Description

Technical Field

[0001] This application relates to the field of battery testing technology, and more specifically, to a battery testing chamber. Background Technology

[0002] The content in this section provides only background information related to this application and may not constitute prior art.

[0003] Battery testing chambers are essential equipment for evaluating battery performance, safety, and lifespan. Widely used in electric vehicles, energy storage systems, and mobile devices, they provide comprehensive testing and analysis of batteries by simulating various environmental conditions and usage scenarios. They can simulate extreme high or low temperatures to test battery performance at different temperatures, and can be configured with multiple charge / discharge modes to assess cycle life and capacity decay. They can record battery voltage and current data in real time, analyze key parameters such as internal resistance changes and energy efficiency, and verify battery safety under abnormal conditions through overcharge, over-discharge, and short-circuit protection tests. A data acquisition system records various parameters during the testing process and provides data analysis reports to help users understand the battery's true performance.

[0004] Existing battery testing chambers generally include a chamber body, with a door that is locked to the chamber body by a locking mechanism. The inner liner of the chamber body is made of stainless steel argon arc welding, while the outer liner is made of steel plate with powder coating. The hot air circulation system consists of a fan and air duct that can operate continuously at high temperatures. An independent temperature alarm device is installed inside the chamber, which automatically shuts off when the preset temperature is exceeded. A tempered glass observation window is installed on the door. When testing experimental batteries, the batteries are usually placed in a tray, and then the tray is placed inside the chamber for testing.

[0005] However, the aforementioned technologies have the following drawbacks: due to the significant differences in the size of the batteries to be tested, each battery needs to be placed on a tray, and then the tray is pushed into the chamber along the track on the chamber for testing. During the process of pushing the tray, the batteries on the tray are prone to sliding, causing them to pile up in the same place. When conducting high-temperature tests, the piled-up batteries are prone to heat accumulation, which seriously affects the normal testing of the batteries and may even cause the batteries to expand and burst, thus adversely affecting the normal use of the experimental equipment. Summary of the Invention

[0006] To address the aforementioned technical problems, the purpose of this application is to provide a battery testing chamber that can improve the reliability of battery testing, prevent battery accumulation and heat buildup, and ensure normal battery testing.

The sealing member is fixedly connected to the installation shaft along the length direction of the installation shaft. A first elastic member is provided on the placement chamber. The first elastic member is used to drive the sealing member to deflect toward the side opening of the placement slot. The side wall of the sealing member is used to abut against the side opening of the placement slot.

[0014] In some possible embodiments, a drive motor is provided on the housing, a locking block is fixedly provided at the end of the output shaft of the drive motor, a connecting sleeve is provided at the end of the drive shaft away from the lead screw along the axial direction of the drive shaft, and a slot for the locking block to be engaged is provided at the end of the connecting sleeve away from the drive shaft.

[0018] In some possible embodiments, the bottom of the placement compartment is provided with a sliding layer for sliding connection with the top of the tray.

[0019] In summary, the technical solutions of this application have at least the following advantages and beneficial effects:

[0020] 1. In actual use, when it is necessary to test the battery, first place the battery into the placement slot on the placement compartment, and seal the side opening of the placement slot with the sealing piece.

[0021] 2. During the testing process, hot air enters the placement tank through the vent at the top of the tank. During this process, the airflow through the vent is guided and directed by the guide plate. At the same time, the second drive assembly drives the rotating shaft to rotate, which in turn drives the guide plate to rotate, so that the airflow can enter the placement tank evenly, further improving the accuracy and reliability of battery testing.

[0022] 3. During the battery testing process, the first drive component moves the placement chamber on the tray, thereby moving the battery on the tray. This process further improves the uniformity of airflow entering the placement slot, thus further improving the accuracy and reliability of battery testing.

[0023] 4. When placing the pallet, the position of the sliding block on the support rod is limited by the limiting component. During the placement process, the limiting component can effectively reduce the friction between the bottom of the sliding block and the support rod, which facilitates the installation of the pallet and further improves the overall convenience of the device in actual use.

[0046] Reference Figure 7 The sealing member 32 is configured as a baffle, and an installation shaft (not shown in the figure) is rotatably provided at the opening of the placement groove 31. The sealing member is fixedly connected to the installation shaft along its length. A first elastic member (not shown in the figure) is provided on the placement chamber 3.

[0050] In actual use, as the drive motor 7 rotates, it drives the lead screw 42 to rotate. The lead screw 42 drives the strip block 24 to move in the strip groove 23, which in turn drives the placement chamber 3 to move on the tray 12. During this process, as the placement chamber 3 moves, it drives the second gear 62 to rotate on the rack 61, which in turn drives the first gear 26 to rotate, thereby achieving the effect of driving the diversion plate 51 to deflect. As one embodiment of this application, the distance between the rotating shafts 5 is greater than the length of the diversion plate 51.

[0051] Reference Figure 10 The limiting component 22 is configured as a limiting roller. A mounting groove (not shown in the figure) is provided at the bottom of the sliding block 21. Multiple mounting grooves are evenly arranged along the length of the sliding block 21.

[0053] As one embodiment of this application, a sliding layer is provided at the bottom of the placement compartment 3. The sliding layer is used to slide and connect with the top of the tray 12. The material of the sliding layer can be polytetrafluoroethylene, which can effectively reduce the sliding friction between the placement compartment 3 and the tray 12.

[0054] The implementation principle of the battery testing chamber proposed in this application embodiment is as follows:

[0055] In actual use, when the battery needs to be tested, the battery is first placed in the placement slot 31 on the placement chamber 3, and the side opening of the placement slot 31 is sealed by the sealing member 32. Since each battery on the tray 12 corresponds to one placement slot 31, the accumulation of batteries on the baffle can be effectively avoided, thereby effectively avoiding the heat accumulation caused by battery accumulation, ensuring the reliability of battery testing, and improving the protection effect on the battery and the testing equipment.
