Lightweight composite battery box for innovative electric vehicle. D2H Advanced Technologies was tasked with designing a new battery box for an American EV manufacturer developing their latest electric vehicle, with strict targets for both weight and rigidity.
Composite carbon fiber materials offer excellent impact resistance, providing an additional layer of protection for the battery pack against external shocks and collisions. This characteristic enhances the safety of the battery box structure and minimizes the risk of damage to the battery cells.
However, this method requires accurate datasets obtained from experimental results. Nevertheless, the challenge in developing polymer composites for battery packs lies in ensuring that the representation of material characterization, namely flame retardancy, thermal performance, and mechanical properties, can reflect real-world conditions.
If the battery enclosure is made of polymer composites, there is a possibility of decomposition and loss of its primary functions as a structure and cover. The risk of catastrophic damage increases if the fire breaches the battery enclosure and directly affects the battery cells, resulting in thermal runaway from external abuse.
The paper also discusses the performance characteristics of composite battery pack structures, such as mechanical properties, thermal management, safety aspects, and environmental sustainability. This study aims to contribute to sharpening the direction of future research and innovations in the area of composite battery pack technology. 1.
Some considerations related to the application of polymer composites for EV battery pack. Future directions involve advancements in reinforced polymer composites through ongoing research to enhance performance and reduce costs. This includes exploring new types of fibers or other reinforcements, matrix materials, and composite architectures.
Composite materials offer several advantages that make them ideal for battery box applications. Firstly, such composites exhibit an outstanding strength-to-weight ratio, especially if they are further reinforced by particle or fiber materials, such as carbon or glass fibers [5, 6, 7].
