Batteries have various sizes and can be configured into different layouts in battery pack on electric vehicles. Crash safety performance is one of the key requirements in choosing battery geometric characteristics and designing layout of battery cells in battery pack. In this study, we compared impact responses of different configurations and geometric characteristics of battery cells under side pole impact. The side pole impact is a relatively dangerous collision type for electric vehicles, often causing large deformation and damage to the battery. Using a production battery pack, we first conducted side pole impact tests with sled tester, and then simulated the test configuration.
