5 .

[0038] The containing box 20 is arranged below the supporting assembly 7. The top of the containing box 20 is provided with an opening for the supporting assembly 7 to pass through. The containing box 20 is used to store fire-fighting liquid, which includes but is not limited to water.

[0039] The lifting drive device 16 is connected to the supporting assembly 7 and is used to drive the supporting assembly 7 to enter and exit the containing box 20 .

[0040] In this embodiment, when the battery assembly 5 produces thermal runaway or combustion, the lifting drive device 16 can drive the support assembly 7 to descend into the containing box 20, so that the battery assembly 5 on the support assembly 7 can be synchronously descended into the containing box 20, so that the battery assembly 5 is immersed in the fire-fighting fluid in the containing box 20, thereby quickly cooling the battery assembly 5, suppressing combustion and explosion, and preventing the fire from spreading.

[0041] With such a configuration, compared with the spray cooling method, immersing the battery assembly 5 in the fire-fighting liquid can prevent the fire-fighting liquid from evaporating too quickly, thereby improving the cooling efficiency and ensuring the cooling effect. In addition, it can increase the contact area between the battery assembly 5 and the fire-fighting liquid, so that the battery assembly 5 is cooled evenly, avoiding the problem of excessive temperature in some areas of the battery 502.

[0042] refer to Figure 8 As shown, in some embodiments provided by the invention, the lifting drive device 16 includes a flexible member 1601 , a transmission wheel 1602 and a reciprocating drive mechanism 1603 .

[0043] The reciprocating drive mechanism 1603 includes a fixed end and a driving end. The fixed end of the reciprocating drive mechanism 1603 is connected to the frame assembly 6, and the driving end of the reciprocating drive mechanism 1603 is provided with a rotatable transmission wheel 1602, and the frame assembly 6 is also provided with a rotatable transmission wheel 1602.

[0044] One end of the flexible member 1601 is connected to the frame assembly 6 , and the other end passes through the transmission wheel 1602 on the driving end and the transmission wheel 1602 on the frame assembly 6 in sequence, and is connected to the support component 7 .

[0045] In this embodiment, when the reciprocating drive mechanism 1603 is extended, the support assembly 7 descends under the action of gravity. When the reciprocating drive mechanism 1603 is shortened, the reciprocating drive mechanism 1603 tightens the flexible member 1601 through the transmission wheel 1602, and the flexible member 1601 tensions the support assembly 7, so that the support assembly 7 rises.

[0046] With such arrangement, the reciprocating drive mechanism 1603 can drive the supporting assembly 7 in and out of the containing box 20 through the flexible member 1601 without arranging the reciprocating drive mechanism 1603 inside the containing box 20, thereby avoiding the problem of reduced capacity of the containing box 20 due to the space occupied by the reciprocating drive mechanism 1603.

[0047] In addition, placing the reciprocating drive mechanism 1603 outside the containing box 20 can make installation, maintenance and inspection work more convenient, reduce the difficulty and cost of maintenance, and prevent the liquid in the containing box 20 from damaging the reciprocating drive mechanism 1603.

[0048] refer to Figure 8 As shown, in some embodiments provided by the invention, the frame assembly 6 includes a support plate 6011. For example, the support plate 6011 is connected to the skeleton structure of the frame assembly 6.

[0049] The support assembly 7 is slidably connected to the support plate 6011 in the vertical direction. The support plate 6011 is provided with a through hole 104 for the support assembly 7 to pass through. For example, the upper end portion of the support assembly 7 can pass through the through hole 104 to support the battery assembly 5. The reciprocating drive mechanism 1603 is provided below the support plate 6011, and a transmission wheel 1602 is provided on the surface of the support plate 6011 facing the reciprocating drive mechanism 1603.

[0050] In this embodiment, the reciprocating drive mechanism 1603 can be disposed below the support plate 6011 , thereby avoiding the reciprocating drive mechanism 1603 from occupying the space above the support plate 6011 and making full use of the installation space below the support plate 6011 .

[0051] Optionally, the reciprocating drive mechanism 1603 is configured as a pneumatic cylinder, an oil cylinder or an electric cylinder.

[0052] Optionally, the flexible member 1601 is configured as a chain or a transmission belt. Correspondingly, the transmission wheel 1602 is a sprocket wheel or a belt wheel.

[0053] Optionally, there are two lifting drive devices 16 , and the two lifting drive devices 16 are respectively arranged on both sides of the support component 7 , so that the force of the support component 7 is balanced and the operation is stable.

[0054] In some embodiments provided by the invention, the battery charging and discharging device further includes a locking assembly 17 .

[0055] The locking assembly 17 is arranged on the frame assembly 6, for example, the locking assembly 17 is arranged on the support plate 6011, and the locking assembly 17 is retractable. The retracting direction of the locking assembly 17 intersects with the lifting direction of the support assembly 7. The locking assembly 17 is used to limit the support assembly 7 in the lifting direction of the support assembly 7 to limit the support assembly 7 from descending.

[0056] Specifically, when the support assembly 7 is raised to the position, the locking assembly 17 is extended to limit the descent of the support assembly 7. When the support assembly 7 needs to be lowered, the locking assembly 17 is retracted to release the position limit of the support assembly 7.

[0057] In this embodiment, the support assembly 7 is limited by the locking assembly 17 , so that the support assembly 7 has an accurate and stable position, so that the support assembly 7 can provide a more stable support effect for the battery assembly 5 .

[0058] In addition, the locking assembly 17 can bear the gravity of the support assembly 7. For example, under normal charging and discharging conditions, the lifting drive device 16 does not need to bear the load of the support assembly 7, thereby achieving an energy-saving effect.

