ABSTRACT
With the rapid growth in new energy vehicle industry, more and more new energy vehicle
battery packs catch fire or even explode due to the internal short circuit. Comparing with
traditional vehicles, the new energy vehicles industry should pay more attention to safety
of power battery pack structures. The battery pack is an important barrier to protect the
internal batteries. A battery pack structure model is imported into ANSYS for structural
optimization under sharp acceleration, sharp turn and sharp deceleration turn conditions
on the bumpy road. Based on the simulation, the battery pack structure is improved, and
suitable materials are determined. Then the collision resistance of the optimized battery
pack is verified, and the safety level is greatly improved. While ensuring the safety and
reliability of the battery pack structure, it also reduces the weight to satisfy the lightweight
design and complies with relevant technical standards.
