Technical Field

[0002] The present application relates to the technical field of power batteries, and in particular to a heating device and a battery processing system. Background Art

[0003] Energy conservation and emission reduction are key to the sustainable development of the automotive industry. Electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of the sustainable development of the automotive industry. For electric vehicles, battery technology is a key factor in their development.

[0004] During the battery production process, the battery module needs to be heated to improve its reliability. During this heating and pressurizing process, the battery module is usually secured by a positioning structure. During the transportation of the battery module to the heating device, the equipment that transfers the battery module is affected by the positioning structure. The limited space for battery transfer can easily cause collisions with the positioning structure, resulting in damage to the battery module or the transfer equipment.

[0005] Summary of the Invention

[0006] In view of the above problems, the present application provides a heating device and a battery processing system that can reduce the impact on battery module transfer equipment.

[0007] In a first aspect, an embodiment of the present application provides a heating device for heating a battery module, the heating device comprising:

[0008] The bottom plate has a first position and a second position that are staggered, and the second position is used for placing the battery module;

[0009] a bracket movably connected to the base plate and configured to move between a first position and a second position;

[0010] Positioning assembly, used to press and hold the electrode terminals of the battery module;

[0011] The positioning assembly is movably arranged on the bracket. When the bracket moves to the first position, the positioning assembly at least partially avoids the upper area of ​​the second position; when the bracket moves to the second position, the positioning assembly is above the second position and can move toward the direction close to the base plate.

[0012] In the technical solution of this embodiment, the positioning assembly can be staggered with the second position when the bracket is in the first position. At this time, the positioning assembly and the bracket can be on one side of the second position, while the upper part of the second position and the other side of the second position are left empty, so as to reduce the interference of the bracket and the positioning assembly on the battery module transfer process, and reduce the situation where the battery module collides with the positioning assembly or the bracket during the transfer process; the positioning assembly can be above the battery module when the bracket is in the second position, and the positioning assembly can move toward the base plate at this time to press and fix the battery module on the base plate.

[0013] In some embodiments, when the bracket moves to the first position, the orthographic projection of the positioning component on the base plate is staggered with the second position.

[0014] In the technical solution of this embodiment, the projection of the positioning component on the bottom plate in the first position is staggered with that in the second position, so that the positioning component can be completely staggered with the second position when in the first position, and the positioning component will not block the space directly above the second position, thereby further reducing interference with the battery module transfer process.

[0015] In some embodiments, the bracket is movably arranged along the width direction of the bottom plate, and the first position and the second position are arranged in sequence along the width direction of the bottom plate.

[0016] In the technical solution of this embodiment, the bracket is moved along the width direction of the base plate to reduce the distance the bracket moves, so that the positioning component can move to the first position more quickly with the bracket, reducing interference with the battery module transfer process and improving production efficiency.

[0017] In some embodiments, a first guide structure and a first driving member are provided on the bottom plate, the bracket is slidably connected to the first guide structure, and the first driving member is used to drive the bracket to slide along the first guide structure.

[0018] The technical solution of this embodiment provides some specific structures in which the bracket is movably arranged on the bottom plate. The first driving member can drive the bracket to move along the first guide structure to drive the positioning assembly to move synchronously.

[0019] In some embodiments, the positioning assembly includes a first pressing structure and a second pressing structure, the first pressing structure and the second pressing structure being used to press the electrode terminals corresponding to the two poles of the battery module respectively;

[0024] In the technical solution of this embodiment, the first pressing structure includes a plurality of first pressing members, and each first pressing member is capable of pressing two or more electrode terminals, that is, the first pressing member has a certain length in the arrangement direction of the electrode terminals. When the spacing between the electrode terminals on battery modules of different specifications is different, the arrangement does not need to be adjusted and can still press the electrode terminals; by having more than two first pressing members, the length of each first pressing member in the arrangement direction of the electrode terminals is not too long, thereby reducing the occurrence of uneven pressing by the first pressing members.

[0025] In some embodiments, a first elastic member is provided between the first pressing member and the first base.

[0026] In the technical solution of this embodiment, the first elastic member is arranged between the first pressing member and the first base.

[0029] Similar to the first pressing structure, in the technical solution of this embodiment, each second pressing member is capable of pressing two or more electrode terminals, that is, the second pressing member has a certain length in the arrangement direction of the electrode terminals. When the spacing between the electrode terminals on battery modules of different specifications is different, this setting does not need to be adjusted and can still press the electrode terminals; having more than two second pressing members can make the length of each second pressing member in the arrangement direction of the electrode terminals not too long, thereby reducing the occurrence of uneven pressing of the second pressing members.

