Abstract：Due to its low cost and high-strength characteristics,high-strength rolling steel technology is becoming a future trend in the design of power battery box.In order to verify the safety performance of high-strength rolling steel power battery box,this paper conducts finite element simulation analysis and testing verification of different power battery box structures.Firstly,a finite element analysis model of high-strength rolled steel power battery box was established,and the accuracy of the finite element analysis model was verified based on modal vibration conditions.Secondly,the anti-extrusion performance and anti-bottom impact performance of the high-strength rolled steel power battery box were verified through Y-direction extrusion,bottom impact simulation,and testing.The results showed that the protective performance of the high-strength rolled steel power battery box was better than the aluminum alloy power battery box.
