Communication—Impact Behaviors of Pouch and Prismatic Battery Modules

Abstract

The responses of pouch and prismatic battery modules when they are impacted by two types of indenters from three different directions are investigated experimentally. The test results show that the failure mechanism, peak force and penetration that leads to short-circuit in modules strongly depend on the impact direction, indenter shape, cell form factor and module design. It sheds lights on the abuse tolerance of batteries in different scenarios and demonstrates that the cell type, orientation and module structure should be considered simultaneously in order to improve the battery safety in electrical vehicles.
