In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0034] In the process of injecting potting glue into the battery, the performance evaluation of the potting glue is limited to the viscosity of the potting glue itself. The potting effect of the potting glue needs to be verified during the potting process of the actual product, which not only reduces the efficiency of the potting glue performance test, but also fails to accurately compare the performance of different types of potting glue, resulting in the inability to guide the selection of suitable potting glue. In addition, verifying the potting effect of the potting glue during the actual product processing process also greatly increases the investment of resources.

[0035] In order to solve the above problems, Figure 1 to Figure 3 As shown, this embodiment provides a potting glue performance test tool, which is used to test the performance of the potting glue during potting. Specifically, the potting glue performance test tool includes a contoured battery case 1, a plurality of contoured liquid cooling plates 2, and a plurality of contoured battery cells 3, wherein the contoured battery case 1 has a receiving cavity 11, and the contoured battery case 1 is provided with a potting glue injection port 12 connected to the receiving cavity 11, a plurality of contoured liquid cooling plates 2 are arranged at intervals in the receiving cavity 11, and a potting glue flow channel 13 is formed between the bottom of the contoured liquid cooling plate 2 and the bottom wall of the contoured battery case 1, a plurality of contoured battery cells 3 are arranged in sequence in the receiving cavity 11, and each contoured battery cell 3 can fit with the corresponding contoured liquid cooling plate 2. In this embodiment, the contoured battery case 1 truly simulates the structure of the battery case, the contoured liquid cooling plate 2 truly simulates the structure of the liquid cooling plate, and the contoured battery cell 3 truly simulates the structure of the battery cell, so that the entire potting glue performance test tool simulates the composition structure of the battery, and the injected potting glue can be gradually filled into the entire accommodating cavity 11 through the potting glue injection port 12 and the potting glue flow channel 13, thereby accurately simulating the process of filling the battery with potting glue, and realizing the performance test of different types of potting glue during potting, thereby accurately comparing the performance of different types of potting glue, guiding the selection of appropriate potting glue, and also improving the efficiency of potting glue performance testing. In addition, the performance test of the potting glue during potting by the potting glue performance test tool reduces the input of resources.

[0036] It should be noted that by accurately simulating the process of filling batteries with potting glue through the potting glue performance test tooling, the feasibility of potting with various types of potting glue can be understood, the time and efficiency of potting glue can be tested in advance, and the appropriate potting glue and related dimensions of the battery can be adjusted and designed under the required potting efficiency.

[0037] Preferably, in this embodiment, the shaped battery cell 3 can be made of aluminum or copper, so that the shaped battery cell 3 is aligned with the actual battery cell material, thereby eliminating the influence of the interface of different materials on the fluidity of the potting compound, better simulating the actual process of filling the potting compound, and improving the accuracy and reliability of the potting compound test.

[0038] In this embodiment, if Figure 1 and Figure 2 As shown, the side wall of the contoured battery case 1 is expanded outward to form a potting glue injection port 12. The structural design of the potting glue injection port 12 not only facilitates the injection of potting glue into the accommodating cavity 11 of the contoured battery case 1, but also improves the structural strength and structural stability of the contoured battery case 1.

[0039] In an optional embodiment, if Figure 1 and Figure 2 As shown, the cross section of the potting glue injection port 12 is arc-shaped. The shape of the potting glue injection port 12 makes the appearance of the entire contoured battery box 1 more beautiful, and further ensures the structural strength and structural stability of the contoured battery box 1.

[0040] In this embodiment, if Figure 2 As shown, a plurality of positioning grooves 14 are provided at intervals on the bottom wall of the contoured battery case 1, and a contoured battery cell 3 is positioned in each positioning groove 14. The structural design of the positioning grooves 14 realizes the positioning effect of the contoured battery cell 3 in the contoured battery case 1, and ensures that the contoured battery cell 3 is accurately placed in a suitable position in the accommodating cavity 11.

[0041] In this embodiment, if Figure 1 and Figure 2 As shown, the two opposite side walls of the contoured battery case 1 are provided with snap-in grooves 15, and the two ends of the contoured liquid cooling plate 2 are respectively snap-in fixed with the snap-in grooves 15 on both sides, thereby realizing the installation and fixation of the contoured liquid cooling plate 2 on the contoured battery case 1. In addition, the snap-in fixation of the contoured liquid cooling plate 2 by the snap-in grooves 15 not only has a simple structure, but also facilitates the installation and removal of the contoured liquid cooling plate 2 on the contoured battery case 1.

[0042] Preferably, in this embodiment, the contoured liquid cooling plate 2 includes a main plate portion 22 and a clamping plate portion 21, wherein the main plate portion 22 is located in the accommodating cavity 11 and is used to fit with the contoured battery cell 3, and both ends of the main plate portion 22 are connected with the clamping plate portion 21, and the clamping plate portion 21 is used to clamp and fix with the clamping groove 15 on the corresponding side. In this embodiment, the main plate portion 22 of the contoured liquid cooling plate 2 is serpentine, so as to more reliably simulate the structure of the real liquid cooling plate and improve the accuracy and reliability of the potting glue test.

[0043] In this embodiment, if Figure 1 and Figure 2 As shown, the clamping groove 15 is an open long groove, and the open long groove extends along the height direction of the contoured battery cell 3. The structural design of the clamping groove 15 is such that when the contoured liquid cooling plate 2 and the contoured battery case 1 need to be installed, the clamping plate portion 21 can be directly inserted into the clamping groove 15 from top to bottom. When the contoured liquid cooling plate 2 needs to be removed from the contoured battery case 1, the contoured liquid cooling plate 2 can be directly pulled out of the clamping groove 15 upward. In addition, the structural design of the clamping groove 15 increases the clamping area of ​​the clamping groove 15 and the clamping plate portion 21, thereby ensuring the stability of the clamping and fixing of the clamping groove 15 to the clamping plate portion 21.

[0044] In this embodiment, the width of the opening long groove is matched with the thickness of the clamping plate 21, which improves the tightness of the clamping between the opening long groove and the clamping plate 21 and further improves the stability of the clamping and fixing of the clamping groove 15 to the clamping plate 21.

[0045] Preferably, in this embodiment, the height dimension of the potting glue flow channel 13 formed between the bottom of the contoured liquid cooling plate 2 and the bottom wall of the contoured battery box 1 is adjustable, thereby simulating the influence of the potting glue flow channels 13 of different heights on the fluidity of the potting glue, thereby guiding the height design of the potting glue flow channel 13 in the actual product.

[0046] In this embodiment, the potting glue performance test tool also includes a plurality of adjustment pads (not shown in the figure), and a corresponding number of adjustment pads can be selectively provided between the bottom of the contoured liquid cooling plate 2 and the bottom wall of the open long groove, so as to adjust the height dimension of the potting glue flow channel 13. Specifically, when it is necessary to increase the height dimension of the potting glue flow channel 13, the number of adjustment pads between the bottom of the contoured liquid cooling plate 2 and the bottom wall of the open long groove can be increased, and when it is necessary to reduce the height dimension of the potting glue flow channel 13, the number of adjustment pads between the bottom of the contoured liquid cooling plate 2 and the bottom wall of the open long groove can be reduced. It should be noted that in other embodiments, open long grooves with different extension lengths can also be designed to meet the design of potting glue flow channels 13 with different height dimensions.

[0047] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
