Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0034] like Figures 1 to 4 As shown, this utility model embodiment provides a charge-discharge testing device for testing and analyzing battery cells or batteries. The charge-discharge testing device includes:

[0035] The support plate 1 has a first receiving groove 11, a second receiving groove 12 and an assembly through groove 13 on its top surface. The second receiving groove 12 and the assembly through groove 13 are located at different positions on one side of the first receiving groove 11. The first receiving groove 11 is used to accommodate batteries or cells. The assembly through groove 13 is set through the top and bottom surfaces of the support plate 1.

[0036] Test plate 2 is installed in the second receiving groove 12. The side of test plate 2 facing the first receiving groove 11 is provided with conductive contact part 21. Test plate 2 is in contact with the positive and negative electrodes of the battery through conductive contact part 21.

[0037] The active component 3 is movably connected in the assembly slot 13. A test probe 31 is provided on the end face of the active component 3 facing the first receiving slot 11. The test probe 31 is used to contact the positive and negative electrodes included in the battery cell.

[0038] As can be seen from the above embodiments, in this application embodiment, since the top surface of the support plate 1 is provided with a first receiving groove 11, a second receiving groove 12 and an assembly through groove 13, the second receiving groove 12 and the assembly through groove 13 are located at different positions on one side of the first receiving groove 11. The first receiving groove 11 is used to accommodate batteries or cells. Therefore, cells or batteries can be installed through the first receiving groove 11, and the cells or batteries can be positioned through the first receiving groove 11 to avoid displacement of cells or batteries during testing and analysis, and to facilitate the installation and removal of batteries or cells. Since the test plate 2 is installed in the second receiving groove 12, and the side of the test plate 2 facing the first receiving groove 11 is provided with a conductive contact part 21, the test plate 2 contacts the positive and negative electrodes of the battery through the conductive contact part 21. The movable component 3 is movably connected in the assembly through groove 13, and the end face of the movable component 3 facing the first receiving groove 11 is provided with a test probe 31. The test probe 31 is used to contact the positive and negative electrodes of the battery cell. Therefore, the test plate 2 can directly contact the positive and negative electrodes of the battery through the conductive contact part 21 to realize the charge and discharge test of the battery, and the test probe 31 provided by the movable component 3 can directly contact the positive and negative electrodes of the battery cell to realize the charge and discharge test of the battery cell. In summary, the charge-discharge testing device provided by the embodiments of this application can not only complete the charge-discharge test of the battery, but also complete the charge-discharge test of the cell. Moreover, the charge-discharge testing device is not limited by the structure of the battery and cell, and can perform charge-discharge tests even if the battery or cell has tabless. This not only reduces the manufacturing cost of the charge-discharge testing device, but also improves the utilization rate of the charge-discharge testing device.

[0039] The supporting plate 1 is a plate-shaped structure, which can be rectangular, circular, or other shapes. This embodiment does not limit the specific shape. The supporting plate 1 has a top surface and a bottom surface facing away from each other. A first receiving groove 11 and a second receiving groove 12 are formed on the top surface. Both the first receiving groove 11 and the second receiving groove 12 are groove structures. The shape of the first receiving groove 11 is determined according to the shape of the battery and the shape of the battery cell. The assembly through groove 13 is a through hole structure formed on the supporting plate 1. The shape of the assembly through groove 13 is determined according to the shape of the movable component 3. The second receiving groove 12 and the assembly through groove 13 are located at different positions on one side of the first receiving groove 11; in other words, the second receiving groove 12 and the assembly through groove 13 are formed at different positions around the first receiving groove 11.

[0040] Test board 2 is a motherboard device that performs battery charging and discharging, functional testing, or manual analysis. Typically, test board 2 can have multiple test pins, including positive terminal test pins, negative terminal test pins, clock line test pins, and data line test pins. Test board 2 is installed in the second receiving slot 12. Since the second receiving slot 12 is located on one side of the first receiving slot 11, it facilitates electrical connection between test board 2 and the battery installed in the first receiving slot 11. Specifically, a conductive contact portion 21 is provided on the side wall of test board 2 near the first receiving slot 11. This conductive contact portion 21 can be a metal snap-fit ​​structure, a metal fastening structure, or other conductive structures; this embodiment does not limit this. The battery includes a positive terminal and a negative terminal. The conductive contact portion 21 allows direct contact with the positive and negative terminals of the battery, thereby enabling charge and discharge testing of the battery. It should be noted that the battery in this embodiment is a type of steel-cased battery.