[0099] Currently, market developments indicate that power batteries are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace. As power battery applications continue to expand, market demand is also growing.

[0100] During the production and processing of batteries, the electrode terminals in the battery module are its key structure, which is used to realize the input and output of current. If the electrode terminals are loose or have poor contact, it may cause the internal resistance of the battery cell to increase, the discharge efficiency to decrease, and even safety problems may occur.

[0101] In order to make the connections between the various components in the battery module tighter and to improve the charging and discharging efficiency of the battery module, the battery module is currently heated and pressurized after the battery module is assembled. This is to improve the tightness of the connection between the various components of the battery module, reduce the connection gap, and at the same time improve the stability of the battery module, thereby improving the charging and discharging efficiency of the battery module, and discharge water vapor, condensation, etc. in the battery module, thereby improving the safety performance of the battery module.

[0102] During the battery production and processing process, heating equipment is often used to heat and pressurize the battery modules. During the heating and pressurization process, the electrode terminals of the battery modules need to be pressed to reduce the occurrence of poor contact and increase the stability of the battery.

[0103] Because the multiple battery cells in the battery module are mainly arranged in sequence along the short sides of the battery cells, and the electrode terminals in the battery module are usually in two or four rows, there are two pressing structures for the electrode terminals in the heating device and they are located on opposite sides of the battery module. The two pressing structures can move away from each other and make space for the battery transferring device (such as a robot) to transfer the battery module.

[0104] In this type of heating device, the two holding structures occupy space on either side of the battery module. When transferring a battery cell, the transfer device often raises the battery cell above the highest point of the holding structures to avoid the holding structures on both sides and reduce collision damage to the battery cell. This results in the heating device requiring a larger amount of space above the transfer device to accommodate the transfer device and reduce collision damage to the battery module.

[0105] Based on the above considerations, in order to reduce the interference of the heating equipment on the battery loading and unloading process and reduce the space occupied by the heating device, some embodiments of the present application provide a heating device, in which a second position for placing the battery module is set on the base plate, and a bracket that can move relative to the base plate is set, and a positioning assembly for pressing the electrode terminal is set on the bracket. The bracket can move to one side of the second position, driving the positioning assembly to move to one side of the second position.

[0106] In such a heating device, the positioning assembly can move with the bracket to one side of the second position and intersect with the second position. At this time, the positioning assembly can make room for the space above the second position and away from the side of the bracket. The battery transfer device can move on the side opposite to the bracket in the second position without making the battery module pass over the bracket and the positioning assembly, thereby reducing the upper space requirements of the heating device, reducing the space occupied by the heating device, and reducing the collision damage to the battery module during the transfer process.

[0107] In order to illustrate the technical solution of the present application, the following description is given with reference to specific drawings and embodiments.

[0108] Refer to FIG. 1 , which is a three-dimensional schematic diagram of a battery module 200 provided in some embodiments of the present application.

[0109] In FIG. 1 , the direction of the X-axis is the length direction of the battery module 200 , the direction of the Y-axis is the width direction of the battery module 200 , and the direction of the Z-axis is the height direction of the battery module 200 .

[0110] The battery module 200 includes multiple battery cells 60, which can be connected in series, in parallel, or in mixed connection. Mixed connection means that the multiple battery cells 60 are connected in series and in parallel. The multiple battery cells 60 can be arranged in sequence along the length direction X of the battery module 200, and only one battery cell 60 can be set in the width direction Y of the battery module 200 to form a single-row battery module 200; or two battery cells 60 can be set to form a double-row battery module 200.

[0111] Each battery cell 60 may be a secondary battery cell or a primary battery cell; may also be a lithium-sulfur battery cell, a sodium-ion battery cell, or a magnesium-ion battery cell, but is not limited thereto. The battery cell 60 may be cylindrical, flat, rectangular, or in other shapes.

[0112] The battery cell 60 is the smallest unit of the battery and includes an electrode terminal 61 and other functional components. The electrode terminal 61 can be used to electrically connect to the electrode assembly inside the battery cell 60 to output or input electrical energy to the battery cell 60.

[0113] In a first aspect, some embodiments of the present application provide a heating device 100 for heating a battery module 200. Referring to Figures 2 to 5, the direction of the X-axis in Figure 2 is the length direction of the heating device 100, the direction of the Y-axis is the width direction of the heating device 100, and the direction of the Z-axis is the height direction of the heating device 100.

