[0001] This application claims priority to the Chinese patent application filed with the Patent Office of China on March 7, 2024, with application number 202420442100.9 and invention name “Heating device and battery processing system”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present application belongs to the field of power battery technology, and in particular relates 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 battery reliability. During the process of transporting the battery module to the heating device, the battery module is prone to collision with the heating device's positioning structure, which can easily cause damage to the battery module.

[0005] Summary of the Invention

[0006] In view of the above problems, the present application provides a heating device and a battery processing system, which can reduce damage to the battery module during placement in the heating device.

[0007] In a first aspect, some embodiments of the present application provide a heating device for heating a battery module, comprising:

[0008] A carrier, used for carrying a battery module;

[0009] A first limiting member is provided on at least one side of the carrier along the first direction, and is used to abut against the side surface of the battery module;

[0010] A heating component is provided on two opposite sides of the carrier along the first direction.

[0011] In the technical solution of this embodiment, the battery module is supported by a carrier, and when the battery module is placed on the carrier, the first limiting member can contact the battery module along the first direction to limit the displacement of the battery module in the first direction, so as to limit the position of the battery module on the carrier, thereby fixing the battery module; at the same time, the first limiting member located on the side can reduce the collision with the battery module, and can also reduce the structural damage and failure caused by the collision, so that the first limiting member can provide the limiting function more stably.

[0012] In some embodiments, the heating assembly includes a heating element that is movable along a first direction and is disposed on one side of the carrier. The heating element is provided with a avoiding structure that is opposite to the first limiting member.

[0013] In the technical solution of this embodiment, since the first limiting member is arranged on the side of the supporting member, and the heating member needs to heat the side of the battery module, a avoidance structure is provided on the heating member so that when the heating member approaches and abuts against the battery module, the avoidance structure can be opposite to the first limiting member, so that the heating member can be closer to the battery module or abut against the battery module, and the heating member can better heat the battery module.

[0014] In some embodiments, the avoidance structure is a through hole penetrating the heating element.

[0015] In the technical solution of this embodiment, the avoidance structure is a through hole that passes through the heating element. When the heating element approaches the battery module, the first limiting element can pass through the heating element at the through hole to further reduce the restriction of the first limiting element on the movement of the heating element, and enable the heating element to be closer to the battery module or close to the battery module, so as to facilitate heating and better heating of the battery module.

[0016] In some embodiments, the first limiting member is disposed on two opposite sides of the supporting member along the first direction.

[0017] The technical solution of this embodiment enables the first limiting member to limit the position of the battery module on the carrier from two opposite sides of the battery module, thereby reducing the movable space of the battery module in the first direction and better fixing the position of the battery module.

[0018] In some embodiments, a second limiting member is further provided on the carrier, and the second limiting member and the first limiting member are respectively used to abut against adjacent side surfaces of the battery module.

[0019] In the technical solution of this embodiment, a second limiting member is provided and the second limiting member and the first limiting member respectively abut against different sides of the battery module, so that the second limiting member and the first limiting member can respectively limit the displacement of the battery module in different directions, thereby further limiting the position of the battery module on the carrier.

[0020] In some embodiments, at least two second limiting members are provided on the carrier, and the at least two second limiting members are spaced apart along the second direction to abut against different sides of the battery module;

[0021] The second direction is arranged at an angle to the first direction.

[0022] The technical solution of this embodiment enables the second limiting member to limit the position of the battery module on the carrier from opposite sides of the battery module, thereby reducing the movable space of the battery module in the second direction and better fixing the position of the battery module.

[0023] In some embodiments, at least one accommodating space is defined between two adjacent second limiting members in the second direction, and the accommodating space is used to accommodate the battery module. At least two first limiting members are provided on both sides of the accommodating space along the first direction.

[0024] In the technical solution of this embodiment, there are at least two first limit members on both sides of the accommodating space along the first direction. Since the first limit members are mainly used to support the side of the battery module, and the length of the side of the battery module is usually longer, it is easy for the battery module to rotate and offset around the first limit member if only one first limit member is used. Therefore, this embodiment provides at least two first limit members on either side of the accommodating space along the first direction to further limit the position of the battery module on the carrier.

[0025] In some embodiments, at least two installation positions are provided on the carrier, the second position-limiting member is detachably connected to the carrier, and the second position-limiting member can be located in any installation position.

[0026] In the technical solution of this embodiment, the second limiting member has at least two different installation positions on the carrier, so that the second limiting member can adjust its position according to the different sizes of the battery module, so that the heating device can be compatible with battery modules of different sizes and specifications, thereby improving the compatibility of the heating device.

