[0031] Application Overview

[0032] In recent years, with the rapid development of battery technology, power batteries have been widely used in many fields. For example, in the fields of electric vehicles, power batteries are used as common energy supply equipment. At present, power batteries are usually manufactured in the form of modules or battery packs. In the existing production process, the battery cells are connected to the poles and the busbars by welding so that adjacent battery cells are connected in series or parallel. However, since welding is a non-detachable connection method, the maintenance and replacement costs of battery products connected by welding are relatively high during the later maintenance of the battery, and the busbar is damaged after disassembly, which increases the use cost of the battery product.

[0033] Some embodiments of the battery and electrical equipment in the technical solution of the utility model are provided below.

[0034] In an embodiment of the first aspect of the present utility model, a battery 100 is provided, such as Figure 1 and Figure 2 As shown, the battery 100 includes at least one battery cell 1; each battery cell 1 includes a housing 11, an electrode assembly 12 and a magnet assembly 13. The electrode assembly 12 is the core part of the battery cell 1 and is arranged in the housing 11; the magnet assembly 13 is arranged in the housing 11. When multiple battery cells 1 are assembled, the magnet assembly 13 can generate magnetic force and is suitable for mutual adsorption with the magnet assembly 13 or magnetic parts of other adjacent battery cells 1, for example Figure 3 and Figure 4 The state shown in FIG. 1 is such that the battery cell 1 is electrically connected to other adjacent battery cells 1 .

[0035] It can be understood that each battery cell 1 has a positive electrode and a negative electrode, and two adjacent batteries can be electrically connected through the positive electrode and the negative electrode to form a Figure 3 The series connection shown in the figure can also be formed in parallel by electrically connecting the positive electrodes to the positive electrodes and the negative electrodes to the negative electrodes. In practical applications, the magnet assembly 13 can be set at a corresponding position according to the different series or parallel assembly forms of the battery cells 1 to make the connection between adjacent battery cells 1 more secure.

[0036] It should be noted that, according to specific assembly requirements, the magnet assembly 13 may include one or more magnets to facilitate adsorption with the battery cell 1. Since the magnet has an N pole and an S pole with opposite polarities, during assembly, the N pole of one magnet may be arranged opposite to the S pole of another magnet as required, so that the magnetic force may be used to produce a mutual adsorption effect.

[0037] The battery 100 in this embodiment improves the connection method between battery cells 1, and adopts magnetic adsorption instead of traditional welding. Multiple battery cells 1 are connected in series or in parallel through the magnet assembly 13. There is no need for welding operation, which simplifies the assembly operation and is beneficial to improving production efficiency. At the same time, the connection through magnetic adsorption is a detachable connection method, which is also convenient for later maintenance and disassembly and replacement, and can greatly reduce maintenance costs.

[0038] It should be emphasized that the battery 100 in this embodiment includes but is not limited to a battery cell form, a module form or a battery pack form. Figure 1 The cylindrical battery shown in the figure may also adopt battery structures of other shapes. The magnetic attraction method in this embodiment is not only applicable to the series or parallel connection between multiple battery cells, but also applicable to the contact connection between the battery cells and the busbar of the battery pack.

[0039] In a further embodiment of the present invention, Figure 2 , Figure 4 As shown, the electrode assembly 12 includes a first electrode and a second electrode with opposite polarities, wherein one is a positive electrode and the other is a negative electrode. The magnet assembly 13 includes at least one first magnet 131, and the first magnet 131 is arranged corresponding to the first electrode. When the first electrode of the battery cell 1 is electrically connected to the first electrode or the second electrode of another adjacent battery cell 1, the first magnet 131 can be adsorbed by the magnet assembly 13 or the magnetic member of the adjacent battery cell 1 through the action of magnetic force, so that the battery cells 1 are firmly connected. For example Figure 2 In the example, the first electrode is located at one end of the battery cell 1 in the axial direction, and the first magnet 131 is located in the housing 11 near the first electrode; when two adjacent battery cells 1 are connected in series, as shown in FIG. Figure 4In the example, the first electrode of one battery cell 1 is arranged corresponding to the second electrode of another battery cell 1, and accordingly, the first magnet 131 of one battery cell 1 is attracted to the magnet assembly 13 or magnetic member opposite to the second electrode of the other battery cell 1 through magnetic force, so that the two battery cells 1 are in a contact electrical connection state.

