Description

Technical Field

[0001] The present application relates to the technical field of batteries, and relates to a battery and an electrical device. Background Art

[0002] With the rapid development of new energy, batteries are used more and more widely. A battery includes a box body and battery cells disposed in the box body. A connector is disposed on the box body, and the connector is used for electrically connecting with the battery cells. During the assembly process of the connector during the manufacturing process of the battery, there is a problem of incorrect installation. Summary of the Utility Model

[0003] In view of the above problems, the present application provides a battery and an electrical device to effectively avoid the problem of incorrect installation of the connector.

[0004] In a first aspect of the present application, a battery is provided, including battery cells, a box body and a panel. The box body has a receiving cavity, and the battery cells are disposed in the receiving cavity. The panel is disposed on the box wall of the box body, and the panel includes a panel main body, a connector mounting portion disposed on the panel main body, and an electrical connector. The connector mounting portion is disposed on the panel main body. The electrical connector includes a terminal electrically connected to the battery cells, and the terminal is disposed in the mounting cavity of the connector mounting portion. Wherein, the panel further includes a connector protection cover covering the connector mounting portion, and the connector protection cover includes an anti-fooling structure configured to abut against the end face of the terminal to prevent incorrect installation.

[0005] The connector protection cover of the technical solution of the embodiment of the present application includes an anti-fooling structure. In this way, when the electrical connector is correctly installed, the end face of the terminal can abut against the anti-fooling structure, and when the electrical connector is incorrectly installed, the anti-fooling structure interferes with the end face of the terminal and cannot be installed, realizing the anti-fooling function, and thus effectively avoiding the problem of incorrect installation of the electrical connector.

[0006] In some embodiments, the connector mounting portion has an opening communicating with the mounting cavity, and the connector protection cover further includes a cover body covering the opening, and the anti-fooling structure is disposed on the inner side of the cover body. The technical solution of the embodiment of the present application utilizes the structure of the connector protection cover that already exists in the related art, and only needs to add an anti-fooling structure on the inner side of the cover body of the connector protection cover. Therefore, the structure is simple and the applicable range is wider.

[0007] In some embodiments, the anti-fooling structure includes a cylinder extending in the circumferential direction of the cover body. The cylinder extends in the entire circumferential direction of the cover body. In this way, when installing the cover body, there is no need to pay attention to the position of the following cylinder. As long as the cover body is covered on the opening, any position of the cylinder can realize the anti-fooling function, thereby reducing the debugging time of the installer and improving the assembly efficiency.

[0008] In some embodiments, the cylinder body includes a circular cylinder body. Setting the cylinder body as a circular cylinder body can prevent incorrect assembly while occupying a relatively small area, thereby improving the structural compactness of the panel in the embodiments of the present application.

[0009] In some embodiments, the connector protection cover is detachably connected to the connector mounting portion. Before installing the electrical connector, the connector protection cover is pre-mounted on the connector mounting portion so that the anti-incorrect-assembly structure abuts against the end face of the terminal; after installing the electrical connector, the connector protection cover is removed to fix the terminal through the opening by means of a connecting member. The technical solution of the embodiments of the present application sets the connector protection cover to be detachably connected, so that the connector protection cover forms different functions at different stages of installing the electrical connector. Before installing the electrical connector, the connector protection cover is pre-mounted in place, so that the problem of incorrect installation of the electrical connector can be avoided through the anti-incorrect-assembly structure. After the electrical connector is installed in place, the connector protection cover plays a role in protecting the terminal.

[0010] In some embodiments, the electrical connector includes a wire. The first end of the terminal is electrically connected to the wire. The second end of the terminal has an end face, and the end face includes an inclined surface and an electrical connection end. The inclined surface is inclined with respect to the axis of the terminal and has a proximal portion closer to the wire and a distal portion farther from the wire, wherein the electrical connection end is provided at the distal portion. By providing the electrical connection end at the distal portion of the inclined surface, the electrical connector in the embodiments of the present application increases the contact area and improves the reliability of the electrical connection.

