- As the international community strengthens the control of carbon dioxide emissions, electric vehicles have gradually become a substitute for internal combustion engine vehicles. The battery pack is one of the most important components of electric vehicles. The strength and fatigue performance of the battery support plate not only affect the performance of the vehicle but also concern the safety of the driver. In the present study, the frequency domain fatigue life of the battery support plate estimation is virtually performed on a full-scale finite element model and verified by a random vibration test. Then, with the RMS stress as the optimization objective, the frequency domain fatigue topology optimization of the battery pack support plate was carried out. The results show that the optimized structure is not only lighter in weight, but the stress at dangerous locations is significantly reduced, and the fatigue life meets the performance requirements.
