By studying 28 accident reports involving electric vehicles, data is collected to identify potential failure modes and evaluate their risks. The results obtained from the FMEA assessment are used to propose safety measures, considering the importance of the potential failure modes as indicated by their risk priority number (RPN).

When carrying out the FMEA, experts identify failures throughout the process chain and then try to graphically depict their CERs, which ultimately results in the failure net. After that, experts need to conduct the actual rating of the identified failure CERs in terms of their severity, probability of occurrence and detectability.
From the integrated DFMEA–PFMEA, we have identified that localized heating and a short circuit increase the risk of thermal runaway, whereas increased gas generation due to moisture or electrolyte leakage increases the risk of explosion. Manufacturing and assembling defects in the safety devices also reduce the safety of the battery.
FMMEA-enhanced design and simulation tools can enable battery manufacturers to rapidly develop new batteries by assessing the impact of chemistry and design on performance and safety.

The importance of developing an FMEA boundary diagram is that it defines the scope of the FMEA and breaks it down into different levels. A boundary diagram is a graphical illustration of the relationships between the subsystems, assemblies, subassemblies, and components within the object, as well as the interfaces with the neighboring systems and environments.
