[0030] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] Example 1

[0032] In related technologies, charge-discharge tests are required during battery production to assess battery capacity and performance, ensuring that product quality and lifespan meet standards. During battery testing, clamps are used to hold and secure the battery to ensure accurate current and voltage measurements. However, the battery may overheat during cyclic charge-discharge cycles, affecting test results.

[0033] To solve the above technical problems, refer to Figure 1 As shown, an embodiment of this application provides a battery test fixture 100, which includes a housing 110, an adjustment plate 120, and an adjustment member 130.

[0034] Specifically, in combination Figure 1 and Figure 2As shown, a mounting hole 112 and a through groove 111 are provided on one side of the housing 110; an adjusting plate 120 is disposed in the through groove 111, and the adjusting plate 120 and the side of the housing 110 away from the mounting hole 112 define a receiving space for accommodating the battery. The adjusting plate 120 is provided with a plurality of first heat dissipation holes 121; an adjusting member 130 passes through the mounting hole 112, and one end of the adjusting member 130 is connected to the adjusting plate 120; so that the adjusting member 130 can drive the adjusting plate 120 to move, placing the battery in the receiving space of the housing 110, and the adjusting plate 120 and The housing 110 has one side working together to clamp the battery. The adjustment plate 120 is set in the through groove 111 of the housing 110 to reduce the damage caused by the battery adjustment plate 120 after separation. The through groove 111 of the housing 110 can protect the battery and improve the protection performance during battery testing. The adjustment member 130 can pass through the mounting hole 112 of the housing 110 to adjust the adjustment plate 120 and change the position of the adjustment plate 120 to fix and limit the battery, so as to facilitate subsequent battery performance testing. The adjustment plate 120 is provided with a first heat dissipation hole 121 for heat dissipation of the battery and to improve the heat dissipation and cooling effect.

[0035] It is understood that the shape of the adjusting plate 120 and the through groove 111 is not specifically limited. The adjusting plate 120 can be square, round, rectangular or rhomboid. Correspondingly, the size and shape of the through groove 111 need to be adapted to the adjusting plate 120 so that the walls of the adjusting plate 120 and the through groove 111 can jointly clamp and fix the battery.

[0036] In this application, the battery testing fixture 100 is used to hold the battery. The battery can be a lithium-ion secondary battery, a lithium-ion primary battery, a lithium-sulfur battery, a sodium-lithium-ion battery, a sodium-ion battery, a lithium metal battery, or a magnesium-ion battery, etc., and the embodiments of this application do not limit this.

[0037] Combination Figures 1 to 3 As shown, the battery testing fixture 100 has a first direction Z, a second direction X, and a third direction Y, wherein the first direction Z, the second direction X, and the third direction Y are arranged perpendicularly to each other. For example, the first direction Z is the height direction of the battery testing fixture 100, the second direction X is the length direction of the battery testing fixture 100, and the third direction Y is the width direction of the battery testing fixture 100.

[0038] In one embodiment, alternatively, referencing Figure 1 and Figure 3As shown, the housing 110 has a plurality of second heat dissipation holes 113 on the side away from the mounting hole 112. The second heat dissipation holes 113 are arranged opposite to the first heat dissipation holes 121. The second heat dissipation holes 113 of the housing 110 and the first heat dissipation holes 121 of the adjustment plate 120 work together to dissipate heat and cool the battery. The first heat dissipation holes 121 and the second heat dissipation holes 113 are arranged along the second direction X and the third direction Y to improve heat dissipation efficiency and have a better heat dissipation effect.

[0039] Alternatively, as Figure 1 As shown, the plurality of first heat dissipation holes 121 are arranged in an m*n array structure, and the plurality of second heat dissipation holes 113 are arranged in an m*n array structure, where n≥2 and m≥2. Accordingly, the plurality of first heat dissipation holes 121 are arranged in an array structure, and the plurality of second heat dissipation holes 113 are arranged in an array structure, which promotes air circulation and heat exchange and improves heat dissipation efficiency.

[0040] In one embodiment, alternatively, referencing Figure 1 and Figure 3 As shown, there are multiple adjusting members 130, which are respectively located around the perimeter of the housing 110. Correspondingly, the adjusting members 130 are located around the perimeter of the housing 110, and together they adjust the position of the adjusting plate 120, causing the adjusting plate 120 to move. The adjusting plate 120 abuts against one side of the battery to clamp and fix it. At this time, the adjusting plate 120 is located between the adjusting members 130 and the battery, reducing the possibility of battery misalignment or movement. For example, the multiple adjusting members 130 are at the same height and are arranged along the second direction X and the third direction Y.

