[0069] As Figure 2 The battery device 100 provided by the embodiments of the present application is provided, the battery monomer 12 of the battery device 100 is an energy storage component and can perform charge and discharge reactions, at least one battery monomer 12 forms a battery monomer assembly 11, and the battery monomer assembly 11 is arranged in the box body 10 in the form of the battery monomer assembly 11, and the stability of the fixed battery monomer assembly 11 needs to be ensured.
[0070] In the related art, an end plate and a side plate are arranged at the end side of the battery monomer assembly, a connecting structure is arranged on the end plate or the side plate, and the battery monomer assembly is fixed by being connected in the box body through the connecting structure, for example, a threaded hole is formed on the end plate or the side plate, and a matching bolt is inserted, and the bolt is connected in the box body, and this connection form is inconvenient to disassemble.
[0071] Based on this, the present application provides a battery device 100, and the battery monomer assembly 11 of the battery device 100 can be quickly disassembled.
[0072] Please refer to Figures 2-6 The present application provides a specific embodiment of a battery device 100, and the battery device 100 of the embodiment includes a box body 10, a battery monomer assembly 11 and an adhesive body 14.
[0073] The box 10 is provided with a cavity; the battery cell assembly 11 is arranged in the cavity, the battery cell assembly 11 comprises a first plate body 13 and at least one battery cell 12, the first plate body 13 is connected to the side of the battery cell 12, the first plate body 13 is arranged adjacent to the inner wall of the box 10, and the space between the first plate body 13 and the inner wall of the box 10 is a first space 15, and a second space 16 is further arranged on the first plate body 13 or the side of the first plate body 13 facing the battery cell 12, the first space 15 and the second space 16 are in communication; the adhesive body 14 is arranged in the first space 15 to connect the first plate body 13 and the box 10, and the second space 16 is used to accommodate a cutting body so that the cutting body enters the first space 15 to cut the adhesive body 14.
[0074] The battery cell 12 and the first plate body 13 of the embodiment form a battery cell assembly 11, which is arranged inside the cavity. The first plate body 13 is arranged on the side of the battery cell 12 and is fixed relative to the battery cell 12, and the first plate body 13 is located between the battery cell 12 and the inner wall of the box 10.
[0075] Specifically, the box 10 forms a cavity capable of accommodating the battery cell assembly 11, and the battery cell assembly 11 is fixedly arranged inside the box 10. The first plate body 13 is arranged on the side of the battery cell 12, which refers to the part between the bottom side and the top side of the battery cell 12 in the direction of gravity, and can be understood as a vertical side part. When the battery cell 12 is multiple and arranged side by side, the first plate body 13 is arranged on the side part formed by the multiple battery cells 12. The first plate body 13 is located between the battery cell 12 and the inner wall of the box 10, and the inner wall of the box 10 refers to the wall of the box 10 opposite to the side of the battery cell 12. The first plate body 13 is fixed relative to the battery cell 12, which can increase the integrity of each battery cell 12, thereby strengthening the firmness of the battery cell assembly 11. The first plate body 13 can be connected with the battery cell 12 to form an integral whole, and when the first plate body 13 is connected and fixed with the box 10, the fixation of the entire battery cell assembly 11 in the box 10 is achieved.
[0076] The fixation between the first plate body 13 and the box 10 is achieved by using the adhesive body 14 for adhesion. The adhesive body 14 is a soft material with adhesive property, which can be a glue with adhesive property, and specifically can be structural glue, foaming glue, foam with adhesive property, etc. The adhesive body 14 respectively adheres the first plate body 13 and the inner wall of the box 10, thereby achieving the fixation of the battery cell assembly 11 in the box 10. In addition, when it is necessary to disassemble the battery cell assembly 11 from the inside of the box 10, the adhesive body 14 can be cut by a cutting body, so that the first plate body 13 is separated from the inner wall of the box 10.
[0077] In order to conveniently and quickly cut the bonding body 14, the second space 16 is provided, which provides a containing space for the cutting body and facilitates the cutting operation.
[0078] The cutting body is a separate device, which can be always stored in the second space 16 or can be placed in the second space 16 when the battery monomer assembly 11 needs to be disassembled. The cutting operation can be performed by the operator or by other power assemblies.
