[0002] With the country's vigorous promotion of the electric vehicle field, electric vehicles have become the mainstream trend in the future. Among them, the electrical safety of electric vehicles has attracted more and more attention. A large number of dynamic tests are carried out on the safety performance of power batteries, such as simulated collisions with high acceleration values, dynamic extrusion tests, etc. In these tests, there are safety risks of power batteries. Some extreme high-energy tests may cause the risk of fire and explosion of power batteries.

[0003] When conducting dynamic tests on the safety performance of power batteries, it is necessary to collect test data of power batteries during the collision process, such as acceleration, force, displacement and other physical quantities. A professional data acquisition instrument is required to collect data, and usually the data acquisition instrument is fixed on the mobile platform of the battery testing equipment and participates in the entire collision process with the impact of the mobile platform. During the test, once the battery fails during the test, it will instantly cause fire and explosion.

[0004] Currently, the fastest way to extinguish a battery fire is to use fire-fighting equipment and facilities to pour or soak the sample with a large amount of water for a long time to cool down the power battery. The data acquisition instrument is an important electronic instrument with high precision and high value. During the test, it is installed on the same platform at a close distance with the sample. The process of sample fire and fire extinguishing will directly cause scrap damage to the data acquisition instrument, causing great property losses to the test, and the test data will also be lost.
