Abstract

With the rapid development of the economy and society, and the increasing challenges related to energy and the environment, new energy vehicles have emerged as a crucial trend. Their advancement is essential for promoting renewable energy applications and the development of electrified transportation technology, ensuring energy security, mitigating shortages, and enhancing environmental quality. This paper investigates the current state of batteries and frames in new energy vehicles, summarizing and analyzing optimized design solutions that affect their performance and safety. In battery optimization, the focus is on enhancing the battery thermal management system and structure through advanced cooling techniques, material innovations, and structural modifications. Key studies demonstrate the effectiveness of direct-cooled BTMS and optimized liquid-cooled plates in maintaining optimal battery temperatures and safety. Additionally, structural enhancements in battery packs and protective measures significantly improve battery performance and durability. In frame optimization, innovations in frame structure and materials, including the integration of high-strength steel and aluminum foam, have led to improved load-bearing capacity, durability, and lightweight. Multi-dimensional optimization approaches, such as finite element analysis and topology optimization, provide comprehensive solutions for reducing stress concentrations and enhancing structural integrity. The insights gained from this research highlight the need for continued innovation in battery and frame design to achieve greater performance, safety, and sustainability in new energy vehicles, contributing to their widespread adoption and evolution.
