Design Optimization and Analysis of Robust and Reliable Battery Tray for Electric Vehicle against Collision

Abstract

The safety and durability of battery brackets in electric vehicles (EVs) are of utmost importance to ensure the reliable performance and protection of battery packs. Impact testing plays a critical role in evaluating the structural integrity and crashworthiness of battery brackets subjected to various impact scenarios. This abstract presents an overview of the research conducted on impact testing for battery brackets in EVs. Studies have focused on experimental tests, numerical simulations, and finite element analysis to assess the impact performance of battery brackets, which is affected by maximum load (5000N), applied on bracket. Different impact scenarios, including frontal collisions, side impacts, and high-speed loading, have been considered to understand the response of battery brackets the von mises stress, deformation, Equivalent stress. The research highlights the need for rigorous impact testing to ensure the safety and reliability of battery brackets in EVs. By combining experimental tests with numerical simulations, researchers have gained valuable insights into the failure modes, deformation characteristics, and energy absorption capacity and stress formations in battery brackets. These findings have led to recommendations for optimized designs, improved material selection, and enhanced crashworthiness of battery brackets. During a crash, the battery and its bracket are subjected to significant forces and accelerations. The objective of crash testing is to ensure that these components can withstand these forces and protect the battery from damage or the risk of thermal runaway. The battery bracket's role is to secure the battery in place and prevent excessive movement during an impact, thereby safeguarding both the battery and the vehicle's occupants.