[0040] Furthermore, in a specific implementation, Figure 2 and Figure 5 As shown, in the first direction (i.e. Figure 2 In the axial direction of the battery cell 1 in the middle), a first pole 121 is provided at one end of the shell 11, and a pole hole 113 is provided at a position corresponding to the first pole 121 on the shell 11. One end of the first pole 121 extends into the shell 11 and is electrically connected to the first electrode of the electrode assembly 12. The other end of the first pole 121 is located outside the shell 11 to facilitate electrical connection with the adjacent battery cell 1. Correspondingly, the first magnet 131 is disposed at one end of the shell 11 close to the first pole 121, for example Figure 2 In the example in FIG. 1 , the first magnet 131 is arranged around the first pole 121 so that the end faces of the housing 11 around the first pole 121 are all opposite to the first magnet 131, thereby increasing the magnetic coverage of the first magnet 131. When connected in series with other battery cells 1, such as Figure 3 and Figure 4 In the example, no matter at which angle the battery cell 1 is in the circumferential direction, the first magnet 131 can form an adsorption connection between adjacent battery cells 1 through magnetic force, and the assembly operation is more convenient.

[0041] In a further embodiment of the present invention, Figure 6 , Figure 7 and Figure 8 As shown, the battery 100 further includes a first adapter 21 and a first magnetic member 31, and accordingly, the number of battery cells 1 is multiple. In the first direction, the first magnet 131 of each battery cell 1 is disposed at one end in the housing 11 and is electrically connected to the first pole 121 on the housing 11; the third magnet of each battery cell 1 is disposed at the other end away from the first magnet 131 in the first direction. The first magnetic member 31 is disposed correspondingly to the first adapter 21, the first pole 121 of each battery cell 1 is electrically connected to the first adapter 21, and the first magnet 131 of each battery cell 1 is disposed opposite to the first magnetic member 31, and each battery cell 1 is firmly adsorbed and connected to the first adapter 21 through magnetic force.

[0042] The number of battery cells 1 can be set according to the power demand, and the relative position between the battery cells 1 and the first adapter 21 can be set according to the specific assembly requirements. For example, Figure 7As shown in the figure, a row of battery cells 1 is arranged on both sides of the first adapter 21, but of course, one or more rows of battery cells 1 can be arranged on only one side of the first adapter 21, or other arrangements can be adopted. In this embodiment, the battery 100 can be formed into a module.

[0043] Furthermore, if Figures 6 to 8 As shown, the shell 11 of each battery cell 1 is electrically connected to the second electrode. Accordingly, the magnet assembly 13 of each battery cell 1 also includes a second magnet 132, and the second magnet 132 is located in the shell 11 at a position corresponding to the side wall. The battery 100 also includes a correspondingly arranged second adapter 22 and a second magnetic member 32; the second adapter 22 is arranged on the side of the plurality of battery cells 1, the shell 11 of each battery cell 1 is electrically connected to the second adapter 22, and the second magnet 132 of each battery cell 1 generates a magnetic adsorption effect with the second magnetic member 32, so that the shell 11 of the battery cell 1 and the second adapter 22 form a firm electrical connection state. Through the arrangement in this embodiment, multiple battery cells 1 can be formed into a parallel module form, so that the first electrode of each battery cell 1 is electrically connected through the first adapter 21, and at the same time, the second electrode of each battery cell 1 is electrically connected through the second adapter 22.

[0044] Furthermore, in a specific implementation, Figures 6 to 8 As shown, the first adapter 21 is provided with a slot structure 211, and accordingly, the first magnetic member 31 adopts a strip plate structure, and the first magnetic member 31 is inserted into the slot structure 211 of the first adapter 21 to achieve an assembly connection between the two. Correspondingly, the battery cell 1, the second adapter 22 and the second magnetic member 32 are all arranged on the side of the first adapter 21, for example Figure 7 The first adapter 21 shown in the figure is connected to both sides of the first adapter 21, wherein the first pole 121 of each battery cell 1 is electrically connected to the outer side wall of the slot structure 211 to achieve the connection between the first electrodes of multiple battery cells 1. Preferably, the outer side wall of the slot structure 211 is provided with multiple contacts 212 for contacting the first pole 121 of the battery cell 1; the end of the slot structure 211 is also provided with a secondary connector 213, such as Figure 8 The columnar structure shown in the figure is used as the pole of the entire battery through the auxiliary connecting piece 213, which is convenient for connection.

