In order to reduce the weight and cost, the topology optimization method based on variable density method was used to carry out multi-objective topology optimization of the battery bracket. The optimization results show that the mass of the optimized battery bracket has been reduced by 16.7%, and the structural performance meets the design requirements, which has been verified through vehicle road tests. The optimization process shows that topology optimization provides a fast and effective solution for lightweight design of structures.