[0027] In some embodiments, the first limiting member includes a first base and a soft first abutting portion, the first base is connected to the supporting member, and the first abutting portion is connected to a side of the first base facing the supporting member.

[0028] The technical solution of this embodiment makes the first limiting member include a first supporting portion facing the battery module, and makes the first supporting portion a soft component. When the battery module is placed on the carrier, the soft first supporting portion can reduce the damage caused by the collision between the battery module and the first limiting member, and can also reduce the friction damage between the first limiting member and the battery module after the battery module is placed on the carrier, thereby playing a role in protecting the battery module.

[0029] In some embodiments, the first position-limiting member includes a first abutting surface and a first guiding surface, and the first abutting surface is provided on a side of the first position-limiting member facing the supporting member;

[0030] The first guide surface is inclined relative to the first abutting surface. One end of the first guide surface is connected to an end of the first abutting surface away from the supporting member, and the other end of the first guide surface extends in a direction away from the supporting member and the first abutting surface.

[0031] In the solution of this embodiment, the first limiting member includes an inclined first guide surface. During the process of placing the battery module on the carrier, the first guide surface can guide and correct the position of the battery module so that the battery module can be placed in a preset position and the collision between the battery module and the first limiting member can be reduced.

[0032] In some embodiments, the second limiting member includes a second base and a soft second abutting portion, the second base is connected to the supporting member, and the second abutting portion is connected to a side of the second base facing the supporting member.

[0033] The technical solution of this embodiment makes the second limiting member include a second supporting portion facing the battery module, and makes the second supporting portion a soft component. When the battery module is placed on the carrier, the soft second supporting portion can reduce the damage caused by the collision between the battery module and the second limiting member, and can also reduce the friction damage between the second limiting member and the battery module after the battery module is placed on the carrier, thereby playing a role in protecting the battery module.

[0034] In some embodiments, the second position-limiting member includes a second abutting surface and a second guiding surface, and the second abutting surface is provided on a side of the second position-limiting member facing the supporting member;

[0035] The second guide surface is inclined relative to the second abutting surface. One end of the second guide surface is connected to an end of the second abutting surface away from the supporting member, and the other end of the second guide surface extends in a direction away from the supporting member and the second abutting surface.

[0036] In the technical solution of this embodiment, the second limiting member includes an inclined second guide surface. During the process of placing the battery module on the carrier, the second guide surface can guide and correct the position of the battery module so that the battery module can be placed in a preset position and can reduce the collision between the battery module and the second limiting member.

[0037] In some embodiments, the heating device further comprises a frame, and the carrier and the heating assembly are both disposed on the frame;

[0038] The heating device also includes a driving structure arranged on the frame, and the driving structure is used for driving the heating element to move along the first direction.

[0039] The technical solution of this embodiment sets up a driving structure, and drives the heating element to move closer to or away from the battery module along a first direction through the driving structure, so that the heating element can be close to or in contact with the battery module to better heat the battery module. At the same time, it can also provide a certain pressure for the battery module, so that the heating element can play a role of heating and pressurizing.

[0040] In a second aspect, some embodiments of the present application further provide a battery processing system, comprising the heating device provided by some embodiments of the first aspect.

For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0059] 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.

[0060] During battery production and processing, the side panels and end plates of battery modules are often connected through welding or gluing. This connection process can leave gaps and other structures, resulting in loose connections between components. Furthermore, some structures within the battery module have lower charge and discharge efficiency at low temperatures, potentially leading to inefficient battery charging and discharging.

[0061] 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.

[0062] During the battery production and processing process, heating equipment is often used to heat and pressurize the battery module. During the heating and pressurization process, the battery module needs to be placed in a certain position so that all sides of the battery module can be more evenly stressed and heated.

[0063] In current heating equipment, battery cells are mostly positioned by a positioning pin structure. Specifically, there is a positioning hole at the bottom of the battery module (for example, at the bottom of the end plate). When the battery module is placed on the heating equipment, the positioning hole is aligned with the positioning pin and the positioning pin is inserted into the positioning hole.

[0064] This method places high demands on the equipment for placing the battery module; when the difference between the inner diameter of the positioning hole and the outer diameter of the positioning pin is small, the battery module is likely to bump into the positioning pin during placement and cause damage to the battery module, and it is also likely to cause damage to the positioning pin and affect subsequent construction; when the difference between the inner diameter of the positioning hole and the outer diameter of the positioning pin is large, the positioning effect of the positioning pin is poor.

[0065] Based on the above considerations, in order to reduce damage to the battery module during placement in the heating device, some embodiments of the present application provide a heating device, which supports the battery module through a carrier and provides a first limiting member on at least one side of the carrier along the first direction.