[0045] Furthermore, if Figures 6 to 8As shown, the second magnetic member 32 is provided with a plurality of receiving grooves 321, and the size of the receiving grooves 321 is adapted to the battery cell 1; in the arrangement of the second adapter 22, one side of the receiving groove 321 is provided on the second magnetic member 32, and is arranged corresponding to the receiving groove 321; wherein, the second adapter 22 includes a plurality of elastic snap-in plates 221, and both sides of each receiving groove 321 are provided with elastic snap-in plates 221. When the battery cell 1 is placed in the receiving groove 321, the elastic snap-in plates 221 on both sides of the receiving groove 321 can form a snap fit with the battery cell 1, and at the same time, the housing 11 of the battery cell 1 is in contact with the second adapter 22 to form an electrical connection. Correspondingly, the second magnetic member 32 is mutually attracted to the second magnet 132 of each battery cell 1 through the action of magnetic force, so that the battery cell 1 and the second adapter plate form a firm electrical connection state.

[0046] In this embodiment, the elastic clamping piece 221 can be used to form a contact-type elastic electrical connection between the battery cells, and quick disassembly and assembly can be achieved during later maintenance, and any battery cell can be disassembled separately, making the operation more convenient and more efficient. It can be understood that the elastic clamping piece 221 may weaken in elastic force during long-term use, resulting in increased contact resistance. The fourth magnetic body 32 can ensure that the battery cell 1 and the second adapter 22 remain tightly fitted when the elastic force of the elastic clamping piece 221 weakens.

[0047] In practical applications, the first adapter 21 and the second adapter 22 are separated from each other to prevent short circuit. Figure 8 In the example, a second magnetic member 32 is provided on both sides of the first adapter 21, and the end of each receiving groove 321 facing the first adapter 21 is a through structure. When the battery cell 1 is placed in the receiving groove 321, the first pole 121 can directly contact the first adapter 21 and form an electrical connection. The second adapter 22 can be used as follows Figure 8 The frame structure shown in the figure is convenient for assembly with the second magnetic member 32.

[0048] In addition, according to assembly requirements, the battery 100 may also include Figure 8 The support base 33 shown in the figure has an assembly groove 331 on one side of the support base 33. The second magnetic member 32, the second adapter 22, the battery cell 1, the first adapter 21, and the first magnetic member 31 are all arranged in the assembly groove 331 of the support base 33 for fixing and assembling. Of course, a box structure or other structure can also be used to replace the support base 33 according to different specific assembly requirements, which will not be repeated here.

[0049] In a further embodiment of the present invention, Fig. 9 and Fig.10As shown, the housing 11 of the battery cell 1 is electrically connected to the first electrode of the electrode assembly 12. Accordingly, the first magnet 131 is disposed in the housing 11 near the end of the housing 11, as shown in FIG. Fig. 9 In the example of FIG. 1 , the first magnet 131 is disposed at an end away from the first pole 121 in the first direction, or as Fig.10 In the example, the first magnet 131 is disposed in the housing 11 near the side wall of the housing 11. With the arrangement in this embodiment, when the battery cell 1 is electrically connected to the adjacent battery cell 1 through the housing 11, the corresponding first magnet 131 and the magnet assembly 13 or magnetic member of the adjacent battery cell 1 can generate a magnetic force of mutual attraction, so that the battery cell 1 can maintain a stable connection state.

[0050] In a further embodiment of the present invention, Figure 2 and Figure 5 As shown, the magnet assembly 13 also includes at least one second magnet 132; the second magnet 132 is arranged corresponding to the second electrode of the electrode assembly 12, and when the second electrode forms an electrical connection with the first electrode or the second electrode of the adjacent battery cell 1, the second magnet 132 can produce a mutual adsorption effect with the magnet assembly 13 or the magnetic member of the adjacent battery cell 1, so that the two adjacent battery cells 1 maintain an adsorption connection state. Figure 4 In the example, the first electrode and the second electrode of the battery cell 1 are respectively located at the two ends in the first direction, and accordingly, the first magnet 131 of the magnet assembly 13 is located at one end of the shell 11 close to the first electrode, and the second magnet 132 is located at one end of the shell 11 close to the second electrode; when two adjacent battery cells 1 form a series state, the second electrode and the second magnet 132 of the battery cell 1 on the left are located near the right end, and the first electrode and the first magnet 131 of the battery cell 1 on the right are located near the left end, and the end surface of the shell 11 of the left battery cell 1 contacts the first pole 121 of the right battery cell 1 and forms an electrical connection, and correspondingly, the second magnet 132 of the left battery cell 1 and the first magnet 131 of the right battery cell 1 are mutually adsorbed by magnetic force, so that the two battery cells 1 form a firmly adsorbed connection state.