[0114] The heating device 100 includes a base plate 10, a bracket 30 and a positioning assembly 40; wherein the base plate 10 has a first position and a second position that are staggered, and the second position is used to place the battery module 200; the bracket 30 is movably connected to the base plate 10 and is used to move between the first position and the second position; the positioning assembly 40 is used to press the electrode terminal 61 of the battery module 200, and the positioning assembly 40 is movably provided on the bracket 30. When the bracket 30 moves to the first position, the positioning assembly 40 at least partially avoids the upper area of ​​the second position. When the bracket 30 moves to the second position, the positioning assembly 40 is above the second position and can move toward the direction close to the base plate 10.

[0115] The base plate 10 refers to a structure in the heating device 100 that is mainly used to provide a fixed foundation for other structures. At the same time, the base plate 10 can also be placed on the bottom surface, workbench, etc. to provide support for other structures of the heating device 100; the shape of the base plate 10 can be square, round or other shapes; the material of the base plate 10 can include metal, plastic or other materials.

[0116] The first position and the second position both refer to positions defined on the base plate 10 . Blocking members may be provided on the base plate 10 to enclose the first position and the second position, or the first position and the second position may simply be positions set on the base plate 10 .

[0117] The second position is used for placing the battery module 200 , that is, the battery module that needs to be heated can also be placed in the second position, and the heated battery module can also be taken out from the second position.

[0118] The first position and the second position may be arranged sequentially in the length direction X of the heating device 100 , or in the width direction Y of the heating device 100 , or in other directions.

[0119] The bracket 30 refers to a structure in the heating device 100 that is mainly used to provide a fixed foundation for the positioning component 40. The bracket 30 can be a frame structure, a columnar structure or other structure; the material of the bracket 30 can include metal, plastic or other materials.

[0120] The bracket 30 can move relative to the base plate 10. For example, running wheels can be provided on the bracket 30 to enable the bracket 30 to move relative to the base plate 10 through the running wheels; for another example, a slide groove can be provided on the base plate 10, and one end of the bracket 30 can be slidably connected to the slide groove; for another example, a guide shaft passing through the bracket 30 can be provided on the base plate 10 to enable the bracket 30 to move along the guide shaft; it can be understood that the bracket 30 can also be movably connected to the base plate 10 in other ways, and is not limited to the above-mentioned ways.

[0121] The bracket 30 can move relative to the base plate 10 between a first position and a second position. Since the second position is used to place the battery module 200, when the bracket 30 moves to the second position, the bracket 30 is next to the battery module 200. It can be understood that in addition to the first position and the second position, the bracket 30 can also move to other positions.

[0122] The positioning component 40 refers to a structure in the heating device 100 that is mainly used to press the electrode terminal 61 of the battery module 200. When the battery module 200 is placed in the second position, the positioning component 40 can press the electrode terminal 61; the positioning component 40 may include a pressure column that can press the electrode terminal 61 one-to-one, and may also include a pressure plate that can press multiple electrode terminals 61. The positioning component 40 may also include other structures.

[0123] The positioning assembly 40 is provided on the bracket 30 and can move with the movement of the bracket 30; when the bracket 30 is in the first position, the positioning assembly 40 is also in the first position. At this time, the positioning assembly 40 at least partially avoids the upper area of ​​the second position, and the positioning assembly 40 is at least partially staggered with the second position, and can expose part of the space above the second position, or can completely expose the space above the second position, so as to facilitate the transfer of the battery module 200; when the bracket 30 is in the second position, the positioning assembly 40 can be above the second position to facilitate pressing the electrode terminal 61 of the battery module 200.

[0124] The positioning assembly 40 can be movably provided on the bracket 30 so that the positioning assembly 40 is close to the battery module 200 and presses the electrode terminal 61; for example, when the bracket 30 is in the second position, the positioning assembly 40 is above the second position. At this time, the positioning assembly 40 can move toward the direction where the base plate 10 is located to press the electrode terminal 61; when the heating and pressurizing treatment of the battery module 200 is completed, the positioning assembly 40 can also move in the direction away from the base plate 10 to disengage from the electrode terminal 61.

[0125] During the process of the battery module 200 being transferred to the heating device 100, referring to Figure 2, the bracket 30 moves to the first position and is in the first position. At this time, the positioning assembly 40 is staggered with the second position and exposes at least part of the space above the second position. At the same time, the bracket 30 and the positioning assembly 40 are only on one side of the second position and avoid the space on the other side of the second position. At this time, the battery module 200 can be transferred to the second position on the side opposite to the bracket 30 in the second position; after the battery module 200 is transferred to the second position, referring to Figure 3, the bracket 30 moves to the second position and is in the second position. At this time, the positioning assembly 40 is above the battery module 200, the positioning assembly 40 is close to the battery module 200 and abuts against the electrode terminal 61; after the battery module 200 is heated and pressurized, the positioning assembly 40 moves away from the battery module 200 and detaches from the electrode terminal 61, and then the bracket 30 moves to the first position and is in the first position, so that the transferring equipment can transfer the battery module 200 to other positions.

