The battery housing beneath the passenger compartment floor improves the vehicle's center of gravity, safety in impacts, and maintenance ease. Using a composite of BASALT fiber, 3 mm PP sheet, glass fiber, and epoxy reinforces the battery case for strength and impact resistance. Integrating this structure stiffens the vehicle body, enhancing safety and performance. It optimizes materials, potentially reducing weight and improving efficiency. Testing to validate these solutions would demonstrate real-world benefits. Electric vehicles are increasingly prevalent, posing challenges due to large, heavy, and costly battery packs. Positioning them below the passenger floor enhances protection and maintenance ease. Integrating the battery packs structure stiffens the body, crucial for safety. Considerations for impact protection against fixed obstacles, like poles, are vital. Our battery cases, crafted from BASALT fiber, 3 mm PP sheet, and glass fiber in a composite, bolster safety while supporting the vehicle structure. The design and material selection of the battery enclosure, with the mentioned composite materials, can significantly contribute to the overall safety measures of the vehicle in such scenarios. It optimizes the use of materials and space while potentially reducing the weight of the vehicle, contributing positively to its energy efficiency and performance. Have you conducted simulations or tests to validate the proposed solutions? It would be intriguing to explore how these engineering analyses translate into real-world performance and safety enhancements for electric vehicles. © 2025 Elsevier B.V., All rights reserved.
