Battery aging is closely related to factors such as its use environment, temperature, vibration, external force, etc. Traditional battery life test methods mainly rely on battery charge and discharge tests in static environments, or placing batteries in a constant temperature and temperature-controlled device for battery charge and discharge tests.

[0003] The battery multi-temperature zone high and low temperature test chamber is a device used to test the performance of batteries under different temperature environments. The test chamber can simulate the working state of batteries under extreme high and low temperature conditions to evaluate their safety, stability and reliability, and judge the degree of battery aging to determine whether the battery can continue to 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 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 detect the performance of batteries in a static state, and do not consider the performance degradation of batteries under motion and vibration conditions.

[0015] The beneficial effects of the present invention are: 1. The multi-temperature zone high and low temperature test box for batteries described in the present invention can detect the aging of the battery body at different temperatures through a variable temperature box and a discharge detector. On this basis, the gas flow is controlled by an air pump, and the power generated by gas delivery is used to continuously rotate the connecting shaft and the counterweight. Under the action of the counterweight, the connecting plate and the battery body fixed on the connecting plate can be vibrated, so that the data obtained can be compared with the data of the static detection of the above-mentioned battery body, so as to obtain more accurate data; through the vibration test with power on, the impact of these changes on the performance of the battery body can also be monitored in real time, especially the impact on the parameters such as the capacity, internal resistance, and temperature of the battery body.

[0016] 2. The multi-temperature zone high and low temperature test box for batteries described in the present invention can not only drive the battery body to vibrate, but also make the impact plate rotate continuously through the continuous vibration of the connecting plate. Since the vibration of the battery body will hit the impact plate, the two will collide with each other, and the aging condition of the outer shell of the battery body can be detected. Moreover, due to the rotation of the impact plate, a rotational pulling force will be generated, which will change the direction of the force of the impact plate on the battery body, thereby further detecting the aging degree of the battery outer shell. During the rotation of the impact plate, the second threaded plate will also continuously reciprocate up and down. With the help of the second threaded plate, the position of the impact plate can be controlled, so that the impact distance between the impact plate and the battery body will continuously change, and different distances have different impact effects, thereby further detecting the aging degree of the battery body.

[0017] 3. The multi-temperature zone high and low temperature test box for batteries described in the present invention can rotate the first rotating shaft through an air pump. While driving the counterweight to rotate, the first rotating shaft will also drive the protrusion to rotate. The rotation of the protrusion can cooperate with the second spring to make the piston continuously move inside the fixed box, so that the piston can continuously extract and infuse gas through the second connecting pipe, so that the air pressure of the gas entering the air turntable fluctuates. The fluctuating air pressure will cause the speed of rotation of the hollow turntable to fluctuate, so that the rotation speed of the counterweight will also fluctuate. Finally, the connecting plate will drive the vibration frequency of the battery body to fluctuate, so that the battery body can be used in many ways, and the speed of the vibration frequency will also affect the rotation speed of the impact plate, which can change the impact effect between the impact plate and the battery body, thereby further performing aging detection on the battery body.

[0022] Please refer to Figure 2 , Figure 4 , Figure 5 The placement mechanism includes a placement rack 701, the placement rack 701 is located below the connecting plate 506, and the battery is located inside the placement rack 701; a screw 702 is fixedly connected to the placement rack 701, the screw 702 passes through the connecting plate 506 and extends to the top of the connecting plate 506, a threaded ring 704 is threadedly connected to the screw 702, and a plurality of latch teeth 703 are fixedly connected to the threaded ring 704; Rotate the threaded ring 704 to disengage the threaded ring 704 from the screw 702, so that the placement rack 701 can be removed from the connecting plate 506. Subsequently, place the battery body 3 inside the removed placement rack 701, and then continue to fix the placement rack 701 on the connecting plate 506 by reversing the disassembly method. When the battery body 3 is fixed, connect the discharge detector 2 to the battery body 3 through a wire. When the wire is connected, the aging condition of the battery body 3 can be detected, and by controlling the variable temperature box 1 to change the temperature inside the variable temperature box 1, the aging condition of the battery body 3 can be further detected.

The gas input into the first connecting pipe 403 will enter the hollow turntable 406 and rotate. Due to the effect of the bent pipe 407, there will be a reaction force after the gas is ejected, so that the hollow turntable 406 rotates. The rotation of the hollow turntable 406 will drive the first rotating shaft 504 to rotate. The first rotating shaft 504 drives the first reciprocating screw rod 507 to rotate. The rotation of the first reciprocating screw rod 507 will drive the connecting shaft 508 to rotate. The rotation of the connecting shaft 508 will drive the counterweight block 509 to rotate.
