Description

Technical Field

[0001] This application relates to the technical field of batteries, and particularly to a charging and discharging device. Background Art

[0002] Energy conservation and emission reduction are the keys to the sustainable development of the automotive industry. Electric vehicles have become an important part of the sustainable development of the automotive industry due to their advantages of energy conservation and environmental protection. For electric vehicles, battery technology is an important factor related to their development.

[0003] The formation of a battery is its initial activation and is an important link in the battery manufacturing process. When forming a battery, the charging and discharging device activates the positive and negative electrode materials inside the battery through a certain charging and discharging method, improving the charging and discharging performance, self-discharge, storage and other comprehensive performances of the battery.

[0004] When the charging and discharging device forms the battery, a large amount of heat will be generated. In the related art, the heat dissipation effect of the charging and discharging device is poor, which affects the formation of the battery. Utility Model Content

[0005] This application aims to solve at least one of the technical problems existing in the background art. For this reason, an object of this application is to provide a charging and discharging device to improve the heat dissipation effect of the charging and discharging device.

[0006] An embodiment of the first aspect of this application provides a charging and discharging device, which includes: a support frame; a tray connected to the support frame, the tray being configured to place a battery; a formation module connected to the support frame, the formation module being located on one side of the tray for placing the battery, the formation module including a plurality of probes configured to be electrically connected to the electrode posts of the battery; a plurality of first heat dissipation modules connected to the formation module, the plurality of first heat dissipation modules being configured to dissipate heat from the plurality of probes, and each of the plurality of probes being dissipated heat by at least one of the plurality of first heat dissipation modules.

[0007] In the technical solution of the embodiment of this application, when using the charging and discharging device provided by the embodiment of this application to form a battery, the battery is placed on the tray, and the probes of the formation module are brought into contact with the electrode posts of the battery. During the formation process, if the temperature of the probes is too high, the first heat dissipation modules can dissipate heat from the probes, and each probe can be separately dissipated heat by the first heat dissipation modules, resulting in a better heat dissipation effect for the probes and improving the heat dissipation effect of the charging and discharging device.

[0008] In some embodiments, the formation module includes at least two columns of probe modules arranged in a first direction. The probe modules extend in a second direction. Both the first direction and the second direction are parallel to the bottom surface of the tray, and the first direction intersects the second direction. The probe module includes multiple rows of probe groups arranged in the second direction. Each row of probe groups in the probe group includes a cathode probe and an anode probe. The cathode probe and the anode probe in any row of probe groups are arranged in the first direction. The multiple probes include a cathode probe and an anode probe. When forming the battery, generally multiple batteries are formed simultaneously. When multiple batteries are placed on the tray, they are generally arranged in a positive column. By setting the formation module as multiple probe modules, and the probe module includes multiple rows of probe groups, it can make the multiple probes also arranged in a positive column, so that the probe positions can correspond to the positions of the battery poles, and the probes can more conveniently contact the battery poles.

[0009] In some embodiments, the probe module includes: a connection plate connected to the support frame; two connecting rods, both extending in the second direction. The two connecting rods are arranged in the first direction. The connecting rods are connected to the side of the connection plate facing the tray. Among the multiple rows of probe groups in the probe module, one of the cathode probe and the anode probe in the probe group is connected to one of the two connecting rods, and the other of the cathode probe and the anode probe in the probe group is connected to the other of the two connecting rods. The first heat dissipation module is connected to the connecting rod. For different models of batteries, the spacing between the battery poles is not necessarily the same, and it is necessary to adjust the spacing between the cathode probe and the anode probe of the probe group according to the spacing between the battery poles. In the embodiments of the present application, for multiple rows of probe groups of the same probe module, the multiple cathode probes of the multiple rows of probe groups are connected to the same connecting rod, and the multiple anode probes of the multiple rows of probe groups are connected to the same connecting rod. Then, the spacing between the cathode probe and the anode probe of the row probe group can be adjusted by changing the position of the connecting rod, without individual adjustment, which is more convenient. At the same time, the first heat dissipation module is connected to the connecting rod. Even if the position of the probe is changed by moving the connecting rod, the relative position between the first heat dissipation module and the probe can remain unchanged, and the first heat dissipation module can still effectively dissipate heat from the probe.

[0010] In some embodiments, the probe module further includes: a slide rail connected to the side of the connection plate facing the tray. The slide rail extends in the first direction; at least two sliders slidably connected to the slide rail. The connecting rod is connected to the slider, and different connecting rods are connected to different sliders. When it is necessary to adjust the spacing of the probes according to the spacing between the battery poles, the slider can be controlled to slide on the slide rail to adjust the spacing of the probes, which is more convenient.

[0011] In some embodiments, the probe module further includes: a scale, connected to the slide rail, the scale markings of which extend in the first direction; a pointer, connected to the connecting rod, the pointer being located on one side of the scale along the second direction, and the pointer being configured to point to the scale markings of the scale. The pointer is connected to the connecting rod and can move with the connecting rod. The distance between the cathode probe and the anode probe can be more intuitively reflected by the scale marking pointed to by the pointer on the scale, and at the same time, the distance of the movement of the connecting rod can be more intuitively controlled.

[0012] In some embodiments, the first heat dissipation module includes: a mounting member, connected to the forming module; a first heat dissipation member, connected to the mounting member. The first heat dissipation member is the component for heat dissipation in the first heat dissipation module, and the mounting member is used to mount the first heat dissipation member to improve the stability of the first heat dissipation member.

[0013] In some embodiments, when the forming module includes a connecting rod, the mounting member is connected to the connecting rod. Since the probe is connected to the connecting rod, connecting the mounting member to the connecting rod can keep the relative positions of the first heat dissipation member and the probe unchanged. Even if the connecting rod drives the probe to move, the first heat dissipation member can effectively dissipate heat from the probe.

