Description

Technical Field

[0001] This invention relates to the field of battery testing technology, and more specifically, to a multi-temperature zone high and low temperature test chamber for batteries. Background Technology

[0002] With the continuous development of new energy technologies, batteries, as the core component of energy storage and electric vehicle driving force, have become a key focus of research and industrial attention in terms of performance and lifespan. Battery aging is closely related to factors such as its operating environment, temperature, vibration, and external forces. Traditional battery life testing methods mainly rely on battery charge-discharge tests under static conditions or placing the battery in a constant-temperature and temperature-controlled device for charge-discharge tests.

[0003] A multi-temperature zone high and low temperature test chamber for batteries is a device used to test the performance of batteries under different temperature environments. This test chamber can simulate the working state of batteries under extreme high and low temperature conditions to evaluate their safety, stability and reliability, and determine the degree of battery aging to determine whether the battery can still be used.

[0004] Existing multi-temperature zone high and low temperature test chambers for batteries are mainly used to simulate the working environment of batteries under different temperature conditions, but they usually ignore the mechanical stresses such as vibration and impact encountered by batteries in actual use. Traditional multi-temperature zone high and low temperature test chambers for batteries can only test the performance of batteries under static conditions and do not consider the performance degradation of batteries under motion and vibration conditions. In addition, existing equipment mostly relies on the battery's electrical performance data (such as voltage, current, capacity, etc.) to assess its aging, while lacking stability testing of the battery casing and internal structure, resulting in the inability to accurately assess the aging process of batteries in complex environments. Therefore, we designed a multi-temperature zone high and low temperature test chamber for batteries. Summary of the Invention

The discharge detector is connected to the battery body through a wire.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. The multi-temperature zone high and low temperature test chamber for batteries described in this invention can detect the aging of the battery body under different temperature conditions using a variable temperature chamber and a discharge detector. Furthermore, by controlling the gas flow through an air pump, the power generated by the gas delivery causes the connecting shaft and counterweight to rotate continuously. Under the action of the counterweight, the connecting plate and the battery body fixed to the connecting plate vibrate. The data obtained can be compared with the data from the static testing of the battery body to obtain more accurate data. Through the vibration test under power, the impact of these changes on the battery body performance can also be monitored in real time, especially on parameters such as battery capacity, internal resistance, and temperature. This helps to further predict the aging of the battery body, assess battery life, and promptly identify potential safety risks. Moreover, the vibration also generates certain stress on the overall structure of the battery body, detecting microscopic damage or component loosening that could lead to the battery's aging.

[0017] 2. The multi-temperature zone high and low temperature test chamber for batteries described in this invention, through the continuous vibration of the connecting plate, not only drives the battery body to vibrate, but also causes the impact plate to rotate continuously. As the battery body vibrates, it impacts the impact plate, and the mutual collision between the two can detect the aging of the battery body's outer shell. Furthermore, due to the rotation of the impact plate, a rotational pulling force is generated, changing the direction of the force exerted by the impact plate on the battery body, thereby further detecting the degree of aging of the battery shell. During the rotation of the impact plate, the second threaded plate will also continuously move up and down, and the position of the impact plate can be controlled by the second threaded plate. In this way, the impact distance between the impact plate and the battery body will continuously change, and different distances will have different impact effects, thereby further detecting the degree of aging of the battery body.

[0018] 3. The multi-temperature zone high and low temperature test chamber for batteries described in this invention uses an air pump to rotate the first rotating shaft. This first rotating shaft, while driving the counterweight to rotate, also drives the convex block to rotate. The rotation of the convex block, in conjunction with a second spring, causes the piston to continuously move inside the fixed box. This allows the piston to continuously draw in and release gas through a second connecting pipe, causing the gas pressure inside the air turntable to fluctuate. This fluctuation in pressure causes the hollow turntable to rotate at varying speeds, which in turn causes the counterweight to rotate at varying speeds. Ultimately, this causes the connecting plate to vibrate the battery body at varying frequencies, allowing the battery body to be used in multiple ways. Furthermore, the vibration frequency also affects the rotation speed of the impact plate, altering the impact effect between the impact plate and the battery body, thus further testing the battery body for aging.

Detailed Implementation

[0031] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0032] like Figures 1 to 6 As shown in the figure, a multi-temperature zone high and low temperature test chamber for batteries according to an embodiment of the present invention includes a variable temperature chamber 1. The variable temperature chamber 1 is provided with a vibration testing mechanism. The vibration testing mechanism includes a second fixed plate 502. A first sliding groove is provided through the second fixed plate 502. A sliding plate 503 is slidably connected inside the first sliding groove. The top and bottom of the sliding plate 503 are connected to the second fixed plate 502 by a first spring 505. A first rotating shaft 504 is rotatably connected to the sliding plate 503. A first reciprocating screw 507 is fixedly connected to the opposite ends of the two first rotating shafts 504. The two first reciprocating screws 507 are connected by a connecting shaft 508. A counterweight 509 is fixedly connected to the connecting shaft 508. A connecting plate 506 is fixedly connected between the two sliding plates 503. A placement mechanism is provided on the connecting plate 506. A battery body 3 is provided inside the placement mechanism. The placement mechanism is used to fix the battery body 3 on the connecting plate 506.

