Abstract

The invention relates to the technical field of automobile collision tests, and discloses a power battery assembly bottom collision test device and test method. A test sample piece of a power battery assembly is mounted at the bottom of a test trolley, the actual collision working condition can be better fitted, and the accuracy of a test result is ensured. Obstacles are arranged along a collision path, and the maximum collision limit value capable of being borne by the power battery assembly can be obtained. By adjusting the heights of the obstacles and road shoulders, the collision situation when the test trolley passes through the obstacles and the road shoulders with different heights can be simulated, collision data under various collision working conditions can be obtained, and the test range is expanded. After a data processing module receives and processes test parameters, obtained by a data acquisition module, of the test sample piece, the fault level of the test sample piece can be obtained, a display terminal displays the test condition of the test sample piece in real time, and a tester can conveniently observe the test result in real time and evaluate the result. The whole vehicle test is avoided, the test cost is reduced, the operation is simple, and the realization is easy.

Description

technical field

[0001] The invention relates to the technical field of automobile crash tests, in particular to a bottom crash test device and a test method of a power battery assembly. Background technique

[0002] As an important part of new energy vehicles, electric vehicles have become an important product in the field of new energy vehicles. At present, new energy vehicles are becoming more and more popular. As one of the key components of electric vehicles, the safety performance of batteries directly affects the safety performance of the entire electric vehicle. Working scenarios that are prone to battery safety risks include mechanical failure, electrical failure, thermal failure, and sealing failure. Due to the moving nature of automobiles, there are many working scenarios where mechanical failures occur, such as collisions, impacts, overturns, and bottom collisions. Serious mechanical failures can easily lead to electrical failures, thermal failures, and seal fail...
