The usage of Electric Vehicles (EVs) and the annual production rate have increased significantly over the years. This is due to the development of rechargeable electrical energy storage system (battery pack), which is the main power source for EVs. Lithium-ion batteries (LIBs) pack is predominantly used across all major vehicle categories such as 2-wheelers, 3-wheelers and light commercial vehicle. LIB is one of the high energy-dense sources of volume. However, LIBs have a challenge to pose a risk of short circuits and battery pack explosions, when exposed to damage scenarios. In the present study, the controlled crash analysis is performed for various velocities ranging from 50 kmph to 72 kmph against an obstruction directly and at an offset from the wheel, so as to mimic the real-world crash of high-speed two-wheelers. The behavior of the battery enclosure is examined through evaluating the structural integrity of the battery enclosure used in a realistic two-wheeler after crash at various colliding velocities. The study focuses on analyzing the battery enclosure for structural deformation in mild steel and comparing with a light-weight composite material. The energy absorption behavior of the enclosure is investigated through impact simulation. Mild steel is the commonly used material for battery enclosure in EVs. Strategically the design of battery enclosure for EVs can be improved by knowing the influence of materials on weight and crashworthiness. By decreasing weight and increasing the efficiency, this optimization not only enhances overall safety, but also improves the vehicle performance. As the electric vehicle landscape evolves, these findings become instrumental in shaping safer, efficient, and high-performing EVs. The results indicate that carbon fiber based composites are better compared to mild steel based on the structural integrity.