[0033] Please refer to Figure 2 , Figure 4 , Figure 5 The placement mechanism includes a placement frame 701, which is located below the connecting plate 506, and the battery is located inside the placement frame 701. A screw 702 is fixedly connected to the placement frame 701, which passes through the connecting plate 506 and extends above the connecting plate 506. A threaded ring 704 is threadedly connected to the screw 702, and multiple retaining teeth 703 are fixedly connected to the threaded ring 704.

[0034] Rotate the threaded ring 704 to disengage it from the screw 702, allowing the placement bracket 701 to be removed from the connecting plate 506. Then, place the battery body 3 inside the removed placement bracket 701 and repeat the disassembly process to fix the placement bracket 701 back onto the connecting plate 506. Once the battery body 3 is fixed, connect the discharge detector 2 to the battery body 3 via wires. After the wires are connected, the aging condition of the battery body 3 can be detected. Furthermore, by controlling the temperature chamber 1 and changing the internal temperature of the temperature chamber 1, the aging condition of the battery body 3 can be further detected.

[0035] Please refer to Figures 2 to 4A drive mechanism is fixedly connected to the first rotating shaft 504. The drive mechanism rotates via a drive connecting shaft 508 and a counterweight 509. The drive mechanism includes an air pump 401. A telescopic hose 402 is fixedly installed at the air outlet of the air pump 401. A first connecting pipe 403 is fixedly connected to the bottom of the telescopic hose 402. A rotating pipe 405 is rotatably connected to the first connecting pipe 403. A hollow turntable 406 is fixedly connected to the rotating pipe 405. Multiple bent pipes 407 are fixedly connected to the hollow turntable 406. The hollow turntable 406 is fixedly connected to the first rotating shaft 504. Two second fixing plates 502 are connected to each other through a first fixing plate 501. The first fixing plate 501 is fixedly connected to the temperature box 1. A discharge detector 2 is fixedly connected to the bottom of the first fixing plate 501. The discharge detector 2 is connected to the battery body 3 through a wire.

[0036] When the air pump 401 is started, it draws gas and delivers it to the first connecting pipe 403. The gas in the first connecting pipe 403 enters the hollow turntable 406 and rotates. Due to the action of the bend in the pipe 407, the ejected gas has a reaction force, causing the hollow turntable 406 to rotate. The rotation of the hollow turntable 406 drives the first rotating shaft 504 to rotate, which in turn drives the first reciprocating screw 507 to rotate. The rotation of the first reciprocating screw 507 drives the connecting shaft 508 to rotate, which in turn drives the counterweight 509 to rotate. During the rotation of the counterweight 509, the sliding plate 503 continuously rotates. The first spring 505 causes the battery to vibrate up and down, which in turn causes the connecting plate 506, connected to the slide plate 503, to vibrate up and down. The battery body 3, fixed to the connecting plate 506, also vibrates up and down. This allows the battery body 3 to undergo aging testing while vibrating up and down. The data obtained can be compared with the data from the static testing of the battery body 3 to obtain more accurate data. The vibration of the battery body 3 also causes the internal components, such as the electrolyte, and the external casing to vibrate. This vibration may lead to physical changes in the internal materials, such as electrolyte flow and the formation of microcracks. Furthermore, during the up and down vibration of the battery body 3, it will also collide with the impact plate 906. During the impact, it can detect whether the outer casing of the battery body 3 has aged, and it can also intensify the vibration of the internal structure of the battery body 3, detecting whether the internal structure has become unstable due to aging.

[0037] like Figures 9 to 10 As shown, a scraping and impact mechanism is fixedly connected to the bottom of the connecting plate 506;

[0038] The scraping and impact mechanism includes connecting columns 907, two connecting columns 907 are connected by a drive plate 902, a rotating column 904 is provided inside the connecting plate 906, the rotating column 904 is rotatably connected to the temperature box 1, a track groove 905 is provided on the rotating column 904, a drive column 901 is provided inside the track groove 905, and the drive column 901 is fixedly connected to the drive plate 902; an extension column 903 is slidably connected to the rotating column 904, and an impact plate 906 is fixedly connected to the top of the extension column 903.

[0039] It should be noted that during the up-and-down vibration of the connecting plate 506, it will also drive the connecting column 907 to vibrate up and down. The up-and-down vibration of the connecting column 907 will cause the driving plate 902 and the driving column 901 to move up and down. The up-and-down movement of the driving column 901 will act on the track groove 905 on the rotating column 904, causing the rotating column 904 to rotate clockwise and counterclockwise. The rotation of the rotating column 904 will drive the impact plate 906 to rotate. Since the impact plate 906 will collide with the battery body 3, and the impact plate 906 will generate a pulling force on the battery body 3 while rotating, it will change the direction of the force exerted by the impact plate 906 on the battery body 3, thereby further detecting the aging degree of the battery casing.