[0126] In this embodiment, the positioning assembly 40 is enabled to be at least partially staggered with the second position when the bracket 30 is in the first position. At this time, the positioning assembly 40 and the bracket 30 are able to be on one side of the second position, while the upper part of the second position and the other side of the second position are left empty, so as to reduce the interference of the bracket 30 and the positioning assembly 40 in the transfer process of the battery module 200, and reduce the situation where the battery module 200 collides with the positioning assembly 40 or the bracket 30 during the transfer process; the positioning assembly 40 is enabled to be above the second position when the bracket 30 is in the second position, and the positioning assembly 40 is enabled to move toward the base plate 10 at this time to press and fix the battery module 200 on the base plate 10.

[0127] 2 and 4 , in some embodiments, when the bracket 30 moves to the first position, the orthographic projection of the positioning assembly 40 on the base plate 10 is staggered from the second position.

[0128] The orthographic projection of the positioning assembly 40 on the base plate 10 refers to the projection formed on the base plate 10 when the projection line of the positioning assembly 40 is perpendicular to the base plate 10 .

[0129] The staggered arrangement of the orthographic projection of the positioning assembly 40 on the base plate 10 and the second position means that the positioning assembly 40 and the carrier 20 are completely staggered and have no overlapping parts, and the positioning assembly 40 does not completely block the space above the carrier 20.

[0130] This setting enables the positioning assembly 40 to be fully exposed to the second position when the bracket 30 moves to the first position, thereby further reducing the interference of the positioning assembly 40 on the transfer process of the battery module 200, and also making it unnecessary for the battery module 200 to be raised to an excessively high position during the transfer process, thereby reducing the space occupied by the heating device 100.

[0131] In this embodiment, the positive projection of the positioning component 40 on the base plate 10 in the first position is staggered with that in the second position, so that the positioning component 40 can be completely staggered with the second position when in the first position, and the positioning component 40 will not block the space directly above the second position, thereby further reducing interference with the battery module 200 transfer process.

[0132] 2 , in some embodiments, the bracket 30 is movably disposed along the width direction of the base plate 10 , and the first position and the second position are sequentially arranged along the width direction of the base plate 10 .

[0133] The width direction of the bottom plate 10 is the direction of the Y axis in FIG. 2 .

[0134] The bracket 30 is movably arranged along the width direction of the base plate 10 , which means that the bracket 30 can move along the width direction of the base plate 10 .

[0135] The first position and the second position are sequentially arranged along the width direction Y of the base plate 10 , so that the bracket 30 can move along the width direction of the base plate 10 .

[0136] In order to reduce the interference of the positioning component 40 on the transfer process of the battery module 200, the positioning component 40 should be completely staggered with the second position. At this time, the bracket 30 is moved along the width direction Y of the base plate 10, which can reduce the distance that the bracket 30 travels during the movement of the positioning component 40 from the second position to the first position, thereby reducing the travel time of the bracket 30 and improving production efficiency.

[0137] In this embodiment, the bracket 30 is moved along the width direction of the base plate 10 to reduce the distance the bracket 30 moves, so that the positioning assembly 40 can move to the first position more quickly with the bracket 30, reducing interference with the battery module 200 transfer process and improving production efficiency.

[0138] 2 to 5 , in some embodiments, a first guide structure 11 and a first driving member 12 are provided on the base plate 10 , the bracket 30 is slidably connected to the first guide structure 11 , and the first driving member 12 is used to drive the bracket 30 to slide along the first guide structure 11 .

[0139] The first guide structure 11 refers to a structure in the heating device 100 that is mainly used to limit the movement direction of the bracket 30; the first guide structure 11 can be a slide groove opened on the base plate 10, and in this case, one end of the bracket 30 is slidably connected to the slide groove; the first guide structure 11 can also be a slide rail provided on the base plate 10, and in this case, the bracket 30 is slidably connected to the slide rail; the first guide structure 11 can also be a guide shaft passing through the bracket 30, and in this case, the bracket 30 can move along the guide shaft; it can be understood that the first guide structure 11 can also be other structures, not limited to the above-mentioned ones; in some embodiments, the first guide structure 11 is a slide rail.

[0140] The first driving member 12 refers to a structure in the heating device 100 that is mainly used to drive the bracket 30 to move. The first driving member 12 may include other linear feed structures such as a cylinder, a hydraulic cylinder, an electric cylinder, a motor-coordinated screw feed structure, a motor-coordinated gear rack structure, etc.; in some embodiments, the first driving member 12 is a cylinder.