[0079] Specifically, the first space 15 is the gap between the first plate body 13 and the inner wall of the box body 10, which is used to set the bonding body 14. Specifically, the bonding body 14 can be extruded into the gap, and after the bonding body 14 solidifies, the connection between the inner wall of the box body 10 and the first plate body 13 can be achieved. The second space 16 is arranged at the first plate body 13, which can be a groove, a hole or other structures arranged on the first plate body 13 or located at the side of the first plate body 13 facing the battery monomer 12. Specifically, it can be a groove, a hole or other structures arranged on the first plate body 13, or it can be a hollow space formed based on the shape of the first plate body 13, such as when the side of the first plate body 13 facing the battery monomer 12 has a folding angle, the second space 16 can be formed at the folding angle. Alternatively, the second space 16 can be a space surrounded by the side of the first plate body 13 facing the battery monomer 12 and other structures, and the second space 16 can be used to contain the cutting body.
[0080] The second space 16 and the first space 15 are in communication with each other. The purpose of the second space 16 is not only to contain the cutting body, but also to serve as a cutting point, i.e. the cutting body first enters the second space 16, and then enters the first space 15 through the communicating part of the second space 16, so as to cut the bonding body 14. If the second space 16 is not provided, an effective cutting operation space cannot be provided inside the battery device 100, which makes the cutting operation inconvenient.
[0081] The effect of the embodiment is that, firstly, compared with the form of connecting the battery monomer assembly 11 and the box body 10 by connecting structure (such as bolt), the connecting by the adhesive body 14 and the cutting by the cutting body make the disassembly more convenient, only the adhesive body 14 needs to be cut, and the bolt does not need to be repeatedly disassembled, and the maintenance effect is improved; secondly, the adhesive body 14 needs to have a cutting point for cutting, and the internal space of the battery device 100 is limited and cannot meet the cutting demand, and the second space 16 is arranged based on the first plate body 13, that is, at the first plate body 13, and does not interfere with other electrical elements, and is communicated with the first space 15, and the cutting body is located in the second space 16, and can enter the first space 15 for cutting. The cutting body can be placed in the second space 16 or placed when disassembled, and the cutting body can adopt a filament structure, such as a steel wire, which is convenient for the cutting body to be placed, and the communication position of the first space 15 and the second space 16 can also be selected as needed. The communication position can be the position of cutting the adhesive body 14 first, so as to conveniently and quickly cut the adhesive body 14. Therefore, the second space 16 provided by the embodiment facilitates the cutting and greatly improves the disassembly efficiency; moreover, since the form of connecting by bolt is not adopted, the thick end plate and side plate for fixing the battery monomer 12 are also avoided, and the first plate body 13 does not need to be punched, but only needs to be adhered by the form of adhesion, so the thickness of the first plate body 13 can be appropriately reduced, the influence on the energy density of the battery device 100 is reduced, and the embodiment does not adopt the form of directly adhering the battery monomer 12, but the first plate body 13 is arranged, the battery monomer 12 is connected with the first plate body 13 and adhered through the first plate body 13, the integrity and firmness of the battery monomer 12 are increased, and the single battery monomer assembly 11 can be individually disassembled and maintained through cutting.
[0082] Please refer to Figures 3-6 , the two ends of the second space 16 can be the two ends of the first plate body 13 in the first direction, and the first direction is the horizontal extension direction of the first plate body 13, and the first direction is parallel to the surface of the first plate body 13 adhering the adhesive body 14. The first direction can be the arrangement direction of the plurality of battery monomers 12.
[0083] The first direction is the X direction in Figure 3 .
[0084] The second space 16 can be a hole or a groove communicating the two ends of the first plate body 13 in the first direction.
[0085] Specifically, the first direction of the first plate body 13 can be the direction with the maximum length of the first plate body 13.
[0086] Since the adhesive body 14 is adhered to the first plate body 13 and is arranged in the first space 15, the adhesive body 14 and the first space 15 can also extend along the first direction. The length of the adhesive body 14 in the first direction is less than or equal to the length of the first plate body 13 in the first direction. When the cutting body is located in the second space 16, such as when the cutting body is a steel wire or the like, a part of the cutting body can extend out of both ends of the second space 16 for holding and cutting operation, and the adhesive body 14 can be cut as a whole.
