The main structure of the battery pack box includes the upper-pressure cover, the upper-pressure rod, the lower box body of the battery pack, the inner frame, the lifting lug, the battery module, the single battery, and other structures.
With reference to the existing models on the market, the battery pack structure of the model is designed according to the main parameters of the model, and a simplified electric vehicle battery pack model is established by Creo and the material information is determined.
Through weight reduction and structural optimization, an innovative power battery pack design scheme is proposed, aiming to achieve a more efficient and lighter electric vehicle power system.
Through the finite element analysis software ANSYS Workbench on the electric vehicle battery pack model of Q235 steel material given a mesh cell division, finally, a model grid was constructed containing 275953 units and 546089 nodes.
Despite the remarkable progress in battery technology, there are still many challenges in optimizing the structure design of battery packs to achieve lighter, safer, and more efficient systems. Lightweight design is particularly important because reducing the overall weight of a vehicle can significantly improve energy efficiency and endurance.