[0141] The first driving member 12 is disposed on the base plate 10 and connected to the bracket 30 to drive the bracket 30 to slide along the first guide structure 11 .

[0142] This embodiment provides some specific structures in which the bracket 30 is movably disposed on the base plate 10 . The first driving member 12 can drive the bracket 30 to move along the first guide structure 11 , thereby driving the positioning assembly 40 to move synchronously.

[0143] According to some embodiments of the present application, referring to Figures 1 and 6 to 9, the positioning assembly 40 includes a first pressing structure 41 and a second pressing structure 42, and the first pressing structure 41 and the second pressing structure 42 are respectively used to press the electrode terminals 61 corresponding to the two poles of the battery module 200; the first pressing structure 41 can move relative to the second pressing structure 42 along a first direction to approach or move away from the second pressing structure 42.

[0144] The first pressing structure 41 refers to a structure in the heating device 100 used to press the electrode terminal 61 in the battery module 200. The first pressing structure 41 can move closer to the battery module 200 along with the positioning component 40 to press the electrode terminal 61. The first pressing structure 41 can also move away from the battery module 200 along with the positioning component 40 to detach from the electrode terminal 61.

[0145] The second pressing structure 42 is similar to the first pressing structure 41 , and is also used to press the electrode terminal 61 of the battery module 200 , and moves along with the positioning assembly 40 .

[0146] 1 , since a battery cell 60 typically has two electrode terminals 61 , namely a cathode and an anode, and the battery module 200 is composed of the battery cells 60 , the battery module 200 typically has two rows of electrode terminals 61 , and therefore a first pressing structure 41 and a second pressing structure 42 are provided to respectively press the two rows of electrode terminals 61 of the battery module 200 .

[0147] The number of the first pressing structure 41 and the second pressing structure 42 can both be one, in which case there can be only one row of battery cells 60 on the battery module 200; the number of the first pressing structure 41 and the second pressing structure 42 can both be two, in which case there can be two rows of battery cells 60 on the battery module 200, that is, there are four rows of electrode terminals 61 on the battery module 200 for pressing; it can be understood that the number of the first pressing structure 41 and the second pressing structure 42 can be determined according to the arrangement of the battery cells 60 in the battery module 200, and is not limited to the above-mentioned one or two.

[0148] The first and second pressing structures 41, 42 are arranged along a first direction to face the two rows of electrode terminals 61 of the battery module 200. The first direction is the arrangement direction of the two electrode terminals 61 on the battery cells 60. In some embodiments, the first direction is parallel to the width direction Y of the battery module 200.

[0149] The first pressing structure 41 can approach or move away from the second pressing structure 42 along the first direction. For example, the first pressing structure 41 and the second pressing structure 42 can both be movable structures, or the first pressing structure 41 can be a movable structure and the second pressing structure 42 can be a fixed structure.

[0150] The movement of the first pressing structure 41 can be driven by a structure such as a cylinder or a hydraulic cylinder, or the position of the first pressing structure 41 can be adjusted manually; when the second pressing structure 42 is movable, the second pressing structure 42 can also be driven by a structure such as a cylinder or a hydraulic cylinder, or the position of the first pressing structure 41 can be adjusted manually.

[0151] The first pressing structure 41 and the second pressing structure 42 may be directly connected to the bracket 30 , or the positioning assembly 40 or the bracket 30 may include other structural components, and the first pressing structure 41 and the second pressing structure 42 may be disposed on the structural component.

[0152] Because the distance between the two rows of electrode terminals 61 may be different in battery modules 200 of different specifications, the first pressing structure 41 can move relative to the second pressing structure 42 to adapt to battery modules 200 of different specifications; for example, when heating the battery module 200, the second pressing structure 42 can also be made opposite to one row of electrode terminals 61 of the battery module 200, and then the position of the first pressing structure 41 can be adjusted and made opposite to the other row of electrode terminals 61 to press the two rows of electrode terminals 61 of the battery module 200.

[0153] In this embodiment, the positioning assembly 40 includes a first pressing structure 41 and a second pressing structure 42, so that the electrode terminals 61 at different positions are pressed by the first pressing structure 41 and the second pressing structure 42 respectively; the first pressing structure 41 is movable relative to the second pressing structure 42, so that the first pressing structure 41 and the second pressing structure 42 can adapt to a variety of different specifications of battery modules 200, thereby being able to press the electrode terminals 61 of a variety of different specifications of battery modules 200.