[0011] In some embodiments, the installation cavity of the connector mounting portion includes a first cavity extending in a first direction and a second cavity connected to one end of the first cavity and extending in a second direction. The first direction and the second direction are perpendicular to each other. The first cavity and the second cavity communicate with each other. The second cavity has an opening, and the opening is located at the axial end of the second cavity. The connector protection cover is provided at the opening. Setting the connector protection cover at the opening at the axial end of the second cavity makes it easier to form a seal between the cover body and the opening compared with directly providing an opening on the circumferential wall of the first cavity. Therefore, it is more conducive to forming a sealed protection for the internal terminals.

[0012] In some embodiments, the connector protection cover is coaxially arranged with the second cavity. Setting the connector protection cover to be coaxially arranged with the second cavity makes the cylinder body extending along the circumferential direction of the connector protection cover also coaxially arranged with the second cavity, thereby avoiding the interference problem between the cylinder body and the second cavity.

[0013] In some embodiments, the panel includes two electrical connectors disposed on the panel body and two connector mounting portions correspondingly arranged with the two electrical connectors. The two electrical connectors include a positive high-voltage connector and a negative high-voltage connector, and the two electrical connectors are correspondingly installed in the two connector mounting portions. The two connector mounting portions are respectively disposed at two ends of the panel. By disposing the two connector mounting portions at two ends in the length direction of the panel in the embodiments of the present application, the positive high-voltage connector and the negative high-voltage connector are respectively located at two ends in the length direction of the panel, so that the distance between the positive and negative poles on the box body is as far as possible, thereby improving the safety of the battery.

[0014] In a second aspect of the present application, an electrical device is provided, including the above battery, and the battery is used to provide electrical energy.

The new energy vehicle can be a pure electric vehicle, a hybrid vehicle, or an extended-range vehicle.Figure 1 A vehicle 2000 using a battery 1000 as a power source is shown.

[0041] Reference Figure 2 , the battery 1000 is disposed inside the vehicle 2000 and includes at least one battery module. A drive motor is disposed inside the vehicle 2000, and the drive motor is electrically connected to the battery 1000. The battery 1000 provides electrical energy for the drive motor, and the drive motor is connected to the wheels through a transmission mechanism to drive the vehicle forward. Specifically, the battery 1000 can be horizontally disposed at the bottom of the vehicle 2000.

[0042] The battery 1000 of the embodiment of the present application includes a plurality of battery cells 100. Specifically, in this embodiment, as Figure 2 shown, the battery 1000 of this embodiment includes a plurality of battery cells 100 and a box body 200 for accommodating the plurality of battery cells 100. The box body 200 has an accommodation cavity, and the plurality of battery cells 100 are arranged in the accommodation cavity. Specifically, the box body 200 of this embodiment is a box-shaped box body and includes an upper box body 210 and a lower box body 220 for accommodating the battery cells 100. The upper box body 210 and the lower box body 220 are covered to form the accommodation cavity. In embodiments not shown in other drawings, the box body can also be other shapes such as a frame-shaped box body or a disk-shaped box body. Moreover, the shapes of the upper box body 210 and the lower box body 220 can also be different, which is not limited herein.

[0043] The battery cell 100 can include a lithium-ion secondary battery, a lithium-ion primary battery, a lithium-sulfur battery, a sodium-lithium-ion battery, a sodium-ion battery, a magnesium-ion battery, etc. The embodiment of the present application does not limit this. The plurality of battery cells 100 are electrically connected through connection tabs. The plurality of battery cells 100 can be connected in series, in parallel, or in a series-parallel connection under the connection of the connection tabs.