[0014] In some embodiments, the first heat dissipation module further includes: a locking member, connecting the mounting member and the first heat dissipation member; an adjusting member, located between the mounting member and the first heat dissipation member. The locking member is used to fix the first heat dissipation member on the mounting member to ensure the stability of the first heat dissipation member during the forming process. When the position of the first heat dissipation member cannot efficiently dissipate heat from the probe, the adjusting member can adjust the relative position between the first heat dissipation member and the probe so that the first heat dissipation member can efficiently dissipate heat from the probe.

[0015] In some embodiments, the first heat dissipation member includes a cooling fan, the air outlet of the cooling fan being opposite to the corresponding probe. The first heat dissipation module further includes: a wind guide plate, connected to the mounting member, the wind guide plate forming an air outlet channel between the cooling fan and the probe. The structure of the cooling fan is simple, and by setting the wind guide plate to form an air outlet channel between the cooling fan and the probe, the cooling fan can more effectively dissipate heat from the probe.

[0016] In certain embodiments, the formation module is movably connected to the support frame, and the moving direction of the formation module is a third direction, and the third direction intersects with the bottom surface of the tray. When the battery is placed on the tray, the formation module can be moved along the third direction so that the distance between the formation module and the tray increases, and the formation module avoids the battery to avoid the formation module from affecting the placement of the battery; after the battery is placed, the formation module is moved along the third direction so that the formation module is close to the battery, and the probe can be electrically connected to the pole of the battery. In addition, when the height of the battery changes, the formation module can be controlled to move along the third direction, and the formation module can be electrically connected to batteries of different heights, and the charge and discharge device can be adapted to batteries that do not pass through the height, and the scope of application is wider.

[0017] In some embodiments, the support frame includes: a bottom plate, the tray is connected to the bottom plate; a telescopic rod extending along a third direction, one end of the telescopic rod is connected to the bottom plate, and the other end of the telescopic rod is connected to the formation module; a driving member connected to the telescopic rod, and the driving member is configured to drive the telescopic rod to extend and retract. The driving member drives the telescopic rod to extend and retract, thereby controlling the movement of the formation module along the third direction. This structure is relatively simple to control the movement of the formation module, and simplifies the structure of the entire charging and discharging device.

[0018] In some embodiments, the charging and discharging device further comprises: a second heat dissipation module connected to the support frame, and the second heat dissipation module is configured to dissipate heat from the formation module and the battery. Providing the second heat dissipation module to dissipate heat from the formation module and the battery can further improve the heat dissipation effect of the charging and discharging device.

[0019] In some embodiments, the bottom surface of the tray is hollowed out, and the second heat dissipation module includes: a second heat dissipation member, which is located on a side of the tray away from the formation module, and the second heat dissipation member includes a heat dissipation fan. The second heat dissipation member can accelerate the circulation of air in the charging and discharging device, thereby achieving heat dissipation of the formation module. The second heat dissipation member blows air toward the upper part of the tray along the third direction. Since the bottom surface of the tray is hollowed out, the second heat dissipation member can blow air toward the batteries in the tray to achieve heat dissipation of the batteries.

[0020] In some embodiments, the side of the tray is hollowed out, and the second heat dissipation module further includes: a third heat dissipation element, which is located on opposite sides of the tray along the first direction, the first direction is parallel to the bottom surface of the tray, and the third heat dissipation element includes a heat dissipation fan; wherein the first heat dissipation module includes a heat dissipation fan, and the first heat dissipation module is located on one side of the probe for heat dissipation thereof along the first direction, and along the first direction, the first heat dissipation module and the third heat dissipation element close to it have the same air outlet direction. The third heat dissipation element blows air toward the middle of the tray along the first direction, and the first heat dissipation module blows air toward the middle of the tray along the first direction, and the blowing directions of the two are consistent, which can improve the heat dissipation efficiency. The second heat dissipation element blows air upward along the third direction, which can discharge the hot air in the entire charging and discharging device from the upper part, forming a circulation channel, so that the hot air can be discharged in time, which can also improve the heat dissipation efficiency.

[0021] In some embodiments, each of the multiple first heat dissipation modules dissipates heat from one of the multiple probes, and each of the multiple probes is dissipated heat by one of the multiple first heat dissipation modules. For the probe and the first heat dissipation module, each probe can be dissipated heat individually. If the temperature of one or several probes increases, the first heat dissipation module can cool the probes with increased temperature to achieve individual temperature control, with better heat dissipation effect. At the same time, setting too many first heat dissipation modules will not affect the volume of the charging and discharging device, and the volume of the charging and discharging device will not be increased while improving the heat dissipation effect.

[0022] In some embodiments, the probe includes: a current rod extending along a third direction, the current rod being connected to the support frame, and the third direction intersecting the bottom surface of the tray; a plurality of heat dissipation fins arranged along the third direction, and the plurality of heat dissipation fins are all sleeved on the current rod. Heat dissipation fins are provided to dissipate heat from the current rod. The surface area of the heat dissipation fins is large, which can improve the heat dissipation effect.

[0023] In some embodiments, the orthographic projection of the heat dissipation fin on a plane perpendicular to the third direction is circular; wherein, the first heat dissipation module includes a heat dissipation fan, and the air outlet direction of the first heat dissipation module forms an angle less than 90° with the surface of the heat dissipation fin. The air blown out by the first heat dissipation module blows towards the heat dissipation fin, and the air blows from one side around the side of the heat dissipation fin to the other side. In the related art, the air cannot reach some areas on the other side of the heat dissipation fin, and some areas of the heat dissipation fin cannot achieve effective heat dissipation. In the embodiments of the present application, since the heat dissipation fin is a circular fin, an eddy current effect will be formed in some areas on the other side of the heat dissipation fin, so that the air can reach some areas on the other side of the heat dissipation fin, thereby realizing the heat dissipation of the entire heat dissipation fin, and the heat dissipation effect is better.