[0154] Referring to Figures 7 to 10, in some embodiments, the first pressing structure 41 includes a first base 411 that can approach or move away from the second pressing structure 42, and at least two first pressing members 412 are provided on the first base 411 in sequence along the second direction. The first pressing members 412 are used to press at least two electrode terminals 61 of the battery module 200 arranged in the second direction; the second direction is perpendicular to the first direction.

[0155] The first base 411 refers to a structure in the first pressing structure 41 that is used to provide a fixed foundation for structures such as the first pressing member 412. The first base 411 can be a plate-like structure, such as a square plate, a circular plate, a strip plate or a plate structure of other shapes. The first base 411 can also be a columnar structure, such as a prismatic, cylindrical or other shaped column structure. The material of the first base 411 may include metal, plastic or other materials.

[0156] The first pressing member 412 refers to the structure in the first pressing structure 41 for pressing the electrode terminal 61 . The material of the first pressing member 412 may include metal, plastic or other materials; the shape of the first pressing member 412 may be cylindrical, prismatic or other shapes.

[0157] The first pressing member 412 can press at least two electrode terminals 61 arranged along the second direction, that is, one first pressing member 412 can press two or more electrode terminals 61 in the same row.

[0158] This arrangement enables the first pressing member 412 to adapt to battery modules 200 of various specifications. For example, when pressing a battery module 200 of smaller size, the first pressing member 412 can press three adjacent electrode terminals 61 in the same row, while when pressing a battery module 200 of larger size, the first pressing member 412 can press two adjacent electrode terminals 61 in the same row.

[0159] This arrangement also enables the electrode terminals 61 held by the same first pressing member 412 to be subjected to the same or substantially the same pressing force.

[0160] The second direction refers to the arrangement direction of the electrode terminals 61 in the battery module 200 , and is also the arrangement direction of the battery cells 60 in the battery module 200 . In some embodiments, the second direction is parallel to the length direction X of the heating device 100 .

[0161] In this embodiment, the positioning assembly 40 includes a first pressing structure 41 and a second pressing structure 42, so that the electrode terminals 61 at different positions are pressed by the first pressing structure 41 and the second pressing structure 42 respectively; the first pressing structure 41 is movable relative to the second pressing structure 42, so that the first pressing structure 41 and the second pressing structure 42 can adapt to a variety of different specifications of battery modules 200, thereby being able to press the electrode terminals 61 of a variety of different specifications of battery modules 200.

[0162] 7 to 10 , in some embodiments, a first elastic member 413 is disposed between the first pressing member 412 and the first base 411 .

[0163] The first elastic member 413 refers to an elastic structure in the first holding structure 41 ; the first elastic member 413 may be a spring, a rubber column or other elastic structure; the material of the first elastic member 413 may include metal, plastic or other elastic materials.

[0164] The first elastic member 413 is arranged between the first pressing member 412 and the first base 411, that is, one end of the first elastic member 413 is connected to the first pressing member 412, and the other end of the first elastic member 413 is connected to the base; the first elastic member 413 can be detachably connected to the first pressing member 412 and the first base 411 by snap connection, screw connection, etc., and the first pressing member 412 can also be fixedly connected to the first pressing member 412 and the first base 411 by bonding, welding, etc.

[0165] When the first pressing structure 41 approaches the battery module 200, the first base 411, the first elastic member 413 and the first pressing member 412 simultaneously approach the battery module 200 until the first pressing member 412 contacts the electrode terminal 61 of the battery module 200; when the first pressing member 412 contacts the electrode terminal 61, the first base 411 continues to approach the battery module 200, and at this time the first elastic member 413 is pressurized, and the elastic force of the first elastic member 413 acts on the first pressing member 412, so that the first pressing member 412 can be pressed on the electrode terminal 61.

[0166] In this embodiment, the first elastic member 413 is arranged between the first pressing member 412 and the first base 411. After the first pressing member 412 contacts the electrode terminal 61, the first base 411 can continue to move toward the direction close to the battery module 200 to compress the first elastic member 413, and enable the first elastic member 413 to apply pressure to the electrode terminal 61 through the first pressing member 412 to improve the pressing effect; at the same time, the first elastic member 413 can also provide a buffer when the first pressing member 412 presses on the electrode terminal 61, so as to reduce the collision damage that may be caused to the electrode terminal 61 when the first pressing member 412 contacts the electrode terminal 61.

[0167] Referring to Figure 11, in some embodiments, the second pressing structure 42 includes a second base 421, and at least two second pressing members 422 are provided on the second base 421 in sequence along the second direction. The second pressing members 422 are used to press at least two electrode terminals 61 of the battery module 200 arranged in the second direction; the second direction is perpendicular to the first direction.