[0066] In such a heating device, the first limiter can limit the position of the battery module from the side. For example, the first limiter can limit the position of the battery module by abutting the side of the battery module without the need to use a pin-hole structure with high precision requirements for positioning, thereby reducing the need for positioning accuracy, thereby reducing the collision between the battery module and the heating device and reducing damage to the battery module.

[0067] In order to illustrate the technical solution described in this application, the following description is given with reference to specific drawings and embodiments.

[0068] In a first aspect, referring to FIG. 1 and FIG. 2 , some embodiments of the present application provide a heating device 100 for heating a battery module.

[0069] In FIG. 1 , the direction of the X-axis is the length direction of the heating device 100 , and the direction of the Y-axis is the width direction of the heating device 100 .

[0070] The heating device 100 includes a carrier 10, a first limiting member 11 and a heating component 20, wherein the carrier 10 is used to support the battery module; the carrier 10 is provided with a first limiting member 11 on at least one side along the first direction, and the first limiting member 11 is used to support the side of the battery module; the heating component 20 is provided on opposite sides of the carrier 10 along the first direction.

[0071] The carrier 10 refers to the structure in the heating device 100 that is mainly used to support the battery module. In addition to supporting the battery module, the carrier 10 is also used to provide a fixed foundation for structures such as the first limit member 11; the carrier 10 can be a plate-like structure, such as a square plate, a circular plate or a plate structure of other shapes. The carrier 10 can also be a columnar structure and form a platform, such as a cylindrical platform, a polygonal prism platform or a column structure of other shapes. The carrier 10 can also be a structure of other shapes; the material of the carrier 10 can include metal, plastic or other materials.

[0072] The heating component 20 refers to a structure in the heating device 100 for heating the battery module. The heating component 20 is arranged on opposite sides of the carrier 10 along the first direction to facilitate heating the battery module on the carrier 10; the heating component 20 may include a resistance wire structure and contact the battery module to achieve heating. The heating component 20 can also heat the battery module by hot air. The heating component 20 can also heat the battery module by other means.

[0073] The first limiter 11 refers to a structure in the heating device 100 for limiting the position of the battery module on the carrier 10; the first limiter 11 can be a columnar structure or a plate structure; the material of the first limiter 11 can include metal, plastic or other materials.

[0074] The carrier 10 is provided with a first limiting member 11 on at least one side along the first direction, and the first limiting member 11 is able to abut against the side of the battery module to limit the position of the first limiting member 11 on the carrier 10 by side positioning; accordingly, the first direction can be a direction perpendicular to the side of the battery module, for example, the first direction can be the direction where the Y-axis is located.

[0075] The first limiting member 11 can be provided on either side of the carrier 10, in which case the battery module can be in contact with the first limiting member 11 during placement to position the battery module; the first limiting member 11 can also be provided on both opposite sides of the carrier 10, in which case the battery module can be placed between the two first limiting members 11.

[0076] The first position-limiting member 11 can be fixedly connected to the carrier 10, for example, by welding, gluing, etc.; the first position-limiting member 11 can also be detachably connected to the carrier 10, for example, by snapping, screwing, etc.

[0077] The first limiting member 11 is held against the side of the battery module. Compared with the way in which the positioning pin cooperates with the hole structure in the battery module on the bottom surface of the battery module, the first limiting member 11 in this embodiment has lower requirements on the accuracy of the placement of the battery module, thereby reducing the possible damage caused by the placement error of the battery module.

[0078] This embodiment enables the first limiting member 11 to press against the battery module along the first direction to limit the displacement of the battery module in the first direction and limit the position of the battery module on the carrier 10, thereby fixing the battery module; at the same time, the first limiting member 11 located on the side can reduce the collision with the battery module, and can also reduce the structural damage and failure caused by the collision, so that the first limiting member 11 can provide a limiting function more stably.

[0079] According to some embodiments of the present application, referring to FIG. 2 and FIG. 4 , the heating assembly 20 includes a heating element 21 movable along a first direction and disposed on one side of the carrier 10 . The heating element 21 is provided with a avoiding structure 22 opposite to the first limiting element 11 .

[0080] The heating component 20 refers to the structure in the heating device 100 for heating the battery module, and the heating element 21 refers to the structure in the heating component 20 for heating the battery module. The heating element 21 can generate heat by energizing an electric heating device, or can generate heat by other means.

[0081] The heating element 21 can have a variety of structures. For example, the heating element 21 is a plate structure, and a heating wire or a heating medium channel is set in the plate structure; for another example, the heating element 21 can include series and / or parallel pipes, the pipes can be used for the flow of heating medium, and the pipes can also be used to accommodate the heating wire; it can be understood that the heating element 21 can also have other structures.

