Abstract
In order to avoid battery damage under extreme working conditions such as vehicle collision, which leads to the safety problems of new energy vehicles, the mechanical properties of a battery module under extrusion condition were studied in this paper. Based on finite element method, the simulation platform of battery pack extruded by sphere and cylinder is established. Maximum strain of structure is obtained, from which the end plate, side plate and busbar are identified as the most deformed components. Excessive deformation reveals the risk of damage to the battery. Therefore, 5 proposals on structural optimization are summarized to enhance the mechanical performance of this battery module.
