Abstract：During the driving process of new energy vehicles,the battery pack located at the bottom of the vehicle chassis is easily scratched by ground protrusions,causing safety accidents.Currently,there is a lack of awareness in the industry about the failure of battery pack bottom scraping.Therefore,this article will analyze typical failure cases in the scraping condition,obtain the structural design principles of battery pack bottom protection,and propose targeted improvement designs based on finite element simulation methods,providing guidance and reference for battery pack bottom protection design,thereby improving the overall safety of the battery pack.
