[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] like Figures 1-7 As shown, this embodiment proposes a battery water bath testing fixture, including a water bath 1, wherein the water bath 1 contains a mixed liquid such as ethylene glycol and pure water, and further includes:

[0025] Multiple fixing block groups, each fixing block group includes two fixing blocks 2 respectively fixed on the inner walls of the two sides of the water bath tank 1 and used to fix the two side tabs of the battery 10 (the two fixing blocks 2 on the inner walls of the two sides are used to fix the positive and negative tabs of the battery 10 respectively), and each fixing block 2 extends along the depth direction of the water bath tank 1 and has a fixing groove I 3 on its inner side.

[0026] The movable plate 4 is located at the upper opening of the water bath 1 (which can cover the water bath 1 and allow the battery 10 to be tested inside the water bath 1). Multiple movable blocks 5 slide at its lower end. Each movable block 5 passes through the movable plate 4 and can slide bidirectionally along the width direction of the water bath 1. It is provided with a fixing groove II 6 for fixing the battery tabs. The positions of fixing groove I 3 and fixing groove II 6 are set accordingly.

[0027] Thus, for charging and discharging tests on batteries that meet the end tabs of the two fixed slots I3 of each fixed block group, the batteries 10 that meet the end tabs can be inserted along the two opposite fixed slots I3 without the need for bolt installation or other operations. Furthermore, the fixed slots I3 extend along the depth direction of the water bath 1, accommodating batteries of different heights for water bath testing. Simultaneously, a movable plate 4 is provided at the opening at the top of the water bath 1. A movable block 5 sliding on the movable plate 4 has a fixed slot II6. The movable block 5 can slide along the width direction of the water bath 1, accommodating batteries of different widths and enabling water bath testing of batteries of varying widths. This results in high testing efficiency and strong testing consistency.

[0028] Furthermore, such as Figure 1 , Figure 3 and Figure 4As shown, the fixing groove I3 extends along the length of the fixing block 2, and the fixing block 2 is designed as a U-shaped structure I, with the fixing groove I located in the concave part of the U-shaped structure I. Specifically, one side of the inner wall of the fixing groove I3 is provided with an elastic serrated structure I7, and the battery tabs are located between the elastic serrated structure I7 and the other side of the inner wall of the fixing groove I3, and are in close contact. Both the inner wall of the fixing groove I3 and the elastic serrated structure I7 are conductive, which satisfies the application of batteries with dual-sided tabs and allows for the placement of batteries with various height models. The elastic serrated structure I7 ensures that the battery tabs are in close contact with the inner wall under certain pressure, guaranteeing that the battery charging and discharging are normal.

[0029] Specifically, the fixing blocks are set into two groups, and the two groups of fixing blocks are distributed at intervals along the front and back direction of the inner wall of the water bath tank 1.

[0030] In this embodiment, as Figure 2 and Figures 5-7 As shown, the movable block 5 is designed with an I-shaped structure, penetrating the movable plate 4. The lower part of the I-shaped structure has a U-shaped structure II, and the fixing groove II6 is located within the concave portion of the U-shaped structure II. One side of the inner wall of the fixing groove II6 is provided with an elastic serrated structure II8, and the battery tab is located between the elastic serrated structure II8 and the other side of the inner wall of the fixing groove II6, and is in close contact with it. Both the inner wall of the fixing groove II6 and the elastic serrated structure II8 are conductive, satisfying the requirements for battery applications with a single-sided tab structure.

[0031] Furthermore, the movable plate 4 is provided with multiple track grooves 9. The upper part of the I-shaped structure slides within the track grooves 9. Each track groove 9 extends along the width direction of the water bath 1, and two movable blocks 5 slide on each track groove 9. The fixing grooves II6 on the two movable blocks 5 of the same track groove 9 are arranged opposite to each other, and the two fixing grooves II6 are respectively arranged opposite to the two fixing grooves I3 on ​​the inner walls of both sides of the water bath 1. This can meet the charging and discharging test of batteries with single-sided tabs. The fixing grooves II6 on the movable blocks 5 can move freely on the movable plate 4 through the track grooves 9. By moving in opposite directions to fix the batteries with single-sided tabs, it can adapt to batteries of different widths and can accommodate batteries of different widths for water bath testing. The testing efficiency is high and the testing consistency is strong.

[0032] Specifically, there are two track grooves 9, which are distributed at intervals along the front and rear direction of the moving plate 4. The moving blocks 5 on the front and rear track grooves 9 correspond to the positions of the fixed blocks 2 of the front and rear fixed block groups, respectively.

[0033] It should be noted that the fixed slot II6 can be bidirectionally moved to connect the battery with the single-sided tab structure via the track slot 9, preventing the positive and negative terminals of the battery from being connected and short-circuited when moving in the same direction; at the same time, after the battery is connected to the fixed slot II6, the battery can be placed in the water bath for charging and discharging test verification.

[0034] It should be noted that the elastic serrated structure I7 and elastic serrated structure II8 in this embodiment are designed as highly elastic structures, which can effectively make the tabs and the overcurrent contact surface in close contact.

[0035] In summary, when the battery has a single-sided tab structure, it can move towards each other on the track groove 9 through the fixed groove Ⅱ6, so that the elastic serrated structure Ⅱ8 squeezes the battery tab, making the battery tab in close contact with the non-elastic serrated structure side in the fixed groove Ⅱ8, which satisfies the requirement of the test cabinet to perform charge and discharge tests on the battery through the fixed groove Ⅱ8.

[0036] When the battery has a dual-sided tab structure, the battery tabs can be inserted into the corresponding positive and negative terminals of the fixed slot I3 respectively. The battery tabs are squeezed by the elastic serrated structure I7, so that the battery tabs are in close contact with the non-elastic serrated structure side in the fixed slot I3, which satisfies the requirement of the test cabinet to perform charge and discharge tests on the battery through the fixed slot I3.

[0037] The battery water bath testing fixture in this embodiment can meet the charging and discharging tests of batteries of different heights, widths, shapes and models, effectively improve battery testing efficiency, reduce testing errors, meet the requirements of high efficiency and high quality, and ensure the consistency, accuracy and uniformity of the test.
