CFD-Based Evaluation of Blast Overpressure Reduction Varying Design Parameters for Pressure Relief Vents in Electric Vehicle Battery Facilities
초록
영어
As the global market share of electric vehicles (EVs) continues to grow, incidents involving battery explosions and fires are also on the rise. This alarming trend highlights the inadequacy of current evaluation technologies and design standards for facilities and human safety regarding battery-related hazards, leaving safety measures largely ineffective. To address this issue, a blast analysis of EV battery testing facilities was conducted to predict the blast loads generated during battery explosions. Furthermore, pressure relief vents were installed to evaluate their effectiveness in mitigating blast pressures. Ultimately, this study aims to develop a regression-based safety evaluation model that outlines strategies for reducing blast pressure based on the design specifications of the pressure relief vents.
