Description

Technical Field

[0001] The utility model relates to the technical field of battery inspection, in particular to a testing and inspection device for retired battery packs of new energy vehicles. Background Art

[0002] At present, retired battery pack testing and inspection refers to the process of testing and inspecting battery packs that have been used for a period of time and have been retired (i.e. no longer used as a primary energy source).

[0003] The prior art has a new energy battery pack test and inspection device with an authorization announcement number of CN209979141U. The patent includes a test box, and an electric telescopic rod is fixedly installed at the bottom of the inner wall of the test box. The design of this device is to solve a series of problems that may be encountered in the test of new energy battery packs, with particular attention to the accuracy and adaptability of the test. The device divides the inside of the test box into four independent inner boxes by setting a partition. This design allows each test to be carried out in a different inner box when testing the waterproof ability, seismic resistance and pressure resistance of the new energy battery pack. This method of separating the tests effectively avoids the mutual influence between different tests, thereby ensuring the accuracy of the test results. In addition, the device is also provided with a card plate mechanism, including a fixed rod, a slide rod and a placement plate. When it is necessary to test new energy battery packs of different sizes, the distance between the slide rods on both sides can be adjusted by simply rotating the fixed rod. This design enables the device to stably clamp new energy battery packs of different sizes and place them on the top of the placement plate for testing. In this way, the device can adapt to battery packs of different specifications, improving the flexibility and practicality of the test.

[0004] However, when in use, this patent adopts detection by connecting to the device, which can easily affect the device during detection, resulting in poor detection safety. When an accident occurs during detection, this patent cannot respond in time. Utility Model Content