[0044] The battery cell 100 includes a housing, an electrode assembly, and other functional components. The inner cavity of the housing is used to accommodate the electrode assembly. The housing includes a housing body and an end cap covering the opening of the housing body to isolate the internal environment of the battery cell from the external environment. The housing body is a component for cooperating with the end cap to form the internal environment of the battery cell. Among them, the formed internal environment can be used to accommodate the electrode assembly, the electrolyte, and other components. The housing body and the end cap can be independent components. An opening can be provided on the housing body, and the end cap is covered at the opening to form the internal environment of the battery cell. The material of the housing body can be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc. The embodiment of the present application does not make special restrictions on this.

[0045] The electrode assembly is a component in the battery cell where electrochemical reactions occur. The housing can contain one or more electrode assemblies. The electrode assembly is mainly formed by winding or laminating a positive electrode sheet and a negative electrode sheet. During the charging and discharging process of the battery, the positive active material and the negative active material react with the electrolyte, and the tab connects to the terminal to form an electric current loop. The electrode assembly can be a wound structure or a stacked structure, and the embodiments of the present application are not limited to this.

[0046] For the electrical energy output of the battery 1000 to supply power to the electrical device or to charge the battery 1000, the battery 1000 further includes a panel 1 provided on the box body 200. An electrical connector is provided on the panel 1, and the electrical connector is electrically connected to the battery cell inside the box body 200. A connector mounting portion is provided on the panel 1 for mounting the electrical connector. The terminal 141 of the electrical connector 14 is disposed in the mounting cavity of the connector mounting portion and is electrically connected to the battery cell. The first end of the terminal 141 is connected to a wire, and the second end of the terminal 141 is electrically connected to the battery cell. Since the second end of the terminal 141 has an asymmetric structure, there is a problem of being installed reversely during the assembly process. As Figure 6 shown, the second end of the terminal 141 has an inclined surface, and an extension end is further provided at the lower end of the inclined surface. The extension end realizes the electrical connection with the battery cell. Therefore, if the terminal 141 is installed reversely, the extension end will be located on the upper side, so that an effective contact area cannot be formed with the battery cell and the electrical connection cannot be achieved. Therefore, how to effectively avoid the reverse installation of the connector is a technical problem to be solved urgently.

[0047] To solve this problem, the present application proposes a battery. By providing an anti-fooling structure on the connector protection cover 13, when assembling the electrical connector, the connector protection cover 13 can be pre-installed first. If the electrical connector is installed correctly, the anti-fooling structure abuts against the electrical connector and can be installed in place; if the electrical connector is installed reversely, due to the existence of the anti-fooling structure, the electrical connector cannot be installed in place, and the installer can be prompted to re-assemble, thereby avoiding reverse installation.

[0048] Next, refer to Figures 2 to 8 to describe in detail the structure of the battery according to some embodiments of the present application.

[0049] The battery 1000 provided by some embodiments of the present application includes a battery cell 100, a box body 200, and a panel 1. The box body 200 has a receiving cavity. And the battery cell 100 is disposed in the receiving cavity. The panel 1 is disposed on the box wall of the box body 200. And the panel 1 includes a panel main body 11, a connector mounting portion 12 provided on the panel main body 11, and an electrical connector 14. The connector mounting portion 12 is provided on the panel main body 11. The electrical connector 14 includes a terminal 141 electrically connected to the battery cell 100. The terminal 141 is disposed in the mounting cavity of the connector mounting portion 12.

[0050] Among them, the panel 1 further includes a connector protection cover 13 covering the connector installation portion 12. The connector protection cover 13 includes an anti-fooling structure. The anti-fooling structure is configured to abut against the end face of the terminal 141 to prevent misconnection.

[0051] Reference Figure 3 , in some embodiments, the panel 1 includes a panel main body 11 and a connector installation portion 12 provided on the panel main body 11. Specifically, in the Figure 3 illustrated embodiment, the panel 1 includes two connector installation portions 12, and the two connector installation portions 12 are respectively provided at both ends of the panel main body 11 and are respectively used for installing a positive high-voltage connector and a negative high-voltage connector. Specifically, the connector installation portion 12 is provided on the outer surface of the panel main body 11. The inner surface of the panel main body 11 is the side surface close to the box body 200, and the outer surface is the other side surface away from the box body 200. When manufacturing the box body 200, a panel installation window is formed on the box body 200, and the panel 1 is installed at the panel installation window by connection means such as welding, snap connection or bonding. Or the panel 1 can also be installed on the box body 200 by means of threaded connectors or riveting parts.