[0024] In some embodiments, the probe further includes: a bracket, one end of the bracket is connected to the support frame, and the current rod passes through the bracket; an elastic member, and the current rod is connected to one end of the bracket through the elastic member. The bracket drives the current rod to move towards the battery. When the pole column contacts the current rod, the elastic member is compressed by force, thereby playing a role of buffering and protecting the current rod. After the bracket drives the current rod away from the battery, the pole column is separated from the current rod, and the elastic member drives the current rod to reset.

In order to be able to understand the technical means of the present application more clearly, it can be implemented according to the content of the specification. And in order to make the above and other purposes, features and advantages of the present application more obvious and understandable, the specific embodiments of the present application are specifically described below.

[0043] Currently, from the perspective of the development of the market situation, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely used in electric transportation such as electric bicycles, electric motorcycles, and electric vehicles, as well as in multiple fields such as military equipment and aerospace. With the continuous expansion of the application fields of power batteries, the market demand is also continuously increasing.

[0044] After the battery is manufactured, it needs to be formed. Forming refers to the first charging of the battery, which can activate the active materials inside the battery. Battery forming is generally completed through a charge and discharge device. The charge and discharge device includes a probe. When the battery is formed, the probe is electrically connected to the battery terminal post, and current flows through the probe and the terminal post, causing the probe to generate more heat. In the related art, the heat dissipation effect of the charge and discharge device is poor, resulting in too high a temperature inside the battery forming device, which affects the forming of the battery.

[0045] The embodiments of the present application provide a charge and discharge device. The charge and discharge device includes a support frame, a tray, a forming module, and a plurality of first heat dissipation modules. The tray and the forming module are both connected to the support frame. The tray is configured to place the battery, and the forming module is located on the side of the tray for placing the battery. The forming module includes a plurality of probes, and the plurality of probes are configured to be electrically connected to the battery terminal posts. The first heat dissipation modules are connected to the forming module, and the plurality of first heat dissipation modules are configured to dissipate heat from the plurality of probes. Each of the plurality of probes is dissipated heat by at least one of the plurality of first heat dissipation modules. When using the charge and discharge device provided by the embodiments of the present application to form the battery, the battery is placed on the tray, and the probes of the forming module are brought into contact with the battery terminal posts. During the forming process, if the temperature of the probe is too high, the probe can be dissipated heat by the first heat dissipation module, and each probe can be dissipated heat separately by the first heat dissipation module, so the heat dissipation effect of the probe is better, and the heat dissipation effect of the charge and discharge device is improved.

[0046] The battery formed by the charge and discharge device disclosed in the embodiments of the present application can be used in, but not limited to, electrical devices such as vehicles, ships, or aircraft.

[0047] An embodiment of the present application provides a charging and discharging device. Figure 1 It is a front view of the charging and discharging device according to some embodiments of the present application. Refer to Figure 1 , the charging and discharging device includes a support frame 10, a tray 20, a formation module 30, and a plurality of first heat dissipation modules 40. The tray 20 and the formation module 30 are both connected to the support frame 10. The tray 20 is configured to place batteries. The formation module 30 is located on one side of the tray 20 for placing batteries. The formation module 30 includes a plurality of probes 321, and the plurality of probes 321 are configured to be electrically connected to the electrode posts of the batteries. The first heat dissipation module 40 is connected to the formation module 30, and the plurality of first heat dissipation modules 40 are configured to dissipate heat from the plurality of probes 321, and each of the plurality of probes 321 is dissipated heat by at least one of the plurality of first heat dissipation modules 40.

[0048] The support frame 10 is a structure that plays a supporting role and can provide support and installation for the tray 20 and the formation module 30. The support frame 10 can be various forms of structures, such as a bracket structure, a frame structure, a guide rail structure, etc., but not limited thereto.

[0049] The tray 20 is used to support the batteries to improve the stability of the batteries during formation. The tray 20 can be various structural forms capable of supporting the batteries, such as a frame structure, a plate-like structure, a disc-like structure, etc., but not limited thereto.

[0050] The formation module 30 refers to a component including those for making electrical contact with the batteries. The formation module 30 is located on one side of the tray 20 for placing batteries so that the probes 321 of the formation module 30 can be electrically connected to the electrode posts of the batteries, thereby facilitating the charging and discharging device to perform formation on the batteries.

[0051] The first heat dissipation module 40 is used to dissipate heat from the probes 321 to reduce the temperature of the probes 321.

[0052] In the embodiment of the present application, any one of the probes 321 can be dissipated heat by one first heat dissipation module 40 or can be dissipated heat by a plurality of first heat dissipation modules 40.

[0053] In some embodiments of the present application, the first heat dissipation module 40 may include a cooling fan. The cooling fan accelerates the air flow, and the heat of the probes 321 is carried away during the air flow process to reduce the temperature of the probes 321.

[0054] In some other embodiments of the present application, the first heat dissipation module 40 may include a heat dissipation plate. The heat dissipation plate is in contact with the probes 321, and the heat dissipation plate has a heat dissipation channel. A heat dissipation medium is conveyed into the heat dissipation channel, and the heat dissipation medium exchanges heat with the probes 321 through the heat dissipation plate to reduce the temperature of the probes 321.

[0055] In some other embodiments of the present application, the first heat dissipation module 40 may include an air conditioner, which reduces the temperature of the environment where the probe 321 is located and thus reduces the temperature of the probe 321.

[0056] When using the charging and discharging device provided by the embodiments of the present application to form a battery, the battery is placed on the tray 20, and the probe 321 of the forming module 30 is brought into contact with the electrode post of the battery. During the forming process, if the temperature of the probe 321 is too high, the first heat dissipation module 40 can dissipate heat from the probe 321, and each probe 321 can be individually cooled by the first heat dissipation module 40, resulting in a better heat dissipation effect for the probe 321 and improving the heat dissipation effect of the charging and discharging device.

[0057] Exemplarily, the charging and discharging device may be a battery forming device.

