2.5 Burst Disc & Pressure Relief Design

For safety, the design must account for scenarios where cells or the module might generate significant internal pressure, particularly during fault conditions like thermal runaway. Burst disc and pressure relief design involves incorporating features such as rupture discs or vents that are engineered to safely release this excess pressure before it can cause a catastrophic failure of the module enclosure. Designers must define precise activation pressures and ensure adequate flow rates for these safety devices, often using pressure vessel design codes and potentially CFD (Computational Fluid Dynamics) for analysis.