[0168] The second base 421 refers to a structure in the second pressing structure 42 that is used to provide a fixed foundation for structures such as the second pressing member 422. The second base 421 can be a plate-like structure, such as a square plate, a circular plate, a strip plate or a plate structure of other shapes. The second base 421 can also be a columnar structure, such as a prismatic, cylindrical or other shaped column structure. The material of the second base 421 may include metal, plastic or other materials.

[0169] The second pressing member 422 refers to the structure in the second pressing structure 42 for pressing the electrode terminal 61. The material of the second pressing member 422 may include metal, plastic or other materials; the shape of the second pressing member 422 may be cylindrical, prismatic or other shapes.

[0170] The second pressing member 422 can press at least two electrode terminals 61 arranged along the second direction, that is, one second pressing member 422 can press two or more electrode terminals 61 in the same row.

[0171] Similar to the first pressing structure 41, the second pressing member 422 can adapt to battery modules 200 of various specifications. For example, when the second pressing member 422 presses a battery module 200 of smaller size, it can press three adjacent electrode terminals 61 in the same row, and when the second pressing member 422 presses a battery module 200 of larger size, it can press two adjacent electrode terminals 61 in the same row.

[0172] Similar to the first pressing structure 41 , each electrode terminal 61 pressed by the same second pressing member 422 can be subjected to the same or substantially the same pressing force.

[0173] Similar to the first pressing structure 41, in this embodiment, each second pressing member 422 is capable of pressing two or more electrode terminals 61, that is, the second pressing member 422 has a certain length in the arrangement direction of the electrode terminals 61. When the spacing between the electrode terminals 61 on battery modules 200 of different specifications is different, this setting does not need to be adjusted and can still press the electrode terminals 61; having more than two second pressing members 422 can prevent the length of each second pressing member 422 in the arrangement direction of the electrode terminals 61 from being too long, thereby reducing the occurrence of uneven pressing by the second pressing members 422.

[0174] 11 , in some embodiments, a second elastic member 423 is disposed between the second pressing member 422 and the second base 421 .

[0175] The second elastic member 423 refers to an elastic structure in the second holding structure 42 ; the second elastic member 423 may be a spring, a rubber column or other elastic structure; the material of the second elastic member 423 may include metal, plastic or other elastic materials.

[0176] The second elastic member 423 is arranged between the second pressing member 422 and the second base 421, that is, one end of the second elastic member 423 is connected to the second pressing member 422, and the other end of the second elastic member 423 is connected to the base; the second elastic member 423 can be detachably connected to the second pressing member 422 and the second base 421 by snap connection, screw connection, etc., and the second elastic member 423 can also be fixedly connected to the second pressing member 422 and the second base 421 by bonding, welding, etc.

[0177] When the second pressing structure 42 approaches the battery module 200, the second base 421, the second elastic member 423 and the second pressing member 422 simultaneously approach the battery module 200 until the second pressing member 422 contacts the electrode terminal 61 of the battery module 200; when the second pressing member 422 contacts the electrode terminal 61, the second base 421 continues to approach the battery module 200, and at this time the second elastic member 423 is pressurized, and the elastic force of the second elastic member 423 acts on the second pressing member 422, so that the second pressing member 422 can be pressed on the electrode terminal 61.

[0178] Similar to the first pressing structure 41, in this embodiment, after the second pressing member 422 contacts the electrode terminal 61, the second base 421 can continue to move toward the direction close to the battery module 200 to compress the second elastic member 423, and apply pressure to the electrode terminal 61 through the second elastic member 423 to improve the pressing effect; at the same time, the second elastic member 423 can also provide a buffer when the second pressing member 422 is pressed on the electrode terminal 61, so as to reduce the collision damage that may be caused to the electrode terminal 61 when the second pressing member 422 contacts the electrode terminal 61.

[0179] 9 , in some embodiments, there are two first pressing structures 41 and two second pressing structures 42 , and the two second pressing structures 42 are adjacently disposed, and the second pressing structure 42 is located between the two first pressing structures 41 .

[0180] The two first pressing structures 41 are adjacently arranged, that is, the two first pressing structures 41 are close to each other, and there is no second pressing structure 42 between the two first pressing structures 41 .

[0181] The second pressing structure 42 is located between the two first pressing structures 41 , that is, the two second pressing structures 42 are respectively located outside the two first pressing structures 41 , and the two first pressing structures 41 are located between the two second pressing structures 42 .