[0058] According to some embodiments of the present application, referring to Figure 1 , the forming module 30 includes at least two rows of probe modules 31 arranged along the first direction X. Figure 2 It is a partial structural schematic diagram of the charging and discharging device according to some embodiments of the present application. Combining Figure 1 and Figure 2 , the probe module 31 extends along the second direction Y. Both the first direction X and the second direction Y are parallel to the bottom surface of the tray 20, and the first direction X intersects the second direction Y. The probe module 31 includes multiple rows of probe groups 32 arranged along the second direction Y. Each row of probe groups 32 in the probe group 32 includes a cathode probe and an anode probe. The cathode probe and the anode probe in any row of probe groups 32 are arranged along the first direction X. The multiple probes 321 include a cathode probe and an anode probe.

[0059] The probe module 31 is an execution component of the forming module 30 for making electrical contact with the battery and includes at least one probe for making electrical contact with the battery. The number of probe modules 31 can be two or more. Figure 1 The case of three probe modules 31 arranged in parallel is exemplarily shown in

[0060] The probe module 31 extends along the second direction Y, that is, the length direction of the probe module 31 is parallel to the second direction Y. The included angle between the first direction X and the second direction Y is between 80° and 90°.

[0061] In the embodiments of the present application, each row of probe groups 32 includes a cathode probe and an anode probe. The cathode probe is used for electrically connecting to the positive electrode post of the battery, and the anode probe is used for electrically connecting to the negative electrode post of the battery. Both the cathode probe and the anode probe belong to the probe 321.

[0062] The bottom surface of the tray 20 is the side of the tray 20 for placing the battery. When placing the battery in the tray 20, the positive and negative electrode posts of the battery are also arranged along the first direction X.

[0063] In an embodiment of the present application, the formation module 30 further includes a formation power supply 33. The formation power supply 33 is electrically connected to the probe module 31. The formation power supply 33 is a component capable of delivering or converting voltage to the probe module 31, so that the probe module 31 can be in electrical contact with the battery to perform formation on the battery.

[0064] The formation power supply 33 can be electrically connected to the probe 321 of the probe module 31 in various ways. For example, it can be electrically connected to the probe 321 of the probe module 31 through an electrical connection member (such as a wire, cable, conductive sheet, circuit board, etc.), or directly electrically connected to the probe 321 of the probe module 31.

[0065] Exemplarily, the formation power supply 33 can be arranged on the upper side of the probe module 31 along the third direction Z, and the third direction Z is the height direction of the charge and discharge device.

[0066] In some embodiments of the present application, the first direction X, the second direction Y, and the third direction Z can be perpendicular to each other pairwise. In this way, the overall shape of the charge and discharge device is closer to a cuboid, and the space occupied by the charge and discharge device is smaller.

[0067] When performing formation on the battery, generally multiple batteries are formed simultaneously. When multiple batteries are placed on the tray 20, they are generally arranged in a positive column. By setting the formation module 30 as multiple probe modules 31, and the probe module 31 includes multiple rows of probe groups 32, it can be ensured that multiple probes 321 are also arranged in a positive column. In this way, the positions of the probes 321 can correspond to the positions of the battery poles, and the probes 321 can more conveniently contact the battery poles.

[0068] In an embodiment of the present application, each probe module 31 is electrically connected to a different formation power supply 33. In this way, each probe module 31 can be independently controlled, and each probe module 31 can perform formation on one column of batteries. In the case where one probe module 31 fails, it will not affect other probe modules 31.

[0069] According to some embodiments of the present application, in combination with Figure 1 and Figure 2, the probe module 31 includes a connecting plate 311 and two connecting rods 312. The connecting plate 311 is connected to the support frame 10. The two connecting rods 312 both extend along the second direction Y, and the two connecting rods 312 are arranged along the first direction X. The connecting rods 312 are connected to the side of the connecting plate 311 facing the tray 20. Among them, for multiple rows of probe groups 32 in the probe module 31, one of the cathode probe and the anode probe in the probe group 32 is connected to one of the two connecting rods 312, and the other of the cathode probe and the anode probe in the probe group 32 is connected to the other of the two connecting rods 312. The first heat dissipation module 40 is connected to the connecting rod 312.

[0070] In an embodiment of the present application, the connecting plates 311 of multiple probe modules 31 can be shared, or each probe module 31 separately includes a connecting plate 311.

[0071] In an embodiment of the present application, the connecting plate 311 is connected to the support frame 10. The connecting plate 311 can be connected to the support frame 10 through various installation methods. For example, it can be connected by fasteners (such as screws, locking parts, pins, rivets, clamps, binding ropes, etc., but not limited thereto), snap connection, plug connection, welding, etc., but not limited thereto. Similarly, the connecting rod 312 and the connecting plate 311 can also be connected by any of the above installation methods.

The formation power supply 33 and the connecting plate 311 can also be connected by any of the above installation methods.

[0073] For batteries of different models, the distances between the battery poles are not necessarily the same, and it is necessary to adjust the distances between the cathode probe and the anode probe of the probe group 32 according to the distances between the battery poles. In an embodiment of the present application, for multiple rows of probe groups 32 of the same probe module 31, the multiple cathode probes of the multiple rows of probe groups 32 are connected to the same connecting rod 312, and the multiple anode probes of the multiple rows of probe groups 32 are connected to the same connecting rod 312. Then, the distances between the cathode probe and the anode probe of the row probe group 32 can be adjusted by changing the position of the connecting rod 312, without the need for individual adjustment, which is more convenient. At the same time, the first heat dissipation module 40 is connected to the connecting rod 312. Even if the connecting rod 312 is moved to change the position of the probe 321, the relative position between the first heat dissipation module 40 and the probe 321 can remain unchanged, and the first heat dissipation module 40 can still effectively dissipate heat from the probe 321.

