Description

Technical Field

[0001] The present invention relates to the technical field of new energy battery testing, and in particular to a battery cell pole dynamic load testing device. Background Art

[0002] The battery pole is an important component of the battery cell. Its main function is to connect the positive and negative poles of the battery with the external circuit to form a loop and overload current. The quality and performance of the battery pole directly affect the safety and performance stability of the battery. In order to ensure the reliability of the battery pole, it is necessary to test the maximum dynamic force. The dynamic force test is to simulate the use in the actual scene, detect the battery pole under the action of external force, and verify its performance and stability, such as pole breakage, looseness, failure, etc. However, in the existing dynamic load test of the battery pole, dynamic force tests are often performed in the horizontal and vertical directions. In the actual application scenario, forces are usually received from multiple angles, resulting in poor simulation effects of the existing dynamic load test, thereby affecting the test reliability of the battery cell. In addition, in the existing battery dynamic load test process, the tester is usually required to control the dynamic force test, which requires the tester to be close to the battery cell, which is not only time-consuming and labor-intensive, but also has high labor costs.

[0042] Working principle: When the present invention is in use, the test battery cell 504 is inserted between the two buffer layers 503, and then the buffer layer 503 is clamped by the battery cell fixing fixture 502, so that the test battery cell 504 is fixed on the fixing seat 501, and then the fixing seat 501 is fixed on the fixing platform 406 by the tiger clamp 506, and the translation screw 407 is driven to rotate by the rotation position adjustment hand wheel 408. When the translation screw 407 rotates, it drives the translation block 409 to move in the direction away from the translation guide rail 401, and then the movable support block 403 is driven to translate by the translation block 409. The movable support block 403 drives the second support frame 405 to move, so that the first support frame 404 rotates, so that the height of the fixed platform 406 decreases, and the distance from the support column 201 decreases. When the movable support block 403 moves, it drives the fixed sleeve 410 to move at the same time, and the fixed pressure plate 411 is fixed to the installation base plate 1 by making the fixed pressure plate 411 follow the position of the fixed sleeve 410 on the installation base plate 1, so that the fixed sleeve 410 is stably fixed on the top of the installation base plate 1 to avoid shaking during testing, and the fixed pressure plate 411 is prevented from loosening by the limit block 412;

[0043] By rotating the height adjustment hand wheel 211, the lifting screw 210 is driven to rotate. When the lifting screw 210 rotates, the lifting block 212 is driven to move on the lifting screw 210, and the lifting plate 206 is driven to be lifted and lowered by the lifting block 212. The lifting slider 205 follows the lifting plate 206 and is lifted and lowered on the lifting guide rail 204 at the same time, so that the movement states of the two ends of the lifting plate 206 are synchronized. After adjusting to the required height, the lifting plate 206 is fixed on the limit groove 207 by the height fixing rod 213, so that the lifting plate 206 is fixed, and the slider fixing screw 214 is rotated to make the slider fixing screw 214 press against the limit plate 203, so that the lifting block 212 is fixed, so that the height of the servo pressure control device 308 is fixed;

[0044] Then, according to the angle required for the test, the angle of the servo pressure control device 308 toward the pole of the test cell 504 is adjusted, and the servo pressure control device 308 is rotated on the rotating shaft 302 by the auxiliary handle 307 following the support seat 304 through the rotating seat 303. After rotating to the required angle, the angle fixing rod 305 is pressed against the rotating seat 303 by rotating the angle adjustment handle 306, so that the angle of the servo pressure control device 308 is fixed;

[0045] The push rod 309 is driven to move by the servo pressure control device 308, so that the push plate 311 moves following the push rod 309, and the push plate 311 is stably moved by the test guide slide bar 310, and then the first connecting frame 312 is driven to move by the push plate 311, and the tension sensor 313 is driven to apply tension or pressure by the first connecting frame 312, and the test pressure head 314 is connected through the tension sensor 313, so that the test pressure head 314 can apply tension or pressure to the pole connecting seat 505 through the second connecting frame 315, and finally, the pole of the test battery 504 is applied with tension or pressure through the pole connecting seat 505, so as to simulate the use of the pole of the test battery 504, so as to test it;

[0046] When the height of the fixed platform 406 is at the highest, the servo pressure control device 308 is horizontal with the pole of the test battery cell 504. When the height of the fixed platform 406 is at the lowest, the servo pressure control device 308 is vertical with the pole of the test battery cell 504. During the test, without a clamp, a pulling force is applied to the positive pole in the +Z direction, and 0N to 50N to 0N is achieved within 1s. This process is repeated 16,000 times, and then the tests in the -Z, +X, -X, +Y, and -Y directions are completed in turn. Similarly, this process is repeated for the negative pole. In addition, the height of the test battery cell 504 can be adjusted as needed. After adjusting the test angle of the servo pressure control device 308 accordingly, multi-angle testing can be performed. During the test, any abnormalities such as leakage, weld cracking, pole falling off, etc. must be promptly fed back and the test stopped.
