There are multiple dynamic crash events in reality, and power batteries may have great safety hazards after crashing; therefore, the safety of power batteries in such cases has attracted much attention from vehicle manufacturers and the public. Currently, there are no clear standards for the impact and harm of crash on batteries. In this study, the authors intended to identify the characteristic parameters of simulated crash test of power batteries based on typical crash scenarios of NEVs, so as to develop test tools that can simulate the dynamic crash of power batteries, and analyze their performance under different dynamic crash parameters, thus providing a method for further studying the dynamic crash of power batteries.
