Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, specifically to a battery cell charging and discharging fixture. Background Technology

[0002] In today's era of rapid development of new energy technologies, battery cells are one of the most important materials for every new energy company. However, due to a series of issues such as environment and storage time, battery cells will experience varying degrees of self-discharge. When the battery cell fails to reach the specified capacity, it needs to be recharged offline.

[0003] In current technology, the charging operation of battery cells mainly involves using two wires, positive and negative, from an external charging / discharging device. A worker then connects these two wires to the positive and negative terminals of the battery cell, respectively, to charge the low-voltage cell. This method of manually charging the battery cell using the wires has the following drawbacks: unstable contact between the wires and the cell terminals, easily leading to poor contact, causing terminal burnout and sparking during charging; the worker directly holding the wires poses a safety hazard; and the high contact resistance and significant heat generation between the external charging / discharging device's wires and the module terminals result in low efficiency.

[0019] The technical solution provided by this utility model has the following advantages:

[0020] 1. The battery cell charging and discharging fixture provided by this utility model includes an installation structure, a lifting structure, and a contact structure. The installation structure includes a support member and a mounting member. The support member is suitable for being set on a working plane and is suitable for bearing the component to be tested. The mounting member is set on the support member. The lifting structure includes a lifting component and a driving component slidably set on the mounting member. The driving end of the driving component is connected to the lifting component so that, under the action of an external force, the driving end of the driving component drives the lifting component to slide relative to the mounting member. The contact structure includes a contact component and a charging component. The contact component is set on the lifting component, and its contact end passes through the lifting component. The charging component is set on the mounting member, and one end of it is connected to the contact component, and the other end is connected to an external power source. Under the action of an external force, the driving component is suitable for driving the lifting component to slide relative to the mounting member so that the contact end of the contact component on the lifting component contacts the component to be tested, or separates the contact end of the contact component from the component to be tested.

[0021] This battery cell charging and discharging fixture features a lifting structure and a contact structure mounted on a mounting structure. The mounting structure includes a support member and a mounting component. The support member is positioned on a working plane under external force and can support the component to be tested. The mounting component is mounted vertically on the support member. The lifting structure includes a lifting assembly and a drive assembly slidably mounted on the mounting component. The drive end of the drive assembly is connected to the lifting assembly, allowing the drive end to drive the lifting assembly to slide relative to the mounting component under external force. The contact assembly includes a contact component and a charging component. The contact component is mounted on the lifting assembly, allowing it to slide synchronously with the lifting assembly relative to the mounting component. The contact end of the contact component penetrates the lifting assembly, allowing it to contact the component to be tested mounted on the support member when sliding relative to the mounting component. The charging component... The charging component is placed on the mounting bracket, with one end connected to the contact component and the other end connected to an external power source. This allows the charging component to deliver power to the contact component. When the contact component contacts the component to be tested on the support bracket, it delivers power to the component to recharge it. After recharging, the lifting component, driven by the drive component, moves the contact component away from the component to make room for the component that has been recharged and is about to be recharged. This avoids manual recharging and improves the recharging efficiency. When discharging is required, the charging component is disconnected from the external power source, and the drive component drives the lifting component to contact the contact component with the component. This allows the power inside the component to be discharged through the contact component and the charging component, thus completing the discharge process.

[0022] 2. The battery cell charging and discharging fixture provided by this utility model includes a contact component comprising a first contact and a second contact spaced apart on a lifting component, the first and second contacts serving together as the contact ends of the contact component.

When the lifting assembly is driven by the driving end of the driving assembly to move the contact assembly away from the test piece on the support, the first contact can separate from the positive electrode of the test piece, and the second contact can separate from the negative electrode of the test piece, so as to make room for the test piece. The charging assembly includes a first charging component and a second charging component spaced apart on the mounting component. In this embodiment, the first charging component and the second charging component are respectively a first flexible busbar and a second flexible busbar.

