[0028] See also Figures 1 to 5 , Figure 1 It is a three-dimensional schematic diagram of a CCS electrical performance test device provided by an embodiment of the utility model. Figure 2 yes Figure 1 The front view schematic diagram of the CCS electrical performance test device shown in the figure, Figure 3 is a three-dimensional schematic diagram of a CCS assembly 30 placed on a test mechanism 12, Figure 4 yes Figure 3 Schematic diagram of the explosion, Figure 5 yes Figure 4An enlarged schematic diagram of the A area in the figure. In order to achieve at least one of the above advantages or other advantages, an embodiment of the utility model provides a CCS electrical performance test device. As shown in the figure, the CCS electrical performance test device may include at least a frame 10, a test mechanism 12 and a lifting mechanism 14. The frame 10 has a work surface 101 for placing other equipment.
[0029] The test mechanism 12 is arranged on the work surface 101 of the frame 10, and is used to test the electrical performance of the CCS component 30. The test mechanism 12 is used to place the CCS component 30, and the placed CCS component 30 includes an aluminum bar 32. The test mechanism 12 includes an elastic probe 121 and a base plate structure 122. The elastic probe 121 is arranged on the base plate structure 122, and the number of the elastic probes 121 can be multiple, which can be set according to actual needs. The base plate structure 122 has a hole 124, and the elastic probe 121 passes through the hole 124 so as to contact the aluminum bar 32 of the CCS component 30 through the hole 124. The CCS component 30 will be placed on the surface of the base plate structure 122 later and its aluminum bar 32 will contact the elastic probe 121. In actual work, the elastic probe 121 is located at the bottom and does not move, and the CCS component 30 is placed on the test mechanism 12. At this time, the elastic probe 121 is not completely in close contact with the aluminum bar 32 of the CCS component 30; the aluminum bar 32 of the CCS component 30 is pressed down by the lifting mechanism 14, so that the aluminum bar 32 is in close contact with the elastic probe 121, and the electrical test is completed. In the whole process, since the CCS component 30 is positioned on the bottom plate structure 122, it can effectively avoid the traditional mode. The situation that may occur during the movement is offset, resulting in problems such as inaccurate test performance.
[0030] In some embodiments, the surface of the elastic probe 121 is plated with metal, and the metal includes gold, to improve electrical test performance.
[0031] The CCS assembly 30 also includes an isolation plate 34. The isolation plate 34 is connected to the aluminum bar 32. As shown in the figure, a plurality of aluminum bars 32 are distributed on both sides of the isolation plate 34. In the CCS assembly 30 currently used for storage batteries, the bottom of the isolation plate 34 protrudes from the bottom of the aluminum bar 32 to form a high and low step. The bottom plate structure 122 includes a first bottom plate 1221 and a second bottom plate 1222. The first bottom plate 1221 is connected to the second bottom plate 1222. The hole 124 is located on the second bottom plate 1222. The height of the second bottom plate 1222 is higher than the first bottom plate 1221. In other words, the second bottom plate 1222 protrudes from the first bottom plate 1221, and the height difference between the two is basically the height of the second bottom plate 1222 itself. By means of the height difference between the first bottom plate 1221 and the second bottom plate 1222, a receiving space is formed between the first bottom plate 1221 and the second bottom plate 1222 for placing the isolation plate 34. When the lifting mechanism 14 presses down the CCS assembly 30, the aluminum bar 32 contacts the second bottom plate 1222, and the isolation plate 34 protruding from the aluminum bar 32 is in the receiving space formed between the first bottom plate 1221 and the second bottom plate 1222 to avoid damage. Compared with the traditional plane design, this embodiment can ensure that the elastic probe 121 is pressed by the same tool, ensure that the elastic variables are consistent, and avoid inaccurate measurement.
[0032] The lifting mechanism 14 is disposed above the testing mechanism 12. The lifting mechanism 14 has a lifting function, and can press down the CCS assembly 30 so that the aluminum bar 32 is in good contact with the elastic measuring needle 121. In some embodiments, the lifting mechanism 14 includes an elastic pressure rod 141, and the elastic pressure rod 141 is used to press down the CCS assembly. Due to the influence of process conditions, the initial heights of the various pressure rods are not absolutely the same, and the degree of downward pressure driven by the lifting mechanism 14 is the same. Therefore, the elastic pressure rod 141 is used to avoid damage caused by excessive downward pressure.
[0033] In some embodiments, the test mechanism 12 is detachably mounted on the rack 10. By replacing the test fixture of the test mechanism 12, the electrical performance of multiple types of CCS components 30 can be tested by one machine, and the replacement is simple and fast.
[0034] In some embodiments, the CCS electrical performance test device further includes a display screen 16, an operation panel 18, a test instrument 20, and an electrical cabinet 22, and the display screen 16, the operation panel 18, the test instrument 20, and the electrical cabinet 22 are all arranged in the frame 10. The test mechanism 12 can be connected to the test instrument 20 through an external test connection line (the test connection line is not shown in the figure), and the test mechanism 12 is controlled by the test instrument 20 to perform the CCS electrical test. The test result data can be synchronously stored in the electrical cabinet 22.
[0035] In summary, a CCS electrical performance test device provided by an embodiment of the present invention can effectively improve the test accuracy of the CCS electrical performance test device and avoid damage to the CCS component 30 through the matching arrangement of the test mechanism 12 and the lifting mechanism 14 .

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