[0041] Optionally, combined Figure 1 and Figure 2 As shown, the adjusting member 130 is an adjusting bolt. The adjusting bolt can pass through the mounting hole 112 and is screwed to the hole wall of the mounting hole 112. Correspondingly, the adjusting bolt passes through the mounting hole 112 in the first direction Z, and can be adjusted through the hole wall of the mounting hole 112. The adjusting bolt abuts against the adjusting plate 120. When the battery is clamped on the side of the adjusting plate 120 away from the adjusting bolt, the adjusting bolt abuts against the adjusting plate 120 and applies pressure to the adjusting plate 120, so that the adjusting plate 120 and the housing 110 work together to clamp and fix the battery.

[0042] In summary, the battery test fixture 100 can place the battery in the receiving space of the housing 110. The adjusting plate 120 and one side of the housing 110 work together to clamp the battery. The adjusting plate 120 is set in the through groove 111 of the housing 110 to reduce the possibility of damage caused by the battery adjusting plate 120 being separated. The through groove 111 of the housing 110 can protect the battery and improve the protection performance during the battery test. The adjusting member 130 can pass through the mounting hole 112 of the housing 110 to adjust the adjusting plate 120 and change the position of the adjusting plate 120 to fix and limit the battery, so as to facilitate subsequent performance testing of the battery. The adjusting plate 120 is provided with a first heat dissipation hole 121 for heat dissipation of the battery, improving the heat dissipation and cooling effect, thereby improving the test effect.

[0043] Example 2

[0044] refer to Figures 1 to 3 As shown, an embodiment of this application provides another battery test fixture 100, which includes a housing 110, an adjustment plate 120, and an adjustment member 130.

[0045] Specifically, in combination Figure 1 and Figure 2 As shown, a mounting hole 112 and a through groove 111 are provided on one side of the housing 110; an adjusting plate 120 is disposed in the through groove 111, and the adjusting plate 120 and the side of the housing 110 away from the mounting hole 112 define a receiving space for accommodating the battery. The adjusting plate 120 is provided with a plurality of first heat dissipation holes 121; an adjusting member 130 passes through the mounting hole 112, and one end of the adjusting member 130 is connected to the adjusting plate 120 so that the adjusting member 130 can drive the adjusting plate 120 to move and place the battery in the receiving space of the housing 110. The adjusting plate 120 and one side of the housing 110 work together to clamp the battery.

[0046] In this embodiment, the adjustment plate 120 is disposed in the through groove 111 of the housing 110 to reduce the damage caused by the separation of the battery adjustment plate 120. The through groove 111 of the housing 110 can protect the battery and improve the protection performance during battery testing. The adjustment member 130 can pass through the mounting hole 112 of the housing 110 to adjust the adjustment plate 120 and change the position of the adjustment plate 120, thereby fixing and limiting the battery to facilitate subsequent performance testing of the battery. The adjustment plate 120 is provided with a first heat dissipation hole 121 for heat dissipation of the battery.

[0047] Combination Figures 1 to 3As shown, the battery test fixture 100 has a first direction Z, a second direction X, and a third direction Y, wherein the first direction Z, the second direction X, and the third direction Y are arranged perpendicularly to each other. For example, the first direction Z refers to the height direction of the battery test fixture 100, the second direction X refers to the length direction of the battery test fixture 100, and the third direction Y refers to the width direction of the battery test fixture 100. It is understood that the above definitions are only for ease of understanding the relative positional relationships of the various parts of the battery test fixture 100 and should not be construed as limitations on this application.

[0048] In one embodiment, alternatively, referencing Figure 1 and Figure 3 As shown, the housing 110 has a plurality of second heat dissipation holes 113 on the side away from the mounting hole 112. The second heat dissipation holes 113 are arranged opposite to the first heat dissipation holes 121. The second heat dissipation holes 113 of the housing 110 and the first heat dissipation holes 121 of the adjustment plate 120 work together to dissipate heat and cool the battery, improving heat dissipation efficiency and achieving better heat dissipation effect. Optionally, as Figure 1 As shown, the plurality of first heat dissipation holes 121 are arranged in an m*n array structure, and the plurality of second heat dissipation holes 113 are arranged in an m*n array structure, where n≥2 and m≥2. Correspondingly, the plurality of first heat dissipation holes 121 are arranged in an array structure, and the plurality of second heat dissipation holes 113 are arranged in an array structure. The array structure arrangement includes, but is not limited to, staggered arrangement, honeycomb arrangement, directional arrangement, or the array structure arrangement can also be random arrangement, so as to promote air circulation and heat exchange and improve heat dissipation efficiency.