[0059] Optionally, at least two locking assemblies 17 are provided on both sides of the support assembly 7, so that the force on the support assembly 7 is balanced.

[0060] refer to Figure 8 As shown, in some embodiments provided by the invention, the positioning assembly 15 includes a locking block 1701 and a locking drive mechanism 1702 .

[0061] Among them, the locking block 1701 is slidably arranged on the support plate 6011, and the sliding direction of the locking block 1701 intersects with the lifting direction of the support assembly 7. The locking block 1701 is used to limit the support assembly 7 in the lifting direction of the support assembly 7.

[0062] The locking drive mechanism 1702 is mounted on the support plate 6011 and is in transmission connection with the locking block 1701. The locking drive mechanism 1702 is used to drive the locking block 1701 to slide.

[0063] Optionally, the locking drive mechanism 1702 is configured as a pneumatic cylinder, an oil cylinder or an electric cylinder.

[0064] In some embodiments provided by the present invention, the battery charging and discharging device further includes a fire-fighting pipeline 18 and a fire-fighting nozzle 19 .

[0065] The fire sprinkler 19 is connected to the fire pipeline 18 , and the fire sprinkler 19 is arranged on one side of the support assembly 7 , and the spray port of the fire sprinkler 19 faces the direction of the support assembly 7 .

[0066] In this embodiment, by providing a fire-fighting pipe 18 and a fire-fighting nozzle 19, when the battery assembly 5 generates thermal runaway, fire-fighting liquid can be transported through the fire-fighting pipe 18, and the fire-fighting liquid can be sprayed toward the battery assembly 5 through the fire-fighting nozzle 19 to suppress thermal runaway or suppress smoke diffusion.

[0067] With such a configuration, the temperature rise of the battery assembly 5 can be suppressed through the combined effects of immersion and spraying. At the same time, since it takes a certain amount of time for the support assembly 7 to descend, and the opening time of the fire-fighting pipeline 18 is relatively short, the fire-fighting liquid can always be sprayed by the fire-fighting nozzle 19 during the descent of the support assembly 7, thereby avoiding the problem of violent combustion of the battery assembly 5 during the descent of the support assembly 7.

[0068] Alternatively, the fire fighting liquid may be water or fire fighting foam.

[0069] Optionally, the battery charging and discharging device further includes a control system. The fire-fighting pipeline 18 is electrically connected to the control system. It can be understood that the control valve in the fire-fighting pipeline 18 is electrically connected to the control system.

[0070] The control system controls the fire protection pipe 18 to open based on at least one of the ambient temperature and the operating temperature of the battery assembly 5. For example, when the operating temperature or the ambient temperature is too high, the surface battery assembly 5 may have a thermal runaway problem, and the control system can open the fire protection pipe 18.

[0071] Furthermore, the battery charging and discharging device also includes a smoke detection device. The smoke detection device can be arranged above the support assembly 7 and is used to detect smoke information in the accommodation space. The smoke detection device is electrically connected to the control system. Based on the smoke information, the control system controls the fire protection pipeline 18 to open when it determines that smoke is generated.

[0072] Optionally, the lifting drive device 16 and the fire-fighting pipeline 18 are both electrically connected to the control system.

[0073] The control system controls the lifting drive device 16 to drive the support assembly 7 to descend and the fire fighting pipe 18 to open based on at least one of the ambient temperature in the accommodation space, the operating temperature of the battery assembly 5, and the smoke information. For example, when the ambient temperature or the operating temperature is too high, or smoke is generated in the accommodation space, the control system controls the lifting drive device 16 to drive the support assembly 7 to descend.

[0074] In this embodiment, the lifting drive device 16 can cooperate with the fire-fighting pipeline 18. For example, when the ambient temperature or the working temperature is too high, or smoke is generated in the storage space, the control system controls the fire-fighting pipeline 18 to open, so that the fire-fighting nozzle 19 sprays the battery assembly 5 with fire-fighting liquid to cool down and suppress smoke, and at the same time controls the lifting drive device 16 to drive the support assembly 7 to descend, so as to immerse the battery assembly 5 in the fire-fighting liquid in the storage box 20.

[0075] With such a configuration, the temperature rise of the battery assembly 5 can be suppressed through the combined effects of immersion and spraying. At the same time, since it takes a certain amount of time for the support assembly 7 to descend, and the opening time of the fire-fighting pipeline 18 is relatively short, the fire-fighting liquid can always be sprayed by the fire-fighting nozzle 19 during the descent of the support assembly 7, thereby avoiding the problem of violent combustion of the battery assembly 5 during the descent of the support assembly 7.

[0076] refer to Figure 4 as well as Figure 12-Figure 15 As shown, in some embodiments provided by the present invention, the battery charging and discharging device also includes a battery probe positioning mechanism.

[0077] The battery probe positioning mechanism is disposed on one side of the support assembly 7 and is used to dock with the battery assembly 5. For example, the battery probe positioning mechanism is used to be electrically connected to the charging assembly 8 for charging the battery assembly 5, or the battery probe positioning mechanism is used to be electrically connected to the load for discharging the battery assembly 5. The third airflow driving device 11 is disposed on a side of the battery probe positioning mechanism that is away from the support assembly 7.

[0078] In this embodiment, a battery probe positioning mechanism is provided to dock with the battery assembly 5 , so that the battery assembly 5 can be charged and discharged through the battery probe positioning mechanism.

