Lightweight Materials Contribution for the Development of Battery Management Systems in Electric Vehicles

Increasing use of electric vehicles (EVs) calls for efficient, high-performance, and light-weight battery management systems (BMSs). New materials presented in this chapter like polymer composites, metal–organic frameworks (MOFs), and nanostructured components are covered in an endeavor to achieve improved energy density, thermal management, and security. The described materials make batteries lighter in weight without sacrificing structural stiffness, thermal conductivity, and electrical resistance. Nanomaterial breakthroughs like graphene and carbon nanotubes will lower thermal runaway risk, preventing major safety concerns in next-generation BMS designs. Furthermore, the chapter is focused on bio-based polymers and recyclable composites minimizing environmental impact without sacrificing durability, wear resistance, and corrosion resistance. Sustainable production methods in light alloys, polymeric matrices, and ceramic composites are consistent with contemporary engineering practices. Computational modeling and AI-based techniques maximize material properties and simplify design, providing accuracy and efficiency in manufacturing. Case studies of real-world applications illustrate the contribution of lightweight materials to energy efficiency, dependability, and sustainability in commercial EVs. The chapter is completed with some vision on smart materials and multifunctional composites, which has the ability to address significant design challenges. It is of relevance to researchers, engineers, and industry specialists looking to adopt lightweight materials to enable better performance, safety, and sustainability in next-generation EV technology.
