The research work presented in this paper discusses on “the static and dynamic analysis of battery tray for an electric vehicle” in the form of a brief review. The battery tray is one of the important components to protect batteries in electric vehicles, the dynamic and static performance of the battery tray is closely related to the safety of the whole vehicle. Therefore, it is very important to study the stress and displacement distribution of the battery tray under specific working conditions to optimize the design of the weak parts of the battery box’s stiffness and strength. Due to the advantages of high energy density and long cycle life, Li-ion batteries are being widely studied and proverbially used as power sources for electric vehicles. At first, the 3-dimensional entity model and finite element model should build and the static strength analysis is carried out on the battery tray. By analyzing the modal characteristics and the response to vibration characteristics of the battery tray. Finally, based on the static and dynamic analysis results of the battery tray, the weak points and unreasonable points are improved. The results show that the modified model has a good improvement effect and has basically reached the established design requirements, which verifies the rationality of structural improvements in the battery tray. As an important device to protect batteries in electric vehicles, the dynamic and static performance of the battery box is closely related to the safety of the whole vehicle. Therefore, it is very important to study the stress and displacement distribution of the battery box under specific working conditions to optimize the design of the weak parts of the battery box’s stiffness and strength. At first, the work establishes the three-dimensional entity model and finite element model, and the stress state of battery box under extreme conditions of steep turning and braking on uneven road surface is calculated. At the last, the static strength analysis is carried out on the battery box. By analyzing the modal characteristics and the harmonious response to vibration characteristics of the battery box, the dynamic performance of the battery box has been comprehensively mastered.