[0043] Example

[0044] This embodiment provides a battery cell charging and discharging fixture, such as... Figures 1 to 6As shown, the structure includes an installation structure 1, a lifting structure 2, and a contact structure 3. The installation structure 1 includes a support member 11 and a mounting member 12. The support member 11 is adapted to be mounted on a working plane and is adapted to support the part to be tested 5. The mounting member 12 is mounted on the support member 11. The lifting structure 2 includes a lifting component 21 and a driving component 22 slidably mounted on the mounting member 12. The driving end of the driving component 22 is connected to the lifting component 21 so that under the action of an external force, the driving end of the driving component 22 drives the lifting component 21 to slide relative to the mounting member 12. The contact structure 3 includes a contact component 31 and a charging component 32. The contact component 31 is mounted on the lifting component 21, and its contact end is disposed through the lifting component 21. The charging component 32 is mounted on the mounting member 12, and one end of its charging component 32 is connected to the contact component 31, and the other end is connected to an external power source. Under the action of an external force, the driving component 22 is adapted to drive the lifting component 21 to slide relative to the mounting member 12 so that the contact end of the contact component 31 on the lifting component 21 contacts the part to be tested 5, or separates the contact end of the contact component 31 from the part to be tested 5.

[0045] The battery cell charging and discharging fixture described above utilizes a lifting structure 2 and a contact structure 3 mounted on a mounting structure 1. The mounting structure 1 specifically includes a support member 11 and a mounting member 12. In this embodiment, the support member 11 and the mounting member 12 are a support plate and a mounting plate, respectively. The support member 11 can be positioned on a working plane under external force and can support the component to be tested 5, which is a battery cell in this embodiment. The mounting member 12 is mounted on the support member 11, specifically vertically. The lifting structure 2 specifically includes a lifting assembly 21 and a driving assembly 22 slidably mounted on the mounting member 12. The driving assembly 22... The drive end is connected to the lifting component 21, so that under the action of external force, the drive end of the drive component 22 can drive the lifting component 21 to slide relative to the mounting component 12; while the contact component 31 includes a contact component 31 and a charging component 32, wherein the contact component 31 is disposed on the lifting component 21, so that when the lifting component 21 slides relative to the mounting component 12, the contact component 31 can slide synchronously relative to the mounting component 12 with the lifting component 21. At the same time, the contact end of the contact component 31 is disposed through the lifting component 21, so that when the contact component 31 slides relative to the mounting component 12, the contact end of the contact component 31 can contact the test component 5 disposed on the support component 11.

[0046] In addition, the charging component 32 is mounted on the mounting member 12, with one end of the charging component 32 connected to the contact component 31 and the other end connected to an external power source. This allows the charging component 32 to deliver power to the contact component 31. When the contact component 31 contacts the test piece 5 on the support member 11, the contact component 31 can deliver power to the test piece 5 to perform the power replenishment work. After the power replenishment work of the test piece 5 is completed, the lifting component 21 can also drive the contact component 31 away from the test piece 5 under the drive of the drive end of the drive component 22, so as to make room for the test piece 5 that has been replenished and the test piece 5 that is about to be replenished. In this way, manual power replenishment operation of the test piece 5 is avoided and the power replenishment efficiency of the test piece 5 is improved.

[0047] When it is necessary to discharge the test piece 5, the connection between the charging component 32 and the external power source can be disconnected, and the lifting component 21 can be driven by the driving end of the driving component 22 to make the contact component 31 contact the test piece 5, so that the power in the test piece 5 can be discharged through the contact component 31 and the charging component 32, thereby completing the discharge operation of the test piece 5.

When the lifting component 21 slides relative to the mounting component 12, the first contact 311 is adapted to contact or separate from the positive electrode of the component to be tested 5, and the second contact 312 is adapted to contact or separate from the negative electrode of the component to be tested 5.

[0049] The battery cell charging and discharging fixture described above includes a contact component 31 comprising a first contact 311 and a second contact 312 spaced apart on the lifting component 21. In this embodiment, the first contact 311 and the second contact 312 are respectively a first probe and a second probe. The first contact 311 and the second contact 312 together serve as the contact ends of the contact component 31. When the lifting component 21 is driven by the driving end of the driving component 22 to move the contact component 31 closer to the test piece 5 on the support member 11, the first contact 311 can contact the positive electrode of the test piece 5, and the second contact 312 can contact the negative electrode of the test piece 5, so as to charge the test piece 5 through the charging component 32. When the lifting component 21 is driven by the driving end of the driving component 22 to move the contact component 31 away from the test piece 5 on the support member 11, the first contact 311 can separate from the positive electrode of the test piece 5, and the second contact 312 can separate from the negative electrode of the test piece 5, so as to make room for the test piece 5.