[0087] The second space 16 is connected to both ends of the first plate body 13, so that the cutting body is easily put in, the cutting body can be inserted from one end of the second space 16 and exposed from the other end, and the two exposed ends of the cutting body in the second space 16 can be held simultaneously during operation, and the cutting body can be inserted into the first space 15, so that the adhesive body 14 in the first space 15 can be cut as a whole.
[0088] In some embodiments, referring to Figures 3-6 , the second space 16 is located at the bottom of the first plate body 13 in the direction of gravity, and the second space 16 is connected to the bottom of the first space 15 in the direction of gravity.
[0089] Specifically, the embodiment provides the position of the second space 16, which is arranged at the bottom of the first plate body 13 in the direction of gravity, and the second space 16 is connected to the bottom of the first space 15 in the direction of gravity.
[0090] In the embodiment, the second space 16 is located at the bottom of the first plate body 13 in the direction of gravity, which means that the first plate body 13 is located at the lower position in the direction of gravity, which can not be the absolute bottom. Similarly, the second space 16 is connected to the bottom of the first space 15 in the direction of gravity, which also means that the first space 15 is located at the lower position in the direction of gravity. The specific position of the bottom of the two can be referred to the position of the adhesive body 14, which is the position lower than the bottom end of the adhesive body 14 in the direction of gravity.
[0091] The effect of the embodiment is that since the second space 16 is located at the bottom and connected to the bottom of the first space 15, the cutting body is also located at the bottom, and when the cutting body cuts the adhesive body 14, the cutting body can cut the adhesive body 14 from bottom to top, which is more convenient, only needs to lift the cutting body, and is more easy to operate than cutting the adhesive body 14 by pressing the cutting body downward.
[0092] In some embodiments, referring to Figures 3-6 , a separation piece 17 is arranged at the connection between the second space 16 and the first space 15 to block the adhesive body 14 from entering the second space 16, and the cutting body is also used to cut the separation piece 17.
[0093] Since the first space 15 and the second space 16 are communicated with each other, in order to prevent the adhesive body 14 from entering the second space 16, a partition 17 is arranged at the communication position. The partition 17 can be made of soft material, and only needs to block the adhesive body 14, and is easy to be cut by the cutting body. The partition 17 can be foam, a glue blocking strip, or a weak part with holes arranged integrally with the first plate body 13, so that the cutting body can enter the first space 15. In particular, when the communication position between the first space 15 and the second space 16 is at the bottom in the direction of gravity, the adhesive body 14 is more likely to enter the second space 16, so the partition 17 needs to be arranged.
[0094] Please refer to Figures 3-6 The partition 17 is arranged between the first plate body 13 and the bottom surface of the box body 10. Specifically, the partition 17 can be pressed between the two.
[0095] Specifically, when the second space 16 is at the bottom and communicates with the bottom of the first space 15, the communication position between the first space 15 and the second space 16 is preferably arranged at the bottom, so that when the partition 17 is arranged at the communication position, it can be pressed between the first plate body 13 and the bottom surface of the box body 10. In this way, not only the firmness of the partition 17 is improved, but also the first plate body 13 is supported to a certain extent.
[0096] In some embodiments, the cutting body is a wire-shaped structure made of metal material.
[0097] Specifically, the cutting body is wire-shaped. The adhesive body 14 can be a soft gel structure, and the adhesive body 14 is laid in an unfolded form in the first space 15 to increase the adhesive area with the structures on both sides. For this purpose, the cutting body is preferably an elongated wire-shaped structure, which is convenient for cutting the adhesive body 14. Therefore, the cutting body in this embodiment is wire-shaped, which can be a wire-shaped structure made of metal material, specifically a steel wire or a gold wire, which is sufficient to cut the adhesive body 14. When cutting, the two ends of the cutting body can be held and passed through the adhesive body 14 to complete the cutting of the adhesive body 14.
[0098] The shape of the cutting body in this embodiment is selected to facilitate the cutting of the adhesive body 14. Without using a complex structure or a large volume, a wire-shaped structure can meet the requirements and is simple in structure and easy to operate.
[0099] The shape of the second space 16 can be adapted to the shape of the cutting body.