[0074] In an embodiment of the present application, the multiple probes 321 connected to the same connecting rod 312 are arranged along the second direction Y.

[0075] According to some embodiments of the present application, in combination withFigure 1 and Figure 2 Figure 2 , the probe module 31 further includes a slide rail 313 and at least two sliders 314.

The slider 314 is slidably connected to the slide rail 313, and the connecting rod 312 is connected to the slider 314. Different connecting rods 312 are connected to different sliders 314.

[0076] In the embodiment of the present application, the slide rail 313 extends along the first direction X, that is, the moving direction of the connecting rod 312 is the first direction X.

[0077] In the embodiment of the present application, different connecting rods 312 are connected to different sliders 314, so that each connecting rod 312 can be individually controlled to move without mutual influence.

[0078] In some embodiments of the present application, the probe module 31 may include one slide rail 313 and two sliders 314. The slide rail 313 is connected to the middle of the connecting plate 311, and the middle of the connecting rod 312 is connected to the slider 314.

[0079] In other embodiments of the present application, the probe module 31 may include two slide rails 313 and four sliders 314. The two slide rails 313 are arranged along the second direction Y. The two slide rails 313 are connected to both ends of the connecting plate 311 along the second direction Y. Each of the two slide rails 313 is connected to two sliders 314. Both ends of the connecting rod 312 are respectively connected to two sliders 314, and both ends of the connecting rod 312 are connected, making the connecting rod 312 more stable.

[0080] In some embodiments of the present application, the slide rail 313 may be directly connected to the connecting plate 311.

[0081] In other embodiments of the present application, the probe module 31 may further include two connecting side plates 317. The two connecting side plates 317 are arranged along the first direction X, and both of the two connecting side plates 317 are connected to the connecting plate 311. Both ends of the slide rail 313 are respectively connected to the two connecting side plates 317.

[0082] In the embodiment of the present application, two connecting rods 312 are connected to the same slide rail 313 through sliders 314. In other implementation manners, two connecting rods 312 may be connected to different slide rails 313.

[0083] In the embodiment of the present application, when it is necessary to adjust the distance between the probes 321 according to the distance between the battery poles, the sliders 314 can be controlled to slide on the slide rail 313 to adjust the distance between the probes 321, which is more convenient.

[0084] According to some embodiments of the present application, Figure 3The left view of a partial structure of a charge-discharge device according to some embodiments of the present application. Figure 4 The front view of a partial structure of a charge-discharge device according to other embodiments of the present application. Combining Figures 1 to 4 , the probe module 31 further includes a scale 315 and a pointer 316. The scale 315 is connected to the connecting rod 312, and the scale of the scale 315 extends along the first direction X. The pointer 316 is connected to the connecting rod 312, the pointer 316 is located on one side of the scale 315 along the second direction Y, and the pointer 316 is configured to point to the scale of the scale 315.

[0085] In an embodiment of the present application, the graduation value of the scale 315 can be 1 mm.

[0086] In an embodiment of the present application, the probes 321 and the pointer 316 connected to the same connecting rod 312 are arranged with their centers along the second direction Y. For the same row of probe groups 32, the distance between the cathode probe and the anode probe is equal to the distance between the corresponding two pointers 316.

[0087] In some embodiments of the present application, the middle part of the scale 315 is the origin of the scale, the scale increases sequentially on both sides along the first direction X, and the sum of the scales pointed by the two pointers 316 is the distance between the cathode probe and the anode probe.

[0088] In other embodiments of the present application, the origin of the scale 315 is located at one end of the scale 315. Along the first direction X, the scale of the scale 315 increases sequentially to the other side, and the absolute value of the difference between the scales pointed by the two pointers 316 is the distance between the cathode probe and the anode probe.

[0089] In an embodiment of the present application, the pointer 316 is connected to the connecting rod 312, and the pointer 316 can move with the connecting rod 312. Through the scale pointed by the pointer 316 on the scale 315, the distance between the cathode probe and the anode probe can be more intuitively reflected, and at the same time, the distance of the movement of the connecting rod 312 can also be more intuitively controlled.

[0090] According to some embodiments of the present application, combining Figures 1 to 4 , the first heat dissipation module 40 includes a mounting member 41 and a first heat dissipation member 42. The mounting member 41 is connected to the forming module 30, and the first heat dissipation member 42 is connected to the mounting member 41.

[0091] Exemplarily, the mounting member 41 is a structural member for providing support and installation for the first heat dissipation member 42, and can be a structure of various shapes, such as a strip structure, a plate structure, a block structure, etc., but not limited thereto. The first heat dissipation member 42 is a structural member for heat dissipation.

[0092] In an embodiment of the present application, the first heat dissipation member 42 is a heat dissipation component in the first heat dissipation module 40, and the mounting member 41 is used to mount the first heat dissipation member 42 to improve the stability of the first heat dissipation member 42.

[0093] According to some embodiments of the present application, when the forming module 30 includes the connecting rod 312, the mounting member 41 is connected to the connecting rod 312.

[0094] Exemplarily, the mounting member 41 and the connecting rod 312 can be connected by welding, or the mounting member 41 and the connecting rod 312 can be connected by bolts.

[0095] In an embodiment of the present application, since the probe 321 is connected to the connecting rod 312, connecting the mounting member 41 and the connecting rod 312 can keep the relative position between the first heat dissipation member 42 and the probe 321 unchanged. Even if the connecting rod 312 drives the probe 321 to move, the first heat dissipation member 42 can effectively dissipate heat from the probe 321.

[0096] In an embodiment of the present application, a plurality of first heat dissipation members 42 can share one mounting member 41.

[0097] According to some embodiments of the present application, referring to Figure 4 , the first heat dissipation module 40 further includes a locking member 43 and an adjusting member 44. The locking member 43 connects the mounting member 41 and the first heat dissipation member 42; the adjusting member 44 is located between the mounting member 41 and the first heat dissipation member 42.