[0079] refer to Figure 3-Figure 6 As shown, in some embodiments provided by the present invention, corresponding battery probe positioning mechanisms are provided on both sides of the support assembly 7 along the second direction Y. In this way, the two battery probe positioning mechanisms can respectively abut against the poles at both ends of the battery 502, so that the charging and discharging device is suitable for the battery 502 with the positive and negative poles distributed at both ends of the battery 502.

[0080] In some embodiments provided by the present invention, reference Figure 4 As shown, the battery charging and discharging device also includes a restraining device 14 and a positioning component 15.

[0081] Among them, the restraint device 14 and the positioning assembly 15 are distributed on both sides of the support assembly 7, for example, along the first direction X, the restraint device 14 and the positioning assembly 15 are distributed on both sides of the support assembly 7. The positioning assembly 15 can be raised and lowered, for example, the positioning assembly 15 can be raised and lowered along the third direction Z. The restraint device 14 can be retracted and used to squeeze the battery assembly 5 in the direction where the positioning assembly 15 is located. For example, the restraint device 14 can be retracted along the first direction X. The first direction X, the second direction Y and the third direction Z intersect each other, for example, the three are perpendicular to each other.

[0082] In this embodiment, after the battery assembly 5 is placed on the support assembly 7, the restraint device 14 can be extended and squeezed in the direction of the positioning assembly 15. The restraint device 14 and the positioning assembly 15 restrain the battery assembly 5 together to prevent the battery assembly 5 from bulging.

[0083] Since the charging assembly 8 is disposed on the top of the supporting assembly 7 and the battery probe positioning mechanisms are disposed on both sides, the positioning assembly 15 can be raised and lowered so that the positioning assembly 15 can avoid the battery assembly 5 to facilitate the taking and placing of the battery assembly 5 .

[0084] For example, before placing the battery assembly 5, the positioning assembly 15 is first raised, and then the battery assembly 5 is placed on the support assembly 7, and then the positioning assembly 15 is lowered so that the positioning assembly 15 can cooperate with the restraining device 14 to restrain the battery assembly 5. After charging and discharging are completed, the positioning assembly 15 is raised again to facilitate taking out the battery assembly 5 through the position where the positioning assembly 15 is located.

[0085] In some embodiments provided by the invention, the positioning assembly 15 includes a positioning block and a positioning drive mechanism 1502 .

[0086] The support plate 6011 is provided with a guide rail extending in the vertical direction, and the positioning block is slidably matched with the guide rail. The positioning block and the restraining device 14 can restrain the battery assembly 5 together.

[0087] The positioning drive mechanism 1502 is connected to the positioning block and is used to drive the positioning block to slide. For example, the fixed end of the positioning drive mechanism 1502 is connected to the guide rail, and the driving end of the positioning drive mechanism 1502 is connected to the positioning block. For example, the positioning drive mechanism 1502 is arranged above the positioning block.

[0088] In this embodiment, the positioning block is driven to rise and fall by the positioning drive mechanism 1502 , so that the positioning block can avoid the battery assembly 5 and cooperate with the restraint device 14 to restrain the battery assembly 5 .

[0089] Optionally, the positioning drive mechanism 1502 is configured as a pneumatic cylinder, an oil cylinder or an electric cylinder.

[0090] refer to Fig. 9 As shown, in some embodiments provided by the invention, the support assembly 7 includes a lifting seat 701 and a support seat 702 .

[0091] The lifting seat 701 is slidably connected to the frame assembly 6 along the vertical direction. For example, the lifting seat 701 is slidably connected to the support plate 6011 of the frame assembly 6 along the vertical direction. Further, the lifting seat 701 is connected to the lifting drive device 16, and the locking assembly 17 is used to limit the lifting seat 701.

[0092] The support base 702 is slidably disposed on the lifting base 701 and is used to support the battery assembly 5. For example, the support base 702 is slidably disposed on the top of the lifting base 701 along the first direction X.

[0093] In this embodiment, the support seat 702 is slidably matched with the lifting seat 701, and the support seat 702 is used to support the battery assembly 5. During the process of the restraint device 14 pushing the battery assembly 5, the battery assembly 5 drives the support seat 702 to slide relative to the lifting seat 701, thereby avoiding friction between the battery assembly 5 and the support assembly 7, or avoiding obstruction or interference of the support assembly 7 on the battery assembly 5, so that the battery assembly 5 can run smoothly under the action of the restraint device 14.

[0094] Optionally, a retaining protrusion for limiting the position of the battery assembly 5 may be provided on the support seat 702 so that the battery assembly 5 has an accurate position on the support seat 702 .

[0095] Optionally, the support assembly 7 further comprises an elastic member, which connects the support seat 702 and the lifting seat 701. The elastic member is used to drive the support seat 702 to slide in a direction close to the restraint device 14.

[0096] In this embodiment, when the restraint device 14 drives the battery assembly 5 to operate, the battery assembly 5 drives the support seat 702 to slide away from the restraint device 14 until the battery assembly 5 stops against the positioning assembly 15. During this process, the support seat 702 causes the elastic member to deform.

[0097] After the charge and discharge are completed, the restraint device 14 is reset and the elastic member resumes its deformation, thereby driving the support seat 702 and the battery assembly 5 to move in a direction away from the positioning assembly 15, so that the battery assembly 5 is separated from the positioning assembly 15, avoiding interference or friction between the positioning assembly 15 and the battery assembly 5 during the lifting process, so that the positioning assembly 15 can be lifted and lowered stably.

[0098] Optionally, the elastic member is configured as a spring or a tension spring.