[0051] Preferably, if Figure 5 In the example in FIG. 1 , the first magnet 131 and the second magnet 132 both adopt the structure of annular magnetic sheets to match the structure of the cylindrical battery cell 1 .

[0052] by Figure 5Taking the battery cell 1 shown in the figure as an example, the first electrode of the electrode assembly 12 is a positive electrode, the second electrode is a negative electrode, and the first electrode is electrically connected to the first pole 121, and the second electrode is connected to the shell 11; the first magnet 131 and the second magnet 132 are both annular magnetic sheet structures, the first magnet 131 is arranged corresponding to the first pole 121, and the second magnet 132 is arranged corresponding to the end cover 112 of the shell 11 away from the first pole 121. In order to meet the manufacturing and assembly requirements, the battery cell 1 may also include a welding ring 141, an upper plastic 142, a sealing ring 143, a lower plastic 144, a positive bus bar 145, a negative bus bar 146, and a sealing nail 147 to assemble and form a complete battery cell 1.

[0053] In this embodiment, the arrangement of the first magnet 131 and the second magnet 132 is suitable for adapting to the assembly form of connecting multiple battery cells 1 in series in sequence, so that the battery forms a module form. Among them, the structure of each battery cell 1 is the same, and the corresponding number of battery cells 1 can be set according to the assembly needs to meet the power supply requirements. In addition, the first magnet 131 and the second magnet 132 can also have an insulating effect, such as a ferrite magnet, a rubber magnet, etc. When the battery has thermal runaway, the lower plastic will melt and lose its insulating effect. At this time, the first magnet 131 and the second magnet 132 can effectively isolate the positive pole from the negative pole to avoid short circuit.

[0054] Furthermore, in a specific implementation, Fig. 9 As shown, in the first direction of the battery cell 1, a second pole 122 is provided at one end of the shell 11, and a pole hole 113 is opened at a position corresponding to the second pole 122 on the shell 11, one end of the second pole 122 extends into the shell 11 and is electrically connected to the second electrode of the electrode assembly 12, and the other end of the second pole 122 extends out of the shell 11 to facilitate electrical connection with the adjacent battery cell 1; accordingly, the second magnet 132 is arranged in the shell 11 at one end close to the second pole 122, so as to generate magnetic adsorption with the first magnet 131 or magnetic part of the adjacent battery cell 1.

[0055] Furthermore, in another specific implementation, as Figure 2 As shown, the housing 11 is electrically connected to the second electrode of the electrode assembly 12. Accordingly, the second magnet 132 is disposed in the housing 11 near the end of the housing 11. When two adjacent battery cells 1 are connected in series, as shown in FIG. Figure 4 In the example, the second magnet 132 and the first magnet 131 of the adjacent battery cell 1 are attracted to each other by magnetic force, so that the two battery cells 1 are adsorbed and connected to each other, and a firm connection state is maintained.

[0056] Furthermore, in another specific implementation, Figure 6As shown, the shell 11 is electrically connected to the second electrode, and accordingly, the second magnet 132 is arranged in the shell 11 near the side wall; when the side wall of the shell 11 is electrically connected to the adjacent battery cell 1, the second magnet 132 can be adsorbed with the corresponding magnet assembly 13 or magnetic part to form a firm connection between the battery cells 1.

[0057] by Figure 6 Taking the battery cell 1 shown in the figure as an example, the first electrode of the electrode assembly 12 is a positive electrode, the second electrode is a negative electrode, and the first electrode is electrically connected to the first pole 121, and the second electrode is connected to the housing 11; the first magnet 131 is a circular magnetic sheet, and is arranged corresponding to the first pole 121; the second magnet 132 is a cylindrical structure, and is arranged corresponding to the side shell 111 of the housing 11. In order to meet the manufacturing and assembly requirements, the battery cell 1 may also include a welding ring 141, an upper plastic 142, a sealing ring 143, a lower plastic 144, a positive bus bar 145, a negative bus bar 146, and a sealing nail 147 to assemble and form a complete battery cell 1.

[0058] It should be noted that several different arrangements of the first magnet 131 and the second magnet 132 are shown above, and in practical applications, a matching arrangement can be selected according to the specific assembly form between the battery cells 1. In addition, the first magnet 131 and the second magnet 132 can also have an insulating effect. When the battery has thermal runaway, the lower plastic will melt and lose its insulating effect. At this time, the first magnet 131 and the second magnet 132 can effectively isolate the positive electrode from the negative electrode to avoid short circuit.