[0082] The heating element 21 can be movably arranged on one side of the carrier 10 along the first direction; for example, a slide rail can be provided on one side of the carrier 10, and the heating element 21 is slidably connected to the slide rail; for another example, a telescopic cylinder can be provided on one side of the carrier 10 to drive the heating element 21 to move relative to the carrier 10 through the telescopic cylinder; it can be understood that the carrier 10 can also be movably arranged on one side of the carrier 10 in other ways.

[0083] The heating element 21 can move along the first direction to approach or contact the battery module on the carrier 10 to heat the battery module.

[0084] The avoidance structure 22 refers to a structure that enables the heating element 21 to avoid the first limiting element 11 when approaching the battery module; the avoidance structure 22 can be a groove, a through hole or other structure, and can be specifically determined based on parameters such as the size of the first limiting element 11 in the first direction, the size of the heating element 21 in the first direction, and the distance between the heating element 21 and the battery module when heating the battery module.

[0085] Because the first limiting member 11 is arranged on one side of the supporting member 10 along the first direction, and the supporting member 10 is used to support the battery module, the heating member 21 is likely to collide with the first limiting member 11 when approaching the battery module along the first direction, and is blocked by the first limiting member 11 and is difficult to get closer to the battery module; and because the closer the heating member 21 is to the battery module, the better its heating effect and the higher its heating efficiency, and the farther the heating member 21 is from the battery module, the lower the heating efficiency, so the obstruction of the first limiting member 11 is likely to lead to a decrease in heating efficiency.

[0086] Accordingly, this embodiment provides an avoidance structure 22 on the heating element 21, and enables the avoidance structure 22 to be opposite to the first limiting member 11, so that when the heating element 21 approaches the battery module, the heating element 21 can avoid the first limiting member 11 at the avoidance structure 22, so as to reduce the obstruction of the heating element 21 by the first limiting member 11, so that the heating element 21 can be closer to the battery module or close to the battery module, thereby facilitating the heating element 21 to heat the battery module more efficiently.

[0087] 2 and 4 , in some embodiments, the avoidance structure 22 is a through hole penetrating the heating element 21 .

[0088] The through hole passes through the heating element 21 . The shape of the through hole may be square, circular, or other shapes. The shape of the through hole may be the same as that of the first limiting element 11 .

[0089] The main function of the through hole is to allow the first limiting member 11 to pass through so as to reduce the obstruction of the first limiting member 11 to the heating member 21. Accordingly, in order to reduce the collision between the first limiting member 11 and the heating member 21 when passing through the through hole, there should be a gap between the first limiting member 11 and the side wall of the through hole when it is in the through hole.

[0090] It is understandable that the through hole should not pass through the heating wire, pipe and other structures of the heating element 21 to reduce the negative impact of the through hole on the heating capacity of the heating element 21.

[0091] When the heating element 21 approaches the battery module along the first direction, the first limiting member 11 can pass through the heating element 21 at the through hole, thereby further reducing the obstruction of the heating element 21 approaching the battery module.

[0092] In this embodiment, the avoidance structure 22 is a through hole that passes through the heating element 21. When the heating element 21 approaches the battery module, the first limiting member 11 can pass through the heating element 21 at the through hole to further reduce the restriction of the first limiting member 11 on the movement of the heating element 21, and enable the heating element 21 to be closer to the battery module or close to the battery module, thereby facilitating heating and better heating of the battery module.

[0093] Referring to Figures 1 and 2, in some embodiments, the first limiting members 11 are arranged on opposite sides of the supporting member 10 along the first direction, that is, the first limiting members 11 are provided on both sides of the supporting member 10 along the first direction. The supporting member 10 may have only one first limiting member 11 on any side along the first direction, or may have two or more first limiting members 11; the number of first limiting members 11 on both sides of the supporting member 10 may be the same or different.

[0094] Since first limiting members 11 are provided on both sides of the carrier 10, the battery module can be placed between the first limiting members 11 on both sides of the carrier 10. The first limiting members 11 on both sides of the battery module can limit the movement space of the battery module in the first direction, so as to better fix the position of the battery module.

[0095] 5 and 6 , in some embodiments, the first limiting member 11 includes a first base 111 and a soft first abutting portion 112 . The first base 111 is connected to the carrier 10 , and the first abutting portion 112 is connected to the side of the first base 111 facing the carrier 10 .