[0099] In some embodiments provided by the present invention, the restraint device 14 includes a support, a screw 1401 , a gear 1402 , a motor 1403 , a drive block 1405 , a clamping block 1406 , a clamping rod 1407 and a pressure sensor 1408 .

[0100] The support can be installed on the support plate 6011. The lead screw 1401 is rotatably connected to the support, the gear 1402 is sleeved on the lead screw 1401, and the motor 1403 is installed on the support and is transmission-connected to the gear 1402.

[0101] The driving block 1405 and the pressing block 1406 are both slidably mounted on the support along the first direction X, the driving block 1405 is arranged on the side of the pressing block 1406 away from the support assembly 7, and the driving block 1405 is threadedly matched with the lead screw 1401. The pressure sensor 1408 is arranged between the driving block 1405 and the pressing block 1406, and is connected to the driving block 1405 and the pressing block 1406 respectively.

[0102] There are multiple clamping rods 1407 , one end of which is connected to the clamping block 1406 , and the other end of which extends toward the direction of the support assembly 7 . The clamping rod 1407 is used to abut against the battery assembly 5 and abut against the battery assembly 5 .

[0103] In this embodiment, the motor 1403 drives the lead screw 1401 to rotate through the gear 1402 , and the lead screw 1401 drives the driving block 1405 to slide. The driving block 1405 drives the pressing block 1406 to slide through the pressure sensor 1408 , and the pressing block 1406 presses the battery assembly 5 through the pressing rod 1407 .

[0104] A pressure sensor 1408 is provided between the driving block 1405 and the pressing block 1406 so as to accurately obtain the magnitude of the force exerted by the restraining device 14 on the battery assembly 5 .

[0105] Optionally, there are two lead screws 1401, and the threads of the two lead screws 1401 are in opposite directions. The two lead screws 1401 are provided with corresponding gears 1402, and the gears 1402 on the two lead screws 1401 are identical and mesh with each other. The two lead screws 1401 are threadedly matched with the driving block 1405. In this embodiment, the driving block 1405 can be driven by the two lead screws 1401 at the same time, so that the driving block 1405 can run more smoothly.

[0106] In some embodiments provided by the present invention, the charging assembly 8 is arranged above the supporting assembly 7, and there is a gap between the charging assembly 8 and the supporting assembly 7 to accommodate the battery assembly 5. A first airflow driving device 801 is provided at one end of the charging assembly 8 close to the supporting assembly 7, and the air inlet side of the first airflow driving device 801 faces the supporting assembly 7. That is, the airflow driving direction of the first airflow driving device 801 is arranged from the supporting assembly 7 to the charging assembly 8. Optionally, the first airflow driving device 801 can be a fan.

[0107] Furthermore, the battery 502 charging device also includes a heat exchange device 9 , a second airflow driving device 10 and a third airflow driving device 11 .

[0108] The heat exchange device 9 is arranged in the accommodation space, and the heat exchange device 9 is located on one side of the support assembly 7. The heat exchange device 9 is used to exchange heat between the airflow and the refrigerant to cool the airflow. Optionally, the heat exchange device 9 is set as a gas-liquid heat exchanger or an air-to-gas heat exchanger. The refrigerant includes but is not limited to water. Optionally, the heat exchange device 9 can be connected to the frame assembly 6.

[0109] The second airflow driving device 10 is disposed above the heat exchange device 9, and the air outlet side of the second airflow driving device 10 faces the heat exchange device 9. The second airflow driving device 10 is used to drive the airflow to flow through the heat exchange device 9 so that the heat exchange device 9 absorbs the heat of the airflow. Optionally, the second airflow driving device 10 can be a fan.

[0110] The third airflow driving device 11 is disposed on a side of the heat exchange device 9 away from the second airflow driving device 10, and the air outlet side of the third airflow driving device 11 faces the support assembly 7, so that the third airflow driving device 11 drives the airflow discharged from the heat exchange device 9 to the position of the support assembly 7, thereby cooling the battery assembly 5 on the support assembly 7. Optionally, the third airflow driving device 11 may be a fan.

[0111] refer to Figure 2 The arrow in represents the direction of airflow. In this embodiment, after the battery assembly 5 on the support assembly 7 generates heat, the airflow naturally rises. At the same time, under the suction action of the first airflow driving device 801, the airflow flows through the charging assembly 8 and cools the charging assembly 8. At this time, the hot air accumulates at the top of the accommodation space. Under the action of the second airflow driving device 10, the air at the top of the accommodation space flows through the heat exchange device 9 and exchanges heat with the heat exchange device 9 to cool down. The low-temperature air discharged from the heat exchange device 9 is driven by the third airflow driving device 11 and is blown to the battery assembly 5 on the support assembly 7, thereby cooling the battery assembly 5, thus forming an airflow cycle.

[0112] With such an arrangement, air circulation is performed by utilizing the naturally rising hot air flow in combination with the first airflow driving device 801, so that effective cooling can be achieved without significantly increasing energy consumption. In addition, the first airflow driving device 801 draws the airflow where the battery assembly 5 is located. On the one hand, it can fully utilize the cooling capacity provided by the heat exchange device 9 to improve the cooling capacity utilization rate. On the other hand, it can speed up the airflow velocity where the battery assembly 5 is located and speed up the cooling rate of the battery assembly 5.

[0113] The hot air accumulated at the top of the accommodation space can be guided to the heat exchange device 9 for cooling by the second airflow driving device 10, thereby preventing the overall temperature in the accommodation space from being too high and affecting the battery assembly 5 or other electrical components.

