Nowadays, the application fields of lithium batteries, such as power electric vehicles, mobile phones and other products, require the mobile phones to have a long service life and require the batteries to have reliable safety performance to ensure people's safety during use.
[0003] Among them, with the increasing global attention to environmental protection and new energy development, the market demand for new energy vehicles is also growing. However, due to the use of different power systems and energy storage technologies, new energy vehicles have some differences in safety from traditional vehicles. In order to ensure the safety and reliability of new energy vehicles, it is very necessary to conduct explosion-proof tests.
[0004] When conducting explosion-proof tests on lithium batteries in the market, most of them are tested in explosion-proof boxes. However, there is no real-time monitoring equipment inside the explosion-proof box, which makes it difficult to observe the internal situation of the explosion-proof box and judge the test status of the lithium battery. Therefore, it is necessary to design a new technical solution to solve the problem, which can monitor the test environment inside the explosion-proof box in real time. Utility Model Content