[0096] The first base 111 refers to a structure in the first limiting member 11 used to provide a fixed foundation for other structures such as the first supporting portion 112. The first base 111 can be a plate-like structure, such as a square plate, a circular plate or a plate structure of other shapes. The first base 111 can also be a columnar structure, such as a cylindrical, prismatic or other shaped column structure. The first base 111 can also be an L-shaped or other special-shaped structure; the material of the first base 111 can include plastic, metal or other materials.

[0097] The first base 111 can be fixedly connected to the carrier 10, for example, by welding, gluing, etc.; the first base 111 can also be detachably connected to the carrier 10, for example, by snapping, screwing, etc.; in some embodiments, the first base 111 is detachably connected to the carrier 10 to facilitate replacement, maintenance and adjustment of the position of the first base 111 relative to the carrier 10.

[0098] The first supporting portion 112 refers to the structure in the first limiting member 11 that faces the battery module or contacts the battery module. The first supporting portion 112 can be a plate-like structure, such as a square plate, a circular plate or a plate structure of other shapes. The first supporting portion 112 can also be a columnar structure, such as a cylindrical, prismatic or other column structure. The first supporting portion 112 is a soft structure, and its material may include rubber, foam plastic or other soft materials.

[0099] The first supporting portion 112 is provided on the first base 111. The first supporting portion 112 can be fixedly connected to the first base 111, for example, fixedly connected to the first base 111 by gluing or the like; the first supporting portion 112 can also be detachably connected to the first base 111, for example, detachably connected to the first base 111 by snapping, screwing or the like.

[0100] The first abutting portion 112 is provided on the side of the first base 111 facing the carrier 10. When the battery module is placed on the carrier 10, if the position of the battery module changes, the battery module can first collide with the soft first abutting portion 112 to reduce damage to the battery module. At the same time, the soft first abutting portion 112 is not easily damaged and is easy to continue to use.

[0101] After the battery module is placed on the carrier 10 , if the battery module contacts the first limiting member 11 , the first abutting portion 112 can also reduce friction damage to the battery module caused by the first limiting member 11 , thereby further protecting the battery module.

[0102] In this embodiment, the first limiting member 11 includes a first abutting portion 112 facing the battery module, and the first abutting portion 112 is a soft component. When the battery module is placed on the carrier 10, the soft first abutting portion 112 can reduce the damage caused by the collision between the battery module and the first limiting member 11, and can also reduce the friction damage between the first limiting member 11 and the battery module after the battery module is placed on the carrier 10, thereby protecting the battery module.

[0103] 5 and 6 , in some embodiments, the first position-limiting member 11 includes a first abutting surface 113 and a first guide surface 114 , wherein the first abutting surface 113 is provided on the side of the first position-limiting member 11 facing the supporting member 10 ; the first guide surface 114 is inclined relative to the first abutting surface 113 , one end of the first guide surface 114 is connected to one end of the first abutting surface 113 away from the supporting member 10 , and the other end of the first guide surface 114 extends away from the supporting member 10 along the first direction.

[0104] The first abutting surface 113 refers to the surface of the first limiting member 11 facing the carrier 10. The main function of the first abutting surface 113 is to contact the battery module to limit the displacement of the battery module; the first abutting surface 113 can be perpendicular to the surface of the carrier 10 supporting the battery module, and can also be inclined relative to the surface of the carrier 10 supporting the battery module; the first abutting surface 113 can be a plane or a curved surface; in some embodiments, the first abutting surface 113 is a plane and perpendicular to the surface of the carrier 10 supporting the battery module, so that the first abutting surface 113 can be parallel to the side of the battery module.

[0105] The first guide surface 114 refers to the inclined surface on the first limiting member 11. One end of the first guide surface 114 is connected to the end of the first supporting surface 113 away from the supporting member 10, and the other end of the first guide surface 114 extends in the first direction away from the supporting member 10. At the same time, the other end of the first guide surface 114 also extends in the height direction of the first limiting member 11 away from the first supporting surface 113.

[0106] The main function of the first guide surface 114 is to guide the battery cell to be placed on the carrier 10 at a preset position on one side of the first limiter 11; when the first limiter 11 is only provided on one side of the carrier 10, the preset position refers to the position on the carrier 10 on one side of the first limiter 11, and when the battery cell is placed at the preset position, the first limiter 11 can be in contact with the battery module; when the first limiter 11 is provided on both sides of the carrier 10, the preset position refers to the position between the first limiters 11 on both sides of the carrier 10, and when the battery cell is placed at the preset position, the first limiter 11 can be in contact with the battery module and fix the battery module.

[0107] For example, a first limiting member 11 is provided on both sides of the carrier 10. When the battery module is placed on the carrier 10, if the position of the battery module is deflected in the first direction, the edge of the battery module can contact the first guide surface 114. As the battery module falls, the battery module can slide along the first guide surface 114 and finally fall between the first limiting members 11 on the opposite sides of the carrier 10.