[0114] By means of the heat exchange device 9 disposed in the accommodation space, the heat in the accommodation space can be conducted away through the circulation of the refrigerant, and the heat exchange device 9 can maintain high efficiency in different working environments and is not easily affected by changes in external temperature. Moreover, compared with the form of forced ventilation by a fan, by conducting the heat away from the accommodation space through the heat exchange device 9, dust will not be brought into the accommodation space, thus preventing the dust from affecting the electrical components.

[0115] The air cooled by the heat exchange device 9 can be redirected to the battery assembly 5 through the third airflow driving device 11, so that the airflow in the accommodating space forms a closed-loop system, thereby improving the utilization rate of cold energy and reducing heat exchange with the external environment, so that the equipment is not affected by external temperature fluctuations.

[0116] refer to Figure 2 As shown, in some embodiments provided by the present invention, the number of support assemblies 7 is at least two. For example, the following description will be based on the number of support assemblies 7 being two. Each support assembly 7 is provided with a corresponding charging assembly 8, a second airflow driving device 10 and a third airflow driving device 11.

[0117] There is a heat exchange device 9 between two adjacent support assemblies 7. The second airflow driving devices 10 of the two adjacent support assemblies 7 are both arranged above the heat exchange device 9, and the air outlet side of the second airflow driving devices 10 faces the heat exchange device 9.

[0118] The third airflow driving devices 11 of two adjacent supporting assemblies 7 are both arranged below the heat exchange device 9 , and the third airflow driving devices 11 face the corresponding supporting assemblies 7 , respectively.

[0119] In this embodiment, by providing at least two support components 7, and each support component 7 has a corresponding charging component 8, the battery charging and discharging device can perform charging and discharging operations for at least two battery components 5 at the same time, thereby improving the working efficiency of the battery charging and discharging device.

[0120] In addition, by arranging the second airflow driving devices 10 of two adjacent support assemblies 7 above the heat exchange device 9 and the third airflow driving devices 11 of two adjacent support assemblies 7 below the heat exchange device 9, the battery assemblies 5 on the two adjacent support assemblies 7 can use the common heat exchange device 9, thereby reducing the number of parts and costs, and making the overall battery charging and discharging device more compact, maximizing the use of available space.

[0121] refer to Figure 2 and Figure 3 As shown, in some embodiments provided by the present invention, the second airflow driving devices 10 of two adjacent support assemblies 7 are both installed on the heat exchange device 9, and the second airflow driving devices 10 of two adjacent support assemblies 7 are connected. For example, along the driving airflow direction of the third airflow driving device 11 (i.e. Figure 2 One side of the second airflow driving device 10 is connected to the heat exchange device 9, and the other side is connected to another second airflow driving device 10.

[0122] In this embodiment, by installing the two second airflow driving devices 10 on the heat exchange device 9, the second airflow driving devices 10 and the heat exchange device 9 are more compact, which helps to save space in the accommodation space.

[0123] By connecting the two second airflow driving devices 10 , the connection strength and rigidity between the second airflow driving devices 10 and the heat exchange device 9 can be improved, thereby improving the stability of the two second airflow driving devices 10 installed on the heat exchange device 9 .

[0124] refer to Figure 2 and Figure 3 As shown, in some embodiments provided by the present invention, the battery charging and discharging device further includes a connecting rod 12.

[0125] The third airflow driving devices 11 of two adjacent support assemblies 7 are arranged at intervals and installed on the frame assembly 6, for example, the air outlet end of the heat exchange device 9 faces the gap between the two third airflow driving devices 11. The connecting rod 12 is connected between the third airflow driving devices 11 of two adjacent support assemblies 7.

[0126] In this embodiment, the two third airflow driving devices 11 are connected by a connecting rod 12 to improve the connection strength and rigidity between the third airflow driving devices 11 and the frame assembly 6 , thereby improving the installation stability of the two third airflow driving devices 11 .

[0127] refer to Figure 2 and Figure 3As shown, in some embodiments provided by the present invention, along the airflow driving direction of the third airflow driving device 11, the side of the second airflow driving device 10 close to the support assembly 7 is connected to the heat exchange device 9, and the side of the second airflow driving device 10 away from the support assembly 7 is inclined in the direction away from the heat exchange device 9. It can be understood that the airflow driving direction of the third airflow driving device 11 is Figure 2 The left and right direction in .

[0128] like Figure 2 In the figure, after the first airflow driving device 801 discharges the airflow, the airflow contacts the top arm of the accommodating space and then runs in the left and right directions in the figure. If the second airflow driving device 10 is set completely horizontally, the airflow running direction at the top of the accommodating space is perpendicular to the airflow driving direction of the second airflow driving device 10, resulting in a poor airflow driving effect of the second airflow driving device 10.

[0129] In this embodiment, by connecting the side of the second airflow driving device 10 close to the support assembly 7 to the heat exchange device 9, and the side of the second airflow driving device 10 away from the support assembly 7 is inclined in the direction away from the heat exchange device 9, the air inlet of the second airflow driving device 10 is closer to being parallel to the flow direction of the top airflow, that is, the airflow does not need to change direction significantly to enter the second airflow driving device 10, thereby reducing the resistance of the airflow when entering.

[0130] refer to Figure 2 and Figure 3 As shown, in some embodiments provided by the present invention, the battery charging and discharging device further includes a guide plate 13.

[0131] The guide plate 13 is located on the air inlet side of the second airflow driving device 10, and along the airflow driving direction of the third airflow driving device 11, one end of the guide plate 13 is arranged on the side of the second airflow driving device 10 away from the support assembly 7, and the other end of the guide plate 13 is inclined toward the side where the support assembly 7 is located and is connected to the inner wall of the accommodating space.

