AI Technical Summary
The test results of existing battery buffer blocks in the environmental test chamber are quite different from those of the actual application environment, resulting in inaccurate test results.
Using a test tool for a profiling base and a profiling cover plate, the actual use scenarios are simulated through structures such as the inclined surface of the storage, the inclined surface of the storage, the inclined surface of the installation, the limit column and the inclined block, to ensure that the battery buffer block is in a real environment during the test process, and to use Long and short bolt connections allow for stable placement.
It improves the accuracy of the test results, reduces the deterioration of the test process, and ensures that the test results are close to the actual working conditions.

[0002] With the rapid development of the electric vehicle industry, batteries, as its core components, have increasingly higher requirements for safety and stability. As an important component of battery protection, the performance of battery buffer blocks (EPP materials) is directly related to the service life and safety performance of the battery. During the development of battery buffer blocks, simulation tests and verifications are required. The battery buffer blocks are directly placed in an environmental test chamber for long-term thermal aging tests and high and low temperature cycle tests. However, the test results obtained by this test method are quite different from the actual application environment. Utility Model Content
