It is necessary to require the supercapacitor box to have sufficient strength and stiffness while using supercapacitor as energy storage device for electric vehicles. Therefore, it is vital for the designers to assess the safety of the mechanical structure for the energy storage supercapacitor box. However, existing studies mainly focus on the simulation of battery pack structure, and there is relatively few literatures on simulation of energy storage supercapacitor box structure. This paper takes the energy storage supercapacitor box of a specific electric truck as the research object. A finite element model of the supercapacitor box made from steel Q235 has been established, and thereafter the modal analysis and random vibration analysis are carried out in sequence. The results show that the structure of the energy storage supercapacitor box could meet the requirement of safety. Moreover, aluminum alloy 6061-T6 is used to replace Q235 for the manufacturing of supercapacitor box. Subsequently, the simulation results show that energy storage supercapacitor box made from aluminum alloy 6061-T6 could also assure modal and random vibration safety, as well as mass and emission reduction. The current study will fill the blanks of energy storage in the segmentation of supercapacitor box structure for both research and industrial field.