[0182] Because the battery module 200 usually includes two rows of battery cells 60, that is, the battery module 200 includes four rows of electrode terminals 61 at this time; in this arrangement, the two second pressing structures 42 are adjacent and located between the two first pressing structures 41. When the positioning assembly 40 is pressed on the battery module 200, the two second pressing structures 42 can be first made opposite to the two middle rows of electrode terminals 61 of the battery module 200; and then the positions of the two second pressing structures 42 can be adjusted.

[0183] In this embodiment, there are two first pressing structures 41 and two second pressing structures 42 , so that the positioning assembly 40 can press the battery module 200 having two battery cells 60 in the first direction or four electrode terminals 61 in the first direction.

[0184] Referring to Figures 6 to 9, in some embodiments, the positioning assembly 40 also includes a substrate 43, which is movably disposed on the bracket 30 and is used to move toward or away from the base plate 10; the first pressing structure 41 and the second pressing structure 42 are both disposed on the substrate 43.

[0185] The substrate 43 refers to a structure in the positioning assembly 40 used to provide a fixed foundation for the first pressing structure 41 and the second pressing structure 42, that is, the first pressing structure 41, the second pressing structure 42 or other structures can be arranged on the substrate 43; for example, the first base 411 and the second base 421 are both arranged on the substrate 43.

[0186] The shape of the substrate 43 may be square, circular or other shapes; the material of the substrate 43 may include metal, plastic or other structures.

[0187] The substrate 43 can move toward the direction approaching the battery module 200 to drive the first pressing structure 41 and the second pressing structure 42 to approach the battery module 200; the substrate 43 can also move toward the direction away from the battery module 200 to drive the first pressing structure 41 and the second pressing structure 42 to move away from the battery module 200.

[0188] In this embodiment, the substrate 43 serves as a fixing base for the first pressing structure 41 , the second pressing structure 42 and other structures, so that the first pressing structure 41 and the second pressing structure 42 can be driven to move closer to or away from the battery module 200 by driving the substrate 43 .

[0189] 6 to 9 , in some embodiments, the positioning assembly 40 further includes a second driving member 45 disposed on the bracket 30 . The second driving member 45 is used to drive the substrate 43 to move relative to the bracket 30 .

[0190] The second driving member 45 refers to the structure in the positioning assembly 40 that is mainly used to drive the bracket 30 to move. The second driving member 45 may include a cylinder, a hydraulic cylinder, an electric cylinder or other linear feed devices. The second driving member 45 may also include other linear feed structures such as a motor and a screw feed structure, a motor and a gear rack structure; in some embodiments, the second driving member 45 is a cylinder.

[0191] The second driving member 45 is disposed on the bracket 30 and connected to the base plate 43 , so as to drive the base plate 43 to move toward or away from the battery module 200 .

[0192] In this embodiment, the second driving member 45 drives the substrate 43 to move relative to the bracket 30 , thereby driving the first pressing structure 41 and the second pressing structure 42 to press the electrode terminal 61 .

[0193] 7 and 9 , in some embodiments, the first pressing structure 41 is movably connected to the base plate 43 along a first direction, and the second pressing structure 42 is fixedly connected to the base plate 43 .

[0194] The first pressing structure 41 is movably connected to the substrate 43 along a first direction. For example, a sliding groove is provided on the substrate 43, so that the first base 411 can slide in the sliding groove, so that the first pressing structure 41 can slide along the sliding groove relative to the substrate 43; for another example, a guide shaft is provided on the substrate 43, and the guide shaft passes through the first base 411, so that the first base 411 can slide along the guide shaft relative to the substrate 43, so that the first pressing structure 41 can slide along the guide shaft relative to the substrate 43; it can be understood that the first pressing structure 41 can also be movably connected to the substrate 43 in other ways.

[0195] The second holding structure 42 is fixedly connected to the substrate 43 . For example, the second base 421 may be fixedly connected to the substrate 43 . The second base 421 may be fixedly connected to the substrate 43 by welding, gluing, or the like.

[0196] When it is necessary to press the positioning assembly 40 against the electrode terminal 61, the second pressing structure 42 can be made opposite to a row of electrode terminals 61 by adjusting the position of the bracket 30, and then the position of the first pressing structure 41 can be adjusted so that the first pressing structure 41 is opposite to another row of electrode terminals 61, and then the substrate 43 can be moved in a direction close to the battery module 200; it can be understood that when the heating device 100 is in use, the specifications of the battery module 200 that is heated and pressurized within a period of time are usually the same, so it is only necessary to adjust the position of the first pressing structure 41 when the specifications of the battery module 200 change, and there is no need for frequent adjustment.

[0197] In this embodiment, the second pressing structure 42 is fixed relative to the substrate 43, and the first pressing structure 41 is movable relative to the substrate 43.