[0052] Reference Figures 4 to 8 , especially reference Figure 6 , the electrical connector 14 includes a terminal 141 and a wire (not shown in the figure). The first end of the wire is connected to the terminal 141, and the second end of the wire extends out of the outside of the connector installation portion 12 to be electrically connected to the outside. The terminal 141 is installed in the installation cavity of the connector installation portion 12 and is electrically connected to the battery cell 100. Specifically, as Figure 6 shown, the first end of the terminal 141 is electrically connected to the wire, the second end of the terminal 141 is electrically connected to the battery cell 100, and the second end of the terminal 141 is a non-planar structure, which includes an inclined surface 1411 and an electrical connection end 1412. The inclined surface 1411 is inclined with respect to the axis of the terminal 141, so that the second end of the terminal 141 has a proximal portion closer to the wire and a distal portion farther from the wire. Among them, the electrical connection end 1412 is provided at the distal portion. That is, the electrical connection end 1412 extends outward along the distal portion. When the terminal 141 is electrically connected to the battery cell 100, the part that realizes the electrical connection is exactly the electrical connection end 1412. Therefore, if the electrical connector 14 is installed in the reverse direction, then reference Figure 6 , it means that the electrical connection end 1412 is installed on the Figure 6 upper side in, and the close part is located on the lower side, and the size of the close part is very small, so effective electrical contact cannot be achieved, and therefore effective electrical connection cannot be completed.

[0053] Reference Figures 4 to 6, the panel 1 of the embodiment of the present application further includes a connector protection cover 13. The connector protection cover 13 covers the opening of the connector installation part 12 to protect the terminal 141. Moreover, when installing the electrical connector 14, the terminal 141 is inserted into the connector installation part 12 from the port 12a of the connector installation part 12, and after insertion, a connecting piece is also required to connect and fix the terminal 141. Therefore, the connector installation part 12 is also provided with an opening 12b. In this way, the installer can enter the interior from the opening 12b to connect and fix the terminal 141. Then, after installation, the connector protection cover 13 is covered on the opening to protect the terminal.

[0054] The technical solution of the embodiment of the present application sets an anti-fooling structure on the cover body of the connector protection cover 13. In this way, before the installer places the electrical connector into the installation cavity of the connector installation part 12, the connector protection cover 13 is pre-installed at the opening first, so that the anti-fooling structure of the connector protection cover can achieve the anti-fooling function. Then, the connector protection cover is removed, and the terminal is connected by a connecting piece through the opening and into the interior of the installation cavity. Finally, the connector protection cover is covered again to protect the terminal.

[0055] The connector protection cover 13 of the technical solution of the embodiment of the present application includes an anti-fooling structure. In this way, when the electrical connector is installed correctly, the end face of the terminal 141 can abut against the anti-fooling structure, while when the electrical connector is installed reversely, the anti-fooling structure interferes with the end face of the terminal 141 and cannot be installed, realizing the anti-fooling function, and effectively avoiding the problem of reverse installation of the electrical connector.

[0056] In some embodiments, referring to Figure 6 , the connector installation part 12 has an opening 12b communicating with the installation cavity. The connector protection cover 13 further includes a cover body 131 covering the opening 12b, and the anti-fooling structure is arranged on the inner side of the cover body 131. The technical solution of the embodiment of the present application utilizes the structure of the connector protection cover 13 that already exists in the related art. As long as an anti-fooling structure is added to the inner side of the cover body 131 of the connector protection cover 13, the structure is simple and the applicable range is wider.