[0098] In an embodiment of the present application, the locking member 43 is a structural member that plays a fastening or locking role. For example, it can be various types of fasteners (such as screws, bolts, pins, etc., but not limited thereto), or it can be a pressing member, but not limited thereto.

[0099] Exemplarily, the locking member 43 includes a bolt and a nut. Both the mounting member 41 and the first heat dissipation member 42 are provided with mounting through holes. The bolt passes through the mounting through holes on the mounting member 41 and the first heat dissipation member 42 in sequence and is threadedly connected to the nut, thereby connecting the mounting member 41 and the first heat dissipation member 42.

[0100] In an embodiment of the present application, the adjusting member 44 is a component for adjusting the relative position between the locking member 43 and the first heat dissipation member 42.

[0101] Exemplarily, the adjusting member 44 can be a gasket. By changing the thickness of the gasket, the position between the mounting member 41 and the first heat dissipation member 42 is changed, and the first heat dissipation member 42 has a certain inclination angle relative to the mounting member 41, thereby changing the relative position between the first heat dissipation member 42 and the probe 321.

[0102] In an embodiment of the present application, the locking member 43 is used to fix the first heat sink 42 on the mounting member 41 to ensure the stability of the first heat sink 42 during the formation process. When the first heat sink 42 cannot efficiently dissipate heat from the probe 321, the adjusting member 44 can adjust the relative position between the first heat sink 42 and the probe 321 so that the first heat sink 42 can efficiently dissipate heat from the probe 321.

[0103] According to some embodiments of the present application, the first heat sink 42 includes a cooling fan, and the air outlet of the cooling fan faces the corresponding probe 321. Refer to Figure 4 , the first heat dissipation module 40 further includes a wind guide plate 45. The wind guide plate 45 is connected to the mounting member 41, and the wind guide plate 45 forms an air outlet channel between the cooling fan and the probe 321.

[0104] In an embodiment of the present application, the mounting member 41 may be an L-shaped plate. One side wall of the L-shaped plate is connected to the connecting rod 312, and the other side wall of the L-shaped plate is connected to the first heat sink 42, so that the air outlet of the first heat sink 4 can face the corresponding probe 321.

[0105] Exemplarily, the first heat sink 42 may be located on the side of the other side wall of the L-shaped plate facing the probe 321; or, the first heat sink 42 may be located on the side of the other side wall of the L-shaped plate away from the probe 321, and an air outlet through hole corresponding to the air outlet of the first heat sink 42 is provided on the other side wall of the L-shaped plate, so that the air from the air outlet of the first heat sink 42 can blow towards the probe 321 through the air outlet through hole.

[0106] In an embodiment of the present application, the wind guide plate 45 may be connected to the other side wall of the L-shaped plate, and the wind guide plate 45 surrounds the air outlet of the first heat sink 42.

[0107] In an embodiment of the present application, the structure of the cooling fan is simple. At the same time, the wind guide plate 45 is provided to form an air outlet channel between the cooling fan and the probe 321, so that the cooling fan can more effectively dissipate heat from the probe 321.

[0108] According to some embodiments of the present application, the formation module 30 is movably connected to the support frame 10, and the moving direction of the formation module 30 is the third direction Z, and the third direction Z intersects with the bottom surface of the tray 20.

[0109] In the embodiment of the present application, the formation module 30 can be arranged on the support frame 10 by a variety of movable connection methods, such as sliding fit, rolling fit, etc., but not limited thereto, as long as the formation module 30 can move relative to the support frame 10 along the first direction A, that is, the formation module 30 is moved and arranged roughly along a straight line direction. Among them, the third direction Z can be any straight line direction, for example, it can be the height direction of the charge and discharge device, but not limited thereto.

[0110] In an embodiment of the present application, when placing the battery on the tray 20, the formation module 30 can be moved along the third direction Z so that the distance between the formation module 30 and the tray 20 increases, and the formation module 30 avoids the battery to prevent the formation module 30 from affecting the placement of the battery; after the battery is placed, the formation module 30 is moved along the third direction Z so that the formation module 30 is close to the battery, and the probe 321 can be electrically connected to the pole of the battery. In addition, when the height of the battery changes, the formation module 30 can be controlled to move along the third direction Z, and the formation module 30 can be electrically connected to batteries of different heights, and the charge and discharge device can be adapted to batteries that do not pass through the height, and the scope of application is wider.

[0111] According to some embodiments of the present application, see Figure 1 The support frame 10 includes a bottom plate 11, a telescopic rod 12 and a driving member 13. The tray 20 is connected to the bottom plate 11; the telescopic rod 12 extends along the third direction Z, one end of the telescopic rod 12 is connected to the bottom plate 11, and the other end of the telescopic rod 12 is connected to the formation module 30; the driving member 13 is connected to the telescopic rod 12, and the driving member 13 is configured to drive the telescopic rod 12 to extend and retract.

[0112] In the embodiment of the present application, the bottom plate 11 provides support for the telescopic rod 12 , and the driving member 13 may be disposed on the bottom plate 11 to improve the stability of the driving member 13 .

[0113] In the embodiment of the present application, the other end of the telescopic rod 12 may be connected to the connecting plate 311 of the formation module 30 .

[0114] In some embodiments of the present application, the other end of the telescopic rod 12 is directly connected to the connecting plate 311 of the formation module 30 .

[0115] In other embodiments of the present application, the other end of the telescopic rod 12 is indirectly connected to the connecting plate 311 of the formation module 30. Exemplarily, the support frame 10 further includes a lifting plate 14, which is connected to the other end of the telescopic rod 12, and the connecting plate 311 is connected to the lifting plate 14.

[0116] Exemplarily, the driving member 13 may include a cylinder; or, the driving member 13 may include a hydraulic cylinder; or, the driving member 13 may include a motor.

