Aiming to improve the collision safety of power battery system, the study established the finite element models of the whole bus skeleton, power battery system and moving deformable barrier. A side collision was simulated on the position of battery box of the bus based on the collision law. The work carried out equivalent stress analysis of battery module and deformation analysis of battery pack and the rear panel of battery box. Measures were put forward to improve the collision safety of power battery syste…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