[0041] Furthermore, in this embodiment, the movable component 3 is movable along the assembly slot 13, allowing the test probe 31 disposed on the end face of the movable component 3 to move towards or away from the first receiving slot 11. The movable component 3 can be a sliding structure, a cylinder push rod structure, or other structures capable of linear movement. At least one end face of the movable component 3 can face the first receiving slot 11, and the test probe 31 is disposed on this first end face. When the movable component 3 approaches the first receiving slot 11, the test probe 31 can eventually make contact with the positive and negative electrodes of the battery cell.

[0042] In some embodiments, a first notch structure 111 is provided on the first wall of the first receiving groove 11, and a second notch structure 112 is provided on the second wall of the first receiving groove. The first notch structure 111 is connected to the second receiving groove 12, and the second notch structure 112 is connected to the assembly through groove 13. The plane containing the first groove wall intersects with the plane containing the second groove wall.

[0043] In this embodiment, the first notch structure 111 is a through-slot or through-hole structure provided on the first wall of the first receiving groove 11, so as to connect the first receiving groove 11 and the second receiving groove 12 through the first notch structure 111. The second notch structure 112 is a through-slot or through-hole structure provided on the first wall, so as to connect the first receiving groove 11 and the assembly through-slot 13 through the second notch structure 112. In this way, since the first notch structure 111 and the second receiving groove 12 are connected, and the second notch structure 112 and the assembly through-slot 13 are connected, the contact between the conductive contact portion 21 and the positive and negative electrodes of the battery can be achieved at the first notch structure 111, and the contact between the test probe 31 and the positive and negative electrodes of the battery cell can be achieved at the second notch structure 112. It should be noted that the first receiving groove 11 can be a rectangular groove structure, and the first groove wall and the second groove wall can be two adjacent groove walls of the first receiving groove 11, so that the plane where the first groove wall is located intersects the plane where the second groove wall is located, thereby ensuring that the setting position of the second receiving groove 12 and the setting position of the assembly through-slot 13 do not interfere with each other.

[0044] Furthermore, it should be noted that in some embodiments, the distance between the bottom and the opening of the first receiving groove 11 should be greater than the distance between the bottom and the opening of the second receiving groove 12. This allows the top surface of the test board 2 installed in the second receiving groove 12 to be on the same plane as the top surface of the battery installed in the first receiving groove 11, facilitating the electrical connection between the battery and the test board 2.

[0045] In some embodiments, the active component 3 includes a sliding plate 32 and a sliding rod 33. The sliding rod 33 is disposed on the third groove wall of the assembly through groove 13 and extends toward the first receiving groove 11. The third groove wall and the first receiving groove 11 are in a relative position. A test probe 31 is mounted on the end face of the sliding plate 32 facing the first receiving groove 11. A sliding through hole is provided on the sliding plate 32, and the sliding rod 33 is slidably connected in the sliding through hole.

[0046] In this embodiment, the movable component 3 includes a sliding plate 32 and a sliding rod 33. The sliding rod 33 is disposed on the third groove wall of the assembly through groove 13 and extends towards the first receiving groove 11. The test probe 31 is mounted on the end face of the sliding plate 32 facing the first receiving groove 11. A sliding through hole is provided on the sliding plate 32, and the sliding rod 33 is slidably connected in the sliding through hole. Therefore, the sliding plate 32 can slide along the extension direction of the sliding rod 33 and can move closer to or away from the first receiving groove 11 under the guidance of the sliding rod 33, so that the test probe 31 and the positive and negative electrodes of the battery cell can contact or separate. Throughout the process, since the test probe 31 and the positive and negative electrodes of the battery cell can be contacted or separated simply by sliding the sliding plate 32, the operation of the above-mentioned movement process is more convenient and faster. In addition, it should be noted that there can be at least two sliding rods 33. Thus, by using at least two sliding rods 33, the stability of the sliding plate 32 during the sliding process can be ensured, and the tightness of the contact between the test probe 31 and the positive and negative electrodes of the battery cell can be guaranteed.