[0100] Specifically, first, when the shape of the second space 16 is adapted to the shape of the cutting body, the cutting body can be better accommodated, and the space occupation of the second space 16 is reduced as much as possible, and the influence on the energy density is reduced.
[0101] Further, when the cutting body enters the first space 15 from the second space 16, the cutting body is in a cutting state, the second space 16 is set to a shape suitable for the cutting body, and the setting state of the cutting body can be limited. For example, when the cutting body is a steel wire in a wire shape, the second space 16 is set to a long strip shape suitable for the cutting body, and the cutting body enters the second space 16 in a straight and unfolded state. Thus, the adhesive body 14 can be better cut when the cutting body enters the first space 15.
[0102] When the shape of the second space 16 is suitable for the shape of the cutting body, the occupied space of the second space 16 can be saved, the influence on the energy density can be reduced, and the setting state of the cutting body can be limited. The cutting body can enter the first space 15 to perform cutting.
[0103] In some embodiments, referring to Figure 3 At least two first plate bodies 13 are arranged on opposite sides of the battery monomer 12.
[0104] One of the effects of the first plate body 13 is to strengthen the integrity of the plurality of battery monomers 12 and to strengthen the firmness of the fixing of the battery monomer assembly 11. In order to strengthen this effect, at least two first plate bodies 13 are arranged on opposite sides of the plurality of battery monomers 12 to form a clamping form for the plurality of battery monomers 12. In addition, the two first plate bodies 13 can be connected to each other to form a whole.
[0105] In some embodiments, the first plate body 13 can be a plurality of plate bodies arranged around the battery monomer 12 and connected to form a frame.
[0106] The first plate body 13 can be a plurality of plate bodies, and the plurality of first plate bodies 13 are connected to each other and form a frame arranged around the battery monomer 12.
[0107] The plurality of first plate bodies 13 can be connected end to end and arranged around the battery monomer 12 in a wrapping form to form a frame structure.
[0108] The arrangement of the embodiment further strengthens the integrity of the plurality of battery monomers 12 in the battery monomer assembly 11 and the firmness of the fixing of the battery monomer assembly 11.
[0109] The battery monomer assembly 11 further comprises a second plate body, and the second plate body is connected to the first plate body 13 and forms a frame arranged around the battery monomer 12.
[0110] Specifically, the plurality of battery cells 12 of the battery cell assembly 11 can not be adjacent to the inner wall of the box 10 on each side, when the battery cell assembly 11 is multiple, the side of the battery cell 12 can be adjacent to another battery cell assembly 11, so for this case, the first plate body 13 does not need to be provided here, so the second plate body is provided in the embodiment, and the second plate body is connected with the first plate body 13 to form a frame, which also plays a role in strengthening the integrity of the plurality of battery cells 12.
[0111] In some embodiments, referring to Figures 3-6 , the first plate body 13 includes a main body part 131 and a protruding part 132, the main body part 131 is attached to the battery cell 12, and the protruding part 132 is provided on the side of the main body part 131 away from the battery cell 12, and the adhesive body 14 is provided between the protruding part 132 and the inner wall of the box 10.
[0112] Specifically, the first plate body 13 includes a main body part 131 and a protruding part 132, the main body part 131 is used to attach the battery cell 12, which can be in direct contact and compression with the battery cell 12, or a foam or other intermediate structure can be provided between the two, the main body part 131 is relatively fixed with the battery cell 12, and the protruding part 132 is used to provide the adhesive body 14 between the box 10 inner wall, and the main body part 131 and the protruding part 132 can be an integrated structure connected with each other.
[0113] The effect of the embodiment is that the first plate body 13 is provided with two parts, the main body part 131 can be provided to match the shape of the side of the battery cell 12, and the protruding part 132 can be provided to form the second space 16 as needed, and has a surface opposite to the inner wall of the box 10 to provide the adhesive body 14, both of which play different functions, the main body part 131 is attached to the battery cell 12, and the structure strength of the main body part 131 is not affected by the second space 16. The protruding part 132 is not attached to the battery cell 12, and its structure state can be freely set to facilitate the setting of the second space 16 and the good adhesion to the inner wall of the box 10.
[0114] In some embodiments, referring to Figures 3-6 , the area of the surface of the protruding part 132 facing the inner wall of the box 10 is smaller than the area of the surface of the main body part 131 facing the inner wall of the box 10.