[0049] In one embodiment, alternatively, referencing Figure 1 and Figure 3 As shown, there are multiple adjusting members 130, which are respectively located around the perimeter of the housing 110. Correspondingly, the adjusting members 130 are located around the perimeter of the housing 110. The position of the adjusting plate 120 is adjusted by the multiple adjusting members 130, which drives the adjusting plate 120 to move. The battery is clamped and fixed by the adjusting plate 120 abutting against one side of the battery. At this time, the adjusting plate 120 is located between the adjusting members 130 and the battery. That is, the adjusting members 130, the adjusting plate 120 and the battery are arranged sequentially along the first direction Z, which reduces the possibility of battery misalignment and movement.

[0050] Optionally, combined Figure 1 and Figure 2As shown, the adjusting member 130 is an adjusting bolt. The adjusting bolt can pass through the mounting hole 112 and be screwed to the hole wall of the mounting hole 112. Correspondingly, the adjusting bolt passes through the mounting hole 112 and can be adjusted through the hole wall of the mounting hole 112. The adjusting bolt abuts against the adjusting plate 120. When the battery is clamped on the side of the adjusting plate 120 away from the adjusting bolt, the adjusting bolt abuts against the adjusting plate 120 and applies pressure to the adjusting plate 120 along the first direction Z, so that the adjusting plate 120 and the housing 110 work together to clamp and fix the battery.

[0051] In one embodiment, alternatively, such as Figure 1 and Figure 3 As shown, the adjusting member 130 can drive the adjusting plate 120 to move in the through groove 111 along the first direction Z. That is, the adjusting member 130 abuts against the adjusting plate 120 and drives the adjusting plate 120 to move along the first direction Z. The adjusting member 130 and the adjusting plate 120 can also be connected by a hinge. In this case, the adjusting member 130 can drive the adjusting plate 120 to move in the through groove 111 along the height direction of the battery test fixture 100, so as to achieve the purpose of adjusting the height of the adjusting plate 120 by adjusting the adjusting member 130, which has a better technical effect.

[0052] In related technologies, there are technical problems of excessive and uneven pressure between the regulating plate 120 and the battery, which causes the internal components such as the electrode plates or separators of the battery to be squeezed during the battery cycle charge and discharge test, affecting the normal charge and discharge process of the battery.

[0053] In one embodiment, alternatively, referencing Figure 1 and Figure 2 As shown, a scale 140 is provided at the opening of the housing 110 near the through groove 111 to display the position of the adjustment plate 120 and the height of the battery. According to the size and shape of the battery, the position of the adjustment plate 120 can be precisely adjusted by observing the scale 140, thereby reducing the pressure on the battery casing and preventing the battery casing from collapsing or deforming due to excessive force, and ensuring that the battery is not damaged when clamped and fixed during the test.

[0054] In one embodiment, optionally, the projected area of ​​the adjusting plate 120 along the first direction Z is S1, and the projected area of ​​the side of the housing 110 near the mounting hole 112 on the adjusting plate 120 is S2, satisfying: 0.5S1≤S2≤S1, that is, the projected area S2 of the housing 110 on the adjusting plate 120 is less than or equal to the projected area S1 of the adjusting plate 120 in the height direction of the battery test fixture 100. For example, S2 is 0.50m. 2 S1 is 0.50m 2This ensures that the adjusting plate 120 has sufficient area to clamp and fix the battery, increasing the contact area between the battery and the adjusting plate 120. Additionally, S2 can be set to 0.25m. 2 The projected area S2 of the housing 110 on the adjusting plate 120 is made greater than or equal to 0.5S1. This ensures sufficient contact area between the battery and the adjusting plate 120 while reducing the weight of the housing 110 and improving its heat dissipation performance. It also promotes gas flow and heat exchange, allowing heat generated during battery testing to dissipate promptly and improving heat dissipation. Of course, the dimensions of S1 and S2 are not limited to this. In other embodiments, when S1 is 0.60 μm... 2 At that time, S1 can also be 0.30m 2 When S2 is 0.70m 2 At that time, S1 can also be 0.35m 2 0.45m 2 0.50m 2 0.55m 2 0.60m 2 0.70m 2 And so on, which will not be listed and explained one by one here.

[0055] Alternatively, as Figure 1 As shown, the housing 110 has an opening 114 on the side near the mounting hole 112. The opening 114 is arranged opposite to the adjustment plate 120. The opening 114 of the housing 110 facilitates ventilation and heat dissipation of the housing 110, improves the heat dissipation effect during battery testing, and also reduces the overall weight of the housing 110, making the housing 110 lightweight and saving the amount of raw materials used in the housing 110.

[0057] The present invention also provides a testing system, including the battery testing fixture 100 in embodiment 1 or embodiment 2. The testing system including the battery testing fixture 100 has all the beneficial effects of the battery testing fixture 100, which will not be described in detail here.

[0058] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0059] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