[0047] In some embodiments, a first limiting groove 131 and a second limiting groove 132 are provided on two opposing fourth groove walls of the assembly through groove 13. The first limiting groove 131 is located close to the first receiving groove 11, and the second limiting groove 132 is located away from the first receiving groove 11. The plane where the fourth groove wall is located intersects the plane where the third groove wall is located. When the test probe 31 and the battery cell are electrically connected, the sliding plate 32 is engaged in the first limiting groove 131. When the test probe 31 and the battery cell are separated, the sliding plate 32 is engaged in the second limiting groove 132.

[0048] In this embodiment, since the first limiting groove 131 and the second limiting groove 132 are provided on the two opposite fourth groove walls of the assembly through groove 13, the first limiting groove 131 is located close to the first receiving groove 11, and the second limiting groove 132 is located away from the first receiving groove 11. The plane where the fourth groove wall is located intersects the plane where the third groove wall is located. Therefore, when it is necessary for the test probe 31 to contact the positive and negative electrodes of the battery cell, the sliding plate 32 can be slid to the first limiting groove 131 and locked in the first limiting groove 131. This ensures the tightness of the contact between the test probe 31 and the positive and negative electrodes of the battery cell and avoids affecting the accuracy of the battery cell charging and discharging test due to the displacement of the test plate 2. Simultaneously, when it is necessary to separate the test probe 31 from the positive and negative electrodes of the battery cell, the sliding plate 32 can slide to the second limiting groove 132 and engage within it. The second limiting groove 132 ensures the sliding plate 32 remains relatively stable, thus preventing interference from the moving component 3 to the battery during charge / discharge testing. It should be noted that the first limiting groove 131 can be positioned where the two fourth walls of the mounting groove 13 contact the sidewall of the sliding plate 32 when the test probe 31 and the positive and negative electrodes of the battery cell are in complete contact. Similarly, the second limiting groove 132 can be positioned where the two fourth walls of the mounting groove 13 contact the sidewall of the sliding plate 32 when the test probe 31 and the positive and negative electrodes of the battery cell are completely separated.

[0049] In some embodiments, the active component 3 further includes an elastic element that is sleeved on the sliding rod 33. When the sliding plate 32 is engaged in the second limiting groove 132, the elastic element is in a compressed state, and when the sliding plate 32 is engaged in the first limiting groove 131, the elastic element is in a restoring deformation state.

[0050] In this embodiment, the elastic element can be any of the components with elastic restoring force, such as a spring or a rubber ring. Taking a spring as an example, one end of the spring can abut against the sliding plate 32, the spring is sleeved on the sliding rod 33, and the other end of the spring abuts against the groove wall of the mounting groove 13 facing the first receiving groove 11. In this way, when the sliding plate 32 is engaged in the second limiting groove 132, the elastic element is in a compressed state. Subsequently, when it is necessary to make the test probe 31 and the positive and negative electrodes of the battery cell fully contacted, the sliding plate 32 can be engaged in the first limiting groove 131. Then, under the restoring force of the elastic element, i.e., the elastic force of the elastic element, the tightness of the contact between the test probe 31 and the positive and negative electrodes of the battery cell can be ensured.

[0051] In some embodiments, the first receiving groove 11 is provided with an unlocking groove 14 on the side away from the second receiving groove 12, and the unlocking groove 14 is provided through the top and bottom surfaces of the supporting plate 1.

[0052] In this embodiment, since the first receiving groove 11 is provided with an unfastening groove 14 on the side away from the second receiving groove 12, and the unfastening groove 14 is provided through the top and bottom surfaces of the supporting plate 1, when the battery cell or battery is taken out of the first receiving groove 11, the unfastening groove 14 can provide a force application space, making it easy to take out the battery cell or battery from the first receiving groove 11.

[0053] In some embodiments, the conductive contact portion 21 includes a conductive connector and a test pin. One end of the conductive connector is fastened to the test pin, and the other end of the conductive connector is in contact with the positive and negative terminals of the battery through the first notch structure 111.

[0054] In this embodiment, since the conductive contact 21 includes a conductive connector and a test pin, one end of the conductive connector is fastened to the test pin, and the other end of the conductive connector contacts the positive and negative terminals of the battery through the first notch structure 111. Therefore, the stability of the electrical connection between the battery and the test board 2 can be indirectly ensured through the fastening between the conductive connector and the test pin. It should be noted that the conductive connector can be one or more of the following components: a snap-fit ​​structure, an elastic sheet, etc., which facilitates the connection between the conductive connector and the test pin through the fastening method, and at the same time helps to ensure the stability of the electrical connection between the battery and the test board 2.

