Abstract
The EV market has seen unprecedented growth, which comes with its unique set of challenges in safety and structure. Their adaptive, self-healing, and energy-responsive properties make smart materials a game-changer for crumple zones and damage control in the Electric Vehicle (EV) world. This paper serves as a thorough investigation into the applications of smart materials in enhancing EV safety. This paper discusses the key applications related to crash energy management, such as shape memory alloys, magnetorheological dampers, self-healing polymers, and some examples from the automotive industry. It also stresses the incorporation of weight-saving composites, piezoelectric sensors, and sustainable coatings for structural health monitoring and durability. This review discusses its current development, obstacles and prospects to illustrate the promise of smart materials to streamline new EV design with a focus on safety, efficiency, and sustainability. This research contributes to advancing the adoption of innovative materials in next-generation EVs, addressing critical safety and performance demands.