[0132] In this embodiment, a guide plate 13 is provided, and one end of the guide plate 13 is provided at the second airflow driving device 10, and the other end is inclined toward the support assembly 7 and connected to the inner wall of the accommodating space. In this way, on the one hand, the barrier effect of the guide plate 13 can prevent the heat at the top of the accommodating space from leaking through the second airflow driving device 10 and the inner wall of the accommodating space, thereby ensuring that most of the heat can be driven by the second airflow driving device 10 to the heat exchange device 9, thereby improving the cooling effect.

[0133] On the other hand, through the guiding effect of the guide plate 13, during the airflow running at the top of the accommodating space, after contacting the guide plate 13, the air can enter the second airflow driving device 10 along the guide plate 13. This directional guide can significantly improve the airflow capture efficiency and ensure that more hot air can be processed in time.

[0134] In some embodiments provided by the present invention, the battery charging and discharging device includes a temperature detection device and a control system.

[0135] The temperature detection device is used to detect at least one of the ambient temperature in the accommodation space and the operating temperature of the battery assembly 5. The temperature detection device, the first airflow driving device 801, the second airflow driving device 10 and the third airflow driving device 11 are all electrically connected to the control system.

[0136] The control system controls the power of at least one of the first airflow driving device 801 , the second airflow driving device 10 , and the third airflow driving device 11 based on at least one of the ambient temperature and the operating temperature.

[0137] In this embodiment, the ambient temperature in the accommodation space and the operating temperature of the battery assembly 5 can be detected by the temperature detection device, so that the power of at least one of the first airflow driving device 801, the second airflow driving device 10 and the third airflow driving device 11 is controlled and adjusted according to the ambient temperature and the operating temperature, so that the ambient temperature and the operating temperature are maintained within a constant range, so that the electrical components and the battery assembly 5 in the accommodation space can be in an adapted working environment, thereby improving their stability.

[0138] Optionally, the temperature detection device includes a first temperature sensor for detecting the ambient temperature, and a second temperature sensor for detecting the operating temperature of the battery assembly 5. Both the first temperature sensor and the second temperature sensor are electrically connected to the control system.

[0139] refer to Figure 4 as well as Figure 12-Figure 15 As shown, in some embodiments provided by the present invention, the battery probe positioning mechanism includes a fixing seat 1 and a positioning unit 2. The fixing seat 1 can be set on the support plate 6011 of the frame assembly 6. The number of the positioning units 2 is at least two, and at least two positioning units 2 are arranged in sequence along the first direction X. It can be understood that the batteries 502 in the battery assembly 5 are also distributed along the first direction X.

[0140] The positioning units 2 each include a sliding seat 201 , a probe assembly 202 , a driving assembly 203 and a guiding assembly 204 .

[0141] There are two sliding seats 201, and the two sliding seats 201 are slidably connected to the fixed seat 1 along the first direction X. Optionally, the fixed seat 1 is provided with guide rails corresponding to the sliding seats 201 one by one, and the sliding seats 201 are slidably connected to the corresponding guide rails.

[0142] The probe assembly 202 is slidably connected to the two sliding seats 201 along the second direction Y. Optionally, the two sliding seats 201 are distributed on opposite sides of the probe assembly 202 and are both slidably connected to the probe assembly 202. The second direction Y intersects with the first direction X, for example, the two are perpendicular. The probe assembly 202 is used to dock with the battery assembly 5. Specifically, the pole of the battery 502 in the battery assembly 5 is docked with the probe assembly 202.

[0143] There are two drive assemblies 203, and the two drive assemblies 203 are respectively arranged on the corresponding sliding seats 201. Optionally, the two drive assemblies 203 are arranged on the corresponding sliding seats 201 in a one-to-one correspondence. Both drive assemblies 203 are connected to the probe assembly 202, and the drive assembly 203 is used to drive the probe assembly 202 to slide, so that the probe assembly 202 can dock or detach with the battery assembly 5. The two drive assemblies 203 jointly drive the probe assembly 202 to slide.

[0144] The guide assembly 204 is disposed on the probe assembly 202, and the guide assembly 204 is provided with a positioning groove 2041. The positioning groove 2041 is used to dock with the positioning protrusion 501 on the battery assembly 5. For example, the positioning groove 2041 faces the battery assembly 5.

[0145] In this embodiment, during use, the two driving components 203 jointly drive the probe component 202 to move in the direction close to the battery component 5, and the positioning groove 2041 of the guide component 204 docks with the positioning protrusion 501 on the battery component 5. During the alignment of the positioning protrusion 501 and the positioning groove 2041, the guide component 204 drives the probe component 202 and the sliding seat 201 to slide on the fixed seat 1, so that the probe component 202 is aligned with the battery pole of the battery component 5.

[0146] With such arrangement, the probe assemblies 202 are slidably connected to the fixed seat 1 via the corresponding sliding seat 201, so that each probe assembly 202 can adjust its position in the direction in which the batteries 502 are arranged, so that each probe assembly 202 can adapt to the corresponding battery 502 position, thereby reducing the problem of the probe assembly 202 being unable to accurately dock with the battery 502 due to processing errors, assembly errors, and expansion of the battery 502.

[0147] In addition, since each probe assembly 202 is driven by a corresponding driving assembly 203, the movements of the probe assemblies 202 will not affect each other, so that the probe assemblies 202 can move in sequence, so that after the previous probe assembly 202 is extended and accurately docked, the next probe assembly 202 is extended and docked, ensuring that each probe assembly 202 has an accurate position.