[0040] An auxiliary groove is formed through the connecting plate 506, and a lifting mechanism is fixedly connected to the drive column 901. The lifting mechanism includes a second gear 809, which meshes with two transmission components. The transmission components are rotatably connected to the temperature box 1. A second reciprocating screw 801 is fixedly connected to the top of the transmission components. The second reciprocating screw 801 extends into the auxiliary groove and is rotatably connected to the connecting plate 506. A second threaded plate 802 is threaded onto the second reciprocating screw 801. The second threaded plate 802 is located inside the auxiliary groove and is slidably connected to the connecting plate 506. A ball bearing 803 is rolled onto the connecting plate 506. The transmission components include a rotating ring 807, which is rotatably connected to the temperature box 1. A first gear 804 is fixedly connected to the rotating ring 807, and the first gear 804 meshes with the second gear 809. A toothed groove is formed through the first gear 804, and a rotating disk 808 is disposed inside the toothed groove. A lever is fixedly connected to the rotating disk 808. The moving plate 810 and the actuating plate 810 are matched with the toothed groove. A sliding box 806 is fixedly connected to the rotating disk 808. The sliding box 806 is rotatably connected to the temperature chamber 1. A sliding column 805 is slidably connected to the sliding box 806. The sliding column 805 is fixedly connected to the second reciprocating screw 801. During the rotation of the driving column 901, it will also drive the second gear 809 to rotate. The second gear 809 drives the first gear 804 to rotate. The first gear 804 drives the sliding box 806 to rotate through the actuating plate 810. The sliding box 806 drives the sliding column 805 to rotate. The sliding column 805 drives the second reciprocating screw 801 to rotate. The second reciprocating screw 801 will drive the second threaded plate 802 to move up and down. The second threaded plate 802 will lift the impact plate 906, thereby changing the impact distance between the impact plate 906 and the battery body 3. Different distances have different impact effects, thereby further detecting the aging degree of the battery body 3.

[0041] like Figure 2 , Figure 11 As shown, a transformer mechanism is also fixedly connected to the first rotating shaft 504. The transformer mechanism includes a protrusion 601, which is fixedly installed on the first rotating shaft 504. A fixed box 604 is provided below the protrusion 601. The fixed box 604 is fixedly connected to the slide plate 503. A slide rod 606 is provided through the fixed box 604 and is slidably connected to the fixed box 604. A piston 603 is fixedly connected to the slide rod 606. The piston 603 is located inside the fixed box 604 and is slidably connected to the fixed box 604. A second spring 605 is sleeved on the slide rod 606. The two ends of the second spring 605 are respectively connected to the fixed box 604 and the piston 603. A second connecting pipe 602 is fixedly connected to the fixed box 604. A positioning ring 404 is fixedly connected to the second connecting pipe 602. The positioning ring 404 is fixedly connected to the first connecting pipe 403. The second connecting pipe 602 passes through the positioning ring 404 and communicates with the first connecting pipe 403.

[0042] It should be noted that when the first rotating shaft 504 rotates, it also drives the protrusion 601 to rotate. The rotation of the protrusion 601 will squeeze the slide rod 606, causing the slide rod 606 to continuously drive the piston 603 to move. With the help of the second spring 605, the piston 603 can continuously extract or release gas. The extracted or released gas will act on the first connecting pipe 403 through the second connecting pipe 602. In this way, the gas input into the hollow turntable 406 through the first connecting pipe 403 will be sometimes strong and sometimes weak, so that the rotation speed of the first rotating shaft 504 will also be sometimes large and sometimes small. This will cause the vibration frequency on the battery body 3 to change continuously, thereby further detecting the aging degree of the battery body 3.

[0043] like Figures 7 to 8 As shown, a second sliding groove is formed through the connecting plate 506, and a reinforcing mechanism is slidably connected inside the second sliding groove. The reinforcing mechanism includes a first slider 706, which is located inside the second sliding groove and slidably connected to it. A third spring 707 is fixedly connected to the first slider 706, and a second slider 709 is fixedly connected to the third spring 707. The second slider 709 is slidably connected to the connecting plate 506. A first threaded plate 705 is fixedly connected to the first slider 706, and the first threaded plate 705 is threadedly connected to the first reciprocating screw 507. A drive frame 708 is fixedly connected to the top of the second slider 709.

[0044] It should be noted that the rotation of the first reciprocating screw 507 will also drive the first threaded plate 705 to reciprocate. The movement of the first reciprocating screw 507 will compress the third spring 707. The third spring 707 will act on the second slider 709, causing the second slider 709 to drive the drive frame 708 to move. The drive frame 708 is fixedly installed with a locking tooth 703. The locking tooth 703 on the drive frame 708 will act on the locking tooth 703 on the threaded ring 704, further tightening it and preventing it from loosening.

[0045] The embodiments of the present invention have been described above, but the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