[0117] In an embodiment of the present application, the driving member 13 drives the telescopic rod 12 to expand and contract, thereby controlling the formation module 30 to move along the third direction Z. This structure for controlling the movement of the formation module is relatively simple, simplifying the structure of the entire charging and discharging device.

[0118] According to some embodiments of the present application, referring to Figure 1 , the charging and discharging device further includes a second heat dissipation module 50. The second heat dissipation module 50 is connected to the support frame 10 and is configured to dissipate heat from the formation module 30 and the battery.

[0119] In an embodiment of the present application, the heat dissipation method of the second heat dissipation module 50 may be the same as or different from that of the first heat dissipation module 40.

[0120] In an embodiment of the present application, setting the second heat dissipation module 50 to dissipate heat from the formation module 30 and the battery can further improve the heat dissipation effect of the charging and discharging device.

[0121] According to some embodiments of the present application, the bottom surface of the tray 20 is hollowed out. Referring to Figure 1 , the second heat dissipation module 50 includes a second heat dissipation member 51. The second heat dissipation member 51 is located on the side of the tray 20 away from the formation module 30, and the second heat dissipation member 51 includes a cooling fan.

[0122] In some embodiments of the present application, side walls may be provided around the bottom plate 11, and the tray 20 is connected to the side walls.

[0123] In some other embodiments of the present application, the support frame 10 may further include support columns 15. The support columns 15 extend along the third direction Z. One end of the support column 15 is connected to the bottom plate 11, and the other end of the support column 15 is used to support the tray 20. The support columns 15 can suspend and support the tray 20, which is beneficial to heat dissipation.

[0124] In an embodiment of the present application, the second heat dissipation member 51 can accelerate the air flow inside the charging and discharging device, thereby achieving heat dissipation of the formation module 30. The second heat dissipation member 51 blows air towards the upper part of the tray 20 along the third direction Z. Since the bottom surface of the tray 20 is hollowed out, the second heat dissipation member 51 can blow air towards the battery inside the tray 20 to achieve heat dissipation of the battery.

[0125] According to some embodiments of the present application, the side surface of the tray 20 is hollowed out. Referring to Figure 1, the second heat dissipation module 50 further includes a third heat dissipation member 52. The third heat dissipation member 52 is located on opposite sides of the tray 20 along the first direction X, and the first direction X is parallel to the bottom surface of the tray 20. The third heat dissipation member 52 includes a heat dissipation fan. Among them, the first heat dissipation module 40 includes a heat dissipation fan. The first heat dissipation module 40 is located on one side of the probe 321 to be cooled by it along the first direction X. Along the first direction X, the air outlet direction of the first heat dissipation member 42 is the same as that of the third heat dissipation member 52 closest to it.

[0126] In an embodiment of the present application, the third heat dissipation member 52 is located on opposite sides of the tray 20 along the first direction X, and the third heat dissipation member 52 blows air towards the middle of the tray 20 along the first direction X. The first heat dissipation module 40 also blows air towards the probe 321 along the first direction X.

[0127] Taking Figure 1 as an example, the first direction X is the Figure 1 left - right direction in Figure 1 , the third direction Z is the

[0128] up - down direction in

[0129] Exemplarily, Figure 1 the dotted line with an arrow in

[0130] can generally represent the flow direction of air in the charge - discharge device. Along the first direction X, if the probe 321 is located at the left - hand side position of the entire charge - discharge device, then the first heat dissipation module 40 corresponding to the probe 321 is located on the left side of the probe 321 along the first direction X; if the probe 321 is located at the right - hand side position of the entire charge - discharge device, then the first heat dissipation module 40 corresponding to the probe 321 is located on the right side of the probe 321 along the first direction X. It can be understood that the first heat dissipation module 40 is located on the outer - side - close side of its corresponding probe 321, which is convenient for repairing or disassembling the first heat dissipation module 40 on the outside.

[0131] That is, each probe 321 is cooled separately by a first heat dissipation module 40, and a first heat dissipation module 40 cools a probe 321.

[0132] It should be noted that when the first heat dissipation module 40 includes a heat dissipation fan, the first heat dissipation module 40 will inevitably blow air to other probes 321, as long as the air outlet of the first heat dissipation module 40 faces the corresponding probe 321.

[0133] In the embodiments of the present application, for the probe 321 and the first heat dissipation module 40, each probe 321 can be cooled separately, with better heat dissipation effect. At the same time, there is no need to set a large number of first heat dissipation modules 40, which will not affect the volume of the charge and discharge device, and will not increase the volume of the charge and discharge device while improving the heat dissipation effect.

[0134] In the embodiments of the present application, when the battery is formed, if the contact internal resistance is large due to inaccurate pressing of any one probe 321 with the battery terminal post, causing the temperature of one or several probes 321 to rise, the first heat dissipation module 40 can be used to accelerate the cooling of the probes 321 with increased temperature (such as increasing the wind speed), realizing independent temperature control, which is more convenient. At the same time, since it is not necessary to cool all the probes 321, the energy consumption can be reduced and the cost can be lowered.

[0135] In the embodiments of the present application, Figure 5 This is a partial structural schematic diagram of the probe in some embodiments of the present application. Refer to Figure 5 and the probe 321 includes a current rod 3211 and a plurality of heat dissipation fins 3212. The current rod 3211 extends along the third direction Z. Combining Figure 2 and Figure 5 , the third direction Z intersects with the bottom surface of the tray 20. The plurality of heat dissipation fins 3212 are arranged along the third direction Z, and the plurality of heat dissipation fins are all sleeved on the current rod 3211.

[0136] In the embodiments of the present application, the current rod 3211 is a component for passing current. The current rod 3211 is connected to the formation power supply 33, and the head of the current rod 3211 contacts the battery terminal post to realize the electrical connection between the battery and the formation power supply 33.

[0137] Exemplarily, the current rod 3211 is connected to the connecting rod 312 to ensure the stability of the current rod 3211.

