An understanding of the battery cell failure characteristic is paramount due to the high risk of thermal runaway that could be initiated from a damaged cell. The risk of damage on the battery cell due to crash impact loading typically leads to a dendritic process on the liquid portion of the battery which in turn initiated an electrical short in the electric vehicle. This paper focuses on the study of the safety assessment of Lithium-ion NCA (Nickel-Cobalt-Alumina) battery subjected to crash impact loading. The characteristic of the force-displacement response of the battery cell evaluated with axial, bending, and lateral impact loadings are presented with respect to quasi-static and dynamic loading scheme. The crash impact loading scenarios described above are critical in assessing the electrical integrity of electric vehicle with Lithium-ion-based battery. The battery model is validated using the available experimental data, and the results are compared very well to the case of quasi-static loading condition. For the dynamic loading scheme, the loading velocity was varied at 5 m/s, 10m/s, 15 m/s, and 30 m/s to observe the strain-rate effect to the force-displacement response of the battery cell. The dynamic loading scheme simulation shows that, in general, the increase of the crash impact loading velocity corresponds to the increase of the peak force and the displacement of the Li-ion battery. Overall these simulation tools are very useful for assessing the electrical integrity of the Li-ion battery for electric vehicle subjected to crash impact loading.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Electrical integrity,Failure characteristics,Force-displacement response,Impact loadings,Quasi-static loading,Safety assessments,Strain rate effect,Vehicle applications[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Crash impact loading,Crashworthiness,Electric vehicle,Li-ion NCA battery[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]ACKNOWLEDGEMENT This paper was supported by USAID through Sustainable Higher Education Research Alliances (SHERA) Program – Centre for Collaborative (CCR) National Centre for Sustainable Transportation Technology.