[0148] In addition, the probe assembly 202 is slidably connected to the two sliding seats 201, which can improve the sliding stability of the probe assembly 202. The driving assembly 203 on the two sliding seats 201 jointly drives the probe assembly 202, so that the force on the probe assembly 202 is balanced and the operation is smooth, and there is sufficient insertion and extraction force between the probe assembly 202 and the battery assembly 5.

[0149] refer to Fig.15 As shown, in some embodiments provided by the present invention, the guide assembly 204 includes a guide block 2042 and an elastic member.

[0150] The guide block 2042 is slidably connected to the probe assembly 202 along the second direction Y. For example, the probe assembly 202 is provided with a guide rail extending along the second direction Y, and the guide hole is slidably connected to the guide rail. A positioning groove 2041 is provided on the guide block 2042 .

[0151] The elastic member is disposed between the guide block 2042 and the probe assembly 202, and is used to drive the guide block 2042 to slide toward the direction close to the battery assembly 5. For example, the elastic member is configured as a spring, and both ends of the spring are respectively against the guide hole and the probe assembly 202.

[0152] In this embodiment, the guide block 2042 is slidably connected to the probe assembly 202, and the elastic member drives the guide block 2042 to slide in the direction close to the battery assembly 5. After the positioning protrusion 501 is inserted into the positioning groove 2041, the guide block 2042 can compress the elastic member and slide relative to the probe assembly 202 to avoid the guide block 2042 contacting the positioning protrusion 501, thereby preventing the probe assembly 202 from sliding in the direction close to the battery assembly 5.

[0153] In addition, after the probe assembly 202 is separated from the battery assembly 5, the guide block 2042 can be reset under the action of the elastic member so as to facilitate docking with the positioning protrusion 501 of the battery assembly 5 next time.

[0154] In some embodiments provided by the present invention, the guide assembly 204 further includes a guide wheel 2043. The positioning groove 2041 is configured as a V-shaped groove, and a rotatable guide wheel 2043 is disposed on both sides of the positioning groove 2041. The outer circumferential surface of the guide wheel 2043 protrudes from the side wall of the positioning groove 2041. Accordingly, the positioning protrusion 501 is configured as a V-shaped protrusion or a trapezoidal protrusion.

[0155] In this embodiment, by setting the positioning groove 2041 as a V-shaped groove, the V-shaped groove, when used in conjunction with the V-shaped protrusion or the trapezoidal protrusion, can provide an automatic centering function, thereby ensuring the accuracy of docking.

[0156] In addition, since the guide wheel 2043 is rotatable and its outer circumferential surface protrudes from the side wall of the positioning groove 2041, the sliding friction between the positioning groove 2041 and the positioning protrusion 501 can be significantly reduced and converted into rolling friction, thereby reducing wear and improving durability.

[0157] refer to Fig.14 and Fig.15 As shown, in some embodiments provided by the present invention, two sliding seats 201 are arranged along the third direction Z, and the third direction Z, the first direction X and the second direction Y intersect each other. For example, the third direction Z, the first direction X and the second direction Y are perpendicular to each other.

[0158] In the third direction Z, the probe assembly 202 is disposed between the two sliding seats 201 . Accordingly, the two driving assemblies 203 are respectively disposed on the two sliding seats 201 , and thus, the two driving assemblies 203 are also distributed on two opposite sides of the probe assembly 202 .

[0159] In this embodiment, two sliding seats 201 and two driving components 203 are arranged on both sides of the probe component 202, so that the size of the battery probe positioning mechanism in the third direction Z can be fully utilized, and the travel path of the driving component 203 is arranged in parallel with the travel path of the probe component 202, thereby reducing the size of the battery probe positioning mechanism in the second direction Y, improving the compactness of the battery probe positioning mechanism in the second direction Y, and thus reducing the footprint of the battery probe positioning mechanism.

[0160] refer to Fig.15 As shown, in some embodiments provided by the present invention, the driving component 203 includes a fixed end and a driving end slidably connected to the fixed end.

[0161] The fixed end is connected to a side of the sliding seat 201 close to the battery assembly 5 , and the driving end is arranged in a direction away from the battery assembly 5 and connected to the probe assembly 202 .

[0162] In this embodiment, the travel path of the driving component 203 and the travel path of the probe component 202 are arranged in parallel, so as to reduce the size of the battery probe positioning mechanism in the second direction Y, improve the compactness of the battery probe positioning mechanism in the second direction Y, and thus reduce the footprint of the battery probe positioning mechanism.

[0163] Optionally, the driving assembly 203 includes a pneumatic cylinder, an oil cylinder or an electric cylinder. Accordingly, the driving end is configured as a driving rod, and the fixed end is configured as a cylinder body.

[0164] In some embodiments provided by the present invention, the fixing base 1 includes a bottom plate 101 , a vertical plate 102 and a lifting plate 103 .

[0165] There are two vertical plates 102 , both of which extend along the third direction Z and are connected to the bottom plate 101 . For example, the vertical plates 102 are screwed or welded to the bottom plate 101 .

[0166] The lifting plate 103 is extended along the third direction Z, and the lifting plate 103 is connected to the two vertical plates 102 in an adjustable manner along the third direction Z. Specifically, both ends of the lifting plate 103 are connected to the two vertical plates 102 in an adjustable manner along the third direction Z.

[0167] The sliding seats 201 are all slidably connected to the lifting plate 103 .