[0108] In this embodiment, the first limiting member 11 includes an inclined first guide surface 114. During the process of placing the battery module on the carrier 10, the first guide surface 114 can guide and correct the position of the battery module so that the battery module can be placed in a preset position and can reduce the collision between the battery module and the first limiting member 11.

[0109] In some embodiments, when the first limiting member 11 includes the first base portion 111 and the first abutting portion 112 , the first guide surface 114 and the first abutting surface 113 are both formed on the first abutting portion 112 .

[0110] According to some embodiments of the present application, referring to FIG. 1 to FIG. 4 , a second limiting member 12 is further provided on the carrier 10 . The second limiting member 12 and the first limiting member 11 are respectively used to abut against adjacent side surfaces of the battery module.

[0111] The second limiter 12 refers to a structure in the heating device 100 for limiting the position of the battery module on the carrier 10; the second limiter 12 can be a columnar structure or a plate structure; the material of the second limiter 12 can include metal, plastic or other materials.

[0112] The second limiting member 12 and the first limiting member 11 are respectively used to support the adjacent side surfaces of the battery module to limit its activity space on the adjacent two sides of the battery module; when there are multiple first limiting members 11 and they are respectively arranged on the opposite sides of the battery module, and there are multiple second limiting members 12 and they are respectively arranged on the opposite sides of the battery module, the first limiting member 11 and the second limiting member 12 can limit the displacement of the battery module from four directions to roughly determine the position of the battery module on the carrier 10.

[0113] The number of the second limiting members 12 can be one, in which case the battery module can be abutted against the second limiting member 12 to determine the position of the battery module on the carrier 10; the number of the second limiting members 12 can also be two or more, in which case multiple second limiting members 12 can be respectively located on opposite sides of the battery module, further limiting the activity space of the battery module.

[0114] The second limiting member 12 can be fixedly connected to the carrier 10, for example, by welding, gluing, etc.; the second limiting member 12 can also be detachably connected to the carrier 10, for example, by snapping, screwing, etc.

[0115] In this embodiment, a second limiting member 12 is provided and the second limiting member 12 and the first limiting member 11 respectively abut against adjacent sides of the battery module, so that the second limiting member 12 and the first limiting member 11 can respectively limit the displacement of the battery module in different directions, thereby further limiting the position of the battery module on the carrier 10.

[0116] 2 and 3 , in some embodiments, at least two second limit members 12 are provided on the carrier 10 . The at least two second limit members 12 are spaced apart along the second direction to support different sides of the battery module. The second direction is arranged at an angle to the first direction.

[0117] The number of the second limiting members 12 may be two, or three or more; a plurality of second limiting members 12 are spaced apart on the carrier 10 so that a plurality of second limiting members 12 can be arranged on opposite sides of the battery module, thereby facilitating the second limiting members 12 on opposite sides of the battery module to better limit the displacement of the battery module.

[0118] The second limiting members 12 are arranged at intervals along the second direction and are respectively located on both sides of the battery module, so that the second limiting members 12 can abut against the opposite sides of the battery module to limit the position of the second limiting members 12 on the carrier 10 by side positioning; accordingly, the second direction can be a direction perpendicular to the side of the battery module.

[0119] The second limiting member 12 and the first limiting member 11 are respectively used to support adjacent sides of the battery module, that is, the second direction should not be parallel to the first direction, so that the second limiting member 12 and the first limiting member 11 can limit the position of the battery module on the carrier 10 from different directions respectively; in some embodiments, the second direction can be perpendicular to the first direction. For example, when the first direction is the direction of the Y-axis, the second direction can be the direction of the X-axis.

[0120] When there are at least two first limiting members 11 and they are arranged on opposite sides of the battery module, the first limiting members 11 and the second limiting members 12 can limit the displacement of the battery module on the carrier 10 from four directions to roughly determine the position of the battery module on the carrier 10, thereby reducing the movement of the battery module during the heating process.

[0121] In this embodiment, the second limiting member 12 can limit the position of the battery module on the carrier 10 from two opposite sides of the battery module, thereby reducing the movable space of the battery module in the second direction and better fixing the position of the battery module.

[0122] 3 , in some embodiments, at least one accommodating space 101 is defined between two adjacent second limiting members 12 in the second direction, and at least two first limiting members 11 are provided on both sides of the accommodating space 101 along the first direction.

[0123] The accommodating space 101 refers to a space on the carrier 10 for accommodating a battery module. The accommodating space 101 is defined between two second limiting members 12 adjacent to each other along the second direction. The accommodating space 101 is a space defined on the carrier 10 .