[0138] The heat dissipation fin 3212 is a component for taking away the heat generated when the current rod 3211 works. When the current rod 3211 works, the current rod 3211 will generate heat, and the heat dissipation fin 3212 is used to reduce the temperature of the current rod 3211.

[0139] Exemplarily, the heat dissipation fin 3212 is located at the head of the current bar 3211. Since the main parts where heat is concentrated when the current bar 3211 is working are the head and the area near the head, the heat dissipation fin 3212 can be used to reduce the temperature of the head. The heat dissipation fin 3212 can increase the contact area with air, allowing air to carry away the heat generated when the current bar 3211 is working more quickly.

[0140] According to some embodiments of the present application, the heat dissipation fin 3212 is provided to dissipate heat from the current bar 3211. The surface area of the heat dissipation fin 3212 is relatively large, which can improve the heat dissipation effect.

[0141] In an embodiment of the present application, the orthographic projection of the heat dissipation fin 3212 on a plane perpendicular to the third direction Z is circular. Among them, the first heat dissipation module 40 includes a heat dissipation fan, and the air outlet direction of the first heat dissipation module 40 forms an angle less than 90° with the surface of the heat dissipation fin 3212.

[0142] The orthographic projection of the heat dissipation fin 3212 on a plane perpendicular to the third direction Z is circular, that is, the heat dissipation fin 3212 is a circular sheet.

[0143] In some embodiments of the present application, the air outlet direction of the first heat dissipation module 40 is parallel to the surface of the heat dissipation fin 3212.

[0144] In some embodiments of the present application, the air outlet direction of the first heat dissipation module 40 intersects but is not perpendicular to the surface of the heat dissipation fin 3212. Then, the air outlet direction of the first heat dissipation module 40 has a component parallel to the surface of the heat dissipation fin 3212.

[0145] Figure 6 This is a simplified top view of the first heat dissipation module and the heat dissipation fin in some embodiments of the present application. Refer to Figure 6 , the wind blown out by the first heat dissipation module 40 blows towards the heat dissipation fin 3212, and the wind blows from one side around the side of the heat dissipation fin 3212 to the other side. In the related art, the wind cannot reach some areas on the other side of the heat dissipation fin 3212, and some areas of the heat dissipation fin 3212 cannot achieve effective heat dissipation. In the embodiment of the present application, since the heat dissipation fin 3212 is a circular sheet, an eddy current effect will be formed in some areas on the other side of the heat dissipation fin 3212, enabling the wind to reach some areas on the other side of the heat dissipation fin 3212, thereby realizing the heat dissipation of the entire heat dissipation fin 3212 and achieving a better heat dissipation effect.

[0146] Exemplarily, Figure 6 The solid line with an arrow in [Figure reference] can generally represent the direction of the wind.

[0147] In the embodiment of the present application, refer to Figure 5, the probe 321 further includes a bracket 3213 and an elastic member 3214. One end of the bracket 3213 is connected to the support frame 10, the current rod 3211 passes through the bracket 3213, and the current rod 3211 is connected to one end of the bracket 3213 through the elastic member 3214.

[0148] In some embodiments, the elastic member 3214 can be a spring, and one end of the bracket 3213 can be connected to the support frame 10 through a connecting rod 312 to improve the stability of the bracket 3213, that is, to improve the stability of the current rod 3211.

[0149] In some embodiments of the present application, the end of the current rod 3211 for contacting the battery pole is a rough surface, which increases the friction between the current rod 3211 and the battery pole, and avoids the sliding of the current rod 3211 or the battery pole, resulting in poor contact between the current rod 3211 and the battery pole.

[0150] In the embodiments of the present application, the bracket 3213 drives the current rod 3211 to move towards the battery. When the pole contacts the current rod 3211, the elastic member 3214 is compressed by force, thereby playing a role of buffering and protecting the current rod 3211. After the bracket 3213 drives the current rod 3211 away from the battery, the pole separates from the current rod 3211, and the elastic member 3214 drives the current rod 3211 to reset.

[0151] In the embodiments of the present application, the material of the heat dissipation fins 3212 includes red copper, beryllium copper, silver tungsten, tungsten gold, etc., to improve the heat dissipation coefficient of the heat dissipation fins 3212.

[0152] The embodiments of the present application provide a charge and discharge device, which includes a support frame 10, a tray 20, a forming module 30, a plurality of first heat dissipation modules 40 and a second heat dissipation module 50. The tray 20, the forming module 30 and the second heat dissipation module 50 are all connected to the support frame 10. The tray 20 is configured to place the battery. The forming module 30 is located on one side of the tray 20 for placing the battery. The forming module 30 includes a plurality of probes 321, and the plurality of probes 321 are configured to be electrically connected to the poles of the battery. The first heat dissipation module 40 is connected to the forming module 30, and the plurality of first heat dissipation modules 40 are configured to dissipate heat from the plurality of probes 321. Each of the plurality of probes 321 is dissipated by one of the plurality of first heat dissipation modules 40, and each of the plurality of first heat dissipation modules 40 dissipates heat from one of the plurality of probes 321.

[0153] The support frame 10 includes a bottom plate 11, a telescopic rod 12, a driving member 13, a lifting plate 14, and a support column 15. The telescopic rod 12 and the support column 15 both extend along the third direction Z, and the third direction Z intersects with the bottom surface of the tray 20. One end of the telescopic rod 12 is connected to the bottom plate 11, the other end of the telescopic rod 12 is connected to the lifting plate 14, and the chemical conversion module 30 is connected to the lifting plate 14; the driving member 13 is connected to the telescopic rod 12, and the driving member 13 is configured to drive the telescopic rod 12 to expand and contract. One end of the support column 15 is connected to the bottom plate 11, and the other end of the support column 15 is used to support the tray 20.

[0154] The probe module 31 extends along the second direction Y. The first direction X and the second direction Y are both parallel to the bottom surface of the tray 20, and the first direction X intersects with the second direction Y.