[0057] In some embodiments, referring to Figure 4 and Figure 6 , the anti-fooling structure includes a cylinder 132 extending in the circumferential direction of the cover body 131. The cylinder 132 extends in the entire circumferential direction of the cover body 131. In this way, when installing the cover body 131, there is no need to pay attention to the position of the following cylinder 132. As long as the cover body 131 is covered on the opening, any position of the cylinder 132 can achieve the anti-fooling function, thereby reducing the debugging time of the installer and improving the assembly efficiency.

[0058] In some embodiments not shown in other drawings, an anti-fooling structure, such as an anti-fooling wall, may also be provided only at one end of the cover body 131 close to the wire. In this way, interference with the terminal can be formed during reverse installation to effectively avoid the problem of incorrect installation of the electrical connector.

[0059] In some embodiments, the cylinder 132 includes a circular cylinder. The cylinder 132 is set as a circular cylinder, so that the area occupied is relatively small while anti-fooling, thereby improving the structural compactness of the panel of the embodiment of the present application.

[0060] In some embodiments, the connector protection cover 13 is detachably connected to the connector mounting portion. Before installing the electrical connector 14, the connector protection cover 13 is pre-mounted on the connector mounting portion so that the anti-fooling structure abuts against the end face of the terminal 141. After installing the electrical connector 14, the connector protection cover 13 is removed to fix the terminal 141 through the opening by means of a connecting member.

[0061] Before the installer places the terminal of the electrical connector 14 into the installation cavity of the connector mounting portion 12, the connector protection cover 13 is pre-mounted at the opening first. In this way, the anti-fooling structure of the connector protection cover can achieve the anti-fooling function. Then, the connector protection cover is removed, and the connecting member is used to connect the terminal through the opening into the interior of the installation cavity. Finally, the connector protection cover is covered to protect the terminal. It can be seen that the technical solution of the embodiment of the present application sets the connector protection cover 13 to be detachably connected, so that the connector protection cover 13 forms different functions at different stages of installing the electrical connector. Before installing the electrical connector, the connector protection cover 13 is pre-mounted in place, so that the problem of incorrect installation of the electrical connector can be avoided through the anti-fooling structure. After the electrical connector is installed in place, the connector protection cover 13 plays a role in protecting the terminal.

[0062] In some embodiments, the electrical connector 14 includes a wire (not shown in the figure). The first end of the terminal 141 is electrically connected to the wire. The second end of the terminal 141 includes an end face. The end face includes an inclined surface 1411 and an electrical connection end 1412. The inclined surface 1411 is inclined with respect to the axis of the terminal 141, and the inclined surface 1411 has a proximal portion closer to the wire and a distal portion farther from the wire, wherein the electrical connection end 1412 is provided at the distal portion.

[0063] The electrical connector 14 of the embodiment of the present application increases the contact area and improves the reliability of electrical connection by providing the electrical connection end 1412 at the distal portion of the inclined surface 1411.

[0064] Reference Figure 3, in some embodiments, the installation cavity of the connector installation part 12 includes a first cavity 121 extending along a first direction X and a second cavity 122 connected to one end of the first cavity 121 and extending along a second direction Y. The first direction X and the second direction Y are perpendicular to each other. The first cavity 121 and the second cavity 122 are in communication, the second cavity 122 has an opening 12b, and the opening 12b is located at the axial end of the second cavity 122. The connector protection cover 13 is provided at the opening 12b.

[0065] In the connector installation part 12 of the embodiment of the present application, by providing the first cavity 121 and the second cavity 122 that are perpendicular to each other, the electrical connection end 1412 of the terminal 141 extends into the second cavity 122. In this way, the connector protection cover 13 is provided at the opening at the axial end of the second cavity 122. Compared with directly providing an opening on the circumferential wall of the first cavity 121, when the opening is provided at the axial end, the openings are substantially in the same plane. Therefore, it is easier to form a seal between the cover body 131 and the opening, and thus it is more conducive to forming a sealed protection for the internal terminals.