[0055] In some embodiments, the sliding plate 32 is a magnetic element. This allows the sliding plate 32 to be attracted to the side wall of the battery cell, further ensuring the tightness of the contact between the test probe 31 and the positive and negative electrodes included in the battery cell.

[0056] In some embodiments, the charge-discharge test apparatus further includes a mounting platform 4, a plug-in terminal 5, and a charge-discharge device. The support plate 1 is detachably connected to the mounting platform 4. A wire harness guide structure 41 is provided on one side of the support plate 1 on the mounting platform 4. The plug-in terminal 5 is provided at the edge of the support plate 1. The plug-in terminal 5 and the charge-discharge device are electrically connected by wires. The wires are at least run through the wire harness guide structure 41.

[0057] In this embodiment, since the charge / discharge testing device also includes a mounting platform 4, plug-in terminals 5, and a charge / discharge device, and the carrier plate 1 is detachably connected to the mounting platform 4, the mounting platform 4 can provide sufficient installation space for the carrier plate 1. Furthermore, since a wire harness guide structure 41 is provided on one side of the carrier plate 1 on the mounting platform 4, and the plug-in terminals 5 are located at the edge of the carrier plate 1, the plug-in terminals 5 and the charge / discharge device are electrically connected via wires. The wires pass through the wire harness guide structure 41 at least, thus guiding the wires to connect to the plug-in terminals 5, ensuring the stability of the electrical connection between the charge / discharge device and the plug-in terminals 5.

[0058] In some embodiments, the number of first receiving grooves 11, second receiving grooves 12, and assembly through grooves 13 provided on the support plate 1 are all multiple, and the multiple first receiving grooves 11 are arranged along the first direction, the multiple second receiving grooves 12 are arranged along the first direction, the multiple assembly through grooves 13 are arranged along the first direction, the number of test plates 2 is equal to the number of second receiving grooves 12, and the number of movable components 3 is equal to the number of assembly through grooves 13, wherein the first direction is consistent with the extension direction of the top surface of the support plate 1.

[0059] In this embodiment, since the number of first receiving grooves 11, second receiving grooves 12, and assembly through grooves 13 provided on the support plate 1 are all multiple, and the multiple first receiving grooves 11 are arranged along the first direction, the multiple second receiving grooves 12 are arranged along the first direction, the multiple assembly through grooves 13 are arranged along the first direction, the number of test plates 2 is equal to the number of second receiving grooves 12, and the number of movable components 3 is equal to the number of assembly through grooves 13, the charge and discharge test device provided in this application embodiment can simultaneously perform charge and discharge tests on multiple batteries or multiple cells, thereby not only improving the charge and discharge test efficiency of batteries and cells, but also saving the manufacturing cost of the charge and discharge test device.

[0060] In this embodiment, the top surface of the support plate 1 is provided with a first receiving groove 11, a second receiving groove 12 and an assembly through groove 13. The second receiving groove 12 and the assembly through groove 13 are located at different positions on one side of the first receiving groove 11. The first receiving groove 11 is used to accommodate batteries or cells. Therefore, cells or batteries can be installed through the first receiving groove 11, and the cells or batteries can be positioned through the first receiving groove 11 to prevent the cells or batteries from shifting during testing and analysis, and to facilitate the installation and removal of batteries or cells. Since the test plate 2 is installed in the second receiving groove 12, and the side of the test plate 2 facing the first receiving groove 11 is provided with a conductive contact part 21, the test plate 2 contacts the positive and negative terminals of the battery through the conductive contact part 21. The movable component 3 is movably connected in the assembly through groove 13, and the end face of the movable component 3 facing the first receiving groove 11 is provided with a test probe 31, which contacts the positive and negative terminals of the battery cell. Therefore, the test plate 2 can directly contact the positive and negative terminals of the battery through the conductive contact part 21 to realize the charge and discharge test of the battery, and the test probe 31 provided by the movable component 3 can directly contact the positive and negative terminals of the battery cell to realize the charge and discharge test of the battery cell. In summary, the charge-discharge testing device provided by the embodiments of this application can not only complete the charge-discharge test of the battery, but also complete the charge-discharge test of the cell. Moreover, the charge-discharge testing device is not limited by the structure of the battery and cell, and can perform charge-discharge tests even if the battery or cell has tables. This not only reduces the manufacturing cost of the charge-discharge testing device, but also improves the utilization rate of the charge-discharge testing device.
