The safety of electric vehicles is not only restricted to the protection of the passengers but extends to the safety of the battery pack and the cells residing within. Several advancements have been made in various aspects of battery pack protection. This research aims to design an automobile’s battery pack by developing a novel structure to enhance crashworthiness. For developing the novel structure, two auxetic structures “Hexagon” and “Re-entrant,” are used which are known for their ability to withstand compressive and impact loads effectively. The structures are designed in CAD software (Fusion 360) and numerical analysis is carried out for impact testing on the designed structures. Later, the impact loading (Izod test) test is done on the developed structures by printing the structures in the form of an Izod test sample by providing the “V” notch. The obtained results are compared with the standard battery pack shapes to study the performance of the developed structures.

摘要

The safety of electric vehicles is not only restricted to the protection of the passengers but extends to the safety of the battery pack and the cells residing within. Several advancements have been made in various aspects of battery pack protection. This research aims to design an automobile’s battery pack by developing a novel structure to enhance crashworthiness. For developing the novel structure, two auxetic structures “Hexagon” and “Re-entrant,” are used which are known for their ability to withstand compressive and impact loads effectively. The structures are designed in CAD software (Fusion 360) and numerical analysis is carried out for impact testing on the designed structures. Later, the impact loading (Izod test) test is done on the developed structures by printing the structures in the form of an Izod test sample by providing the “V” notch. The obtained results are compared with the standard battery pack shapes to study the performance of the developed structures.