[0066] In some embodiments, the connector protection cover 13 is coaxially arranged with the second cavity 122.

[0067] The connector protection cover 13 is arranged to be coaxially arranged with the second cavity 122. In this way, the cylinder body 132 extending along the circumferential direction of the connector protection cover 13 is also coaxially arranged with the second cavity 122, thereby avoiding the interference problem between the cylinder body 132 and the second cavity 122.

[0068] In some embodiments, the panel 1 includes two electrical connectors 14 provided on the panel body 11 and two connector installation parts 12 corresponding to the two electrical connectors 14. The two electrical connectors include a positive high-voltage connector and a negative high-voltage connector. And the two electrical connectors are correspondingly installed in the two connector installation parts 12. The two connector installation parts 12 are respectively arranged at both ends in the length direction of the panel 1.

[0069] In the panel 1 of the embodiment of the present application, by respectively arranging the two connector installation parts 12 at both ends in the length direction of the panel 1, the positive high-voltage connector and the negative high-voltage connector are respectively located at both ends in the length direction of the panel 1, so that the distance between the positive and negative poles on the box body 200 is as far as possible, thereby improving the safety of the battery.

[0070] The length direction of the panel 1 is parallel to the first direction X.

[0071] Some other embodiments of the present application further provide an electrical device, including the above battery, and the battery is used to provide electrical energy.

[0072] Next, according to Figures 1 to 8 A detailed description will be given of the structure of the battery in a specific embodiment of the present application.

[0073] The battery 1000 of this embodiment includes a box body 200, battery cells 100, and a panel 1 disposed on the box body 200.

[0074] As Figures 3 to 8 shown, the panel 1 includes a panel main body 11, a connector mounting portion 12 disposed on the panel main body 11, a connector protection cover 13, and an electrical connector 14.

[0075] Among them, two connector mounting portions 12 are respectively disposed at both ends in the length direction of the panel main body 11, and an electrical connector 14 is disposed in each connector mounting portion 12. The electrical connector 14 is a high-voltage connector. Correspondingly, a connector protection cover 13 is also disposed on each connector mounting portion 12.

[0076] The structure of one of the connector mounting portions 12 will be described in detail below.

[0077] As Figure 3 and Figure 6 shown, the connector mounting portion 12 includes a first cavity 121 and a second cavity 122 that are cross-set. The second cavity 122 is connected to the end of the first cavity 121 and is internally connected. Both the first cavity 121 and the second cavity 122 are cylindrical cavities. Among them, one end of the first cavity 121 forms a port 12a, and one end of the second cavity 122 forms an opening 12b. The opening 12b is used to mount the connector protection cover 13.

[0078] The electrical connector 14 includes a terminal 141 electrically connected to the battery cell and a wire (not shown in the figure).

[0079] Before installing the electrical connector 14, first pre-install the connector protection cover 13 at the opening 12b, and then insert the electrical connector 14 into the installation cavity from the port 12a, and make the electrical connection end 1412 of the terminal 141 extend into the second cavity 122. At this time, the cylinder body 132 of the connector protection cover 13 forms an anti-fooling structure. When the electrical connector 14 is correctly installed, the end face of the terminal 141 of the electrical connector 14 can abut against the lower end of the cylinder body 132; when the electrical connector 14 is installed in the reverse direction, the end face of the terminal 141 of the electrical connector 14 interferes with the lower end of the cylinder body 132 and cannot be installed.

[0080] When the electrical connector 14 of this embodiment is inserted in the reverse direction, it interferes with the cylinder body 132 (anti-fooling structure), so the electrical connector cannot be normally assembled; only when the electrical connector 14 is inserted in the correct direction can it be normally installed, thereby realizing the anti-fooling function of assembly.

[0081] Although the present application has been described with reference to the preferred embodiments, various modifications can be made thereto and components thereof can be replaced with equivalents without departing from the scope of the present application. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any manner. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