[0124] There may be only one, or two or more accommodating spaces 101 between two second limiting members 12 adjacent along the second direction; because the equipment for transferring battery modules (such as a robot) can transfer one battery module or two or more battery modules, there may be only one, or two or more accommodating spaces 101 between two second limiting members 12 adjacent along the second direction.

[0125] For example, when the distance between two second limiting members 12 adjacent to each other along the second direction remains unchanged, only one accommodating space 101 can be defined between the two. At this time, the battery module accommodated by the accommodating space 101 is larger in size in the second direction. At the same time, two accommodating spaces 101 can also be defined between two second limiting members 12 adjacent to each other along the second direction. At this time, the battery module accommodated by the accommodating space 101 is smaller.

[0126] At least two first limiting members 11 are provided on both sides of the accommodating space 101 along the first direction to better limit the displacement of the battery module in the accommodating space 101 in the first direction, and at the same time reduce the occurrence of rotational offset of the battery module in the accommodating space 101 around the first limiting member 11.

[0127] For example, when two accommodating spaces 101 are defined between two adjacent second limiting members 12 along the second direction, the carrier 10 is provided with at least four first limiting members 11 on both sides within the length range between the two adjacent second limiting members 12 along the second direction.

[0128] It can be understood that during the production and processing process, the size of the battery module corresponding to the heating device 100 is usually one or a limited number of sizes. The size and number of the accommodating space 101 are determined based on the minimum specification battery module corresponding to the heating device 100, and the number and arrangement of the first limiting members 11 are determined accordingly. At this time, when battery modules of various sizes are placed between two adjacent second limiting members 12 along the second direction, there can be at least two first limiting members 11 on both sides of each battery module.

[0129] In this embodiment, at least two first limiting members 11 are provided on both sides of the accommodating space 101 along the first direction. Since the first limiting member 11 is mainly used to support the side of the battery module, and the length of the side of the battery module is usually longer, it is easy for the battery module to rotate and offset around the first limiting member 11 when only one first limiting member 11 is used. Therefore, in this embodiment, at least two first limiting members 11 are provided on either side of the accommodating space 101 along the first direction to further limit the position of the battery module on the carrier 10.

[0130] 4 and 7 , in some embodiments, the second position-limiting member 12 includes a second base 121 and a soft second abutting portion 122 . The second base 121 is connected to the carrier 10 , and the second abutting portion 122 is connected to the side of the second base 121 facing the carrier 10 .

[0131] Similar to the first limiting member 11, the second base 121 refers to a structure in the second limiting member 12 used to provide a fixed foundation for other structures such as the second supporting portion 122. The second base 121 can be a plate-like structure, such as a square plate, a circular plate or a plate structure of other shapes. The second base 121 can also be a columnar structure, such as a cylindrical, prismatic or other shaped column structure. The second base 121 can also be an L-shaped or other special-shaped structure; the material of the second base 121 can include plastic, metal or other materials.

[0132] The second base 121 can be fixedly connected to the carrier 10, for example, by welding, gluing, etc.; the second base 121 can also be detachably connected to the carrier 10, for example, by snapping, screwing, etc.; in some embodiments, the second base 121 is detachably connected to the carrier 10 to facilitate replacement, maintenance and adjustment of the position of the second base 121 relative to the carrier 10.

[0133] The second supporting portion 122 refers to the structure in the second limiting member 12 that faces the battery module or contacts the battery module. The second supporting portion 122 can be a plate-like structure, such as a square plate, a circular plate or a plate structure of other shapes. The second supporting portion 122 can also be a columnar structure, such as a cylindrical, prismatic or other shaped column structure. The second supporting portion 122 is a soft structure, and its material may include rubber, foam plastic or other soft materials.

[0134] The second supporting portion 122 is provided on the second base 121. The second supporting portion 122 can be fixedly connected to the second base 121, for example, fixedly connected to the second base 121 by gluing or the like; the second supporting portion 122 can also be detachably connected to the second base 121, for example, detachably connected to the second base 121 by snapping, screwing or the like.

[0135] The second supporting portion 122 is provided on the side of the second base 121 facing the carrier 10. When the battery module is placed on the carrier 10, if the position of the battery module changes, the battery module can first collide with the soft second supporting portion 122 to reduce damage to the battery module. At the same time, the soft second supporting portion 122 is not easily damaged and can be used further.

[0136] After the battery module is placed on the carrier 10 , if the battery module contacts the second limiting member 12 , the second abutting portion 122 can further reduce friction damage to the battery module caused by the second limiting member 12 , thereby further protecting the battery module.

