Description

Technical Field

[0001] This utility model relates to the field of pressure testing, specifically a variable frequency explosion-proof high and low temperature dual-station pressure testing device. Background Technology

[0002] A battery cell is the most basic component of a battery, typically an electrochemical device encapsulated in a metal casing. It is the unit that stores and releases electrical energy, converting chemical energy into electrical energy through chemical reactions. A battery cell usually consists of a positive electrode, a negative electrode, a separator, and an electrolyte. The positive and negative electrodes are the two polar ends of the cell, separated by a separator. Both electrodes contain active materials and are usually the sites of chemical reactions. The separator is a thin film that is permeable to charged ions; it prevents direct contact between the positive and negative electrodes but allows ions to transfer between them. To facilitate high and low temperature testing of battery cells or pouch cells, pressure testing equipment is required. The "High and Low Temperature Test Chamber and System for Battery Modules" disclosed in application number "202321884024.9" represents an increasingly mature technology. It "provides a high and low temperature test chamber for battery modules by setting up a CNC panel, allowing operators to conveniently control the operation of various mechanisms from the panel." The testing system includes a high and low temperature test chamber for battery modules, as described in any of the above technical solutions. Since the high and low temperature test system for battery modules includes a high and low temperature test chamber for battery modules and has the same effect, it will not be elaborated further here. However, this testing system still has the following drawbacks during use: While the high and low temperature test chamber can indeed perform testing operations on battery modules, the testing effect achieved solely through the aforementioned structure is not significant enough. Therefore, it is necessary to provide a testing device that can perform high and low temperature tests on individual battery cells or soft battery packs to enhance practicality. Furthermore, the heat dissipation and protection effects of this testing device are not significant enough. Therefore, it is necessary to provide a testing device that can improve its own protection effect and extend its service life. Utility Model Content

[0003] This utility model provides a variable frequency explosion-proof high and low temperature dual-station pressure testing device, which aims to solve the problems of existing pressure testing devices being inconvenient for conducting high and low temperature tests separately and for achieving a protective effect. To achieve the above objectives, this utility model provides a variable frequency explosion-proof high and low temperature dual-station pressure testing device, including a pressure testing body; The pressure testing body has a pressure relief hole on one side, a test area inside, a freezing area at the lower end of the test area, test holes on both sides, a power distribution area at the upper end, a control panel at the front end of the power distribution area, an observation window at the front end of the pressure testing body, a power switch at the bottom of the back of the pressure testing body, and a refrigeration tank inside the freezing area.

[0004] As a preferred embodiment of this utility model, a first latch is installed on one side of the pressure test body, and a second latch is installed on one side of the observation window.

[0005] As a preferred embodiment of this utility model, the lower end of the pressure test body is equipped with several casters and feet, and the pressure test body has first heat dissipation grooves on both sides.

[0006] As a preferred embodiment of this utility model, a control box is installed at the lower end of the pressure test body.

[0007] As a preferred embodiment of this utility model, both the observation window and the other side of the pressure test body are threaded with folding plates.

[0008] As a preferred embodiment of this utility model, a second heat dissipation groove is provided on the back of the pressure test body.

[0009] Compared with the prior art, the beneficial effects of this utility model are: In use, the test sample is first placed manually into the cavity of the pressure test body and the product is fixed on the fixture. Then, the external wires are led out through the test lead hole. The safety door can be closed by interlocking the first and second latches. Next, the relevant test parameters are set through the control panel, and the equipment can be started to operate normally. The placed battery begins to be tested. After the test, it is observed for 1 hour. During this process, high and low temperature tests are carried out through the test area, freezing area and refrigeration tank. The pressure relief hole can facilitate pressure relief when the pressure is too high. Finally, the product is observed through the observation window. Compared with the test system in the existing "Battery Module High and Low Temperature Test Chamber and Battery Module High and Low Temperature Test System", this utility model, through the above-mentioned structure, can facilitate the simultaneous high and low temperature pressure test of the battery cell or soft battery pack, thereby enhancing the practicality of the pressure test device. When the pressure testing device is in use, the lower heat dissipation grooves and the second heat dissipation groove on both sides and the back of the pressure testing body can achieve the effect of ventilation and heat dissipation, which initially improves the protection effect of the pressure testing device. At the same time, the caster and foot cup structure not only facilitates the movement and use of the pressure testing body, but also avoids vibration, thereby improving the safety of the pressure testing device. Compared with the pressure testing device in the existing technology "Battery Module High and Low Temperature Test Chamber and Battery Module High and Low Temperature Test System", this utility model can significantly improve the protection effect through the above-mentioned structure and thus extend the service life of the pressure testing device.