[0115] The surface of the protruding part 132 facing the inner wall of the box 10 is the surface on which the adhesive body 14 is provided, and the area of this surface is smaller than the area of the surface of the main body part 131 facing the inner wall of the box 10, because the adhesive body 14 can not be too much, and can play a connecting and fixing role, so the area of the surface of the protruding part 132 is smaller, which can meet the use requirement, save materials, and the smaller protruding part 132 also improves the energy density to some extent.
[0116] In some embodiments, referring to Figures 3-6 , the length of the protruding portion 132 in the horizontal direction parallel to the surface of the protruding portion 132 to which the adhesive body 14 is adhered is a first length, the length of the main body portion 131 in the horizontal direction parallel to the surface of the protruding portion 132 to which the adhesive body 14 is adhered is a second length, and the first length is equal to the second length.
[0117] Specifically, the adhesive body 14 is arranged between the protruding portion 132 and the inner wall of the box body 10, and the adhesive body 14 can be arranged on the surface of the protruding portion 132 facing the inner wall of the box body 10. Since the first length is equal to the second length, the relative fixation between the main body portion 131 and the inner wall of the box body 10 in the length direction can be achieved, and the firmness of the fixation is increased.
[0118] In some embodiments, referring to Figures 3-6 , one end of the main body portion 131 adjacent to the bottom of the box body 10 is a first end, the other end of the main body portion 131 away from the bottom of the box body 10 is a second end, and the distance between the protruding portion 132 and the first end is less than the distance between the protruding portion 132 and the second end.
[0119] Specifically, the first end can be the bottom end of the main body portion 131, and the second end can be the top end of the main body portion 131. The protruding portion 132 is close to the bottom end, i.e., the protruding portion 132 is located at the lower side of the main body portion 131.
[0120] The effect of the present embodiment is that the protruding portion 132 connected with the inner wall of the box body 10 is arranged at the lower side of the main body portion 131, which has better stability when adhered with the inner wall of the box body 10.
[0121] In some embodiments, the thickness of the main body portion 131 is 2.0-3.0 mm.
[0122] Specifically, the connection between the main body portion 131 and the inner wall of the box body 10 is achieved in the form of adhesion, which eliminates the connection structure such as bolts, and the second space 16 can be arranged through the protruding portion 132. Therefore, the thickness of the main body portion 131 can be set thinner under the condition of ensuring the structural strength, the energy density is improved, and the thickness of the main body portion 131 can be 2.0-3.0 mm. Within this range, the strength requirement can be met, and the influence on the energy density is reduced.
[0123] In some embodiments, as Figure 5 and Figure 6 , the second space 16 is located on the side of the protruding portion 132 facing the battery monomer 12, and between the main body portion 131 and the protruding portion 132.
[0124] Specifically, the second space 16 can be a space surrounded by the one side of the protruding portion 132 toward the battery cell 12 and the main body portion 131, and the second space 16 can be formed between the main body portion 131 and the protruding portion 132, such as a gap or a space between the main body portion 131 and the protruding portion 132, which can be used as the second space 16. The present embodiment provides a forming mode of the second space 16, which is simple and reliable in structure.
[0125] In some embodiments, the second space 16 is opened on the protruding portion 132, and the protruding portion 132 is provided with a notch communicating the second space 16 and the first space 15.
[0126] Specifically, the second space 16 can also be directly opened on the protruding portion 132, such as a notch groove structure on the protruding portion 132, and the notch is a notch groove.
[0127] The protruding portion 132 can also form a frame structure due to the opening of the second space 16, and the second space 16 is an inner space of the frame of the protruding portion 132, and is provided with a notch, which communicates with the first space 15 through the notch.
[0128] The present embodiment provides a forming mode of the second space 16, which also achieves the effect of simple and reliable structure.
[0129] The heat-conducting adhesive is arranged between the battery cell 12 and the bottom surface of the box body 10.
[0130] The heat-conducting adhesive can conduct heat, which can enhance the heat dissipation effect of the battery cell 12, and also can play a buffering role to avoid the hard contact between the battery cell 12 and the bottom surface of the box body 10, and achieve a certain protection effect on the battery cell 12.