[0137] The technical solution of this embodiment enables the second limiting member 12 to include a second abutting portion 122 facing the battery module, and enables the second abutting portion 122 to be a soft component. When the battery module is placed on the carrier 10, the soft second abutting portion 122 can reduce the damage caused by the collision between the battery module and the second limiting member 12, and can also reduce the friction damage between the second limiting member 12 and the battery module after the battery module is placed on the carrier 10, thereby playing a role in protecting the battery module.

[0138] Referring to Figures 4 and 7, in some embodiments, the second limiting member 12 includes a second abutting surface 123 and a second guide surface 124, and the second abutting surface 123 is arranged on the side of the second limiting member 12 facing the supporting member 10; the second guide surface 124 is inclined relative to the second abutting surface 123, one end of the second guide surface 124 is connected to the end of the second abutting surface 123 away from the supporting member 10, and the other end of the second guide surface 124 extends in a direction away from the supporting member 10.

[0139] Similar to the first limiting member 11, the second supporting surface 123 refers to the surface of the second limiting member 12 facing the carrier 10. The main function of the second supporting surface 123 is to support the battery module to limit the displacement of the battery module; the second supporting surface 123 can be perpendicular to the surface of the carrier 10 supporting the battery module, or it can be inclined relative to the surface of the carrier 10 supporting the battery module; the second supporting surface 123 can be a plane or a curved surface; in some embodiments, the second supporting surface 123 is a plane and perpendicular to the surface of the carrier 10 supporting the battery module, so that the second supporting surface 123 can be parallel to the side of the battery module.

[0140] The second guide surface 124 refers to the inclined surface on the second limiting member 12, one end of the second guide surface 124 is connected to the end of the second supporting surface 123 away from the supporting member 10, and the other end of the second guide surface 124 extends in the second direction and in the height direction of the second limiting member 12 toward the direction away from the supporting member 10.

[0141] The main function of the second guide surface 124 is to guide the battery cell to be placed on the preset position on the carrier 10 on the side of the second limiter 12; when there is only one second limiter 12 on the carrier 10, the preset position refers to the position on the carrier 10 on the side of the second limiter 12, and when the battery cell is placed at the preset position, the second limiter 12 can be in contact with the battery module; when two or more second limiters 12 are spaced apart on the carrier 10, the preset position refers to the position between two adjacent and opposite second limiters 12, and when the battery cell is placed at the preset position, the second limiter 12 can be in contact with the battery module or there is a gap between the side of the battery module.

[0142] For example, two second limiting members 12 are spaced apart on the carrier 10. When the battery module is placed on the carrier 10, if the position of the battery module deviates in the second direction, the edge of the battery module can contact the second guide surface 124. As the battery module falls, the battery module can slide along the second guide surface 124 and finally fall between the second limiting members 12 on opposite sides of the carrier 10.

[0143] In this embodiment, the second limiting member 12 includes an inclined second guide surface 124. During the process of placing the battery module on the carrier 10, the second guide surface 124 can guide and correct the position of the battery module so that the battery module can be placed in a preset position and can reduce the collision between the battery module and the second limiting member 12.

[0146] The mounting position 102 refers to the position on the carrier 10 for installing the second limiting member 12, and the mounting position 102 is limited to the position on the carrier 10; according to the specific method of detachable connection of the second limiting member 12, a threaded hole, a snap or other structure that cooperates with the second limiting member 12 can be provided on the mounting position 102; in some embodiments, a threaded hole is provided on the mounting position 102 so that the second limiting member 12 can be detachably connected to the carrier 10 by bolts.

[0147] According to the size of the battery module to be heated by the heating device 100 , the second limiting member 12 can be located in different installation positions 102 , so that the heating device 100 can adapt to battery modules of various specifications, thereby increasing the compatibility of the heating device 100 .

[0148] In this embodiment, the second limiting member 12 has at least two different installation positions 102 on the carrier 10, so that the second limiting member 12 can adjust its position according to the different sizes of the battery modules, thereby making the heating device 100 compatible with battery modules of different sizes and specifications, thereby improving the compatibility of the heating device 100.

[0153] In this embodiment, a driving structure 23 is provided, and the driving structure 23 drives the heating element 21 to move toward or away from the battery module along a first direction, so that the heating element 21 can be close to or in contact with the battery module, so as to better heat the battery module. At the same time, it can also provide a certain pressure for the battery module, so that the heating element 21 can play a role of heating and pressurizing.

[0154] According to some embodiments of the present application, referring to Figures 1 to 4, the heating device 100 includes a frame 30, on which a carrier 10 is provided.