[0168] In this embodiment, by connecting the two vertical plates 102 with the bottom plate 101, the fixing base 1 can be formed into a whole through the bottom plate 101. By connecting the lifting plate 103 with the two vertical plates 102, the lifting plate 103 is more stable.

[0169] By making the lifting plate 103 adjustable along the third direction Z, the position height of the probe assembly 202 can be adjusted by adjusting the position of the lifting plate 103 in the third direction Z, so that the position height of the probe assembly 202 is adapted to the position height of the battery 502 pole of the battery assembly 5.

[0170] refer to Fig.14 As shown, optionally, the battery probe positioning mechanism further includes a locking bolt 106. A waist-shaped hole 105 extending along the third direction Z is provided on the vertical plate 102, and the waist-shaped hole 105 penetrates the vertical plate 102 along the first direction X. The locking bolt 106 passes through the waist-shaped hole 105 and is threadedly connected to the lifting plate 103. In this way, the position of the lifting plate 103 can be adjusted after loosening the locking bolt 106.

[0171] Optionally, a guide groove is provided on the vertical plate 102, the guide groove extends along the third direction Z, the notch of the guide groove faces the lifting plate 103, and the lifting plate 103 is slidably matched with the guide groove. This arrangement allows the lifting plate 103 to be limited in the second direction Y by the guide groove.

[0172] Optionally, the battery probe positioning mechanism further includes a positioning bolt 107. The positioning bolt 107 extends along the third direction Z and is threadedly connected to the vertical plate 102. For example, a threaded seat may be installed on the vertical plate 102, and the positioning bolt 107 is threadedly connected to the threaded seat.

[0173] The positioning bolt 107 is used to abut against one end of the lifting plate 103 close to the bottom plate 101 and limit the lifting plate 103 in the third direction Z.

[0174] In this embodiment, the positioning bolt 107 is abutted against the lifting plate 103, so that the problem of the lifting plate 103 moving downward due to vibration or gravity can be prevented, and the position of the lifting plate 103 is ensured to be accurate. By threading the positioning bolt 107 with the vertical plate 102, the position of the positioning bolt 107 can be adapted to the position of the lifting plate 103 by screwing the positioning bolt 107.

[0175] Of course, in some embodiments not shown, the lifting plate 103 can also be lifted and lowered by the drive of a pneumatic cylinder, an oil cylinder or an electric cylinder.

[0176] In some embodiments provided by the present invention, a through hole 104 is provided on the lifting plate 103, and along the third direction Z, two sliding seats 201 are distributed on both sides of the through hole 104, and the sliding seats 201 are both provided on a side of the lifting plate 103 close to the battery assembly 5. Accordingly, the fixing portion 2031 of the driving assembly 203 is connected to a side of the sliding seat 201 close to the battery assembly 5.

[0177] The probe assembly 202 is disposed in the through hole 104, and one end of the probe assembly 202 away from the battery assembly 5 is connected to the driving assembly 203. Specifically, one end of the probe assembly 202 away from the battery assembly 5 is connected to the driving part 2032 of the driving assembly 203.

[0178] In this embodiment, two sliding seats 201 and two driving components 203 are arranged on both sides of the through opening 104, and the probe component 202 is passed through the through opening 104, so that the size of the battery probe positioning mechanism in the third direction Z can be fully utilized, and the travel path of the driving component 203 and the travel path of the probe component 202 are arranged in parallel, so as to reduce the size of the battery probe positioning mechanism in the second direction Y, improve the compactness of the battery probe positioning mechanism in the second direction Y, and thus reduce the footprint of the battery probe positioning mechanism.

[0179] refer to Fig.15 As shown, in some embodiments provided by the present invention, the probe assembly 202 includes a mounting seat 2021 and a probe 2022. The mounting seat 2021 is connected to the two sliding seats 201, and the probe 2022 is arranged on a side of the mounting seat 2021 close to the battery assembly 5.

[0180] In some embodiments provided by the present invention, the battery probe positioning mechanism further includes a reset drive device 3 and a positioning structure 4 .

[0181] The reset drive device 3 and the positioning structure 4 are both installed on the fixed seat 1. At least two positioning units 2 are arranged along the first direction X to form a queue. The reset drive device 3 is located at one end of the queue formed by the positioning units 2, and the positioning structure 4 is located at the other end of the queue. The reset drive device 3 is used to drive the queue to slide toward the positioning structure 4.

[0182] Since the positioning groove 2041 cooperates with the positioning protrusion 501 during the charging and discharging process of the battery assembly 5, the gap between the positioning units 2 changes. In this embodiment, after the charging and discharging of the battery assembly 5 is completed, the positioning unit 2 can be driven by the reset drive device 3, and the positioning unit 2 will abut against the positioning structure 4 in turn and finally abut against the positioning structure 4, so that all the positioning units 2 can be reset to the initial position to facilitate the next docking with the battery assembly 5.

[0183] Optionally, the reset drive device 3 is configured as a pneumatic cylinder, an oil cylinder or an electric cylinder.

[0184] refer to Fig. 9 As shown, in some embodiments provided by the invention, the battery assembly 5 includes a tray 503 and a plurality of batteries 502 disposed on the tray 503. The plurality of batteries 502 are arranged in sequence on the tray 503, for example, in the charging and discharging state, the plurality of batteries 502 are arranged along the first direction X.

[0185] Furthermore, a positioning protrusion 501 is provided on the tray 503 , and a corresponding positioning protrusion 501 is provided at the location of each battery 502 . The positioning protrusion 501 is used to cooperate with the corresponding positioning groove 2041 in a limiting manner.
