Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0022] According to one embodiment of the present invention, in conjunction with the appended drawings Figures 1-4 As shown.

[0023] A dual-terminal electrode cell DCR testing device includes a fixing plate 9, a housing 14 connected to the upper surface of the fixing plate 9, a telescopic mechanism 7 connected to the inner side wall of the housing 14, a positioning mechanism 1 connected to the upper surface of the housing 14, a test body 6 connected to the upper surface of the fixing plate 9, a support block 10 connected to the upper surface of the fixing plate 9, a first test head 2 connected to the upper surface of the fixing plate 9, a second test head 15 provided above the fixing plate 9, and a tool box 13 connected to the upper surface of the fixing plate 9.

[0024] In this embodiment, the telescopic mechanism 7 includes a slide rod 701 connected to the housing 14. A slide cylinder 702 is slidably connected to the outer surface of the slide rod 701. A slide plate 704 is connected to the outer surface of the slide cylinder 702. A tension spring 703 is sleeved on the outer surface of the slide rod 701. The left end of the tension spring 703 is connected to the right side of the slide plate 704. The right end of the tension spring 703 is connected to the inner sidewall of the housing 14. The front of the slide plate 704 is connected to the back of the second test head 15. The tension provided by the tension spring 703 facilitates the sliding of the slide plate 704 inside the housing 14 and allows the slide cylinder 702 to follow the movement on the surface of the slide rod 701. At the same time, it is beneficial for the slide plate 704 to drive the second test head 15 to move.

[0025] In this embodiment, the positioning mechanism 1 includes a vertical plate 101 connected to the housing 14. A connecting plate 102 is connected to the front of the vertical plate 101. An electric push rod 103 is embedded on the upper surface of the connecting plate 102. A pressure pad 104 is connected to the bottom end of the electric push rod 103. The pushing force of the electric push rod 103 facilitates pushing the pressure pad 104 closer to the battery cell. At the same time, it is beneficial for the pressure pad 104 to apply pressure and position the battery cell. A pull rope 16 is provided above the fixing plate 9. The right end of the pull rope 16 is connected to the left side of the second test head 15. A pull ring 17 is connected to the left end of the pull rope 16. The cooperation of the pull ring 17 and the pull rope 16 facilitates moving the second test head 15 to the left.

[0026] In this embodiment, the bottom surface of the fixing plate 9 is connected to the mounting plate 8. Each mounting plate 8 has two through holes 12 on its bottom surface. The design of the through holes 12 and the mounting plate 8 makes it easy to install the device in the usage position. A set of heat dissipation vents 5 are provided on the right side of the test body 6. A fan 3 is embedded on the upper surface of the test body 6. The design of the heat dissipation vents 5 and the fan 3 facilitates heat dissipation. A display plate 4 is provided above the fixing plate 9. The left side of the display plate 4 is connected to the right side of the test body 6. The display plate 4 helps the staff understand the operation process of the device. Two reinforcing blocks 11 are connected to the bottom surface of the fixing plate 9. The side of the two reinforcing blocks 11 that is far apart from each other is connected to the side of the two mounting plates 8 that is close to each other. The design of the reinforcing blocks 11 makes it easier to connect the mounting plate 8 and the fixing plate 9 more firmly.

[0027] Working principle: During testing, the operator first pulls the pull ring 17, which in turn moves the second test head 15 to the left via the pull rope 16. At this time, the second test head 15 causes the slide plate 704 to slide inside the housing 14, while simultaneously stretching the tension spring 703. Then, the double-sided terminal post battery cell to be tested is placed on the support block 10, so that its position corresponds to the first test head 2 and the second test head 15.

[0028] Then, the pull ring 17 is released. Under the tension of the tension spring 703, the slide plate 704 drives the slide cylinder 702 to slide to the right on the slide rod 701, thereby causing the second test head 15 to move to the right and contact one side of the battery cell. At the same time, the first test head 2 contacts the other side of the battery cell. Subsequently, the positioning mechanism 1 starts to work. The connecting plate 102 on the upright plate 101 fixes the electric push rod 103. The electric push rod 103 extends and pushes the pressure pad 104 downward until the pressure pad 104 contacts the upper surface of the battery cell, completing the positioning of the battery cell and preventing the battery cell from shifting during the test. At this time, the test body 6 performs DCR test on the battery cell through the first test head 2 and the second test head 15.

[0029] During the test, the fan 3 and the heat dissipation port 5 work together to dissipate heat from the test body 6, preventing it from being affected by excessive temperature and thus affecting the test accuracy and service life. In addition, the tools required for the test can be stored in the tool box 13 for easy access and management.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
