Lightweight is one of the key technologies to improve the range of new energy vehicles. How to achieve a balance between cost and weight reduction is a challenge faced by major car companies. By collecting and organizing lightweight manufacturing, assembly, and design technologies, feasible technical solutions are explained through examples of typical parts in the body, interior and exterior decorations, chassis, and three electrical fields. Research suggests that lightweight materials and component structure optimization are generally used to achieve light weighting. Among them, steel aluminum hybrid body, integrated die-casting, and component integration design are currently hot topics and also the direction for the development of vehicle weight reduction technology.
