Research on Lightweight Design and Diversified Material Combinations for New Energy Vehicles

In the context of dual carbon goals and energy transition, new energy vehicles face challenges such as limited driving range and high energy consumption. Lightweight design is one of the technological measures that can be used to slow down carbon emission, expand the driving range, and improve the performance of the vehicle. The article concentrates on the study and use of lightweight technologies examining the practical application of various materials. It discusses the importance of the lightweight research, describes the major directions of technological development of materials and structures, discusses the most important multimaterial technologies, and current challenges in the sphere. Battery components, frame materials, and other structures of the vehicle body are especially considered, and the exploration of the process innovations, the topological optimization, and the choice of materials is observed. The results of the performance tests through multiple simulations as well as practical application cases indicate that it is possible to achieve the aim of safety maintenance, enhancement of structural performance and maximum costefficiency. The discoveries reached in the framework of the study are intended to address the difficulty in the profound elaboration of the automobile lightweight technologies and provide the technological progress and modernization within industry.