[0053] The battery cell charging and discharging fixture with the above structure, by setting the charging component 32, also includes a first insulating member 323 and a second insulating member 324. In this embodiment, the first insulating member 323 and the second insulating member 324 are respectively the first insulator and the second insulator.

[0061] The battery cell charging and discharging fixture with the above structure has two guide portions 121 provided on the mounting member 12. In this embodiment, the guide portion 121 is a guide groove. The two guide portions 121 are spaced apart, and each guide member 212 is slidably connected to one guide portion 121, thereby realizing the sliding connection between the guide member 212 and the mounting member 12, and thus enabling the lifting member 211 to slide relative to the mounting member 12.

[0062] The battery cell charging and discharging fixture provided in this embodiment, such as Figure 2 As shown, the mounting component 12 is also provided with an adjustment part 122, and the drive component 22 is slidably connected to the adjustment part 122 so that the drive component 22 is slidably connected to the mounting component 12.

[0063] The battery cell charging and discharging fixture described above has an adjustment part 122 provided on the mounting part 12. In this embodiment, the adjustment part 122 is an adjustment groove. The drive component 22 is slidably connected to the adjustment part 122, so that the drive component 22 can be slidably connected to the mounting part 12. This allows the drive component 22 and the lifting component 21 to be synchronously adjusted on the mounting part 12 to accommodate test pieces 5 of different sizes.

[0064] The battery cell charging and discharging fixture provided in this embodiment, such as Figure 1 and Figure 5 As shown, it also includes a carrier 4, which is disposed on the support 11 and is adapted to carry the test piece 5.

[0065] The battery cell charging and discharging fixture described above uses a carrier 4 mounted on the support 11. In this embodiment, the carrier 4 is a carrier plate. The carrier 4 can support the component to be tested 5 and can adjust its position relative to the support 11 under external force, thereby allowing the position of the component to be tested 5 to be adjusted so that the component to be tested 5 can contact the component 31.

[0066] The battery cell charging and discharging fixture provided by this utility model includes a lifting structure 2 and a contact structure 3 mounted on a mounting structure 1. The mounting structure 1 specifically includes a support member 11 and a mounting member 12. The support member 11 can be mounted on a working plane under external force and can support the component 5 to be tested. The mounting member 12 is mounted on the support member 11, specifically vertically mounted on the support member 11. The lifting structure 2 specifically includes a lifting assembly 21 and a driving assembly 22 slidably mounted on the mounting member 12. The driving end of the driving assembly 22 is connected to the lifting assembly 21, thereby enabling external... Under the action of force, the driving end of the driving component 22 can drive the lifting component 21 to slide relative to the mounting member 12; while the contact component 31 includes a contact component 31 and a charging component 32, wherein the contact component 31 is disposed on the lifting component 21, so that when the lifting component 21 slides relative to the mounting member 12, the contact component 31 can slide synchronously with the lifting component 21 relative to the mounting member 12. At the same time, the contact end of the contact component 31 is disposed through the lifting component 21, so that when the contact component 31 slides relative to the mounting member 12, the contact end of the contact component 31 can contact the object to be tested disposed on the support member 11. The test piece 5 makes contact, and the charging component 32 is mounted on the mounting component 12. One end of the charging component 32 is connected to the contact component 31, and the other end is connected to an external power source, so that the charging component 32 can deliver power to the contact component 31. When the contact component 31 makes contact with the test piece 5 on the support component 11, the contact component 31 can deliver power to the test piece 5 to perform the power replenishment work on the test piece 5. After the power replenishment work on the test piece 5 is completed, the lifting component 21 can also drive the contact component 31 away from the test piece under the drive end of the drive component 22. 5. To make room for the test piece 5 that has been charged and the test piece 5 that is about to be charged, manual charging of the test piece 5 is avoided and the charging efficiency of the test piece 5 is improved. When it is necessary to discharge the test piece 5, the connection between the charging component 32 and the external power supply can be disconnected, and the lifting component 21 can be driven by the driving end of the driving component 22 to make contact component 31 contact with the test piece 5, so that the power in the test piece 5 can be discharged through the contact component 31 and the charging component 32, thereby completing the discharge operation of the test piece 5.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
